A retinal projection display system includes a light source for projecting an image, a scanning mirror having a field of view larger than the image, and a reflective surface on which the image is projected, wherein the reflective surface is larger than the image. The scanning mirror projects the image onto a viewable region of the reflective surface such that the image is projected into a retina of a user.

Retinal projection display system

The subject matter disclosed herein relates to determining a background location of a mobile device using one or more signal metrics.

On demand positioning

A retinal projection display system includes at least one visible light source for projecting a visible light image, an infrared light source for projecting infrared light, a scanning mirror having a field of view larger than the visible light image, a reflective surface on which the visible light image is projected and on which the infrared light is reflected at least partially towards an eye of a user, wherein the reflective surface is larger than the visible light image, at least one infrared photodetector for receiving reflected infrared light that reflects off of the eye of the user, and a hardware computation module comprising a processor and a memory, the hardware computation module configured to determine a gaze direction of the user based at least in part on the reflected infrared light.

In a method for determining vibrations generated by a device, first vibration measurements are received from a first accelerometer coupled to the device, the first vibration measurements comprising a first device vibration contribution and a first environmental vibration contribution, wherein the device is located within an environment comprising a plurality of devices capable of generating vibrations. Second vibration measurements are received from a second accelerometer located within the environment and not connected to the device, the second vibration measurements comprising a second device vibration contribution and a second environmental vibration contribution. The first vibration measurements and the second vibration measurements are compared. Based on the comparing, the first device vibration contribution is estimated. An operational condition of the device is determined based on the estimating, wherein the operational condition is indicative of device performance that may be impacted by device vibration contributions.

Method and system for determining vibrations generated by a device

Described herein are methods and systems for configuring a motion sensor assembly to compensate for a temperature gradient. First and second sensors of the same type are arranged as opposing pairs with respect to a first axis that may be defined by a temperature gradient caused by at least one thermal element. Combining the output measurements of the first sensor and the second sensor allows effects of the temperature gradient on sensor measurements of the first sensor and the second sensor to be compensated.

Method and system for sensor configuration

In a method of associating a single entity with multiple electronic devices, a server accesses user data collected via internet communications with a plurality of electronic devices. Each item of user data includes a location signature and a unique identifier. The server determines an intersection of location between two electronic devices of the plurality of electronic devices based on the user data accessed from the two electronic devices. The user data is accessed from a first of the two electronic devices has a first unique identifier that is different than a second unique identifier of the user data accessed from a second of the two electronic devices. Based on the intersection of location, a single entity is associated with both the first unique identifier and the second unique identifier.

Associating a single entity with multiple electronic devices

An apparatus and method are disclosed for user and moving vehicle detection in which sensor data for a portable device is processed to determine whether the portable device is in a moving vehicle. Following a determination the portable device is in a moving vehicle, the sensor data is to characterize an association between the user and the portable device to determine whether the portable device is connected to the user. If the user is connected to the portable device, it is then determined if the portable device is being held in hand. If the portable device is held in hand, it is then determined if the user is operating the moving vehicle. Output from an image sensor of the portable device may be used in determining if the user is the operator.

Method and apparatus for user and moving vehicle detection

Systems and methods are disclosed for determining location information for a portable device by identifying interactions indicating proximity between the user and a plurality of items. Each item may be associated with a known location to establish anchor points such that a route traversed by the portable device may be generated from the established anchor points and motion sensor data output by the portable device.

Systems and methods for determining a route traversed by a portable device

A sensor is compensated by selectively activating a temperature element to drive temperature within the thermal envelope encompassing the sensor towards an operating temperature and applying a compensation to output of the sensor based at least in part on the operating temperature. The initial ambient temperature is estimated and the operating temperature is selected from a set of predetermined temperatures based on the estimate. The current ambient temperature is estimated and a new operating temperature selected when the current ambient temperature is within a threshold of the operating temperature. Correspondingly, the temperature element is selectively activated to drive temperature within the thermal envelope towards the new operating temperature and an appropriate compensation is applied to the sensor output.

Systems and methods for thermally controlling sensors

Systems and methods are disclosed for refining a coarse location determination by detecting patterns of motion sensor data that may be associated with predetermined locations. One or more geofeatures may be identified that cause a mobile device associated with a user to detect a distinguishable pattern of sensor data when the user interacts with the object. Accordingly, a coarse location may be refined using information associated with the geofeature, such as the location of the geofeature.

Systems and methods for determining position using a geofeature

Systems and methods are disclosed for providing a plurality of navigation solutions using a portable sensor device associated with a user. Motion sensor data may be used to derive a first navigation solution using the obtained sensor data under a first set of processing conditions navigation solution and to derive at least a second navigation solution using the sensor data under a second set of processing conditions, wherein the second navigation solution is refined as compared to the first navigation solution. As such, the second navigation solution may represent a more accurate or more complete solution, with the first navigation solution may represent a reduced expenditure of resources. The system includes the portable sensor device and optionally may include an auxiliary device associated with the user and/or remote processing resources. The functions associated with deriving the first and second navigation solutions may be performed by any one or any combination of the portable sensor device, the auxiliary device and/or the remote processing resources.

Method and system for providing a plurality of navigation solutions

A system includes a wearable device connected to a user and a smart media in remote communication with the wearable device. The wearable device is operable to track movement of the user and transmit the track movement information to the smart media. The smart media is operable to receive the track movement information and to use the received track movement information in an independent application.
