Title: Upgrade method for software
Inventor: KIM HO KWANG
IPC: G06F13/00
Filed: 1998-12-01
Abstract: PURPOSE: An upgrade method for software is provided to prevent illegal duplication and installation of the software by creating a blacklist of licensed products' serial numbers and blocking the upgrade of those products with the serial number listed in the blacklist. CONSTITUTION: An upgrade method for software is composed of reception, verification, confirmation, and installation. User receives patch file through PC connection and runs patch file's installation file. The patch file checks for bugged program and revision programs' versions, and confirms that the revision program's version is higher than the bugged program's version. If revision program's version is lower, installation is halted and alert message is output to the user. If version is higher, program verifies the serial number by displaying a message that reads "input serial number" or automatically detecting the serial number by the program. If serial number confirms the product's authenticity, the serial number is again verified to determine it's not listed on the blacklist. If the serial number is listed on the blacklist, installation process is halted and a message that reads "serial number has been distributed or there has been a program error. Please contact the program vendor" is displayed. If the product is authentic and free from serial number distribution, the program executes delete, addition, and change processes to upgrade itself.

The bracket has a plurality of perimeter members that corresponds to the outer edge configuration of the object. The perimeter members include an inwardly extending flange which supports the perimeter edge of the object. The bracket perimeter can be closed or open and can have cross reinforcing members, if desired. The cross-section of the perimeter members making up the bracket can include a curved convex outer surface extending upwardly and outwardly from the flange to a flat surface perpendicular to the flange. The perimeter member forms one half of a grout line mold formed in between adjacent objects embedded in the finished wall. The interior of the perimeter member can be hollow to allow flexure between the outer flat surface and the inner flange supporting the object. The object is secured to the bracket along the flange area by means of a suitable releasable adhesive or by mechanical retainers, such as a detente or an elastomeric band which holds the object in the bracket. The bracket can be formed from permanent materials for long term usage or from inexpensive frangible materials which can be broken and removed from the wall and form after a single use.

Abstract: The invention is directed to a liquid crystalline display comprising a display cell containing liquid crystalline material and a retardation layer. The retardation layer comprises a, preferably slightly cross-linked, high-molecular weight material layer and a substrate, wherein the high-molecular weight material has a nematic phase above its Tg and a dynamic viscosity at the working temperature of at least 100 Pa.s. The difference of the Tc of the high-molecular weight material and the Tc of the low-molecular weight material of the display cell (TCcell) is in the range of -30 DEG  C. to +30 DEG  C., preferably in the range of -20 DEG  C. to +20 DEG  C., and more preferably in the range of -10 DEG  C. to +10 DEG  C.; and the Tg of the high-molecular weight liquid crystalline material is lower than 50 DEG  C. It was found that if high-molecular weight material is used with a Tc comparable with that of the, preferably low-molecular weight, liquid crystalline material of the active cell, the temperature dependency of the retardation value of the retardation layer is comparable with that of the active cell. Thus, the retardation value of the retardation layer is comparable with that of the active cell within the temperature range in which displays are used. It was further found that by cross-linking of the high molecular weight liquid crystalline material, the retardation layers according to the invention become less susceptible to pinhole forming and unwanted variation of the twist, and have improved mechanical stability.

Abstract: PURPOSE: A method is provided to achieve a high speed communication by allowing a home location register(HLR) function to be performed in an ATM-based IMT-2000 network system. CONSTITUTION: A connection to HLR is made through an ATM device driver, and a data transmission path between ATM mobile communication switching center and HLR is formed. The ATM message transmitted through the ATM card is converted into an HLR message which is then converted into an ATM message having DLPI primitive format. The ATM message is then transmitted to an ATM device driver. The method is applicable to an ATM-based SCP/IP system.
