摘要:
A service multiplexer (2) for connecting a plurality of signal sources to a public switched communication network transfers data in the form of a synchronously transferred data cells from a plurality of inputs (4) to an output (6) for connection to the network. The multiplexer (2) includes a bandwidth control unit which receives a bandwidth control signal from the network representative of available bandwidth for transmission of cells to the network and generates feedback control signals for transmission to the signal sources to cause them to alter their data transmission rates in accordance with the available bandwidth. An activity detector coupled to the bandwidth control unit monitors the bandwidth of data received at the inputs. The multiplexer allows ABR (available bit rate)—commandable signal sources to be linked to a single port of a public network operating on an ABR basis to provide an efficient and fair allocation of bandwidth for each source.

A network for ATM signals includes source end systems SES1, SES3 connected by a permanent virtual connection PVC1 through switch SW1 . . . SWN. Dynamic bandwidth controllers DBC1, DBC2 operate as virtual source/virtual destinations. The individual switches, such as switch SW2 have associated rate controllers RC1 which determine the available bandwidth for the signal path PVC1. Dynamic bandwidth controller DBC1 interrogates the rate controller RC1, RC2 using resource management RM signals which cascade from switching node to switching node along the path in a forward direction and then in a backward direction. The DBC's communicate with the SES's using RM signals which may be of a different format to the RM signals which pass from switching node to switching node.

A broadband switching system and method switches asynchronously transferred cells of data using a dynamic bandwidth controller to control application of data cells from a number of transmitting end systems to an input port of the system. The dynamic bandwidth controller provides cell buffering from each source and controls output of data cells to the system according to a current cell rate assigned to cells from the respective end system. When an end system begins transmitting data cells, the controller detects the presence of incoming cells and requests bandwidth from a connection admission control forming part of the system. A default cell rate is provided for the end system so that transmission can continue until an appropriate bandwidth is allocated. The controller contains a buffer for buffering cells in this situation. Once appropriate bandwidth has been allocated, cell rate advice information from the connection admission control is fed back to the data bandwidth controller and thence to the transmitting end system to prevent transmission of cells at too high a rate for the available bandwidth.

Dispensing units for dispensing items, such as in a healthcare facility, are linked in a network. The dispensing units use a fingerprint to authenticate users. The fingerprints on a short list reflect recent authorization, and permit access without other identifying information. Dispensing units in the network may use different fingerprint scanning technologies, but are made compatible by enrolling fingerprints using the different technologies. Two or more reference fingerprints may be stored at a dispensing unit, permitting either a primary fingerprint or alternate fingerprint to gain access to that dispensing unit. During enrollment of a user, fingerprints for a user may be “fast tracked” for registration based upon a quality determination.

The invention provides a method to detect an abnormal condition or disease state by assessing a characteristic response pattern of responder cells to indicators contained in a biological fluid of a subject. A characteristic disease-associated pattern can be obtained by determining the response pattern of responder cells to that of bodily fluids or fractions thereof from subjects known to exhibit a particular abnormal condition optionally comparing said pattern to such pattern elicited by fluids or fractions from normal subjects and identifying elements that differ. The identified elements constitute a characteristic or differential pattern which can then be used to identify the presence or stage of a disease in a test subject.
