Abstract: Systems and techniques for facilitating archery implemented in conjunction with a bow mountable laser-based speed measurement instrument or a speed sensor bar as well as a bow movement sensor system which may be affixed to any of the available mounting positions on a conventional bow.

Abstract: A zoom optics structure for implementation in a laser-based rangefinding instrument provides a magnified image of a target. The structure disclosed can also serve to magnify a reticle or other information on an in-sight display in conjunction with the magnified target image. The zoom optics structure disclosed is also amenable to rangefinding instruments incorporating ballistics interfaces and those having image stabilization.

Abstract: A laser-based rangefinding instrument for, inter alia, golfing or hunting activities having an unique ergonomic design and an external multi-function switch for controlling display brightness, selectable display of differing distance units and a slope selection switch for enabling display of line of sight distance or angle of slope and “Compensated Golf Distance” slope distance to a target.

Abstract: A precise bearing measurement device wirelessly couplable to an associated rangefinder for providing the rangefinder with the horizontal bearing of the device. The device comprises a rotor board and parallel and spaced apart resolver board to which it is capacitively coupled. A processor and an inclinometer are provided to ensure the device is maintained in a level orientation when taking a bearing measurement.

Abstract: A system and method for determination of origin displacement for a laser rangefinding instrument which comprises laser transmitting and receiving sections coupled to a processor section. The processor section is configured to calculate ranges from the instrument to first and second target coordinates and to compensate for displacement between disparate first and second origin points in order to determine a distance between these target coordinates.

Abstract: An optical baffle and combination with a laser sensor of especial applicability in attenuating off-axis laser light in the use of a laser sensor for determining the height of a liquid level or distance to a surface detectable through a pipe.

Abstract: Disclosed herein is a handheld speed gun incorporating automatic number plate recognition (ANPR) functionality. As the image size of a vehicle license plate varies depending on its distance from the speed gun, in the present invention the distance to the target vehicle is known through the functionality of the laser sensor so the size of the pixels for the number plate can be estimated. Since the image of the number plate may be tilted in a handheld device, the present invention compensates for this by use of the instrument's tilt sensor or through other compensation by use of the image itself.

Abstract: A handheld laser-based vehicle speed measurement device incorporating on-board data storage with GPS, compass, excess panning detection, and voice recognition technology, as well as, recording minimum and maximum speeds of a plurality of vehicles along a roadway and calculating the 85th percentile speed.

The processor section is configured to calculate ranges from the instrument to first and second target coordinates and to compensate for displacement between disparate first and second origin points in order to determine a distance between these target coordinates.

Abstract: A system and method for a rangefinding instrument incorporating pulse and continuous wave signal generating and processing techniques for increased distance measurement accuracy. The use of the former technique effectively solves the ambiguity issues inherent in the latter while allowing for relatively simple circuit implementations. Thus, a potentially more accurate phase-based distance measurement technique can be utilized which is also completely independent of the maximum range to the target.

Abstract: A laser-based speed gun includes a camera module and a folded optical system including an objective lens and an eyepiece lens. The folded optical system includes first and second image redirecting elements for redirecting an image pathway from the objective lens to the eyepiece lens adjacent the camera module.
