Title: Estimation of a work item's wait-time from the present stages of processing of preceding work items
Inventor: FLOCKHART ANDREW D
IPC: H04M3/523
Filed: 2000-06-05
Abstract: To improve the prediction of wait times of calls waiting to be processed, or to improve the prediction of completion times of calls that are presently being processed, in low-volume call centers or splits/skills, additional data points are created - either manually or automatically - during the processing of each call that is presently being processed, for use in effecting wait-time estimates of the waiting calls. At each of the plurality of points in the processing of each of the plurality of calls, information about the call that is relevant to how long completion of the processing of the call is likely to take is obtained. This information is applied to historical information about previously-processed calls to estimate how long completion of the processing of each of those calls is likely to take, i.e., how long it will be before the agents who are processing those calls become available to handle the waiting calls. The estimated times are then used as the predicted wait times of that plurality of the waiting calls. The technique is applicable to workflow management in general.

Abstract: Arrangement for Clock Supply of High Bit Rate Switching Network Structures The invention is directed to on arrangement for clock supply of high bit-rate switching network structures in a digital narrow band switching system such as EWSD. A clock frequency signal (CLK2) traditionally generated with a crystal-controlled oscillator (11) as well as a corresponding frame clock signal (FMR2) are converted into low-voltage CMOS level signals and supplied to a system PL1 (2) for high frequencies. This contains a discretely constructed VCO 6 with a sine oscillator that derives a higher-frequency signal from the supplied clock signal and converts this into a high-frequency clocks signal (CLK92) of the output side.  A feedback signal derived in this part serves as input-side feedback signal for a phase detector (8) in low-voltage CMOS technology. The feedback signal as well as the output-side high-frequency signal (CLK92) also serve for phase decoupling of the input-side frame clock signal (FMB2) from the output-side frame clock signal (FMB92) and for the phase-coupling thereof to the output-side high-frequency signal (CLK92). The input-side clock signals (CLK92, PMR92) arc distributed in pairs via a clock distribution system (3) dimensioned within narrow tolerances and are supplied to respective application-specific or, respectively, customized ~Cs (4) in low-voltage CMOS technology. This division onto various stages and onto components of different technologies in low-voltage technology allow the dimensioning and configuration with cost beneficial component.

Title: A method for the production of transgenic plants using apical shoot tips
Inventor: TROLINDER NORMA L
IPC: A01H5/00
Filed: 1999-02-18
Abstract: This application provides a method for transformation of cells of plant tissues and the regeneration of these cells and tissues into mature transgenic plants. The apical meristematic region of a plant seedling are isolated, then treated to slow the metabolic activity of the isolated tissue. The tissue is then exposed to a transforming agent such as a DNA plasmid or an Agrobacterium carrying a plasmid vector which contains a DNA encoding a gene of interest.  After an appropriate incubation period, the treatment is reversed, allowing the metabolic activity of the apical meristematic tissues to return to normal.  The method provides a larger population of receptive cells for exposure to the transforming agents, thereby providing higher probabilities of isolating transformed tissues which can be regenerated into transformed plants.

Abstract: The invention relates to implementation of multiple simultaneous calls for a mobile station in a mobile communication system. A  common traffic channel (TCH) is allocated to several simultaneous calls (applications 1-n) of the mobile station (MS), so that the calls share the capacity of the common channel. Logical links are established for each call inside a common radio link protocol or link access control protocol, which is established over the common traffic channel between the mobile station (MS) and an interworking function (IWF).  The common traffic channel (TCH) is allocated when the first call or calls are set up, and the capacity of the traffic channel is adjusted dynamically during the calls. The capacity of the common traffic channel is increased or the allocatd capacity is reallocated when a new call is added to the traffic channel. Correspondingly, the capacity is decreased or the allocated capacity is reallocated when a call is cleared from the common traffic channel. The common traffic channel is released after the last call has been cleared.
