Patent EP-0292173-A2 (EP)
Inventor: WHITEHEAD LORNE A C O MINNESOT
IPC: G02B5/04
Filed: 1988-05-09
Abstract: A light guide has a central path comprising the locus of points which are the centroids of the segments contained within the light guide of all planes which inter­sect the light guide and which are oriented such that the area of each of the plane segments is a minimum. The light guide also has an average cross-sectional dimension com­prising, for each one of the plane segments aforesaid, the average length of those portions of all lines within the light guide which lie on the one plane segment and which intersect the light guide. The length of the light guide is substantially greater than the average cross-sectional dimension of substantially all of the plane segments. The fractional rate of change, along the light guide, of sub­stantially all randomly selected cross-sectional dimensions of the light guide, is substantially less than the recip­rocal of the average cross-sectional dimension of substan­tially all of the plane segments aforesaid. The radius of curvature of the central path at substantially all randomly selected points on the central path is substantially greater than the average cross-sectional dimension of sub­stantially all of the plane segments aforesaid. 
     A variety of techniques are used to effect contin­uously controlled emission of light from the light guide. For example, the light guide may contain a mechanism which causes light to escape from the light guide at a rate which varies along the length of the light guide, such that the amount of light escaping, per unit length, along the light guide has a selected distribution of values. Alternatively, the light guide's central path may be non-linear. As a further alternative, the average cross-sectional dimension of each of the plane segments aforesaid may be non-constant. As yet another alternative, a first portion of the light guide may comprise prism light guide material and the remaining portion may be such that a substantial portion of light incident thereupon is allowed to escape therethrough.

Abstract: In a cable-steerable endoscope, borescope, or guide tube in which opposing cables (34, 36) are displaced to deflect the tip of the instrument, a self-adjusting mechanism in the control section ensures that a maximal differential force and a minimal total force is applied to the two steering cables (34, 36). The self-adjusting mechanism has a frame (52, 53) that is affixed within the control section and a slider plate (56) that is slidably disposed on a longitudinal rail (54) of the frame (52, 53). The slider plate projects outwardly to engage ends of the cable sheaths (42, 44) for the steering cables. The slider plate engages the frame rail (54) when there is force on only one steering cable to lock the slider plate against sliding motion. When there is no force, or equal forces on the steering cables, the slider plate moves proximally on the frame. This arrangement, along with a reset spring, automatically takes up unneeded play or slack in the cables and also avoids the simultaneous tensioning of the two cables that can produce high steering forces and that can damage the steering section.

Abstract: A thermosensor used for an automotive air conditioning sysaem is disclosed. The thermosensor disposed in a rear side space of an instrument panel of an automobile comprises a casing having an passage and fans driven by a motor. The fans suck air in a passenger compartment to the passage to be sensed by a thermistor disposed in the passage. A circuit board disposing a conductive member on one surface thereon couples the thermistor and one terminal of lead wire connected to a controlling apparatus. The conductive member on one surface of the circuit board is effectively exposed to air in the passenger compartment in order to reduce unnecessary thermal influence from air in the rear side space of the instrument panel thereby the thermistor can sense temperature of air in the passenger compartment exactly.

The assembly may include dielectric layers forming a capacitor stack. A.C. current through the stack is matched in strength to the Seebeck-generated thermoelectric current circulating in each bimetallic layer. The resulting current snakes through the stack to cause Peltier cooling at one heat surface and heating at the other. A.C. operation at a kilocycle frequency enhances the energy conversion efficiency as does heat flow parallel with the junction interface.

Abstract: The method of observation involves the scanning of a celestial body (T) from a spacecraft (S) carrying an observation system which scans with reference to a scanning axis. Two signals (A, B) are formed (16) in succession, each of which is produced by scanning the same strip of ground (BT) in the same direction of movement. In both these signals, a characteristic transition (A1, B1) representative of the same characteristic point in this strip of ground is detected (17). The relative position of these transitions in these signals is recorded (18). From any difference there may be between these relative positions, a possible angular velocity ( omega ) of the spacecraft is calculated (19), taking into account the time interval separating the instants at which each of these transitions appeared in the said signals. …<IMAGE>…
