  • Publication number: 20240073383
    Abstract: An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.

  • Patent number: 5294276
    Abstract: A process of making a paint roller with a foldable end comprising the steps of: securing a paint-roller support core to a paint-roller pad and then removing a portion of the core secured to the paint-roller pad. If multiple paint rollers are being made, one cuts the paint-roller pad and support core into multiple segments with the cut ends of the segmented paint-roller pad and core coextensive with each other. Next, one removes a portion of the ends of the support core without removing the paint-roller pad extending over the support core to leave a paint roller with an unsupported free pad end that is folded over the end of the core of the paint roller to provide full corner painting abilities. The paint roller with a covered end can be rotatably mounted on different types of paint-roller frames.

  • Patent number: 5264177
    Abstract: An open and shut molding method of making a paint roller bearing with offsetting core support surface for use in paint roller applicators that permit the user to change a paint roller quickly and efficiently on a paint roller applicator by bringing together a first mold and a second mold until a portion of the molds contact each other to thereby provide central regions in the mold cavity to exclude moldable material therefrom and then flowing a moldable plastic material into the mold cavity formed between the first mold and the second mold and separating the first mold from the second mold to enable removable of a ready to use molded one piece paint roller bearing housing having a central opening extending therethrough for inserting of a shaft therein for rotatable supporting the ready to use paint roller bearing housing thereon.

  • Patent number: 5261142
    Abstract: A paint roller frame having a wire coil female thread for attaching a plurality of different handles thereto. The wire coil female thread is formed directly in the wire frame that is used to support the roller. The wire coil female thread locks onto the rigid male threads of a handle and onto the handle to prevent accidental loosening and to also permit the user to completely replace the handle of the paint roller. The helical wire coil female thread is made of a resilient metal wire with sufficient rigidity to permits firm but yieldable direct transfer of pressure to the paint roller from a longer extension handle rather than through a permanent handle mounted directly on the wire frame. An extension member on the end of wire coil female thread enables a user to remove a handle from the wire paint roller frame without the use of a tool.

  • Patent number: 5210899
    Abstract: A paint roller bearing with offsetting core support surface for use in small diameter paint roller applicators that permit the user to change a paint roller quickly and efficiently on a paint roller applicator, with the bearing having an axle-engaging member that clamps to the axle of a paint roller frame to rotatably secure the bearing to the axle of a paint roller frame. The paint roller bearing offset surfaces permit molding the bearing using in inexpensive open and shut molding process while still providing a central opening in the bearing. An alternative embodiment includes friction ridges to hold a paint roller core on the bearing.

  • Patent number: 4896394
    Abstract: An insert is disclosed for a tool having a handle extending from a first end adjacent to a free second end. The handle has a hollow bore extending therethrough with an axis of the bore generally aligned with an axis of the handle. The insert includes a body having a longitudinal axis and sized to be inserted within the bore at the free end and moved through the bore to an inserted position adjacent the first end. The longitudinal axis is disposed parallel to the bore axis when the body is in the inserted position. An anchor is provided for fixing the body in the inserted position. The body in the inserted position presents a first surface opposing the bore axis. The first surface is provided with female threads selected to threadedly engage male threads on an end of an extension pole sized to be received within the bore.
