  • Patent number: 8913003
    Abstract: Methods and apparatuses for a free-space multi-dimensional absolute pointer using a projection marker system are described herein. In one embodiment, a presentation system includes, but is not limited to, a projection-based marker apparatus to project one or more optical spots on a display surface for displaying machine generated content capable of being manipulated via a cursor of a pointing device, a handheld device to wirelessly capture the projected optical spots from the display surface, and a control unit communicatively coupled to the projection-based marker apparatus and the handheld device to determine coordinates of the cursor based on characteristics of the captured light spots. Other methods and apparatuses are also described.

  • Patent number: 8907889
    Abstract: A method is described that involves identifying one or more images of respective one or more fixed markers. Each marker is positioned on or proximate to a display. The images appear on a pixilated sensor within a handheld device. The method also involves determining a location on, or proximate to, the display where the handheld device was pointed during the identifying. The method also involves sending from the handheld device information derived from the identifying of the one or more images of respective one or more fixed markers. The method also involves triggering action taken by electronic equipment circuitry in response to the handheld device's sending of a signal to indicate the action is desired.

  • Publication number: 20120275929
    Abstract: A fluid conveyance system includes a flow passage and a cavity adjacent a side of the flow passage. A wall of the passage includes a flexible section that separates the cavity from the flow passage. The cavity contains a ferrofluidic material. The system further includes at least one magnetic field source positioned adjacent the flow channel. The magnetic field source is operable to move the ferrofluidic material in the cavity to exert a pressure on the flexible section and displace the flexible section into the flow passage to alter the flow of material through the passage. A method of collecting components from a sample volume includes the steps of distributing magnetic particles into the sample volume, capturing the components from the sample volume, and applying a magnetic field to the sample volume to control directional flow of the sample volume.

  • Publication number: 20060158443
    Abstract: A spatial light modulator may be adapted to receive bi-directional drive signals. The spatial light modulator may include a plurality of pixel elements having individual first electrodes and a common electrode providing a second electrode for each of the pixel elements. The pixel elements may be adapted to change between a first state and a second state in accordance with signals applied thereto, and the bi-directional drive signals may include at least a first drive signal and a second drive signal. Both drive signals are applied to change the pixel elements from the first state to the second state and from the second state to the first state.
