Title: Anti-counterfeit authentication method for optical memory cards and hybrid smart cards
Inventor: DREXLER JEROME
IPC: G07F7/08
Filed: 2001-02-08
Abstract: The invention is a method and system for inhibiting the use of counterfeited optical memory cards (11) and hybrid smart cards that use Drexon.TM. reflective laser recordable media (17) for recording and storing data. Use of such counterfeit version of Drexon.TM. optical memory cards (11) can be inhibited by use of two or more LEDs, or semiconductor lasers, which would focus their light beams on the apparent Drexon.TM. optical memory stripe (17). Using photodetectors, the reflectivity of the Drexon.TM. stripe (17) would be measured at two or more wavelengths including the visible and the infrared so as to identify the Drexon.TM. media (17), a silver particle-based material which has a unique reflectivity vs. wavelength characteristic. If the relative reflectivities match those predetermined characteristics of the Drexon.TM.  media (17), the card (11) would not be rejected; otherwise it would be rejected.

Abstract: An interface for controlling the transmission of data between integrated circuit (IC) chips. The interface comprises a data bus for transmitting data from a first integrated circuit chip to a second integrated circuit chip, and a control bus for transmitting control signals between the first and second integrated circuits. The first IC has a memory for receiving data for transmission to the second IC, and the second IC has a scheduler and a data output port, the scheduler being arranged to control the transfer of data from the memory of the first IC to the data output port of the second IC via the data bus. The interface is capable of stopping and reinitiating data transmission on detection of errors in transmitted data, and the interface may include a code transfer bus for transferring error detection code separately from associated data.

Title: Folding multipurpose pocket tool with floating springs
Inventor: RIVERA BENJAMIN C
IPC: B25B7/22
Filed: 2002-12-18
Abstract: A folding multipurpose hand tool including folding pliers or scissors and other tool blades and bits. A pair of handles each has a pivot axle at each end. A base of each pliers jaw or scissors blade is mounted on the pivot axle at one end of a handle, allowing the handles to fold around the jaws to blades to a compact folded configuration of the tool. Each handle has frame side members with attached flanges.      Elongate springs lie between the handle frame side members and fit around the flanges, rather than being riveted to the handle frame side members. The springs press against the base of each pliers jaw or other tool blade, to keep each in a folded position or support it in a deployed position. One end of a spring may be hooked around a spring retainer at one end of the handle. The pivot axles interconnect the handle frame side members and the jaws, blades, or tool bits.

Title: Method and device for identifying a biological sample
Inventor: YIP PING
IPC: G06F19/00
Filed: 2001-09-18
Abstract: Methods, apparatus and systems for identifying a biological sample that generate a data set indicative of the composition of the biological sample are provided. In a particular example, the data set is DNA spectrometry data received from a mass spectrometer. The data set is denoised, and a baseline is deleted. Since possible compositions of the biological sample may be known, expected peak areas may be determined. Using the expected peak areas, a residual baseline is generated to further correct the data set. Probable peaks are then identifiable in the corrected data set, which are used to identify the composition of the biological sample. In a disclosed example, statistical methods are employed to determine the probability that a probable peak is an actual peak, not an actual peak, or that the data are too inconclusive to call.

Abstract: A device for delivering medicaments to oral structures contains a flexible backing having a plurality of microstructures protruding from one surface of the backing, and a binder layer containing medicaments disposed on the backing and/or microstructures. Because the device contains microstructures that form obstacles or barrier that minimize the flow of medicaments away from the target oral structure, the medicaments stay at the desired longer thereby being more effective at treating the oral structure. One particularly useful application of the inventive device is for whitening teeth.

Title: User configurable demand deposit account system and method
Inventor: CASE GLEN M
IPC: G06Q20/00
Filed: 2001-11-29
Abstract: A computer-implemented or manual process is disclosed for a user to configure important features of a demand deposit account, as at a financial institution such as a bank, for features and periodic cost using options for each feature as set by the institution. Interest paid, balance levels, teller and ATM uses, direct deposit, canceled check return, and other features have two to fifteen or more options which can be selected among. The user, working directly at a computer terminal or through an agent using a terminal or printed materials displaying the features and options, selects a desired option for each feature of the account from among those offered, depending on the user's needs and habits. When an option is selected and submitted for all the features, the system computes the monthly cost of account from a database or look-up table and displays that cost, the options selected for each of the features, and whether alternatives are available for lowering the cost or increasing the services. The user can accept the account or can explore any alternatives shown. Alternative options are displayed for reducing the cost of the account and for increasing the services in the account, and, on each iteration, the new cost, options, and further alternatives are shown. When the account configuration is accepted, then the user's identification is taken and the account is set up. The account may, however, be subject to credit approvals and/or signing of account agreements.

IPC: E21B43/02
Filed: 1997-10-02
Abstract: The present invention provides a method of treating a wellbore penetrating a subterranean formation with a treatment fluid whereby fine particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate coated with a tackifying compound, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of any fine particulate within the formation upon flow of fluids from the subterranean formation through the wellbore. Alternatively, the tackifying compound may be introduced into a subterranean formation in a diluent containing solution to deposit upon previously introduced particulates to retard movement of such particulates and any fines subject to flow with production of fluids from the subterranean formation.
