Patent EP-0257625-A2 (EP)
Inventor: BOSHOLD KLAUS
IPC: H04L27/38
Filed: 1987-08-25
Abstract: The circuit is provided for the demodulation circuit of a digital radio system, consisting of a demodulator (D), a voltage-controlled oscillator (VCO) and a carrier signal control voltage generator (TR) with a level monitor (P) at its input and an error monitor (F) for the bit error rate at its output. It is designed to synchronise carrier recovery within the shortest possible time following signal interruption, e.g. due to fading. A memory circuit (SP) is disposed between the carrier signal control voltage generator (TR) and the voltage-controlled oscillator (VCO), which ensures that, when the signal returns, the VCO continues to oscillate at the frequency prevailing before the interruption. In the event of an expected interruption in signal transmission, indicated by a rise in the bit error rate above a defined threshold, the error monitor (F) initiates the disconnection of the memory circuit (SP) from the VCO input before the interruption occurs. A sweep generator (W) with a preceding delay circuit (V) connected between the error monitor (F) and the carrier signal control voltage generator (TR) ensures the locking function in any event e.g. in the event of frequency offset following a long interruption. <IMAGE>

Inventor: DOLBY RAY MILTON
IPC: H03H11/24
Filed: 1987-02-26
Abstract: The circuit generates a rapidly changing, yet smooth and controlled, control signal in response to transient signals for controlling a variable resistance element (128) which, in conjunction with a capacitor (126) acts as a narrowing band high pass filter (108) to act on an audio signal component which is thereby limited and is added to or subtracted from a linear component to create a compressed or expanded signal. The steady state control signal is generated from the output of the filter (108) by means of a full wave rectifier (138) and first and second smoothing steps (274,276) (though a single stage may be employed). Overshoot suppression is effected by an amplifier (283) and diode (284) which inject charge rapidly into the capacitor of the second smoothing stage (276). A first additional overshoot suppression circuit (256,279) provides further charging of the capacitor in response to lower frequency signal components. Modulation control signals (MC1, MC2, MC3) which make the compressor or expander less susceptible to control by stop-band signal components, are combined in opposition to the signals in the steady state and overshoot suppression portions of the control circuit. Similar circuits are described for low pass narrowing band filters, which has the capacitor (126) replaced by an inductor. A further overshoot suppression circuit may provide additional charging of the smoothing capacitor in order to compensate in certain cases for the use of modulation control signals.

Abstract: A method and apparatus for securing enlongate members (24, 28) of generally cylindrical form in end-to-end relationship, particularily for forming an optic fiber splice (30). Optic fibers are spliced by pressing a form, preferably an optic fiber of the same diameter as those to be spliced, into a deformable body (8) to create a groove for receiving the ends of the optic fibers in close alignment. To secure the optic fibers, an index matching adhesive is cured by UV irradiation through a glass cover (20) plate bonded to the deformable body.

Abstract: A fluid-damped resilient bush, e.g. for use in a vehicle suspension comprises an outer sleeve (11) and an intermediate sleeve (12) between which a rubber bush (13) is moulded as a one-piece moulding. Cavities (36, 38) are formed between the intermediate sleeve and an inner member (10), which is mounted within the one-piece moulding and sealed to the one-piece moulding by axially separate annular areas of the moulding which engage but are not bonded to the inner member. The cavities communicate with one another and are filled with damping fluid, the arrangement being such that displacement of the outer sleeve relative to the inner member causes displacement of fluid between the cavities.

Abstract: A demand pacemaker which regulates its pacing rate based upon sensed oxygen saturation percentage. The pacemaker employs a two wavelength reflectance oximeter as a sensor (16). The sensor includes an oscillator which sequentially activates red and infrared diodes. The duty cycle of the oscillator is regulated by the relative amounts of red and infrared light reflected by the blood. The pacer monitors (10) this duty cycle via the power drawn by the sensor and determines the ratio of the red and infrared diode activation period as an indication of blood oxygen saturation. The construction of the sensor allows the sensor to operate with only two conductors (20, 22), optimizing it for incorporation in a standard, bipolar pacing lead.

Abstract: An optical data link for transferring data between a pair of connectors (16,24') and for activating an electrical device (10) to which one of the connectors is attached. A light-emitting diode (LED) (30,66) and a phototransistor (68,32) are mounted in each of the connectors, with the LED of each connector visible to the phototransistor of the other connector when the connectors engage each other. The LEDs and phototransistors are connected to respective interface circuits. The interface circuits for at least one of the LEDs limits the current through the LED regardless of the amplitude of a driving signal. The interface circuits for the phototransistors maintain a relatively constant voltage across the phototransistors so that the phototransistors function as current switches. The electrical device (10) is activated in response to closure of a magnetically sensitive reed switch (42) mounted in the connector (28) attached to the electrical device. The switch is closed when the connectors engage each other by the magnetic field generated by a magnet (62) mounted in the other connector (24').

Abstract: A coin analyzer system and apparatus that provides a detection circuit for comparing a tested coin with at least two different sample coins. Two different sample coins are located in a magnetic field, and the tested coins pass through another region of the magnetic field. In the event the tested coin does not match either sample coin, a rejecting gate forces the tested coin out of the coin chute in a laterally normal direction and into a rejected coin chute. In the event that the tested coin matches either sample coin, the rejecting gate is opened and the tested coin drops through a substantially vertical accepted coin chute. Credit is not extended the tested coin until the coin passes a confirmation sensor, and the determining circuit may be adjusted to vary the credit value extended to at least one of the sample coins. A lockout circuit rejects and prevents a subsequent coin from being analyzed during the time that the circuit is crediting a prior tested coin with multiple credits.
