Abstract
Disclosed is a peripheral device, comprising a sensor to trip when in proximity to a host device, and a transmitter coupled to the sensor to transmit a bind request to a host device. Further described is a method of binding the peripheral device to a host device.
Claims21
A peripheral device, comprising:
- a proximity sensor configured to:
- detect that the peripheral device is within a selected proximity range of a host device in response to sensing a proximity sensor activator of the host device, and
- signal the peripheral device to operate in a pairing mode, based on the detection;
- a bind logic circuit coupled to the proximity sensor, the bind logic circuit being configured to provide a bind request when the peripheral device is operating in the pairing mode;
- and
- a transmitter coupled to the proximity sensor and to the bind logic circuit, and configured to repeatedly transmit the bind request to the host device over at least one pairing channel, the bind request transmitted to the host device including a data channel identifier to direct the host device to a data channel to be used for a later transmission of data from the peripheral device to the host device, wherein a transmit power of the transmitter is reduced when the peripheral device enters the pairing mode to transmit the bind request within a reduced communication range.
3 more elements
A wireless system, comprising:
- a peripheral device;
- and
- a host device including:
- a host receiver configured to receive wireless communications from the peripheral device, and
- a proximity sensor activator, the peripheral device including:
- a proximity sensor configured to be triggered by a signal from the proximity sensor activator when the proximity sensor detects that the peripheral device is located within a selected proximity to the host device,
- a bind logic circuit coupled to the proximity sensor to initiate repeated transmission of a bind mode request from the peripheral device to the host receiver based on the proximity sensor being triggered,
- the bind mode request identifying a communication channel to be used by the peripheral device to communicate data to the host device, and
- the host receiver further configured to receive data from the peripheral device over the communication channel identified in the bind mode request;
- and
- a transmitter configured to transmit the bind mode request, wherein a transmit power of the transmitter is reduced to transmit the bind request within a reduced communication range.
8 more elements
A wireless communication device, comprising:
- a proximity sensor configured to detect that the proximity sensor is within a selected proximity range to a host wireless device through a triggering signal from the host wireless device, the triggering signal including a signature of signal patterns;
- bind logic coupled to the proximity sensor, the bind logic configured to initiate a bind operation with the host wireless device responsive to receipt by the proximity sensor of the triggering signal;
- and
- a transmitter coupled to the bind logic, the transmitter configured to transmit reduced communication range bind signals repeatedly to the host wireless device during the bind operation, the bind signals identifying a data channel to the host wireless device to be utilized for subsequent data communication from the wireless communication device to the host wireless device.
