Title: Multilayer conductive appliance having wound healing and analgesic properties
Inventor: FLICK A BART
IPC: A61N1/20
Filed: 1998-09-22
Abstract: A dressing (110) for promoting healing and pain relief of the body of a living organism having a pathologic condition has at least one layer of conductive material (114) having a resistance no greater than 1000 .OMEGA./cm2. When placed proximate a portion of the body of the living organism suffering from the pathologic condition (5), the dressing alters the electrodynamic processes occurring in conjunction with said pathologic condition to promote healing and pain relief in the living organism. When used as a wound dressing, the conductive material (114) is placed in contact with tissue (21) around the periphery of the wound and with the wound (19), lowering the electrical potential (23) and resistance (27) of the wound (19) and increasing the wound current.  In an exemplary embodiment, the conductive material (114) is a multi-ply nylon fabric (194) plated with silver by an autocatalytic electroless plating process and with the plies in electrical continuity.  The dressing provides an antimicrobial and analgesic effect. The dressing (110) may be provided for numerous applications (130, 150, 160, 170, 180, 184, 200, 210, 220, 230) and may include other layers such as an absorbent layer (116), a semi-permeable layer (118) and additional layer of conductor material (129). Multilaminate embodiments of the present invention (20) exhibit conductive material concentration gradients and, potentially, a capacitive effect when sequential conductor layers (24, 26, 28) are insulated by intervening layers (22).

Title: A motion detection circuit and a noise suppression circuit including the same
Inventor: SANO TOSHIYUKI
IPC: G06T7/20
Filed: 2000-06-09
Abstract: An interframe difference signal is generated from the video signal and its one-frame delayed video signal. A filter removes a carrier color signal from the interframe difference signal to output the interframe difference luminance signal. A first motion judging circuit judges a motion in the video signal at a target pixel from the interframe difference luminance signal to output a first motion judging result in accordance with a first edge detection signal. A second motion judging circuit judges a motion in the video signal at the target pixel from a luminance signal and the carrier signal in the interframe difference signal to output a second motion judging result in accordance with a second edge detection circuit. The first and second motion judging results are combined. A majority determining circuit determines majority of the combined result from adjacent Q pixels in accordance with a third edge detection signal. A circular signal generation circuit generates a coefficient K according to the result of the majority determining circuit. The interframe difference signal is multiplied with k to generate a circulation signal. A subtractor subtracts the circulation signal from the video signal to generate an output video signal of which noise is suppressed.

Title: A surge suppression network responsive to the rate of change of power disturbances
Inventor: FUNKE JAMES
IPC: H02H9/04
Filed: 2000-06-02
Abstract: A surge suppression network for single and multiphase ac systems has a voltage clamping device connected in series with a gated crowbar device across the supply voltage in parallel with the load to be protected. A trigger circuit gates the crowbar device on in response to a specified rate of change of the supply voltage indicative of a surge. For higher levels of surge current shunting, pluralities of clamping devices and crowbar devices can be connected in parallel with a single trigger circuit simultaneously tinning on all of the crowbar devices for each phase.  For crowbar devices such as TRIACs with different response characteristics to positive and negative surges and for unipolar devices such as SCRs, positive and negative subnetworks are connected in anti-parallel across the load.

Patent CA-2316544-A1 (CA)
Inventor: SOHRABY KAZEM A
IPC: H04B10/572
Filed: 2000-08-21
Abstract: A method is provided for verifying that optical signals are properly routed between inputs and outputs of an optical cross-connect according to the prescribed routing paths defined in the cross-connect map. More specifically, optical signals are independently tagged at the cross-connect input ports with connection verification messages containing identification information. Connection verification messages can include, among other information, a message identification, incoming and outgoing wavelength information, incoming and outgoing port information, a time stamp, user verification data, and so on. At the cross-connect output ports, the messages are retrieved (and optionally removed) from the optical signals so that the identification information from the retrieved messages can be compared to the routing defined in the cross-connect map. If an optical signal is verified as not being routed according to the prescribed connection defined in the cross-connect map, then remedial action, such as tearing down the connection, can be initiated. By applying the tag to the optical signal, cross-connections can be verified in cross-connect applications employing one optical signal (i.e., wavelength) at each input and output port or applications employing a WDM signal having many optical channels of different wavelengths at each input and output port.

Abstract: La présente invention concerne des anticorps anti-IL-12 humaine à hétérodimère p75 spécifique, se caractérisant par une plus grande puissance et une plus grande efficacité dans la neutralisation de la bioactivité d'IL-12 humaine que les anticorps monoclonaux connus anti-IL-12 à hétérodimère spécifique. Les anticorps à hétérodimère spécifique reconnaissent un ou plusieurs épitopes de l'hétérodimère p75 d'IL-12 humaine, mais ne se lient pas à la sous-unité p40 seule. Les anticorps anti-IL-12 à hétérodimère spécifique neutralisent la bioactivité d'IL-12 de singe rhésus avec une puissance similaire à celle permettant de neutraliser la bioactivité d'IL-12 humaine, ce qui en fait des antagonistes utiles d'IL-12.

Title: Procedure to reduce the pressure and temperature on the front of a missile at ultrasonic speed
Inventor: SRULIJES JULIO
IPC: B64C23/04
Filed: 2000-11-02
Abstract: A procedure is suggested to reduce pressure and temperature on the front of a missile at ultrasonic speed whereby a spike with a spherical, ellipsoidal, or drop-shaped mount is used on the front end. In contrast to conventional shapes, the sensitive nose of the missile is protected from damaging pressure and temperature, even at high angles of incidence. This makes it possible to create missiles that are highly manoeuvrable at high ultrasonic speeds without high pressures and temperatures arising at the front. The resistance and hence the required thrust of such a missile is strongly reduced when the invention is used which correspondingly increases the range and flight duration of such a missile.
