Abstract: The present invention is an alarm clock device which programmably and automatically coordinates the movement of one or more electric toy trains, or the like. The present invention alarm clock preferably triggers the movement of an electric toy train when a pre-set alarm time is reached. The alarm clock device comprises at least one base that defines an elongated substantially non-linear track for regulating the movement of a toy train. The traveling speed of the train is preferably regulated by a voltage varying device, such as a transformer, that is attached to the track and also coupled to a manually adjustable speed controlling member within the alarm clock. The movement of the train is preferably accompanied by applicable audible sounds that correspond therewith. The duration of movement may be programmed manually and may be adjusted in any variety of ways.

Abstract: A rearview mirror assembly is provided for a vehicle which incorporates a self-contained magnetic field sensor in the mirror housing. When mounted to a fixed pivot point in a single ball mounting bracket, the mirror housing pivots around the magnetic field sensor. When the magnetic field sensor is mounted within the mirror housing either to the housing or to the mirror, compensation for the rotation position of the mirror about a vertical axis is provided by an empirically predetermined compensation value whereby direct reading of the angle is adjusted by a processor or by mechanically mounting the field sensor at an angle representative of the compensation value. Other ways of rotation compensation are also disclosed. Compensation for tilt about a horizontal axis is provided by an elliptical compensation algorithm in a microprocessor.

Abstract: A radio wave receiving signaling device includes an antenna (22) having a coil (22a). An electrically capacitive buzzer (21) is activated by alarm output device (AO) to generate sound when the receiving antenna (22) receives a sound generation instructing signal. The buzzer (21) and all or part of the coil (22a) of the receiving antenna (22) are connected to form a booster circuit to raise a voltage to be applied to the buzzer (21) by a resonance function.

Abstract: An arrangement allowing a definite and reliable determination of a load resistance connected to the secondary side of a transformer includes devices, which measure exclusively the inductance of the transformer on the primary side and signal a load malfunction in the case of deviation from a predefined value.

Abstract: When an automotive vehicle travels to come near one of rest points set in advance (S4), when the abnormality of the driving condition of the driver, or when a continuous driving time period over which the vehicle is continuously driven becomes equal to or longer than a predetermined time period T1, the driver is instructed to take a rest (step S14). When the driver is instructed to take a rest at a point other than the scheduled rest points, a suitable rest point is searched for (S13) to instruct the driver to take a rest there, and subsequent ones of the scheduled rest points are changed (S17).

Abstract: An electronic pump switching system comprises a water sensor coupled to a comparator which generates an output signal when water is sensed. The comparator output is coupled to a timer, which is initiated for a predetermined period by the comparator output signal. The timer is coupled to a switch which activates a coupled device, such as a pump, for the predetermined period. The continued presence of water at the sensor at the end of a predetermined period causes the timer to time a new predetermined period, whereby the coupled device remains activated. The sensor may be formed from a pair of electrodes arrayed as a voltage divider. The voltage divider action may additionally serve as a discriminator, allowing timer operation to be tied to the detection of water, as opposed to petroleum products, such as fuel.

Abstract: A tank display system for a tank filled with fuel, the tank being divided into a main tank and a supplementary tank, has a level limit switch which responds when the main tank is almost empty. If the switch gives off a signal, then a valve is opened, allowing fuel to flow from the supplementary tank into a flood cup of the main tank. Furthermore, this signal activates a unit for detection of fuel consumption, which unit calculates the remaining volume of fuel in the supplementary tank, which volume decreases as a result of the consumption of fuel. As starting volume for the calculation, the completely filled supplementary tank is used. The precise remaining volume of fuel is displayed.

Abstract: A fork lift truck capacity monitor or alerting device informs operators of the weight on the forks and fork height and alerts operators whenever truck speed is above creep with the forks raised above a collapsed height or whenever the forks are raised above a recommended height for a given load. The alerting device includes a control circuit that receives inputs from a speed sensor, a fork height sensor and a weight sensor and reads a memory storing data correlating load weights with maximum recommended fork heights. A truck icon is displayed on a display panel. A plurality of height zone lamps representing the weight of the load on the forks are arranged in a vertical column over the truck icon and selectively illuminated according to the load on the forks.

Abstract: A warning apparatus for an injection molding machine includes a detection device for detecting an operation performed by an operator of the injection molding machine; a warning section for warning the operator in response to a detection signal from the detection device; and a cancellation section for canceling the warning when the operator correctly operates the injection molding machine. When there is a possibility that an operator incorrectly operates the injection molding machine, a warning is generated by the warning section. Therefore, the operator is prevented from incorrectly operating the injection molding machine. Thus, breakage of the mold unit is avoided. Further, since the cancellation section is provided, the operator does not have to perform any operation for canceling the warning, so that work efficiency is improved.

Abstract: An optical fire detector employs two or more sensors operating a different spectral bands. The spectral bands are selected to have approximately coincident cut-off wavelengths in order to make the detector's ability to positively identify a fire more uniform over its field of view. The use of three overlapping spectral bands provides the detector with enhanced detection capabilities for large, hot fires that behave like black body radiators.
