Abstract: A patient interface includes a frame assembly including connectors operatively attachable to headgear, a cushion assembly provided to the frame assembly and including a seal-forming structure structured to form a seal with the patient's nose and/or mouth, and an air delivery connector provided to the frame assembly and operatively connected to an air delivery tube for supplying the air at positive pressure along an air flow path. The cushion assembly is structured to releasably connect to the frame assembly independently of the air delivery connector. The air delivery connector is structured to releasably connect to the frame assembly independently of the cushion assembly.

Abstract: A blockage clearing device is disclosing having a reservoir tube with a hollow interior configured to hold an amount of fluid. A piston plunger is disposed within the hollow interior of the reservoir tube and an injector nozzle is coupled to an end of the reservoir tube, the injector nozzle having an injector opening configured to receive and release fluid. A gasket seal surrounds the injector nozzle wherein the injector opening is accessible from an exterior of the gasket seal. The gasket seal is configured to fit between a siphon waste and siphon jet of a toilet wherein the siphon waste is sealed from the siphon jet.

Abstract: A system displays information on one or more products or services to a shopper using an easily-controlled system for selecting the displayed information. The system uses a display device capable of retrieving information from local or remote memory for display in response to these commands from a shopper. The user controls the display device by physical motion of the display in communication with one or more nearby display cards containing one or more triggering symbols representing a product or service of interest. The display device senses the selected trigger and displays information related to the selected product or service. The shopper may also select differing types of information using the user camera and touch capability of the display device.

Abstract: An electronic device and/or a method of sealing said device are configured for ease of installation and use. The electronic device has a housing having a recess, a cover concealing the recess and having walls extending circumferentially around the cover and having a channel formed in the outer surface thereof, and at least two through-holes formed through the channel, and an O-ring having a body with at least two tethers each of which passes through a respective hole in the cover.

Abstract: A magnetically coded card and a lock include a slot into which the card is inserted to operate the lock. The card has an aperture through which a card-impaling lock-in pin of the lock can pass when the card is fully inserted within the slot, thus retaining the card in the slot when the lock is unlocked and releasing the card when the lock is again locked.

Abstract: A magnetic card-operated lock has a rotatable exposed cover with a peripheral slot into which a magnetic coded operating card can by inserted for unlocking or locking the lock. The cover and principal locking components are mounted to rotate freely about a central axis between a null position and an unlocking position. A positionable weight is mounted to rotate with the cover plate and is radially separated from the axis so as to bias the cover towards various null positions under the action of gravity. There is also a card lock-in mechanism comprising a card lock-in pin that retains a card in the slot while the lock is unlocked, and a card for said lock with hole and dimple projections to retain it when inserted into the slot.
