Patent EP-0345803-A2 (EP)
Inventor: WATKINS BAXTER R
IPC: A61G5/04
Filed: 1989-06-09
Abstract: A latch (50) for each of a pair of cushioning arms (18, 20), respectively, of a stair-climbing wheelchair (10). The latch (50) for each arm (18, 20) includes a first member (52) coupled to the arm (18, 20) and a second member (56) coupled to a fixed support (60) of the wheelchair (10), with the second member (56) being coupled to the armature (66) of a solenoid (68) which is energized to unlatch the arm (18,  20) from latched relationship with the support (60) when it is desired to use the arm (18, 20) for cushioning purposes. An ultrasonic transducer (80) coupled to the wheelchair (10) adjacent to each latch (50), respectively, provides signals to energize the respecting latch solenoid (68) when the arm (18, 20) is to be unlatched. To latch each arm (18,  20), the adjacent edge margins of the two members (52, 56) are bevelled so that, during upward movement of the arm (18, 20), such as by movement of the wheelchair from an inclined position to a horizontal position, the members (52, 56) are spread apart and a first spring (72) biases the two members (52, 56) back together in coupled relationship to each other. When the latch solenoid (68) is energized, the second member (56) is moved away from the first member (52) to allow a second spring (25, 27) to pull the arm (18, 20) down and into an unlatched position. A limit switch (76) senses when each arm (18, 20) is latched.

Abstract: A device for connecting optical fibers is formed by inserting one or more fibers into at least one end of a capillary tube (10). The bore (12) is tapered to facilitate fiber insertion. To taper the end of a bore, the tube (10) is rotated about its longitudinal axis (11) while a first narrow stream (24) of abrasive particles is directed onto the tube end (22). The axis (25) of the first stream (24) is located off the axis (11) of the tube bore, thereby forming a taper that is spherical rather than conical. A second stream (36), the axis of which is coaxial with the bore, is then directed onto the tube end (22) to remove that portion of the tapered aperture adjacent the bore (12), thereby forming a more funnel-shaped aperture.

Abstract: A spread spectrum communication system includes a transmitter and a receiver, and an on-off keying signal is inputted to the transmitter. A carrier signal is modulated by the on-off keying signal, and a spread spectrum signal is produced by multiplying a modulated signal by a first PN code (16) which is repetition of 3-bit data. The spread spectrum signal is transmitted through a transmission antenna (19). In the receiver, a second PN code which is repetition of 4-bit data larger than the first PN code by 1 bit is generated. Therefore, a phase of the second PN code becomes coincident with a phase of the first PN code every 12 bits. Then, a spread spectrum demodulation is performed by multiplying (24) a received spread spectrum signal by the second PN code to reproduce the carrier signal being modulated by the on-off keying signal. The on-off keying signal is restored by envelope -detecting a reproduced carrier signal.

Abstract: A low-noise preamplifier stage, in particular for magnetic heads, which comprises a differential circuit (T₅,T₆) and a single-transistor output stage (T₂). The differential stage has an intrinsic offset voltage, is ground-connectable and can be directly coupled to the magnetic head (L) , the two transistors forming the differential circuit (T₅,T₆) having different bias currents in order to reduce the input equivalent noise. The base terminal of the first transistor (T₅) of the differential circuit defines an input (IN) of the stage which can be connected directly to a terminal of the magnetic head (L); the other terminal of the head can be connected directly to the ground. The base terminal of the other transistor (T₆) of the differential circuit (T₅,T₆) is connected to the intermediate point of a pair of resistors (R₁,R₂) which are mutually connected in series between the single transistor of the output stage (T₂) and a line at reference voltage. In this manner the differential stage (T₅,T₆) biases the output with its offset voltage without requiring additional components for this purpose.

Abstract: The opening and closing movements of an injector valve member which closes and temporarily opens discharge orifices communicating with the combustion chamber of an internal combustion engine is controlled by the fuel pressure in a control chamber (350) arranged at one end of the injector valve member piston (336). Fuel is evacuated from said control chamber (350) through bores (348, 352, 366, 364) when a valve item (76) is lifted off its seat (70) to allow the opening of the injector valve member. Reseating the valve stem (76) results in temporarily moving an intermediate valve body (332) away from a seating surface (354) to provide fast refilling of the control chamber (350) with fuel flowing through bores (360) connected to an inlet bore (358). A sharp closure of the valve member is achieved.
