Abstract: An electric machine is configured to be positioned within a wellbore. The electric machine enclosed within a housing isolates the electric machine from fluids within the wellbore. A first lubrication circuit includes a lubrication reservoir within the housing. The lubrication reservoir is fluidically connected to the electric machine. The first lubrication circuit is configured to provide lubrication to a bearing within the electric machine. A fluid rotor is configured to move or be moved by a fluid within the wellbore. A magnetic coupling couples the fluid rotor and a rotor of the electric machine to rotate in unison. A second lubrication circuit is configured to provide lubrication to a bearing supporting the fluid rotor.

Abstract: A computer implemented method, comprising: receiving a first audio signal; identifying one or more portions of the first audio signal as corresponding to one or more pre-determined text sequences; identifying one or more portions of the first audio signal as corresponding to one or more new text sequences; performing a voice authentication on a first portion of the first audio signal identified as corresponding to a first pre-determined text sequence and performing a separate voice authentication on a second portion of the first audio signal identified as corresponding to a new text sequence.

Abstract: An authentication method, comprising: obtaining a string; receiving an audio signal; performing speech recognition on the audio signal to extract text; and performing authentication of a user, the authentication comprising: comparing the extracted text and the string; and performing voice authentication of the user based on the audio signal.

Abstract: A wellhead bracing system for a subsea well includes a base plate assembly and a wellhead brace assembly. The base plate assembly comprises a top surface, a bottom surface, a base plate aperture, and a plurality of anchor holes. The wellhead brace assembly comprises a vertical plate assembly having a cylindrical shape, a horizontal plate assembly to which the vertical plate assembly is attached, and a vertical support assembly attached to an outer surface of the vertical plate assembly and attached to the top surface of the horizontal plate assembly. Horizontal plate holes of the horizontal plate assembly are configured to attach to studs on the top surface of the base plate to secure the wellhead brace assembly to the base plate assembly. The wellhead bracing system slides onto a wellhead of the subsea well and braces an exterior of the wellhead.

Abstract: The present disclosure generally relates to coatings and compositions comprising conductive polymers. The present disclosure also relates to thermally stable coatings and compositions comprising solution processable polyaniline conducting polymers and thermal stability agents, and to processes for preparing the coatings and compositions.

Abstract: Embodiments include a bar for a chain saw that is equipped with one or more oil channels that run along the length of the bar. Each oil channel receives oil at a first end, which exits the oil channel at an oil exit aperture at a second end of the channel. The oil exit aperture of one of the channels is positioned along the side of a bar groove, through which runs the saw chain, proximate to the cutting area of the bar to lubricate the saw chain just prior to the cutting area. A second channel may have an oil exit aperture proximate to the nose of the bar, to lubricate a sprocket wheel in the nose of the bar.

Abstract: A method for managing incoming voice calls, the method comprising: receiving audio of a voice call; determining whether the audio of the voice call is computer-generated; and terminating the voice call if it is determined that the audio of the voice call is computer-generated.

Abstract: A method for providing a user with secure access to an online account, the method comprising: receiving, from an institution hosting the user account, a message containing data to be used in obtaining access to the user account, issuing a request to a communication device of the user to provide a voice sample to be used in authenticating the user, receiving a voice sample from the user, performing voice authentication based on the voice sample, and in the event the voice authentication is successful, providing the user with the data to be used in obtaining access to the user account.

Abstract: A method of processing input data by a server, the method comprising: receiving speech data from a client device; extracting structured input data from the speech data; determining if the speech data corresponds to an authorised user; and if the speech data corresponds to an authorised user, executing a process based on the extracted structured input data.

Abstract: A method for managing incoming voice calls, the method comprising: receiving audio of a voice call; determining whether the audio of the voice call is computer-generated; and terminating the voice call if it is determined that the audio of the voice call is computer-generated.

Abstract: Methods and systems are provided for an electric turbocharger power lead. In one example, a system may include a conduit comprise at least one coolant jacket surrounding a passage housing a set of electric leads extending from an energy storage device to the electric turbocharger.

Abstract: Systems and methods for operating an internal combustion engine that includes an electric turbocharger are described. The systems and methods may operate the electric turbocharger in a motor mode or a generator mode. The electric turbocharger may be operated in a generator mode to reduce an amount of time to activate electric turbocharger in a motor mode.

Abstract: Methods and systems for operating an engine with an electrically driven compressor are described. In one example, a model in a controller determines one or more temperatures of the electrically driven compressor to establish a power output upper threshold that is not to be exceeded by the electrically driven compressor. Various actuators may be adjusted responsive to the power output upper threshold to reduce the possibility of electrically driven compressor degradation.

Abstract: Methods and systems are provided for an electric turbocharger. In one example, a method rotating a turbine of the electric turbocharger in a reverse direction, the turbine being mechanically coupled to a compressor via a shaft. The rotation of the turbine may be adjusted based on a cold-start and/or engine operating conditions outside of the cold-start.

Abstract: A magazine identifier is provided. The magazine identifier is an endless band having a front surface, a rear surface, a first side surface, a second side surface, an inner surface, an upper rim and a lower rim. The endless band is formed of a material with rubber elasticity. For example, the endless band may be made of natural rubber, synthetic rubber, silicone or any material with a similar elasticity to rubber. The endless band is placed over a magazine of a firearm to identify the type of ammunition carried within the magazine and the owner of the magazine.

Abstract: Systems and methods for operating an engine that includes an electrically driven compressor are disclosed. In one example, a vehicle operating mode is determined and speed of an electrically driven compressor is adjusted responsive to the vehicle operating mode so that an engine may supply torque sooner in response to an increasing torque command.
