Granted: 2001-02-20
Abstract: A method far immunoassay of a viral antigen is performed on a membrane precoated with an inert protein. Nonimmunological capture of antigen takes place by absorption onto the coated membrane.      Captured antigen binds to a tracer which includes a label conjugated to a specific antibody, the inert protein concomitantly inhibiting nonspecific binding of tracer. The label may be an enzyme which converts a substrate to a detectable product or converts a blocked inhibitor to an inhibitor whereby a second enzyme is inhibited from converting a substrate o a product. The invention includes a kit of materials for performing an assay in accordance with the method of the invention.

Abstract: An infusion system (11) includes fluid-delivery components for delivering a fluid from a separate source (13) of the fluid into a patient, transducer components (51) for producing a signal related to the pressure of the fluid in the fluid-delivery components (17), and identification components responsive to the signal for identifying pressure artifacts characteristic of patient activity. Gravity-fed infusion may be employed as well as infusion with a flow control device (15), and identification may be accomplished with a microprocessor (59) for examining the waveform of the signal and identifying pressure artifacts characteristic of patient activity amidst pressure changes caused by fluid-delivery components (15, 17) so that site checking can be conducted during quiet periods, i.e., times of little patient activity. A method of detecting an abnormal infusion condition includes infusing a fluid into a patient through a conduit (17), with the pressure of the fluid in the conduit (17) being subject to influence by patient activity, monitoring the fluid pressure in the conduit (17) in order to detect pressure artifacts characteristic of patient activity, and performing a site check for abnormal infusion conditions at a time when no such pressure artifacts are detected.
Patent CA-2035706-C (CA)
Inventor: PYNENBURG ADRIAN W
IPC: G09F15/00
Filed: 1991-02-05
Granted: 1999-03-16
Abstract: An improved poster holder is disclosed which can be either wall mounted or suspended from a ceiling. The holder includes two longitudinal extruded panels each having a longitudinal C-shaped flange situated along one of the panel  edges. One flange is inserted within the other one to form a  longitudinal  interlocking hinge connection.  The panels  are movable with respect to each other in the transverse direction about this hinge coupling between an open and a closed position. The flanges are dimensioned in such a way that rotation of the panels with respect to one another in the transverse direction results in one of the flanges being elastically deformed during the first part of the motion, with the resulting stored elastic energy being abruptly released during the second part of the panel motion, thereby giving rise to the holder snapping open or closed. The poster holder formed by the interlocked panels represents an improvement over the prior art by eliminating the need for separate elements for hinging the panels together and biasing the panels open and closed.

Title: Signal routing system
Inventor: SCHAEFFER DENNIS R
IPC: H01Q3/24
Filed: 1990-04-04
Granted: 1994-02-01
Abstract: A signal routing system for use in cellular RF communications systems wherein a signal can be routed to different antennas, effectively switching transmitters between antennas. The switching is accomplished by placing a frequency responsive device (7) between a transmitter and each antenna. The transmitter is then coupled to an antenna through the frequency responsive device (7) that has a resonant frequency equal to the transmitter's frequency. If the transmitter changes frequency, it will be switched to the appropriate antenna through the corresponding frequency responsive device (7). This system permits a sector of a cell to increase the number of frequencies in that sector to handle increased mobile traffic loads.

Title: Method and apparatus for detecting ions and small molecules in aqueous and non-aqueous liquids
Inventor: BAKER MARK D
IPC: G01N27/49
Filed: 1992-01-28
Granted: 1999-08-10
Abstract: Provided is a method and apparatus for detecting electroinactive ions, and electroinactive ions solvated by small molecules including water. The method and apparatus utilizes a microporous ion exchange material such as a zeolite containing initially an electroactive species contained within the pores. The method operates on the principle that when charged species present in solution can access the pores of the micro porous material, an ion-exchange reaction will occur whereupon the electroactive species will exit the micro porous material, being replaced by the charged species. The electroactive species, upon exiting the microporous material, undergoes electrochemical reduction or oxidation at an electrode having a sufficiently high potential applied thereto. The method and detector disclosed herein is size selective since for example zeolites with a pore size comparable to that of the solvated ion to be detected but smaller than other electrolyte components can be utilized. In addition to being used as an ion detector per se, the detector may be used for detecting trace amounts (sub parts per million) of water in non-aqueous media by using the fact that hydrated ration species can readily access the zeolite interior via the pore network thus expelling an electroactive ion into solution. In contrast, the same ration when solvated by organic molecules will be size excluded from the zeolite. The detector can be utilized for the detection of other small molecules using the same principle provided that they form a solvated complexes with electrolyte canons which are not size excluded from the zeolite.

Abstract: A controller that includes a number of switches is associated with a first appliance that has a number of operating states. In at least one of the operating states of the first appliance, the controller responds to certain switch actuations by causing it to perform a task; but when it is in another operating state, the same switchactuations have no meaning insofar as the first appliance is concerned. so the controller responds by transmitting data signals to a second appliance to have it perform a similar task. In this manner, a single controller can be used to control a number of appliances when a particular switch actuation has no meaning in the context of controlling the associated appliance. In an illustrative embodiment of the invention, the keypad of a telephone set is used to select a particular television station. Control signals are sent by the telephone to the television by spread spectrum data transmission over an AC power line. The data transmission format used is in accordance with the CEBUS? standard promulgated by the Electronic Industries Association.
