  • Patent number: 7894516
    Abstract: A method for equalizing a digital signal received via at least one communication channel is described, wherein a block of received signal values is processed by a block-iterative equalizer (200). The equalizer comprises a feedback unit (202) and a feed-forward unit (201) each corresponding to the multiplication by a respective matrix. The matrices are updated in the iterative process.

  • Patent number: 7876384
    Abstract: A rear projection imaging system with an image warping distortion correction system using a camera and processing unit to generate a warping map that corrects for image distortion. The warping map is generated in an iterative process by displaying a known pattern on a viewing screen and, through the use of a camera, having a microprocessor determine the location and shape of the pattern on the screen. The microprocessor then compares the displayed image to the original reference image, calculates the distortion effects present in the projection optics, and generates a warping map.

  • Patent number: 7876821
    Abstract: A method for rate control for encoding video sequence, wherein the video sequence includes a plurality of Group Of Pictures, wherein each Group of Picture includes at least and I-frame and an Inter-frame, where the rate control method includes the following steps for the encoding of the Inter-frame in the Group of Picture: determining a desired frame rate based on an available bandwidth of a channel for transmitting the video sequence and an available computational resources for the encoding process; determining a target buffer level based on the desired frame rate and the position of the Inter-frame with respect to the I-frame; and determining a target bit rate based on the target buffer level and the available channel bandwidth, wherein the target bit rate is used for controlling the rate of encoding the video sequence.

  • Patent number: 7846112
    Abstract: A compression belt cartridge for use with chest compression devices. The compression belt cartridge has a double-oar shaped belt and a cover plate through which the belt is threaded. The cover plate is provided with hooks and snap latches that fit into a belt drive platform. The cover plate is sized and dimensioned to fit within only selected platforms. The belt attaches to the means for tightening the belt via a spline attached to the belt. The means for tightening a belt then repetitively tightens the belt, thereby accomplishing chest compressions.

  • Patent number: 7840261
    Abstract: A catheter system suitable for implanting pacemaker leads. A guide catheter is provided with steering capability, and the necessary steering components are modified to permit the catheter to be sliced during withdrawal, so that the proximal forced applied to the pacemaker lead is minimized and the lead is less likely to be dislodged.

  • Patent number: 7824356
    Abstract: A system is disclosed for removing gas bubbles from blood during circulatory assist procedures. Such bubbles are generated, along with particulate matter, in an extracorporeal circulatory bypass system by the pump, oxygenator and other components. Filters are used in the line to remove particulates and bubbles from the blood before they are pumped back to the patient but current filters are inefficient at removing small bubbles and debris that can cause neurological defects and renal and other organ failures in the patient. An active filter apparatus and method is disclosed that forces the bubbles to the center of the system where they are removed from the blood before the blood exits the filter. The filter comprises an axially elongate cylindrical shell with a blood inlet, a blood outlet and a gas outlet.

  • Patent number: 7797907
    Abstract: A lateral force resisting system according to the present disclosure includes a metal lateral force resisting panel and holdowns. A foundation bolt placement template may be used to locate and support the foundation bolts during fabrication of the foundation and to further secure the frame foundation interface. The metal lateral force resisting panel may be formed from a single piece of material and may include a plurality of ductility apertures forming lateral force resisting elements to enable the panel to flex without catastrophic failure. In a hybrid configuration, a wooden structural frame may be combined with the metal structural panel. The structural panel may be subdivided into multiple panes using ductility apertures to tailor the response of the panel to the lateral force load. The holdowns secure the rigid structural panel to the foundation bolts and may be either a folded strap and pin configuration or self-tightening.

  • Patent number: 7767080
    Abstract: A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.
