Abstract

Abstract A mobile electric accessory apparatus for mounting on a vehicle equipped with a wireless transceiver unit such as a mobile radiotelephone and a separate wireless receiver unit such as a television receiver is adapted to limit operation of the wireless receiver unit, as by cutting off power thereto or inhibiting reception of a signal from the corresponding receiving antenna, when the wireless transceiver unit is being used, thereby preventing interference in the reception of the wireless receiver unit. If a receiving antenna nearest the transceiver antenna of the transceiver unit, when the latter is in use, is excluded from the antennas in a diversity reception system, good reception can be obtained. By disposing antenna for the transceiver unit and the antenna for the receiver unit on a single windshield glass adjacent mutually opposing edges thereof, the receiver unit will not have its reception disturbed by electric waves from the transceiver unit.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 175 words
An apparatus for a vehicle having a wireless transceiver unit and a separate wireless receiver unit, comprising: multiple receiving antennas for receiving electric waves for said wireless receiver unit, wherein one of the antennas of said multiple receiving antennas can be selectively connected to the wireless receiver in relationship to use of said transceiver unit; a transceiving antenna, located elsewhere from the multiple receiving antennas, for transmitting and receiving electric waves for said wireless transceiver unit; detecting means, operatively connected to said wireless transceiver unit, for detecting when the wireless transceiver unit is being used, and for providing an output signal in relationship thereto; and control means, operatively connected to said detecting means, for receiving the output signal from said detecting means when the detecting means detects that the transceiver unit is being used and for selecting an appropriate receiving antenna from said multiple receiving antennas for said wireless receiver unit in response to the output signal of said detecting means such that interference for the selected receiving antenna from the transceiving antenna is minimized.
Claim 2
Independent Claim 175 words
An apparatus for a vehicle having a wireless transceiver unit and a separate wireless receiver unit, comprising: multiple receiving antennas for receiving electric waves for said wireless receiver unit, wherein one of the antennas of said multiple receiving antennas can be selectively connected to the wireless receiver in relationship to use of said transceiver unit; a transceiving antenna, located elsewhere from the multiple receiving antennas, for transmitting and receiving electric waves for said wireless transceiver unit; detecting means, operatively connected to said wireless transceiver unit, for detecting when the wireless transceiver unit is being used, and for providing an output signal in relationship thereto; and control means, operatively connected to said detecting means, for receiving the output signal from said detecting means when the detecting means detects that the transceiver unit is being used and for selecting an appropriate receiving antenna from said multiple receiving antennas for said wireless receiver unit in response to the output signal of said detecting means such that interference for the selected receiving antenna from the transceiving antenna is minimized.
Claim 3
Dependent Claim 79 words
The apparatus according to claim 1, wherein said multiple receiving antennas are provided at least at two multiple positions, said control means selects whichever receiving antenna of said multiple receiving antennas gives the best reception when said detecting means detects that said wireless transceiver unit is not being used, and excludes rom selection whichever receiving antenna of said multiple receiving antennas is nearest said transceiving antenna when said detecting means detects that said wireless transceiving unit is being used.
Claim 4
Dependent Claim 35 words
The apparatus according to claim 1, wherein said detecting means detects that said wireless transceiver unit is being used by detecting a change in electric field strength that accompanies use of said wireless transceiver unit.
Claim 5
Dependent Claim 15 words
The apparatus according to claim 1, wherein said wireless transceiver unit is a mobile radiotelephone.
Claim 6
Dependent Claim 32 words
The apparatus according to claim 4, wherein said detecting means detects that said mobile radiotelephone is being used by detecting that a handset of said radiotelephone has been taken off a hook.
Claim 7
Dependent Claim 19 words
The apparatus according to claim 1, wherein said wireless receiver unit is a unit for receiving broadcast electric waves.
Claim 8
Dependent Claim 20 words
The apparatus according to claim 6, wherein said wireless receiver unit is a television receiver for receiving broadcast electric waves.
Claim 9
Independent Claim 149 words
An apparatus for a vehicle having a wireless transceiving unit for wireless communication and a separate wireless receiving unit, comprising: at least one transceiving antenna for transmitting and receiving electric waves for said wireless transceiver unit; one or more receiving antennas disposed in the vehicle for receiving electric waves for said wireless receiving unit; detecting means, operatively connected to said wireless transceiver unit, for detecting when said wireless transceiver unit is being used, and for providing an output signal in relationship thereto; and control means, operatively connected to said detecting means, for receiving the output signal from said detecting means when the detecting means detects that the transceiver unit is in use, and for turning the power off of the wireless receiver unit in response to the output signal of said detecting means such that interference for the transceiving antennas from the one or more receiving antennas is eliminated.
Claim 10
Independent Claim 149 words
An apparatus for a vehicle having a wireless transceiving unit for wireless communication and a separate wireless receiving unit, comprising: at least one transceiving antenna for transmitting and receiving electric waves for said wireless transceiver unit; one or more receiving antennas disposed in the vehicle for receiving electric waves for said wireless receiving unit; detecting means, operatively connected to said wireless transceiver unit, for detecting when said wireless transceiver unit is being used, and for providing an output signal in relationship thereto; and control means, operatively connected to said detecting means, for receiving the output signal from said detecting means when the detecting means detects that the transceiver unit is in use, and for turning the power off of the wireless receiver unit in response to the output signal of said detecting means such that interference for the transceiving antennas from the one or more receiving antennas is eliminated.
Claim 11
Dependent Claim 78 words
The apparatus according to claim 8, wherein multiple receiving antennas are provided at least at two different positions, said control means selects whichever receiving antennas of said multiple receiving antennas gives the best reception when said detecting means detects that said wireless transceiver unit is not being used, and excludes from selection whichever receiving antenna of said multiple receiving antennas is nearest said transceiving antenna when said detecting means detects that said wireless transceiving unit is being used.
Claim 12
Dependent Claim 35 words
The apparatus according to claim 8, wherein said detecting means detects that said wireless transceiver unit is being used by detecting a change in electric field strength that accompanies use of said wireless transceiver unit.
Claim 13
