Abstract: The embodiments described herein provide systems and methods that can improve performance in scanning laser devices. Specifically, the systems and methods utilize a non-uniform variation in optical expansion coupled with variation in the energy level of laser light pulses to provide an improved effective range over a scanning area. In general, the improved effective range varies over the scan field, with relatively long effective range in some areas of the scan field and relatively short effective range in other areas of the scan field. This varying range over the scan field is facilitated by expansion optics that provide a non-uniform variation in optical expansion for laser light pulses relative to position along a first axis in the scan field and by a light source controller that varies the energy level of the laser light pulses according to position along the first axis of the scan field.

Abstract: A light detection and ranging system modulates laser light pulses with a channel signature to encode transmitted pulses with channel information. The modulated laser light pulses may be scanned into a field of view. Received reflections not modulated with the same channel signature are rejected. Multiple light pulses of different wavelengths may be similarly or differently modulated.

Abstract: A scanning laser projection system includes a virtual protective housing circuit to automatically reduce power levels of visible laser light pulses when necessary to render the laser projection system eye-safe. IR laser light pulses are scanned out in front of visible laser light pulses in a field of view, and emitted power of visible laser light pulses is modulated based on attributes of reflections of the IR laser light pulses.

Abstract: A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.

Abstract: A scanning laser projector drives laser light sources with waveforms for higher efficiency. Optical light power values for pixels are mapped to amplitude/duration pairs. Laser diodes are driven with electrical currents having the amplitude for time period specified by the duration. For increasing optical light power values, amplitude values are increased, and then durations are increased.

Abstract: A zero turning radius mower has a dual hydrostatic pump with right and left pump arms. A linkage between the pump arms and a pair of control levers destrokes both sides of the pump simultaneously if engine speed drops below a specified value. The linkage allows each pump arm to have a first stroke range if the engine powering the pump is above the specified value, and a second smaller stroke range if the engine powering the pump is below the specified value.

Abstract: A platform trailer includes a load carrying main frame and an elongated loading deck supported by the main frame and defining a generally planar surface upon which cargo may be loaded. An elongated side rail is attached to at least one of the loading deck and the main frame so that the side rail is disposed along a longitudinal edge of the trailer. The side rail defines an upwardly opening channel extending along the longitudinal edge. The channel has a planar central portion substantially parallel to a plane defined by an upper horizontal surface of the loading deck and opposing side portions extending vertically upward from the central portion.

Abstract: An improved cargo restraint attachment assembly for use with a platform trailer includes a body having an interior side and an exterior side opposite thereto. A first section is adjacent to the interior side and configured to attach the body to a loading deck of the platform trailer so that the body extends outwardly from and along at least a portion of a longitudinal edge of the loading deck. A second section is configured to selectively secure the cargo restraint device at a desired position with respect to the longitudinal edge. The assembly may secure at least one cargo restraint device at an angle with respect to a horizontal plane to minimize bending moment on the cargo restraint device from force applied thereto by engagement with a load on a loading deck of the platform trailer.
