摘要： An imaging system includes an illumination unit and a sensor unit disposed on a printed circuit board. The illumination unit includes a diode laser source inside an illumination housing. The sensor unit includes an image sensor having a pixel array and a lens barrel mounted on the image sensor with an adhesive, and an optical fiber coupled between the illumination housing and image sensor. The optical fiber is configured to collect a portion of light from the interior of the illumination housing that is emitted by the diode laser source and direct the portion of light to a corner of the pixel array of the image sensor that is located outside the lens barrel.

摘要： Aerial vehicles may be outfitted with one or more ultrasonic anemometers, each having ultrasonic transducers embedded into external surfaces. The transducers may be aligned and configured to transmit acoustic signals to one another, and receive acoustic signals from one another, along one or more paths or axes. Elapsed times of signals transmitted and received by pairs of transducers may be used to determine air speeds along the paths or axes. Where two or more pairs of transducers are provided, a net vector may be derived based on air speeds determined along the paths or axes between the pairs of the transducers, and used to generate control signals for maintaining the aerial vehicle on a desired course, at a desired speed or altitude, or in a desired orientation. The transducers may be dedicated for use in an anemometer, or may serve multiple purposes, and may be reoriented or reconfigured as necessary.

摘要： Disclosed are methods and systems for determining distance between two or more mobile devices utilizing a sound emitted from each device such as a chirp. Each device may determine or receive an indication of a time reference for each instance the device emits or detects a chirp. Utilizing the time reference data, the distance between the two or more devices may be determined assuming the sound travels at a constant speed of 340.29 m/s. Techniques for disambiguating orientation of the devices relative to one another rare also disclosed.

The light emission of the lighting unit 10 may be directed into different directions, e.g. by use of a mechanically movable element 14, 60. At least two ultrasound transmitters 20a, 20b, or ultrasound receivers 21a, 21b are disposed at the lighting unit 10 such that they differ in position, or in direction or shape of the spatial intensity distribution or spatial distribution of reception sensitivity. A mobile control element 46 has at least one corresponding ultrasound transmitter or receiver 50. A difference bebveen a signal from a transmitter received at multiple receivers, or a signal of multiple transmitters received at a single receiver is used to determine a relative direction of the direction controllable lighting unit 10 and the control element 46, and to control the direction of the lighting unit 10 in dependence thereof.
