When the device determines that the signal for the first network has dropped below a threshold level of quality, it may enable access point mode for at least one of the paired devices by turning on a radio to establish a connection with a second network and thereby providing connectivity to the second network for the at least one of the paired devices. If multiple networks are available, the device may select an optimal network based on an assessment of one or more factors. | 09-18-2014 |

20140364068 | Switchable Antenna Elements for a Wireless Communications Device - A wireless communications device includes multiple switchable antenna elements that may be used to improve interfacing of the wireless communications device with other devices, such as for interfacing of an RFID-equipped mobile communications device with other RFID devices (e.g., to better ensure power delivery to and/or communication with such other RFID devices) and/or may be used to characterize various aspects of the environment around the wireless communications device, such as for proximity-based functionality. | 12-11-2014 |
20150015477 | Multi-Sensor Hand Detection - In one embodiment, a method includes receiving real-time sensor data from a number of sensors of different sensor types on a computing device. The real-time sensor data corresponds to a transition in a physical state of the computing device caused by a user of the computing device. The method also includes correlating the real-time sensor data from the number of sensors of different sensor types on the computing device; determining based on the correlation an intended imminent use of the computing device by the user; and automatically initiating based on the determination a pre-determined function of the computing device. | 01-15-2015 |
20150015488 | Isolating Mobile Device Electrode - In one embodiment, a method includes receiving real-time sensor data from multiple sensors located on multiple surfaces of a computing device; detecting a transition in the real-time sensor data from a steady state; and determining based on the detection an imminent use of the computing device. | 01-15-2015 |
20150019153 | Calibration of Grab Detection - In one embodiment, a method includes receiving real-time sensor data from N sensors on the computing device. The real-time sensor data corresponds to a transition in a physical state of the computing device caused by a user of the computing device. The method also includes applying a linear function to the real-time sensor data from each of the N sensors; determining a vector based on an N-tuple comprising the derivatives; comparing the vector with a pre-determined hyperplane with N−1 dimensions; and determining based on the comparison whether the transition is an event corresponding to any of one or more pre-determined imminent uses of the computing device by the user or a non-event not corresponding to any of the pre-determined imminent uses of the computing device by the user. | 01-15-2015 |
