Abstract
Computer locking systems, methods and devices are disclosed. A controller (102) is configured to monitor, based on signals from a sensor (104), presence of a user in front of the sensor (104). In addition, the controller (102) determines, based on the signals from the sensor (104), that a user is not present in front of the sensor (104) and, in response to determining that the user is not present in front of the sensor (104) based on the sensor signals, transmits a keystroke code to a computer (106). Here, the keystroke code is configured to cause the computer (106) to implement a computer lock.
Claims18
A computer locking system comprising:
- a sensor;
- and
- a controller, wherein the controller is configured to monitor, based on signals from the sensor, presence of a user in front of the sensor, to determine, based on the signals from the sensor, that a user is not present in front of the sensor and, in response to determining that the user is not present in front of the sensor based on the sensor signals, to transmit a keystroke code to a computer, wherein the keystroke code is configured to cause the computer to implement a computer lock,
- wherein the keystroke code denotes a simultaneous selection of multiple keys that is defined as a screen lock code by an operating system of the computer.
A computer locking system comprising:
- a sensor;
- and
- a controller, wherein the controller is configured to monitor, based on signals from the sensor, presence of a user in front of the sensor, to determine, based on the signals from the sensor, that a user is not present in front of the sensor and, in response to determining that the user is not present in front of the sensor based on the sensor signals, to transmit a keystroke code to a computer, wherein the keystroke code is configured to cause the computer to implement a computer lock,
- wherein the controller is configured to recognize a face of the user, and
- wherein the controller is configured to determine that the user is present in front of the sensor based on additional signals output by the sensor and, in response to determining that the user is present in front of the sensor, the controller is configured to transmit an additional keystroke code to the computer that is a user's password for unlocking the computer.
A computer locking method comprising:
- monitoring presence of a user in front of a sensor;
- determining, based on signals from the sensor, that a user is not present in front of the sensor;
- and
- in response to determining that the user is not present in front of the sensor based on the sensor signals, transmitting a keystroke code to a computer, wherein the keystroke code is configured to cause the computer to implement a computer lock,
- wherein the keystroke code denotes a simultaneous selection of multiple keys that is defined as a screen lock code by an operating system of the computer.
