Title: Early rendering for fast channel switching
Inventor: GAO QIANG
IPC: H04N19/895
Filed: 2007-09-19
Abstract: The disclosure relates to techniques for switching between channels of digital multimedia content. In particular, a decoding device decodes and renders to a display at least one frame of a segment of data prior to receiving the entire segment. In certain aspects, the decoding device may render one of the frames of the segment and freeze the rendered frame until the decoding device receives all of the frames of the segment. In other aspects, the decoding device may render frames of one or more segments at a reduced rendering rate until the receiving and rendering operations of decoding device are synchronized such that the rendering of the current segment occurs at substantially the same time as the receiving of the next segment. By rendering at least frame prior to receiving the entire segment the decoding device more quickly displays content to a user during a channel switching event.

Title: Video enhancement and display power management
Inventor: SANKAR ANANTH
IPC: G09G3/36
Filed: 2007-06-30
Abstract: In visual display devices such as LCD devices with backlight illumination, the backlight typically consumes most of device battery power. In the interest of displaying a given pixel pattern at a minimized backlight level, the pattern can be transformed while maintaining image quality, with a transform determined from pixel luminance statistics. Aside from, or in addition to such minimizing, a transform also can be used for image enhancement, for a displayed image better to meet a visual perception quality. In either case, the transform preferably is constrained for enforcing one or several display attributes.

Title: Dynamic slew rate control based on a feedback signal
Inventor: MATHE LENNART K A
IPC: H03M3/02
Filed: 2008-07-15
Abstract: Techniques for enhancing the slew rate of an active circuit within a feedback circuit (such as a ADC) are described. In one design, a ADC includes an integrator, a slew rate enhancement circuit, and a control circuit. The integrator receives an input signal and provides an output signal. The slew rate enhancement circuit enhances the slew rate of the integrator based on a feedback signal in the ADC. The slew rate enhancement circuit may provide (i) a boost current for only certain values (e.g., the largest and smallest values) of the feedback signal or (ii) different amounts of boost current for different values of the feedback signal. In one design, the slew rate enhancement circuit includes at least one boost circuit coupled to the integrator. Each boost circuit provides a boost current to enhance the slew rate of the integrator when that boost circuit is enabled.

Title: Detachable coil incorporating stretch resistance
Inventor: FITZ MATTHEW
IPC: A61B17/00
Filed: 2008-07-28
Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.
