Abstract: In a digital motion picture camera comprising an electronic image sensor for generating image signals, a control unit is configured, in response to a scene record command, to generate a sequence data stream, which represents a sequence of consecutive frames, from the image signals of the image sensor and to transmit the sequence data stream to a sequence memory device. The control unit is configured, in response to an identification image record command, to generate an identification image data set, which represents at least one scene identification image, from the image signals of the image sensor and to buffer the identification image data set in a buffer memory, with the control unit further being configured to insert the buffered identification image data set into a subsequently generated sequence data stream such that the sequence of consecutive frames is preceded by the scene identification image.

Abstract: A flexible sleeve includes a first flexible sheet of a first hardness. The first flexible sheet has a first perimeter including a first lip edge and a first pocket edge. The flexible sleeve also includes a second flexible sheet of a second hardness, different than the first hardness. The second flexible sheet has a second perimeter including a second lip edge and a second pocket edge. The second pocket edge is joined to the first pocket edge, and the second lip edge is free from the first lip edge so that the first flexible sheet and the second flexible sheet collectively form a pocket having a mouth defined by the first lip edge and the second lip edge. The flexible sleeve further includes a connector joined to the mouth and configured to mate the mouth to a head of a device while the pocket substantially covers a tail of the device.

Abstract: Provided herein are methods and systems that provide automatic compensation for frequency attenuation of a video signal transmitted over a cable. In accordance with an embodiment, a system includes an equalizer and a compensation controller. The equalizer receives a video signal that was transmitted over a cable, provides compensation for frequency attenuation that occurred during the transmission over the cable, and outputs a compensated video signal. The compensation controller automatically adjusts the compensation provided by the equalizer based on comparisons of one or more portions of the compensated video signal to one or more reference voltage levels. The compensating is selectively locked and reset in response to specific conditions being detected, e.g., a locking condition and a reset condition.

Abstract: A computer mouse includes a head and a tail. The head is configured to detect movement relative to a reference surface. The head is selectively switchable between an on state and an off state. The tail is connected to the head and is moveable between a curved configuration and a flat configuration. The tail is configured to switch the head to the on state when in the curved configuration and to switch the head to the off state when in the flat configuration.

Abstract: Mechanical architecture for providing maximum viewing area on key button tops of keys for a user input device. The viewing area is for the display of information on the key buttons, and also includes tactile feedback similar to standard laptop keyboards, all using low cost manufacturing methods such as injection molding. The architecture optimizes an aperture through the core of the key switch assembly in order to project an image through the aperture and onto the display area of the key button. The architecture relocates in at least one embodiment the tactile feedback mechanism (e.g., dome assembly) out from underneath the key button to the perimeter or side of the key switch assembly. The architecture finds particular application to input devices such as keyboards, game pods, data entry device, etc., that operate in combination with an optical surface (e.g., wedge lens).

In accordance with an embodiment of the present invention, the output stage of the present invention includes a translinear current controller, an output transistor and a current mirror. While not limited thereto, embodiments of the present invention only require a single positive power supply, consistent with the recent trend toward integrated circuits that only require a single low voltage power supply.

Abstract: Provided herein are self-calibrating timing circuits and methods for use in a sync separator. A comparator compares a video signal to a video reference voltage to produce a sliced sync signal that has a frequency that is equal to a scan frequency of a horizontal sync embedded in the video signal. A first converter converts the sliced sync signal to a control signal having an amplitude or magnitude that is inversely proportional to the scan period of the horizontal sync embedded the video signal. A second converter converts the voltage control signal to a timer signal that has timed intervals that are that are inversely proportional to the amplitude or magnitude of the control signal, and thus proportional to the scan period of the horizontal sync embedded in the video signal. These timed intervals produced in accordance with embodiments of the present invention are easily and precisely scalable, allowing them to be used to discriminate various timing features embedded in video signals.
