摘要： An identification system using biometric information of human body parts and a secret sequence code. In particular, biometric information of human body parts is used to form the secret sequence code. Specifically, a combination entry device recognizes user's fingerprints which are entered as a sequence. The fingerprints must be entered in the proper sequence in order to be recognized by the system. The fingerprints are preferably recognized using a fast technique with a low-probability level of rejection. While the sensor can be fooled for any one fingerprint. The use of a plurality of different fingerprints improves the identification capability. In particular, the combination of fingerprints in the proper order is necessary to undo the lock.

摘要： A method and a system to re-align onto a detector array a holographic image of a Fourier region hologram stored in a medium, with the medium spinning around a first axis, and the hologram being generated by a reference beam and a signal beam. In generating the hologram, the reference beam is incident on the medium with respect to a second axis at a second-axis-incident angle, and a third axis at a third-axis-incident angle, such that the holographic image of the hologram when reproduced by the reference beam is aligned onto the detector array. Also, the three axes are substantially orthogonal to each other. As the medium spins, the medium's orientation can change through tilting with respect to the second and the third axes so that the holographic image when reproduced by the reference beam is not aligned onto the detector array. In one embodiment, the holographic image is re-aligned onto the detector array by tilting the reference beam such that when re-aligned, the incident angle of the reference beam on the medium with respect to the second axis is intentionally tilted to be different from the second-axis-incident angle, and with respect to the third axis to be different from the third-axis-incident angle.

摘要： A light conductive controlled shape droplet display device of the invention includes a light source. A light conductive substrate receives and conducts light from the light source. A cover disposed relative to the substrate, conducts light received from the substrate out and away from the display device. Pixels in the display are defined by fluid droplets in optical communication with the substrate and the cover. Hydrophobic layers associated with the substrate and the cover control the shape of the fluid droplet in conjunction with properties of the fluid droplet. Persistent displays are possible, as are displays that require periodic refresh to maintain the display. Electrodes modulate the amount of light conducted by the fluid droplets from the substrate into the cover. In preferred embodiments, each pixel includes sub-pixels formed by different primary colored fluid droplets.

摘要： A peristrophic multiplexing system directs a signal light beam and reference light beam onto a selected recording spot in the recording medium. The light beams collectively define a plane of interaction. Either the recording medium or the signal/reference beam are rotated relative to the other through a succession of peristrophic multiplexing angles. Those angles cause relative rotation about an axis that is not perpendicular to the plane of selectivity. The rotation occurs contemporaneously with the modulating of the hologram on the medium.
