  • Publication number: 20070146122
    Abstract: A window-attached alerting device (10) having an electronics circuit (12) that is enclosed within an alerting device enclosure (40) that includes an outer side (42) and an inner side (44). The outer side (42) is removably attached to an inner surface (62) of a windowpane (60) that is attached to a building. Since the enclosure (40) is attached to the inside of the building, the enclosure is not exposed to inclement weather or to theft. The outer side (42) of the enclosure (40) is visible through the windowpane (60) and includes indicia (52) in the form of a target (54) or the like that is positioned to encompass an electrode (22). When a person places his/her finger or hand proximate to the target (54) the electrode, in combination with the electronics circuit (12), produces an alerting device signal 31 that can be easily heard within the building.

  • Publication number: 20060181154
    Abstract: A combination of a capacitance-sensing light switch (sensing cube (1)) and a cover-plate mounting system (2), (3), (4) significantly improving on existing light switches. The capacitance-sensing switch is electrically isolated in an epoxy filled sensing cube (1) yet is compatible with cover-plates (4) made from materials with a wide range of dielectric constants; stone, wood, tile, plastic and metal. The sensing cube (1) integrates into the cube housing (2) creating a package similar in size to the mechanical switches it replaces. The invention eliminates the holes in the cover-plate for the switch and the mounting screws. The sensing cube (1) is activated through the cover-plate (4) by a change in its capacitance when the cover-plate (4) is touched. The cover-plate (4) is connected to the mounting system mechanically and pulled into position using a mechanical spring or friction lever.
