    Abstract: 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.

    Abstract: 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.

    Abstract: A video taking device comprises a video camera, an auxiliary controller and a main controller, wherein the video camera is electrically connected with the auxiliary controller and the main controller and the auxiliary controller is electrically connected with the main controller. The video camera is configured to film to generate a video stream. The auxiliary controller is configured to determine whether there is a target existing in the video stream, and to generate a switch instruction when the target exists in the video stream. The main controller is configured to switch into a first operation mode from a first standby mode and instruct the auxiliary controller to be in a second standby mode when receiving the switch instruction, and to obtain the video stream from the video camera for recognizing appearance of the target.

    Abstract: A direction controllable lighting unit 10 for use in a lighting system is described. 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.

    Abstract: A method and apparatus for accurately and precisely detecting a position of a mobile robot are disclosed in which infrared signals having different specific frequency values according to rotational angles, an angle is determined by receiving the generated infrared signals, and a distance is calculated on the basis of a time taken for receiving a ultrasonic signal after being oscillated. The method for detecting a position of a mobile robot includes: a step in which a mobile robot receives an infrared signal generated from an infrared generator according to a rotation angle of the rotated infrared generator; a step in which an angle between the mobile robot and the infrared generator is determined on the basis of the specific frequency value of the received infrared signal and previously stored frequency values; a step in which a ultrasonic signal oscillated from a ultrasonic signal oscillator is received when the infrared generator reaches a predetermined angle; a step in which a distance between the mobile robot and the ultrasonic wave oscillator is calculated by multiplying a sound velocity to a time taken for receiving the ultrasonic signal by the mobile robot after being oscillated; and a step in which a position of the mobile robot is detected on the basis of the determined angle and the calculated distance.
