A portable data sensing and processing device for a SCUBA diver using a tank of compressed air wherein the device provides integrated information to the diver on a liquid crystal display screen to permit the diver to make a longer time variable depth underwater dive than would be permitted by the U.S. Navy dive tables for a no-decompression ascent.

Described are swivel systems and swivel assemblies for connecting a vacuum appliance to a vacuum accessory. The assemblies can include first and second arcuate members that each includes a tab and a receiving section so the latter can receive the other member's tab. The assembly can be adapted to be coupled to the accessory to permit the appliance to pivot relative to the accessory about two independent axes. The swivel system can include a vacuum adapter and a connector adapted to permit the vacuum adapter to pivot about a vacuum accessory. A plenum chamber can be formed in the adapter that is in fluid communication with one or more vacuum hoses to balance the airflow within the adapter. With the swivel systems and assemblies described herein, the versatility and efficiency of vacuum appliances and other tools can be improved through their multi-axes rotational capabilities and balanced airflow configurations.

A dive computer with a free dive mode and/or wireless data transmission capabilities. In one embodiment the invention relates to a diving apparatus including a dive computer having a free dive mode, where the dive computer is configured to calculate a nitrogen loading in the free dive mode using a default value which is the fraction of oxygen in air, and where the free dive mode is used when a diver makes a dive without a self-contained underwater breathing apparatus. Another embodiment includes a method of operating a dive computer including recording two or more first identifiers, receiving pressure information from two or more pressure transmitters, the pressure information comprising second identifiers and pressure measurements, determining whether the pressure information contains one of the two or more first identifiers, and displaying a message indicative of the pressure information that contains one of the two or more first identifiers.

The present disclosure provides a filter cage having an improved flow path suitable even for restricted flow regions of a float container in the cage. The filter cage departs from generally accepted structural considerations and provides flow paths to one or more sides of the cage outside the restricted flow regions of the float container, but within the cross-sectional area of the cage structure. In one exemplary embodiment, the cage is oval-shaped with a cross-sectional area defined by a major and minor axis. A restricted flow region, such as the float container, encompasses a cross-sectional area corresponding in size to a cross-sectional area defined by the minor axis of the oval-shaped cage. The remaining portion of the cage cross-sectional areas provides one or more flow paths outward from the float container in the direction of the major axis of the cage.
摘要:
A retaining system including a power cord retaining system and a cord plug retaining system for use with a power tool. The power cord retaining system is configured for accommodating an extension cord and includes a cord capture formation for retaining the extension cord disposed on the tool, and a cord channel disposed on the tool and configured for supporting a loop of the cord substantially along an arc defined by the loop. In the preferred embodiment, the cord capture formation defines an enclosed aperture for retaining the cord at two points, and the cord channel defines a semi-circular arc for supporting the cord loop substantially along its apex. The plug retaining system is configured for maintaining electrical continuity between the plug and the receptacle and includes a contact portion for engaging a plug or a cord, and an attachment device for attaching the contact portion to the tool.

A tank strap tightening actuator for securing a SCUBA air tank to a diver's backpack by means of a strap which engages the backpack and surrounds the tank with the two free ends of the strap being hooked to said actuator around said tank, said actuator being activated by compressed air to tighten the strap.
摘要:
A snap-together wet nozzle for use with a vacuum assembly is described, as well as a removable squeegee assembly for use in combination with a wet nozzle for a vacuum assembly. The snap-together wet nozzle includes an elongated, generally U-shaped nozzle housing having outwardly tapering walls, spaced apart closed ends, and a connecting tube passageway for association with a vacuum-producing means, such as a wet/dry vacuum, and further includes a squeegee assembly capable of being insertably mounted within the elongated, generally U-shaped nozzle housing. The squeegee assembly generally includes a squeegee element comprising a plurality of openings extending through the squeegee element; a first, elongated squeegee bar having spaced apart end grooves at each of its ends; and a second, elongated squeegee bar having spaced apart locking end tabs at each of its ends and a plurality of vanes spaced across the interior face of the bar, wherein when the squeegee assembly is assembled and ready for insertion into the nozzle, the squeegee element is located intermediate between the first and second squeegee bars, and wherein the first and second squeegee bars interlock by the engagement of the end tabs of the second squeegee bar with the end grooves of the first squeegee bar.
