Title: Optimized nerve fiber stimulation
Inventor: THOMSON THOMAS H
IPC: A61N1/36
Filed: 1986-11-04
Granted: 1991-08-20
Abstract: OPTIMIZED NERVE FIBER STIMULATION    Abstract of the Disclosure Optimization of nerve fiber stimulation to substan-tially increase the activity of the then selected nerve fibers is disclosed, with optimization being achieved through utilization of electrical pulses that are caused to occur in a predetermined pattern with respect to polarity, spacing, frequency and duration so as to interact with the electro-neurophysiological characteristics of the particular nerve fibers then to be electrically stimulated.  Bi-phased pulse pairs are repeatedly generated and applied to the nerve fibers to be stimulated with the first pulse of each pulse pair being a positive polarity pulse causing the nerve to be set into the refractory period, while the second pulse of each pulse pair is a negative polarity pulse that is made to occur substantially at the end of the refractory period for the particular nerve fibers then being stimulated to thereby excite those nerve fibers, and the pulse pairs are repeated at a rate based upon the timewise occurrence of the enhanced excitability condition of the nerve fibers then being stimulated.

Abstract: SYNCHRONIZING CLOCK SIGNAL GENERATOR     ABSTRACT OF THE DISCLOSURE         A synchronizing clock signal generator has, in combination with a PLL circuit, a signal delay circuit for delaying a reference input signal by a prescribed time and issuing a reference signal, and a shift register receptive of the reference input signal and a clock signal which is an oscillation signal from a voltage-controlled oscillator or a signal produced by frequency-dividing the oscillation signal by an integer, for issuing a comparison signal in synchronism with the clock signal.  The comparison signal and the reference signal are compared in phase.  Even if the reference input signal is not a pulse signal of a fixed frequency, a synchronizing clock signal can be reproduced, insofar as the reference input signal is a pulse signal with its polarity inverted at the time of a multiple of a prescribed natural period.

Abstract: (57)  Abstract:          The invention concerns a method and an apparatus for cleaning freight containers and for treating and circulating the cleansing liquids. According to the invention, an aqueous soda-containing solution is used as cleansing liquid, volatile organic substances, if any, are separated from the cleansing liquid in a separation unit (4) and in a distilla-tion unit (5) and the liquid obtained is then treated with lime and carbon-containing fly ash in a mixing unit (8). The impurities of the cleansing liquid are sorbed to the activated carbon and precipitate onto the calcium carbonate. The slurry is filtered and the solid material retained in the filter (9) is further fed to a combustion unit (7). Flue gases formed in the combustion unit (7) are treated with the filtrate, whereby sodium hydroxide in the filtrate is trans-formed into carbonate form, and may be used as new cleansing liquid in combination with makeup chemicals. The volatile organic compounds are used as fuel in the combustion unit. The invention provides an integrated process, in which waste products may be used for treating cleansing liquids.

Abstract: VEHICLE ENGINE REMOTE START/STOP  CONTROL AND PROTECTIVE SYSTEM            ABBTRACT     This invention is a remote start/stop and control system for an internal combustion engine of an unattended vehicle operating with a  fuel injection system. The engine starts to activate remotely when a car receiver,  upon receiving a start command signal  from a momentary start/stop-push button integrated in a portable transmitter, energizes first the starter motor solenoid through a parallel starter auxiliary circuit. If certain conditions are met, a parallel ignition auxiliary circuit will connect the car battery to the ignition system. The engine stops to activate remotely when the car receiver, upon receiving a stop command signal from the portable transmitter, disconnects the parallel ignition auxiliary circuit. A latch, of a maximum duration of seven seconds, is located between the battery and the starter motor solenoid to control the rotation time of the starter motor. A timer is used to control the continuity of the parallel ignition auxiliary circuit. The duration of the timer is variable and manually set. A hood switch is provided in the car receiver circuit as interlock in the parallel starter auxiliary circuit.
