Title: Continuous cipher synchronization for cellular communication system
Inventor: DENT PAUL W
IPC: H04L9/12
Filed: 1991-03-06
Abstract: A system for the synchronization of encryption devices in a digital cellular communications system. Each of the encryption devices includes a multi-bit counter and generates a pseudo-random keystream which is combined with the data to be encrypted. The keystream is a function of the multi-bit counter value which is periodically incremented in response to a series of clock pulses. To allow proper decryption of the encrypted data, the system of the present invention provides continuous or very frequent updates of the transmitter counter value which may be used to reset the receiver counter and to resynchronize the system without the necessity of reinitialization and repetition of the intervening clock pulses.

Filed: 1991-11-21
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a method for quantitatively assaying the presence of DSP toxins such as okadaic acid and dinophysistoxin-1 in marine samples.  The method comprises the steps of preparing a marine extract, fractionating the prepared marine extract and selecting the extract fraction containing the toxin to be assayed. Once the desired extract fraction has been selected, a labelled substrate for protein phosphatase and at least one protein phosphatase are added to the extract in an assay.  The amount of toxin present is quantitatively measured by the ability of the extract fraction to inhibit catalysis, mainly dephosphorylation, of the labelled substrate by protein phosphatases, such as phosphatase-1 (PP1) or phosphatase-2A (PP2A).  Preferably, the method of the present invention is used to assay the presence of okadaic acid in marine organisms such as mussels, oysters, scallops, phytoplankton and the like.

Title: System for recording and reproducing a wide bandwidth video signal via a narrow bandwidth medium
Inventor: PATEL CHANDRAKANT B
IPC: H04N5/917
Filed: 1991-12-02
Abstract: An  encoder  processes  a  composite  video  signal including luminance and chrominance components into a folded limited bandwidth video signal including a low frequency  luminance  band component having  a  limited bandwidth and a high frequency luminance band component adaptively de-emphasized in amplitude and folded into the spectrum of the low frequency luminance band, along with a   chrominance-plus-motion   signal   containing   the chrominance component having encoded thereon a motion signal derived from and representative of image motion in the input video signal, and suitable for transmission or recording via a  limited bandwidth video medium and compatibly reproducible by narrow bandwidth reproduction devices due to the de-emphasized folded high luminance band and encoding  of the motion signal onto vacant portions  of  the  chrominance  component.   A  decoder converts the encoded signal into an unfolded wideband video  signal  including  a  baseband  luminance  signal containing the low band luminance component along with the unfolded high band luminance component re-emphasized to its original amplitude, together with the chrominance component signal separated from the encoded composite chrominance-plus-motion signal, whereby a full bandwidth image may be displayed.  The motion signal is utilized in the encoder for motion-adaptively pre-filtering the input luminance and is recovered in the decoder for motion-adaptively post-filtering the unfolded luminance.  The system can be applied to a narrowband VCR such as a VHS format VCR for providing improved resolution images on implementing playback devices with backward compatibility on conventional playback devices.

IPC: G11B23/087
Filed: 1992-02-27
Abstract: ABSTRACT    A pair of spaced reel springs are integrally molded on a cassette cover to extend inwardly and downwardly at an angle.   When the cassette cover and base are mated,  the springs bias movable tape reels against the cassette base.          A removable dust door includes an extension having a pair of integrally formed projections.   The projections extend, when the removable dust door is positioned on the cassette, into openings formed in the tape cassette around the reel springs.          The projections abut the springs, hold the tape reels against the cassette base and relieve the load from the springs.
