The present invention is directed to a method and system for disaggregating and connecting A / V components, and communicating A / V content stream information. An A / V stream from a source device is packaged for transmission over an IP network to one or more output devices. A brick device enables the integration of legacy A / V systems into the network supported A / V system. The brick device operates to provide analog signal and IP protocol conversion, along with the synchronization of received A / V stream data packets. The rendering and play of the A / V stream content on multiple output devices is synchronized to overcome distortions and other network idiosyncrasy and to facilitate a pleasant user experience.

A power supply rail controller operates on an analog component having a signal input, a power input and a signal output. A voltage controller provides a control output responsive to the signal output. A power supply generates a voltage for the power input, where the voltage is responsive to the control output. The voltage is reduced in magnitude to reduce power dissipation and increased in magnitude to avoid signal distortion.

Various corporate, industry, and regulatory guidelines, best practices and standards are used in establishing acceptable levels of accuracy for volume dimensioning systems used in commerce. A volume dimensioning system can determine at least one distortion value that is indicative of an amount of distortion present in the system and responsive to the amount of distortion, autonomously alter or adjust the units of accuracy of information reported by the system. Such alteration or adjustment of units of accuracy may be performed based on an assessment of the distortion relative to a number of distortion thresholds. Responsive to the assessment, the volume dimensioning system can adjust a unit of accuracy in a representation of volume dimensioning related information.

Volume dimensioning employs techniques to reduce multipath reflection or return of illumination, and hence distortion. Volume dimensioning for any given target object includes a sequence of one or more illuminations and respective detections of returned illumination. A sequence typically includes illumination with at least one initial spatial illumination pattern and with one or more refined spatial illumination patterns. Refined spatial illumination patterns are generated based on previous illumination in order to reduce distortion. The number of refined spatial illumination patterns in a sequence may be fixed, or may vary based on results of prior illumination(s) in the sequence. Refined spatial illumination patterns may avoid illuminating background areas that contribute to distortion. Sometimes, illumination with the initial spatial illumination pattern may produce sufficiently acceptable results, and refined spatial illumination patterns in the sequence omitted.

A system and method for measuring an item's dimensions using a time-of-flight dimensioning system is disclosed. The system and method mitigate multipath distortion and improve the accuracy of the measurements, especially in a mobile environment. To mitigate the multipath distortion, an imager captures an image of an item of interest. This image is processed to determine an illumination region corresponding item-of-interest's size, shape, and position. Using this information, an adjustable aperture's size, shape, and position are controlled so the light beam used in the time-of-flight analysis substantially illuminates the illumination region without first being reflected.

A method and system is described which allows users to identify (pre-recorded) sounds such as music, radio broadcast, commercials, and other audio signals in almost any environment. The audio signal (or sound) must be a recording represented in a database of recordings. The service can quickly identify the signal from just a few seconds of excerption, while tolerating high noise and distortion. Once the signal is identified to the user, the user may perform transactions interactively in real-time or offline using the identification information.

A user configurable variable mode pulse indicator provides a user the ability to influence outputs indicative of a pulse occurrence at least during distortion, or high-noise events. For example, when configured to provide or trigger pulse indication outputs, a pulse indicator designates the occurrence of each pulse in a pulse oximeter-derived photo-plethysmograph waveform, through waveform analysis or some statistical measure of the pulse rate, such as an averaged pulse rate. When the configured to block outputs or not trigger pulse indication outputs, a pulse indicator disables the output for one or more of an audio or visual pulse occurrence indication. The outputs can be used to initiate an audible tone “beep” or a visual pulse indication on a display, such as a vertical spike on a horizontal trace or a corresponding indication on a bar display. The amplitude output is used to indicate data integrity and corresponding confidence in the computed values of saturation and pulse rate. The amplitude output can vary a characteristic of the pulse indicator, such as beep volume or frequency or the height of the visual display spike.

The invention relates to an LED package for facilitating color mixing using a diffuser and a manufacturing method of the same. The LED package includes a substrate with an electrode formed thereon, and an LED chip mounted on the substrate. The LED package also includes an encapsulant applied around the light emitting diode chip, containing a diffuser. The LED package further includes a lens part disposed on the light emitting diode chip and the encapsulant to radiate light in a wide angle. The LED package allows light from the light emitting diode chip to be emitted out of the package without distortion. The invention allows light to exit through the encapsulant containing the diffuser and the lens part, achieving uniform diffusion and emission of light from the LED chip, thereby increasing a radiating angle and obtaining a uniform light source.

