Abstract: An audio amplifier system includes a delta-sigma modulator configured to receive an m-bit digital audio input signal and to generate a pulse density modulated signal based on the m-bit digital audio input signal. An analog power stage is coupled to the delta-sigma modulator to receive the pulse density modulated signal and amplify the pulse density modulated signal to generate an amplified pulse density modulated signal. A feedback circuit is coupled to the delta-sigma modulator and the analog power stage. The feedback circuit is configured to receive the amplified pulse density modulated signal and the pulse density modulated signal and to determine a digital error signal representative of a difference between the amplified pulse density modulated signal and the pulse density modulated signal. The feedback circuit is further configured to provide the digital error signal to the delta-sigma modulator for applying the digital error signal to a representation of the m-bit digital audio input signal.

Abstract: This invention relates to interdigitated electrodes for power electronic and optoelectronic devices where field and current distribution determine the device performance. Described are geometries based on rounded asymmetrical fingers and electrode bases of varying width. Simulations demonstrate benefits for reducing self-heating and thermal power loss, which reduces overall on-state resistance and increases reverse break down voltages.

Abstract: A mounting system for a portable device includes a top case, a bottom case coupled to the top case, and first and second arms on two sides of the top case and the bottom case and spaced away from each other. Each of the first and second arms include a first section and a second section. In a first state where the top case is pushed toward the bottom case and a first distance is between the first and second arms, the first sections protrude outside from the top case. In a second state where the second sections are pushed toward each other and a second distance smaller than the first distance is between the first and second arms, the first sections do not protrude outside from the top case or protrude outside from the top case less than in the first state.

Abstract: An adjustable case for a mobile electronic device. The case has a bottom including a main chassis, a fixed holding member fixedly connected with the main chassis, a sliding holding member slidedly connected to the main chassis to slide back and forth, and a tension mechanism biasing the sliding holding member towards the fixed holding member so that the fixed holding member and the sliding holding member squeeze the mobile electronic device when fitted in the case. A plurality of friction members is fixed to a mobile-device-facing surface of the case bottom so that the friction members contact a bottom of the mobile electronic device when the mobile electronic device is fitted in the case. A plurality of raised corner sidewalls is also provided, each sidewall arranged at a corner of the main chassis to extend in a mobile-device-facing direction from the mobile-device-facing surface of the bottom of the case.

Abstract: Disclosed are a system comprising a computer-readable storage medium storing at least one program, and a computer-implemented method for providing partial views of event streams over a network. A subscription manager receives subscription data from a client device. A messaging interface module receives an event stream comprising event messages. A normalizer converts the received event stream to a table of entries. The entries correspond to respective event messages. A view processor selects a portion of the converted first event stream based at least on the entries of the selected portion of the event stream matching the subscription data. The view processor provides the selected portion of the converted event stream for transmission as session data to the subscriber.

Abstract: A streaming media system employs dynamic rate adaptation. The method includes a file format compatible with legacy HTTP infrastructure to deliver media over a persistent connection. The method further includes the ability for legacy client media players to dynamically change the encoded delivery rate of the media over a persistent connection. The method provided works transparently with standard HTTP servers, requiring no modification and leverages standard media players embedded in mobile devices for seamless media delivery over wireless networks with high bandwidth fluctuations. A system is also specified for implementing a client and server in accordance with the method.

Abstract: An attachable computer includes a frame-structured case; a connector connecting the frame-structured case to a monitor; and a circuit board, a memory device, a microprocessor, and input and output ports provided in the frame-structured case. The memory device, the microprocessor, and the input and output ports are connected with the circuit board in electrical signal communication. The attachable computer can be attached to the monitor to form a one-piece computer. This can effectively utilize existing monitors and reduce electronic waste.

Abstract: A software-defined media platform having one or more media processing units that may be dynamically instantiated, interconnected and configured according to changes in demand, resource availability, and other parameters affecting system performance relative to demand. In one example media processing method, a source media stream may be received via multicast or unicast. The source media stream may be processed into one or more levels of work product segments having different media characteristics by a plurality of transcoding processing units, as needed. One or more levels of work product segments, or the source media stream, may be packaged (e.g., including resegmenting) into final work product segments having select media characteristics, which may be uploaded to a cloud storage unit for delivery to end users.
