Abstract: Systems and methods for controlling contactors to evenly distribute wear are disclosed herein. In one example, a method for an electric vehicle having a first charge inlet and a plurality of contactors electrically coupled to the first charge inlet includes, responsive to initiation of a charging event at the first charge inlet, closing at least a portion of contactors of the plurality of contactors according to a first sequence, the first sequence based on a respective accumulated wear of each contactor of the plurality of contactors.

Abstract: Systems and methods of controlling temperature in a cabin of an electric vehicle that has an HVAC system powered by a battery system and an auxiliary heating system. Upon determining, by a system controller, that a setpoint temperature is less than or equal to a sensed cabin temperature while operating in an HVAC electric heat state, an auxiliary heat state, or a maximum heat state, automatically transitioning to an off state from the HVAC electric heat state, the auxiliary heat state, or the maximum heat state.

Abstract: A geothermal system is used for obtaining heated heat transfer fluid, such as steam, via heat transfer with an underground reservoir of magma. The geothermal system includes a wellbore extending between a surface and into an underground chamber formed in a reservoir of magma. The chamber may be formed by injecting a fluid at an increased pressure into underground magma to form a cavity that acts as the underground chamber.

Abstract: An assembly includes a clip portion which includes a first flexible flange and a second flexible flange that each at least partially define a central retainer passage. A flexible hinge connects the clip portion to a structure. A tab is located adjacent an opposite end of the clip portion from the flexible hinge.

Abstract: Methods and systems for managing operation of a battery pack are described. The methods and systems may be applied to fully electric or hybrid vehicles. The methods and systems may open a circuit within a battery in response to an indication of degradation of the battery. In addition, the methods and systems may open a contactor of the battery that controls current flow out of and into the battery.

Abstract: A tined mole trap apparatus for catching moles of all sizes and preventing escape includes a pair of jaws comprising an outer jaw and an inner jaw. Each of the pair of jaws have a U-shaped upper portion and a pair of curved outer arms extending from the upper portion. A pair of crossbars is coupled between the pair of outer arms proximal the upper portion. A plurality of tines is coupled to the pair of crossbars. A pivot rod is coupled through the upper portion of each of the pair of jaws such that the inner jaw pivotably moves within the outer jaw between a clamped position and a spread position. A spring engages the pair of crossbars to force the pair of jaws towards the clamped position. A trigger plate is coupled to the crossbar of the inner jaw. A set rod maintains the pair of jaws in the spread position.

Abstract: A self-venting device includes a first component having an interior, a second component coupled to the first component so as to close the interior, and seal structure engaged between the first and second components in a sealed state so as to seal the interior from external agents. The seal structure includes a plurality of seal members, each having a resilient seal tip extending therefrom. The seal tips are constructed and arranged such that 1) when pressure inside the interior is equal to pressure outside of the device, the seal tips are compressed between the first and second components in the sealed state, and 2) when pressure in the interior is greater than the pressure outside of the device causing the second component to move away from the first component, the seal tips move to an unsealed state, permitting air to exit from the interior.

Abstract: A reconfigurable, modular ergonomic sit harness or saddle for use by linesmen, arborists, or the like includes a gender-specific back pad assembly that supports a number of removable, optional attachments allowing customization for user preference or job environment. Gender-specific angled wing portions of the back pad contain an armor layer and extra padding to protect the bony protrusions of both the male and female pelvis. A “one size fits all” approach includes a waistband having length adjustability over approximately a 3:1 range. Each component and sub-system of the sit harness is ergonomically designed to maximize comfort and minimize stresses on a user's body. The back pad features interchangeable lumbar support pads. Optional, removable features include a seat, an abdominal support, and a body harness for use with a fall restraint device. Interchangeable suspension bridges allow user attachment to a wide range of support systems.
