Patent EP-0324326-A1 (EP)
Inventor: NAEVE AMBJORN
IPC: G02B27/22
Filed: 1988-12-20
Abstract: A display or presentation device, e.g. for advertising pur­poses, comprising two parabolic mirrors (11,12) whose ref­lective surfaces face one another and in which the focus of one mirror (11,12 respectively) is located in the cent­ral part of the other mirror (12,11 respectively). 
     For the purpose of producing a certain visual effect, each of the mirrors (11 and 12) has a respective aperture (111 and 121) provided centrally thereof. One of the apertures (111) is intended to receive an object (13) therein, optio­nally a movable object, and the other aperture (121) is intended for the presentation of a true image (14) of the object. 
     A planar glass sheet (30) may be placed adjacent the other aperture (121) or between the two mirrors (11,12). 
     In order to provide a longer movement path for the image (14), the device may include two or more pairs of parabolic mirrors (11-12; 51-52) positioned with a common centre line of the respective foci (110,120,510,520) of the mirrors.

Abstract: The two-phase stepper motor is controlled by observing the opposing voltage Ug induced by the rotor rotation. To this end, an automatic control circuit Sy is provided in addition to the higher-level control device ST, which circuit Sy detects the currents i1, i2 of the two phases increasing from zero and compares them with one another, and steps the motor on if said currents are equal ( DELTA i=0). This causes a reduction of the currents i1, i2 in the two windings. After a commutation pause tp, the currents i1, i2 increase once again corresponding to the new magnetic latching position. The current difference signal  DELTA i is used to control the stepping cycles and in the accelerating process, during the braking process and also for identifying reversal of the rotation direction. The method facilitates stable operation of stepper motors, free of stepping errors, without any previous knowledge of the load conditions. <IMAGE>

Abstract: A remote sensing tonometric catheter apparatus (20) and method for sampling of a fluid or gas property of interest in a hollow internal organ. The tonometric catheter (20) assists in early detection of the problems of stress ulceration and/or intestinal ischemia. The tonometric catheter (20) has one or more sampling chambers (40) for introduction into a hollow internal organ or an area adjacent thereto. The tonometric catheter (20) has an electric sensor (42) for developing a signal indicative of the condition of the organ. Electric sensor (42) is in communication with the sampling chamber (40). The sensor (42) has a conductor (56) coupled therewith for conveying the signal to a location outside the organ such that the condition of the organ may be remotely determined. Preferably, the wall (36) of the sampling chamber (40) is freely permeable to the gas or fluid to be measured by the sensor (42), but is poorly permeable to other gases or fluids which may interfere with the sensor (42). The method is accomplished by introducing the catheter into the organ such that the sampling chamber is disposed at a portion of the wall of the organ. The sampling chamber is left in position at the wall of the organ for a time sufficient to allow the fluid or gas of interest to diffuse into the sampling chamber. The concentration of the fluid or gas of interest is analyzed. The pH of the wall of the organ may be calculated based on the concentration of the fluid or gas property of interest.
