An airborne delivery system employs unmanned aerial vehicles (UAVs) released from an airborne platform, such as a Joint Precision Airdrop System (JPAD), to more accurately deliver supplies. The airborne delivery system is configured to be mounted on a JPAD, or similar airborne platform. As with a conventional JPAD, the JPAD is then released from an airborne vehicle. After a certain amount of flight time, one or more UAVs are released mid-flight from the airborne delivery system.

Airborne multi-rotor delivery system

A system for wireless communication comprising a plurality of wireless stations; each station configured to receive and transmit communications on at least one channel, each station comprising at least one processor and at least one memory operatively connected to the at least one processor; the at least one processor being configured to sense communications on the at least one channel and to wait a predetermined number of units of delay before transmitting a communication on the channel; the predetermined number of units of delay before transmission of the next communication being operatively associated with communications by the respective units. A method for controlling access in a wireless communication system comprising providing a wireless network comprising a plurality of communication units configured to transmit and/or receive communications over a channel; each communication unit being operatively associated with a delay counter and a memory containing reservations for a communication unit to transmit.

Method and system for packet collision avoidance in a wireless communication system

An apparatus for the activation of a remote device having a transmitter to generate and transmit user-set special coded signals. The transmitter has a function selector switch to select modes of operation for the transmitter. Included is also a receiver to receive the user-set special coded signals, and the receiver also has a function selector switch to select modes of operation for the receiver. The function selector switch selects the following modes of operation for the transmitter: (a) a &ldquo;transmit/fire&rdquo; mode that enables a fire signal to be transmitted to the receiver; (b) a &ldquo;wake-up&rdquo; mode that enables a set-up receiver mode for immediate firing; (c) a program mode for low power transmission of programmed codes; and (d) a &ldquo;test&rdquo; and operational mode that enables an operational test of the apparatus with no firing output. The function selector switch on the receiver selects the following modes of operation for the receiver: (a) receive a &ldquo;wake-up&rdquo; of &ldquo;fire&rdquo; signal; (b) actuate either an electrical excitation output or an electromechanical solenoid output; (c) provide a continuity test for a blasting cap; (d) program the receiver for receiving programmed codes; and (e) conduct operational tests of the receiver.
