Patent number: 9035787Abstract: A method, device and/or a system of centralized management and emergency allocation of deployed defibrillators each having associated communication modules. A central server may process a message from a communication module associated with a defibrillator, and then analyze a photograph and/or a video of a defibrillator display to compare it to a set of expected visual markers using a pixel algorithm of a pixel analysis module. The central server may then determine the operational status of the defibrillator such as whether it is in a nonfunctional status. The central server may then send alerts to the communication module and notifications to the an organization owning or leasing the defibrillator. The central server may also send alerts to the communication module based on a nearby emergency call, provide geospatial mapping of defibrillators to improve deployment efficiency and/or establish bi-directional communication between the operator of the defibrillator and a medical professional.Type: GrantFiled: March 13, 2014Date of Patent: May 19, 2015Assignee: NEW ANNUVIA COMPANY, LLCInventors: Micah Bongberg, Jan Gerritsen, Walt Maclay, John Hoving, Mark Brinkerhoff

Patent number: 5784489Abstract: An apparatus and method for syntactic signal analysis which is suitable for processing signals which deviate, within a freely selected margin, from a set of signals predetermined by a grammar, the apparatus being provided with a feature unification mechanism which detects violations of features, and an adaptive threshold mechanism coupled thereto. The feature unification mechanism, which processes the features in groups so that rapid processing is obtained, determines a violation score, thus providing a measure of the deviation of the analyzed signal from the set of signals predetermined by the grammar and indicates what elements of the signal are not satisfactory so that these can be corrected if necessary. The adaptive threshold mechanism enables a number of analyses to be delivered each having a violation score, so that on the basis thereof, in combination with other factors which may be available, it is possible to select the best analysis.Type: GrantFiled: July 2, 1996Date of Patent: July 21, 1998Assignee: Oce-Nederland, B.V.Inventors: Eduardus J.W.

Patent number: 4982467Abstract: A wash additive combination is provided which is loaded into a washing machine at the start of a wash cycle, and which releases a wash additive, such as a fabric softener, into the rinse solution. The combination comprises a wash additive packet of a foam substrate material having a first and a second stable conformation of differing surface area, and a wash additive deposited thereon. A dispenser is provided for mounting atop a washing machine agitator, and into which the packet may be releasably placed, after arranging the packet in its lesser surface area conformation.

Patent number: 4625145Abstract: In a color display tube having an electron gun of the "in-line" type for generating three electron beams situated with their axes in one plane, the electron gun includes curved field shapers at the end from which the beams exit into frame and line deflection fields. Each field shaper includes two or more plates of ferromagnetic material aligned along a curve and spaced from each other by slots.

At least the ends of each field shaper which are most remote from the plane have substantially flat plates extending in the direction of the central electron beam axis. By using such field shapers the losses in the line deflection field are small and substantially undistorted, while a desirable pincushion-shaped distortion of the frame deflection field is intensified.Type: GrantFiled: October 3, 1984Date of Patent: November 25, 1986Assignee: U.S. Philips CorporationInventors: Jan Gerritsen, Piet G.
