Abstract: A paddlecraft with a recess in its deck for a hookah diving compressor is disclosed where a user can paddle to a dive site and dive there without removing the compressor from the recess. An interchangeable insert for the recess supports different shapes and sizes of compressors. For a water-cooled compressor, the recess admits water from beneath the paddlecraft, or part of the compressor protrudes through the recess into the water beneath. A lid for the recess with an attachable tube feeds air to the compressor. An airline connection point is integrated into the paddlecraft, readily allowing connection and removal of an airline, or two or more airlines via an adaptor. The paddlecraft can also house an air reserve tank, allowing the user to dive without removing it. If the paddlecraft is an SUP, part of the SUP deck preferably functions as an air reserve tank.

Abstract: A CO2 refrigeration system includes a CO2 refrigeration subsystem that provides cooling for a refrigeration load using carbon dioxide (CO2) as a refrigerant. The CO2 refrigeration system further includes a direct CO2 heat exchange subsystem that uses the CO2 refrigerant from the CO2 refrigeration subsystem to provide heating or cooling for a building zone. The direct CO2 heat exchange subsystem includes a heat exchanger that exchanges heat directly between the CO2 refrigerant and an airflow provided to the building zone.

Abstract: A two-section kayak is disclosed where a user can create a gap between a kayak front section and a kayak back section, and use this gap to enter and exit the water. Connecting poles are preferably used to create the gap and retain structural integrity of the kayak when the two sections are separated. A variety of foot stirrups and ladders are contemplated to allow a user to more easily reenter the kayak through the gap. One or more gap alcoves are contemplated to store a stirrup or ladder and to allow the user ready access to swimming, snorkeling and scuba diving accessories while in the gap. A viewing portal, and a hanging seat/platform are contemplated for attachment in the gap, to allow users a more varied kayaking experience. An optional third kayak section is contemplated to add storage space or turn a single kayak into a double kayak.

Abstract: A contact information function associated with a web browser maintains a look-up table of recognizer functions, indexed by regular expressions that specify URLs. Upon a user entering or selecting a URL, the contact information function indexes the look-up table with the URL against the regular expressions. If one or more recognizers are found, the web content returned from the URL is processed by each of the recognizers, which recognize the format of information on that web site, and locate and extract contact information from the web content. The contact information may be saved, formatted, and output to other applications. Updated recognizers may be downloaded from a recognizer server.

Abstract: To provide the illusion of smooth motion during zoom or pan operations of an interactive map display, relatively unimportant map elements are not rendered during map movements. By reducing the number of elements to be rendered in each frame during the movement, a map display rendering engine can increase its frame rate, thus providing the illusion of smooth motion. At the completion of the zoom or pan operation, the omitted elements “fade in” by successively rendering the same frame with the omitted elements' opacity gradually increasing in each frame. The selection of map elements to omit during map movement is made by comparing a dynamic value stored with each layer of map elements to a rendering performance value, which may be based on the computational power of the rendering engine, and may be set upon installation of the map software.
