A dishwasher is provided. The dishwasher (100) comprises: a washing fluid conduit system (118) comprising a plurality of washing fluid supply conduits, each washing fluid supply conduit for supplying washing fluid to at least one corresponding component of the dishwasher; a sump (114) for collecting the washing fluid, the sump comprising a plurality of sump outlets (138, 140, 142), each sump outlet for a corresponding washing fluid supply conduit of the plurality of washing fluid supply conduits; a pump (116) for pumping wash fluid from the sump to the wash fluid conduit system; a flow controller assembly operable to selectively enable flow of wash fluid from the sump to selected one or more wash fluid supply conduits. The flow controller assembly includes a flat circular flow diverter (152), the flat circular flow diverter including a plurality of diverter apertures (153); a positioning system configured to rotate the flow diverter relative to the sump outlets across a plurality of predetermined diverter positions, each diverter position providing alignment between one or more diverter apertures and one or more respective sump outlets, thus, washing fluid can flow from each of the one or more sump outlets aligned with the one or more diverter orifices to a corresponding washing fluid supply conduit. The positioning system comprises: a plurality of cam elements (C (i)) coupled to the flow diverter, each cam element being associated with a corresponding predetermined diverter position, each cam element extending along a corresponding arc of the flow diverter, the plurality of cam elements comprising a reference cam element C (1), the arc length of the reference cam element is different from that of other cam elements in the plurality of cam elements; a motor (156) configured to rotate the flow diverter; a cam follower system (180) comprising cam follower elements (182) configured to mechanically interact with the cam elements and to interact with a detection switch (184), a detection switch coupled to the cam follower element so as to switch the detection switch to a first state when the cam follower element mechanically interacts with the cam element, and to switch the detection switch to a second state when the cam follower element does not mechanically interact with the cam element; a control unit (125) configured to evaluate a position of the flow diverter among the predetermined diverter positions and to drive the motor in accordance with the evaluated position, the control unit is configured to evaluate said position of the flow diverter by: evaluating a position corresponding to a reference predetermined diverter position associated with the reference cam element of the predetermined diverter positions based on a duration of an interaction interval in which the detection switch is in the first state; and evaluating a position corresponding to a predetermined diverter position different from the reference diverter position among the predetermined diverter positions by counting a number of times the detection switch transitions to a selected state between the first state and the second state after evaluating the reference diverter position.

This utility model relates to the field of sliding door technology, specifically to a sealed sliding door structure and device, including a door frame and a door panel that moves parallel to the door frame along the X-axis. A cam follower is provided on the door panel and is movably connected to the door frame. A guide groove is provided on the door frame near the door panel to guide the door panel's movement along the X-axis. At least one sealing section oblique to the X-axis is provided in the travel of the guide groove, causing the door panel to simultaneously displace in the Z-axis direction. Because the guide groove also includes an oblique sealing section in its sliding travel, when the door panel moves to the sealing section, the door, guided by the groove, will not only move along the X-axis but also displace in the Z-axis direction. This Z-axis displacement causes the door panel to move closer to the door opening of the device, forcing the sealing strip on the door panel to be compressed, thereby improving the sealing between the door opening and the door panel.

A protective cover for an insertion probe of a medical instrument. The cover contains a flexible tubular body that compliments the probe geometry and a radially disposed flange that surrounds the proximal end of the body. A series of snap-on fasteners removably connect the cover to the instrument. A camming surface is located on the outer face of the flange which coacts with a cam follower that is movably mounted upon the instrument to flex the cover sufficiently to open the fastener and release the cover from the instrument and move the cover axially toward the distal end of the tip.

The present application relates to the field of battery equipment manufacturing, in particular to a square case battery negative pressure formation equipment capable of automatically changing type. The detection assembly comprises a positive probe mounting plate, a negative probe mounting plate and a suction nozzle mounting plate. The positive probe mounting plate is provided with positive probes, the negative probe mounting plate is provided with negative probes, and the suction nozzle mounting plate is provided with negative pressure suction nozzles. The positive probe mounting plate, the negative probe mounting plate and the suction nozzle mounting plate are respectively provided with connecting blocks on both sides, and the connecting blocks are provided with cam followers. The positive probe mounting plate, the negative probe mounting plate and the suction nozzle mounting plate are installed on a guide rail mounting plate through guide rails, and the guide rail mounting plate is fixed on a fixed frame through a mounting connecting plate. The present application can meet the negative pressure formation requirements of different models of square case batteries, and has the characteristics of high docking precision and being suitable for mass production.

The invention relates to the technical field of medical equipment, in particular to structural design of an unpowered lower limb exoskeleton robot which comprises a cam driven spring mechanism (I), a thigh connecting rod mechanism (II) and a shank connecting rod mechanism (III). The device is characterized in that a connecting rod of a cam driven spring mechanism is connected with a thigh connecting rod mechanism through a fastening screw, the thigh connecting rod mechanism is connected with a shank connecting rod mechanism through a bolt, a sole block is connected with a shoe of a wearer through a belt, a heel is connected with a shank through a belt, and a seat connecting rod is connected with the waist through a belt. During weight-bearing walking, the exoskeleton can assist a wearer through hip joint abduction torque generated by a spring mechanism, and loads borne by the upper body and the lower body of the wearer can be relieved; the shank connecting rod mechanism and the thigh connecting rod mechanism are closed-loop connecting rod mechanisms connected through universal joints and move synchronously with ankle joints of the exoskeleton. In addition, the thigh connecting rod mechanism can transmit the weight of the load to the ground, and no burden is generated on the wearer.
