Abstract: A spark detector lens assembly is adapted to block energy from static electric discharges. The lens assembly includes a housing which receives a lens. The lens is adapted to pass infrared frequency energy therethrough. A conductive coating is disposed on one side of said lens, which is effective to block radio frequency energy but pass infrared frequency energy. The conductive coating may be electrically connected to an electrical ground path. The lens assembly is especially effective for preventing false alarms by shielding a spark detector from radio frequency energy radiated by static electric discharges.

Abstract: A method and system for controlling the firmness of an inflatable air mattress wherein an air blower supplies pressurized air to the inflatable chamber(s) of the mattress through a port containing a valve in response to a target fullness selected by the user, the blower operation being controlled by a processor having an array of blower speeds included in a computer readable medium blower so that the speeds are selected in response to the target value.

Abstract: A thin, portable, lightweight electronic name and address cardfile optionally including memo alarm, calendar and calculator functions, is provided with a contact and movement sensitive scrolling mechanism for sequentially advancing electronically simulated name and address cards in the style of bottom-attachable index cards. The scrolling function is accomplished by manipulating a graphic representation of a rotary actuator of the type provided on a mechanical rotary-type directory. The simulated card-flipping is accompanied by an artificial sound effect reminiscent of the expected sound of cards flipping. The device may be provided with holes positioned so as to render the device insertable within a loose-leaf ring-type binder notebook or personal organizer.
