Abstract: A safety valve includes a housing having a bore, a flow tube, and a valve closure member. The flow tube resides in the bore, is configured to move telescopically within the bore, and is adapted to shift the valve closure member between a closed position and an open position. The safety valve also includes an annular section between an inner surface of the housing and an outer surface of the flow tube, and means for preventing fluid flowing through the bore from entering the annular section.

Abstract: A camera for a vehicle includes an image sensor and processing logic. The image sensor captures event images based on one or more messages generated by the vehicle communication bus.

Abstract: A technique facilitates improved sealing with respect to safety valve pistons so as to improve reliable safety valve operation. According to an embodiment, a safety valve piston seal assembly is positioned about a safety valve piston and comprises components which divert a load path to the safety valve piston rather than to susceptible components of the seal assembly. For example, the seal assembly may comprise a load ring and spacers to energize a V-ring when pressure is applied to a metal spring energized (MSE) seal. However, the components are arranged so the load path is diverted to the safety valve piston when pressure occurs behind the V-ring instead of allowing the loading to act against the MSE seal.

Abstract: The present disclosure provides a combined Pulsed Electromagnetic Field (PEMF) therapy and Photobiomodulation (PBM) therapeutic device in the form of a flexible wearable that can be secured to a user's body part to apply targeted radiation to a desired area. The frequencies and pulse patterns of both types of radiation are controlled by a single controller of the device which can switch between a number of pre-set sequences and patterns. The device is wirelessly enabled to allow control via an external user device.

Abstract: Methods of the disclosure include a camera for a vehicle capturing event images in response to one or more messages generated by a vehicle communication bus of the vehicle. Event notification images may be wirelessly transmitted to a user device.

Abstract: A jamming radio signal is selectively outputted based on an access signal. The jamming radio signal is configured to prevent an interrogation signal of a vehicle to complete an authentication of a vehicle key of the vehicle.

Abstract: A downhole tool includes an upper flow tube connected to a lower flow tube, an upper flapper sub-assembly including an upper flapper, and a lower flapper sub-assembly including a lower flapper. The upper and lower flapper sub-assemblies are installed with respect to the upper and lower flow tubes in an “O” configuration such that the upper and lower flapper sub-assemblies are in a closed position. The upper and lower flapper sub-assemblies are capable of being independently actuated. The upper and lower flow tubes remain stationary when the upper flapper sub-assembly or the lower flapper sub-assembly is actuated from the closed position to an open position.

Abstract: A jamming radio signal is outputted to interfere with an interrogation signal emitted by a vehicle for verifying a tag of a vehicle key that provides access to the vehicle. An access signal including access data is received. The output of the jamming radio signal is halted, at least temporarily, when the access data matches an access code so that the tag of the vehicle key can be authenticated.

Abstract: A propagation tray for growing a plurality of plug plants in bounded transplantable growing media has two spaced apart aperture plates. The plug plants are held loosely in the apertures in a top plate while retained at the apertures in the bottom plate over air cells associated with and under the apertures in the bottom plate. The air cells provide a volume into which roots from the plug plant may grow, and the air cells have at least one port for drainage and/or ventilation and toward which roots are guided to be air pruned. The propagation tray maximizes air flow around the plug for air pruning of roots, while minimizing contact of the plug with the structures on the tray to reduce the formation of root defects.

Abstract: Automatic extraction and application of conditional tasks from content is provided. A conditional task system includes a classifier that is trained and used to identify conditional tasks and to learn appropriate times and methods to engage a user for reminding the user about conditional tasks. The conditional task system includes components for enabling an automated detection of a conditional task, extracting of attributes that characterize a condition associated with the task, using information about the condition to determine how to monitor for satisfaction of the condition, determining when and how to engage the user about the task, and notifying the user at an appropriate time and using an appropriate method when the condition is satisfied.
