Abstract: A directional starting spring which ensures that an AC synchronous motor is rotating in the proper direction is disclosed. The AC synchronous motor includes a circular magnet rotating in "synch" with the frequency of the alternating current. The magnet rotates a worm gear attached to the center on its axial face. This worm gear drives a second worm gear positioned perpendicular to the first worm gear. The second worm gear drives a series of gears which display the elapsed time. Attached to this second worm gear is the directional starting spring. If the motor is rotating in the proper direction the spring contacts the housing of the meter and slides on the second worm gear. If the motor is rotating in the wrong direction the spring contacts the axial face of the magnet stopping the rotating magnet and pushing it in the proper direction.

Abstract: A safety belt assembly of the present invention measures the amount of force exerted on the assembly and also the point in time when a force was exerted on the assembly. The assembly includes a first and second member associated with one another, mechanism associated with the first and second members for resiliently restraining relative movement and movably retaining said members with respect to one another; a mechanism responsive to relative movement of the first and second members for enabling a measurement of force and indicating a point in time when a force was exerted on the assembly; and a mechanism for securing the assembly to a safety belt and/or a buckle or anchor.

Abstract: The circuit comprises an elapsed time indicating meter and a silicon-controlled rectifier, used to supply power to the meter, connected in series across the circuit's first and third terminals. Additionally, the circuit includes a small resistor connected between the second and third input terminals, that is, connected in series with the a.c. device. This small resistor receives the current through the a.c. device and the voltage across the small resistor is indicative of the operational state of the a.c. device. A variable potentiometer is connected full scale across the small resistor and the variable voltage is amplified by a common-base transistor. This amplified voltage is both rectified and filtered, serving as the SCR's gate terminal input for triggering the SCR.The potentiometer is adjustable to allow the SCR to trigger in either one of two conditions.

The assembly comprises a first and second member; a mechanism coupled with the first and second members which provides incremental movement of the members; a resilient biasing member in communication with the members for maintaining the members in a first relaxed position; the resilient biasing member enabling the measurement of an amount of force exerted on the assembly; a mechanism for indicating when a force is exerted on the assembly and a mechanism for securing the assembly to a belt and buckle.

Abstract: A suspended-line-and-clock trail monitor improved (1) by anchoring the monitor-end of the trip-line in such a manner that when a crossing animal increases line tension beyond a predetermined threshold, stored line pays out to and is carried by the animal, thereby recording its precise path and direction of travel across a line of almost any length and (2) by introducing a resettable, lightly triggered actuator between the line and the clock thereby providing reliable operation from a mass-produced, low-cost, general-purpose digital clock in place of the usual stop watch, even with a line of light sewing thread. Such thread cost effectively combines sufficient line length for long runs with good portability.

Abstract: The electromagnetic transmission in an interference-laden environment of events defined by the time of their occurrence is accomplished by repeatedly generating, at equal intervals after occurrence of the event, signals representing the occurrence of the event. An event which must be defined by the time t.sub.e at which it occurs triggers a switch which in turn triggers a time base whose signal is sent to a counter. The counter produces at its output a sequence of pulses which are coded in a coder. The code indicates for each pulse the deviation in time .DELTA.T.sub.i which separates it from the time at which the event occurred. The sequence of pulses is sent electromagnetically to a receiver via a transmitter. The first interference-free pulse received is processed by a decoder which provides the value .DELTA.T.sub.i to an arithmetic unit. The arithmetic unit subtracts the value .DELTA.T.sub.i from the time of day t.sub.h to obtain the time of day t.sub.e of the event.

Both the external station and the portable information device are provided with a central processing unit, a memory device, a display device, an input device and a power supply. The portable information device and the external station can be coupled together by an electrical or optical interface to permit transfer of programs from the external station to the portable information device and exchange of data therebetween.

Abstract: A fluid delivery monitor having a flow sensor, accumulator for recording the duration of sensed flow, a code device to display the contents of and reset the accumulator upon entry of a preselected sequence, and a fluid sensor to disable the accumulator for sensed conductive fluid. The flow sensor is a pressure-sensitive switch recessed in a radial port and a vane substantially covering the port protects the switch from tampering and directs fluid toward the switch.

Abstract: An indicating electronic timer useful for timing processing events and for controlling a process measures the elapsed time from a moment at which a process variable attains a predetermined value and produces a signal which varies in accordance with the elapsed time. During a timing operation, the signal is displayed on a display device which normally displays the process variable, and may be such that the display device indicates the percentage of a predetermined time interval which has elapsed. The timer may be conveniently implemented with relatively inexpensive integrated circuits, such as a variable oscillator, binary counters, and D/A converters.

Abstract: A watch/calculator is disclosed which employs a hold circuit to hold clock incrementing pulses when data from the clock is transferred to calculator circuitry or an arithmetic operation is performed on the data. When the time data is returned from the calculator circuitry to the clock circuitry or the arithmetic operation is completed, the hold circuit releases any held incrementing signal so that an increment signal is not lost, even when the time data is momentarily out of the clock circuitry in the calculator circuitry or other operations are being performed on the time data. Thus, when the time data is returned to the clock circuitry or the operation is completed, the data is incremented or updated as it would have been normally.

Abstract: A system for automatically time setting and message setting or programming of a cased digital watch or a watch module and including both an external setting unit and a serial interface control circuit inside the cased digital watch. The system in accordance with the invention is compatible with either watches that require time setting or watches that require both time setting and message programming and is applicable to any type of manually controllable watch. The time and message set system has a data entry unit that includes a keyboard, a display, a reference time module, a memory, a light source such as a light emitting diode or an LED array as an output and a processor which provides central control of the other functional units. The LED array output supplies coded messages to a light or energy responsive device or phototransistor in position under the face of the watch. The watch includes a novel circuit for responding to the phototransistor and provides time setting and message setting.
