The capacity for removing contaminants refers to capacity for scraping contaminants adhering to the one surface of the substrate, and suction marks, contact marks and the like remaining on the one surface of the substrate by polishing. It is possible to change the capacity for removing contaminants by adjusting a pushing force exerted on the one surface of the substrate from the polishing head, for example.

  • Patent number: 11084642
    Abstract: An inflation device for pressurized inflation of an un-inflated package, the package comprising two layers, which are generally flat prior to inflation, and an inflation opening, the inflation device comprising an inflation tool, for contacting the package at the inflation opening to inflate the package through the inflation opening using inflation fluid from a pressure source, the inflation tool having an enclosing surface to enclose the inflation opening externally of the package. The inflation tool is larger than the inflation opening so as to ensure that the inflation opening is actually enclosed.

  • Patent number: 11080576
    Abstract: A system and method offer a garment provider the ability to automatically scan and track garments at multiple locations without adding processing stations. Various embodiments of this invention allow garment providers to achieve greater processing efficiencies and implement reporting and tracking protocols to provide customers with important data regarding garments in their program with a higher level of confidence. This invention is implemented in various embodiments with a system and/or method for tracking clothes and other textile articles utilizing multiple RFID reading modules throughout the system or method to achieve greater accuracy for reporting and tracking the items. One aspect of various embodiments of this invention is the reading of RFID tags on articles being dried in a commercial dryer. The movement of the articles induced by the action of the dryer provides for increased exposure of the RFID tags on the articles for more reliable detection.

  • Patent number: 11045065
    Abstract: A method of operating a dishwashing appliance includes filling the sump of the dishwashing appliance with an initial fill of water of a current operational cycle and measuring a temperature of the initial fill of water. The method also includes comparing the temperature of the initial fill of water to a reference temperature and calculating an energy demand for the dishwashing appliance to heat the initial fill of water to the reference temperature based on a heat rise rate. Based on the calculated energy demand, for example based on a comparison of the calculated energy demand with a predetermined energy demand for an external heating unit, the dishwashing appliance decides whether to heat the initial fill. The heat rise rate may be calculated during a characterization of the dishwashing appliance prior to the current operational cycle.

  • Patent number: 11007645
    Abstract: A cleaning device includes: a range finding sensor; an acquisition unit which acquires a map of an environment including object position information, and a first path where the cleaning device is to move in the environment; an identification unit which identifies a first path partial path; a converter which converts the partial path into a differently-shaped path to generate a second path; and a motor controller which causes the cleaning device to move along the second path. The identification unit sets a region, on the map, where the range finding sensor can perform range finding from start and end points of a portion of the first path, and identifies the portion as the partial path when only one or more straight lines which traverse the region and are parallel to a line segment toward the end point from the start point are represented as the object in the region set.

    Abstract: A childcare support service offering system includes a terminal and a server. The terminal includes a camera and performs operation control and processing of transmitting terminal usage situation data including image data acquired by being picked up by the camera to the server. The server performs image analysis on the received image data, recognizes the user that watches the terminal, judges a gaze of the recognized user, and judges a degree of interest for the terminal based on the gaze. When the judged degree of interest becomes equal to or less than a predetermined threshold value, the server transmits a changing instruction for causing an operation in the terminal to be changed to another operation to the terminal.
