A prediction method, merged method, has been introduced in the enhancement layer of a multiple layer video coding. This merged method was designed to efficiently handle the prediction of the non moving parts in coding of the enhancement layer VOP or frame. All the information for this merged mode prediction is obtained from the base layer, and no additional side information is transmitted. This prediction mode when used together with combination of the existing forward mode, backward mode, and interpolated mode, can improve the coding efficiency for enhancement layer video coding, especially in low bit rate coding. The method can be used in most multiple layer video coding schemes, especially in spatial scalability video coding.

A non-linear dynamic predictive device (60) is disclosed which operates either in a configuration mode or in one of three runtime modes: prediction mode, horizon mode, or reverse horizon mode. An external device controller (50) sets the mode and determines the data source and the frequency of data. In prediction mode, the input data are such as might be received from a distributed control system (DCS) (10) as found in a manufacturing process; the device controller ensures that a contiguous stream of data from the DCS is provided to the predictive device at a synchronous discrete base sample time. In prediction mode, the device controller operates the predictive device once per base sample time and receives the output from the predictive device through path (14). In horizon mode and reverse horizon mode, the device controller operates the predictive device additionally many times during base sample time interval. In horizon mode, additional data is provided through path (52). In reverse horizon mode data is passed in a reverse direction through the device, utilizing information stored during horizon mode, and returned to the device controller through path (66). In the forward modes, the data are passed to a series of preprocessing units (20) which convert each input variable (18) from engineering units to normalized units. Each preprocessing unit feeds a delay unit (22) that time-aligns the input to take into account dead time effects such as pipeline transport delay. The output of each delay unit is passed to a dynamic filter unit (24). Each dynamic filter unit internally utilizes one or more feedback paths that are essential for representing the dynamic information in the process. The filter units themselves are configured into loosely coupled subfilters which are automatically set up during the configuration mode and allow the capability of practical operator override of the automatic configuration settings. The outputs (28) of the dynamic filter units are passed to a non-linear analyzer (26) which outputs a value in normalized units. The output of the analyzer is passed to a post-processing unit (32) that converts the output to engineering units. This output represents a prediction of the output of the modeled process. In reverse horizon mode, a value of 1 is presented at the output of the predictive device and data is passed through the device in a reverse flow to produce a set of outputs (64) at the input of the predictive device. These are returned to the device controller through path (66). The purpose of the reverse horizon mode is to provide essential information for process control and optimization. The precise operation of the predictive device is configured by a set of parameters. that are determined during the configuration mode and stored in a storage device (30). The configuration mode makes use of one or more files of training data (48) collected from the DCS during standard operation of the process, or through structured plant testing. The predictive device is trained in four phases (40, 42, 44, and 46) correspo

The network device may select a forwarding mode based on attributes of the network that are detected or otherwise received by the network device.

The present disclosure provides a power split transmission with two Electric Variable Transmission (EVT) modes and four fixed gears for use in hybrid electrical vehicles (HEV). The present disclosure utilizes two electric motors (“E-motors”), an engine, three planetary gear sets, and four selectively engageable clutches. The clutches are engaged in different combinations to engage the different gears and EVT modes. In the four fixed gears, power is transmitted only on the mechanical path for the highest transmission efficiency. In the two EVT modes, a part of the power is transmitted electrically. Alternatively, the E-motors can be located in the middle integrated with the transmission design. Advantageously, the present invention works with lower component speeds than existing two-mode hybrid transmissions. This can be achieved with a front E-motor design enabling modularity and also with a center E-motor design.

A PC card video recorder. The conditional access functionality of a Point Of Deployment module (POD) is augmented by providing solid state memory on a PC card for recording and playback of programming. An encrypted video stream from a television Set-Top Box (STB)or other appliance is decrypted in the PC card. The decrypted video stream is then filtered to remove information not relevant to a program to be stored. The filtered video stream is then applied to the solid state memory. During playback, the video stream is retrieved from the memory and encrypted prior to transmission to the STB. Intra-pictures can be played back rapidly to provide a fast forward mode by reference to a table or packet header storing starting and ending address of the intra-pictures. Multiple POD card interfaces can be provided in the STB to accept multiple PC card recorders. Pairing security can be provided by checking a recording STB identifier against a playback STB identifier.

Some exemplary embodiments of a III-nitride switching device with an emulated diode have been disclosed. One exemplary embodiment comprises a GaN switching device fabricated on a substrate comprising a high threshold GaN transistor coupled across a low threshold GaN transistor, wherein a gate and a source of the low threshold GaN transistor are shorted with an interconnect metal to function as a parallel diode in a reverse mode. The high threshold GaN transistor is configured to provide noise immunity for the GaN switching device when in a forward mode. The high threshold GaN transistor and the low threshold GaN transistor are typically fabricated on the same substrate, and with significantly different thresholds. As a result, the superior switching characteristics of III-nitride devices may be leveraged while retaining the functionality and the monolithic structure of the inherent body diode in traditional silicon FETs.

Replaying a compressed digital video stream in fast-forward and reverse modes at varied playback rates. An index of interceded frames, those frames not dependant on other frames for generation, is stored. The index includes the size of intercoded frames and their storage location. When a specified playback rate is requested, the intercoded frames are retrieved using the index. The interceded frames then have one or more intracoded frames, frames that reference other frames for generation, placed between them to generate a frame sequence. The intracoded frames are “blank,” meaning they contain only information from their associated interceded frame. By inserting “blank” frames specified playback rates and bit rates are generated. The index of interceded frames may also be accessed to generate playback in reverse mode, which conserves memory resources of associated systems by generating the reverse playback stream in an iterative manner.
