Abstract: A floor treatment device may include a body portion comprising one or more pumps, one or more spray outlets, and one or more reservoir receptacles configured to receive one or more reservoirs. The one or more pumps are operable to be activated and direct liquids to the spray outlets. The device may include swappable heads, each comprising a body connector configured to mate with a head connector of the body portion. In an embodiment, the head connector may include a sensor system and a controller communicatively connected to the sensor system. When one of swappable heads is connected to the body portion, the sensor system is configured to detect the identity of the swappable heads connected, and the controller is configured to selectively activate, based on the identity of the swappable heads, at least one of the one or more pumps.

Abstract: Methods, systems and computer readable media for visual schedule building are disclosed.

Abstract: A clinical diagnostic sample analyzer for analyzing a sample of a patient is disclosed. The analyzer includes a telescoping closed-tube sampling assembly with a sample probe concentrically housed within a piercing probe and a venting mechanism. The closed-tube sampling assembly is used for aspirating a sample from a sample tube for analysis by a clinical diagnostic sample analyzer.

Abstract: A vacuum system comprises, as an integral assembly, a vacuum pump with drive motor, a purge valve, a roughing valve and an electronic control module. A cryogenic vacuum pump and a turbomolecular vacuum pump are disclosed. The control module has a programmed processor for controlling the motor and valves and is user programmable for establishing specific control sequences. The integral electronic control module is removable from the assembly and is connected to the other devices through a common connector assembly. In the turbomolecular pump system proper introduction of a purge gas through the purge valve is detected by detecting the current load on the pump drive or by detecting foreline pressure. To test the purge gas status, the purge valve may be closed and then opened as drive current or pressure is monitored. After power failure, the controller will continue normal drive of the turbomolecular pump so long as the speed of the pump has remained above a threshold value.

Abstract: A vacuum roller includes a roller having transverse holes and surface holes, in which each of the surface holes intersects with at least one of the transverse holes. A cap mates to a portion of the roller where the transverse holes are exposed. The cap has a cavity that aligns to at least one of the transverse holes and remains substantially stationary during rotation of the roller. A vacuum device evacuates the cavity.

Abstract: A linear drive motor of a cryogenic refrigerator, where a reciprocating armature is coupled to a piston which alternately compresses and expands a gaseous fluid in a thermodynamic cycle. The piston has a clearance seal and is attached at one end to a flexible coupling to reduce cross-bearing loads exerted by the piston along the clearance seal. A displacer assembly of the cryogenic refrigerator employs a displacer piston that reciprocates along a clearance seal. The displacer piston is coupled to the displacer cylinder and/or the armature of a displacer drive motor by a flexible coupling that reduces radial forces exerted by the displacer piston on the clearance seal.
