Abstract: The present disclosure provides systems and methods for detecting the presence of blood. Specific applications may include hunting, during which it may be necessary to track a wounded, bleeding animal. According to one embodiment, a device transmits light at one or more wavelengths to irradiate a region potentially containing blood. Hemoglobin in the blood absorbs or reflects more of the transmitted light than other matter in the region. A detector detects the light reflected from the region and determines if blood is present in the region using spectral analysis.

Abstract: The solar array is attached to a support structure which permits it to pivot about two non-parallel and non-intersecting axes. The array may then be easily moved to track the sun, maintaining the production of electricity. The structure may be adapted for attachment to a surface such as the ground.

Abstract: A multi-sensory parking guidance system using visual, auditory and tactile feel indicators to guide a driver into an optimal position to park a vehicle. The invention also indicates the appropriate stopping position within a parking space.

Abstract: A device for use in conjunction with a coordinate measuring device, a three-dimensional coordinate measuring system and a method of measuring three-dimensional coordinates are described. The device includes a light source mounted substantially within the center of a spherical member having a spherical surface configured such that the distance from the light source to the outer contact surface of the sphere is substantially equal to the radius of the sphere regardless of sphere orientation. The three-dimensional coordinate measuring system further includes a coordinate-measuring device, the coordinate-measuring device configured to track the movement of the light source and to measure either azithmuth angles and zenith angles, or to spherically encode tracking information related to relevant positions of the light source.

Abstract: A scale-bar artifact is and measurement method is provided, the artifact comprising a shaft, at least one mounting nest positioned on the shaft, a plurality of target nests positioned on the shaft, at least one temperature sensor in contact with the material of the shaft and a computer or circuit board in communication with the at least one temperature sensor, wherein the computer or circuit board is configured to receive temperature sensor data and to compile temperature corrected distance measurements corresponding to at least one linear portion of the shaft. Additionally, a scale-bar artifact is provided, comprising a shaft, a plurality of target nests positioned on the shaft and at least one mounting nest positioned on the shaft, wherein the at least one mounting nest comprises either at least one adjustable kinematic mounting nest or at least one fixed kinematic mounting nest configured to receive a separate mounting component.

Abstract: An absolute distance measurement device is provided, including reference and measurement laser signal paths, comprising a laser source providing a laser signal and a chopper assembly, comprising a rotatable surface defining at least one aperture provided through a portion of the rotatable surface; wherein the laser signal is directed to different points on the rotatable surface of the chopper assembly such that as the rotatable surface is rotated, the aperture selectively permits transmission and selectively prevents transmission of each of said at least two laser signal paths.
