Title: Peripheral nerve stimulation device for unassisted nerve blockade
Inventor: VLOKA JERRY DARIUS
IPC: A61B17/00
Filed: 1996-04-10
Abstract: The present invention is directed to an apparatus for locating and anesthetizing peripheral nerves. The apparatus of the present invention enables an operator to independently complete a nerve blockade procedure, without the need for an assistant. The apparatus includes a generator (12) which provides an electrical stimulus within a selected range. Adjustable control knobs (14) located on the generator enable an operator to designate the selected amperage range. The apparatus is adapted for accepting a syringe (16) for storing and administering anesthesia, and a tube (18) for carrying the anesthesia from the syringe to a disposable anesthesia needle (24). An electronic cable (28) connects the needle to the generator for delivering the electrical stimulus to the needle (24). The apparatus includes a remotely located foot pedal (44) connected to the generator (12) by a coupling cable (42), which enables the operator to control and modify the magnitude of the electrical stimulus. The addition of the pedal (44) leaves the operator's hands free for unassisted nerve blockage procedure under sterile conditions. The present invention also discloses a method for operating the apparatus.

Patent CA-2239051-A1 (CA)
Inventor: WIKLUND SVEN
IPC: H04M3/02
Filed: 1996-12-02
Abstract: In generating a ringing signal of predetermined frequency and shape between the A- and B-wires (LA, LB) to a subscriber's station (ZL) in a telephone network, the ringing signal is directly injected in or superposed on the DC-levels of the wires. A voltage difference converting means (1) converts any voltage difference between the A- and B-wires (LA, LB) into a first current (I1). A signal generating means (2) generates a first voltage of the frequency and shape of the ringing signal to be generated, and a signal converting means (3) then converts the first voltage into a second current (I2). In a summation node (4) the first current (I1) is subtracted from the second current (I2) to obtain a third current (I3), and this current is converted by passing it through a resistor (R1) to a second voltage. The second voltage is buffered (5) and is again converted to a fourth current (IR) by applying the voltage to resistor (RDC). This fourth current (IR) is amplified by current amplifiers circuits comprising operational amplifiers (6, 7), and is then supplied to the A-wire (LA) and drawn from the B-wire (LB).

Inventor: SONODA TAKASHI
IPC: F01K25/00
Filed: 1998-08-25
Abstract: Easy plant starting is provided in hydrogen burning turbine plant for burning hydrogen and oxygen to generate high temperature steam for thereby driving turbine.  There is constructed a semi-closed cycle such that low temperature steam from compressor 1 enters combustion chamber 2, hydrogen and oxygen are burned in the combustion chamber 2 to become high temperature steam for thereby driving turbines 3 and the steam gives exhaust heat at heat exchanger 4 and returns to low pressure compressor 1-1.  Steam from midway of the heat exchanger 4 enters low pressure turbine 6 for work therein and is condensed to water and the water from condenser 7 is heated at heat exchangers 4-4, 4-3, 4-2 to become steam for driving high pressure turbine 5 and returns to the combustion chamber 2 through the heat exchanger 4. Auxiliary boiler is provided at inlet side of the compressor 1 and the high temperature steam generated at the combustion chamber 2 at starting time is diluted and supplied into the turbine 3, hence the starting can be done smoothly.

Title: Fraud prevention in a telecommunications network
Inventor: BUSUIOC MARIUS NICOLAE
IPC: H04M15/00
Filed: 1997-03-26
Abstract: A method and system for detecting fraud in a telecommunications network matches information on individual calls to a series of rules (18). For each rule (r), a threshold (Tr) is defined, and if the fit of an individual call to that rule is better than Tr an alarm is generated. All call records resulting in alarms are stored within a positive matching file. Likewise, calls which just fail to meet the criteria, within a given tolerance level .THETA., are stored in a separate negative matching file. The entries in the positive and negative matching files are then checked by skilled operators to determine which in fact represent true fraud. On the basis of those validations, a decision module within the system automatically calculates and implements the necessary changes to the thresholds (Tr) by means of a feedback loop.

Abstract: An insulation-piercing connector interconnects an insulated conductor and a ribbon conductor embedded in an electrically insulating body. It comprises an insulation-piercing contact formed with a contact body and a tapered contact portion, and a housing device. A hole is made through both the electrically insulating body and ribbon conductor, this hole having a larger-diameter hole section and a smaller-diameter hole section separated by an annular abutment surface formed at least in part by one face of the ribbon conductor. The contact body comprises a larger-diameter body section inserted in the larger-diameter hole section, a smaller-diameter body section inserted in the smaller-diameter hole section, and an annular shoulder surface applied to the annular abutment surface to make contact with the ribbon conductor. The tapered contact portion has a threaded shank screwed in an axial threaded hole of the free end of the smaller-diameter body section to secure the tapered contact portion to the contact body. The tapered contact portion pierces the insulation of the insulated conductor to make contact with this conductor, and the housing device holds the tapered contact portion in contact with the insulated conductor to thereby establish an electrical connection between the insulated conductor and the ribbon conductor through the insulation-piercing contact.
