Abstract: A method for sensor provisioning in a wireless sensor network includes determining, at a gateway, that no neighboring gateway is present; in response to no neighboring gateway present, measuring signal strengths from a plurality of sensors; based on the measured signal strengths, identifying a sensor from the plurality of sensors to be paired with the gateway; and in response to identifying the sensor, pairing the gateway and the sensor to enable a secured connection between the gateway and the sensor.

Abstract: A method for cargo load detection in a container by a computing device, the method including projecting at least one light dot within an array of light dots towards a surface of the container; capturing an image of the at least one light dot on the surface of the container; and using the captured image to determine cargo loading within the container.

Abstract: The subject matter of the present invention relates generally to a vehicle that has axles with tires mounted thereon with at least one axle that is a lift axle, and more specifically, to a method that optimizes the effective tire rolling resistance by adjusting the load on the tires, resulting in an improvement in the fuel economy of the vehicle. According to one embodiment, the method takes into consideration the rolling resistance characteristics of the tires placed onto the axles of the vehicle and provides an algorithm for optimizing their rolling resistance by raising or lowering the lift axle.

Abstract: A method for updating communication parameters on a mobile device, the method including sending a communication from the mobile device to a server, the communication including a location of the mobile device; receiving at the mobile device, responsive to the communication, a new communication parameter; reconfiguring the mobile device with the new communication parameter; and sending a second communication from the mobile device to the server, the second communication using the new communication parameter.

Abstract: Based on a relationship between measurement data from at least one sensor and a baseline, a load status of a platform is determined. In response to the determined load status, such as determining that the platform is empty, the baseline is refined using a baseline estimator to produce a refined baseline that can be used to determine a further load status of the platform.

Abstract: A method at a sensor module within a sensor system for communicating with a gateway, the method including storing a timing profile for communications with the gateway; waking a radio core of the sensor module at a threshold time prior to a beacon signal being expected from the gateway; sampling a channel for the beacon signal at the radio core; if the beacon signal is detected: waking a processor on the sensor module; exchanging communication with the gateway; and powering down the processor and radio core upon completion of the exchanging communication.

Abstract: A system, methods, and apparatus for generating pattern recognition classifiers are disclosed. An example method includes identifying graphical objects within an image of a card object, for each identified graphical object: i) creating a bounding region encompassing the graphical object such that a border of the bounding region is located at a predetermined distance from segments of the graphical object, ii) determining pixels within the bounding region that correspond to the graphical object, iii) determining an origin of the graphical object based on an origin rule, iv) determining a text coordinate relative to the origin for each determined pixel, and v) determining a statistical probability that features are present within the graphical object, each of the features including at least one pixel having text coordinates and for each graphical object type, combining the statistical probabilities for each of the features of the identified graphical objects into a classifier data structure.

Abstract: In some examples, a plurality of instances of position data and associated accuracy metadata are acquired by a position sensor. A position of a device comprising the position sensor is determined based on combining the plurality of instances of the position data and the associated accuracy metadata.

Abstract: In some examples, a controller receives, from a sensor that is part of a device mounted on a moveable platform, measurement data. The controller detects, based on the measurement data, a change in transit motion status of the moveable platform. The controller triggers, in response to detecting the change in transit motion status of the moveable platform, a transition of the device from a first power state to a second, different power state.

Abstract: In some examples, a system receives, over a network, position data acquired by a position sensor of a device, and sensor data acquired by a further sensor of the device while the position sensor of the device is inactive, the sensor data from the further sensor indicating a direction of travel of the device. The system determines, using the sensor data acquired by the further sensor of the device, a heading and movement of the device relative to a position indicated by the position data, and updates a position of the device according to the determined heading and movement.

Abstract: Pneumatic tire for heavy duty vehicles having a crown portion comprising two working plies (114,116) and a breaker ply (120) radially outward of the carcass body ply wherein the breaker ply (120) comprises a plurality of breaker ply reinforcement elements (122) having a length L of no more than 155 mm, at an angle of 5°<60°.

Abstract: A rotary engine includes a housing and elliptical rotors mounted to rotor shafts for rotation within a chamber of the housing. A valve disk mounted to a rotor shaft includes a port passing between first and second sides. A valve plate includes a bore defining a cylindrical sidewall for rotationally receiving the valve disk. The valve disk includes a groove disposed in a wall, and includes a ring member disposed in the groove that contacts the sidewall of the bore when the valve disk is disposed in the bore. The apparatus may include multiple valve disks disposed in separate bores to operate as exhaust or intake valves. Circumferential channels may be included in the bore sidewalls within which the ring members are disposed.
