Abstract: Technologies for determining a user's location include a mobile computing device to determine, based on sensed inertial characteristics of the device, a walking gait of a user. The walking gait is one of a first gait indicative of the user holding the g device to the user's side or a second gait indicative of the user swinging the device along the user's side. The device further detects that the user has taken a physical step based on the inertial characteristics and the determined walking gait of the user, and determines a raw directional heading of the device indicative of a direction of the physical step. The device determines an estimated location of the user based on the determined raw directional heading, an estimated step length, and the user's previous location.

Abstract: A sensor interface circuit enables signal reconstruction on data received from a sensor prior to sending the data to various sensor clients. Multiple sensor clients have different frequencies configured to receive sensor data. The sensor interface circuit performs signal reconstructions including data interpolation to generate interpolated data signal having frequencies corresponding to the different frequencies configured for the different sensor clients. Signal reconstruction can also include filtering the data. The sensor interface circuit sends the reconstructed data to the multiple clients in accordance with their different frequencies.

Abstract: In a method for protecting electronic data, a data processing system (20, 20A, 20B) uses (a) a master electrocardiogram (ECG) identifier (44) for an authorized user of the system and (b) a secret chip key (26) for the system to encrypt data in the system. Also, before allowing the encrypted data to be decrypted, the system collects an ECG reading for a current user of the system and uses (a) the collected ECG reading for the current user and (b) at least one predetermined ECG identifier (EID) vector for the authorized user to determine whether the current user is the authorized user. In response to determining that the current user is the authorized user, the system uses the master ECG identifier (44) for the authorized user and the secret chip key (26) for the system to decrypt the data.

Abstract: Technologies for determining a user's location by a mobile computing device include detecting, based on sensed inertial characteristics of the mobile computing device, that a user of the mobile computing device has taken a physical step in a direction. The mobile computing device determines a directional heading of the mobile computing device in the direction and a variation of an orientation of the mobile computing device relative to a previous orientation of the mobile computing device at a previous physical step of the user based on the sensed inertial characteristics. The mobile computing device further applies a Kalman filter to determine a heading of the user based on the determined directional heading of the mobile computing device and the variation of the orientation and determines an estimated location of the user based on the user's determined heading, an estimated step length of the user, and a previous location of the user at the previous physical step.

Abstract: Systems and methods may provide for a fitness sensor that is located and operates in a sensor hub. The fitness sensor may link to a Bluetooth link controller, a communications hub and numerous environmental and physical sensors in a platform that is conducive to low power utilization. Awakening a host processor only when valid content-oriented sensor data is available may assist to reduce a footprint of power consumption and time spent in computer processing fitness models.

Abstract: Systems and methods may provide for obtaining first sensor data associated with a gyroscope and obtaining second sensor data associated with a magnetometer. Additionally, the first sensor data, the second sensor data and an extended Kalman filter may be used to calibrate the magnetometer. In one example, a sampling rate of the magnetometer is increased before obtaining the second sensor data and the sampling rate of the magnetometer is decreased after calibration of the magnetometer.

Abstract: A system includes a processor in a lid portion of a computing device. The processor is communicatively coupled to a plurality of input/output (I/O) devices according to a plurality of I/O communication protocols via a first number of wires. The system includes a first memory coupled to the processor to store instructions that can be executed by the processor and cause the processor to receive, from a first I/O device of the plurality of I/O devices, a first message according to a first I/O communication protocol of the plurality of I/O communication protocols, convert the first message to a second message according to a host communication protocol, and send the second message over a bus containing a second number of wires traversing a hinge movably coupling the lid portion to a base portion of the computing device. The second number of wires is less than the first number of wires.
