Abstract: A golf green measuring device according to the present invention includes a plurality of spaced apart rails attached to an enclosed structure. The structure includes a control unit including a microcontroller, circuitry, a battery, a display and a level indicator. The rails include infrared emitters and detectors that sense a golf ball traveling through the enclosed structure. The microcontroller measures the elapsed time the golf ball travels between a pair of detectors disposed at the rail front end and the elapsed time the golf ball travels between another pair of detectors disposed at the rail rear end. The change in velocity or deceleration of the golf ball is determined based on the measured time intervals and converted into a speed value. The computed speed value is displayed on a device display. The device may include an optional printer to provide a hardcopy of the measurement.

Abstract: A telecommunications system provides a call transfer function while user-A is involved in two independent calls: one with user-B and one with user-C. The call transfer by user-A is initiated by sending a message to the long distance carrier switching office. In the switching office, both independent calls are identified as part of the transfer request. The switching office then requests the call transfer function by sending a message to the network control system for the validation of the transfer. After the network control system determines allowability of the transfer, the call between user-B and user-C is connected, while user-A and user-A's customer premise equipment is disconnected from user-B and user-C.

Abstract: A switching matrix includes at least two parallel circuit boards each having plural conductive traces and multiple matrix holes therethrough arranged to permit traces on one board to be connected to traces on the second board. Connection is achieved by means of a flexible non-conductive circuit jumper pin having a resilient conductive sleeve arranged to extend between an aligned pair of holes in the two boards. The holes are conductively plated to define female contacts to radially compress the conductive sleeve. Circuit jumper pins may be moved between different matrix positions manually or by a pick and place mechanism controlled from a remote location. In one embodiment, serving as a telephone cross-connect switch, connections are made in pairs, therebeing four circuit boards and two conductive sleeves on each pin, each sleeve interconnecting a pair of traces on a respective pair of boards.

Abstract: A monitor system for ensuring that passengers have exited a vehicle such as a school bus is activated when the ignition of the vehicle is shut off. A buzzer sounds in response to ignition shut off, alerting the driver to disable the alarm system. If he does not do so within a predetermined period of time an alarm is actuated. A switch for disabling the alarm system is located at the rear of the bus to require the driver to walk to the rear of the bus to disable the alarm. This, in turn, requires the driver to observe whether or not any children remain in the bus.
