  • Publication number: 20090212939
    Abstract: Improvements in a portable hand-held radio frequency wireless remote control are disclosed. The dockable wireless remote control satisfies the need for a low cost compact portable remote control and can advantageously perform additional functions not performed by previous portable wireless remote control units. It can be carried by the user and used like a conventional remote control. It also enables software control of remote devices when connected (docked) to a computer by way of a direct electrical I/O connection. The proposed remote control provides a means to expand the capabilities of portable compact radio frequency wireless remote controls when needed for advanced control functions without significantly compromising their small size or low cost.

  • Patent number: 5581458
    Abstract: A buffered computer data storage tape controller having a microprocessor, a buffer memory, a host interface, an error correction circuit, and a tape drive interface. A host interface control program executed by the microprocessor controls the host interface for transferring computer data between the buffer memory and a host computer, and for receiving commands from the host computer. An error correction circuit control program executed by the microprocessor controls the error correction circuit for generating parity information for computer data stored in the buffer memory and to be written to tape, and for providing error correction for computer data storage read from tape and stored in the buffer memory for transfer to the host computer. A tape interface control program executed by the microprocessor controls the tape drive interface for transferring computer data between the buffer memory and a tape drive.

  • Patent number: 5381292
    Abstract: A method for monitoring the performance of a DAT drive and a method for self-cleaning the tape heads of a DAT drive pursuant to the occurrence of an error that could not be corrected by re-reads or re-writes. The monitoring method includes the steps of (a) reading a tape, (b) determining for each of successive groups of frames respective A track and B track reference error counts representative of the A track and B track C1 error counts in each group of frames, each group having the same number of frames, and (c) providing a warning signal indicative of degraded performance if (i) either the A track reference counts for a predetermined number of consecutive frame groups exceed a predetermined threshold or the B track reference counts for a predetermined number of consecutive frame groups exceed a predetermined threshold, or (ii) if both the A track and B track reference counts for the predetermined number of consecutive frame groups exceed the predetermined threshold.

  • Patent number: 5310669
    Abstract: Substrates having a surface coated with fullerene and a substance attached thereto are disclosed. Cell culture substrates having a fullerene-coated surface are useful in methods of growing cells on the fullerene-coated surface. Methods of preparing cell culture substrates for cell attachment and growth by coating a surface with fullerene are provided. Cells can be grown on a fullerene-coated surface in the presence of a substance such as a cytokine, growth hormone or a drug, to evaluate the interaction between the substance and the cells. Methods for increasing cell membrane premability and for introducing a substance, such as a DNA or RNA vector, into a cell are also provided.

  • Patent number: 5218487
    Abstract: A computer storage DAT drive which detects the form of a DAT tape and provides an audio signal output in response to an audio DAT tape. The drive rewinds the tape and then plays the tape at a speed that is about 5 to 15 times normal playback speed. During such playback, the tape length is determined and the subcode information is read to determine the format of the tape being played back. If the subcode tape format information reliably indicates the presence of an audio tape, the speed of playback is reduced to normal playback, and audio data interface circuitry is enabled for processing the audio data and providing an audio output signal to a front panel audio jack, for example. If the tape is not recognized as an audio tape within the playback of a predetermined length of tape, playback speed is reduced to normal playback speed and reading of the subcode information continues.

  • Patent number: 5163136
    Abstract: Apparatus and method for assembling data read from a data storage DAT tape into data groups. A tape data processing circuit responsive to the playback of DAT tape for provides for each frame a serial frame information output including a frame header and frame data, and an associated subcode information output, the subcode information output being available in advance of the associated frame information. A processor responsive to the subcode information checks the validity of the subcode information and determines the destination group memory locations of the associated frame data, such destination group memory locations being group frame locations specified pursuant to valid subcode information or temporary storage areas for frames having invalid subcode information. DMA circuitry transfers the frame data to the destination group memory locations.

  • Patent number: 5101311
    Abstract: A technique for protecting the tape and mechanism of a DAT tape drive that includes engaging a PAUSE mode of operation, wherein the reel motors are off and the tape is stationarily positioned at a predetermined location, when the drive is not able to record or read a data group. If the amount of time during which the PAUSE mode is engaged exceeds a predetermined PAUSE mode limit, a STOP mode of operation, wherein the reel motors remain off and the pinch roller is disengaged from the tape and capstan, is engaged. If the amount of time during which the STOP mode is engaged exceeds a predetermined STOP mode limit, the tape is unloaded.
