Abstract: A data hub of a home automation system is powered by a power supply of at least one powered device of the home automation system that is connected to the data hub. By providing power to the data hub from the one of the devices that are connected to it, the need for a separate power source is eliminated. A method for powering a data hub of a home-automation system without bus power includes connecting at least two independently powered devices to device ports of the data hub. When the powered devices are connected to the ports, a voltage is detected by an internal power regulation, protection and distribution unit of the hub and disconnects bus power. A system for powering the data hub includes configuring the hub to receive power by devices connected thereto. When the hub receives power from the powered device, bus power is disconnected.

Abstract: An apparatus includes: a main body including an interior configured to receive an electrical apparatus, the main body including at least one opening to the interior; and a door configured to overlap the at least one opening to the interior in a first position and to not overlap the at least one opening to the interior in a second position. The apparatus also includes a mounting assembly that includes: a first articulating connection attached to the main body; a second articulating connection attached to the moveable door; and a link between the first articulating connection and the second articulating connection. The mounting assembly is configured to permit the door to move laterally relative to the main body and to rotate about the second articulating connection to transition from the first position and the second position.

Abstract: A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.

Abstract: A downhole tool includes a housing and a housing chamber. The housing chamber is separated from a fluid chamber by a seal. The seal maintains a pressure differential between the housing chamber and the fluid chamber. A pressure adjuster between the housing chamber and the fluid chamber maintains the pressure differential below a maximum pressure differential.

Abstract: A magnetic electrical switch apparatus includes: a switch assembly that includes: a switch body housing including a stationary contact; a shaft configured to move relative to the switch body housing, the shaft including: a moveable contact; and a first magnet; and a movable support member including a second magnet. The moveable contact and the first magnet are configured to move with the shaft. Moving the movable support member moves the second magnet relative to the first magnet, and a magnetic interaction between the second magnet and the first magnet moves the moveable contact relative to the stationary contact to thereby change a state of the switch assembly.

Abstract: A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.

Abstract: A method and apparatus is disclosed whereby the context of user activity can be used to tailor the ambient information system. The method and apparatus use both short-term context such as recent activity and long-term context such as historical patterns to highlight specific content on channels or widgets that are likely to be of most immediate interest to the user. This contextual information provided by the framework can also be used to make intelligent decisions about how to tailor the user experience after a user has interacted with the item in question. Additionally, context information accumulated on one device such as a mobile phone can be broadcasted to other devices to influence the ambient information display application on a second device such as a desktop based on enabling remote access to the local context repository.

Abstract: Rotary steerable drilling apparatus and methods utilizing apparatus comprising a shaft, a multi-angle strike ring axially repositionable along the shaft, an articulated member coupled to the shaft, and a steering member carried by the articulated member. An actuator is operable to maintain an angular offset of the articulated member relative to the shaft by maintaining azimuthally-dependent contact between the multi-angle strike ring and the steering member.

Abstract: A technique facilitates steering during, for example, a borehole drilling operation. The technique employs a drill string comprising a drill bit and a steering tool for controlling the trajectory of a borehole formed by rotating the drill bit. The steering tool includes a main body and a steering sleeve pivotably mounted to the main body by a joint located to enable pushing contact via the steering sleeve against a surrounding borehole wall at a location between the joint and the drill bit. The steering sleeve is selectively pivoted by a plurality of actuators disposed between the main body and the steering sleeve.

A steerable system is designed with a main shaft coupled to a drill bit shaft by a universal joint to provide steering functionality. A sensor system is mounted on the steerable system and comprises at least one sensor positioned to measure desired parameters, such as weight on bit and/or torque on bit parameters during drilling.

Abstract: A technique facilitates the drilling of deviated wellbores. A steerable drilling system is formed with a pair of components pivotably mounted with respect to each other. A removable strike ring is mounted to one of the steerable drilling system components and is positioned to engage a corresponding strike ring in a manner which limits the maximum pivot angle between the steerable drilling system components. By interchanging the removable strike ring with other removable strike rings, the maximum pivot angle can be adjusted in the field to accommodate drilling of a wider variety of deviated wellbores.
