Abstract: A surface cleaner system includes a base assembly having a housing movable along a surface, a pump supported by the housing and operable to pressurize a fluid, and a prime mover supported by the housing. The prime mover is coupled to the pump to drive the pump. The surface cleaner system also includes a spray assembly coupled to the housing. The spray assembly is operable to discharge fluid from the pump toward the surface. The surface cleaner system further includes a spray gun in fluid communication with the pump to receive pressurized fluid from the pump. The spray gun includes an outlet portion that is connectable to the base assembly to direct the pressurized fluid from the pump into the spray assembly. When the outlet portion is disconnected from the base assembly, the spray gun discharges the pressurized fluid from the pump toward the surface without directing the pressurized fluid into the spray assembly.

Abstract: This invention provides a support stand for portable electronic devices that is incorporated into a battery. The support stand is optionally detachable. When the support stand is closed, the electronic device fits into the hand or a belt holster in its normal fashion. When the support stand is open, the support stand allows the portable electronic device to rest at an angle relative to a horizontal surface. When applied to a cellular phone or two-way radio, the invention offers improved access to the display screen and microphone/speaker assembly, as well as offering improved antenna performance.

Abstract: An electronic device (100) includes at least L keys (114) and a processor (506) having at least M inputs (600). Upon actuation, each one of the at least L keys (114) toggles a unique combination of N inputs of the at least M inputs (600), where each unique combination is taken from all possible combinations thereof. The at least M inputs (600) are read by the processor (506) and compared to a plurality of predetermined key patterns (806). Upon a match between the at least M inputs (600) and one of the plurality of predetermined key patterns (806), a key actuation is detected and a predetermined function may be processed in response thereto. The processor (506) may ignore simultaneous key actuations where combinations of inputs greater than N are toggled.
