IPC: A61F13/06
Filed: 1996-12-16
Abstract: Dispositif (10) de traitement d'un durillon permettant d'atténuer les forces s'appliquant à ce durillon situé à la surface du pied du patient. Le dispositif comporte une partie essentiellement plane (12) et, au minimum, une première partie en surépaisseur essentiellement plane (34).

Title: Method and apparatus for controlling command line transfer to a network element
Inventor: RZONCA RICHARD R
IPC: H04L12/24
Filed: 1998-07-09
Abstract: A method and apparatus for controlling command line transfer to a network element. The method and apparatus allow for transfer of command lines such as command lines in the Transaction Language 1 syntax, to a designated network element based upon a wait duration as well as based upon the maximum number of outstanding command lines for which acknowledgement has not yet been received from the network element to whom the command line was directed. As long as the maximum number of outstanding unacknowledged command lines is less than the maximum number set, command lines are transferred to the network element after waiting an amount of time equal to the wait duration. The overall result is that command lines can be directed to network elements with assurance that the commands will be properly executed by the network element. Furthermore, the network element can, to the extent that the command line causes a change in an equipment database associated thereto, appropriately modify the equipment database in the network element and cause such information to be transferred to an overall equipment database containing similar information for all network elements under the control of a network management system.

Title: Method and system for decoding tailbiting convolution codes
Inventor: ATALLAH ISA BISHER
IPC: H03M13/23
Filed: 1998-10-16
Abstract: A method and system for decoding tailbiting convolution codes are disclosed. A set of tailbiting convolutional codes is encoded by a convolutionalencoder having multiple encoding states. A first starting score is assigned to each of the encoding states. A Viterbi algorithm is then performed once on the tailbiting convolutional code to associate an ending score with each of the encoding states. A subset of these encoding states is subsequently selected, within which the ending score of each encoding state meets a certain criterion. The Viterbi algorithm is again performed on the tailbiting convolutional code for each encoding state within the subset to determine the best encoding state as the most likely initial encoding state for the tailbiting convolutional code. A Trellis path of this most likely initial encoding state is utilized to decode the tailbiting convolutional code.

Title: Method and system for delivering a short-message notification
Inventor: BUHRMANN MICHAEL
IPC: H04W4/14
Filed: 1998-10-27
Abstract: In accordance with the present invention, a method and system of the present invention delivers a message notification to a subscriber having a wireless device. The message notification can be received within a wireless communication network such as a cellular telephone network. This message notification is forwarded to the wireless device of the subscriber and indicates that the subscriber has a waiting message. In another aspect of the invention, a message notification can be forwarded to a wireless device by receiving within a wireless communication network a message notification from a private base station that is connected into a premises based local area network. The premises based local area network receives the message from a message provider and stores it within a premises based to personal computer which generates the message notification. Messages may be any form of stored or recorded message, including e-mail, voice-mail and facsimile.

Title: A shared aperture dichroic active tracker with background subtraction
Inventor: LIVINGSTON PETER M
IPC: G01S17/86
Filed: 1998-12-10
Abstract: An imaging self-referencing target tracker (10) for a laser weapon (12).   The weapon generates a first beam of radiation (14) that engages a target (16) to form a beam hit spot  (20)  thereon.     In  a  first  embodiment,   a  target illuminator  (22)  (variant 1)  illuminates the target with a second beam of radiation  (23a).   An optics subsystem  (30) receives and separately images  the  first and second beams (23b, 24)  of radiation.   In a second embodiment,  a blocking filter (40) is implemented rather than an illumination laser to pass  only radiation  at  the  target wavelength,  thereby ensuring that the first and second beams of radiation are separately imaged.  A controller (32) is programmed to steer the first and second beams of radiation to the desired target aim point  (18)  in response to information from the imaged first and second beams of radiation.   The tracker of the present invention tracks the laser hit spot relative to the actual  target  image  in  a  closed  loop  manner,   thereby increasing the probability of accurate target engagement and resulting in a target kill.

IPC: E04B2/74
Filed: 1999-01-06
Abstract: A partition construction includes a partition frame and a markerboard having a flat, dry erasable markerboard surface that erasably receives an erasable medium. The partition further includes top and bottom brackets for attaching the markerboard to the partition frame. The bottom bracket defines a bottom channel that receives a bottom edge of the markerboard. The top bracket defines an opposing top channel that engages a top edge of the markerboard. The top bracket includes an inner component attached to the partition frame and defining an inner portion of the top channel. The top bracket further includes an outer component that is attached to the inner component and defines an outer portion of the top channel. The outer component is configured to be secured after the markerboard is set on the bottom bracket and is pivoted into engagement with the inner components so that, when secured, the outer component, the inner component, and the bottom bracket capture the markerboard.

Patent CA-2259373-A1 (CA)
Inventor: GWINN KENNETH W
IPC: B60R21/276
Filed: 1997-06-25
Abstract: This disclosure describes an airbag in which non-circular vent holes replace traditional circular vent holes. Vent holes, in general, provide a geometric asymmetry in the airbag pattern and induce a stress concentration in the geometry. Investigation of airbag deployments has shown that circular vent holes elongate during the early stages of a deployment. This causes stress concentrations at the two circumferential points of the circle as the fabric is strained. Based on this discovery, the inventors determined that a non-circular vent hole, such as an ellipse or rectangle would be advantageous during the early deployment since this non-circular vent hole has assumed a more natural position during this early straining, thereby not inducing additional straining in this region.

Title: Laser soldering procedure applicable to the joining of pins over printed circuit boards
Inventor: CUBERO PITEL JOSE ANTONIO
IPC: B23K101/42
Filed: 1999-03-09
Abstract: The proposed procedure, that of laser soldering or welding, is an auto-energetic process in which the density of the laser beam is obtained because of the concentration of light beams. Said process involves two metals (alike or disimilar) and, previously to the metallurgical union, same must be positioned in front of the laser head with enough accuracy. The metallurgical union is carried out by direct fusion of the metals to join, not being therefore necessary any filler metal.

Inventor: JONES WILLIAM JOHN
IPC: H01H71/00
Filed: 1999-04-27
Abstract: An improved draw out circuit breaker, having low electrical and thermal resistance between the primary disconnect finger contacts and mating circuit breaker conductors, is achieved using multipoint direct electrical connections between the finger contacts and the corresponding circuit breaker conductors that they attach to. A notch is formed on the surface of the conductor at a location that interfaces with the finger contact and a protrusion is formed on the contact that enables it to partially enter the notch when fully engaged without resting on the bottom of the notch, so that the finger contact is supported by the walls of the notch. The protrusion captured within the notch retains the finger cluster on the conductor and provides a low electrical resistance connection without the use of excessive mating force.
