Abstract: A racing coach device stores a first path of travel along a racetrack over a first time period and a second path of travel along the racetrack over a second time period. The racing coach device identifies, for each of a plurality of geolocations along the racetrack, one of the first path of travel or the second path of travel that is associated with a shorter duration of time over which the user traversed a segment of thepath of travel associated with each of the plurality of geolocations. The device determines an optimal path of travel along the racetrack based on the identified first and second path of travel for each segment of the path of travel at each of the plurality of geolocations that results in a calculated lap time to traverse the racetrack that is less than the first time period and the second time period.

Abstract: A shot tracking and feedback system is disclosed that uses a camera to track a shot fired from a weapon and a moving target, such as a clay target. Radar may be used in conjunction with the camera to track the shot and the moving target. Tracking the moving target and the shot allows for determination of the paths of the shot and the target to determine and provide performance feedback, such as whether the shot was above or below the target and/or to the left or right of the target. The performance feedback and additional information may be provided on a display of the system or a user device having a display (e.g., watch, smartphone, etc.). A user may utilize the presented information to improve shooting accuracy.

The receiving module includes an electronic means positioned between the photodetector and the signal-processing module and capable of matching the impedance of the photodetector to maximise the signal-to-noise ratio of the electrical signal by minimising distortions of said electronic signal associated with incorrect impedance matching at the output of the photodetector, while maximising the level of the modulated electrical signal and the throughput of transmitted data.

Abstract: A targeting system operable to be used with a bow to assist an operator with striking a target with an arrow. The targeting system comprising a processor, a target sighting window, a ranging module and a projector. The processor is operable to determine a range (distance) to the target and determine an orientation of the bow to strike the target. The processor is configured to present a first sighting element on the target sighting window and project a second sighting element onto the target sighting window. The projected second sighting element appears to be closer to the target than the first sighting element, which may be aligned with the second sighting element to aim the bow. The projector is also operable to present a variable compensated sighting mark onto the target sighting window that is indicative of a compensated targeting axis.

Abstract: Techniques are provided for implementing a system for determining the range to a target object and orienting a map. In implementations, GPS data is used to determine the location of the system and an approximate distance from that location to the target. Based on the approximate distance, one or more parameters of operation of the system may be set. Modes of operation may be entered to further adjust parameters of operation. An optical pulse may then be projected at the target and its reflections collected and analyzed to calculate a distance measurement. A visual display may be adjusted based on the calculated distance estimate to the target.
