Inventor: TREZZA THOMAS A
IPC: A23B7/16
Filed: 1998-08-10
Abstract: L'invention concerne des procédés de conservation de fruits frais au moyen de conservateurs pour fruits frais qui prolongent la durée de conservation des fruits frais, en particulier des fruits coupés frais. Le conservateur pour fruits frais préserve la texture, le goût, l'apparence, le croquant et la couleur du fruit frais, en particulier de la peau exposée du fruit frais. Ce procédé comporte les opérations consistant: à prendre une solution de conservateur pour fruits renfermant de l'eau, des ions calcium et des ions ascorbate, dans laquelle l'ion calcium et les ions ascorbate se trouvent dans un rapport ionique compris, de préférence, entre environ 1,5:1 et environ 2,5:1; ainsi qu'à appliquer ledit conservateur pour fruits sur le fruit. De préférence, le fruit est ensuite conservé à une température qui ne congèle pas le fruit; on a constaté que des températures de -6  DEG C ne congèlent pas les pommes. De préférence, le fruit est conservé à des températures comprises entre environ -7  DEG C et la température ambiante, d'environ 20  DEG C, plutôt entre environ -2  DEG C et environ 7  DEG C, idéalement entre environ 2  DEG C et environ 5 DEG  C.

Title: Apparatus and process for verifying honest gaming transactions over a communications network
Inventor: CAMPBELL CHERYL SUSAN
IPC: G06Q40/04
Filed: 1998-09-01
Abstract: Apparatus and method for verifying honest gaming transactions over a communications network includes structure and process whereby a host processor receives a random number from a satellite processor over the communications network. The host processor generates a game seed based on the random number. The host processor also receives an arbitrary game input from the satellite processor and generates a game result based on the game input, the game seed, and predetermined game rules. The satellite processor provides the random number and the arbitrary game input to the host processor over the communications network, and receives data corresponding to the game seed and the game result from the host processor. The satellite processor verifies the honesty of the transaction by (i) generating a game result based on the game input, the data corresponding to the game seed, and the predetermined game rules, and (ii) compares the generated game result with the received game result. A storage medium is also provided for storing a computer-implemented program to carry out the functions described above.

Patent CA-2313296-A1 (CA)
Title: Method and apparatus for improving synchronization in a document inserting system
Inventor: ANTONELLI NICHOLAS R
IPC: B43M3/04
Filed: 2000-06-30
Abstract: A method and apparatus for improving the timing between the releasing of documents from enclosure feeders and the arrival of pusher fingers fixedly attached to a conveyer belt in a gathering section of an inserting machine. As the conveyer belt begins to wear and stretch after being used for a long period of time, the timing between the releasing of documents and the arrival of pusher fingers may no longer be appropriate. By using two sensors placed, preferably, at the two ends of the gathering section to measure the timing of the arrival of the pusher fingers at the sensors, the stretch of the chain can be determined and the delay of the arrival of a pusher finger at each enclosure feeder can be calculated.  Adjustment to the releasing timing at each enclosure feeder can be made accordingly.

Title: In-plane mems thermal actuator and associated fabrication methods
Inventor: COWEN ALLEN
IPC: F15C5/00
Filed: 2000-09-01
Abstract: A MEMS thermal actuator device is provided that is capable of providing linear displacement in a plane generally parallel to the surface of a substrate.  Additionally, the MEMS thermal actuator of the present invention may provide for a self contained heating mechanism that allows for the thermal actuator to be actuated using lower power consumption and lower operating temperatures. The MEMS thermal actuator includes a microelectronic substrate having a first surface and at least one anchor structure affixed to the first surface. A composite beam extends from the anchor(s) and overlies the first surface of the substrate. The composite beam is adapted for thermal actuation, such that it will controllably deflect along a predetermined path that extends substantially parallel to the first surface of the microelectronic substrate. In one embodiment the composite beam comprises two or layers having materials that have correspondingly different thermal coefficients of expansion. As such, the layers will respond differently when thermal energy is supplied to the composite. An electrically conductive path may extend throughout the composite beam to effectuate thermal actuation. In one embodiment of the invention a two layer composite beam comprises a first layer of a semiconductor material and a second layer of a metallic material. The semiconductor material may be selectively doped during fabrication so as to create a self contained heating mechanism within the composite beam. The invention also comprises a MEMS thermal actuator that includes two or more composite beams. The two or more composite beams may be disposed in an array or a ganged fashion, such that the multiple composite beams benefit from overall force multiplication and are therefore capable of greater and more linear displacement distances. The invention is also embodied in a method for fabricating the MEMS thermal actuators of the present invention.
