Abstract: A head up display system includes first and second optical waveguides. A bracket holds the optical waveguides in a spaced-apart fixed relationship to one another such that their optical axes are separated by a distance of 63.5-65 millimeters. The optical waveguides are angularly disposed with respect to one another to produce a binocular image whose focal plane is located out at a distance of 2-4 meters. The bracket also specifically positions the optical waveguides adjacent to a transparent face plate of a dive helmet or dive mask.

Abstract: A breathing-air tank pressure tracking system includes a housing having lights mounted therein. The lights are spaced-apart from one another and disposed along a line. A pressure sensor is coupled to a tank containing pressurized breathing air. The pressure sensor detects a pressure of the pressurized breathing air and produces a signal indicative thereof. The housing is configured to be coupled to an exterior portion of a dive helmet wherein the lights are positioned in a field-of-view of a user wearing the dive helmet. A controller, mounted in the housing, is coupled to the pressure sensor and the lights. The controller activates selected ones of the lights based on the signal received from the pressure sensor.

Abstract: A wetsuit drying and transportation carrier includes a container having a wetsuit receiving interior. A reservoir is provided adjacent to the bottom of the container to receive liquid from the interior of the container. A first wetsuit support is pivotably connected to the container to pivot into and out of the container interior. A second wetsuit support is pivotably connected to the container in front of the first wetsuit support to pivot into and out of the interior of the container. A wetsuit shoulder support is connected to the container or to the first wetsuit support. A third wetsuit support is pivotably connected to the first and second wetsuit supports. The third wetsuit support desirably has a slot for receiving a wetsuit for drying and transportation.

Abstract: A plurality of users may access a processing unit operable for the development of a model, and model development instructions from the users may be received at the processing unit. The model may be developed in a plurality of steps using the model development instructions. Signoff instructions corresponding to the steps for developing the model may be received at the processing unit, each of the signoff instructions being received after each corresponding step is performed, with each of the plurality of signoff instructions indicating approval or denial. The respective step may be approved by the processing unit if the corresponding signoff instruction indicates approval, and rejected by the processing unit if the corresponding signoff instruction indicates denial. The processing unit is operable as a central location accessible by the users for developing, and signing off on the development of, the model according to the development instructions and the signoff instructions.

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 method and system displays information in a full face mask. A display module is mounted inside the full face mask on faceplate support structure outside of a forward viewing area of a faceplate portion. The display module is located to be free of interference with an operator's forward field of view through the forward viewing area. A display control module is externally mounted on outside components of the full face mask and has a waterproof housing, processing and display driving electronics, memory, internal sensors, external sensors, and battery. A power-data cable is connected to the display control module externally mounted on the full face mask and to the display module inside the full face mask via an accessory interface plate. A switch on the display control module can be accessed and selectably actuated by an operator to present data from the display control module on the display module.

Abstract: A full face mask has a body frame having a continuous, closed sidewall extending and compliantly resting on bony contours around facial features of a wearer, and a lateral partition extending and resting on bony contours of a wearer's face from one side to another side of the sidewall between the areas of the nose and upper lip. The lateral partition separates the frame into a lower mask section having a lower cavity with a pod opening and an upper mask section having an upper cavity. Lenses supported by the frame define a forward field of view and integrated in the frame are components including a radio frequency antenna receiving dive information signals, a display in a peripheral area outside of the forward field of view, a controller coupled for processing the signals to generate outputs, and a control that passes outputs for display at the visual display.

Abstract: An underwater swim board enables diver navigation under conditions of zero visibility. A rectangular member has a timer, depth gauge, and compass on its topside to provide a visual indication of time, depth and direction. An enhanced display module on the bottom side of the member contains a microprocessor to receive time, depth, and direction signals from separate electronic timer, depth transducer, and magnetic compass modules in the display module creates representative control signals. The display module also has a display screen and an LCD having variable backlight to vary its light intensity. The LCD receives the control signals and displays the information of the time, depth, and direction signals on the screen. A virtual image display lens mounted on the screen allows binocular viewing of the displayed information as magnified near-to-the-eye apparent screen images for a diver holding a dive mask faceplate against the screen.

Abstract: A microchannel phosphor screen for converting radiation, such as X-rays, into visible light. The screen includes a planar surface, which can be formed from glass, silicon or metal, which has etched therein a multiplicity of closely spaced microchannels having diameters of the order of 40 microns or less. Deposited within each of the microchannels is a multiplicity of phosphors which emit light when acted upon by radiation. The dimensions of the microchannel and the phosphors and the relationship between the microchannels and the phosphors is optimized so that the light output compares favorably with lower resolution non microchannel based scintillation screens. A photomultiplier can be integrated with the X-ray detector so as to provide an enhanced output for use with low level X-ray of for cine or fluoroscopy applications.

Abstract: A dive mask display system integrates a plurality of components in the mask's frame. These components can include: a radio frequency (RF) antenna for receiving RF signals indicative of dive information, a display that is directly viewable in a peripheral vision area of the diver but outside of the field of view defined by the mask's lens(es), a diver-controlled controller, and a depth sensor. The various monitored information, as well as bottom time tracked by the controller, can be displayed simultaneously.
