Title: Coin mechanism with magnetic release system
Inventor: SCHWARZLI JOSEF W
IPC: G07F9/00
Filed: 1997-08-08
Granted: 2004-08-17
Abstract: A coin mechanism is provided with a magnetic release system, for selectively unlocking the coin mechanism when a coin or token having a magnetic component is inserted. A magnet is lodged in a rocker arm which is biased to a locked position in which a latch on the rocker arm engages a rotating member, preventing the rotating member from rotating. The attractive force of the magnet on a coin or token having a magnetic component and inserted into the coin mechanism is greater than the force biasing the rocker arm to the locked position, causing the rocker arm to move toward the coin which thus retracts the latch from the rotating member allowing the rotating member, and thus the mechanism, to rotate.

Title: Universal radiographic/fluoroscopic digital room
Inventor: SIMAK THOMAS
IPC: A61B6/00
Filed: 1996-05-15
Granted: 2001-01-09
Abstract: A universal radiographic/fluoroscopic "room" (100) is constructed by combining X-ray examination system components, electrical and mechanical drive components, and sensing components, under the supervision of a control system (510), to form a universal diagnostic medical imaging system capable of performing radiographic, fluoroscopic, tomographic, and stepped examinations in several different operator-selectable configurations. The control system (510) automatically determines which system components are required to perform that type of examination, moves the components into operational or storage positions as required, and prepares each component for operation. In the "stepped-digital" modes, an X-ray tube (182) and image intensifier (166) execute a series of radiographic exposures at preselected locations. For each step, a test fluoroscopic exposure is performed under automatic brightness control to determine an optimum technique. The technique so determined is converted for use in subsequent radiographic exposure.

Abstract: The switch capacity prediction process of the present invention collects operational measurements from the cellular switch. These operational measurements indicate the frequency of the call events processed by the switch. The other input/output (I/O) time used by the call processor to process messages not related to call processing is separated from the call processing I/O time. A relationship between the other I/O time and the sum of the call processing time and call processing I/O time is determined. A  weighted average is determined from the summation of the products of: the frequency of events and the call processing time, the frequency of events and the call processing I/O time, and the other I/O time. The weighted average is then divided into the call processor occupancy time, in hours, to determine the switch capacity.

Abstract: Identification and quantification of constituents of a sample is achieved by mobility-based electropherograms obtained from capillary electrophoresis, the mobilities being normalized by zero correction followed by division by the mobility of a selected marker. Zero correction is achieved either relative to a separate marker or by calculation based on the same marker. The resulting electropherograms are more recognizable since they more closely resemble the scanned separation patterns obtained with planar gels, and individual constituents of the sample are more easily and reliably identified since their positions in the electropherogram are substantially constant from one electropherogram to the next and hence reproducible to a high degree of accuracy.
