Patent CA-2324759-A1 (CA)
Inventor: WILHELM GEORGE W JR
IPC: G06F21/12
Filed: 2000-10-30
Abstract: Tamper resistance is provided to avoid observation of the behavior of portions of software by calling a function exclusively available in one differentiated section of a processor and its peripherals and drivers from another differentiated section. A pseudo-random binary sequence generator is associated with each such differentiated section and incremented incident to the calling and performance of the function, respectively. The pseudo-random binary sequence values are compared prior to allowing or preventing further execution of the software.  The comparison can be performed at any privilege level and a variation of the invention provides additional security by utilizing an additional privileged function to perform the comparison. An enhancement of the invention corrupts data or program files using a PRBS value at one privilege level and performs the inverse function to restore the data or program files at another privilege level with its own PRBS value.

The door assembly allows the tightness of the door to be easily adjusted without the need for shims, and allows the tightness to be adjusted even when the dryer is in operation.
Patent CA-2325531-A1 (CA)
Inventor: MOSCATO ANTHONY
IPC: G06T7/00
Filed: 2000-02-08
Abstract: A method and system for verifying the intended imaging produced by a printer allow this task to be accomplished in essentially real-time, and utilizing relatively inexpensive, and high speed (e.g. about 200 feet per minute or greater) components. A computer control commands a raster image processor (RIP) to generate electronic print data (e.g. a bitmap) that is sent to an electronic digital printer (such as an inkjet cartridge array) and also to a print monitor. The printer images the bitmap onto a web or sheet, then a linear digital photosensor (e.g. photodiode) array scans essentially every pixel across the width of the web or sheet image area and transmits the scanned data to the print monitor system, which compares it to the bitmap produced by the RIP. If there is some discrepancy (of any sort), a message is generated which is ultimately transmitted back to the computer control where it may be used to log bad business forms being produced, generate human recognizable indicia (such as a warning light or sound), or shut down the system components. A second linear photodiode array may be provided before the printer and the data from it sent to the print monitor system to be combined with the electronic bitmap and compared to the data from the first sensor to determine whether there is any deficiency.

Patent CA-2332387-A1 (CA)
Inventor: BLAHUT DONALD EDGAR
IPC: H04B10/272
Filed: 2001-01-09
Abstract: In a power splitting passive optical network (PSPON) (101) which provides fiber-to-the-home (FTTH), time division multiplexing/time division multiple access (TDM/TDMA) communication is employed for downstream/upstream transmission over a fiber. A framed structure is used for the downstream transmission of ATM cells from an optical line card (OLC) (401) to a (104) in the outside plant and thence to a plurality of optical network units (ONUs) (106) which are each associated with a home or business. The ONU at each home/business is connected to end user terminal equipment such as one or more PCs (109), televisions (111), and telephones (107). The ATM cells transmitted within each fixed length frame may be addressed to a specific ONU for a particular end user terminal, or they may be broadcast to many or all ONUs. An ATM cell may also carry a control channel or messages directed to the ONUs. A framed structure is also employed for upstream burst transmission from the plural ONUs to the OLC. Specifically, in the upstream direction each ONU transmits one burst per frame that includes a header and a payload containing a variable number of bytes. The length of each payload in a burst transmitted upstream by an ONU is determined as a function of the bandwidth requirements of the end user terminal equipment connected to that ONU as well as the bandwidth requirements of the end user terminal equipment at the other ONUs. When the bandwidth requirements at an ONU changes, that information is communicated upstream to the OLC where an upstream bandwidth message is created and transmitted downstream to the ONUs. That upstream bandwidth management message modifies the length of the payload in the burst in a subsequent frame transmitted by that ONU whose bandwidth requirements have changed, and also changes the locations within the frame that the other ONUs transmit their bursts if they transmit in the frame after that payload-length modified ONU.

IPC: A23L7/10
Filed: 2001-04-26
Abstract: A method is described for obtaining dextrin-enriched and beta-glucan-enriched fractions from barley flour. In particular, barley flour is mixed or ground in about 60%  ethanol at boiling temperature, then dextrinized by addition of thermostable alpha-amylase into the aqueous ethanol and relaxing at boiling temperature. The dextrinized mixture is filtered such that beta-glucan is retained on the filter and dextrin is in the filtrate. To increase the purity of the beta-glucan to at least > 45% db and to increase the dextrin yield, the beta-glucan residue is resuspended in 60% ethanol and treated a second time with alpha amylase and filtered as previously noted. After alcohol is evaporated from the combined filtrates, the dextrin is spray dried into a powder.

Title: Laser-guided manipulation of non-atomic particles
Inventor: ODDE DAVID J
IPC: B01J19/12
Filed: 1999-09-30
Abstract: A method and device for using laser light to trap non-atomic size particles optically within a hollow region of a hollow core optical fiber are disclose d. Also described are a method and device for flexibly transporting the trapped  particles along the fiber over long distances. The present invention allows to manipulate and guide particles made of a wide variety of materials, includin g biological tissue and aerosols, along the optical fibers and deposit the materials on various substrates. The laser guiding device (44) comprises a laser beam a laser beam source generating a laser beam (46), which is direct ed to an entrance (56) of a hollow core optical fiber (50) by a focusing lens (64). A source of the particles to be guided through the fiber provides a certain number of particles near the entrance to the fiber. The particles ar e then drawn into the hollow core (48) of the fiber by the focused laser beam,  propagating along a grazing incidence path inside the fiber. Laser induced optical forces generated by scattering, absorption and refraction of the las er light by a particle traps the particle close to the center of the fiber and propels it along. Any micro-size material, including solid dielectric, semiconductor and solid particles as well as liquid solvent droplets, can be  trapped in the laser beams and transported along optical fibers due to the n et effect of exertion of these optical forces. After traveling through the leng th of the fiber, the particles can be either deposited on a desired substrate o r into an analytical chamber, or dealt with depending on the goal of a particular application.
