Automatic software updating method

Abstract: An automatic software updating method in a communication network including a host computer, a plurality of branch processing computers each connected to the host computer for serving as servers, and a plurality of personal computers connected to a corresponding branch processing computer is provided. The method includes the steps of: (a) uploading a new software together with a version-up table including a version code to the host computer; (b) downloading the version-up table uploaded in step (a) to the branch processing computer; (c) determining whether to download the software using the version code of the version-up table downloaded in step (b); (d) downloading the software according to the result of step (c); and (e) installing the software downloaded in step (d) in the personal computer. Therefore, an out-of-date software of computer systems dispersedly arranged in the network can be automatically updated by a partially corrected or newly developed software.

Data processing network with upgrading of files

Abstract: A data processing network in which a plurality of workstations such as personal computers (PC) (12) are connected to a host processor (11) and contain PC programs at particular levels for controlling tasks on the personal computers. The personal computers send a signal to the host when they are about to conduct a task indicating which data files they have and at what level. The host has an object library containing a copy of each disk file for each version of PC program. The host determines if the personal computer has the latest level data file for the version of program at that personal computer and, if it does not, sends a copy of the latest level data file to the personal computer to replace the down-level data file. Preferably, the host checks if the personal computer has all the data files it needs for the particular task and, if it does not and if it should because of the version of PC program stored at the PC, the host can load a copy of the missing file to the personal computer. The host does not have to contain a record of all the levels of all the programs of all the personal computers connected to it. However, by updating the object library in the host, this arrangement ensures that all personal computers connected to it are automatically brought to the latest authorized level of data files as are required by the personal computer.

Multi-frequency multi-protocol wireless communication device

Abstract: A wireless communication device may take the form of a cellular telephone, of a portable personal communication device, or even of a desk top personal computer which is equipped to communicate over the wireless cellular communication system in effect in a particular area. The wireless communication device is configured to self-adapt to various operating frequencies and communication protocols which may be present in the cellular communication environment so that the device is able to provide communications in several service areas even though the frequencies of operation and the communication protocols in use in the service areas may be incompatible with one another. The wireless communication device may also include facilities for transmitting and receiving video, graphics, and data files over an RF bandwidth. The various communication standards and protocols which may be used for these communications are recognized by the communication device, and it self-adapts to provide communications in the formats, standards, and operating frequencies which are available in particular cellular communication environments.

Method for quickly booting a computer system

Abstract: A method for quickly booting a personal computer system using boot configuration information on memory and the attached devices that was created and saved in a hard disk at the preceding boot process. The method for a quick boot process includes the steps of performing a power-on self test POST) operation when a personal computer system is powered on or a reset button is pressed; performing a normal boot process after the POST operation; saving the contents of memory and the status of the attached devices to a hard disk; checking if a reboot is requested; restoring the saved boot configuration information from the hard disk, after POST is completed during the reboot process; checking whether or not an initial device configuration file and/or an automatic batch file were changed; and executing commands in the two files and saving a newly created boot configuration information to the hard disk for future boot. The personal computer system, may reboot quickly because of omission of execution of the initial device configuration filed and the automatic batch file.

Using Neural Networks for Credit Scoring

Abstract: Neural networks offer an alternative to numerical scoring schemes for credit granting and extension decisions. A standard back‐ propagation neural network running on a DOS personal computer is used with 125 credit applicants whose loan outcomes are known. Applicant characteristics are described as input neurons receiving values representing the individuals' demographic and credit information. Three categories of payment history, delinquent, charged‐off, and paid‐off, are used as the networks output neurons to depict the loan outcomes. After training on part of the data, correct classifications were made on 76–80% of the holdout sample.
