Publication number: 20130150748Abstract: The present invention consists of an apparatus for the on-line identification of drug effect using drug interactions and physiologic signals, in particular the interaction between anaesthetics and analgesics combined with the electroencephalogram for precise assessment of the level of consciousness in awake, sedated and anaesthetised patients. In a preferred embodiment the apparatus comprises: two infusion devices, for example syring pumps, which are connected to the patient (1) adapted to deliver hypnotics (2) and analgesics (3). The infusion data from the pumps are fed into an interaction model (5); an interaction model characterized by a Neural Network which is adapted to estimate the parameters of the model online and in real-time for drug interaction between anaesthetics and an analgesics, an EEG instrumentation amplifier; a processing unit adapted to calculate an EEG index of the level of consciousness (ELC); a fuzzy logic reasoner adapted to merge extracted EEG parameters into an index.Type: ApplicationFiled: July 18, 2011Publication date: June 13, 2013Applicant: QUANTIUM MEDICAL S.L.Inventor: William Kai Jensen

Patent number: 4480287Abstract: An improved electronic circuit module retainer apparatus having interlocking, wedge-shaped components which are slotted and keyed together to allow tightening using a single screw which can be turned from the module insertion side of a module enclosure. A module retainer has a minimum of three interlocking parts which are held together by a tightening screw. A center body of the module retainer has holes for attaching it to a module or a module enclosure; it has a U-shaped channel with a square cross section and sloped ends. Each end body has a keying guide extending from a sloped end. A screw extends through a clearance hole in an end-body, then through the center body U-shaped channel and finally into a threaded hole in an opposite end body. When the screw is tightened, the end bodies slide along the sloped ends of the center body causing them to wedge the module against the module enclosure walls.Type: GrantFiled: December 27, 1982Date of Patent: October 30, 1984Assignee: Raytheon CompanyInventor: Kai Jensen
