Title: System and method of controlling access to data in a computer network
Inventor: BYFORD DERRICK JOHN
IPC: H04M3/00
Filed: 1997-01-22
Abstract: A system for controlling data access in a computer network comprises first means for establishing a first communication link between a client computer and a server computer. The client sends a request to the server for supply of a data item from the server to the client. The server selects the requested data item from a store of data items in response to the request from the client. The server associates each data item in the store with a service telephone number. The server also identifies a subscriber telephone number associated with the request. A second communication link is then established between the server and a telephone utility. The server instructs the telephone utility to register a telephone call from the subscriber telephone number to the service telephone number associated with the requested data item. The requested data item is supplied from the server to the client on receipt by the server of confirmation from the telephone utility that the telephone call is registered.

Patent CH-657958G-A3 (CH)
IPC: G04C3/14
Filed: 1983-12-16
Abstract: Circuits are provided for avoiding misdetection of a non-rotated condition after driving the timepiece stepping motor. Voltages induced in the rotor coil by external high frequency magnetic fields, and current produced in the coil by lower frequency AC magnetic fields are detected. When a high frequency or AC magnetic field of sufficient intensity to cause a false indication of motor rotation is detected, the motor is next driven with a pulse having greater width than the normal driving pulse so as to assure operation of the motor. A period is provided, before the normal driving pulse would be applied, to detect AC magnetic fields and a period preceding the period for detection of AC magnetic fields is provided for detection of high frequency magnetic fields. A comparator or inverter is used to determine whether the levels of external magnetic fields are sufficient to cause misdetection of rotor position.
