Abstract:
A projection screen unit includes a first projection surface optimized for a predetermined range of ambient conditions and a second projection surface optimized for a second, different range of ambient conditions.
Abstract:
A printer having a head and a handle are disclosed. In one embodiment, the handle has a convex side and a concave side. In another embodiment, the head is pivotable relative to the handle.
Abstract:
A display of an embodiment of the invention includes a number of display modules that are interlockable to form the display. Each display module includes at least one user-viewable display element, at least one connector, and at least one receptor, which are disposed in the display module. Each of a number of pixels of the display corresponds to at least one of the display elements of each display module. The connectors of each display module at least receive power from and/or provide power to adjacent display modules. The receptors of each display module are receptive to connectors of other adjacent display modules.
Abstract:
A motor hub is disclosed. The motor hub comprises a housing for a motor. The housing is rotatable around an axis of rotation of the motor. The motor hub also has marks arranged on a surface of the housing, and spaces between the marks. The marks and spaces form a pattern readable for sensing a rotational speed of the motor.
Abstract:
An apparatus and method rotate a first contact (80, 180, 380) of a fluid supply body (70, 170) into contact with a second contact (40, 140, 340) of a fluid receiving device (22, 122, 322, 522).
Abstract:
A hydrogen generating apparatus includes a chemical reaction chamber, a chemical solution reservoir, an unpowered pressure-producing member for moving a chemical solution from the chemical solution reservoir to the chemical reaction chamber, and a catalyst bed in the chemical reaction chamber.

A hydrogen generating apparatus includes a chemical reaction chamber, a chemical solution reservoir, an unpowered pressure-producing member for moving a chemical solution from the chemical solution reservoir to the chemical reaction chamber, and a distributed catalyst bed about the chemical reaction chamber.
Abstract:
A sensor/switching device configuration that includes a substrate and at least one element imprinted on the substrate containing an electroconductive material.
Abstract:
A system includes a first token associated with a display device and configured to be selectively repositioned by a user with respect to the display device, the first token having at least one interactive module configured to interact with a second token. The system may include a plurality of modules, each of which is configured to be selectively attached to a token, each of the modules providing a different capability to the token when attached thereto. A display system includes a display device; a sensor for detecting tokens used with the display device; a controller communicatively coupled to the sensor and the display device; and a first token associated with the display device and including an optical sensor for receiving data from the display device. The controller is configured to drive the display device to simultaneously display an image and transfer data to the first token.
