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.

Method and apparatus for measuring the surface of a golf green

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. In this embodiment the pins are inserted to the first board and external connections to the matrix are made via plug-end connectors at the fourth board. Connections between the first and fourth boards are provided by jumper rods extending through aligned jumper holes defined in each board. Housekeeping holes are provided at the matrix periphery to jump signals between the first and second boards and between the third and fourth boards.

Cross-connect system

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.
