Abstract: A system configured to protect valuable, sensitive, or electro-mechanical equipment during cleaning of the equipment can include a cover having a single opening leading to an interior cavity. The cover can be waterproof. A plate can be permanently attached to the cable of the equipment. An outer periphery of the plate can be approximately the same size as an inner periphery of the opening. The plate can be configured to sealingly fit within the single opening. The system can include a latching mechanism configured to sealingly attach the plate to the cover.

Abstract: There is presented a removable high-intensity focused ultrasound (HIFU) transducer and supporting system that allows for HIFU transducer assemblies and other therapeutic ultrasound assemblies to be attached to third party positioning, imaging, or guidance systems while maintaining the required focal-zone positioning ability and the required acoustic energy coupling to tissue, to mechanically or automatically ablate a target volume in unimpeded fashion. There is provided an acoustically transparent and pliable vessel that has an open top end and filled with acoustic coupling fluid, capable of holding the transducer assembly and distal end of the positioning system within it as it executes the HIFU treatment plan/process. The vessel is held in place using a transducer/positioning system and independent external fixturing mechanism.

Abstract: A vertical door locking system includes a door lock with a deadbolt that moves horizontally, a striker with an upward facing strike opening that vertically receives the deadbolt and a lock controller. The striker includes an electrically operated catch to engage and release the deadbolt. The door lock and striker are mounted opposite each other, one to the vertical door and the other to an adjacent fixed mounting point. The lock controller electrically operates the striker to release the deadbolt and allow it to move vertically out of engagement with the striker for primary access to a secure area and the door lock allows the deadbolt to be retracted horizontally away from the striker for secondary access. A remotely located control system optionally controls the lock controllers of multiple doors and a central office control system is optionally connected to multiple remotely located control systems.