A wearable platform embodied in a belt or flattened patch-like central body shaped to conform to the abdomen provides physiological monitoring of soldiers during field operations or trauma victims at accident sites and makes health state assessments. The platform includes sensors for heart rate, body motion, respiration rate and intensity, and temperature and further contains a microprocessor and short range transmitter. The respiration sensor uses conductive ink in a novel manner. A small square of the ink is coated on an arched structure so that flexing of the arch either to increase or decrease its radius of curvature modifies the resistance of the structure. This is utilized to set the unstressed resistance of the arch structure and to allow a greater range of resistance values capable of measuring distortions in different deformations of the arch. The respiration sensor supplements the motion information provided by an accelerometer sensor.

A method for operating a memory device (24) includes encoding data using an Error Correction Code (ECC) and storing the encoded data as first analog values in respective analog memory cells (32) of the memory device. After storing the encoded data, second analog values are read from the respective memory cells of the memory device in which the encoded data were stored. At least some of the second analog values differ from the respective first analog values. A distortion that is present in the second analog values is estimated. Error correction metrics are computed with respect to the second analog values responsively to the estimated distortion. The second analog values are processed using the error correction metrics in an ECC decoding process, so as to reconstruct the data.

The distortion in the sub-carrier signals is determined by transmitting known values that are incorporated into the preamble portion of the frame and / or are incorporated into pilot symbols that are inserted into the data portion of the frame. The receiver typically receives these known values in a distorted form and then processes the distorted values together with the original known values to obtain a channel response. The channel response is then used to estimate the frequencies at which the channels are received.

The subject invention pertains to a method and apparatus for placing a minimally-invasive access with respect to a patient's bone or other non-soft tissue. The subject invention can use a drilling machine incorporating an ultrasound motor. The subject drilling machine can be applied to sample, for example, bone biopsies under MRI control. In a specific embodiment, the subject ultrasound motor can be completely manufactured of non-magnetic materials, such as plastics, titanium, and titanium alloy, or ceramics and piezoceramics. The subject drilling apparatus can be placed into an MRI near field without influencing the image quality, and without the drilling apparatus itself being disturbed by the MRI magnet, gradient, or high-frequency field. The subject invention can incorporate good shielding with the subject drilling apparatus use of these materials, and can achieve minimal, if any, image distortions or so-called artifacts. Thus, the subject invention can involve the problem by use of non-magnetic materials of low magnetic susceptibility for the design of an actuation unit.

A mitral annuloplasty ring that has an outward and an upward posterior bow. The ring defines a closed, modified oval shape with a minor-major axis dimension ratio of between about 3.3:4 to 4:4. The ring is made of a material that will substantially resist distortion when subjected to the stress imparted thereon when the ring is implanted in the mitral valve annulus of an operating human heart. As a result, the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, or Barlow's syndrome, in which the leaflets tend to be elongated or floppy.

The present invention relates to using a trap-rich layer, such as a polycrystalline Silicon layer, over a semiconductor substrate to substantially immobilize a surface conduction layer at the surface of the semiconductor substrate at radio frequency (RF) frequencies. The trap-rich layer may have a high density of traps that trap carriers from the surface conduction layer. The average release time from the traps may be longer than the period of any present RF signals, thereby effectively immobilizing the surface conduction layer, which may substantially prevent capacitance and inductance changes due to the RF signals. Therefore, harmonic distortion of the RF signals may be significantly reduced or eliminated. The semiconductor substrate may be a Silicon substrate, a Gallium Arsenide substrate, or another substrate.

A method for operating a memory (28) includes storing data in a group of analog memory cells (32) of the memory as respective first voltage levels. After storing the data, second voltage levels are read from the respective analog memory cells. The second voltage levels are affected by cross-coupling interference causing the second voltage levels to differ from the respective first voltage levels. Cross-coupling coefficients, which quantify the cross-coupling interference among the analog memory cells, are estimated by processing the second voltage levels. The data stored in the group of analog memory cells is reconstructed from the read second voltage levels using the estimated cross-coupling coefficients.

A disposable absorbent article worn about the lower torso of a wearer includes at least one serviceable indicium that facilitates the process of fitting the absorbent article to the wearer by providing an apparent visual and physical indication when the article is not properly fitted. The apparent visual and physical indication includes a detectable distortion of the waist opening, the leg openings or both the waist opening and the leg openings. The detectable distortion includes at least one serviceable indicium disposed on a portion of the waist opening or leg opening or both that becomes flipped in towards an inner surface of the article or flipped out towards the outer surface of the article when the article is not properly fitted.

