Abstract: A trailer landing gear drive shaft rotating device for operating legs of a trailer landing gear assembly includes first and second couplers, which are attached to first and second ends of a rod, respectively. The first coupler is selectively couplable to a drive shaft of a trailer landing gear assembly so that the rod is reversibly pivotal between stowed and interim configurations, wherein the rod hangs from the drive and is substantially colinear with, and slidable relative to, the drive shaft, respectively. A terminal segment of the drive shaft is slidable into a first recess, which extends into the first end, as the rod is slid from the interim configuration to an operable configuration. The second coupler can engage a rotary tool, which then is positioned to impart a rotary force to the drive shaft to selectively raise and lower one or more legs of the trailer landing gear assembly.

The connector being coupled to the second connector of the mobile computing device retains a position of the mobile computing device relative to the base.

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: Aspects of the technology provide a multi-purpose card reader configured for use with a mobile electronic device (e.g., a mobile host), such as a smart phone or tablet computer. In certain aspects, the card reader is integrated into a case for enclosing the mobile electronic device and configured for reading financial information from a payment card to facilitate a financial transaction between a buyer and a merchant. To facilitate operability of the card reader, the case can include multiple card slots, such as a swipe-slot (e.g., for receiving a magnetic stripe payment card), and a dip-slot (e.g., for use in receiving an IC type payment card).

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: 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.
