Abstract: Systems and methods for a facemask wearer to view high resolution, high data content, color imagery are provided. A display using organic light emitting diode (OLED) micro-displays provides 800×600 color pixel resolution at 60 Hz. The OLED micro-displays allow for powering the system through a standard Universal Serial Bus (USB) port connected to a compatible sensor system that provides the required power and standard display signal to the OLED display. The display is held away from the user's field of view by a quick release facemask attachment bracket. The bracket can provide for flipping the display up and down, swiveling the display, or rotating the display with one hand. When needed, the display can be flipped down, such that the display is in contact with the facemask faceplate, enabling clear, focused images even in zero visibility water.

Abstract: An assembly for securing an apparatus to a facemask includes a U-shaped frame extending along similarly shaped portions of the facemask. Removable attachment clips secure the frame to the facemask. Two cylindrical pins with circumferential radiused grooves are attached to and extend from the top portion of the frame. The pins mate with bores in a clevis assembly, to which the apparatus can be attached. A spring-loaded bar spans between the bores. The bores in the clevis assembly receive the pins and the spring-bias causes the bar to engage with the grooves to secure the clevis assembly to the frame. A lever is rotatably attached to the clevis assembly. Pivoting the lever works against the spring-bias to lift the bar out of the grooves, disengaging the pins, and allowing the clevis assembly to be disengaged from the frame and facemask.

Abstract: An index bracket assembly positions an external apparatus on a facemask having top and side portions extending to lower corners. A U-shaped frame connected to the external apparatus has top and side openings and a U-shaped bearing surface having orthogonally extending feet at its opposite ends. The U-shaped bearing surface extends along the top and side portions and the feet abut against the lower corners of the facemask. A three-point harness has a top strap connected to the top opening and side straps are connected to the side openings. The top strap and side straps each have a separate adjustable buckle component connected together for tightening them and pulling the U-shaped bearing surface against the top and side portions of the facemask. A layer of compliant material on the U-shaped surface elastically yields to the top and side portions of the facemask to prevent slippage.

Abstract: A system is provided for monitoring one or more depth associated parameters of an object submerged in water. A first set of alarm devices are mounted in the system's housing such that they are accessible from the exterior thereof. The first set of alarm devices, defined by an audio generator, a tactile generator, and a light, are initiated in accordance with a predetermined initiation scheme when at least one of the monitored parameters does not satisfy predetermined threshold criteria associated therewith. A second set of alarm devices are tethered to the system's housing for remote positioning with respect thereto. The second set of alarm devices utilize the same types of alarm devices as the first set of alarm devices and are also initiated in accordance with the predetermined initiation scheme.

Abstract: A system and method indicate azimuth of a diver to a remote console. A compass sensor module on a headgear worn by the diver has a two-axis gimbal mechanism provided with a protective housing around ring and two orthogonal axis structures. A magnetic field sensor unit mounted on one axis structure provides magnetic field data signals representative of the azimuth faced by the diver. A processor section of the compass module connected to the sensor unit provides azimuth data signals from the magnetic field data signals. A data transmission module has a conductor extending from the compass module to an amplifier and cable for amplifying azimuth data signals and remotely transmitting them. An acoustic transducer in the data module can also transmit azimuth data signals as acoustic signals through water. The console connected to the cable and water receives and displays the remotely transmitted azimuth data signals.

Abstract: A system and method indicate the direction faced by an operator. A waterproof housing has a mounting mechanism to engage a part of a headgear worn by an operator to position the housing in a portion of the operator's forward field of view. A two-axis gimbal mechanism is inside the waterproof housing and has a protective housing connected to the waterproof housing. The protective housing contains ring structure coupled to two orthogonal axis structures. A magnetic field sensor module is mounted on one of the axis structures and provides magnetic field data signals representative of the direction faced by the operator. An optical element has a wide field of view to transmit compass data images representative of the magnetic field data signals to the eyes of the operator.
