Title: System and method for programmable illumination pattern generation
Inventor: SEUL MICHAEL
IPC: C12Q1/68
Filed: 2000-09-17
Granted: 2010-06-01
Abstract: A method and apparatus for the manipulation of colloidal particulates and biomolecules at the interface between an insulating electrode such as silicon oxide and an electrolyte solution. Light-controlled electrokinetic assembly of particles near surfaces relies on the combination of three functional elements: the AC electric field-induced assembly of planar aggregates; the patterning of the electrolyte/silicon oxide/silicon interface to exert spatial control over the assembly process; and the real-time control of the assembly process via external illumination. The present invention provides a set of fundamental operations enabling interactive control over the creation and placement of planar arrays of several types of particles and biomolecules and the manipulation of array shape and size. The present invention enables sample preparation and handling for diagnostic assays and biochemical analysis in array format, and the functional integration of these operations. In addition, the present invention provides a procedure for the creation of material surfaces with desired properties and for the fabrication of surface-mounted optical components. The invention is also for a system and method for progammable illumination pattern generation, including a novel method and apparatus to gennerate patterns of illumination and project them onto planar surfaces or onto planar interfaces such as the interface formed by an electrolyte-insulator-semiconductor (EIS), e.g., as described herein. This enables the creation of patterns or sequences of patterns using graphical design or drawing software on a personal computer and the projection of said patterns, or sequences of patterns ("time-varying patterns"), onto the interface using a liquid crystal display (LCD) panel and an optical design which images the LCD panel onto the surface of interest. The use of the LCD technology provides flexibility and control over spatial layout, temporal sequences and intensities ("gray scales") of illumination patterns. The latter capability permits the creation of patterns with abruptly changing light intensities or patterns with gradually changing intensity profiles.

Title: Aircraft spiralling mechanism - 2
Inventor: KUSIC TOM
IPC: B64C5/10
Filed: 2002-06-19
Granted: 2010-12-21
Abstract: An aircraft 1 in the form of an aeroplane with a spiral inducing assembly 2 which is capable of inducing the aeroplane to travel in a continuous spiralling motion without rolling. Two fins 3 and 4 are attached to a tube 5 that is able to rotate around the encircled part of the fuselage. The fins 3, 4 are able to rotate in a pivoting manner on the rotatable tube 5 with respect to the rotatable tube 5, thereby changing their pitch relative to the longitudinal axis of the rotatable tube 5. Fin 3 is larger than fin 4. The diferene in sizes between the fins makes the larger fin 3 exert a greater force on the rotatable tube 4 than the smaller fin 4 when the fins are pitched in unison. The aerodynamic imbalance between the fins thus casues the rotatable tube 5 to rotate. When pitched at an angle to the longitudinal axis in unison, both fins 3, 4 would exert a lateral force on the rotatable tube 5. Thus, as well as forcing the rotatable tube 5 to rotate, the fins 3, 4 would also push the rotatable tube sideways. But as the rotatable tube is pushed sideways, it rotates, and hence the lateral direction of push constantly revolves, causing a spiralling motion when in flight.

Abstract: A duplication/delivery center DDS records contents C11 and C12 on a recording medium M in accordance with requests from content providing apparatuses CP11 and CP12, duplicates the recording medium M, and delivers the recording medium M to users. When doing so, parts of the contents are encrypted. The content providing apparatuses CP11 and CP12 request a content control apparatus CC1 to control the contents on the recording media M. At the side of contents users, when a user sets a recording medium M in a video game console GM and tries to use a content that has been encrypted, the video game console GM requests, via a mobile packet communication network MPN, the content control apparatus CC1 to transmit a decryption key. The content control apparatus CC1 decides whether or not to transmit the decryption key based on the content of the request received from the content providing apparatus.
