  • Patent number: 9059597
    Abstract: Systems, circuits, and devices for reducing leakage current in a mobile device with an embedded battery are disclosed. In one embodiment, a system for reducing leakage current in a mobile device with an embedded battery comprises a power management integrated circuit (PMIC), a switch device electrically coupled to the embedded battery and the PMIC, and a low power personal area network (PAN) module coupled to the embedded battery, the PMIC, and the switch device. The low power PAN module is configured to maintain the switch device in an open state while an application processor (AP) of the mobile device is off and to close the switch device in response to a receipt of an AP ON request signal to wake up the AP, where the open state of the switch device blocks leakage current flowing from the battery to the PMIC.

  • Patent number: 8918148
    Abstract: 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.

  • Patent number: 8830889
    Abstract: Systems for waking up an application processor (AP) of a mobile device are disclosed. In one embodiment, one of the systems of the mobile device includes a Bluetooth device with Bluetooth Low Energy (BLE) feature configured to receive a connection request signal from an external device and a hardware module coupled to the Bluetooth device with BLE feature. The hardware module is configured to forward an AP ON request signal received from the external device via the Bluetooth device with BLE feature if the pairing request signal is determined to be valid, and wherein the Bluetooth device with BLE feature and the hardware module are supplied with quiescent current from a battery of the mobile device prior to the wake up of the AP.
