An illumination apparatus comprises a housing configured to be coupled to an aerial vehicle. Coupled to the housing are a light source and a lens system at least partially covering the light source and configured to adjust an angular divergence of light therefrom. At least one position sensor is positioned within the housing and generates signals corresponding to an altitude of the illumination apparatus, a distance between the illumination apparatus and a ground surface, and/or a multi-axis angular position of the illumination apparatus relative to the ground surface. A controller within the housing adjusts the angular divergence of the light from the light source using the lens system based at least in part on monitored data from the at least one position sensor and a selected spot size of the light on a target wherein an actual spot size on the target is approximately equal to the selected spot size.

Illumination apparatus and method of controlled beam divergence for aerial vehicles

A device attachable to an aerial vehicle that incorporates electronics to control sensor position data and verify safety of aerial vehicle landing area. The device may be easily attached to an existing aerial vehicle. The device monitors sensor data from one or more distance measuring sensors and pressure sensors to set an angle of incidence for the distance measuring sensors. This pressure sensor derived angle setting allows for a continual data mapping of the aerial vehicles landing area to enhance and improve the landing zone.

Apparatuses, systems, and methods for improved landing of aerial vehicles

An apparatus is provided which may be selectively used in a variety of different ways. In one example the apparatus may be attached to one or more preexisting optical accessories to allow a user to view external environmental information concurrently when looking through the ocular lens of an optical device. Advantageously, such an implementation may permit a user to effectively obtain environmental data without moving away from an optical device. In another example, an optical system may be used to selectively attach an external device to an optical device to transmit environmental data recorded by the external device in order to superimpose an image through an ocular lens to be displayed concurrently with a target scene.

Optical accessory projection system

A time-of-flight laser distance device includes a laser transmitter, a laser pulse return detector to receive reflected laser pulses, and comparators with respective first and second trip levels. A preliminary distance to a target is based on a linear ramp as a function of lapsed time from laser pulse generation through an effective time period wherein an associated return pulse is detected. Time-of-flight values associated with a leading edge of the return pulse are obtained at each of the first and second trip levels. A time difference is determined between the obtained values, and a correction factor is applied with respect to the preliminary measured distance based on the determined time difference. A dual ADC may be used wherein the leading edge of the return pulse is calculated by measuring a slope associated with the time-of-flight values and extrapolating a slope origin to a zero crossing point.
