Paging system for remote computers
First Claim
1. Apparatus for receiving data from a host computer comprising:
- a radio receiver for receiving a radio signal indicating the availability of data for a specific remote location;
decoding means for decoding said radio signal to establish an identification of the remote location for which said data is available;
control means responsive to said decoding means for generating an interrupt signal;
a connector provided with a plurality of data transmission pins;
dual in-line connection means connected for receiving said interrupt signal and applying said interrupt signal to a predetermined one of said data transmission pins;
a computer having a parallel port connected to said connector and responsive to the presence of said interrupt signal on said predetermined one of said transmission pins by temporarily suspending a program then in operation and generating a code corresponding to a telephone number for said host computer;
a modem for dialing said number, receiving said data from said host computer and relaying said data to said computer; and
switching means responsive to said control means for switching power to said computer, so that said computer is able to respond to said interrupt signal.

Abstract
A system is disclosed for supplying information in electronic form from a database to subscribers at a plurality of remote locations. Subject matter descriptors are applied to newly acquired information, and these descriptors are compared with information interest profiles maintained for all of the subscribers. Each subscriber also has an assigned identification number. A list of identification numbers is prepared as a result of the interest check, and this list of numbers is broadcast by radio transmission. The subscribers are equipped with radio receivers able to recognize their assigned numbers. When a radio receiver recognizes its identification number, it causes an associated remote computer to call the database and request transmission of the document by telephone link.

5. Apparatus for receiving data from a host computer comprising:
-
a hand-held unit including a radio receiver for receiving a radio signal indicating the availability of data for a specific remote location and decoding means for generating a magnetic field in response to the occurrence of a predetermined code in said radio signal; control means comprising a holster for removably seating said hand-held unit, a sensing band secured around said hand-held unit and attached to said holster, and means responsive to said magnetic field for generating a recognition signal; a computer responsive to said recognition signal for generating a code corresponding to a telephone number for said host computer; a modem for dialing said number, receiving said data from said host computer and relaying said data to said computer, switching means responsive to said control means for switching power to said computer, so that said computer is able to respond to said recognition signal; and dual in-line connection means having an output connector provided with a plurality of connection pins and two input connections interconnected for shared access to said connection pins;
said dual in-line connection means being connected for receiving said recognition signal on one of said input connections and delivering said recognition signal to a predetermined one of said connection pins;
said computer being connected for receiving said recognition signal from said predetermined one of said connection pins.
