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： An arrangement (apparatus and method) using fuzzy logic for determining the ratios of barcode elements with respect to a reference barcode element. A barcode interface outputs width data for the reference barcode element and the other barcode elements of the barcode pattern in accordance with a predetermined barcode format. A latch array latches the width data of the reference barcode element and supplies the reference width data and a divided value of the reference width data to a fuzzy microcontroller as center and width data for a fuzzy membership function, respectively. The latch array also latches the barcode element width data from the barcode interface, divides the barcode element width data by a set of predetermined ratios, and outputs the quotient data to the fuzzy microcontroller. Each quotient data corresponding to one of the ratios is fuzzified by determining the distance of the crisp input from the center of the membership function and linearly complementing the distance with respect to the width of the membership function. The quotient data that has the highest membership value is deemed to correspond to the winning ratio. The fuzzy microcontroller uses rule-based logic that enables code recognition of the barcode scanner on the basis of successive determined ratios, as well as control of external devices in response to the determined ratios.

摘要： A vacuum cleaner and method for determining the kind of floor surface being cleaned by a vacuum cleaner wherein dust amount per unit interval is detected and dust detection change patterns are analyzed for determining floor type. This analysis is based on the following assumptions: smooth and carpet surfaces can be distinguished by dust detection patterns for an interval of several seconds. On the smooth surface, almost all of the dust at one place is picked up during an early stage of the interval. On the other hand, on a carpet floor, dust is picked up continuously. On a new carpet, many piles detach during vacuuming. Thus, if dust detection is continuous over several seconds it may be assumed that, the carpet is a new carpet.

摘要： A particle monitoring device located in a line carrying a moving fluid, as air, containing particles. The device has a particle sensing member providing audio signals that are in proportion to the amount of particles moving with the fluid. The sensing member is a flexible sheet member closing an open end of a connector housing having a chamber. Particles that hit the active section of the sheet member produce an audio signal providing information feedback of the amount of particles moving with the fluid.

摘要： A particle flow monitor mounted on a housing having a passage for carrying moving fluid and particles produces audio signals that are in proportion to the amount of particles moving with the fluid. The monitor has a sensing unit having one or more enclosed chambers or cells closing an open end of the housing. A portion of the sensing unit is exposed to a flow chamber within the housing. Particles that impinge on the portion of the sensing unit produce an audio signal which provides audio information feedback as to the amount of particles moving with the fluid.

摘要： A particle monitoring device located in a line carrying a moving fluid, as air, containing particles. The device has a particle sensing member providing signals that are in direct proportion to the amount of particles in the moving fluid. The sensing member can be a flexible cover enclosing the large end of a housing having a side wall that increases in diameter as a function of distance from its inlet, as a funnel-shaped housing. Particles that hit the cover produce an audio signal providing information feedback of the amount of particles in the moving fluid.

摘要： A robot floor cleaning system features a mobile floor cleaning robot and an evacuation station. The robot includes: a chassis with at least one drive wheel operable to propel the robot across a floor surface; a cleaning bin disposed within the robot and arranged to receive debris ingested by the robot during cleaning; and a robot vacuum configured to pull debris into the cleaning bin from an opening on an underside of the robot. The evacuation station is configured to evacuate debris from the cleaning bin of the robot, and includes: a housing defining a platform arranged to receive the cleaning robot in a position in which the opening on the underside of the robot aligns with a suction opening defined in the platform; and an evacuation vacuum in fluid communication with the suction opening and operable to draw air into the evacuation station housing through the suction opening.
