Abstract: Forward link transmission power to a user terminal in a wireless communications system having a plurality of beams is controlled by determining a baseline power level, Pbaseline, from a received active pilot channel signal-to-noise ratio (SNR); determining a power margin, Pmargin, from an identified interference susceptibility; determining a power level correction, Pcorrection, based on an identified packet error rate (PER); and setting Ptransmit based on Pbaseline, Pmargin, and Pcorrection. For example, Ptransmit may be set to a power level that is substantially equal to the sum of Pbaseline, Pmargin, and Pcorrection. The determination of each of Pbaseline, Pmargin, and Pcorrection may be performed in independently running control loops or processes.

Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: A system and method for quality-based compression utilizing adaptively sized blocks and sub-blocks of discrete cosine transform coefficient data and a quality based quantization scale factor is claimed. A block size assignment element in an encoder element selects the block or sub-block of an input block of pixel data to be processed. Blocks with variances larger than a threshold are subdivided, while blocks with variances smaller than threshold are not subdivided. A transform element transforms the pixel values of the selected blocks into the frequency domain. The frequency domain values are quantized either on a block by block basis or a frame by frame basis utilizing a scale factor that correlates with the quality of the image. The data is then serialized and coded in preparation for transmission.

Abstract: A system and method for automatically calculating safety-related compliance data for vehicle operators. Vehicle operators enter an identification code and status information into a mobile communication terminal located on a vehicle. The identification code and status information is generally stored in a memory located within the mobile communication device. The identification code and status information can be transmitted to a central station where it can be processed to determine compliance with safety regulations. The resulting data may be transmitted back to the vehicle upon request. In another embodiment, a processor located within the mobile communication terminal processes the identification code and status information. The resultant data may then be transmitted to the central station or presented to the vehicle operator upon request.
