An application for a device includes at least two speakers and at least two-channels of audio. The at least two-channels of audio are selectively routed to the at least two speakers. Routing of the audio to the speakers is made based upon an orientation of the device. The orientation of the device and therefore the speaker configuration is either manually changed by a viewer input or is automatically detected such as when a hand-held device is rotated, for example, to view a display of the device in portrait mode instead of landscape mode.

A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and / or control external devices.

A wearable communication device includes a bone conduction actuator which is applicable for being in contact with a user's wrist, hand, back of the hand, finger or nail in order to transmit voice signals. The user inserts the user's finger into the user's ear canal, or touches the user's finger to a part near the user's ear, or puts the user's fingertip or nail on the user's ear canal so as to block the user's ear canal when the user uses the wearable communication device. Also, the wearable command input device includes a first part for detecting shock or acceleration which arises when the user taps the user's fingertip on the surface of an object or when the user taps the fingertips mutually and which is transmitted through the user's finger, a second part for detecting specific frequency components which are included in signals from the first part and for detecting the presence or the absence of the tap of the finger of the user, and a part for determining and executing commands based on series of signals output from the second part.

The disclosure relates to General Synchronized Vibration devices that provide haptic feedback to a user and improve the performance of existing vibratory devices. Different actuator types may be employed to provide synchronized vibration, including linear rotary actuators, rotating eccentric mass actuators including interleaved rotating mass actuators, and rocking mass actuators. A controller sends signals to one or more driver circuits to provide adjustment of vibration magnitude, frequency, and direction of the actuators. The system may apply forces onto an object, and a sensor measures a feature(s) of the object. This information is provided to a vibration device controller, which can then modify the vibration waveform to improve overall system performance. Fourier synthesis can be used to approximate arbitrarily shaped waveforms by controlling the phase and frequency of vibration actuators. These waveforms can include asymmetry where the peak force in one direction is higher than the peak force in another direction.

Disclosed are appendage mountable electronic systems and related methods for covering and conforming to an appendage surface. A flexible or stretchable substrate has an inner surface for receiving an appendage, including an appendage having a curved surface, and an opposed outer surface that is accessible to external surfaces. A stretchable or flexible electronic device is supported by the substrate inner and / or outer surface, depending on the application of interest. The electronic device in combination with the substrate provides a net bending stiffness to facilitate conformal contact between the inner surface and a surface of the appendage provided within the enclosure. In an aspect, the system is capable of surface flipping without adversely impacting electronic device functionality, such as electronic devices comprising arrays of sensors, actuators, or both sensors and actuators.

Estimates of a communication system configuration, such as a DSL system, are based on operational data collected from a network element management system, protocol, users and / or the like. The operational data collected from the system can include performance-characterizing operational data that typically is available in an ADSL system via element-management-system protocols. Generated estimates and / or approximations can be used in evaluating system performance and directly or indirectly dictating / requiring changes or recommending improvements in operation by transmitters and / or other parts of the communication system. Data and / or other information may be collected using “internal” means or may be obtained from system elements and components via email and / or other “external” means. The likelihood of a model's accuracy can be based on various data, information and / or indicators of system performance, such as observed normal operational data, test data and / or prompted operational data that shows operating performance based on stimulation signals. One example of such prompted data uses frequency carrier masks to approximate the Hlog of a given channel, including information regarding bridged taps, attenuation, etc.

A digital broadcasting system and a data processing method are disclosed. Herein, additional encoding is performed on mobile service data, which are then transmitted, thereby providing robustness in the processed mobile service data, so that the mobile service data can respond more strongly against fast and frequent channel changes. The transmitting system includes a first encoding module grouping a plurality of inputted mobile service data bytes so as to form a RS frame and performing error correction encoding in RS frame units, a second encoding module encoding the primarily encoded and outputted data at a coding rate of G / H, wherein G is smaller than H (i.e., G<H), and a third encoding module performing trellis encoding on the secondarily encoded and outputted data.

There is provided a highly reliable transmission / reception integrated radio-frequency apparatus which can achieve a high communication quality in a cable modem. A reception RF signal is input to a reception system block via an input / output terminal, converted to an intermediate-frequency signal, and output from a terminal. An output terminal of a transmission processing section of a transmission system block is connected to the input / output terminal via an overvoltage protection circuit, a high-pass filter functioning as a countermeasure to overvoltage, and a low-pass filter for suppressing harmonics produced from the high-pass filter.

A digital radio frequency transport system that performs bi-directional simultaneous digital radio frequency distribution is provided. The transport system includes a digital host unit and at least two digital remote units coupled to the digital host unit. The bi-directional simultaneous digital radio frequency distribution is performed between the digital host unit and the at least two digital remote units.
