Title: Measuring head for weapon strike simulator
Inventor: MALSBENDER DIETER DIPL ING DIP
IPC: F41G3/26
Filed: 1997-10-17
Granted: 1998-10-22
Abstract: The invention relates to an measuring head for a simulator for simulating the firing of especially long-range weapons. The inventive measuring head has an illumination emitter (10) for illuminating a target with a pulsed laser beam in order to simulate fire, a receiver (11) for the laser light reflected in the target and a signal processing element (12) for determining the spatial and temporal position of the target. The laser beam emitted by the illumination emitter (10) is a vertical laser line which illuminates a defined solid angle (emittance angle) homogeneously and which can be deflected horizontally. This enables several targets to be detected with high resolution in a relatively large measuring field. The receiver (11) has a vertically oriented high resolution detector line (14) with a solid viewing angle which is identical to the emittance angle. The detector line (14) is made up of a plurality of individual detector elements (141) arranged one above the other. An independent channel (121) is allocated to each detector element (141) for processing signals. The illumination emitter (10) and the receiver (11) are synchronised with each other in such a way that the emittance angle and the viewing angle of the detector line are congruent at all times.

Title: Heat exchanger sublimation process to remove carbon dioxide from respiration gases in anaesthetic applications requires less power than prior art
Inventor: RIECKE MICHAEL
IPC: A61M16/22
Filed: 1999-03-11
Granted: 2000-07-27
Abstract: In a process to remove carbon dioxide (C02) from exhaled respiratory gases, the exhaled gases are first fed with an anaesthetic to a contra-flow heat exchanger (1) where they are brought to a temperature between the water dew point, and the sublimation temperature of C02. The gases are then cooled to below the sublimation temperature of C02, which is released as dry ice. The residual gases are then heated in the heat-exchanger (1) and returned to the respiration system. The flow of gases is reversed within the heat exchanger (1), so that gases emerging from the cooling chamber (2) take up the condensed water and anaesthetic. The cooling chamber (2) is then heated to above the sublimation temperature of C02, the resulting C02 being discharged via a gas tube (4).
