Abstract: A method and system for a non-intrusive parallel surface calibration for gyroscopes in a mobile device are described. In a mobile device having a gyroscope, multiple rotation matrices can be determined based on readings from the gyroscope. Each of these rotation matrices corresponds to a chain of rotations that occur when the mobile device is picked up from a surface and later placed down on any substantially parallel surface. In some instances, three or more rotation matrices can be determined. Calibration parameters can be computed from the rotation matrices and can be used to adjust subsequent readings from the gyroscope. An eigenvector can be determined for each of the rotation matrices and those eigenvectors can be used to obtain the calibration parameters through an optimization process. The gyroscope calibration can be triggered by a change in the temperature of the mobile device.

Abstract: Aspects of the present disclosure relate generally to indoor localization, for example, where GPS or other localization signals are unavailable. More specifically, aspects relate to using inertial navigation systems (132) such as accelerometers (136) and gyroscopes (134) to aid in the determination of the location of a user. Certain devices such as MEMS gyroscopes found in handheld client devices (104) should be calibrated to ensure accurate location information is obtained. In one aspect, a Vibration Energy Model process (FIG. 4B) is performed on shaking energy generated as a user walks with a mobile device to detect the direction the user is walking in. This information may be used as part of a signal fusion system to perform accurate indoor localization of the user, such as to provide enhanced maps and location services to the user.

Abstract: Systems and methods for robust perceptual color identification are disclosed. The methods include a multilevel analysis (120) for determining the robust perceptual color of an object based on observed colors. This multilevel analysis can include a pixel level (120), a frame level (145), and/or a sequence level (150). The determination may make use of color drift matrices (130) and trained functions such as statistical probability functions (160). The color drift tables and function training are based on training data generated by observing objects of known robust perceptual color in a variety of circumstances. Embodiments of the invention are applicable to the identification and tracking of objects, for example, in a surveillance video system (100).

Abstract: A set of techniques are disclosed for organizing an electronic memory to increase the effective decoding speed while being able to randomly address storage locations in the memory. The memory typically contains a memory array (41 or 51) and address circuitry (40 or 50). In one memory-organization technique, the address circuitry contains a group of decoding segments (501-50M) arranged in series. Each decoding segment partially decodes an input memory address. In another memory-organization technique, the address circuitry contains a plurality of decoding segments (401 and 402) arranged in parallel, each decoding segment sequentially decoding different ones of the input memory addresses than each other decoding segment. A variation of the parallel memory-organization technique can be used with off-the-shelf memories.

Abstract: Aspects of the present disclosure provide techniques for constructing a scalable model of an indoor space using crowd-sourced inertial navigation system (INS) signals from mobile devices. By tracking INS signals from a number of participating users, the user's trajectories can be estimated as they move their mobile devices indoors. The estimated trajectories can be scored against similar routes taken by other users. Routes with the highest scores are then laid out over a map of the indoor space to identify areas most often traveled to and from landmarks and distances between the landmarks.
