Abstract: A detecting equipment and a movable platform are provided. The detecting equipment includes a light-emitting component, a photosensitive component, a processing component, a first optical element, a second optical element, and a circuit board. The circuit board contains a first through-hole and a second through-hole. A light signal emitted by the light-emitting component is configured to successively pass through the first through-hole and the first optical element, and a light signal reflected by a target object is configured to successively pass through the second optical element and the second through-hole to reach the photosensitive component. According to the light signal emitted by the light-emitting component and the light signal received by the photosensitive component and reflected by the target object, the processing component is configured to determine information associated with the target object.

Abstract: A method of ultrasound distance detection includes identifying an ultrasound echo from an object and determining a distance between a mobile platform and the object based upon the ultrasound echo. Identifying the ultrasound echo includes dividing a sonic waveform received by the mobile platform into packets, filtering the packets using at least a threshold packet bandwidth to identify one or more candidate packets that are not noise, and identifying the ultrasound echo from the one or more candidate packets. The threshold packet bandwidth is multiple of an average width of previously known echoes.

Abstract: A system for detecting objects using ultrasonic waves and methods for making and using the same are provided. The object detection system uniquely encodes each of a plurality of ultrasonic waves and transmit each of the uniquely-encoded ultrasonic waves in a respective direction. The object detection system then receives any of the emitted uniquely-encoded ultrasonic waves that are reflected from an object. By decoding the reflected ultrasonic waves, the object detection system distinguishes among the uniquely-encoded ultrasonic waves and detect the existence and location of the object.

Abstract: An apparatus includes a light source configured to emit light, a beam shaper configured to project the light to substantially surround the apparatus in a plane and onto an object in the plane, and a receiver configured to project the light reflected from the object in the plane to an image sensor. A distortion parameter of the receiver in conjunction with a difference between the emitted light and the reflected light detected at the image sensor is indicative of at least one of a direction or a distance of the apparatus relative to the object.
