Title: System for automatically routing calls to call center agents in an agent surplus condition based on service levels
Inventor: REIMAN MARTIN I
IPC: H04M3/523
Filed: 2000-11-23
Granted: 2004-05-25
Abstract: The system for automatically routing calls to call center agents in an agent surplus condition provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.

Abstract: A method of dynamic channel allocation in a frequency hopping communications system is disclosed providing improved efficiency and reliability. During the course of communications between a plurality of transceivers over a frequency hopping wireless communications link, a transceiver begins evaluating the performance of each channel in the hop sequence, starting at a fixed point in the sequence. The transceiver proceeds sequentially through the hop sequence, until a channel fails to satisfy a predetermined quality criterion. A channel which fails to satisfy the quality criterion is considered bad, and substituted with a replacement channel from a set of available channels via an unacknowledged channel replacement command. The channel evaluation process is subsequently reinitiated beginning anew at the fixed point in the hop sequence, thus operating to maintain a set of consecutive good channels.

Title: System and method for acquiring an optical target
Inventor: SHAH GOVIND
IPC: G01S17/89
Filed: 1992-07-07
Granted: 2002-09-17
Abstract: An optical target is acquired by an optical scanning system according to an in-band target frequency in an input signal from an optical scanning device. Both the in-band energy level and the out-of-band energy level of the input signal from the optical scanning device are determined. These two energy levels are compared and a possible detection of the target is determined according to this comparison. A minimum threshold of in-band energy is required in order for the possible detection to be confirmed. The input signal may have various frequencies due to various amounts of magnification of the acquisition target as scanned by the optical scanning device. Thus the input signal may represent the target as various frequencies due to the various amounts of magnification. The various amounts of magnification of the acquisition target are due to various scanning distances between the scanning device and the acquisition target. Magnification compensation is therefore performed by providing an amount of frequency shifting of either the center frequency of a filter or the input signal frequency. The amount of frequency shifting is determined according to scanning distance. The frequency shifting is accomplished by performing digital-to-analog conversion on the digital input signal at a fixed frequency.  The output of the digital-to-analog converter is applied to an analog-to-digital converter where the analog signal is resampled at a varying resampling frequency. When the resampling frequency differs from the sampling frequency the signal is frequency shifted.  Alternately, the resampled signal may be buffered and clocked out, in which case the frequency of the input signal is effectively shifted. In order to vary the amount of frequency shift according to the scanning distance, the resampling frequency applied to the analog-to-digital converter is varied according to the scanning distance. The relationship between the various resampling frequency and the varying scanning distances may be selected to cause the various input frequencies representative of a scanned acquisition target to be shifted to a single predetermined fundamental frequency.

Abstract: A process for manufacturing an active substance-containing product from strip tape. A broad web material roll is mounted, loosely rotatable, on a take-up mandrel. The web of material is drawn, in its entire width and without tensile stress, from the roll of material by a vacuum roll, and is separated into individual strips in the negative pressure zone of the vacuum roll by rolling a multiple circular knife roll. At the end of the negative pressure zone of the vacuum roll, each strip is drawn from the vacuum roll and is introduced in a take-up channel and continuously conveyed by negative pressure. Each strip is turned on its way to or through the channel by about 90°. At the end of the channels the strips are led at least two at a time, and conveyed further in a groove for further processing to form the finished product.
