  • Patent number: 7449667
    Abstract: Light from a plurality of light sources is combined in a beam combiner. Photo-sensors are used to sense the intensity of each light source. Signals from the photo-sensors may be used to control the intensity of the light sources. The photo-sensors can be located in the beam combiner or located in the fringe of a collimated beam produced by the beam combiner. The illumination system has application in laser-scanning micro-projectors, for example.

  • Patent number: 7405384
    Abstract: A method and apparatus for controlling light intensity from two or more light sources. A timing scheme is used to modulate the light sources. Light from the light sources is combined to form a beam and a photo-sensor senses the beam. In a time interval when only one of the light sources is activated, the signal from the photo-sensor is monitored and used in a feedback control circuit to control the active light source.

  • Patent number: 7399656
    Abstract: Organic field effect transistors (OFETs) can be created rapidly and at low cost on organic films by using a multilayer film (202) that has an electrically conducting layer (204, 206) on each side of a dielectric core. The electrically conducting layer is patterned to form gate electrodes (214), and a polymer film (223) is attached onto the gate electrode side of the multilayer dielectric film, using heat and pressure (225) or an adhesive layer (228). A source electrode and a drain electrode (236) are then fashioned on the remaining side of the multilayer dielectric film, and an organic semiconductor (247) is deposited over the source and drain electrodes, so as to fill the gap between the source and drain electrodes and touch a portion of the dielectric film to create an organic field effect transistor.

  • Publication number: 20080144183
    Abstract: A handheld electronic device (100), e.g., cellular telephone handset, is provided with a color laser projector system (300) that includes an optics module (112) includes a large green laser module (316) and smaller red (314) and blue (318) laser modules in a compact arrangement in which the red (314) and blue (318) laser module are arrange within a dimensional extent D1 of the green laser module (316) in a direction that is perpendicular to a direction in which a green laser beam (426) is emitted. The optics module (112) uses a single photo-detector 328 to sense the intensity of laser beams emitted by the three laser modules (314, 316, 318). A prism can be used to direct light to a bare chip (804) photo-detector (328). Alternatively, a right angle mounted surface mount photo-detector (328) can be used.

  • Publication number: 20080106493
    Abstract: A laser image projector display system (200) includes laser operating electronics (208, 210, 212, 400, 500, 700) that selectively operates a laser diode at a bias that is low enough to save energy based on analysis pixel brightness values. The laser bias may be high enough that laser can be transitioned to a lasing state in time to display a pixel, or the system can “look ahead” into a stream of pixels and adjust the bias in advance.

  • Patent number: 7224512
    Abstract: A microelectromechanical systems (MEMS) apparatus (100) having a footprint of about 1 to 10 millimeters by about 1 to 10 millimeters comprises a movable member (101) that can be stopped at either of at least two positions by electrically neutral stops (105, 107). Depending upon the needs of a given application, these stops may all be fabricated using materials deposition and removal techniques or some, though not all, may comprise an attached component.
