The assembly also includes an electrode preheating circuit configured to provide preheating current through a portion of the welding electrode via a second contact tip of the welding torch, and a voltage sense circuit to monitor a voltage drop across the two contact tips, and the electrode preheating circuit adjusts at least one of the first current or the preheating current based on the voltage drop.

Abstract: A light emitting diode system allows for high current end user LED matrix applications while mitigating internal damage to control circuitry that may be caused by excess current flow. In one example, multiple switches operate in parallel across an LED. When an overvoltage condition is detected in a first switch, a logic circuit determines those switches programed to operate in parallel and causes them to conduct current. This reduces the amount of current flowing through any one switch and mitigates harm to the device. The parallel configuration of switches may be driven by a single pulse width modulated current. This allows the drive current to be divided between parallel transistors, limiting the damaging effects that can be caused by high currents flowing through the transistors.

Abstract: A router receives from a host service a message which is intended for delivery to a mobile device via a wireless network. The message includes an indication field which includes a return packet indication on whether to send a return packet to the host, an identifier field which includes an identifier which identifies the device, and a payload field which includes a payload of the message. When the indication is set to a first, setting and the message is not being delivered to the device, the router sends to the host a return packet which indicates that the message is not being delivered to the device. When the indication is set to a second setting and the message is not being delivered to the device, the router does not send to the host the return packet which indicates that the message is not being delivered to the device.
