Abstract: An illumination device for a firearm may include a housing supporting multiple lamps. A switch actuator of the device is rotationally coupled to a rear end of the housing. A cam is coupled to the switch actuator, such that the cam rotates with the actuator, the cam having a first end including a magnet and a second end having a shaped cam surface configured to interface with a cam follower. The actuator and the cam are biased toward a neutral position. Selective rotation of the cam causes a magnet of the cam to operate one or more magnetic switches. The cam is transitionable between a plurality of discrete positions, e.g., including a pair of toggle positions in the first rotational direction from the neutral position, and a pair of momentary positions disposed on the cam in the second rotational direction from the neutral position.

Abstract: A system for refilling a multi-chamber implantable infusion device is presented. The infusion device has a refill chamber which is accessible through an external septum of a refill port. The refill chamber is divided by an inner septum into an upper reservoir and a lower reservoir. The lower refill chamber is refilled with lower reservoir needles having a needle opening axially placed to align with the lower reservoir. The upper reservoir is refilled with an upper reservoir needle having an opening aligned with the upper reservoir. Magnetic portions are provided in the needles to localize and identify the needle. A processor within the infusion device is connected to magnetic field sensors which sense magnetic portions of the needle and recognize information encoded magnetically within the needle.

Abstract: Electrostatic chucks with reduced current leakage and methods of dicing semiconductor wafers are described. In an example, an etch apparatus includes a chamber, and a plasma source within or coupled to the chamber. An electrostatic chuck is within the chamber. The electrostatic chuck includes a conductive pedestal having a plurality of notches at a circumferential edge thereof. The electrostatic chuck also includes a plurality of lift pins corresponding to ones of the plurality of notches.

Abstract: Shadow ring kits and methods of dicing semiconductor wafers are described. In an example, an etch apparatus includes a chamber, and a plasma source within or coupled to the chamber. An electrostatic chuck is within the chamber, the electrostatic chuck including a conductive pedestal to support a substrate carrier sized to support a wafer having a first diameter. A shadow ring assembly is between the plasma source and the electrostatic chuck, the shadow ring assembly sized to process a wafer having a second diameter smaller than the first diameter.

Abstract: Provided is a system, comprising: an electrical power meter comprising: a network interface; electrical power inputs configured to receive electrical power from a power-distribution system of a vehicle facility configured to host a plurality of vehicles; first and second electrically controlled switches coupled to vehicle power connectors; and a client-side processor configured to communicate with a remote server system; and the remote server system, configured to: cause a user-computing device of a user to display a user interface by which power-delivery is configurable; receive a request to deliver electrical power via a vehicle power connector; and in response, transmitting, to the electrical power meter, a command that causes the client-side processor to adjust the electrically controlled switch.
