  • Patent number: 9432674
    Abstract: Multi-level prediction mode encoding type decision methods and systems are presented. In one embodiment, an indication of a prediction mode level is received and encoding is performed in accordance with said prediction mode level. The indication of said prediction mode level is programmable and can be set at different levels. The prediction mode level can be associated with a programmable encoding type decision point (e.g., early, intermediate, late, etc.). The encoding process includes deciding upon an I-type or P-type encoding. In one embodiment, a multi-stage encoding type method is also implemented in intra-prediction related search and inter-prediction related search and respective corresponding prediction operations are performed, wherein at least a portion of the intra-prediction related search and the inter-prediction related search are performed in parallel.

  • Patent number: 8761253
    Abstract: The following embodiments describe an approach for selecting an intra prediction mode for video encoding, such as occurs in the H.264 standard. One embodiment describes a method of selecting an optimum intra prediction mode. This method involves selecting a first intra prediction mode, which is used to determine a search order for a number of intra prediction modes. These intra prediction modes are then evaluated in order to identify the optimum intra prediction mode.

  • Patent number: 7453066
    Abstract: Gamma radiation events are received individually at elements of a detector array (18) at least one of the elements (P0) being defective. Each detector element converts incident radiation into a radiation event signal which is digitized by an analog-to-digital converter (42) into a coordinate position (x,y) on the detector array and energy (z). An event generator (48) generates radiation event signals for each defective element based on radiation events received at contributing elements, e.g., nearest neighbor elements (P1-P8). In a preferred embodiment, the contribution from each of the contributing elements is randomized by passing a token (56) among positions of a table (54) corresponding to each of the contributing elements. Each time a radiation event is received at the contributing element whose corresponding table position holds the token, that event also generates an event signal for the defective element and the token is passed (58).

  • Publication number: 20050263030
    Abstract: A cart system designed for usage in attics and crawl spaces. The system utilizes a platform of previously-determined length, at least one track upon the platform, and a cushioned and wheeled seat component upon the track. In the preferred mode, the device is powered, utilizing an electric motor with chain drive assembly. When the motor is engaged via manual switch or remote control, the motor activates the chain drive assembly to move the seat along the track at a slow pace, forwardly, backwardly, or on turns. In the preferred mode of production, the system also includes sensors which function to stop the seat portion should the same move too close to an end of the platform. Alternatively, the system may be manually powered, such as through usage of pulleys or the like. The platform may be of any length suitable to adequately cover the length of an attic or crawl space.

  • Patent number: 6789274
    Abstract: An enhanced chest protector for usage in sporting events and hazardous activities. More particularly, the invention is a chest protector that utilizes a soft, pliable gel attached to the previously-existing chest protector to greatly enhance absorption and dissipation of impact forces. The gel is of a type commonly used for heat or freezer packs, and is configured in many separate panels to keep the gel from flowing across the entire device. Importantly, the gel is durable and lightweight, which allows the player to wear the product comfortably for extended periods of time. In addition, the gel may be frozen or refrigerated prior to use, so as to provide cooling for the player in hot water.

  • Publication number: 20030019896
    Abstract: A belt-mounted holder for spackle items. More particularly, the invention is an item that is removably attachable to a belt of a user, and functions to hold a hawk or spackle device so that the user does not have to put the item down while working. The holder is preferably constructed of simple metals or plastics, and consists of two main panels that are hingedly attached. A generally vertical panel is affixed to the user's belt area and stays against the user's body. The second panel folds down from the first panel to a position parallel to the ground. The panel folds and stays in such a position through usage of a spring loaded mechanism. Located on the second panel is a hole of sufficient diameter to receive the handle portion of the hawk.
