Abstract: A breast pump assembly comprising: (a) a breast milk caddy including a frame having an arm repositionable with respect to a handle between a folded position and an extended position, and a milk extraction device repositionably mounted to the arm of the frame, the milk extraction device including complementary top and bottom components removably mounted to one another, the bottom component including a breast milk extraction vessel, and the top component including a breast cone having an inlet for receiving a woman's breast and an outlet in communication with the extraction vessel for storing extracted milk, the top component also including a conduit for delivering suction to the inlet of the breast cone; (b) a breast pump including a fluid pump including an inlet and an outlet, where the fluid pump generates suction at the inlet during operation of the fluid pump, and a control system in electrical communication with the fluid pump for controlling operation of the fluid pump, the control system including a sof

Abstract: A level comprises a body, a body orientation detector, a laser beam source, a laser beam configuring lens, and a manually engageable lens switch. The body orientation indicator is carried by the body and constructed and arranged to indicate an orientation of the body. The laser beam source is carried by the body and constructed and arranged to emit a laser beam from the body to a location on a surface remote from the body, the laser beam being directed at a predetermined orientation with respect to the body to interrelate the orientation of the body with respect to the location on the surface remote from the body. The laser beam configuring lens assembly is carried by the body and movable between a first position and a second position with respect to the laser beam source.

Abstract: A hidden object sensor is described which senses and locates hidden objects hidden behind a surface of an architectural structure. The sensor includes sensing elements for sensing live wires behind the accessible surface, and separate sensing elements for respectively sensing metal and non-metallic objects behind the tested surface. A microprocessor alternates between the use of the various sensing elements and their associated circuits to detect live wires, metal objects, or wood studs. Visible and audible indicators are provided for indicating the device's mode of operation and the locations of sensed hidden objects.

A microprocessor alternates between the use of the various sensing elements and their associated circuits to detect live wires, metal objects, or wood studs. Visible and audible indicators are provided for indicating the device's mode of operation and the locations of sensed hidden objects. If a live wire is sensed, the processor may preclude an indication of a metal object or wood stud.

Abstract: A measuring device includes a housing, a distance measuring apparatus carried on the housing, one or more housing orientation indicators, and a focused light beam source. Using the housing orientation indicators, the housing can be properly oriented so that a focused light beam emitted by the focused light beam source will illuminate a point on a remote surface to accurately transfer the position of the housing to the remote surface.
