    Abstract: A MEMS optical display system includes an illumination source for providing illumination light, a collimating lens for receiving the illumination light and forming from it collimated illumination light, and a microlens array having an array of lenslets for receiving the illumination light from the collimating lens. The converging microlens array directs the illumination light through an array of pixel apertures in an aperture plate to a microelectrical mechanical reflector array positioned opposite the aperture plate. The microelectrical mechanical reflector array includes an array of microelectrical mechanical actuators that support reflectors in alignment with the array of pixel apertures and selectively orients the reflectors to direct the illumination light back through the pixel apertures (to form part of a display image) or against the aperture plate (to be blocked). The illumination light passing back through the pixel apertures passes through the microlens array and a beamsplitter to a display screen.

    Abstract: A unilateral in-plane thermal buckle-beam microelectrical mechanical actuator is formed on a planar substrate of semiconductor material, for example. The actuator includes first and second anchors secured to the substrate and a floating shuttle positioned movable parallel to the substrate. Symmetric first and second sets of elongated thermal half-beams are secured between the floating shuttle and the respective first and second anchors. The first and second anchors and the first and second sets of thermal half-beams are positioned along one side of the floating shuttle. The half-beams are formed of semiconductor material, such as polysilicon. A current source directs electrical current through the thermal half beams via the anchors to impart thermal expansion of the thermal half-beams and hence linear motion of the floating center beam generally parallel to the substrate. A floating cold beam connected between the shuttle and the substrate constrains and amplifies the motion of the shuttle in a predefined direction.

    Abstract: A digital panoramic camera system for producing digital panoramic images includes a camera body forming a linear optic path and which is rotatably mounted to a motor. An infrared cutoff filter is also provided along the optic path for filtering light which is then provided to a charge coupled device. The charge coupled device generates analog signals corresponding to color information transmitted by the light to an analog interface which tunes the analog signals. A series of pulses is provided to the motor and to an analog to digital converter, thereby synchronizing rotation of the camera body with the conversion of analog signals to digital signals within the converter. A digital interface unit is also provided which receives digital signals from the converter and provides converted digital signals to a computer for processing the signals into a digital panoramic image.

    Abstract: A microelectrical mechanical systems actuator that provides a long throw is disclosed. The actuator includes a drive mechanism that oscillates a pallet that is located between leg portions of a drive member. The pallet includes first and second rows of pallet teeth located along two opposite edges of the pallet. The drive member is slideably coupled to a substrate, and includes first and second rows of drive teeth that are located along two opposing drive margins of the drive member leg portions. The pallet teeth and the drive teeth are compatible so as to permit meshing engagement of the pallet teeth with the drive teeth. The pallet is arranged between the rows of drive teeth. When the pallet teeth are meshingly misaligned with respective drive teeth and the pallet is urged against the drive margin, the drive member is forced to move until the teeth meshingly engage. By arranging the pallet and drive teeth so that first and second respective sets of pallet and drive teeth can not simultaneously be in meshing alignment, the drive member may be incrementally moved by oscillating the pallet edges between the first and second drive margins. The shape of the pallet and drive teeth may be selected to control a step size of the movement increment and the force applied. Further, the pallet and drive teeth may be arranged so as to provide movement in one direction or two directions.

    Abstract: Moving a panel on a microelectromechanical system by generating a magnetic force that acts on the panel is disclosed. The panel is formed on, or coupled to, a substrate so as to be able to move between first and second positions. The panel includes an electrically conductive region, such as a metallic ring or sheet, or a doped polysilicon layer. An electrical coil is also located on the substrate and coupled to a power source that can generate time-varying current. When a time-varying current is conducted through the coil, a magnetic flux is generated in the coil that induces an electromotive force (emf) in the panel that, in turn, generates a magnetic flux having a direction that is opposite the magnetic flux in the coil. The opposing magnetic fluxes create a repulsive magnetic force that urges the panel to move away from the coil. A flat spring is provided to hold the panel in a desired position and provide a drag force on the panel as it moves.

    Abstract: A surgical simulator provides both visual and tactile feedback in order to realistically portray an actual surgical procedure. The visual feedback is provided through an SGI graphics computer which drives a monitor to display two images of an eye at slightly different perspectives. A set of optics, which preferably mimics an actual surgical microscope, combines the two images to form a stereo image of the eye. An instrument for simulating a surgical tool is connected through three sets of levers and hinges to three servo-motors which collectively generate a resistive force along any direction. The forces provided to the instrument are modeled after forces measured during an actual procedure and therefore accurately simulate the feel of a surgical procedure. The position and orientation of the instrument is transmitted to the SGI graphics computer which manipulates the eye based upon the position and motion of the instrument and updates the image of the eye to display a manipulated eye. The position of the instrument is also relayed to a second processing unit which provides the tactile feedback based upon the state of the instrument.
