  • Patent number: 8208759
    Abstract: An image system comprises a light valve and an image capturing unit. The light valve comprises an array of individually addressable pixels capable of generating an image. The image capturing unit comprises a detector having an array of detector pixels capable of capturing images. The detector pixels are correlated with the light valve pixels.
    Type: Grant

  • Patent number: 6208151
    Abstract: The improved method for microscopic measurement of electrical characteristics comprises a standard atomic force microscope (AFM). The AFM includes a pointed, conductively coated tip attached to one end of a softly compliant cantilever arm, also capable of conducting electricity. The other end of the cantilever arm is attached to the top of a piezo-electric z-axis driver which will raise and lower the cantilever arm as the AFM tip is scanned across the surface of a sample. A piezo-electric X-Y scanstage controller may also be provided and connected to the bottom of the z-axis driver. The X-Y scanstage is preferably capable of scanning the movement of the entire system including the Z-axis driver, cantilever arm and AFM tip.

  • Patent number: 5657054
    Abstract: A stylus location system comprises a field emission device having an anode plate 32 and an emitter plate 2, and a plurality of piezoelectric point elements 34, 42 coupled to the anode plate. The piezoelectric point elements 34, 42 are capable of transforming electrical energy into ultrasonic energy and transforming ultrasonic energy into electrical energy. A stylus 30 is also coupled to the anode plate 32 and circuitry 36, 46, 48 is coupled to the piezoelectric point elements 42 for determining the position of the stylus 30. The circuitry 36 may also send a video data signal to the emitter plate 2 in response to the position determination.

  • Patent number: 5657053
    Abstract: A method for generating coordinate signals in conjunction with a surface of a field emission device having a cathode plate 2 coupled to an anode plate 32 comprises the steps of providing a first ultrasonic wave packet to the anode plate 32, receiving with a stylus 30 positioned proximate to the anode plate 32 the first ultrasonic wave packet, and then transmitting to the anode plate 32 with the stylus 30 a second ultrasonic wave packet responsive to the first ultrasonic wave packet. Next, receiving from the anode plate 32, with a plurality of piezoelectric point elements 44, the second ultrasonic wave packet, and then determining an x-position and y-position 35 of the stylus 30 responsive to the received second ultrasonic wave packet.
