Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
A cellular telephone system, said system comprising: A. a cellular telephone transceiver; B. one or more peripheral devices; and C. system interconnection means for connecting the transceiver to each of the peripheral devices, the system interconnection means including: i. audio signal interconnection means for passing an audio signal between the transceiver and the peripheral devices, ii. information signal interconnection means for passing an information signal between the transceiver and the peripheral devices, iii. control signal interconnection means for passing a control signal between the transceiver and the peripheral devices, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that a peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from a peripheral device.
Claim 2
Dependent Claim
155 words
A cellular telephone system, said system comprising: A. a cellular telephone transceiver; B. one or more peripheral devices; and C. system interconnection means for connecting the transceiver to each of the peripheral devices, the system interconnection means including: i. audio signal interconnection means for passing an audio signal between the transceiver and the peripheral devices, ii. information signal interconnection means for passing an information signal between the transceiver and the peripheral devices, iii. control signal interconnection means for passing a control signal between the transceiver and the peripheral devices, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that a peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from a peripheral device.
Claim 3
Dependent Claim
45 words
The system of claim 1 wherein the second portion of the control signal comprises either the first predetermined logical state or a second predetermined logical state which exists for a second predetermined period of time following the expiration of the first predetermined period of time.
Claim 4
Dependent Claim
53 words
The system as in claim 2 wherein the control signal includes a third portion which comprises the first predetermined logical state which exists for a third predetermined period of time, following the expiration of the second predetermined period of time, during which information may be transmitted from a peripheral device to the transceiver.
Claim 5
Dependent Claim
132 words
A cellular telephone transceiver, said transceiver comprising: A. audio signal interconnection means for passing audio signals between the transceiver and one or more peripheral devices; B. information signal interconnection means for passing information signals between the transceiver and one or more peripheral devices; and C. control signal interconnection means for receiving a control signal from or transmitting a control signal to one or more peripheral devices, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that a peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from a peripheral device.
Claim 6
Dependent Claim
132 words
A cellular telephone transceiver, said transceiver comprising: A. audio signal interconnection means for passing audio signals between the transceiver and one or more peripheral devices; B. information signal interconnection means for passing information signals between the transceiver and one or more peripheral devices; and C. control signal interconnection means for receiving a control signal from or transmitting a control signal to one or more peripheral devices, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that a peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from a peripheral device.
Claim 7
Dependent Claim
46 words
The transceiver as in claim 4 wherein the second portion of the control signal comprises either the first predetermined logical state or a second predetermined logical state which exists for a second predetermined period of time following the expiration of the first predetermined period of time.
Claim 8
Dependent Claim
53 words
The transceiver as in claim 5 wherein the control signal includes a third portion which comprises the first predetermined logical state which exists for a third predetermined period of time, following the expiration of the second predetermined period of time, during which information may be transmitted from a peripheral device to the transceiver.
Claim 9
Dependent Claim
131 words
A peripheral device for use with a cellular telephone transceiver, said device comprising: A. audio signal interconnection means for passing audio signals between the peripheral device and a cellular telephone transceiver; B. information signal interconnection means for passing information signals between the peripheral device and the transceiver; and C. control signal interconnection means for passing a control signal between the peripheral device and the transceiver, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that the peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from the peripheral device.
Claim 10
Dependent Claim
131 words
A peripheral device for use with a cellular telephone transceiver, said device comprising: A. audio signal interconnection means for passing audio signals between the peripheral device and a cellular telephone transceiver; B. information signal interconnection means for passing information signals between the peripheral device and the transceiver; and C. control signal interconnection means for passing a control signal between the peripheral device and the transceiver, the control signal including at least first and second portions, the first portion comprising a first predetermined logical state which exists for a first predetermined period of time for indicating that the peripheral device is ready to transmit information to the transceiver through the information signal interconnection means, and the second portion for indicating whether the transceiver is ready to receive information from the peripheral device.
Claim 11
Dependent Claim
47 words
