Abstract: A data management system for storing data in a multiple-level cache arrangement of a database comprises a multi-tier cache memory for initially storing all data in summary form in a secondary cache which may be the database; a processor for receiving requests for data and for moving requested data from the secondary cache to a primary cache, wherein, when subsequent requests for data are received, the primary cache is searched before the secondary cache; and for periodically synchronizing and merging all data in the primary cache back into said secondary cache to refresh said primary cache and remove stale information. The system is particularly useful for managing a telecommunications system call detail summary database in which telephone call details are collected as AMA records after the calls terminate and the AMA records are forwarded to a call detail database for storage in summary form and analysis by an external system, for example, for fraud analysis or billing purposes.

Abstract: The present invention relates to chromotropic nitrone spin trapping agents, methods of making these agents, compositions comprising same, and methods of their use. In particular, azulenyl nitrones of the present invention are effective agents for trapping free radical species and find use as efficient antioxidants in physicochemical and biological systems. Accordingly, the invention also relates to spin adducts formed from the combination of azulenyl nitrones with free radicals. The compounds of the present invention are readily prepared from available starting materials and find further use in assays and in a number of diagnostic, prophylactic and therapeutic applications, including but not limited to the alleviation, modulation and inhibition of the negative effects of carbon-centered or oxygen-centered radical species and other products of oxidation. Moreover, the combination adducts may be colorimetrically detected and, optionally, isolated and characterized to obtain valuable information (e.g.

Abstract: Method and apparatus for providing visualization of information contained in a data set is provided. The data set is arranged in first and second categories of data, and a selection variable and a summary variable are chosen from the second category of data. A unique value is located in the first category of data which matches each selection variable, and a statistical summary of the summary variables is computed for each located unique value in the first category of data. The resultant display is based on the computation of the statistical summary.

Abstract: The remote controlled security device which can be controlled by a radiant energy transmitter so as to lock or unlock it, is mounted on the inside wall of a container and has a locking bar which is engageable with a locking plate that has an aligned opening for receiving locking bar of the security device. The locking bar can be moved by stepper motor from the locked to the unlocked position in response to actuation of the remote control transmitter to allow the door of the container to be locked or unlocked. There is also provided a key with an opening which can be inserted through the wall of the container to engage a projection which has the same shape as the opening in the key to allow the lock to be manually locked or unlocked.

Abstract: An improved locking device which has a body member with a cable which has one end attached to the body member and a second end of the cable which can be inserted into the body member in a first direction but which cannot be withdrawn in a second direction. An improved spiral spring biases a disc that rides on a ramp into engagement with the second end of the cable so as to lock it so it cannot be withdrawn from the body member, the coil spring provides a simple and efficient biasing device.
