    摘要: A diesel timing light includes a flash circuit for flashing a xenon lamp in response to ignition events sensed by a knock sensor. A trigger circuit enables the flash circuit only in the presence of an enable signal, which is generated by a sensing circuit immediately before the ignition of the no. 1 cylinder. The sensing circuit includes a visible laser source which illuminates a patch of reflective tape on the engine flywheel just ahead of a timing mark corresponding to engine top dead center. The tape reflects the visible laser light to a sensor which generates the enable signal. The trigger disables the flash circuit immediately after the flash triggered by the first ignition event after the enable signal. LED indicators indicate when the photosensor is detecting the reflected beam and when the knock sensor is detecting ignition events.

    摘要: A torque-angle wrench is provided with a handle for applying torque, such as to a fastener or bolt, through a tightening angle, at a rotational angular velocity. A piezoelectric gyroscopic sensor device including circuitry for vibrating an oscillating body is coupled to the wrench. As the wrench is rotated through the tightening angle, its rotational angular velocity causes the vibrating body to alter its direction of vibration. The new vibrating pattern is sensed and converted, by appropriate sensing circuitry, into an electrical signal proportional in intensity to the rotational angular velocity of the wrench. The electrical signal can be electronically processed by appropriate conversion and display circuitry to provide a visual indication of the tightening angle. Such conversion and display circuitry can be integral with the wrench or as part of an adaptably coupled meter non-integrally connected to the sensor device.

    摘要: An electrically powered impact tool has a removably mountable battery pack which includes an acoustic detection circuit for detecting sounds generated by the impact mechanism in use and, in response to such detection, starts an adjustable time period, at the end of which a relay is actuated for disconnecting the battery of the battery pack from the tool motor for a predetermined time period. This serves as a torque-limiting mechanism where the tool is a torque-applying tool. The time period is adjustable by a dial on the battery pack housing and the control circuitry may be selectively powered through a switch on the battery pack housing.

    摘要: A charge maintenance system for a lead-acid battery includes a charger, a voltage monitor, and a load/switch series combination, all connectable in parallel across the battery terminals, the switch and the charger being under control of a microprocessor. The battery is initially loaded for a predetermined time period, or until the battery voltage drops below an absolute minimum reference level during a loading cycle, and the system stores the lowest battery terminal voltage occurring during the loading cycle. After a predetermined delay following the loading cycle the charger is activated to charge the battery until it reaches a maximum charge level. Then, if the stored lowest battery voltage level is below a predetermined reference level, the loading/charging routine is repeated, otherwise it is not and the battery is considered good. If the stored lowest battery voltage level remains below the threshold for ten consecutive loading cycles, the system indicates that the battery failed the test but could be subject to retest. If the stored lowest battery voltage level is below an absolute minimum reference voltage level after three consecutive loading cycles, the system indicates that the battery is bad and should be discarded.

    摘要: A battery pack has a pair of input/output terminals adapted to be connected across a source of charging voltage, and a lead-acid battery connected across the input/output terminals. A Zener diode is connected in series with a resistance across the input/output terminals, the resistance forming part of a trigger circuit for triggering an alarm signal to actuate a visible and/or audible annunciator when the charging voltage exceeds a threshold level. In one embodiment the trigger circuit is an IC comparator having one input connected to a reference voltage drive from a voltage divider connected across the input/output terminals, and the other input connected to the trigger voltage across the resistance in series with the Zener. In another embodiment the trigger circuit includes a pair of transistors, one being turned ON by the trigger voltage and in turn ON the second transistor to produce the output signal and provide a feedback to latch on the first transistor.

    摘要: An inductive pickup assembly senses the electromagnetic fields of plural ignition elements of an automotive engine, access to which elements is prevented by associated engine housing structure. The pickup assembly includes a frame having a flat platform on which multiple sensors are mounted, each sensor comprising an electromagnetic pickup coil with a magnetizable metal core integral with a magnetizable metal shield plate which covers one end of the coil. The frame has a support member with depending feet having apertures which mate with fasteners on the housing structure to serve as a template for accurately locating the pickup assembly on the housing structure.
