Abstract: A Hybrid Automatic Retransmission Request (H-ARQ) technique is provided for Multi-Input Multi-Output (MIMO) systems. The technique changes the basis (V) upon retransmission, which helps reduce the error probability upon retransmission. This basis hopping technique provides for improved performance gain without significant increase in design complexity. In one embodiment, communication device (100) includes a receiver section (114) for receiving an acknowledgment (ACK) or a non-acknowledgment (NACK) signal in response to information transmitted by the transmitter section of the communication device. If a NACK is received, a new basis is selected from a set of basis stored in a basis set unit (110). The new basis that is selected is then used by a linear transformation unit (106) in the retransmission of the information.

Abstract: A vertical blanking interval (VBI) signal testing tool captures, isolates, and analyzes a VBI signal to determine the quality of the VBI signal or signal source. A digitized VBI signal is received and analyzed according to industry standards. The VBI signal is first examined using thresholds, threshold points, and other points as a way of discerning waveforms in the signal and their individual characteristics. Thereafter, deviations of the VBI signal from industry standards are logged or displayed for review.

Abstract: This invention integrates functionality to prior-art meeting system infrastructures that cannot be achieved by existing designs. The system allows for the creation of a meeting enabling multiple end user device combinations of varying compatibility—each device containing multiple different peripherals—to seamlessly two-way communicate and manage incoming and outgoing communications. An advantage is the ability to translate any feed data into a device compatible format. The invention enables end user context-independent subscription to an arbitrary number of data feeds originating from an arbitrary number of connected end users. Finally, the invention defines a meeting replay system using the invention infrastructure that has the ability to record any combinations of data feeds from any combinations of end users and replay any part of the meeting through the same invention-infrastructure.

Abstract: A component, such as a Component Object Model (COM) object, operates as an intermediary between an Application Programming Interface (API) extension or plug-in and a driver. The component allows additional objects to be aggregated onto the component, and/or sets one or more setting values for a received request so that an I/O call associated with the request can be completed in a manner that is compatible with other I/O calls. The component may also return, in response to a particular request, a stream index associated with the component.

Abstract: System and method for preserving food. Embodiments of the system include a food compartment to store food and a user interface configured to receive user input relating to the preservation of the food stored. The system also includes a humidity sensor configured to sense a humidity level, an ozone generator configured to generate ozone gas, an ozone sensor configured to sense an ozone level and a gas sensor configured to sense a level of residual gases inside the food compartment. The system further includes a controller, responsive to the user interface, the humidity sensor, the ozone sensor and the gas sensor. In one embodiment, the controller preserves the food stored in the food compartment as a function of the user input, the humidity level, the ozone level, the residual gas level and as a function of a type of the food stored in the food compartment.

Abstract: An air treatment system includes a housing defining a chamber, and an ultraviolet lamp positioned within the chamber. The housing further defines an air inlet at a first end portion of the housing and an air outlet at a second end portion of the housing opposing the first end portion. The chamber provides flow communication between the air inlet and the air outlet. At least one ultraviolet lamp is positioned within the chamber. The at least one ultraviolet lamp is positioned about a first axis and includes a first end and a second end spaced with respect to the first end along the first axis. The at least one ultraviolet lamp is configured for facilitating inactivating contaminants within air channeled through the chamber.

Abstract: A streaming video interface component receives video frames from a streaming driver before the frames are received by a consuming application. The streaming video interface component provides the video frames to a video effect rendering component which renders video effects selected by a user. The video frames with the rendered video effects are then provided back to the streaming interface component which thereafter provides them to the consuming application.

Abstract: A method of transmitting a communication signal (FIG. 1) is disclosed. The method includes receiving a data signal (102). The method further includes receiving a codeword index (pre-coder selection) from a remote transceiver. A codeword is selected from a Householder matrix based codebook in response to the index. The data signal is precoded (104) in response to the selected codeword. The precoded data signal is transmitted (100) to the remote transceiver.

Abstract: A wireless receiver providing multiple services (FIG. 3) is disclosed. The wireless receiver includes an oscillator circuit (304, FIG. 4) arranged to produce a reference frequency (308). A first receiver (302) receives a first signal (300) having a first carrier frequency in response to the reference frequency. A second receiver (322) receives a second signal (320) having a second carrier frequency different from the first carrier frequency in response to the reference frequency.

Abstract: A method and apparatus are provided that uses the feedback information from an ARQ signal that is received to control the transmit diversity of a transmitter. The method provides for improved performance over some existing ARQ plus open loop transmit diversity schemes in terms of bit-error rate for a given Eb/No. Furthermore, the method does not require extra signaling used by closed loop TD schemes.

Abstract: A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

The cooling source provides a separate controllable temperature to the chiller compartment, which is adapted to be removably positioned in a selected temperature controlled environment. In another aspect a refrigerator comprises a freezer unit, a fresh food unit and a chiller compartment adapted to be removably positioned in either the freezer unit or the fresh food unit as a secondary chilling compartment. In another aspect a method of chilling comprises cooling a modular chiller compartment using an independent cooling source, chiller compartment being removably positioned within a temperature controlled environment and the cooling source and the chiller compartment being thermally coupled.

Abstract: A vertical blanking interval (VBI) signal testing tool captures, isolates, and analyzes a VBI signal to determine the quality of the VBI signal or signal source. A digitized VBI signal may be received and analyzed according to industry standards. The VBI signal is examined using thresholds, threshold points, and other points as a way of discerning waveforms in the signal and their individual characteristics. Thereafter, deviations of the VBI signal from industry standards are logged or displayed for review. One feature of the tool records captured VBI data to a persistent storage medium, thereby allowing post-processing of the VBI signal at another time and/or another location. An exemplary analysis program can read the recorded VBI data from the persistent storage medium and perform tests to determine the quality of the VBI signal or signal source. VBI signal translations are also contemplated.
