  • Patent number: 8075555
    Abstract: Various embodiments provide compositions that exhibit positive temperature coefficient of resistance (PTCR) properties for use in thermal interactions with tissue—including thermal sensing and I2R current-limiting interactions. Embodiments also provide tissue-engaging surfaces having PTCR materials that provide very fast switching times between low resistance and high, current-limiting resistance. One embodiment provides a matrix for an electrosurgical energy delivery surface comprising a PTCR material and a heat exchange material disposed within an interior of the matrix. The PTCR material has a substantially conductive state and a substantially non-conductive state. The heat exchange material has a structure configured to have an omni-directional thermal diffusivity for exchanging heat with the PTCR material to cause rapid switching of the PTCR material between the conductive state and non-conductive state. Preferably, the structure comprises a graphite foam having an open cell configuration.

  • Patent number: 8073550
    Abstract: A system and method for treating subcutaneous histological features without affecting adjacent tissues adversely employs microwave energy of selected power, frequency and duration to penetrate subcutaneous tissue and heat target areas with optimum doses to permanently affect the undesirable features. The frequency chosen preferentially interacts with the target as opposed to adjacent tissue, and the microwave energy is delivered as a short pulse causing minimal discomfort and side effects. By distributing microwave energy at the skin over an area and adjusting power and frequency, different conditions, such as hirsuitism and telangiectasia, can be effectively treated.

  • Patent number: 8005351
    Abstract: A method of heat-treating a workpiece includes generating an initial heating portion and a subsequent sustaining portion of an irradiance pulse incident on a target surface area of the workpiece. A combined duration of the initial heating portion and the subsequent sustaining portion is less than a thermal conduction time of the workpiece. The initial heating portion heats the target surface area to a desired temperature and the subsequent sustaining portion maintains the target surface area within a desired range from the desired temperature. Another method includes generating such an initial heating portion and subsequent sustaining portion of an irradiance pulse, monitoring at least one parameter indicative of a presently completed amount of a desired thermal process during the irradiance pulse, and modifying the irradiance pulse in response to deviation of the at least one parameter from an expected value.

  • Patent number: 8000587
    Abstract: Pulsed processing methods and systems for heating objects such as semiconductor substrates feature process control for multi-pulse processing of a single substrate, or single or multi-pulse processing of different substrates having different physical properties. Heat is applied a controllable way to the object during a background heating mode, thereby selectively heating the object to at least generally produce a temperature rise throughout the object during background heating. A first surface of the object is heated in a pulsed heating mode by subjecting it to at least a first pulse of energy. Background heating is controlled in timed relation to the first pulse. A first temperature response of the object to the first energy pulse may be sensed and used to establish at least a second set of pulse parameters for at least a second energy pulse to at least partially produce a target condition.

  • Patent number: 7974526
    Abstract: An electric radiant heater has a proximity sensor capable of detecting the presence of an object proximate the top surface of the heater's housing. The heater also has a temperature sensor capable of sensing ambient temperature proximate the top surface of the heater's housing. A microcontroller is coupled to the proximity and temperature sensors. Upon the detection of an object atop the heater's housing, the microcontroller determines if the temperature sensor's output is indicative of the presence of ice or snow. If so, a heating element of the heater is allowed to remain in operation. Otherwise, the detected object is considered to be potentially combustible material, and the heating element is switched off by the microcontroller.
