  • Patent number: 10642317
    Abstract: In some examples, a computing device may include a first housing mechanically coupled to a second housing. The coupling may enable the first housing to be placed at an angle of between at least 0 to 180 degrees relative to the second housing. A clasp may be used to temporarily hold the first housing against the second housing when the first housing is placed at an angle of about 0 degrees relative to the second housing. A clasp sensor may determine that a user touched the clasp. In response, the computing device may initiate a boot process of an operating system. The boot process may capture biometric data using a biometric sensor in the clasp and compare the biometric data with previously stored biometric data associated with the user. The boot process may authenticate the user when the biometric data matches the previously stored biometric data.

The respiratory mask may also include an external shield to enhance sealing and provide a barrier of protection for the healthcare provider. The mask's design allows for a novel handgrip technique that allows a single healthcare provider to ventilate with enhanced sealing.

  • Patent number: 7823585
    Abstract: A snorkel clip made up of two substantially rigid elements, which are designed to wrap at least half way around a snorkel tube, overmolded with a substantially flexible element to create a simple, aesthetically pleasing device. The snorkel clip also includes a hinge region created as part of the substantially flexible element. This hinge region allows the snorkel clip to flex or bend so that one of the rigid elements may be disengaged and pulled away from the riser tube of the snorkel, so that a mask strap may be attached to and removed from the snorkel, while the other rigid element remains attached to the riser tube in a generally secure manner. The substantially flexible portion may also include several cut out sections to provide visual and tactile access to portions of the substantially rigid elements for utility and aesthetic design.

  • Patent number: 7812279
    Abstract: A welding flash protection apparatus for use with a welding machine with gas shielding is disclosed, the apparatus providing for delay of the welding flash thereby preventing the typically inherent fraction of a second delay between flash and lens darkening, hence protecting the eyes. The apparatus provides a complete helmet or apparatus components for fitment to an existing helmet. The apparatus provides a unique transmitter antenna mount for the shielding gas tank.

  • Patent number: 7798142
    Abstract: A tubular body is operatively coupled to an oral nasal mask and provided with lateral apertures adapted for fluid flow. A flexible valve is mounted onto one end of the tubular body and adapted to seal the lateral apertures under normal operation conditions and expose the lateral apertures for fluid flow during emergency operation conditions. The sealed lateral apertures keep exhaust gases from escaping the oral nasal mask and contaminating the interior of the diving equipment during normal operation conditions. The exposed lateral apertures allow air from an alternate source to reach the mouth and nose of a user covered by the oral nasal mask during emergency operation conditions. The exposed lateral apertures allow excess water to be removed from inside the diving equipment. The valve system may be implemented as an integrated regulator mount nut/valve system.

  • Patent number: 7793656
    Abstract: A swim and skin-dive snorkel for providing positive end-expiratory pressure for pressure-balanced exhalation. The snorkel may include inhalation and exhalation conduits. Air can be exhaled into a chamber and released when exhalation pressure within the chamber exceeds a threshold pressure. The threshold pressure that must be overcome to achieve exhalation may be balanced against the compressive forces of the ambient water pressure acting against the user's chest and lungs, which may greatly reduce the resting expiratory flow rate, the minute respiratory rate, and therefore the overall work of breathing. The exhalation pressure may be linearly matched to the ambient water pressure as a function of dive depth, thereby discouraging exhalation while diving. A purge valve may also be placed at the lower aspect of the snorkel.

  • Patent number: 7730884
    Abstract: A diving apparatus includes a support structure (18) that is engageable with a diver's head, the support structure (18) defining a lens opening (262) and an equalization opening (104). A lens (26) is mounted on the support structure (18) to close the lens opening (262) so that the support structure (18) and the lens (26) define a breathing space (30) from which the diver can be supplied with air. A sealing arrangement is positioned on the support structure (18) sealingly to engage the diver's face so that the breathing space (30) is substantially airtight. An equalization assembly (106) is mounted on the support structure (18) to close the equalization opening (104). The equalization assembly (106) includes an access means to permit the diver to gain access to his or her nose so that the diver can carry out an equalization procedure. A gas supply arrangement is in fluid communication with the breathing space (30).

  • Patent number: 7621268
    Abstract: A snorkel has an inhalation tube and a check valve near a mouthpiece which allows air to flow toward the mouthpiece, and a float valve which closes the inhalation tube. An exhalation tube has a second check valve also located near the mouthpiece which only allows air to flow into the exhalation tube. The snorkel has a purge valve positioned below the mouthpiece. A further check valve is positioned between the inhalation tube and the exhalation tube to allow air or water in the exhalation tube to pass to the inhalation tube placed as close to the first check valve as possible. The exhalation tube outlet orifice may be closed by a simple gravity actuated valve which will float open during a dive. Alternatively the exhalation tube outlet orifice may be closed by a float valve.
