Abstract: Imaging range finding device and method are disclosed. The range finding device can include an array of emitters and photodetectors in optical communication with an imaging lens. During the range finding method, the emitters in the array can emit light that is directed by the lens toward a target object. The photodetectors in the array can detect light received from the object through the lens and onto the photodetectors. The lens, the array, or both can be movable to adjust the light emitted by the device. Characteristics of the emitted light and/or the received light can be used to find the object's range.

Abstract: Fabrication of an imaging range finder is disclosed. The range finder can be formed of an imaging lens and an array of emitters and photodetectors in optical communication with the lens. The emitters in the array can be formed to emit light that is directed by the lens toward a target object. The photodetectors in the array can be formed to detect light received from the object through the lens and onto the photodetectors. The lens, the array, or both can be movable to adjust the light emitted by the range finder. The range finder can be formed to find the object's range based on characteristics of the emitted light and/or the detected light.

Abstract: Ultrasonic transmitters that can be used for ranging in mobile devices are disclosed. In some examples, an ultrasonic transmitter device can be configured to transmit ultrasonic signals in multiple frequency bands. The transmitter can include multiple sets of ultrasonic transmitters, each capable of transmitting in a different frequency band. In other examples, frequency-adjustable ultrasonic transmitters can be used. The transmitters can be configured to change one or more of a length, mass, or tension of a membrane to change a resonant frequency of the membrane. In some examples, the transmitter can include a non-uniformly shaped membrane capable of vibrating at more than one resonant frequency. The ultrasonic transmitters can be included within a housing configured to control the flow of air within and out of the housing. The transmitter membrane can further be formed on a patterned substrate configured to increase the sound pressure levels produced by the transmitter.
