Abstract: A engine kill switch system has a transmitter and receiver which are linked through specific transmitted codes within a frequency. The receiver is mounted directly on the boat and wired to an engine kill switch, maintaining the switch in the closed position as long as a signal is received from all of the activated transmitters. Once the transmitter signal is unintentionally deactivated, the receiver shuts down the engine. A range adjustment allows the separation distance between the transmitter and receiver to be changed, dependent upon the size of the boat and end use. A strobe and audio warning can also be attached to the receiver and activated simultaneously with, or as an alternative to, the deactivation of the engine. Automatic transmitter activation and deactivation can be provided through storage ports tied to the receiver. The transmitter is a battery powered remote device carried by a user. The transmitter has a programmed unique code recognized by the receiver.
Abstract: An apparatus and method for current sharing among multiple power supplies is disclosed. The output current of each power supply is compared in an amplifier which produces an output signal. This signal controls a transistor used to enable or disable current flow on a SENSE line in a particular power supply. By controlling the SENSE line, the output current of each power supply is adjusted to roughly equal levels. The combined current is thereby the combination of approximately equal shared outputs of each individual power supply. The current share of each individual power supply is offset by a predetermined level to prevent a race condition in the initial power-up phase.
Abstract: A logarithmic current measurement circuit for operating upon an input electric signal utilizes a quad, dielectrically isolated, well-matched, monolithic bipolar transistor array. One group of circuit components within the circuit cooperate with two transistors of the array to convert the input signal logarithmically to provide a first output signal which is temperature-dependant, and another group of circuit components cooperate with the other two transistors of the array to provide a second output signal which is temperature-dependant. A divider ratios the first and second output signals to provide a resultant output signal which is independent of temperature. The method of the invention includes the operating steps performed by the measurement circuit.
Abstract: A power-on reset circuit, which includes a fully symmetrical flip-flop in the path of propagation of the reset pulse. The two outputs of the flip-flop are combined together, so that propagation of the pulse can occur as soon as the flip-flop has stabilized in either of its possible stable states. However, a feedback connection cuts off any further propagation through this path once a power-on reset pulse has been issued. Thus, this circuit is extremely stable, and will not issue further power-on reset pulses even if hit with a very severe power glitch.

Abstract: A transmitter with controlled switches for use in a process for the generation of transmission current signals in an alternating current distribution network is connected to the supply network. When operated, this transmitter generates a series of current impulses. The moments in time of the generation of these current impulses and/or their duration are so chosen that the resulting transmission signal corresponds at least approximately to a desired theoretical signal. The transmitter contains at least two energy storages or energy storage devices and at least two switches for controlling the energy exchange between the two storages. These switches are so controlled that the exchange current flows through the mains, whereby the aforesaid current pulses are generated.It is thereby possible to use substantially only loss-free elements for the transmitter.
Abstract: A method and apparatus are disclosed for controlling an off-line dc power supply circuit including a printed circuit board. The power supply circuit comprises a source of unregulated dc input power and a power transformer which separates the circuit into a primary side and a secondary side. An error amplifier compares an output dc voltage generated at a secondary winding of the power transformer to a reference voltage to generate an error signal representative of the difference error therebetween. The error signal is coupled from the secondary side of the power supply circuit to the primary side of the power supply circuit by means of a capacitor formed from traces on opposite sides of the printed circuit board. A solid state switch selectively connects the unregulated dc input power to a primary winding of the power transformer to regulate the power supply circuit in the primary side of the circuit in response to the error signal which is generated in the secondary side of the circuit.
Abstract: A system for controlling the operation of a load circuit coupled to an AC power distribution circuit includes an encoder which may be mounted in a wall switch box and coupled to a single conductor of the AC power distribution circuit for imposing thereon control signals by lengthening the zero crossings of the AC voltage.

The encoder may be disconnected from the AC power distribution circuit, in which case the load circuit may be controlled by an external condition responsive device, such as a passive IR sensor. Visible light-responsive means may be provided for disabling the IR sensor during the day. The load circuit and the decoder can be turned off from the encoder location.

Abstract: The system comprises a central control unit and a plurality of remote units connected to the control unit by a single, common, transmission link. This link acts simultaneously as a signalling link and as the electrical voltage supply line for the remote units. The control unit transmits electrical control signals to the remote unit by superimposing trains of pulses on the supply voltage that is fed via the transmission link to the remote units. Each remote unit is arranged to count the control signal pulses appearing on the line and to activate one or more controlled devices when the number of pulses counted corresponds to a unique number associated therewith. A first type of controlled device is constituted by sensor means arranged to monitor a physical quantity and to output, when activated, related electrical information signals indicating to the control unit the value of the monitored quantity; the information signals take the form of frequency modulation of the current flowing in the transmission link.
