Abstract: Cache control protocols can be switched during running without changing an architecture for a segment descriptor or page descriptor for indicating an attribute of an area to be accessed. A plurality of processors each including a cache memory constitute a multiprocessor system which shares a main memory via a system bus. Each processor has module detecting means for detecting execution of a module which accesses a shared memory area on the main memory, by comparing the virtual space number and the instruction segment number concerning the accessing module with those numbers concerning the software modules preset which may access the shared memory area. Memory access executed in a module detected by the module detecting means is controlled in a cache control protocol of a store-through scheme which updates a main memory simultaneously with update of a cache memory. Memory access executed in other modules is controlled in a cache control protocol of a store-in scheme which does not update a main memory at update of a cache memory.

Abstract: A self-doping electrode to silicon is formed primarily from a metal (major component) which forms a eutectic with silicon. A p-type dopant (for a positive electrode) or an n-type dopant (for a negative electrode) is alloyed with the major component. The alloy of major component and dopant is applied to a silicon substrate. Once applied, the alloy and substrate are heated to a temperature above the major component-silicon eutectic temperature such that the major component liquefies more than a eutectic proportion of the silicon substrate. The temperature is then decreased towards the eutectic temperature permitting molten silicon to reform through liquid-phase epitaxy and while so doing incorporate dopant atoms into its regrown lattice. Once the temperature drops below the major component-silicon eutectic temperature the silicon, which has not already regrown into the lattice, forms a solid-phase alloy with the major component and the remaining unused dopant. This allow of major component, silicon and unused dopant is the final contact material.      Alternatively, a self doping electrode may be formed from an unalloyed metal applied to a silicon substrate. The metal and substrate are heated to a temperature above the metal-silicon eutectic temperature in an ambient gas into which a source of vaporized dopant atoms has been introduced. Dopant atoms in the ambient gas are absorbed by the molten mixture of metal-silicon to a much greater extent than they are absorbed by the solid silicon substrate surfaces. The temperature is then decreased to below the metal-silicon eutectic temperature. During this temperature decrease, the doped regrown silicon layer and the metal-silicon alloy final contact material are created in the same process as described above.

Abstract: The invention relates to vectors for cancer therapy which as a result of genetic differences between normal and transformed cells selectively eliminate the latter. This is made possible by integrating a sequence-specific recombinase into a viral or non-viral expression vector, whose expression is controlled by a transcription factor which has mutated in tumour cells and is therefore inactive, as well as by a suicide gene which is flanked by at least one recombinase-specific target sequence. Through the transcription-factor-mediated activation of the sequence-specific recombinase the vector is eliminated from untransforme d cells together with the suicide gene. The vector is, however, not eliminated from tumour cells in which the transcription factor is not active and expresses the suicide gene in said cells. After contact with a corresponding prodrug these cells are selectively killed off.

Title: Tintable luminescent paint
Inventor: VAN DUYNHOVEN DEBRA M
IPC: G09F13/20
Filed: 2000-06-01
Granted: 2003-08-19
Abstract: By combining alkali earth oxide aluminate phosphors with an alkyd base, a rheology improver, another pigment, an anti-skin additive, and other ingredients, one can achieve a luminescent paint that has characteristics including tintability, applicability, viscosity, appearance and coloration comparable to a non-luminescent paint, with adequate protection from moisture and at a relatively reasonable cost. An alkyd base formulation is the preferred formulation that will allow for the highest amount of loading without compromising the quality of the paint with respect to appearance or applicability. The appearance of the paint in daylight has minimal orange peel or pockmark affects because of the ability of this formulation to suspend and diffuse the large luminescent particles effectively while applying the product. In addition because of the effectiveness of this formulation the appearance of the glow is even, consistent and undisrupted in a properly installed scenario. This product is non-abrasive and will provide a smooth, even appearance.

Granted: 2004-11-02
Abstract: Periodically sending by a telecommunication controlled application an encrypted message to a licensed server to request permission to run and to obtain a list of permitted features. The license server application is executing on the same processor as the controlled application. Also resident on the same system is a license file which contains a list of applications that are permitted to run, the version number of the permitted applications and a list of permitted features. The license server is responsive to the encrypted message from the controlled application to read and decrypt the license file, read the serial number of the processor controlling the telecommunications system, compare the serial number obtained from the processor with the serial number stored in the license file. If there is a mis-match, no license is granted to the control applications and it will not be allowed to run. If the serial numbers match, then a comparison is made between the version number received from the application and the corresponding version number associated with the application in the license file. If the version number mis-matches, an encrypted message is sent to the application denying it permission to run. If the version number matches, an encrypted message is sent to the application granting it permission to run and listing the permitted features. To decrypt the license file, the license server utilizes a key that is assigned to the license server either globally or on a per system basis.

Abstract: In the present invention, the slave base station (64) attains synchronization with the reference base station (62) through messages (504) transmitted from and received by a mobile station (60) either in the soft handoff region between the reference base station (62) and the slave base station (64) or within a range which allows the mobile station (60) to communicate with the slave base station (64). When the mobile station (62) is not in communication with both the reference base station and the slave base station (62), then the round trip delay between the mobile station and the reference base station is measured by the reference base station (62). The reference base station (62) communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station (64) acquires the signal (504) from the mobile station (60) and determines when the signal from the mobile station arrives. The slave base station (64) then makes and estimates as to the length of the delay between transmission of a signal from the mobile station (60) to the slave base station (64). Based upon these measurements and estimates, the slave base station (64) determines the error which is present in the slave base station system time.
