A method of operation and non-transitory computer readable medium are provided for a mobile communications device which includes memory storing program instructions and a processor coupled to a first input that passively collects input data and a second input that collects response data based on a challenge. A statistical behavioral model is generated based upon passively collected input data for the user. A level of assurance (LOA) is determined based upon the statistical behavioral model and the passively collected input data from the first input. The LOA is compared with a threshold and based on the comparison: the mobile device operation is enabled as a result of determining that the LOA meets or exceeds the threshold without requiring response data from the at least one second input, otherwise, the challenge is generated and the mobile device operation is enabled responsive to valid response data from the second input.

Mobile communications device providing heuristic security authentication features and related methods

A mobile communications device includes a plurality of first input devices capable of passively collecting input data, a second input device(s) capable of collecting response data based upon a challenge, and a processor capable of determining a level of assurance (LOA) that possession of the mobile communications device has not changed based upon a statistical behavioral model and the passively received input data, and comparing the LOA with a security threshold. When the LOA is above the security threshold, the processor may be capable of performing a given mobile device operation without requiring response data from the second input device(s). When the LOA falls below the security threshold, the processor may be capable of generating the challenge, performing the given mobile device operation responsive to valid response data, and adding recent input data to the statistical behavioral model responsive to receipt of the valid response data.

Methods and devices are provided for monitoring a battery to determine whether sufficient battery power remains to perform an event at a pre-scheduled time. A communications device includes a processor that receives instructions to perform the event at the pre-scheduled time, determines a first amount of time until the event is performed, detects an idle mode of the communications device, the idle mode consuming a minimum amount of power, calculates a second amount of time until the battery is depleted, the second amount of time being calculated while the communications device operates in the idle mode, determines whether the second amount of time is less than the first amount of time, activates a first alert if the second amount of time is less than the first amount of time while remaining in the idle mode, and performs an action prior to the pre-scheduled time while remaining in the idle mode.

A wireless communications device may include a portable housing and a temperature-compensated clock circuit carried by the portable housing. The device may further include a wireless receiver carried by the portable housing for receiving timing signals, when available, from a wireless network, and a satellite positioning clock circuit carried by the portable housing. A clock correction circuit may be carried by the portable housing for correcting the temperature-compensated clock circuit based upon timing signals from the wireless network when available, and storing historical correction values for corresponding temperatures. The clock correction circuit may also correct the temperature-compensated clock circuit based upon the stored historical correction values when timing signals are unavailable from the wireless network, and correct the satellite positioning clock based upon the temperature-compensated clock circuit.

The described embodiments relate generally to methods, systems and devices for maintaining data integrity of a removable media card of a handheld electronic device, particularly when such media card is removed from such device.

Systems and methods for maintaining data integrity of removable media of an electronic device

The disclosure describes a system and method for controlling interfacing parameters for a device when connected to a host. In the system and method, the communications interface is configurable to be in operable connection to a host using a microprocessor in the device having a first bus controller and a second bus controller, the second bus controller external to the microprocessor. The method comprises: establishing an initial connection by the device; conducting negotiations by the device to set a first data transmission rate for the device for the initial connection utilizing a communication bus controller contained in the microprocessor; and after detecting completion of enumeration of the device, re-establishing the connection by the device using the second bus controller in the device that processes the communications at a second transmission rate that is higher than the first data transmission rate.

System and method for interfacing an electronic device with a host system

The invention relates to a system and method for controlling interfacing parameters for a device when connected to a host is provided. The method comprises: monitoring for an initial connection by the device to the host; then, while the device is establishing the connection with the host, utilizing a communication bus controller contained in a microprocessor in the device to process communications with the host at a first data transmission rate; and after a predetermined condition, re-establishing the connection with the host using a second bus controller in the device that processes the communications at a second transmission rate that is higher the first data transmission rate.
