Title: Aid for inducing sleep or the like utilizing light
Inventor: MASUDA ISAMU
IPC: A61M21/02
Filed: 1991-07-29
Abstract: A B S T R A C T   The present invention relates to an aid for inducing sleep or the like which induces a person to a state such as sleep, meditation utilizing light. This inducing aid 1 is configurated in a manner that light emitting bodies 9, 10, 11 and 12 are disposed respectively at the both side and the top and bottom positions of the positions of both eyes of a bandage around centers 14a and 14b thereof. The conventional inducing aid has a configuration wherein one light emitting body is disposed at each of the positions of both eyes, and therefore each lightemitting body often deviates from the eye position due to variation in the interval between the right and left eyes, and the effect thereof is reduced by half. On  the contrary, in accordance with  the inducing aid of the present invention, any of the light emitting bodies at the both-side positions and the top and bottom positions corresponds to each of the positions of both eyes, and therefore a desired inducing effect is obtained reliably.                             <6>

Title: Geometric vector quantization
Inventor: JACQUIN ARNAUD E
IPC: H04N19/94
Filed: 1993-01-25
Abstract: A geometric vector quantizer coding technique is illustrated in the context of a full motion video coder based on a three-dimensional sub-band framework. The original image data is decomposed into different spatial-temporalfrequency bands and based on the data in each band, different quantization strategies are applied to the bands. The lowest spatial-temporal frequency band is coded using a traditional three-dimensional switched predictor and optimum scaler quantizer.The non-dominant sub-bands are coded using the vector quantization approach to efficiently encode the images while appropriately exploiting the sparse, highly structured nature of the data to design the codebooks. Variable resolution is achieved using these techniques and no training is needed to establish or maintain the codebook. A fast codebook search technique is provided for identifying the optimal codebook vector for representing a block of input data. Examples of two and three level geometric vector quantizers are also provided.

Patent CA-2092253-A1 (CA)
Inventor: SCHMODE HARTMUT
IPC: H01R43/045
Filed: 1993-03-23
Abstract: The invention relates to pliers for dressing conductor ends, having a pair of handles, moveable relative to one another, a plurality of dressing stations for the conductor ends, and having a drive device via which the dressing stations can be driven during operation of the handles. One of the dressing stations is constructed as a crimping drum which can be displaced axially, and is supported such that it can rotate, can be coupled to the drive device in the axially displaced position over only one dressing process, and, in this position, can be locked via a flange which projects radially from it.  This flange extends over the overall circumference of the crimping drum and has at least one recess.  A locking tab, which is arranged in a fixed position on the body of the pliers and is radially opposite the flange,  engages,  in the undisplaced axial position of the crimping drum,  into the recess, to be precise up to a point close to the outer surface of the crimping drum while, in the axially displaced and rotated position of the crimping drum, the locking tab comes to rest above the outer surface of said crimping drum and engages behind the flange.  Locking of the crimping drum both  in  the  rotational  direction  and  in  the  axial displacement direction is thus possible by means of the locking tab.

Title: Spectrum recovery apparatus and method therefor
Inventor: VATT GREGORY B
IPC: H04B7/185
Filed: 1993-03-26
Abstract: A controller operates with a cellular communication system that transmits primary communications. The controller recovers a portion of the spectrum assigned to the primary communications for reuse in transmitting secondary communications. The primary communications' cells move in a predictable manner relative to a site at which the controller is located. The controller monitors primary communications to determine the current active cell.      The identities of past active cells are saved so that a historical sequence of active cells is available. A map defining the relative orientation of cells is used with the historical sequence information to predict tracks through newly entered active cells. Based on this prediction, a recoverable cell is selected.      Communication link parameters of the recoverable cell are used for secondary communications. The identity of the recoverable cell changes in response to changes in the identity of the active cell.

Title: Method and apparatus for discriminating among normal and pathological tachyarrhythmias
Inventor: DUFFIN EDWIN G
IPC: A61N1/362
Filed: 1991-11-07
Abstract: Far-field ventricular and (optionally) atrial electrograms of a suspect tachyarrhythmia are compared against stored morphologies of one or more control rhythms to allow discrimination between normal and pathologic tachyarrhythmias. The existence of a run of tachycardia is determined by an algorithm which compares the near-field atrial and ventricular electrograms against tachyarrhythmia rate thresholds and (optionally) rate acceleration, rate stability and/or sustained high rate criteria. When elevated rates are detected employing the near-field electrograms, far-field atrial electrograms are obtained by sensing between one of the bipolar electrodes in the ventricle and a remote indifferent electrode, typically on the pulse generator or at a location along the lead catheter but outside of the atrium. Similarly, far-field ventricular electrograms are obtained by sensing between one of the bipolar atrial electrodes and a remote indifferent electrode.
