  • Faucet including capacitive and ultrasonic sensing
    Patent number: 9976291
    Abstract: A fluid delivery apparatus includes a spout, an ultrasonic sensor, and a capacitive sensor. The ultrasonic sensor is configured to detect the presence of a user adjacent the spout when enabled. The capacitive sensor is configured to define a capacitance sensing field in an area near the spout and also to detect a presence of a user. A controller is coupled to the capacitive sensor and the ultrasonic sensor. The controller is programmed to detect the presence of a user in the capacitance sensing field based on an output signal from the capacitance sensor. The controller is also programmed to enable the ultrasonic sensor in response to detecting the presence of the user in the capacitance sensing field with the capacitive sensor, thereby reducing the amount of power used by the ultrasonic sensor.

  • Welding wire preheating system and method
    Patent number: 9950383
    Abstract: In a welding system, a preheating process is carried out prior to initiation of a welding arc, such as upon depression of a trigger or switch on a welding torch. The preheating process involves generation and application of desired currents and voltages to a welding electrode from a power supply. Preheating is continued until the welding electrode reaches a desired temperature or resistance, which may be determined by reference to an increasing voltage, a decreasing current, a peaked and declining voltage, resistance and/or power measurements, and so forth. Following preheating, a desired welding process may begin with initiation of the welding arc.
