Patent CA-2381125-C (CA)
Inventor: JACQUEMIN MARC G
IPC: A61P7/00
Filed: 2000-07-13
Granted: 2013-04-23
Abstract: The present invention comprises ligands and methods of manufacture thereof as well as pharmaceutical preparations including the ligands. The ligands may be human or humanized monoclonal antibodies and fragments, derivatives and homologs thereof. These may exhibit an unforeseen "plateau effect", i.e. the achievement of only a partial inactivation of a factor involved in hemostasis, in particular in the coagulation cascade, either individually or in combination even in molar excess. The ligands may bind to a factor or a complex of factors resulting in only partially impairing the function of a physiologically functional site of the said factor or factor complex even in molar excess. This makes the ligands particularly suitable for treating coagulation disorders and resulting thrombotic pathologic conditions while minimizing the risk of bleeding. Particularly useful is a property of ligands in accordance with the present invention to allow some physiological function of the affected site even when the ligand is in molar excess. The ligands may be anti-factor VIII antibodies or antibodies against a factor VIII complex, in particular human or human hybrid monoclonal antibodies which bind to factor VIII or a factor VIII complex and at least partially inhibit the activity of factor VIII.

Abstract: A picked up image is separated into a foreground component image and a background component image in real time. An image picked up by a pickup block (74) is separated into a foreground component image and a background component image which are accumulated in an image accumulation block (72) and a charging block (75) performs charging required for the separation. Here, a separation block (91) performs a motion unsharpness remedy to the separated foreground component image and outputs it together with the background component image to a synthesis block (92). The synthesis block (92) synthesizes the foreground component image which has been subjected to the motion unsharpness remedy and input with the separated background component image so as to create a synthesized image and displays it on a display block (73).

Inventor: BINDER YEHUDA
IPC: H04B/
Filed: 2001-09-12
Granted: 2012-05-08
Abstract: An active terminating device (30) for an electrical transmission line with optional line-receiving and line-driving capabilities. The basic device is a two-terminal unit, denoted as a Signal Canceling Unit (SCU), which senses the signal available at its terminals (34a, 34b), and applies negative feedback in order to cancel and absorb the signal. When applied to the end of a transmission line (15a, 15b) as part of wired communication network, the SCU functions as a terminator. When connected in the middle of such wired transmission line, the SCU splits the transmission line into two separate and isolated segments. In such a configuration, the SCU can be used to isolate a portion of a network from signal degradation due to noise or bridge-tap. Furthermore, the two isolated segments may each employ independent communications, such that no interference exists between the segments. In another embodiment, line receiver functionality is integrated into the SCU, designated as a Signal Canceling and Receiving Unit (SCRU) (90). The SCRU can perform all the SCU functions, and also serves as a line receiver in the communication network. In yet another embodiment, line driver functionality is integrated into the SCRU, designated as a Signal Canceling, Receiving and Transmitting Unit (SCRTU) (120). The SCRTU can perform all the SCRU functions, and also serves as a line driver in the communication network. Upon connecting multiple SCRTU's to a continuous transmission line, terminated independent point-to-point communication segments are formed.
