Abstract: An improved technique for a laser rangefinder includes a pulsed laser sending out a repetition of light pulses and the received signal (light pulse and noise components combined) being analyzed by continuous averaging of successive received signal discrete time sequences, each sequence beginning with the onset of transmitted laser light. Also, a circuit generates high potentials for the laser diode driving circuitry that simultaneously drives the laser diode, having at least one of several beneficial characteristics: It is conveniently synchronous with the light pulse send/receive process to reduce the effects of noise on the receive section. It is energy efficient in converting low battery potentials to higher voltages. Finally, it utilizes a minimized number of components, leading to high product economy.

Abstract: An electronic inclination sensor is provided for the determination and display of surface inclination and the direction of such inclination. The information regarding the inclination and direction of inclination can be displayed such that an end user can readily and easily comprehend and use the information without additional interpretation. Further, when the inclination is displayed in decimal values, a large range of inclination angles can be displayed with significant accuracy.

Abstract: A golf ball and golf ball search receiver is described. The golf ball includes a transmitter and the search receiver includes a receiver. The golf ball may be activated by an accelerometer that causes the transmitter to produce an RF signal across a predetermined frequency band for a duration of time, which may be determined by a timer. The transmitter modulates an audio signal and transmits the modulated signal within an output band of the transmitter. The receiver tunes to a narrower band thereby receiving and demodulating a fraction of the transmitted signal. The receiver's input band halves an input bandwidth set to coincide with a fraction of the output band, thereby alleviating adverse effects due to variations in transmitter and receiver components, as well as adverse effects due to localized noise within the output band. Additionally, relative positioning of the receiver's input band may cycle across the transmitter's output band to further mitigate the adverse effects of localized noise.

Abstract: A device for testing the rebound quality of a golf ball is described. The device includes a substrate of hard, dense material with a level, flat upper surface, the substrate being attached to an accelerometer that is capable of sensing the impact of a golf ball dropped onto the substrate's upper surface. In turn, the accelerometer is connected to a pulse period measuring module capable of determining the period of time between successive impacts as the golf ball freely and repeatedly bounces against the substrate. Further, a computational module capable of determining from three or more successive bounces the mechanical loss the golf ball experiences on each bounce. Three successive impacts against the substrate result in two time period measurements. The first time period is that which elapses between the first and second impacts and the second time period is that which elapses between the second and third impacts.
