Portable computing device and headset interface
First Claim
1. A method of authenticating the interoperability of a headset, having a speaker and a microphone, and a device, the method comprising:
- coupling the headset and device together with a cord having a speaker line coupled with the speaker and a microphone line coupled with the microphone;
in the headset, converting electrical signals from the device into power for the headset using a parasitic power circuit coupled with at least one of the speaker line or the microphone line of the cord;
using a modem circuit powered in the headset and coupled with at least one of the speaker line or the microphone line, monitoring at least one input on at least one of the speaker line or the microphone line for a verification signal from the device; and
in response to failing to detect the verification signal within a predetermined period of time, selectively disabling at least one of the speaker or the microphone of the headset.

Abstract
A method of authenticating the interoperability of a headset and a device, as well as a headset and a device, is provided. The method includes, in a headset, monitoring at least one input for a verification signal, and, in response to failing to detect the verification signal within a predetermined period of time, selectively disabling a speaker and/or microphone of the headset. An alternative method includes, in a device, detecting a coupling of a headset to the device, transmitting a verification signal to the headset, and receiving, from the headset, at least one of a serial number associated with the headset, an identification of a user of the headset, a security certificate, or a voice translation template associated with the user.

13. A method of authenticating the interoperability of a headset, having a speaker and a microphone, and a device, the method comprising:
-
coupling a headset and device together with a cord having a speaker line coupled with the speaker and a microphone line coupled with the microphone; detecting the coupling of the headset to a device; sending electrical signals to the headset from the device with at least one of the speaker line or the microphone line of the cord and converting the electrical signals from the device into power for the headset using a parasitic power circuit; transmitting a verification signal to the headset; using a modem circuit powered in the headset and coupled with at least one of the speaker line or the microphone line, sending from the headset, at least one of a serial number associated with the headset, an identification of a user associated with the headset, a security certificate, or a voice translation template associated with the user. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A headset, comprising:
-
a cord having having at least a speaker line and a microphone line a speaker coupled to the speaker line; a microphone coupled to the microphone line; a modem circuit coupled with at least one of the speaker line or the microphone line and configured to send and receive data; a parasitic power circuit coupled with at least one of the speaker line or the microphone line and operable for converting electrical signals on at least one of those lines to power for the headset; a processing unit; and a memory including program code, the program code configured to be executed by the processing unit to authenticate the interoperability of the headset and a device, the program code further configured to monitor, with the modem circuit, at least one input of the headset from a device for a verification signal and, in response to failing to detect the verification signal within a predetermined period of time, selectively disable at least one of the speaker or the microphone. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A device, comprising:
-
a processing unit; headset interface circuitry; and a memory including program code; the processing unit, memory and interface circuitry operable to provide modem communications with a headset that is coupled to the headset interface circuitry with a cord having a speaker line and a microphone line; the program code configured to be executed by the processing unit to detect a coupling of a headset to the device and to send electrical signals to the headset from the device over at least one of the speaker line or the microphone line of the cord to be converted into power for the headset using a parasitic power circuit; the program code further configured to transmit a verification signal to the headset, and to receive, from the headset, at least one of a serial number associated with the headset, an identification associated with a user of the headset, a security certificate, or a voice translation template associated with the user. - View Dependent Claims (33, 34, 35, 36, 37, 38)
