摘要： In an embodiment, a stage system calibration method includes moving the stage relative to an encoder grid in response to a setpoint signal and measuring a position of the stage by a sensor head cooperating with the encoder grid. The position of the stage is controlled by a stage controller. A signal representative of a difference between the setpoint signal and the position of the stage as measured by the sensor head is registered. The stage system is calibrated from the registered signal representative of the difference.

The assembly includes an adapter plate that is adhered, clipped or otherwise affixed to the exhaust port, and a filter carrier that is removably attached to the base. The filter is preferably affixed as a unit to the filter carrier so that the entire filter/carrier unit can be replaced at once. The adapter base can also be used as an attachment for other accessories.

摘要： An electronic control system for a vacuum cleaner is provided that supports two-way communications between a microcontroller in the handle of the vacuum cleaner and a suction motor and various sensors in the canister of the vacuum cleaner. The vacuum cleaner may be placed in one of two user-selectable bag change modes. In a maximum suction bag change mode, the electronic control system of vacuum cleaner will shut off the vacuum cleaner when the vacuum cleaner bag has filled and the suction power of the unit has been degraded as a result. If the maximum fill bag change mode is selected, the electronic control system will shut off the vacuum cleaner only after the bag has filled to the maximum extent allowable. The control system has indicator lights to display to the user whether the maximum suction or the maximum fill mode has been selected. The control system also has an optical dust sensor based on one-piece lens units located in the vacuum cleaner handle for monitoring the frequency with which dust particles flow into the vacuum cleaner. The control system can automatically adjust the power setting of the vacuum cleaner based on the measured frequency.

摘要： A "universal" end fitting for a central vacuum cleaner hose, having a reversible electrical connector body that can be reversed without being disconnected from the end fitting, and which accordingly need not be realigned after being reversed, is provided. The connector body is permanently but rotatably affixed to the end fitting. Because it is permanently affixed, the connector body need not be realigned after being rotated to a new position.

摘要： A canister-type vacuum cleaner is provided in which various electrical functions of the vacuum cleaner may be controlled by the user with controls on the hose handle, whether the hose is attached to the suction port or the blowport. The primary exhaust port is located substantially toward the front of the vacuum cleaner body. During normal operation, air is directed from the hose through the suction port and the motor, toward the back of the vacuum cleaner, and then redirected to the front of the vacuum cleaner, where it exits from the primary exhaust port. The vacuum cleaner is also provided with a reduced wheelbase, for greater maneuverability. Two wheels are mounted on the underside of the vacuum cleaner body, near the vacuum cleaner's center of gravity, and a caster is mounted near the front of the vacuum cleaner. The vacuum cleaner can therefore be rotated about an axis passing adjacent the cleaner's center of gravity and perpendicular to the surface being cleaned, as well as an axis passing between the two wheels. Additional casters may be mounted on the underside and toward the back of the vacuum cleaner body, for additional stability.

摘要翻译：提供了一种罐型真空吸尘器，其中真空吸尘器的各种电气功能可由用户通过软管手柄上的控制来控制，无论软管是连接到吸入口还是吹气口。主排气口基本上位于真空吸尘器主体的前部。在正常操作期间，空气从软管通过吸入口和电动机朝着真空吸尘器的背面引导，然后被重定向到真空吸尘器的前面，在那里它从主排气口离开。真空吸尘器还具有减小的轴距，以提高机动性。两个轮子安装在真空吸尘器主体的下侧，靠近真空吸尘器的重心，脚轮安装在吸尘器前部附近。因此，真空吸尘器可以围绕穿过清洁器重心并垂直于被清洁的表面的轴线以及在两个车轮之间通过的轴线旋转。额外的脚轮可以安装在下侧并朝向真空吸尘器主体的后部，以获得更多的稳定性。