An adaptive underwater camera housing and control interface for use with a broad range of camera brands and models. The camera housing is preferably formed of front and rear housing sections that are molded of clear transparent plastic and arranged to be moved between an open position for mounting a camera within the housing and a closed position in which the housing provides a watertight enclosure for protecting and communicating with a camera. Residing in the housing are a controller and communications interface by which a camera can be operated from outside the housing. Magnetic signals are preferably passed to the controller by external signal buttons operated by the user. The external signal buttons do not penetrate the interior surfaces of the housing thereby enhancing its water tightness. The housing is provided with a truncated hemispherical lens through which a camera views scenes to be photographed to reduce distortion and not foreshorten viewing angle and a flat window and diffuser for providing controlled artificial illumination to a scene.

A capacitive touch sensitive position sensor is provided which has a substrate defining a touch sensitive platform. First and second resistive bus-bars arranged spaced apart on the substrate. A conductive sensing area is formed between the bus bars and is constructed with first and second conductive elements connected to the first and second resistive bus-bars respectively, and spaced apart from each other by non-conducting gaps, so that currents induced in the conductive sensing area flow towards the bus-bars, but are prevented from flowing in a direction parallel to the bus-bars. This design removes pin-cushion distortion and enhances linearization of the output signals. Because the sensing region is not galvanically coupled from one bus bar to the other, the voltage gradients remain uniform and undistorted. Capacitive coupling from one side to the other does not produce a distortion component provided that the capacitance is allowed to fully charge and discharge across all locations in the sensing region.

A wafer carrier used in wafer treatments such as chemical vapor deposition has pockets for holding the wafers and support surfaces for supporting the wafers above the floors of the pockets. The carrier is provided with locks for restraining wafers against upward movement away from the support surfaces. Constraining the wafers against upward movement limits the effect of wafer distortion on the spacing between the wafer and the floor surfaces, and thus limits the effects of wafer distortion on heat transfer. The carrier may include a main portion and minor portions having higher thermal conductivity than the main portion, the minor portions being disposed below the pockets.

Input text data undergoes language analysis to generate prosody, and a speech database is searched for a synthesis unit on the basis of the prosody. A modification distortion of the found synthesis unit, and concatenation distortions upon connecting that synthesis unit to those in the preceding phoneme are computed, and a distortion determination unit weights the modification and concatenation distortions to determine the total distortion. An Nbest determination unit obtains N best paths that can minimize the distortion using the A* search algorithm, and a registration unit determination unit selects a synthesis unit to be registered in a synthesis unit inventory on the basis of the N best paths in the order of frequencies of occurrence, and registers it in the synthesis unit inventory.

A method and apparatus for use in improving the linearity characteristics of MOSFET devices using an accumulated charge sink (ACS) are disclosed. The method and apparatus are adapted to remove, reduce, or otherwise control accumulated charge in SOI MOSFETs, thereby yielding improvements in FET performance characteristics. In one exemplary embodiment, a circuit having at least one SOI MOSFET is configured to operate in an accumulated charge regime. An accumulated charge sink, operatively coupled to the body of the SOI MOSFET, eliminates, removes or otherwise controls accumulated charge when the FET is operated in the accumulated charge regime, thereby reducing the nonlinearity of the parasitic off-state source-to-drain capacitance of the SOI MOSFET. In RF switch circuits implemented with the improved SOI MOSFET devices, harmonic and intermodulation distortion is reduced by removing or otherwise controlling the accumulated charge when the SOI MOSFET operates in an accumulated charge regime.

A method of modulating communications signals, such as optical fiber, wired electronic, or wireless signals in a manner that facilitates automatic correction for the signal distortion effects of echoes and frequency shifts, while still allowing high rates of data transmission. Data symbols intended for transmission are distributed into N×N matrices, and used to weigh or modulate a family of cyclically time shifted and cyclically frequency shifted waveforms. Although these waveforms may then be distorted during transmission, their basic cyclic time and frequency repeating structure facilitates use of improved receivers with deconvolution devices that can utilize the repeating patterns to correct for these distortions. The various waveforms may be sent in N time blocks at various time spacing and frequency spacing combinations in a manner that can allow interleaving of blocks from different transmitters. Applications to channel sounding / characterization, system optimization, and also radar are also discussed.
