Abstract: The vehicle crew communication system provides up to sixty wireless headsets that can be used with one base station, a range of 1600 feet from the base station for operation of the headsets, full duplex operation communication over digitally encrypted DECT protocol links from one base station to a plurality of headsets, pairing of each headset to a particular base station, use of wireless technology inside and outside of the vehicle, automatic channel and link selection to transparently avoid interfered-with channels and links, removal of the need to manually select a channel on the headset, and the combination of the noise-cancelling microphone with noise threshold, noise attenuation, and line echo cancellation tuned to intercom parameters. The invention may be used with or without a vehicle.

Abstract: A wireless intercom has a releasably coupled wired interface to an external aircraft communications socket and the wireless intercom is coupled to the aircraft proximate the socket, preferably in a custom bag hung by a releasable mechanical coupling to the aircraft. The wireless intercom provides signal communication and management between a ground crew tug driver headset and the pilot via the socket and, in various embodiments, to a trainer headset and/or to one or more wing walker headsets. If the wireless intercom loses communications with the tug operator headset during ground operations, an alarm is sent to the pilot via the socket. The wireless intercom, in alternate embodiments, enforces a priority scheme for calls going to one or more of the headsets. The wireless intercom and headsets are powered by rechargeable batteries. Each embodiment includes a customized weather-resistant case for holding at least the other elements of that embodiment.

Abstract: The improved vehicle crew communication system provides an increase in the number of wireless headsets that can be used with one base station, an increase range from the vehicle for operation of said headsets, full duplex operation communication over digitally encrypted DECT protocol links from one base station to a plurality of headsets, pairing of each headset to a particular base station, use of wireless technology inside and outside of the vehicle, automatic channel and link selection to transparently avoid interfered-with channels and links, removal of the need to manually select a channel on the headset, and the combination of the noise-cancelling microphone with noise threshold, noise attenuation, and line echo cancellation tuned to intercom parameters.

Abstract: A hook having a fastener receiver with an axis of radial symmetry and two opposing edges defining a linear axis, where a support extends from the first edge and is angled away by a first angle from a midline plane defined by the linear axis and the axis of radial symmetry and a retainer extends from the second edge and is angled away from the midline plane by a second angle, preferably equal to the first angle and oppositely directed. The hanger hook is preferably of one piece construction but a two-piece interlocking version may also be made. Direct access to the fastener receiver is provided for tools and fasteners. The hanger hook retains equipment against 9 G horizontal accelerations and 3 G vertical accelerations.
