Patents by Inventor Ralph S. Hanseler

Ralph S. Hanseler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6232992
    Abstract: The invention involves a thermal imaging apparatus comprising a support for supporting a receiver material and a donor material in a superimposed relationship. The support includes a cylindrical drum having an inner circumference on which the receiver material is supported against in a bottom layer of the superimposed relationship and the donor material in a top layer of the superimposed relationship. An imaging unit thermally transfers an image from the donor material to the receiver material. The imaging unit is configured to thermally transfer an image by scanning energy beams across the donor material.
    Type: Grant

  • Patent number: 5598739
    Abstract: A linear motion drive apparatus uses a friction drive wheel to drive a carriage along two rails. The drive shaft of the friction wheel is supported by the carriage, and has a rotor of a pancake motor and an inertia wheel non-rotatably attached thereto. The stator is fixed to a wall of the carriage. The carriage is supported by recirculating ball bearings which are arranged with permanent magnets to urge the friction wheel into engagement with the flat rail. A slip detection and correction system has first encoder mounted on the drive shaft to produce a signal representing the rotational position of the shaft, and a second encoder mounted on the carriage to produce a signal representing the position of the carriage with respect to the rails. The motor is responsive to the signals to compensate for detected slippage.

  • Patent number: 5451777
    Abstract: A scanning apparatus is disclosed in an imagesetter with an internal drum recording surface, having an improved carriage system which is self-propelled and carries scanning optics for recording an image including a spin motor/mirror, a laser diode, and a focusing lens. The drive system is mounted to the carriage to allow the carriage to move linearly inside the drum as a self-propelled direct drive. An electronic control device mounted on the carriage provides precision motion control of the carriage.
