    Abstract: Synchronisation electronique d'un moteur et dispositif de distribution (10) servant a commander l'injection de combustible et/ou l'allumage par bougie d'un moteur a combustion interne. Un vilebrequin (11) du moteur fait tourner un corps rotatif (12) possedant une pluralite d'elements en saillie (19-22) disposes radialement, et un detecteur simple (23) de reluctance du vilebrequin est utilise pour produire des impulsions (24) en reponse au passage de ces elements en saillie et produire ainsi un signal (24) en fonction de la position du vilebrequin. Un arbre a came (13) du moteur fait tourner un corps rotatif (14) avec des elements en saillie (15, 16) disposes radialement et tournant a la moitie de la vitesse du vilebrequin, et une paire de detecteurs (17, 18) d'arbre a came produisent des signaux (25, 26) en reponse au passage des elements en saillie de l'arbre a came, ces signaux etant indicatifs de la position de l'arbre a came. Les signaux (24, 25, 26) produits par les detecteurs de vilebrequin et d'arbre a came sont recus par des circuits (30-35) qui produisent un signal (27) de reference de vilebrequin possedant des transitions de polarites alternees predeterminees a des positions specifiques de la rotation du vilebrequin et produisent aussi des signaux (60-63) d'identification du cylindre qui sont indicatifs de la position angulaire de rotation du corps rotatif de l'arbre a came. Ces signaux (27, 60-63) sont ensuite utilises par un dispositif electronique conventionnel de commande d'injection de combustible et/ou d'allumage par bougie pour commander le fonctionnement des cylindres du moteur selon une sequence correcte et au moment opportun.

    Abstract: Polycrystalline silicon (84) is deposited on the interior surface of a shaped container (40). The silicon is deposited by reacting hydrogen (31) and a silicon bearing gas (30) in the presence of a high pressure plasma (22). The silicon body is separated from the shaped container by utilizing thermal expansion shear stress.

    Abstract: A decoder for use with a compatible AM stereophonic signal of the form (1+L+R) cos (Wct + 0) utilizes an amplifier (26) and a feedback loop from the amplifier output to control the output of a multiplier circuit (28 or 36) which is one input to the amplifier. The amplifier output is thus forced to become the required correction factor used in deriving the stereo program signals from the AM stereophonic signal.

    Abstract: A high frequency divider suitable for use in a frequency synthesizer using a dual modulus prescaler (10) and two counters (30, 40) to achieve high speed and low current drain. The input signal is alternately divided by one of the two moduli in the prescaler and then alternately divided by one of the two counters. Each of the two counters is reset while the other is counting thereby reducing circuit complexity and increasing circuit speed.

    Abstract: A peak beam current leveler for use in a television receiver system which is responsive to the magnitude of the beam current supplied to the cathode of the cathode ray tube (CRT) exceeding a predetermined peak level to adjust the cathode peak beam current accordingly. The cathode beam current is supplied by a gain controlled video amplifier (38) to the cathode through the base-emitter junction of a transistor (56) The collector electrode of the transistor is connected with a resistor (58) for providing a voltage level proportional to the peak beam cathode current. A comparator circuit (70-80) is utilized to provide a gain control signal that controls the gain of the gain controlled video amplifier such that the higher the beam current the more gain reduction that occurs. Thus, the level of the peak current is automatically reduced to maintain good focusing of the display on the CRT.

    Abstract: A multifrequency tone receiver (100) for detecting simultaneous tone signals in a sampled digital signal. The tone receiver (100) includes a microprogrammed sequence controller (101 and Fig. 3B), a time-multiplexed digital filter (102 and Fig. 3C) and a signal processing microcomputer (103 and Fig. 3A). For each sample of the digital signal, the sequence controller (101) is programmed to time multiplex the digital filter (102) for performing three cascaded second order filtering operations (two bandpass filter operations and one low pass filter operation as shown in Fig. 2) for each of six tone signals to provide corresponding energy estimates and one additional filtering operation to provide a total energy estimate. The signal processing microcomputer (103) processes (per flowchart in Fig. 7) a number of sets of the seven energy estimates and provides an indication when a multifrequency tone pair has been detected. The digital filter (102), when enabled by a filter start signal from the sequence controller (101), asynchronously performs a signal multiplication-like filtering operation to implement each second-order filter, and provides a filter done signal upon completion of the filtering operation. Full-wave rectifying capability is provided during low pass filtering operations by logically complementing (gate 361 in Fig. 3C) the digital filter input signal. Limit cycles may be suppressed in the digital filter output signal by rounding the output signal and clamping (gates 365-368 in Fig. 3C) positive and negative overflows to the largest allowable positive and negative signals, respectively. The tone receiver (100) may be advantageously utilized in a PCM communication system for detecting multifrequency tone signalling used for dialing and supervisory control. Moreover, the inventive tone receiver (100) may be adapted to receive many different types of tone signalling simply by changing firmware (Tables I and IV) therewithin.

    Abstract: A single slope analog to digital converter uses a DAC (21) to trim the discharge current of a capacitor (10) during calibration thereof. A method of calibrating the analog to digital converter is provided which iterates required steps to obtain a correct current setting within a short period of time. The analog to digital converter discharges a capacitor (10) through a high impedance to obtain a linear discharge. The time to discharge the capacitor (10) appears in a counter and is indicative of the voltage across the capacitor (10) at the beginning of the discharge period once the analog to digital converter has been calibrated.

    Abstract: Thick film capacitors with screened electrodes can not be laser trimmed without damage to the dielectric. To solve this problem a thick film capacitor, with a first electrode (12), at least one dielectric layer formed from paste (14, 16) and a thin second electrode (18) are formed on a substrate (10). The second electrode (18) is formed from an organo-metallic paste including gold atoms which electrode has a thickness of about 1 micron. This thin electrode (18) can be trimmed by a low energy laser beam (20).
