Patent CA-2182460-A1 (CA)
Title: Terminal block for high transmission rates
Inventor: BEUTLER PETRA
IPC: H01R13/6471
Filed: 1996-07-31
Abstract: The present invention relates to a terminal block for high transmission rates in telecommunications and data processing. The terminal block has a plastic body with at least one row of chambers for insulation displacement contact elements. Slots for shield plates are disposed in transverse walls between the chambers, and extend with axes parallel to the walls. The object of the invention is to provide a terminal block wherein by the configuration of specially-shaped shield plates, an effective reduction of crosstalk and a substantial simplification of assembly of the shield plates and of the cable wires at the insulation displacement contact elements are guaranteed. This is achieved by disposing the chambers of a terminal unit in the plastic body at the smallest possible distance d to each other, and by providing the slots for receiving the shield plates in the transverse walls between adjacent terminal units, the slots extending from a lower side of the plastic body. The distance d between the chambers of a terminal unit are appreciably smaller than the distance D between the chambers of adjacent terminal units.

Title: Surgical instrument for suturing
Inventor: HOEL STEVEN B
IPC: A61B19/00
Filed: 1996-08-28
Abstract: A surgical device is used for manipulating suture needles. The device is formed of two elongate members hinged together. On one side of the hinge, the elongate members form a pair of jaws which are relatively moveable. One the other end of the elongate members there are handles formed which allow the user to manipulate the jaws about the hinge. An arcuate shield is integral with one of the jaws at its center. The shield extends laterally and arcuately from the jaw and covers the opposing jaw. The placement of the shield is such that a needle which is held between the jaws is protected from sticking any one or anything.      The jaw members may be made up of several units forming segmented jaws.

Title: Method and apparatus for automatic pacing threshold determination
Inventor: CONDIE CATHERINE R
IPC: A61N1/365
Filed: 1995-11-13
Abstract: A method and apparatus for automatic determination of a pacemaker patient's pacing stimulation threshold. Circuitry is provided in a pacemaker for obtaining a signal reflecting cardiac impedance, which is known to reliably reflect certain aspects of cardiac function. Circuitry is also provided for monitoring the cardiac impedance waveform during a predetermined capture detect window following delivery of stimulating pulses. One or more values are derived which characterize the morphology of the impedance waveform during the capture detect window associated with each stimulation pulse delivered. These values are compared to predetermined control values in order to assess whether a stimulation pulse has achieved cardiac capture. The assessment of whether cardiac capture has been achieved is also based partly upon the conventional sensing of atrial and/or ventricular cardiac signals occurring during the capture detect window. In one embodiment of the invention, the control values against which impedance waveform characterization values are compared are obtained by delivering a series of stimulation pulses having sufficient energy to ensure that capture is achieved, and by monitoring the impedance waveform during delivery of these pulses.

Patent CA-2217767-A1 (CA)
Title: Low ph skin-treatment composition
Inventor: STRUEWING SHARON
IPC: A61K8/00
Filed: 1996-04-11
Abstract: A low pH skin-treatment composition employs cationic surfactants generally known to be skin irritants and a fatty acid, together with a hydrocarbon component in an oil-in-water emulsion. The addition of fatty acid to the cationic surfactant appears to form a complex which prevents the cationic surfactant from irritating the skin and at the same time substantially reduces pH of the composition. The resulting composition is not skin irritating, and reflects a pH of about 2-4. The composition may be used to restore pH of skin after exposure to alkaline compositions, and as a vehicle for the administration of active agents having an acidic pH.

Title: Enhanced encryption control system for a mail processing system having data center verification
Inventor: RYAN FREDERICK W JR
IPC: G07B17/00
Filed: 1997-10-31
Abstract: A key control system comprises the generation of a first set of predetermined keys K pred which are then used as master keys for a plurality of respective postage meters. The keys are then related to a respective meter in accordance with a map or algorithm. The predetermined master key K pred is encrypted with the date to yield a date dependent key K dd related to the respective meter. The date dependent key is encrypted with a unique identifier or the respective meter to yield a unique key K final that is by the respective meter to generate digital tokens. The Data Center encrypts the date with each predetermined key K pred to yield a table of dependent keys K dd's. The table of K dd's are distributed to verification sites. The verification site reads a meter's identification from a mailpiece being verified to obtain the dependent key K dd of the meter. The verification site encrypts the dependent key K dd with the unique identifier to obtain the unique meter key which is used to verify tokens generated by the meter. In the preferred embodiment, the master key K pred, the date dependent key K dd, and the unique key K final, in the meter are stored in the meter. In an alternate embodiment, the master key K pred is encrypted with a unique meter identifier to obtain the unique key K final which is stored in the meter. The meter then generates its date dependent key K dd, which is used to generate digital tokens.
