Abstract

According to one embodiment, a wireless transmission device includes: a transmitter that transmits a signal to an external device; an internal rechargeable battery that supplies a power to the transmitter; a connector to which an external rechargeable battery inserted from outside is connected; and a controller that controls the internal rechargeable battery and the external rechargeable battery so that the external rechargeable battery recharges the internal rechargeable battery when the external rechargeable battery is connected to the connector, wherein the external rechargeable battery is charged when the transmitter transmits the signal to the external device.

Claims

1. A wireless transmission device comprising:

a main body comprising;

a housing;

a first connector associated with the housing;

a transmitter within the housing, the transmitter configured to wirelessly transmit a signal for an external device; and

a first battery within the housing, the first battery configured to supply power to the transmitter;

a wireless receiver unit comprising;

a casing formed to be attachable to the housing of the main body;

a second connector associated with the casing, the second connector configured to be connectable with the first connector and with a third connector associated with the external device;

a receiver within the casing, the receiver configured to wirelessly receive the signal sent from the transmitter to convey it to the external device when the second connector is connected to the third connector associated with the external device; and

a second battery within the casing, the second battery configured to be charged by the external device when the second connector is connected to the third connector associated with the external device, and to recharge the first battery while the second connector is connected to the first connector.

2. The wireless transmission device of claim 1, wherein the first connector is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

3. The wireless transmission device of claim 1, wherein the second connector is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

4. The wireless transmission device of claim 1, wherein the first connector is configured to connect to the third connector associated with the external device with a cable, and wherein the transmitter is configured to transmit the transmission signal to the external device through the first connector and the cable when the first connector is connected to the third connector via the cable.

5. The wireless transmission device of claim 4, wherein the cable is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

6. The wireless transmission device of claim 1, wherein the first connector is configured to connect to the third connector associated with the external device with a cable, and wherein the first battery is configured so that the external device recharges the first battery through the connector and the cable when the first connector is connected to the third connector via the cable.

7. The wireless transmission device according to claim 6, wherein the cable is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

8. The wireless transmission device according to claim 1, wherein the wireless transmission device comprises a computer mouse.
