The proposed plaster is characterized by the fac t that the reservoir layer which softens at body temperature is separated from the cont rol membrane by a device made of a material which is not permeable to the active substance a nd extends right across the mutually opposing surfaces of the reservoir and membrane and has at least one passage for the reservoir layer.
Patent CA-2186451-C (CA)
Inventor: KURTZ RON
IPC: A61F9/008
Filed: 1995-03-29
Granted: 2009-06-02
Abstract: In one aspect the invention provides a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable and distinct change in slope at a predetermined laser pulse width value. The method comprises generating a beam of laser pulses in which each pulse has a pulse width equal to or less than the predetermined laser pulse width value. The beam is focused to a point at or beneath the surface of a material where laser induced breakdown is desired. The beam may be used in combination with a mask in the beam path. The beam or mask may be moved in the X, Y and Z directions to produce desired features. The technique can produce features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime.

Abstract: In a filter device, an electrically conductive leaf member is mounted on a coupling loop by soldering or the like.  By bending the conductive leaf member and adjusting the bending angle, the number of magnetic lines of force to be blocked, that is, the degree of magnetic coupling is controlled.  Therefore, when the mounting position of the leaf member is predetermined, the parameter of adjustment can be limited to the bending angle, and the adjustment is thereby facilitated.

Granted: 2002-03-05
Abstract: A method and system in a wireless communications network for restricting certaincommunication transactions to specific geographic areas in order to reduce the risk of communications fraud are presented. Initially, a list of communication transactions is stored such that the list includes communication transactions permitted to occur at each of a number of geographic locations.   Thereafter, a communications transaction is initiated. In response to an initiation of the communications transaction, a geographic location of an originator of the communications transaction is determined. Next, the list of communication transactions is automatically scanned for communication transactions permitted to occur at the geographic location. If the communications transaction is not found among the list, the initiation of the communications transaction is thereafter terminated. Alternatively, if the communications transaction is found among the list, the communications transaction is thereafter permitted to continue. The geographic location can include a cell or cells maintained within the communications network.
