Abstract: A method and apparatus performs a security analysis on a computer system to identify, notify, and possibly correct, vulnerabilities and discrepancies. The security system includes a number of security tools and utilities in order to perform these functions. The security system includes the capability to identify the system configuration and once this is done performs different processes to analyze the computer system directories, locate vulnerabilities in the files or directories, check the network access, do analysis of the users or groups which have access to the computer system and check the permissions which these parties have been granted, and analyze passwords of the users. The utilities include the functionality to permanently remove files from the computer system, mark particular files to be analyzed, as well as schedule the security tests to be performed at predetermined times.

Abstract: A method is disclosed for examining a body by transmitting the N continuous orthogonal signals, generated in accordance with the disclosed method, into the body and providing receivers for receiving and recording the N signals including reflections of the N continuous signals from one or more reflectors within the body. The travel-time to the reflectors for each of the N signals at each of the receivers is determined by cross correlating each of the N signals with each of the recorded signals at the receivers.

Abstract: The disclosure includes a computational system implemented with respect to a novel computational architecture for operating an externally-defined data based on client-defined rules. In one of the implementations, the architecture is utilized in a billing and customer service program. The architecture includes a engine unit which includes a number of processing modules which internally operate on generic data units that are independent of the particular application. a metadata engine receives externally-defined data and relates the externally-defined data and the relates the externally-defined data to the generic data units for use for the engine unit. a rules-based engine provides to the engine unit information related to the client defined rules. In this manner, the engine unit can be reused in a large part in a variety of different environments.

Abstract: Each of N continuous orthogonal signals are generated by summing a plurality of constituent sine waves together, where each of the sine waves has a known and mutually exclusive frequency and, the sine waves have a random or pseudo random phase where no two of the N signals includes a constituent sine wave of the same frequency. Each of the constituent sine waves has a prime number integer frequency. A body can be examined by transmitting the N continuous orthogonal signals into the body and providing one of the receivers for receiving the N signals including reflections of the N continuous signals from one or more reflectors within the body. The signals received at each of the receivers is recorded. The travel-time to the reflectors for each of the N signals at each of the receivers is determined by cross correlating each of the N signals with each of the recorded signals at the receivers. The travel-time can be used to derive an image of the body.
