SMART SENSOR FOR ZERO-TOUCH TRUSTED ASSOCIATION
An information handling system may include at least one processor; a wireless interface; and an ultrasonic retroreflector. In response to receiving an ultrasonic signal from a device external to the information handling system, the ultrasonic retroreflector may be configured to: transmit a reflected ultrasonic signal to the device; and cause the wireless interface to establish a wireless communications connection with the device.
1 . An information handling system comprising:
at least one processor;
a wireless interface; and
an ultrasonic retroreflector;
wherein, in response to receiving an ultrasonic signal from a device external to the information handling system, the ultrasonic retroreflector is configured to:
transmit a reflected ultrasonic signal to the device; and
cause the wireless interface to establish a wireless communications connection with the device.
2 . The information handling system of claim 1 , wherein the wireless interface is a Bluetooth interface.
3 . The information handling system of claim 1 , wherein the device is a wireless docking station.
4 . The information handling system of claim 1 , wherein the information handling system is a notebook computer system.
5 . The information handling system of claim 1 , wherein the information handling system is further configured to exit a power-saving state in response to the ultrasonic signal.
6 . The information handling system of claim 1 , wherein the information handling system is further configured to power on from a powered-off state in response to the ultrasonic signal.
7 . A method comprising:
an information handling system receiving, at an ultrasonic retroreflector thereof, an ultrasonic signal from a device external to the information handling system;
the information handling system transmitting, from the ultrasonic retroreflector, a reflected ultrasonic signal to the device; and
the information handling system causing a wireless interface thereof to establish a wireless communications connection with the device.
8 . The method of claim 7 , wherein the wireless interface is a Bluetooth interface.
9 . The method of claim 7 , wherein the device is a wireless docking station.
10 . The method of claim 7 , wherein the information handling system is a notebook computer system.
11 . The method of claim 7 , further comprising: the information handling system exiting a power-saving state in response to the ultrasonic signal.
12 . The method of claim 7 , further comprising: the information handling system powering on from a powered-off state in response to the ultrasonic signal.
13 . An article of manufacture comprising a non-transitory, computer-readable medium having computer-executable code thereon that is executable by a processor of an information handling system for:
receiving, at an ultrasonic retroreflector of the information handling system, an ultrasonic signal from a device external to the information handling system;
transmitting, from the ultrasonic retroreflector, a reflected ultrasonic signal to the device; and
causing a wireless interface of the information handling system to establish a wireless communications connection with the device.
14 . The article of claim 13 , wherein the wireless interface is a Bluetooth interface.
15 . The article of claim 13 , wherein the device is a wireless docking station.
16 . The article of claim 13 , wherein the information handling system is a notebook computer system.
17 . The article of claim 13 , wherein the information handling system is further configured to exit a power-saving state in response to the ultrasonic signal.
18 . The article of claim 13 , wherein the information handling system is further configured to power on from a powered-off state in response to the ultrasonic signal.
