  • Publication number: 20160355904
    Abstract: A device for additive manufacturing of an object. The device includes: a first probe configured to form the object; and a work-hardening second probe, where the work-hardening second probe is an ultrasonic probe, and further where the second probe is configured to emit ultrasonic energy to modify a substructure of the object during manufacture; wherein the first probe is configured to increase a temperature of at least a portion of a first layer of the object facing the first probe, to a first depth; and wherein the second probe is configured to work-harden the at least a portion of the first layer of the object facing the first probe, to a second depth, the second depth being greater than the first depth.

  • Patent number: 7652586
    Abstract: According to one embodiment, a first capacitive element may be provided and associated with a surface where a fouling layer is to be detected. A second capacitive element may also be provided, and a capacitance between the first and second capacitive elements may be used to detect formation of the fouling layer. According to another embodiment, a thermal device is provided proximate to a surface where a fouling layer is to be detected. A detector (e.g., a thermometer or vibration detector) may detect a condition associated with the surface, and formation of the fouling layer may be determined based at least in part on the condition.

  • Patent number: 7633725
    Abstract: A system is presented. The system includes detection circuitry configured to detect occurrence of a zero crossing of an alternating source voltage or an alternating load current. The system also includes switching circuitry coupled to the detection circuitry and comprising a micro-electromechanical system switch. Additionally, the system includes control circuitry coupled to the detection circuitry and the switching circuitry and configured to perform arc-less switching of the micro-electromechanical system switch responsive to a detected zero crossing of an alternating source voltage or alternating load current.
