Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server. Each of the plurality of viewers may configure the received video and audio signals independent of any other viewer and may generate alerts based on the video and audio content.

The present invention provides new methods and systems for treating myopia progression in myopic patients who also exhibit near point esophoria, esophoria at near, eso fixation disparity, or eso associated phoria by selectively prescribing bifocal contact lenses to such patients. Near point eso fixation disparity may include esophores, low exophores, and orthophores. One method for controlling myopia progression comprises identifying a near point esophoric myopic patient, measuring an amount of fixation disparity, and prescribing a bifocal contact lens add power prescription. The bifocal add power prescription is based on the fixation disparity measurement and a distance prescription for the patient's eye.

A substrate processing apparatus for processing substrates prevents the substrates from contaminating as they are transferred. The apparatus includes a container, like a FOUP, for containing substrates, at least one processing chamber where the substrates are processed, a substrate transferring module including a substrate transfer chamber and at least one load port for supporting a container, and a contamination controlling system for the substrate transfer chamber. The contamination controlling system includes a purge gas supply inlet connected to the substrate transfer chamber, and a gas circulating tube for recycling the purging gas to circulate through the chamber. The substrate transfer chamber is purged using the purging gas to remove moisture and contaminating materials from the substrate transfer chamber. The formation of particles on the substrate otherwise caused by a reaction between the moisture and contaminating materials while the substrate is standing by in the container can be prevented.

A method for removing an occlusion is provided comprising introducing a transverse mode ultrasonic probe into a blood vessel, positioning the probe in proximity to the occlusion, and transmitting ultrasonic energy to the probe, until the occlusion is removed. The probe has a small cross-sectional lumen and is articulable for navigating in a tortuous vessel path. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion. The probe can also be used with a balloon catheter. The probe, sheaths, and catheter can be provided in a sharps container which further provides a means of affixing and detaching the probe from an ultrasonic medical device.

There is provided a series of novel particulate stabilized lithiated compounds which can be utilized as cathodic materials in lithium ion battery cells. Each particle of the material defines an inner lithiated metal oxide core which acts as an intercalation cathode. A lithium ion conductor coating surrounds the core to stabilize the latter and to improve the electrochemical properties of the material.

Disclosed is an apparatus and method for controlling an asymmetric modular multilevel converter which allow numerous levels to be expressed according to a combination of modules each using a different voltage, comprising: an asymmetric arm configured with a full bridge and a half bridge; and a control method of controlling each capacitor level of the full bridges and capacitor level of the remaining half bridges to be different from one another by a full bridge structure, wherein each module configuring the asymmetric arm uses a different voltage and an output voltage is expressed by a combination thereof.

The present invention is directed to a power converter that can be used to interface a motor 4 that requires variable voltage at variable frequency to a supply network (bus) providing a nominally fixed voltage and nominally fixed frequency. The power converter includes a first active rectifier/inverter 10 electrically connected to the stator of the motor 4 and a second active rectifier/inverter 14. Both the first and second active rectifier/inverters include a plurality of semiconductor power switching devices. A dc link 12 is connected between the first active rectifier/inverter and the second active rectifier/inverter. A filter 16 is connected between the second active rectifier/inverter and the supply network and includes network terminals. The power converter includes a first controller 18 for the first active rectifier/inverter and a second controller 20 for the second active rectifier/inverter. The first controller 18 uses a dc link voltage demand signal VDC_MOT* indicative of a desired dc link voltage to control the semiconductor power switching devices of the first active rectifier/inverter 10 to achieve the desired level of dc link voltage that corresponds to the dc link voltage demand signal. The second controller 20 uses a power demand signal P* indicative of the level of power to be transferred to the dc link 12 from the supply network (bus) through the second active rectifier/inverter 14, and a voltage demand signal VBUS* indicative of the voltage to be achieved at the network terminals of the filter 16 to control the semiconductor power switching devices of the second active rectifier/inverter 14 to achieve the desired levels of power and voltage that correspond to the power and voltage demand signals. The power converter can be employed in a marine propulsion system where the rotor of the motor 4 is used to drive a propeller assembly 2.

There is disclosed an apparatus for controlling the processing load of a scalable video decoder that decodes an incoming scalable video bit stream and generates a baseband video signal. The apparatus comprises: 1) an analyzer circuit for measuring at least one characteristic of the incoming scalable video bit stream and generating at least one video parameter associated with the at least one characteristic; and 2) a processor load controller for receiving the at least one video parameter and, in response thereto, controlling a level of decoding of the incoming scalable video bit stream performed by the scalable video decoder.

A low energy process for producing acetic acid by the carbonylation of methanol is disclosed. The process involves a rhodium-catalyzed system operated at less than about 14% water utilizing up to 2 distillation columns. The process is preferably controlled such that the product stream has a low level of propionic acid impurity and the level of aldehyde impurities is minimized by way of aldehyde removal or minimizing aldehyde generation. The level of iodides is controlled by contacting the product, at elevated temperatures, with ion exchange resins. In preferred embodiments, at least one silver or mercury exchanged macroreticular strong acid ion exchange resin is used to purify the product. The high temperature treatment provides the added benefit of controlling the Color Value (Pt-Co units) of the product stream.
