    Abstract: An electrical device that includes a ball grid array (BGA) component, comprising signal processing circuitry, a component mounting surface, and a BGA, which has solder balls that are spaced apart from each other on the component mounting surface. The electrical device also includes a plurality of electrical wires, each electrically coupled directly to a corresponding one of the solder balls of the BGA component. The electrical device further includes a wire fixation element, through which the plurality of electrical wires at least partially pass through. The wire fixation element is coupled to the plurality of electrical wires and configured to fix the electrical wires relative to each other so that the electrical wires do not move relative to each other.

    Abstract: Disclosed herein is an apparatus that comprises a printed circuit board having a first major surface, a second major surface opposite the first major surface, and a minor surface perpendicular to the first major surface and the second major surface. The apparatus also comprises an electronic component that comprises a ball grid array, having spaced apart solder balls, on a mounting surface of the electronic component. The electronic component is mounted to the minor surface of the printed circuit board such that the mounting surface is parallel to the minor surface and perpendicular to the first major surface and the second major surface. The solder balls of the ball grid array are electrically connected to both the first major surface and the second major surface of the printed circuit board.

    Abstract: Disclosed herein is a use-limiting connector for limiting use of an electrical tool. The use-limiting connector includes an electrical circuit, a plunger, movable between a first position and a second position, and a biasing member, configured to urge the plunger into the first position and configured to incrementally uncoil into respective torsional states as the plunger moves between the first position and the second position. With the plunger in the first position and the biasing member in a first one of the torsional states, the biasing member closes the electrical circuit. As the plunger moves from the first position to the second position, the plunger moves the biasing member to open the electrical circuit.

    Abstract: Examples of the present disclosure include an electrical connector. The electrical connector includes a plug. The plug includes a plug frame and plug ring-segment assemblies. The plug frame includes plug apertures. Each one of the plug ring-segment assemblies includes a plug ring-segment and a plurality of plug electrical contacts. The electrical connector further includes a receptacle. The receptacle includes a receptacle frame and receptacle ring-segment assemblies. The receptacle frame includes receptacle apertures. Each of the receptacle ring-segment assemblies includes a receptacle ring-segment and a plurality of receptacle electrical contacts. The plug is selectively connectable with the receptacle. When the plug is selectively connected to the receptacle, each one of at least some of the plug electrical contacts is in physical contact with a corresponding one of the receptacle electrical contacts.
