Systems and methods for controlling sensor devices in mobile devices

摘要

Systems and methods for controlling one or more sensor devices are disclosed. In one embodiment, a system of a mobile device for controlling one or more sensor devices comprises an application processor (AP), a low power personal area network (PAN) module configured to wirelessly communicate with an external device for establishing a connection with the external device, at least one sensor device, and a controller coupled to the AP, the low power PAN module and the at least one sensor device. The controller is configured to monitor a connection request signal communicated from the external device via the low power PAN module while the AP is in a sleep mode, and generate sensor data by processing each signal from the at least one sensor device during the sleep mode, where the controller is supplied with quiescent current from a battery of the mobile device during the sleep mode.

1. A system of a mobile device for controlling at least one sensor device, the system comprising:
the at least one sensor device; an application processor (AP); a low power personal area network (PAN) module configured to wirelessly communicate with an external device for establishing a connection with the external device; a controller coupled to the AP, the low power PAN module, and the at least one sensor device, wherein the at least one sensor is directly coupled to the controller, but is not directly coupled to the AP, the controller configured to:
monitor a connection request signal communicated from the external device via the low power PAN module while the mobile device is in a sleep state, wherein when the mobile device is in the sleep state, a quiescent current is supplied to the controller while the quiescent current is not supplied to the AP from a battery of the mobile device;connect the low power PAN module with the external device based on the connection request signal monitored;receive each signal directly from the at least one sensor device in response to the connection request signal;generate sensor data by processing the received each signal; andforward the sensor data to the external device via the low power PAN module, wherein the sleep state of the mobile device is maintained during the connecting, the receiving, the generating, and the forwarding.
