Abstract: A fully electric lift device includes a base assembly, a lift assembly, a platform assembly, tractive elements, an energy storage device, and a control system. The lift assembly is coupled with the base assembly and is driven by an electric linear actuator for a lifting function. The platform assembly is positioned at a top of the lift assembly and can be raised or lowered as the lift assembly performs the lifting function. The tractive elements are rotatably coupled with the base assembly and can be driven by an electric wheel motor to perform a driving function. The control system includes a controller that operates the electric wheel motor and the electric linear actuator to perform the driving function and the lifting function using power drawn from the energy storage device. The lift assembly and the tractive elements use only electrical energy to perform the lifting and driving functions.

Abstract: A shield assembly includes a closing structure configured to be disposed over an opening of an enclosure. The closing structure includes an inner surface configured to face an inside of the enclosure when the closing structure is closed and a finger bracket structure mounted on the inner surface, the finger bracket structure having a bracket and one or more finger gaskets coupled to the bracket. An electromagnetic interference (EMI) shielded gasket disposed along a portion of the opening of the enclosure shields an edge of the opening of the enclosure or a radio frequency (RF) fence bracket coupled to a frame disposed around the opening of the enclosure creates a narrow path between the frame and the closing structure, the narrow path attenuating RF signals passing through the narrow path and shielding an edge of the opening of the enclosure.

Abstract: A door assembly is described. The door assembly includes a door structure that is mounted over an opening of an enclosure. The door structure includes a body that includes a first surface and a second surface opposite to the first surface. The first surface may face an inside of the enclosure when the door structure is closed. The door structure includes a number of finger bracket structures mounted on the first surface.

The finger gaskets of the finger bracket structures may contact enclosure brackets mounted around an edge of the opening of the enclosure when the door structure is closed. A combination of the finger gaskets in contact with enclosure brackets may create an electromagnetic interference (EMI) shield at the edge of the opening of the enclosure.

Abstract: Systems and methods are described which focus on targeting and mobilizing specific populations of voters who are present in every voting district, including infrequent voting moderate voters in gerrymandered highly partisan districts. Based on population segmentation modeling and data analysis, desired voters are targeted. An individualized message is developed for each targeted voter, the message presenting the voting records of that voter's (i) close friends, (ii) colleagues, (iii) family members, and (iv) other social influencers in relation to the voter's own record. The individualized message can be delivered to each targeted individual via a variety of individually addressable communication means, including but not limited to direct mail, e-mail, and digital outreach including banner, display, mobile, online application, and social media on-line advertising. Such individualized messages can successfully mobilize large numbers of the target voters.
