Motor control centers have units or buckets with an operator mechanism with a retractable power stab assembly and one or more sliding shutters that controllably block access to a stab isolation port based on position of the operator disconnect handle using an attached shutter cam that slides the shutter right and left.

The present invention is to perform position estimation in relation to a vehicle and a key module by using an ultra-wideband (UWB) and, specifically, relates to a method and system for precise position estimation for a vehicle, whereby position can be estimated, with effects minimized that result from the type of the vehicle and the quality of exterior metal of the vehicle.

The method for precise position estimation for a vehicle over a UWB comprises the steps of: receiving, by an LIN transceiver, a position estimation-related signal delivered from an internal part of a vehicle, and transmitting the signal to a UWB transceiver to start the position estimation; the control unit measuring a predetermined number of times reception signal delays occurring in relation to a UWB tag, while turning on or off the switch of each of M antennas at predetermined time intervals; determining antennas at which the value of a corresponding reception signal delay measured the predetermined number of times is lower than a preset threshold; measuring the distances between the determined antennas and the distances between each of the antennas and the UWB tag; determining position angles with respect to the UWB tag by using a two-way ranging (TWR) positioning method on the basis of the distances between the antennas and the distances between each of the antennas and the UWB tag; measuring the distances between the UWB tag and UWB anchors measured using a triangulation method according to the M anchors and UWB tag; and estimating the position of the UWB tag on the basis of the position angles with respect to the UWB tag and the distances between the N UWB anchors and the UWB tag.

A multipurpose relocatable structure includes a floor system, a framework secured to the floor system, and walls coupled to the framework. The walls include a number of panels that are secured along adjacent vertical edges. The multipurpose relocatable structure may include a preconfigured interior, one or more doors having an emergency escape hatch, a protected electrical connector, an environmental control system that is configurable between operational and transport configurations, and lifting corners having securement apertures.

A system for supplying power to at least one power distribution and data hub using a portable battery pack including a battery enclosed by a wearable and replaceable pouch or skin is disclosed, wherein the pouch or skin can be provided in different colors and/or patterns. Further, the pouch or skin can be MOLLE-compatible. The battery comprises a battery element housed between a battery cover and a back plate, wherein the battery element, battery cover, and back plate have a slight curvature or contour. Further, the battery comprises flexible leads.

Circuit breakers with a housing with a line side and a load side and an electronically controlled lock-out lock member coupled to the housing configured to electronically controllably travel between a first position and a second position. In the second position, the lock member is in a lock-out position and prevents the handle from moving to an ON position associated with electrical current conduction and in the first position the lock member is translated to a position that allows the handle to move to the ON position.
