Abstract: A tactical flyers ensemble includes a breathable full pressure half suit (“FPHS”) bladder worn as an undergarment beneath a coverall. The coverall has a lower section specially adapted to most effectively constrain the FPHS when the latter is pressurized under flight conditions. Although thus adapted, the coverall remains fully utilitarian and can be worn with or without the FPHS under conditions other than those immediately preparatory to or during actual flight.

Abstract: An ear seal is disclosed for use in a headset. The ear seal includes a flexible sheath that encloses and is in contact with flowable material. The flexible sheath includes a first surface that extends between inner and outer peripheral edges of an annular top. The first surface is adapted for contacting a user's head and includes an inner annular groove separating an inner annular surface portion from a crease inhibiting central annular surface portion, and an outer annular groove separating an outer annular surface portion from the crease inhibiting central annular surface portion.

Abstract: An integrated pilot protection and restraining system having a circular bearing structure configured to surround the neck of the wearer, and a non-conformal helmet which is detachably coupled to and rotatably supported by the bearing structure. An automatic helmet rotation system is provided for controlling rotation of the helmet in response to movements of the wearer's head in order to maintain the helmet in a predetermined position with respect to the wearer's head. The system further includes a restraining anchor disposed on a rear portion of the bearing structure at its non-rotating base proximate to the base of the wearer's neck. The restraining anchor is coupled to a retractable restraining device.

Abstract: A headset has an arcuate resilient headband with arcuate stirrups at its opposite ends carrying noise attenuating ear domes. The stirrups are coupled to the headband for pivotal movement about first parallel axes. The ear domes are coupled to the stirrups for both pivotal movement about second axes extending transversely with respect to the first axes, and translational movement toward and away from each other between multiple pivot positions located along third axes extending transversely with respect to the second axes.

Abstract: A pressure garment has one or more bladders defined by flexible micro-porous material consisting of at least two layers, one layer being hydrophilic and facing inwardly towards the wearer's body, and the other layer being hydrophobic and facing outwardly away from the wearer's body.

Abstract: A microphone boom assembly for a communication headset has an elongated relatively rigid base section mounted on an ear dome or the like in a manner permitting both rotation about a first axis and longitudinal or translational movement along a second axis transverse to the first axis. A rigid intermediate section is joined to the base section at a hinge joint permitting rotation of the intermediate section about a third axis transverse to the second axis. A bendable and torsionally adjustable outer section leads from the intermediate section to a socket containing a microphone.

Abstract: A pressure garment has a transparent exterior panel with a pair of lower sections adapted to be operatively positioned around the legs of the wearer, and with an upper section adapted to be positioned around the abdomen of the wearer. Transparent inner panels cooperate with each of the exterior panel sections to define pressure chambers therebetween. A pressurized gas such as for example compressed air, is introduced into the pressure chambers in order to inflate the same and apply pressure to the wearer's body.

Abstract: A sound powered headset has a curved headband with stirrups mounted at its opposite ends for pivotal movement about first axes. Earphone assemblies are supported by the stirrups for pivotal movement about second axes extending transversely to the first axes. The headband is configured to operatively position the earphone assemblies over the user's ears. A microphone assembly is supported by tubular arm members which are connected to each of the earphone assemblies for rotation about a third axis extending transversely to the aforesaid first and second axes. The microphone assembly contains a known device for converting sound waves to electrical impulses and the earphone assemblies likewise contain known devices for converting electrical impulses to sound waves. The arm members are sufficiently rigid to maintain the microphone assembly spaced in front of the user's mouth when the earphone assemblies are operatively positioned.

Abstract: An apparatus for the treatment of a victim suffering from shock includes a single piece, double-walled panel of flexible material forming a chamber adapted to receive and contain a pressurized gas. The panel has a pair of lower sections adapted to surround the legs of the victim, and an upper section adapted to surround the abdomen of the victim in the region below the victim's rib cage. When the panel is inflated by the introduction of pressurized gas into the chamber, a pressure is exerted on the legs and abdomen of the victim, thereby decreasing the volume of venous blood pooled therein and producing an increased venous return to the victim's heart. This external pressure also provides immobilization for the victim and affords to him protection and comfort while being transported from an accident site to a medical facility.
