This application claims priority to Taiwanese Application No. 097136310, filed Sep. 22, 2008, the disclosure of which is incorporated herein by reference.
1. Field of the Invention
This invention relates to a two-way radio handheld transceiver, more particularly to a two-way radio handheld transceiver capable of wireless reception of location information associated therewith.
2. Description of the Related Art
A two-way radio handheld transceiver, a.k.a., walkie-talkie, is well known in the art. The conventional two-way radio handheld transceiver has a microphone input port to which a global positioning system (GPS) module may be connected via a cable to thereby permit the conventional two-way radio handheld transceiver to receive location information associated therewith from the GPS module.
It is desirable to provide a two-way radio handheld transceiver capable of wireless reception of location information associated therewith.
According to an aspect of the present invention, a system comprises a location information-providing device and a two-way radio handheld transceiver. The location information-providing device is operable so as to transmit location information thereof wirelessly. The two-way radio handheld transceiver includes a receiving unit that receives the location information transmitted by the location information-providing device, and a memory unit that stores the location information received by the receiving unit.
According to another aspect of the present invention, a two-way radio handheld transceiver comprises a receiving unit and a memory unit. The receiving unit is adapted to receive location information associated therewith wirelessly. The memory unit stores the location information received by the receiving unit.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
Referring to
The location information-providing device 1 includes a processing unit 12, and a positioning module 11 and a transmitting unit 13, each of which is connected to the processing unit 12. The positioning module 11 is a global positioning system (GPS) receiver, and is operable so as to receive a GPS signal transmitted by a GPS 6, and so as to generate location information of the location information-providing device 1 based on the GPS signal received thereby. The location information includes longitude, latitude, and altitude of the location information-providing device 1. The processing unit 12 is operable so as to generate a location signal, which contains the location information. The transmitting unit 13 is operable so as to transmit the location signal wirelessly.
The two-way radio handheld transceiver 2 includes a processing unit 22, and a receiving unit 21 and a memory unit 23, each of which is connected to the processing unit 22. The receiving unit 21 is operable so as to receive the location signal transmitted by the transmitting unit 13 of the location information-providing device 1. The processing unit 22 is operable so as to extract the location information contained in the location signal received by the receiving unit 21, and so as to store the location information extracted thereby in the memory unit 23.
In this embodiment, the transmitting unit 13 of the location information-providing device 1 is a bluetooth-compliant transmitting unit, and the receiving unit 21 of the two-way radio handheld transceiver 2 is a bluetooth-compliant receiving unit.
In an alternative embodiment, the transmitting unit 13 of the location information-providing device 1 is an infrared-compliant transmitting unit, and the receiving unit 21 of the two-way radio handheld transceiver 2 is an infrared-compliant receiving unit.
It is noted that the receiving unit 21, the processing unit 22, and the memory unit 23 may be implemented as an external module, which is plugged into an input port (not shown) of the two-way radio handheld transceiver 2.
The two-way radio handheld transceiver 2 further includes a radio frequency (RF) transceiver unit 24 connected to the processing unit 22, and a short-wave (SW) antenna 27 connected to the RF transceiver unit 24. The RF transceiver unit 24 is operable so as to transmit via the SW antenna 27 the location information stored in the memory unit 23 to a locating device 3.
The processing unit 22 is capable of being actuated to control the RF transceiver unit 24 to transmit the location information. The two-way radio handheld transceiver 2 further includes a function key 28 that is connected to the RF transceiver unit 24 and that is operable so as to actuate the processing unit 22.
The two-way radio handheld transceiver 2 further includes a microphone 25 and a speaker 26, each of which is connected to the RF transceiver unit 24. The function key 28 is further operable so as to actuate the RF transceiver unit 24 to transmit via the SW antenna 27 a voice signal detected by the microphone 25. The RF transceiver unit 24 is further operable so as to receive via the SW antenna 27 a signal, which is thereafter converted by the speaker 26 into an audible signal.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
