  • Patent number: 11921837
    Abstract: Features are disclosed for a dynamic security seal indicating a security of an application. A computing device can receive a request to implement a dynamic security seal for an application. The computing device can validate a relationship between an entity and the application and between an image and the application. Based on validating these relationships, the computing device can generate a dynamic security seal. When implemented, the dynamic security seal may display a plurality of faces. A face of the plurality of faces may be the image. The dynamic security seal can sequentially display the plurality of faces based on various criteria.

  • Publication number: 20240069860
    Abstract: A voice-controlled question answering system that is capable of answering questions using both a knowledge base and a search engine. The knowledge base is used to answer questions when answers to those questions are contained in the knowledge base. If an answer using the knowledge base is unavailable, and if the question is suitable for answering using an unstructured search approach, the system may obtain an answer using a search engine. The search engine results may be processed to obtain an answer to the question suitable for output using a voice user interface.

  • Patent number: 11186417
    Abstract: A box with a lid having first and second opposed pairs of downwardly projecting legs which partially overlie the sides of the box to close the same. The length of the first pair of downwardly projecting legs is less than the length of the second pair of downwardly projecting legs. A generally horizontal ledge is formed in each side of the box with the ledges of two opposed sides of the box located at one level below the lid and those of the other opposed sides at a different level below the lid. In use, the first and second pairs of legs can either be supported on either one or the other pair of opposed ledges to vary the height of the lid above ground level. Also, the lid can be removed from the box to define a stool or support surface.

  • Patent number: 9869227
    Abstract: A system for determining at least one property of a fluid and ensuring measuring surfaces of the system in contact with the fluid remain free of contaminants, includes a housing within which at least one measuring surface is located. The fluid to be measured flows through the housing and contacts the measuring surface. A signal generating device operably associated with the surface provides signals indicative of the at least one fluid property. A transducer is operably associated with the housing and causes agitation of the fluid flowing through the housing so that the measuring surface can be cleaned even during fluid measurement.

  • Patent number: 9465000
    Abstract: A system and method for measuring at least one property of a fluid includes a housing for receiving the fluid, a first and second spaced electrodes positioned in the housing, and an impedance modifier positioned between the first and second electrodes that changes an electrical impedance of the fluid between the electrodes. Electronic circuitry generates different waveform voltages across the electrodes and the fluid, monitors an output thereof to thereby obtain data related to impedance of the fluid for each waveform voltage; and combines data related to the outputs to create a unique identification signature for the fluid. Once signatures for known fluids have been created, they can be compared to a generated signature of an unknown fluid to identify the unknown fluid.

  • Publication number: 20120328457
    Abstract: An unlimited stroke drive method for pumping fluid from an oil well in which the well has a tubing string extending from the earth's surface down to a fluid producing formation. The method includes the steps of positioning a pump barrel within the tubing, an upper end of the pump barrel having communication through a standing valve with the interior of the tubing string, vertically reciprocating a length of flexible cable within the tubing string to vertically reciprocate a plunger within the pump barrel to allow a lower portion to quickly fill with fluid from the producing formation and then to a downward position in which fluid within the pump barrel lower portion is transferred through a traveling valve to an area within the pump barrel above the plunger to move formation fluid from within the pump barrel to the interior of the tubing and thence to the earth's surface.

  • Publication number: 20120315154
    Abstract: A system and method for pumping an underground drip includes a pump barrel housing with a plunger and an elongated stroke actuator cylinder sealed to the pump barrel that vertically reciprocates the plunger. The pump barrel and plunger are preferably vented to avoid vacuum lock during pumping. The plunger pumps the fluid located in the drip upwardly to a low pressure tank or a pressurized surface vessel. A ball valve may be screwed onto the siphon line to allow for insertion and removal of the pump barrel and seals the siphon line if the pump is removed. A stuffing box seals the pump barrel to the upper end of the siphon line to prevent air from entering the system. The stuffing box also allows the pump depth to be easily adjustable by sliding the pump in until the pump tags bottom and then tightening at any point needed.

  • Publication number: 20120114510
    Abstract: A reciprocated pump positioned at the lower end of a string of tubing in a bore hole that provides a passageway for moving formation fluid to the earth's surface, including a pump barrel supported in communication with the tubing and a standing valve at the lower end thereof providing a first passageway through which formation fluid flows into the pump barrel, the pump barrel having an intermediate vent port providing a second entry passageway, and a tubular plunger reciprocated within the barrel and having an upper and a lower portion with a plurality of non-metallic seal rings separated by metallic spacers received on the plunger upper portion and configured to support a column of formation fluid within the tubing to substantially isolate the portion of the barrel below the non-metallic seal rings from the tubing pressure to thereby allow formation fluid to move into the pump barrel.
