Abstract: A valve component utilized in a fluid end assembly of a reciprocating pump may contain a multi-piece construction. The valve component may include a valve body portion, a leg assembly portion, a sealing element, and an insert at least partially captured between the valve body portion and the leg assembly portion. The insert may be constructed from a carbide or a ceramic material, and, when the valve component is fully assembled, may be compressed between the valve body portion and the leg assembly portion. The insert may at least partially form the strike surface of the valve component. The valve body portion and the leg assembly portion may both be constructed from a metallic material, and the valve body portion may define a sealing seat. The sealing element may be constructed from an elastomeric material that may be pre-formed and then compression molded onto the seat of the valve body.

Abstract: A joint assembly couples a linear actuator to a body. The joint assembly includes a first body having a first surface and a second body having a second surface. The first body is coupled with the second body. The first surface and the second surface have arcuate configurations that are complementary to facilitate rotation of the first body relative to the second body about a first axis, a second axis, orthogonal to the first axis, and a third axis, orthogonal to both the first axis and the second axis. The joint assembly also includes a damper disposed between the first body and the second body and configured to dampen translational motion of the first body toward the second body in response to movement of the linear actuator relative to the body.

Abstract: In a method or system in which an imaging element views navigation elements for e.g. navigation, the navigating elements may not be positioned optimally. Positions may exist in which the same angles exist from the imaging element to the same or similar navigating elements, whereby the positions are not unique. Navigation elements may then be repositioned, added or removed to make the positions unique.

Abstract: A method for evaluating performance of an operator of a service vehicle, such as a cleaning vehicle, is disclosed. While the operator operates the service vehicle, sensor readings related to the operation of the service vehicle are collected, by means of one or more sensors of the service vehicle. The collected sensor readings are compared to a set of predefined corresponding sensor values reflecting operation of the service vehicle, and performance of the operator is evaluated based on the comparison.

Abstract: The present disclosure provides a magnetic system within a case for an electronic accessory. The case may include a housing portion and a lid coupled to the housing portion. Within the housing portion may be a housing magnet. The housing magnet may be oriented such that the magnetic field of the housing magnet is oriented transverse to a longitudinal axis of the case. The housing magnet may have a size and strength to magnetically couple the electronic accessory within a cavity of the housing. A hinge magnet may be located along an axis of rotation of the lid with respect to the housing. The hinge magnet and housing magnet may magnetically interact to form a bistable magnetic hinge. Thus, the one housing magnet may be large enough and have a strong enough magnetic field to perform various functions.

Abstract: A combustion system configured to receive fuel from a plurality of fuel sources, wherein the combustion system includes a burner, a shutter, a fuel selector, and an electronic controller configured to receive an indication of a selected fuel type from the fuel selector and output instructions for the shutter to adjust to a shutter position associated with the selected fuel type, the shutter position being configured to provide a predetermined supply of air to thereby effect an air-to-fuel ratio associated with combustion of the selected fuel type.

Abstract: A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

Abstract: Systems and methods for monitoring and management of an electronic device are discussed here. An authentication request is received from a user for access to an electronically secured compartment of an electronic device. Authentication data is obtained from the user. An authentication request that includes a device identifier for the electronically secured compartment and the authentication data is transmitted to a cloud-based authentication service. Access to the electronically secured compartment is provided upon receipt of an indication of an association between the user and the electronically secured compartment from the cloud-based service provider.

Abstract: A wearable audio device sized to fit within an ear of an user comprises an outer housing; a circuit board positioned within the outer housing; a battery having an anode and a cathode, the battery being connected to the circuit board; a speaker adjacent the battery; and an electromagnetic interference (“EMI”) shield tab coupled to the anode. The EMI shield tab may be configured to shield the speaker from EMI generated by the circuit board and to provide an electrical interconnection to the anode.
