Title: Self-blunting needle medical devices and methods of manufacture thereof
Inventor: SAHI CARL R
IPC: A61M5/158
Filed: 1997-12-15
Abstract: A self-blunting needle medical device comprises a needle cannula (18) fixed to a hub (20) having a receiving structure therein such as ferrule (22) and a movable blunting member (14) movably received within the cannula (l8). Ferrule (22) defines a sleeve bore (38) extending therethrough, within which both the cannula (18) and the movable member (14) can be received and which establishes a coaxial relationship between them. The ferrule (22) defines a first guide surface (40) for directing the blunting end (14a) of the movable member (14) into the central bore of the cannula (18) during assembly. A second guide surface (42) performs the function of guiding the proximal end (18b) of the cannula (18) into ferrule (22) for mounting therein.  Typically, the cannula (18) has a tissue puncture tip (18a). When the movable member (14) is retracted into the cannula (18), the puncture tip (18a) is exposed for use, e.g., injection into tissue. The movable member (14) is then moved to an extended position in which blunting end (14a) projects beyond the puncture tip (18a), to render the device safe with regard to subsequent accidental needle sticks.

Title: Reliance server for electronic transaction system
Inventor: SUDIA FRANK W
IPC: G06Q10/10
Filed: 1997-12-11
Abstract: Managing reliance in an electronic transaction system includes a certification authority issuing to a subscriber an attestation of a binding of at least one public key of the subscriber to at least one attribute, and forwarding to a reliance server, information about the issued attestation. The reliance server maintains the forwarded information about issued attestation. The subscriber forms a transaction and then provides the transaction to a relying party. The transaction includes the attestation or a reference thereto. The relying party sends to the reliance server a request for assurance based on the transaction received from the subscriber. The reliance server determines whether to provide the requested assurance based on the information about the issued attestation and on the requested assurance. Based on the determining, the reliance server issues to the relying party an authorization message providing the assurance to the relying party.

Title: Method and device for measuring systolic and diastolic blood pressure and heart rate in an environment with extreme levels of noise and vibrations
Inventor: DHANANTWARI AMAR C
IPC: A61B5/022
Filed: 1999-11-24
Abstract: A method and a device for measuring systolic and diastolic blood pressure and heart rate in an environment comprising extreme levels of noise and vibrations is disclosed. Blood pressure signals corresponding to the heart beat are detected using a first acoustic sensor placed on a patient near an artery. A second acoustic transducer is placed on the patient away from the artery for detecting noise and vibrations. Pressure is applied to the artery forcing the artery to close. The pressure is then reduced and while reducing the pressure the acoustic signals detected by the first and second acoustic sensor as well as a signal indicative of the pressure applied to the artery are provided to a processing unit. The signal of the first acoustic sensor is then processed using an adaptive interferer canceller algorithm with the signal of the second acoustic sensor as interferer. From the processed signal heart beat pulses are determined and relating the heart beat pulses to the pressure signal provides the systolic and diastolic blood pressure. Use of the adaptive interferer canceller provides good results for measurements performed under extreme levels of noise and vibrations such as aboard a helicopter.

Inventor: SWEET EARLE C
IPC: A47J31/053
Filed: 2000-04-28
Abstract: The present invention comprises an apparatus and methods for making herbal extracts. The apparatus employs a percolation vessel having a filter and discharge valve. A heater is provided to heat the contents of the vessel to up to about 60°C during the cold percolation process. A control is provided to monitor the contents of the vessel and regulate the heater output to obtain and maintain the proper temperature. A pump draws the output of the vessel and recirculates it to the vessel top so that the vessel effluent passes through the vessel charge. The method entails continuously percolating a solvent through a bed of herbaceous material in the vessel at a temperature between room temperature and about 60°C to produce an extract comprising active principles contained in the herbaceous material. The thus produced extract is highly concentrated and contains a large proportion of the active principles in the raw material. The thus-produced extract can be used in lower unit doses to provide enhanced medicinal treatment.

Abstract: In the elevator installation with hoistway doors according to the invention, the door panels (25, 70) can be laterally displaced beyond the width of the hoistway, and/or they can be at least partially displaced into the hoistway wall according to the invention. This results in an elevator installation with improved utilization of building space, which also requires less effort to install. The door frame of the hoistway door assembly according to the invention is transformed into a flat, wide hoistway wall module with integral hoistway doors. By this means, building space hitherto required in the hoistway by the hoistway wall is reduced. The hoistway wall module is either inserted between the landing floors, or else several such hoistway wall modules are fitted together vertically and form a largely freestanding modular hoistway wall which forms between the elevator installation and the building an interface which is either self-supporting or supported individually on each floor.
