The present invention relates to a recording or replay device, and to a method for recognizing a focussing status. The object of the invention is to provide a method of this type and a recording or replay device, with the facility of producing significant astigmatism in the reflected light beam (15) simply and cost-efficiently without elaborate alignment. This object is achieved by the use of a birefringent element (23, 24). The invention is, in particular, suitable for use in a recording or rep...

A video recording and playback device has a control track recorder for recording a control track signal including timing edges recorded on a tape or other storage medium together with the video program. A decoder is coupled to the control track signal and to the tape drive for switching among a forward play mode, a forward skip mode and a rewind mode, as a function of play, skip and rewind codes inserted into the control track as phase variations of edges other than those used for timing, or pre...

The invention provides a method for compacting transactions which have committed at a disconnected client prior to sending the transactions to the server for replaying along with an iterative process for re-calculating the combined transaction in the event that replay at the server fails.

A mailing form having a plurality of fold lines therein to provide a plurality of rectangular panels, a first of said panels containing a cut-out portion which registers upon folding with a space on an adjacent panel provided for addressee information, the entire form in at least partially folded condition adapted for insertion into a window envelope with the addressee space and registered cut-out portion aligned with the window of the envelope. The mailing form also includes a third panel dispo...

A tape recorder particularly for use in language laboratories, with a facility for providing a replay of a short section, such as a phrase up to 15 seconds in length, without reversing the tape. This facility is achieved by providing a play head which is mounted in a spool over which the tape runs and which is adapted to drive against the advance direction of the tape to traverse the head back along the tape. In one form of the invention, the tape is stationary during replay and in a second form...

A processor is provided that includes an execution unit for executing instructions and a replay system for replaying instructions which have not executed properly. The replay system is coupled to the execution unit and includes a checker for determining whether each instruction has executed properly and a plurality of replay queues or replay queue sections coupled to the checker for temporarily storing one or more instructions for replay. In one embodiment, thread-specific replay queue sections ...

A system and method for enabling real-time replay for videogames, wherein the player can selectively rewind the videogame to previously played points in the game in order to replay portions of the game during real-time. Inline keyframes are periodically recorded, together with the controller information, so that upon selecting the replay option, the game can be rewound to the nearest keyframe. Once rewound, the game is restored based on the keyframe and is then played back from the keyframe usin...

A method of writing a spatially heterodyne hologram having spatially heterodyne fringes includes: passing a single write beam through a spatial light modulator that digitally modulates said single write beam; and focusing the single write beam at a focal plane of a lens to impose a holographic diffraction grating pattern on the photorefractive crystal, the holographic diffraction grating pattern including the spatially heterodyne hologram having spatially heterodyne fringes, wherein only said si...

A processor includes a memory execution unit for executing load and store instructions and a replay system for replaying instructions which have not executed properly. The memory execution unit including an invalid store flag that is set for a store instruction if the replay system detects that the store instruction has not executed properly and is cleared if the store instruction has executed properly. If an invalid store flag is set for a store instruction, the replay system replays load instr...

A system for processing a data packet to determine if a replay condition exists for the data packet, wherein the data packet comprises a sequence number for comparison to a highest sequence number. The processing system includes a mask register to store a mask value, wherein the mask value provides an indication of prior receipt by the system of a plurality of data packets, and a shifter comprising an input coupled to receive the mask value from the mask register, wherein the shifter is operable...
