Inventor: ROGER JACQUES
IPC: G02B6/44
Filed: 1992-12-29
Granted: 1997-09-30
Abstract: Two identical parts (1, 1') assembled together constitute an optical cable guide rack fixed to the bottom of a chassis (9) fitted with circuit boards (10). Optical straps (13, 13') are guided between supporting members (4) and guide members (4'). Each optical target (14) can be easily placed on standby for connection with its end connecter portion (15) resting between two supporting members (4). It is thus possible to avoid tangling the optical straps (13, 13') and to substitute, with no risk of confusion, any one of the cables (17), connected to the front face of any one of the boards (10), with the target (14) placed on standby. <IMAGE>

Abstract: A method of treating patients with compulsive eating disorders includes the steps of detecting a preselected event indica-five of an imminent need for treatment of the specific eating disorder of interest, and responding to the detected occurrence of the preselected event by applying a predetermined stimulating signal to the patient's vagus nerve appropriate to alleviate the effect of the eating disorder of interest. For example, the preselected event may be a specified level of food consumption by the patient within a set interval of time, or the commencement of a customary mealtime according to the patient's circadian cycle, or the pas sage of each of a sequence of preset intervals of time, or the patient's own recognition of the need for treatment by voluntarily in itiating the application of the stimulating signal to the vagus nerve. In cases in which the disorder is compulsive eating to excess the stimulating signal is predetermined to produce a sensation of satiety in the patient. The occurrence of the preselected event is detected by summing the number of swallows of food by the patient within the set interval of time. In cases where the disorder i compulsive refusal to eat (anorexia nervosa), the stimulating signal is predetermined to produce a sensation of hunger or to supp ress satiety in the patient.

IPC: G10L17/00
Filed: 1993-08-25
Granted: 1997-09-23
Abstract: Apparatus and method for operating a speech password system. The system apparatus records and stores a plurality of alphanumeric models. A user password is enrolled by the apparatus recognizing spoken sounds and comparing spoken password enrollment sounds with each of the alphanumeric models. Each user password is stored in the system by recording a pair of clusters identifying five alphanumeric models closest to and farther from the user spoken password enrollment sounds of the password. The system identifies subsequent passwords byrecognizing a spoken access password and comparing the sounds thereof with each of the cluster identified alphanumeric models and assigning scores representing the similarity of the password access sounds with the alphanumeric models recorded in the pair of clusters. The spoken password access sounds are identified as a previously enrolled password by summarizing the cluster assigned scores and comparing the summation thereof with a predetermined threshold.

Title: Electrical rocker type switch
Inventor: BALABAN DAVID B
IPC: H01H3/60
Filed: 1993-12-06
Granted: 2003-10-07
Abstract: An electrical rocker type wall switch capable of single, duplex and triplex configurations incorporates one or more slightly concave manually depressible rockers. These rockers have a relatively short range of motion from their respective on to off positions. The edges of the rocker lie substantially, flush with the switch cover when in either of their on or off positions.      Switching is actuated by an actuating arm attached to the rocker moving a contact on the end of a movable brush arm in and out of electrical contact with a fixed contact on the end of a contact arm attached to a fixed terminal. One or more brush arms extend from a fixed brush backplate and are formed so as to be resilient.      Switch toggling is achieved by using a toggle spring, held in place on the end of a toggle arm, which is compressed during the first half of travel of the rocker from its resting position and expands as the rocker crosses its midway point toward the second half of travel to its resting position on the other side of the switch.      The toggle spring sits centrally over a spring pivot which has two springs stops on either side of it to support the toggle spring at the on and off position of the rocker.

Title: Method and apparatus for removing artifacts from an ultrasonically generated image of a small cavity
Inventor: EBERLE MICHAEL J
IPC: A61B8/12
Filed: 1992-06-19
Granted: 2001-03-20
Abstract: An apparatus and method for imaging a small cavity is disclosed wherein reference waveforms to be used in obtaining an improved image are generated in vivo instead of in vitro as in the conventional procedure. The reference waveforms are used to strip the imaging signals of noise that otherwise produces artifacts in an image generated from the signals.  The imaging probe is first inserted into a first area of the vascular system to be imaged and reference waveforms are collected. After collecting the reference waveforms, the imaging probe is further inserted into the vascular system to a second area that is to be imaged. If new reference waveforms are required, the imaging probe is simply withdrawn to the first area of the vascular system wherein new reference waveforms are collected, and then the imaging probe is again further inserted to the second area, which then is imaged. The present invention also provides an imaging apparatus capable of imaging close to the surface of the probe and, in this regard, removes artifacts in the imaging waveforms that usually form a corona in the visual image about the perimeter of the probe.

Granted: 2000-02-08
Abstract: A thermoplastic tube for in-field storage or packaging of bales of agricultural products is disclosed.      The tube combines high puncture resistance with an exceptional stretchability, elasticity and good slip properties. The circumference of the tube can be expanded by at least 15% without tearing when stretched in the transverse direction. The tube also shows no substantial permanent deformation 2 hours after being so stretched for a period of time not exceeding 30 minutes and released.      Before feeding a bale, the tube is stretched radially to facilitate the insertion and accommodate bales larger than original diameter of the tube. When regaining the original size, the tube wraps up tightly the bales reducing the amount of air trapped in the tube. Since the tube can be enlarged to a variable extent, it may accommodate bales of different shapes and sizes.

Title: Display pixel balancing for a multi colour discrete level display
Inventor: SILVERBROOK KIA
IPC: G09G3/28
Filed: 1995-03-13
Granted: 1999-09-28
Abstract: In a monochrome display device, it is known to be important to maintain a constant optical centre of illumination with increasing levels of illumination. Therefore, any pixel arrangement will comprise a trade off between the need to maintain an optical centre of illumination and the practical requirements for driving a pixel of a display.  In a full colour pixel display, the need to maintain an optical centre can be partially or substantially relaxed due to the differences between a full colour arrangement and a monochrome pixel arrangement. There is therefore disclosed a pixel arrangement (30) for a full colour display having a relaxed requirement for maintaining an optical centre of illumination, in addition to disclosing a method for constructing full colour pixel arrangements with relaxed optical centring requirements.

Granted: 1999-12-28
Abstract: A method and device are disclosed that utilize a spread spectrum coding process for processing a signal having first and second time portions to achieve unequal error protection of the time portions by variably modulating the power of one segment relative to the second segment. In such a signal, the first segment contains information that is more significant, i.e., more sensitive to error, than the second segment and the power modulator increases the average power of the signal during the first time portion relative to the average power of the signal during the second time portion. Preferably, the power increase of the first time portion is proportional to the power decrease of the second time portion so as to maintain overall system power requirements. The method and device are particularly suited for a digital cellular telephone systems such as DS-CDMA. In such a system, the signal is spread by a single spreading sequence. Also disclosed is a decoding device and method for decoding the signal processed by the above coder utilizing a first decoder to decode the first time portion and a second decoder to decode the second time portion.
