Patent EP-0191619-A2 (EP)
Inventor: LYNCH DAVID LAWRENCE
IPC: H03H19/00
Filed: 1986-02-10
Abstract: An automatic linear compression circuit for a telephone «handsfree» loudspeaker is provided. The circuit consists of a variable attenuator the level of attenuation of which is controlled by the input signal level. The input signal is passed through a positive peak detector to obtain a time averaged signal corresponding to the average positive peak values of the input signal and this time average signal is compared against a time increasing reference voltage. As long as the reference voltage is below the value of the time averaged signal a positive attenuator control signal is derived. This positive control signal keeps the attenuator portion of the circuit operative. In the attenuator the input voltage is sampled to a first capacitor. The first capacitor is subsequently connected to and disconnected from a second capacitor a number of times as long as the positive attenuator control signal is present. Each time this is done the voltage on the first capacitor is reduced by a factor depending on the capacitances of the two capacitors. After a predetermined time the voltage remaining on the first capacitor is passed through buffers and another capacitor to provide an attenuated output. The circuit is simple and flexible, permitting wide ranges in the operating parameters to be achieved simply by including one or more variable capacitors.

Abstract: @ A digital integrated circuit comprises a number of registers (A-D) each of which comprises several data bits (BO-B7) and at least one control bit cell (T1, T2). In a normal operation state, all the registers act as parallel input/output registers. In a SHIFT state, the data bits and control bit cells of all the registers are linked together to form a serial shift path between a pair of external terminals (LOOPIN, LOOPOUT) allowing test data to be shifted in or out as required. In a TEST state, each register is set into one of a number of test modes, controlled by the test bit cells (T1, T2) of that register. The test modes include a test generate mode in which the register acts as a pseudo-random number generator, and a test analyze mode in which it acts as a digital signature analyzer.

Abstract: A suspension system (1) for a vehicle having a shock absorber strut (2) with a reciprocal piston rod (4) located within a cylinder (3), and attachments for securing the piston rod and cylinder to spaced parts of the vehicle. An air spring includes a rigid annular canister (20) mounted on the piston rod (4) by a resilient rotatable mount. The canister forms a fluid pressure chamber (27) in conjunction with a flexible diaphragm (35), one end of which is sealingly connected to the cylinder by an annular rigid sleeve (42) which forms an air spring piston. The flexible diaphragm has inner (37) and outer radially spaced portions (38) connected by a rolling portion (39). A rigid member resembling a cutaway can (55) is mounted on the rigid canister portion of the air spring and extends about a predetermined portion of the outer portion of the flexible diaphragm and restrains outward expansion of said portion. Restriction of the outward expansion of only a portion of the flexible diaphragm exerts a lateral force on the strut to counteract the unbalanced lateral forces acting thereon due to the offcenter mounting of the strut with respect to the point of contact of the vehicle wheel with the pavement.

Abstract: The error detection circuit is used in detecting an error in a binary signal of k bits in a logic circuit which carries out a predetermined operation with respect to a modulus number m, where m is equal to 2k-1, zeroth through (m-1)-th codes are assigned to the predetermined operation while an m-th code is prepared as a specific code to monitor and to detect an error in the error detection circuit. The logic circuit may be a modulo-m register circuit, a mpdulo-m coincidence circuit, or a modulo-m calculation circuit. Alternatively, at least two of the modulo-m circuits may be combined to form the logic circuit. If m = 3, the specific code may be (1, 1), as illustrated where a circuit (41) produces a modulo-3 di-bit residue Z(3) from a result value Z produced from two operands whose modulo-3 residues are A and B A calculation circuit (42) produces a di-bit code by operating an A and B and this is (1, 1) if either of A and 13 is (1, 1). A coincidence circuit (43) compares the result residue Z(3) with the said code and generates the code (1, 1) if the compared di-bits are not equal or if an error occurs in the circuit (43). The output of this circuit is buffered in a register (44).

Abstract: An out of plane ring laser gyroscope comprises a frame and a cavity formed in the frame to form a non-planar closed optical path. A gain medium produces two light beams propagating in opposite direction in the cavity. A magnetic device applies a magnetic flux density to the gain medium to allow only light of opposite circular polarizations to lase in opposite directions. The gain medium produces a clockwise beam and an anticlockwise beam that both include right and left circularly polarized components. The magnetic flux density decreases the frequency of one left circularly polarized beam and the oppositely directed right circularly polarized beam. The magnetic flux density increases the frequency the right circularly polarized beam traveling in the direction of the decreased left circularly polarized beam and increases the frequency of the left circularly polarized traveling in the direction of the decreased right circularly polarized beam. These frequency changes are non-reciprocal. The cavity length of the ring laser is adjusted so that only one polarization component lases in the clockwise beam and only an opposite polarization component lases in the anticlockwise beam.

Abstract: There is disclosed herein a base and emitter contact structure for a bipolar transistor which is comprised of polysilicon stripe over an isolation island which stripe extends to a position external to the position of the isolation island and assumes the shape of an emitter contact pad. The emitter contact stripe has a layer of self aligned silicide formed thereover to lower its resistance, and this silicide is doped with both N and P type impurities one of which is selected to have a higher rate of diffusion than the other. A layer of self aligned insulating material is formed over the silicide and polysilicon of the emitter contact stripe. There are anisotropically etched insulating spacers formed on the sides of the emitter contact stripe, and there are silicide base contact stringers formed beside the spacers by anisotropic etching of a layer of doped silicide. A heat drive in step in the process used to make the structure, also disclosed herein, causes the impurities from the two silicide layers to diffuse into the emitter contact polysilicon and into the epitaxially grown silicon in the isolation island. An emitter and a base are and the the attendant base-emitter and base-collector junctions are formed because the faster diffusing impurity overtakes the slower diffusing impurity and passes it to thereby form the base region. The impurities from the base contact stringers also diffuse into the epitaxially grown silicon and their lateral diffusion causes them to link up with the base impurities which have diffused into the epitaxially grown silicon from the silicide over the emitter contact polysilicon.
