Abstract: In some embodiments, a sensor assembly for measuring a depth of insertion of a locking pin of a liner in a pin lock of a lower-limb prosthetic is provided. The sensor assembly comprises a base; a sensing element mounted to the base and having a hollow interior; and a housing that encloses at least the sensing element and includes means for coupling the sensor assembly to the lower-limb prosthetic in a position where the locking pin adapter of the lower-limb prosthetic is aligned with the hollow interior of the sensing clement. The sensing element is configured to generate a signal indicative of a size of a portion of the locking pin that is within the hollow interior of the sensing element.

Abstract: A cleaner head for a cleaning appliance including an agitator rotatable about an axis; a housing having a front side, a rear side, and first and second sides which extend between the front and rear sides, said housing defining a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet; and a spray nozzle device for spraying cleaning fluid onto the agitator in a direction towards the rear side of the housing, said spray nozzle device being fluidly connectable to a cleaning fluid supply tank of a cleaning apparatus.

Abstract: A cleaner head for a cleaning appliance, including an agitator rotatable about an axis; a housing having a front side, a rear side and first and second sides which extend between the front side and rear side, said housing at least partially defining a chamber. The chamber at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. The chamber includes an opening for permitting access to and removal of the agitator from the chamber and a cover cooperatively associated with the housing for permitting access to the chamber through the opening. The cover is movable to an agitator access position to permit the agitator to be removed from the chamber through the opening in a direction substantially orthogonal to the axis of the agitator and in a direction which is substantially parallel to a plane of the surface to be cleaned.

Abstract: A cleaner head for a cleaning appliance including a housing having a front side, a rear side, and first and second sides which extend between the front side and the rear side, the housing further including a floor facing surface which extends between the front side, rear side and first and second sides which, in use, faces a surface to be cleaned. A floor engaging device is connected to the floor facing surface of the housing and which extends laterally between the first and second sides of the housing, said floor engaging device including a first portion for absorbing liquid from a surface to be cleaned; and a second portion positioned closer to either a front side or a rear side of the housing, said second portion being relatively stiff compared to the first portion.

The housing defines a chamber which at least partially surrounds the agitator, the chamber having a dirty air inlet and a dirty air outlet. A wiper device which extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. A floor engaging device extends laterally between the first and second sides of the housing and is positioned on or adjacent the floor facing surface. The floor engaging device includes an absorbent portion. The wiper device and the floor engaging device are positioned rearwardly of the dirty air inlet.

Abstract: A surface cleaning device includes a body, a suction opening, a suction source, and a separation chamber. The body has a handle and a receptacle. The suction source is at least partially located within the body. The suction source is in fluid communication with the suction opening and is operable to draw a fluid mixture of liquid and air through the suction opening. Liquid is separated from the fluid mixture in the separation chamber. The separation chamber is coupled to the body for rotation relative to the receptacle about a rotational axis. The separation chamber includes an inlet in fluid communication with the suction opening, an outlet in fluid communication with the suction source, and a drainage outlet in fluid communication with the receptacle.
