  • Publication number: 20230113086
    Abstract: An adjustable sander having a body and a flexible base. The flexible base includes a first end and a second end spaced apart from one another. The first end and second end are each pivotally attached to the body. The flexible base is configured to move between a concave configuration, a neutral configuration, and a convex configuration relative to the body. The adjustable sander further includes a removable sanding surface affixed to a surface of the flexible base that is distal from the body. The adjustable sander also includes a locking mechanism configured to selectively hold the flexible base in a desired concave, neutral or convex configuration. The locking mechanism is characterized in that it includes an axial having a head and a shaft having a series of shaft notches.

  • Patent number: 10524590
    Abstract: A wrench support rack including a base, and at least one clamp assembly attached to the base and comprising a vertical stop spaced apart from a push member. The space in between the vertical stop and the push member forms a groove configured to receive a stem of a wrench. The vertical stop includes an upper ridge portion configured to engage a stem of a wrench and limit vertical movement of a wrench disposed in the groove. The push member includes an inward protrusion configured to press a stem of a wrench in to the vertical stop and limit horizontal movement of a wrench disposed in the groove.

  • Patent number: 8922225
    Abstract: A sensing pad includes a first sensing layer, a second sensing layer and a spacer layer. The second sensing layer has at least one second sparse sensing zone and at least one second dense sensing zone. The spacer layer is disposed between the first sensing layer and second sensing layer, and includes at least one high pressure spacer zone and at least one low pressure spacer zone. The second sensing layer is pressed downwards upon receiving a load to compress the spacer layer and contact the first sensing layer to generate electric connection, thereby detecting the pressed location. Through the dense sensing zone and sparse sensing zone distributed on the second sensing layer whether a person is lay on a bed can be judged to reduce faulty judgments, and the posture of the person can be detected to better understand conditions of the person lay on the bed.

  • Publication number: 20130052294
    Abstract: A method of making a molding tool includes: preparing an imprinting master having a surface relief pattern; applying a curable material on a flexible film; embossing the curable material on the flexible film using the imprinting master so as to transfer the surface relief pattern to the curable material; curing the embossed curable material so as to form a patterned-and-cured material; attaching and conforming the flexible film to a non-planar surface of a model; forming a thin metal film over the patterned-and-cured material; electroforming a metal layer over the thin metal film so as to form a molding tool of the metal layer; and removing the molding tool from the thin metal film.
