Abstract: A method for operating a TEM cell to determine the characteristics of a radiation source in a circuit. The circuit is placed in the TEM cell such that the relative orientation of the circuit and the TEM cell is measurable. The TEM cell provides an output signal indicative of the energy radiated by the circuit when the circuit is operated in the TEM cell. The output signal of the TEM cell is measured for at least 6 different relative orientations of the circuit and the TEM cell. The electric and magnetic dipole moments of a radiation source having an orientation and physical dimension associated therewith are determined from the measured output signals. The electric and magnetic dipole moments determined from the measured output values are compared to moments predicted by each of a plurality of antenna types to provide an estimate of the orientation of the radiation source relative to the circuit.

Abstract: A system and method is provided for scheduling data collection sessions between a collection computer and one or more computerized branch exchanges (CBXs). Telephone statistics data collected from the CBXs is stored into a database in the collection computer and accumulated according to fixed time intervals and one or more previously created organizational hierarchies. A report generation system and method is also provided for selectively retrieving stored data and formatting it into a report with features including time zone adjustment, time offsets, data element calculations, and "where" conditions, all in a manner which does not require the user to understand the underlying database organization or any programming languages.

Abstract: A system and method for assessing the electric and magnetic field generated by equipment under test (EUT) by maintaining the EUT in a specified, fixed tilt position, allowing the EUT to rotate while in that specified position and tilting the TEM cell through at least two angles about the EUT. Embodiments contemplate that a fixed tilt mechanism for maintaining the EUT in a fixed position relative to the tilting of the TEM cell is used. The present invention further contemplates various schemes for determining the electric and magnetic fields generated from the EUT based upon the composite electromagnetic reading from the TEM cell. These schemes, which result in improved measurements of the magnetic and electric fields, determine the angles to which the TEM is tilted.

Abstract: Automatic parametric testing of a system can be achieved by varying a parameter such as speed, voltage, and/or temperature, and then monitoring system performance. Such testing can be used to determine whether a given system meets specifications and performance variations from system to system.

Abstract: A light transmission device includes a multiplicity of lightpipes of differing lengths wherein light output from each of the lightpipes has substantially a same intensity when light applied to an input end of each of the lightpipes has substantially another same intensity. In accordance with a preferred embodiment of the present invention, an area of a surface of the input end of each of the lightpipes is textured and the size of the area which is textured is varies from lightpipe to lightpipe. A method in accordance with the invention transmits light through lightpipes of different lengths. The light transmittivity of each of the lightpipes is regulated so that the light output from each of the lightpipes has substantially the same intensity.

Abstract: A method and system in which lip synchronization is restricted to a single system in a multiple system communication of video data and audio data. In the preferred embodiment, the receiving system synchronizes video and audio signals for presentation. The originating system forms and processes video and audio signals separately. For many systems, the processing involves dissimilar delays. Consequently, when the information is transmitted through a network to the receiving system, the video and audio data is nonsynchronous. The originating system provides delay information that is indicative of the dissimilarity of video and audio processing time at the originating system. The delay information is utilized at the receiving system to determine an adaptive compensation delay for introduction at the appropriate video or audio processing path. By providing a single compensation delay for multi-system communications, the total delay is potentially reduced.

Abstract: An embodiment of the present invention is a method for dynamically routing incoming calls through a private branch exchange (PBX) in response to commands issued by a host computer and, in particular, for routing incoming calls after routing information has been obtained from conventional ACD call handling techniques. In particular, an embodiment of the present invention is a method for dynamically routing incoming calls through a private branch exchange (PBX), which method comprises the steps of: (a) receiving an incoming call; (b) requesting a route request from a call processing module of the PBX, the route request being referred to as an internal route request; (c) receiving a route request for the incoming call from an alternate source, the route request being referred to as an external route request; and (d) rejecting the internal or the external route request on the basis of a priority scheme.

Abstract: A method for generating test data for testing a memory having k data bits and n address bits, where n is less than or equal to 2 times k. For each address location for which test data is desired, the address bits for the location are combined to form the test data for the location. First, two mutually-exclusive groups of n minus k non-repeating bits of the address word are selected. Second, the two groups of address bits are combined using an exclusive-OR operation. Third, the results of the exclusive-OR operation are combined with any remaining bits of the address word to form the test data for the address location. For example, in one embodiment, the most significant n minus k bits of the least significant k bits of the address word are combined, via an exclusive-OR operation, with the most significant n minus k bits of the address word. The resulting data is then concatenated with the remaining bits of the address word.

Abstract: System and method for outdialing telephone calls on a basis which takes into account the availability of agents who are assigned to process telephone calls placed. In accordance with the invention, telephone calls are placed ahead of the availability of agents so that the overall productivity of the agents is increased. The number of telephone calls that should be placed is determined in light of the actual measurements of system performance and in light of performance objectives. The determinations are dynamically refined based on measurements of actual agent and telephone call activity provided by the telephone system.

Abstract: Method and apparatus for determining the telephony features assigned to a telephone connected to a central switch. By communicating with the central switch, the telephone generates a list of assigned telephony features. The list of telephony features is stored in a nonvolatile memory and displayed to the telephone user.
