Abstract

Systems, apparatuses, and methods may include a touch device having conductive traces to receive human body communication signals and user selection signals such that the human body communication signals are multiplexed with the user selection signals on the conductive traces. A processor receives the human body communication signals and the user selection signals.

First claim

We claim:

1 . A system comprising:
a wearable human body communication device including a transmitter and receiver to send and receive human body communication signals through at least a portion of a human body; a touch device having conductive traces to receive the human body communication signals at a first frequency and user selection signals at a second frequency such that the human body communication signals and the user selection signals are multiplexed together on the conductive traces; and a processor to receive the human body communication signals and the user selection signals.

2 . The system of claim 1 , further comprising a human body communication controller communicating with the conductive traces.

3 . The system of claim 1 , further comprising a touch controller communicating with the conductive traces.

4 . The system of claim 1 , further comprising analog filters to separate the human body communication signals from the user selection signals.

5 . The system of claim 1 , wherein the wearable human body communication device further includes a wireless transmitter and receiver.

6 . The system of claim 1 , further comprising digital filters to separate the human body communication signals from the user selection signals.

7 . An apparatus comprising:
a touch device having conductive traces to receive human body communication signals at a first frequency and user selection signals at a second frequency such that the human body communication signals and the user selection signals are multiplexed together on the conductive traces; a processor to receive the human body communication signals and the user selection signals.

8 . The apparatus of claim 7 , further comprising a human body communication controller communicating with the conductive traces.

9 . The apparatus of claim 7 , further comprising a touch controller communicating with the conductive traces.

10 . The apparatus of claim 7 , further comprising analog filters to separate the human body communication signals from the user selection signals.

11 . The apparatus of claim 7 , further comprising digital filters to separate the human body communication signals from the user selection signals.

12 . The apparatus of claim 7 , further comprising a first communication path between the human body communication controller and the processor and a second communication path between the touch controller and the processor.

13 . A method comprising:
receiving, via a single touch by a user, a human body communication signal at a first frequency and a user selection signal at a second frequency different from the first frequency; multiplexing the human body communication signal and the user selection signal onto conductive traces; and distinguishing the human body communication signal from the user selection signal.

14 . The method of claim 13 , further comprising performing, by a processor, one or more actions requested by the human body communication signal and one or more actions requested by the user selection signal.

15 . The method of claim 13 , further comprising using a digital filter to separate the human body communication signal from the user selection signal.

16 . The method of claim 13 , further comprising using an analog filter to separate the human body communication signal from the user selection signal.

17 . The method of claim 13 , wherein the conductive traces are part of a touch device.

18 . The method of claim 13 , wherein the first frequency is in a range from approximately 1 MHz to approximately 60 MHz and second frequency is in a range from approximately 100 kHz to approximately 900 kHz.

19 . A non-transitory computer readable medium comprising a set of instructions which, when executed by a processor cause a local device to:
multiplex a received human body communication signal at a first frequency with a user selection signal at a second frequency different from the first frequency onto conductive traces; distinguish the human body communication signal from the user selection signal; and perform one or more actions requested by the human body communication signal and one or more actions requested by the user selection signal.

20 . The computer readable medium of claim 19 wherein distinguishing the human body communication signal from the user selection signal comprises digital filtering.

21 . The computer readable medium of claim 19 wherein distinguishing the human body communication signal from the user selection signal comprises analog filtering.
