  • Patent number: 6220513
    Abstract: A system for synchronization of the angular position of a rotating optical assembly in a bar code scanner having a rotating optical assembly. The optical assembly is rotated by a motor which produces a fixed number of pulses per rotation, the pulses occurring at equal intervals such that each pulse indicates a degree of angular rotation of the motor. The pulses are continuously monitored and counted. Timing is simultaneously monitored. A synchronization label is placed in the scanner such that light directed through the rotating optical assembly will strike the synchronization label and be reflected back to the rotating optical assembly when the rotating optical assembly is at a particular angular position, thus establishing an initial angular position of the rotating optical assembly. Once the initial angular position is established, timing is continuously monitored and pulses are continuously monitored and counted.

The memory locations include data structures descriptive of control operations to be performed by the scanner control module as well as status to be reported from the scanner to the host system. The low-level control instruction set includes instructions generated by the host system requesting return of particular data from memory locations in the scanner control module as well as instructions requesting the writing of particular data to memory locations in the scanner control module.

  • Patent number: 5988498
    Abstract: A system and method of delaying availability of a price change to checkout terminals following a change in price displayed by an electronic price label (EPL) which minimizes server overhead required to change prices. The method includes the steps of storing a first time associated with the change in price displayed by the EPL, providing a price change file for changing the first price to the second price and containing a delay period, reading the price change file to obtain the delay period, determining whether a current time is later than the first time plus the delay period, and executing the price change file if the current time is later than the first time plus the delay period to replace the first price with the second price.

  • Patent number: 5777307
    Abstract: Each information recording track has pre-formatted fore and rear header sections containing address information identifying the track, which permit each of the recording tracks to be accessed from either of the header sections. A predetermined synchronization signal is pre-formatted in a storing area for each frame having a predetermined data size, so that information can be non-rewritably recorded onto the storing area for a predetermined frame by referring to the pre-formatted synchronization signal. With this arrangement, data can be recorded onto a selected information recording track in either of the directions of relative reciprocating movement of the recording medium to a recording/reproducing head, and thus the recording speed can be increased.

  • Patent number: 5696368
    Abstract: In an optical information recording and reproducing apparatus, information is recorded or reproduced by moving a recording medium relative to an optical head. In order to execute information recording onto the medium in the course of the relative movement involving acceleration and deceleration, the generation timing and intensity of a light beam to be generated in correspondence with the information to be recorded are controlled in response to a varying speed of the relative movement so that data pits to be formed in the recording medium can be standardized in pitch and size irrespective of the relative movement speed. Also, in order to permit information reproduction from the medium in the course of the relative movement involving acceleration and deceleration, reproduction timing of data read by the optical head is set in synchronism with variation in the relative movement speed so that the data can be reproduced at proper timing irrespective of the relative movement speed.
