Abstract: A method of transmitting items of information from a plurality of data sources (25-28) to a data destination (9) over a common data channel.

Abstract: An interactive, predictive game control system for use in conjunction with a live TV broadcast received by one or more remote players. The system comprises a central controller for generating game playing data for transmission with a TV broadcast to the remote player(s) and for receiving information from the remote player(s). An input device is connected to the central controller. A database is connected to the central controller for storing data relating to the content of the live broadcast and known in advance of the live broadcast. The central controller is responsive to signals from the input device: a) prior to the live broadcast, to select data from the database for transmission to the remote user(s) in advance of and/or during the live broadcast, and b) during or after the live broadcast, to record the time of occurrence of one or more events relating to the live broadcast which are to be predicted by the remote player(s), as indicated by an operator to the central controller via the input device.

Abstract: An interactive communication system comprises a central controller; and at least one remote unit connected in use to a display device, the central controller generating signals in accordance with a service function, access to all or part of which is restricted. The signals are supplied to the remote unit(s) for display on the display device. The or each remote unit includes a processor, responsive to signals from the central controller, and selectively connectable to the central controller to transmit information back to the central controller. The or each remote unit further comprises an input device and a control memory connected to the processor, the input device allowing a user to enter information, and the control memory storing access control data. The processor is responsive to the access control data to allow a user to gain access to the restricted part of the service function, and periodically supplies data to the central controller related to said access.

Abstract: An interactive system, comprising a local controller (8) operable to control data flow to and from at least two local handsets (11,22) for generating data. The local controller (8) includes a memory (28) for storing data and a processor. A central controller (1) is connectable to the local controller, and a display (12) is provided for displaying data locally from the central controller and the local controller. The local controller (8) stores data generated by each local handset and selectively transfers stored data to the central controller (1).

Abstract: Apparatus is described for controlling blood glucose concentration in a subject by selected infusion of insulin and/or glucose, depending upon the general blood glucose concentration. This apparatus comprises in combination sensor means for measuring the blood glucose concentration and for providing computer input signals based on such measurement, computer means for receiving such input signals and being programmed to provide output signals based upon such input signals, and pump means responsive to such computer output signals to supply insulin and/or glucose to such subject at a rate determined by such output signals. The computer derives the output signals in accordance with specific quadratic and biquadratic equations employing certain independently selected values relating to basal blood glucose concentrations and basal insulin and glucose infusion rates at such basal blood glucose concentrations.
