Abstract: Printed circuit boards with sensor controlled illumination units and end-to-end connection capabilities. For example, a lighting element, sensor/detector, and computational control element are implemented on a printed circuit board. The printed circuit board also includes end-to-end connection terminals that allow multiple printed circuit boards to be operably coupled together in an end-to-end manner. This provides a scalable system that can be modularized to a base unit for installation in various packages, orientations, or environments.

Abstract: A laser level assembly is provided. Various methods of managing communications between laser levels and detectors are provided. In one or more methods, upon receiving a selection of a communication channel the laser level emits a laser with certain characteristics, such as by adjusting the rotation speed, rotational direction, and/or emitting the laser in a repeating on/off pattern.

Abstract: A laser marking/imaging system including a passively Q-switched microlaser having a saturable absorber which upon reaching an energy threshold emits a pulse of light through an optical output. The microlaser is electrically connected to circuitry which provides power to the microlaser, and has a simmer mode and a lasing mode. In the simmer mode, power provided to the microlaser is maintained at an energy level below the energy threshold, and in the lasing mode, power provided to the microlaser raises the energy level of the microlaser above the energy threshold. A guidance mechanism can direct the pulse of light from the optical output along a path toward an image receiving target when the microlaser is in the lasing mode.

Abstract: A detonation control system for a fuel injected, spark ignition two-cycle engine utilizes a linear series of engine knock signals and a programmable microprocessor to provide a non-linear series of stepped increases in the fuel injection pulse width to the engine effective to substantially reduce or eliminate engine knock. If desired or necessary, the system may also be utilized to provide a non-linear series of stepped increases in spark ignition retard to further reduce or eliminate engine knock. The non-linear stepped increases in the control parameters have been found to effectively control detonation without adversely affecting engine performance and efficiency.

Abstract: In a marine drive having a wiring harness (14) connected between the engine (2) and the helm (8), an alarm sensing module (26) is connected to the harness (14) and provides a warning of one or more abnormal engine conditions, without altering the existing wiring harness or adding wires thereto. A temperature switch (30) and an oil pressure switch (32) are provided at the engine, and the sensing module (26) is connected to the engine temperature gauge (10) and engine oil pressure gauge (12) at the helm. The module activates an alarm (28) in response to high engine temperature or low engine oil pressure.
