Abstract: The present invention provides a power frequency, i.e., time-varying, magnetic field (PF-NF) detector system for characterizing the operational condition of a remote facility responsive to time-varying magnetic fields generated by electrical transmission lines associated with the remote facility. The PF-MF detector system advantageously includes a PF-MF sensor which generates N time-varying magnetic field data sets, and a PF-MF analyzer which generates an operational condition assessment responsive to the N time-varying magnetic field data sets, wherein N is an integer greater than or equal to 1. Additionally, the PF-MF detector system includes an accumulator which stores and forwards the N time-varying magnetic field data sets to the PF-MF analyzer via a communications channel. A method for characterizing the operational condition of inaccessible electrical equipment responsive to the time-varying magnetic field generated by a transmission line are also described.

Abstract: A portable system for sampling the ambient air of a selected environment for the presence of unwanted chemical warfare vapors, such as nerve or blister gases, is disclosed. The excitation for the electrical elements of the system can be originated from a battery or from an ac excitation. The system comprises a detector unit having first and second ion mobility spectrometers which simultaneously detect and monitor for the presence of the chemical agent vapors so as to provide an accurate and quick determination of the unwanted chemical vapor within the selected environment, without false alarming to non-chemical warfare agent vapors, which act as interferents. The system design also allows monitoring in the presence of electromagnetic interference (EMI).

Abstract: An attachment integrated claims (AIC) system includes an e-mail form (with specific fields that must be filled out) that adjusts itself, in both information required and formatting, to meet the demands of the receiving party. It is particularly advantageous for Electronic Data Interchange (EDI) situations where a user must send similar (but not necessarily identical) messages to several organizations. This is particularly important where, once an e-mail is received by those organizations, the information in the message must be digitally integrated into differing legacy information systems. In other words, the AIC system permits transmission of a dynamic claim form and integrated attachment to an insurance carrier via a non-clearinghouse communications channel. An AIC system including several computers connected via a communications channel, an electronic file, and an operating method therefor are also described.

A memory which stores a seamless spherical image data set formed from N circular image data sets captured by a single lens, where the circular image data sets are taken from a single focal point of the lens, and where N is a positive integer greater than 1 is also described.

Abstract: The forming time necessary to superplastically form an object from a metal sheet is estimated by empirical analysis. The required rate of gas mass flow into a forming cavity is then determined using either a nomograph composed of four interrelated graphs, or a single graph which requires the input of fewer variables than the nomograph. The present invention may also be used to form cells of multiple sheet panels from a stack of sheets. In the latter application, forming time necessary to complete forming of the cells from an interim point where the core sheet forming pressure and the die temperature are increased from interim levels to their final values is estimated by empirical analysis. A nomograph or single graph of the present invention then determines the gas mass flow rate necessary to safely and efficiently complete forming of the cells from the foregoing interim point.

Abstract: A fiber optic connector and an associated fabrication method where the connector has a connector housing having a base side, a and pair of sidewalls upstanding from the base side that are spaced apart in relation to each other, and each of the housing sidewalls define at least one aperture through which optical signals can be transmitted into and out of the housing by an input optical fiber and an output optical fiber, respectively, located in fixed positions outside the housing, and a pair of optical lens elements are contained within the housing which collimate optical signals transmitted via the respective optical fibers. The lens elements are precisely aligned with respective optical fibers within submicron tolerances using internally-housed micro-aligners. As a result, the fiber optic connector of the present invention can provide efficient coupling between optical fibers, such as optical fibers in two spliced composite parts.
