  • Publication number: 20150309588
    Abstract: An ultra compact mobile keyboard. The keyboard has a plurality of mechanical keys suitable for touch typing. Each such key has a travel distance sufficient to provide a touch type feel and a rigid cap for crisp actuation by a user. The keyboard has a deployed configuration for touch-typing use and a collapsed configuration for transport and storage. In the collapsed configuration, the keyboard fits within bounding volume of less than 180 cubic centimeters.
    Type: Application

  • Publication number: 20100141960
    Abstract: A method and apparatus to digitize three-dimensional objects. A projection assembly is retained in fixed relation to an imaging assembly. The projection assembly projects a fixed gradient light pattern into a focal zone of the imaging assembly. The imaging assembly integrates the illumination over time such that the fixed gradient reveals the features of the three dimensional object.

  • Patent number: 6980302
    Abstract: A method and apparatus capable of using two or more capture methods to create three-dimensional representations of a target captured. Elements of the three-dimensional digital representation generated from the plural capture method are combined to yield a single digital three-dimensional representation having improved quality.

  • Patent number: 6530550
    Abstract: A method and apparatus for rotating an object. An upper unit is rotatably mounted on a base. A drive mechanism is mounted within the base so as to engage and drive rotation of the upper unit. A processor within the base controls the drive mechanism to achieve desirable acceleration characteristics during a cycle to reduce disturbances of an object rotated.

  • Patent number: 4088891
    Abstract: An electrostatic aperture printer employing a gating mask placed between a source of ions and a charge receiving member to generate imagery consisting of aggregations of elemental dots or line segments formed in response to electronic control signals wherein the improvement lies in electrically biasing the mask or mask segments in such a way that the functions of ion collection and control are combined in the region between the mask and a charge receptor backing electrode via the establishment of appropriate transmission or blocking fields. Further electrostatic printing improvements incorporated are the development of useful charge receptor holddown forces via static or rolling backing electrode structures designed to make constructive use of the longitudinal tension normally developed in receptor web handling, and enhanced ion transmission achieved by means of shaped aplanar mask structures incorporating zones fabricated from insulating material.
