Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
A multichannel radio apparatus comprising in combination: a transceiver including a frequency synthesiser and programmable storage means for storing predetermined channel frequency information; a remotely mountable control unit coupled to said transceiver, said control unit including means for selecting any one of a plurality of channels and an electrically alterable storage means, said electrically alterable storage means storing preselected addresses of locations in the programmable storage means which relate to said predetermined plurality of channels, said control unit further including an externally accessible interface adapted to operatively couple said electrically alterable storage means to a data transfer unit for programming or reprogramming the preselected addresses stored in such electrically alterable storage means to thereby change the channel frequency information for said plurality of channels.
Claim 2
Dependent Claim
124 words
A multichannel radio apparatus comprising in combination: a transceiver including a frequency synthesiser and programmable storage means for storing predetermined channel frequency information; a remotely mountable control unit coupled to said transceiver, said control unit including means for selecting any one of a plurality of channels and an electrically alterable storage means, said electrically alterable storage means storing preselected addresses of locations in the programmable storage means which relate to said predetermined plurality of channels, said control unit further including an externally accessible interface adapted to operatively couple said electrically alterable storage means to a data transfer unit for programming or reprogramming the preselected addresses stored in such electrically alterable storage means to thereby change the channel frequency information for said plurality of channels.
Claim 3
Dependent Claim
25 words
An apparatus as claimed in claim 1, wherein said progammable storage means comprises a PROM which stores data to be supplied to said frequency synthesiser.
Claim 4
Dependent Claim
16 words
An apparatus as claimed in claim 1, wherein said electrically alterable storage means comprises an EAROM.
Claim 5
Dependent Claim
18 words
An apparatus as claimed in claim 1, wherein said electrically alterable storage means comprises an E 2 PROM.
Claim 6
Dependent Claim
31 words
An apparatus as claimed in claim 1, wherein said data transfer unit comprises a non-volatile memory for storing data to be used for programming or reprogramming said electrically alterable storage means.
Claim 7
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said control unit further includes means for inhibiting the power supply to the transceiver when said electrically alterable storage means is being programmed or reprogrammed by said data transfer unit.
Claim 8
Dependent Claim
47 words
An apparatus as claimed in claim 6, wherein said control unit further comprises a power supply and said interface includes a connection to said power supply whereby said data transfer unit derives its power from said power supply when programming or reprogramming the electrically alterable storage means.
Claim 9
Dependent Claim
82 words
An apparatus as claimed in claim 1, wherein said externally accessible interface comprises a first part of a two-part connector coupled to said control unit by a flexible lead, a second, complementary part of said two-part connector being coupled to said data transfer unit; and wherein said control unit further comprises means to prevent spurious signals from being produced when the data transfer unit is disconnected from the connector and/or allowing extraneous signals from affecting the normal operation of the control unit.
