1. A system comprising:
- a first wireless transmitting unit configured to transmit a first signal comprising a leading portion and a data portion different from the leading portion, the leading portion comprising a first waveform signal having a first wavelength;
a second wireless transmitting unit configured to transmit a second signal comprising a leading portion and a data portion different from the leading portion, the leading portion comprising a second waveform signal having a second wavelength different from the first wavelength; and
a wireless receiving unit configured to receive the first signal and the second signal and determine the first signal was transmitted by the first wireless transmitting unit based on the first wavelength and the second signal was transmitted by the second wireless transmitting unit based on the second wavelength.

Abstract
The wireless human input device comprises at least one wireless human transmitting unit and a wireless human receiving unit. The wireless human transmitting unit generates leading signals and data signals and transmits the signals to the wireless human receiving unit. The wireless human receiving unit receives all of the leading signals and identifies the data signals based on the leading signals so as to distinguish the data signals being transmitted by which wireless human transmitting unit.

10. A wireless receiving unit for use with a plurality of wireless transmitting units, each wireless transmitting unit transmitting a signal having a leading portion and a data portion different from the leading portion, the leading portion comprising a waveform signal, each of the waveform signals transmitted by the plurality of wireless transmitting units having a different wavelength, the wireless receiving unit comprising:
-
a wireless receiving module configured to receive the signals transmitted by the plurality of wireless transmitting units; and an electronic circuit configured to distinguish the signals received from one another based on differences in the wavelengths of the waveform signals of the leading portions of the received signals. - View Dependent Claims (11, 12)
