Title: Scrambling system for serial digital video
Inventor: HERSHBERGER DAVID L
IPC: H04N7/167
Filed: 1995-12-01
Abstract: A scrambler system that is compatible with SMPTE Standard 259M inserts a detector/dithering circuit (20) between the input serial digital signal and a scrambler (10). The scrambler's statistics are observed by a pair of up/down counters (24, 25). One asymmetric counter (24) monitors the scrambled data prior to NRZI encoding (18, 19) to determine transition density, and the other (25) monitors the NRZI encoder output to determine the relative density of "ones" and "zeros" in the scrambled output signal. A pseudorandom generator (26) generates a dither signal which is combined with the least significant bit of selected video words of the input serial digital signal when enabled by the terminal count (TC) output from either counter. A complementary descrambler Fig. 2, (not shown), has a similar detector/dithering circuit (20') at its output to restore the original least significant bit of the selected video words. The scrambler/descrambler may be implemented also in the parallel domain Fig. 3, 4, (not shown). Thus pathological signals are avoided that could create problems within the serial digital video bit stream. <IMAGE>

Title: Electro-convulsive therapy system
Inventor: SHAW JOHN B
IPC: A61N1/38
Filed: 1996-11-22
Abstract: An electro-convulsive therapy (ECT) system includes both hardware and software safety detectors and monitors, and a pulse generator (56) that generates trains of pulses, with user-specified parameters. Safety detectors detect pulse characteristics including pulse width, frequency, voltage, current, treatment duration, as well as energy. Safety monitors (40, 54) monitor these parameters during treatment to ensure that the system operates according to specification and does not injure the patient. If any safety detectors detect a parameter that is out of tolerance, the safety monitors disable the pulse generator (56) so that no further pulses are delivered to the patient. The system includes a pre-treatment arming routing that applies a pre-treatment ECT pulse train to an internal load and monitors these same parameters to arm or disarm the system. The patient's EEG and ECG may be monitored, and induced convulsions detected with an optical motion sensor on a knuckle.

Title: Glass breakage detector
Inventor: ZHEVELEV BORIS
IPC: G08B13/04
Filed: 1994-12-01
Abstract: Method and apparatus to determine if a sound produced by an event is due to glass breakage comprises producing a plurality of frequency band-limited signals from an electrical signal characteristic of the sensed sound and characterising the event by comparing at least one characteristic value derived from the band-limited signals with a relatively narrow range of values and with a relatively wide range of values. The event is characterised as a glass-breakage event if the value is within the narrow range, as a non-glass breakage event if the value is outside the wide range and as an event to be further analysed, to determine whether glass breakage has occurred, if the value is within the wide range but outside the narrow range. Sound characteristics in three frequency ranges and four time periods, associated with various aspects of glass impact and breakage, are used in the determination and a variety of measurements and comparisons are performed on the band-limited signals, their integrals and derivatives to validate, exclude or further process an event.

Title: Image tracking; observer tracking stereoscopic display
Inventor: HOLLIMAN NICOLAS STEVEN
IPC: G02B30/26
Filed: 1997-04-17
Abstract: An image tracking system 2 comprises a video camera 3 or other device for presenting a sequence of images to a processor 4. The images are presented in real time in the form of a sequence of video fields. The processor 4 determines (79, fig 18) the position of a target image in a preceding image frame, for instance using a template matching technique limited to the region of the image field where the target image may be located. The processor 4 then determines (76, fig 18) the amount of movement between the preceding field and the next field, for instance by using a differential technique. The updated position of the target image is then formed (77, fig 18) as the sum of the position of the target image in the preceding field and the amount of movement between the preceding field and the next consecutive field. The position data are supplied (78, fig 18), for instance, to a window steering mechanism 6 of an autostereoscopic 3D display 7 so that the eyes of an observer 8 can be tracked to ensure autostereoscopic viewing of the display 7 with an enlarged degree of freedom of movement of the observer.

Title: Filtering noise from seismic data
Inventor: OZBEK ALI
IPC: G01V1/36
Filed: 1998-05-20
Abstract: A method relating to filtering coherent noise and interference from seismic data by constrained adaptive beamforming is described using a constraint design methodology which allows the imposition of an arbitrary predesigned quiescent response on the beamformer. The method also makes sure that the beamformer response in selected regions of the frequency-wavenumber space is entirely controlled by this quiescent response, hence ensuring signal preservation and robustness to perturbations. Built-in regularization brings an additional degree of robustness. Seismic signals with arbitrary spectral content in the frequency-wavenumber domain are preserved, while coherent noise and interference that is temporally and spatially nonstationary is adaptively filtered. The approach is applicable to attenuation of all types of coherent noise in seismic data including swell-noise, bulge-wave noise, ground-roll, air wave, seismic vessel and rig interference, etc. It is applicable to both linear or areal arrays.
