A positioning system including a light source, infrared beacon and controller. The infrared beacon broadcasts a signal. The positioning system may be used with a portable computing device.
摘要:
A physical positioning system for a portable computing device equipped with an infrared receiver includes a light source removably attachable to a lighting fixture that supplies electrical power at a determined voltage. The light source has an attached voltage converter to provide a reduced supplied voltage. An infrared beacon is powered at the reduced supplied voltage through an electrical connection to the voltage converter. The infrared beacon broadcasts a data signal representative of a physical location.
摘要:
A display array element including a substrate, a prism rotatable relative to the substrate, and a fluid conduit defined in part by the substrate. The prism has a first viewable surface having fist reflectance characteristics and a second viewable surface having second reflectance characteristics. The fluid conduit permits direction of fluid against the prism to rotate the prism to selectively allow viewing of one of the first and second viewable surfaces.
摘要:
A bistable flap array display in which flaps selectively cover portions of a background substrate in response to fluid flow and a flap catchment mechanism, each flap rendering at least one pixel of the display. The catchment mechanism can be electrostatically based and the fluid can reduce the charge required to operate the catchment mechanism by creating a partial vacuum that lifts the flaps until the flow can impinge on the flap directly.
摘要:
A Unistrokes symbollogy in which strokes of like profile (i.e., strokes that are distinguished from each other by their rotational orientation) are rotationally offset from each other by at least 90° is provided. This provides a sufficient tolerance for disambiguating these strokes when they are written into hand-held pen computers and the like by users having widely divergent hand writing styles.

摘要:
The present invention describes a method for superimposing prespecified locational, environmental, and contextual controls on user interactions, including interactions of mobile users, with computational resources. A system is described for electronically monitoring contextual information concerning users and machines, including state and locational information including proximity. Interaction policies, including user specified interaction policies, may be registered on an identifiable address path. Methods are described for detecting, selecting and controlling computercontrolled devices, based on the proximity of the device to the user, the current context of the user, the location of other nearby users and devices, and the current state of the devices. Temporary transfer of control, including exclusive control, of particular computers and computer controlled devices to individual users based on the context and environment in proximity to those computing devices is also described.
