Abstract: A method and a computer-readable medium containing computer program for encoding a frame of video data are presented. The frame of video data has a plurality of macro-blocks. Each of the macro-blocks includes a macro-block header having multiple elements and macro-block residue data. An element of the macro-block header is encoded based on the value of the same element of a previous macro-block header so as to reduce overall bits in the macro-block header. The element of the macro-block header is encoded by grouping the elements of the plurality of the macro-blocks.

Abstract: A mobile device facilitates customized services for its user. For example, a mobile device can record information about a user using multiple inputs (e.g., sensors, GPS, camera, etc.). The information recorded creates a log of activities and interests of the user. One or more parts of the log are published and the user receives additional information based on the published information, such as other nearby people with similar interests or coupons. Other services of the mobile device can include biometric (e.g., facial) recognition of people, voting/polling, and language translation. The services available on a mobile device can be pre-configured so that the user can use the various services out of the box.

Abstract: System and methodologies are provided herein for joint rate, precoder, and feedback design adaptation and optimization for wireless communication systems. An optimization component as provided herein can implement an integrated framework for joint design of rate, preceding, and feedback partitioning adaptation policies for slow fading and spatially correlated multiple-input multiple-output (MIMO) communication channels with limited feedback. The optimization component can utilize one or more vector quantization (VQ) optimization techniques wherein a feedback strategy and a transmission adaptation strategy are designed to jointly optimize average system goodput (e.g., average bits/second/Hz successfully delivered to a receiver) based on spatial correlation of the communication channels. In one example, a feedback strategy is designed as a channel state information of receiver (CSIR) partition and a transmission adaptation strategy is designed as rate and precoder codebooks.

Abstract: An exponential charge pump uses a number of identical or similar charging stages, each having a first and second capacitor. During a first clock phase, the first capacitor of each stage is charged by the second capacitor of the preceding stage, and, during a complementary second clock phase, the positive plate of the first capacitor of each stage is pushed to an increased voltage by the first capacitor of the preceding stage and charges the second capacitor of the next stage to the increased voltage at the same time. A similar mechanism occurs to the second capacitors in each stage, but with complementary timing. The increased voltage of the first capacitor of the last stage is pumped to an output capacitor during the second clock phase, and the increased voltage of the second capacitor of the last stage is pumped to an output capacitor during the first clock phase.

Abstract: The present invention relates to an RFID Tag and Antenna for use with an RFID tag and a method of radio frequency identification (RFID). The RFID Tag comprises a RFID chip 5 for storing data, an antenna 6 and an electromagnetic band gap substrate 12. The RFID chip 5 and the antenna 6 are mounted above the electromagnetic band gap substrate 12. The electromagnetic band gap substrate has a reflection phase which is different from 180° at the operation frequency of the antenna. The electromagnetic band gap substrate enables the RFID to operate even if it is mounted on a conductive object, as the reflection phase is not 180° so it does not destructively interfere with the radiation from the antenna at the operating frequency. Preferably the reflection phase is between 340° and 115° or ?95° and 145°. The preferred embodiment uses a band gap substrate having two mushroom-like conductive layers 3, 7 with a dielectric in between.

The pulsed laser is preferably a solid-state laser such as a Nd-Yag laser. One harmonic is chosen such that it is preferentially absorbed by defects in the polycrystalline silicon layer, the other harmonic is absorbed by the bulk polycrystalline silicon.

Abstract: This invention relates to methods for preparing photo-patterned mono- or polychromatic, polarizing films. The polarizer can be pixelated into a number of small regions wherein some of the regions have one orientation of the principal neutral or color absorbing axis; and some other of the said regions have another orientation of the principal neutral or color absorbing axis. The axis orientation is determined by the polarization vector of actinic radiation and the multi-axes orientation is possible by a separated masked exposure. This polarizer can be placed on the interior substrate surface of the LCD cell.
