An autonomous mobile device (AMD) builds up electrostatic charges from moving and generates heat from the operation of internal components. In addition to possible user discomfort, electrostatic discharges may damage sensors and electronics. Electrostatic charges are dissipated from the AMD using an electrostatic dissipation structure and conductive wheels. A conductive path between a chassis ground, the electrostatic dissipation structure, and the conductive wheels improves the dissipation of electrostatic charges. Electrostatic charges are also dissipated from components by mounting the components using conductive materials. Sensors may be affixed to a support structure that is affected by thermal expansion. Thermal expansion may distort precise positioning of sensors, reducing accuracy of sensor data. An elastomeric foam may be used to mount sensors to a support structure, allowing for thermal expansion without distorting the positioning of the sensors.

A damping force generation device for a vehicle includes a shock absorber including a cylinder and a piston. The shock absorber is coupled to a vehicle body, a wheel carrier, and the like at a rod part of the piston and the cylinder, respectively, and is configured to generate a damping force due to a flow resistance when oil passes through an orifice formed in the piston. Each of self-discharge type charge eliminators is fixed to a surface of a specific member being at least one of a component of the shock absorber or an auxiliary member connected to the component. The charge eliminator reduces positive electric charge that is charged to the specific member, to thereby reduce a charge amount of the oil.

The invention relates to a discharging device (10) for discharging electrostatic charges from a shaft (14), comprising a conductor arrangement having at least two bending-elastic conductors (24, 25) arranged on a holder (15) and made of a carbon-fiber arrangement, the holder having two holder legs (17, 18) arranged on a common pivot axis (12), each holder leg serving to accommodate a terminal section of a conductor and the holder legs being pivotable relative to each other in order for a holder angle (α) formed between the holder legs to be adjusted and the holder legs being lockable in a defined pivoted position.

The invention relates to an intermediate circuit discharge unit for an intermediate circuit discharge, in particular of a multi-level inverter, having a capacitor and a discharge circuit which is connected in parallel, where the discharge circuit has an active discharge branch with at least one first discharge element and a passive discharge branch with at least one second discharge element. The active discharge branch comprises a first control connection, and the passive discharge branch comprises a second control connection. The active discharge branch is coupled to the passive discharge branch via the first control connection in such a way that the active discharge branch can be controlled by the passive discharge branch, in particular a discharge via the active discharge branch can be activated or deactivated as required. The invention further relates to an electrical assembly, a vehicle, as well as a method.

A method of providing an electrical grounding point on an aluminum structural member of a motor vehicle. The member is hydro-formed to produce a closed cross-section, after which a hole surrounded by a flange is formed in a wall of the member. The flange is generally the shape of a truncated cone and extends toward an interior of the member. A self-tapping fastener having a grounding lead attached thereto is driven into the hole to cut threads into the flange and secure the grounding lead to the member. The self-tapping fastener allows the grounding connection to be achieved without any access to the hollow interior of the member as would otherwise be required.
