Abstract: In some examples, method includes positioning a first electronic device in a target orientation with respect to a second electronic device and moving the first and second electronic devices in at least two degrees of freedom of motion while the first electronic device is maintained in the target orientation with respect to the second electronic device. The method may also include operating the first electronic device while the first and second electronic devices share a secure communication connection that is based on a first numerical value and a second numerical value. The first numerical value may be based on data that describes the movement of the first electronic device while maintained in the target orientation, and the second numerical value may be based on data that describes the movement of the second electronic device while the first electronic device is maintained in the target orientation.

Abstract: Technologies are generally described to communicatively couple an optical fiber to an optical element using a polymer layer. An optical fiber may be coupled to an optical element, such as an optical waveguide or another optical fiber, using a layer of rewritable photorefractive polymer positioned between the optical fiber and the optical element. Light from a light source may be applied to the optical fiber to initiate a transient photorefractive effect in the polymer layer facilitating corrections of misalignment. A path of high refractive index may be formed in the polymer layer, where the path of high refractive index communicatively couples the optical fiber to the optical element reducing alignment concerns and increasing alignment tolerances of optical elements. In some examples, the path of high refractive index may be re-established by rewriting the polymer layer through another application of light from the light source if the communicative coupling is disrupted.

Abstract: In some examples, a method of sensor degradation compensation is described. The method may include generating first characterization data for calibration of a first sensor, from amongst multiple sensors that include the first sensor and at least a second sensor, based on first sensor data generated by the first sensor. The method may further include providing the first characterization data to be pushed to the second sensor. The second sensor may be configured to be calibrated with the first characterization data. The method may also include collecting second sensor data generated by the first sensor and generating second characterization data based on the second sensor data after the first characterization data is provided. The method may further include providing the second characterization data to be pushed to the second sensor. The second sensor may be configured to be recalibrated with the second characterization data.

Abstract: In some examples, a device may include an orientation sensor, a device sensor, a sensor regime storage unit, an analysis module, and a device output module. The orientation sensor may generate orientation data indicative of a physical state of the device. The device sensor may generate device data. The sensor regime storage unit may store sensor regimes that process the generated device data while in the physical state. The analysis module may be coupled to the orientation sensor and the sensor regime storage unit, and may determine the physical state based on the generated orientation data and select a particular sensor regime based on the determined physical state. The device output module may be coupled to the analysis module and the device sensor, and may receive the particular sensor regime and process the device data using the particular sensor regime. The device may be implemented as a wearable sensor device.
