Abstract
Abstract A two-way communication system for transmitting command signals to and receiving operating data from a winning machine utilized in underground mining operations. The system includes a send-receive facility positioned remote from the winning machine for transmitting command information to the winning machine. A receiving means is positioned at the winning machine for receiving signals sent by the send-receive facility, and a transmitting means is positioned at the winning machine for transmitting signals corresponding to operating data of the winning machine. The send-receive facility receives the information transmitted by the transmitting means, and a separable memory is separably attached to the send-receive facility for storing such operating data and the command information. Because the memory is separable, the memory may be removed to allow the data contained therein to be analyzed at a remote location.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
175 words
A two-pay communication system for transmitting command signals to and receiving operating data from a winning machine used in underground mining operations, said system including: a send-receive facility housed in a protective casing remote from said winning machine for transmitting operating instructions to said winning machine and for receiving operating data from said winning machine. receiving means positioned at the winning machine for receiving said operating instructions transmitted by the send-receive facility; control means electrically coupled to said receiving means for controlling said winning machine in response to said operating instructions received by said receiving means and for generating operating data responsive to operation of said winning machine; transmitting means electrically coupled to said control means for transmitting said operating data to the send-receive facility; and memory means housed in said protective casing for storing instructions data corresponding to the operating instructions transmitted to the winning machine and for storing the operating data received from the winning machine, said memory means being physically separable from said casing at a location remote to said winning machine.
Claim 2
Dependent Claim
175 words
A two-pay communication system for transmitting command signals to and receiving operating data from a winning machine used in underground mining operations, said system including: a send-receive facility housed in a protective casing remote from said winning machine for transmitting operating instructions to said winning machine and for receiving operating data from said winning machine. receiving means positioned at the winning machine for receiving said operating instructions transmitted by the send-receive facility; control means electrically coupled to said receiving means for controlling said winning machine in response to said operating instructions received by said receiving means and for generating operating data responsive to operation of said winning machine; transmitting means electrically coupled to said control means for transmitting said operating data to the send-receive facility; and memory means housed in said protective casing for storing instructions data corresponding to the operating instructions transmitted to the winning machine and for storing the operating data received from the winning machine, said memory means being physically separable from said casing at a location remote to said winning machine.
Claim 3
Dependent Claim
42 words
The communication system of claim 1 wherein said send-receive facility includes a modulator, a demodulator, a high frequency transmitter, a high frequency receiver, a display means and a power supply means electrically coupled so as to form a two-way radio frequency transmitter/receiver.
Claim 4
Dependent Claim
26 words
The communication system of claim 2 wherein said send-receive facility further includes a keypad input means for inputting data to be transmitted by the send-receive facility.
Claim 5
Dependent Claim
18 words
The communication system of claim 1 wherein said separable memory means is electrically coupled to the send-receive facility.
Claim 6
Dependent Claim
18 words

Claim 8
Dependent Claim
125 words
A send-receive facility for sending operating instructions to and receiving operating data from a winning machine utilized in underground mining operations, said facility including means forming a radio frequency transmitter and receiver, including a protective casing enclosing a modulator, a demodulator, a high frequency transmitter, a high frequency receiver, a power supply means, and memory means, said memory means being coupled within said protective casing for storing data corresponding to the operating instructions transmitted to the winning machine and for storing operating data received from the winning machine, said memory means being decoupled and physically separable from said protective casing to allow evaluation of said instruction data and said operating data stored therewith at a location remote to the winning machine and the protective casing.
Claim 9
Dependent Claim
125 words
A send-receive facility for sending operating instructions to and receiving operating data from a winning machine utilized in underground mining operations, said facility including means forming a radio frequency transmitter and receiver, including a protective casing enclosing a modulator, a demodulator, a high frequency transmitter, a high frequency receiver, a power supply means, and memory means, said memory means being coupled within said protective casing for storing data corresponding to the operating instructions transmitted to the winning machine and for storing operating data received from the winning machine, said memory means being decoupled and physically separable from said protective casing to allow evaluation of said instruction data and said operating data stored therewith at a location remote to the winning machine and the protective casing.
Claim 10
Dependent Claim
14 words
