Patent CA-2061722-C (CA)
Inventor: ZULLIG KURT
IPC: F16B12/32
Filed: 1992-02-24
Granted: 2002-08-20
Abstract: This clamping device is intended for releasably connecting two profiled parts (1,19). One of the profiled parts (1) is arran-ged so that an insert core (2) can be inserted and fixed in it.      The core (2) has an axially movable bolt (7) having an end portion which comprises a projection (21) intended to be intro-duced in a slot of a second profiled part (19) in order to exert a force against an area of a portion of said second pro-filed part (19) partially covering said opening. A screw recei-ved in a threaded bush (4) engages the bolt (7) by means of a system of sliding surfaces (14,15) in order to displace the bolt crucially. The bolt (7) has supporting means (27,28) for pivotally supporting holding pieces (17,17'). Said holding pieces and the interior walls of the insert core (2) have a second system of sliding surfaces (24,26) which owing to the axial movement of the bolt (7) cause a deviation of the holding pieces (17) having in its free end area said projection (21) intended to exert said force. Preferably, the thread of the screw (5) and the threaded bush (4) have a pitch of more than 1 mm per revolution, and preferably, the bolt (7) is led through a laterally expanded transverse hole of a threaded bush (4), and a transverse bore of the insert core (2) and the threaded bush (4) guided in it are designed in such a form-locking way that a lateral displacement of the threaded bush (4) along the transverse bore of the insert core (2) is possible.

Title: Apparatus and method for use in marine seismic surveying
Inventor: JOHNSTON OTIS A
IPC: G01V1/137
Filed: 1991-11-27
Granted: 2001-03-06
Abstract: The invention provides a seismic transmitter source system which includes a flotation device (10) that contains a plurality of air tight chambers (12a-c) in a serial connection. A separate one-way check valve (22a-c) is placed between each adjacent pair of the chambers. Pressurized air is continuously supplied to an end chamber.  The one-way check valves enable the air to pass to the remaining chambers in one direction. A transmitter subarray containing a plurality of spaced apart transmitters (52) is suspended from the flotation device by means of several pivotly connected links (72a-n). The front end of the transmitter array is connected to a point near the front end of the flotation device. During operation, the seismic transmitter source system is pulled from a tow point (99) located at the front of the flotation device, pulling both the flotation device and the transmitter subarray in substantially a horizontal straight line position while maintaining the transmitter subarray at a near constant depth below the water surface.

Title: Signal processing incorporating signal tracking, estimation,and removal processes using a maximum a posteriori algorithm, and sequential signal detection
Inventor: BORRELL RONALD A
IPC: G01S7/527
Filed: 1993-03-22
Granted: 1996-08-06
Abstract: A system (10) and method (10A) for automating signal tracking, estimation of signal parameters, and extraction of signals from sonar data to detect weaker signals. A maximum a posteriori (MAP) algorithm processing provides a track output of thesignal which is used as a guide or template to provide optimal spectral integration on an unstable or frequency varying line. The present invention includes track integration (15), parameter estimation (17), signal track normalization (16A), and sequential signal detection (18). The present invention partitions (12) the input band into frequency subwindows (31-35). For each subwindow (31-35), the strongest signal is tracked, its parameters are estimated, and then the signal is normalized (removed) (17) from the subwindow. This is repeated until the entire subwindow set is processed. Then the subwindows, now with their strongest signals removed, are recombined to form oneinput band. This aggregated procedure represents one processing pass. In the next pass, the entire above procedure is repeated with either the same or new subwindow boundaries. This continues until a predetermined number of passes is completed. Sequential signal detection is provided from one data frame to the next, a problem that is beyond the capability of conventional systems and methods for tracking frequency lines of unknown frequency modulation and amplitude.

Title: Cardiopulmonary resuscitation assist device
Inventor: GEEHAM CALVIN T
IPC: A61N1/38
Filed: 1993-07-13
Granted: 1999-08-03
Abstract: A device providing performance of CPR without need to exert forces of such magnitude that the patient may be injured, and which further provides performance of defibrillation and ventilation. The CPR assist device according to the present invention is composed generally of an elongate column member, handles mounted normal to the column member, a suction cup member mounted at one end of the column member, and a defibrillation system so that the patient may be defibrillated in conjunction with CPR. According to the method of the present invention, an aid giver places the suction cup member of the CPR assist device on the chest of the patient, then grabs the handles and proceeds to alternately press on the chest and pull from the chest. The suction cup member causes the chest to compress and expand, thereby creating a churning action within the chest cavity that resuscitates the patient. An added benefit of the CPR assist device is that the expansion of the chest cavity as the suction cup member is pulled away from the chest will stimulate lung action of the patient. Defibrillation is provided by the aid giver actuating one or more switches on the column member which supplies electrical stimulation at electrodes mounted to the suction cup member. The defibrillation circuit may operate from household current or may be powered by an internal battery.

Abstract: Apparatus and method are disclosed for providing a halo (background region) around selected image data in an anti-aliased image processing system. The anti-aliased image processing system applies a distribution function (601) to an image (impulse) point so that the impulse point contributes to the display (101, 500) for a plurality of pixels. In order to provide a halo. a second or halo distribution function (602), extending beyond the anti-aliasing distribution function (601), is assigned to selected impulse points. For the current pixel, the pixel for which the display attributes are being determined, the contribution to the current pixel from neighboring pixels for both the anti-aliasing distribution function (601) and the halo distribution function (602) are determined separately. Then the contributions from each source are combined to determine the display characteristics of the currently activated pixel. The invention provides a technique for combining or prioritizing contributions from display regions including overlapping sets impulse points.
