Patent CA-2089360-A1 (CA)
Inventor: WILSON GREGORY P
IPC: H04B7/005
Filed: 1992-06-19
Abstract: A transmitter (604) of a TDMA cellular telephone (600) includes power control circuitry (100) comprised of variable gain stage (104), mixer (106), bandpass filter (109), RF amplifier (110), and directional coupler (112) in a forward path, and two detectors (116 and 117), four A/D converters (118, 119, 121 and 123), digital controller (120), and D/A converter (126) in a feedback path. In operation, the variable gain stage (104) is responsive to a gain control signal AOCCNT (128) for adjusting a modulated IF signal, which is then mixed in mixer (106) with an RF reference signal to produce the transmit RF signal. The temperature and supply voltage are sampled by controller (120) at the beginning of each time slot. Adjustments in the gain control signal (128) dictated by the sampled temperature and supply voltage are made by controller (120) in each time slot prior to keying the RF amplifier (110). The transmit RF signal is amplified by the RF amplifier (110) to produce the transmit output signal which is coupled by the directional coupler (112) and transmit filter (618) to an antenna (620) for transmission The forward power and reverse power of the transmit output signal are sampled by controller (120) at the end of each time slot. The sampled forward power is used by controller (120) in calculating the value of the gain control signal for the next time slot. If the sampled reverse power or supply voltage exceed respective maximum values, the RF amplifier (110) is dekeyed by controller (120).

Title: Method and apparatus for epidural burst stimulation for angina pectoris
Inventor: BOURGEOIS IVAN
IPC: A61N1/372
Filed: 1991-08-26
Abstract: Method of and apparatus for the treatment of angina pectoris using electrical stimulation within the epidural space of the spinal cord. A sensor is used to trigger stimulation only during periods of activity assumed to be symptomatic. The sensor may measure any of a number of parameters including blood oxygen saturation level or mechanical activity. In the preferred embodiment, a piezoelectric activity sensor is programmed to determine when the level of activity is reached at which angina is expected to occur in a particular patient. This determination is used to trigger an implantable spinal cord pulse generator. Bursts of high frequency stimulation energy are applied by an insulated lead to electrodes implanted in the epidural space at an upper thoracic or lower cervical location. The increased neural activity caused by the stimulation bursts eliminates the pain sensation and allows an equal or higher exercise level of the patient without pain or at a similar pain level. The epidural stimulation does not decrease coronary perfusion at the same exercise level. When sensed body activity decreases below the programmed level, electrical stimulation is inhibited.

Abstract: SYSTEM, METHOD AND APPARATUS FOR GENERATING LARGE JACKPOTS ON LIVE GAME CARD TABLES                 ABSTRACT OF THE DISCLOSURE           A system to generate large (e.g. $1 million) jackpots for live card games such as blackjack is disclosed.          Multiple live card tables are placed in one or more gaming establishments.  A coin acceptor is assigned to each player position on the tables and includes a sensor for determining the presence of a coin to generate a signal indicating that a jackpot side bet has been placed and to correspondingly increase the available jackpot that is being accumulated from the side bets on all tables.  The coin acceptors are mounted directly to the playing tables.  The acceptors have a low profile above the table top and include sloping surfaces to facilitate the insertion and withdrawal of coins from them.          Each coin acceptor communicates with a central computer or processor.  The computer keeps track of jackpot accumulations, deducts winnings therefrom, controls strategically positioned displays to inform players and dealers of the size of the available jackpot or jackpots, and the table includes controls adjacent the dealer position to prevent late betting and pay winning players their jackpots.  To generate the large jackpots, blackjack is played with six full decks of cards, and winning blackjack hands are selected to have the requisite low probability of occurrence.

Abstract: A helicopter engine fuel control anticipates sudden changes in engine power demand during yaw inputs to thereby minimize engine and main rotor speed droop and overspeed during yaw maneuvers. The rate (121, 123) of yaw control (107) position change generates (10) a yaw component (104) of a helicopter fuel control (52) fuel command signal (70).    The magnitude of the yaw component is also dependent upon the rate of yaw control position change (703). The fuel command signal yaw component (104) is overrides (113, 115) when rotor decay rate (209, 217) has been arrested during a sharp left hover turn (216); when the yaw component is removing fuel (239) during rotor droop (238); and when the yaw component is adding fuel (228) during rotor overspeed (227).

Abstract: ABSTRACT OF THE DISCLOSURE          A method is provided for soldering a coil winding to a terminal pin.  A specific quantity of solder is applied onto the terminal pin, the terminal pin having a winding end wrapped therearound.  The solder, for example, can be applied by immersing the pin end into a solder bath having a temperature only slightly above the melting point of the solder.          Subsequently, the solder is melted with a welding torch under a protective atmosphere only at a power and time required to achieve a soft-soldering temperature.  As a result thereof, a soldering free of fluxing agent and without the high thermal stress of a welding is possible.  Other embodiments include placing a ring of solder onto the terminal prior to heating.          Also, a predetermined length of solder wire can be brought into contact with the terminal pin prior to heating.  The invention provides a guide tube device for such a purpose.

Abstract: A novel multi-step process for preparing the (4S &cir& _-enantiomer of 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone in a highly-optically pure form is disclosed. The process involves (1) first esterifying 4-(3,4-dichlorophenyl)-4-ketobutanoic acid with isopropylene or isobutylene to form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-4-ketobutanoate; (2) then reducing the ketobutanoic acid ester obtained in the first step with an asymmetric carbonyl reducing agent to form the corresponding chiral isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoate; (3) then sulfonylating the (4R &cir& _)-hydroxybutanoic acid ester with methanesulfonyl, benzenesulfonyl or p &cir& _-toluenesulfonyl chloride or bromide in the presence of a standard base to yield the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-sulfonyloxybutanoate; (4) next subjecting the 4-sulfonyloxybutanoic acid ester obtained in the third step to a copper-coupling reaction with dilithium diphenyl(cyano)cuprate of the formula  PHI 2Cu(CN)Li2 to effect a stereochemical displacement of the organic (4R &cir& _)-sulfonyloxy group of the (4R &cir& _)-sulfonyloxybutanoic acid ester by the phenyl group of the dilithium diphenylcuprate reagent and so selectively form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoate, and (5) thereafter cyclizing the stereospecific (4R &cir& _)-phenylated n-butanoic acid ester in the presence of a protic or Lewis acid catalyst to finally yield the desired (4S &cir& _)-4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone compound in a highly-optically pure form. The latter compound, which is a novel (4S &cir& _)-enantiomer per se, has utility as an intermediate that ultimately leads to pure c &cir& _i &cir& _s &cir& _-(1S &cir& _)(4S &cir& _)N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine (sertraline), which is a known antidepressant agent. The aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoic acid, as well as their corresponding (4R &cir& _)-methanesulfonyl, (4R &cir& _)-benzenesulfonyl and (4R &cir& _)-p &cir& _-toluenesulfonyl derivatives, are also novel compounds, as are the aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoic acid as well as the aforesaid acid per se. These novel chiral compounds are all useful as key intermediates in the overall process of the present invention.
