A terrestrial acoustic sensor array for detecting and preventing airspace collision with an unmanned aerial vehicle (UAV) includes a plurality of ground-based acoustic sensor installations, each of the acoustic sensor installations including a sub-array of microphones. The terrestrial acoustic sensor array may further include a processor for detecting an aircraft based on sensor data collected from the microphones of at least one of the plurality of acoustic sensor installations and a network link for transmitting a signal based on the detection of the aircraft to a control system of the UAV.

A multi-spectral detection device is provided that includes a housing, a bezel spacer, a microphone, an end cap and electro-optical sensors mounted to the end cap. The housing has an inner chamber that holds sensor components. The bezel spacer has a first end and an opposed, second end. The first end of the bezel spacer extends from a first end of the housing. The bezel spacer has a central bezel passage leading to the inner chamber of the housing. The bezel spacer further has at least four side walls. Each side wall is positioned 90 degrees away from an adjacent side wall. A microphone is coupled to each side wall of the bezel spacer in such a manner that each microphone is faced 90 degrees with respect to an adjacent microphone to form a compact acoustic array. The end cap is coupled to the second end of the bezel spacer and the electro-optical sensors are mounted to the end cap.

A remote transaction system is disclosed which may be used to conduct business transactions wherein visual contact between a buyer and a seller is desired or required. A transaction booth is located remotely from an operations center, the booth and the center being connected by audio and video communication lines. The booth includes audio and video equipment for transmitting and receiving audio and video signals between the booth and the center. Decoders are provided in the booth to receive telephone touch tones or pulses from the operations center and to control the audio and video equipment and other equipment in the booth. Alternatively, a programmable device, such as a controller or microcomputer, generates control signals for controlling the equipment. A dispenser unit is controllable from the operations center utilizing a decoder to selectively dispense items or objects to a customer. A payment module facilitates payment for items or services by cash, credit card, or other appropriate meams. The various equipment included in the booth is assembled into modules which can be simply and easily installed in the booth and interconnected using a wiring harness, facilitating the assembly and maintenance of the system.
