Patent number: 8610036Abstract: A device for monitoring a heating apparatus that includes a default deactivated motion detector for determining whether a person is proximate the heating apparatus. The device includes a default deactivated heat sensor for determining whether the heating apparatus has a temperature that is above a threshold. The device includes an internal timer for cyclically repeating a first countdown. The heat sensor is temporarily activated once during each of the repeated first countdowns. The internal timer performs a second countdown when the activated heat sensor determines that the heating apparatus has the temperature that is above the threshold. The second countdown is reset each time the motion detector determines that a person is proximate the heating apparatus. The device includes an alarm configured to notify a user when the internal timer reaches the end of the second countdown.Type: GrantFiled: October 22, 2010Date of Patent: December 17, 2013Inventors: Robert C. Ewell, Jr., Douglas L. Garmany, Charles T. Kelly, Charles Philip Wasilewski

Patent number: 8598497Abstract: A system and method for controlling the power delivered to cookware by a power control system that comprises a heating control user interface that is set by the user to a particular heating control user interface set point within an operating range. A controller derives from the heating control user interface set point a desired cookware temperature set point, and, over at least a first portion of the operating range that encompasses the boiling range, also derives from the heating control user interface set point a maximum limit of power that can be delivered to the cookware to maintain the cookware at the desired cookware temperature set point. The maximum power limit varies monotonically over the first portion of the operating range.Type: GrantFiled: March 29, 2011Date of Patent: December 3, 2013Assignee: Bose CorporationInventors: Adam Broders, Christopher B. Ickler, Kenneth D. Jacob

Patent number: 8592727Abstract: Flash lamps connected to short-pulse circuits and flash lamps connected to long-pulse circuits are alternately arranged in a line. The duration of light emission from the flash lamps connected to the long-pulse circuits is longer than the duration of light emission from the flash lamps connected to the short-pulse circuits. A superimposing of a flash of light with a high peak intensity from the flash lamps that emit light for a short time and a flash of light with a gentle peak from the flash lamps that emit light for a long time can increase the temperature of even a deep portion of a substrate to an activation temperature or more without heating a shallow portion near the substrate surface more than necessary. This achieves the activation of deep junctions without causing substrate warpage or cracking.Type: GrantFiled: November 17, 2011Date of Patent: November 26, 2013Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Kenichi Yokouchi

Patent number: 8575521Abstract: Temperature control in an RTP system can be improved by consideration of one or more witness structures different from the wafer (or other semiconductor object) being processed. For example, power coupling between the RTP heating system and witness structure can be used to adjust one or more control parameters, such as model definitions, that are used by the RTP system to control wafer heating. As another example, a stored trajectory of a desired witness structure temperature or other property can be used as a basis for control during a processing cycle. Thus, the witness structure may be controlled “closed-loop” while the wafer is heated “open-loop.” As a further example, a heat flux between the RTP heating system and witness structure can be used to determine radiant energy from the heating system that is incident on the witness structure. One or more control actions can be taken based on this incident energy.Type: GrantFiled: April 1, 2008Date of Patent: November 5, 2013Assignee: Mattson Technology, Inc.Inventors: Zsolt Nenyei, Paul Janis Timans

Patent number: 8525083Abstract: A hot water heater and method that includes power consumption reporting to enable consumers to better understand and control the energy usage and/or efficiency of the hot water heater. Monitoring energy consumption of an electric hot water heater having at least one electrical load that is selectively activated by a controller of the hot water heater includes sensing the amount of time the at least one electrical load is activated multiplying the amount of time by a known value corresponding to a power rating of the electrical load to determine energy consumed, and displaying on a display device an indicator corresponding to the energy consumed.Type: GrantFiled: September 17, 2010Date of Patent: September 3, 2013Assignee: General Electric CompanyInventors: Jay Andrew Broniak, Joseph Mark Brian
