An automatic playback overshoot correction system predicts the position in the program material where the user expects to be when the user stops the fast forward or reverse progression of the program material. The invention determines the position where the program material was stopped. The media controller transitions to the new mode that the user selected, starting at the stopped position with an overshoot correction factor added or subtracted from it. The invention adapts to the user by remembering how much the user corrects after he stops the fast forward or reverse mode. Correction factors are calculated using the user's corrections and adjusting the correction factors if the user continues to make corrections. The invention also uses a prediction method to correctly place the user within the program upon transition out of either mode and determines if the speed of the fast forward or reverse modes and then automatically subtracts or adds, respectively, a time multiple to the frame where the transition was detected and positions the user at the correct frame. The time multiple is fine tuned if the user is consistently correcting after the fast forward or rewind mode stops. Another method initially tests the user's reaction time using a test video and asks the user to press the fast forward or reverse button on his control device during the test video and then asks the user to position the video to the place that he expected the system to have been. This time span is then used whenever the user uses the fast forward or reverse modes and is adjusted with a multiple for each speed. A final method allows the user to simply set a sensitivity setting that the system will use as a correction factor and a multiple is subtracted or added to the release frame whenever the user uses the fast forward or reverse modes, respectively.

Non-volatile memory devices and arrays are described that utilize reverse mode non-volatile memory cells that have band engineered gate-stacks and nano-crystal charge trapping in EEPROM and block erasable memory devices, such as Flash memory devices. Embodiments of the present invention allow a reverse mode gate-insulator stack memory cell that utilizes the control gate for programming and erasure through a band engineered crested tunnel barrier. Charge retention is enhanced by utilization of high work function nano-crystals in a non-conductive trapping layer and a high K dielectric charge blocking layer. The band-gap engineered gate-stack with symmetric or asymmetric crested barrier tunnel layers of the non-volatile memory cells of embodiments of the present invention allow for low voltage tunneling programming and erase with electrons and holes, while maintaining high charge blocking barriers and deep carrier trapping sites for good charge retention.

The present invention relates to an improved countermeasure for circadian and sleep disruption as caused by a traditional alarm clock. It incorporates a lighting system at the alarm clock that, prior to the preset waking time, will emit a light that gradually increases in intensity as it changes the ultraviolet spectrum of light it emits, so as to simulate the rising sun. This will ease the waking process for many people, especially those prone to simple disruptions of their circadian regulation. It may also be set to operate in a reverse mode so as to simulate the setting sun thus helping stimulate melatonin production and easing one into sleep.

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.
