Embodiments of a token configured to interact are disclosed.

Token configured to interact

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.

An apparatus and method rotate a first contact () of a fluid supply body () into contact with a second contact () of a fluid receiving device ().

Fluid supply contact

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.

Printing device handle

Embodiments including a charge responsive optical material are disclosed.

Optical modulation system

Methods and apparatuses for forming components or circuits by ejecting a fluid including materials in a single ligament are disclosed.

Apparatus for forming a circuit

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.

Display with interlockable display modules

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.

Hydrogen generating apparatus

A projection system includes a cabinet having a surface with an aperture therein, a projector disposed within the cabinet, adapted to project light through the aperture in the surface of the cabinet, and a lens disposed in the aperture to project the light onto a screen disposed generally non-parallel to the cabinet surface having the aperture.

Cabinet-surface-mounted projection lens and methods

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.

Marked hub for sensing motor speed

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.

Solid freeform fabrication systems, powder supply bins for solid freeform fabrication systems, and methods of solid freeform fabrication are disclosed. One exemplary solid freeform fabrication system includes a powder supply bin, a build bin, a roller, and a print head disposed above the build bin that deposits a binder onto the powder in the build bin in a preselected pattern, the supply bin and/or the build bin translating in a x- and/or y-direction relative to the print head.

Systems and methods of solid freeform fabrication with translating powder bins

A gas generation system includes a chemical reactor configured to produce a gas from a continuous flow of aqueous solution, and includes a pump configured to control the flow of the aqueous solution through the chemical reactor to control a production rate of the gas.

Gas generation system

An enhanced-contrast projection screen and method of controlling such screens are disclosed. An embodiment of a dynamic projection screen includes a passive layer and at least one active layer. The active layer is superimposed on at least a portion of the passive layer and is adapted to selectively toggle between being transparent and being opaque. A method of controlling such a screen includes determining desired dimensions of a reflective region, and activating at least a portion of an active layer superimposed on at least a portion of a passive layer. The active layer is adapted to selectively toggle between being transparent and opaque.

Dynamic projection screen

A sensor/switching device configuration that includes a substrate and at least one element imprinted on the substrate containing an electroconductive material.
