Abstract: An atmospheric ionizer includes a source that supplies electrical energy to an ion-generating structure without the use of wires or other connecting structures that penetrate an intervening wall or other structure. A tool a plurality of panels that define an enclosure. An atmospheric ionizer includes a source of energy disposed on one side of one of the panels of the tool. A capacitive coupling is connected to the source of energy. An ion-generating structure is disposed on an opposite side of the panel of the tool and is connected to the capacitive coupling. As a result, energy from the source of energy is supplied by the capacitive coupling through the panel of the tool to the ion-generating structure.

Abstract: A ergonomic customizeable user/computer interface system for wireless computer control. A hand-attachable user interface device transmits control information upon activation of switches on the interface device. A base interface device receives the transmissions, decodes the information and provides control signals to the computer. The interface system allows for security authorization control and multiple computer or LAN operations with each user interface device. Greater functionality is provided by the use of personality modules in the user interface device for different modes of operation.
