Patent number: 8684595Abstract: Systems and methods related to the determination of one or more mechanical characteristics of a structural element are generally described. In some embodiments, a mechanical characteristic (e.g., a crack, a deformation, an inclusion, etc.) can be determined based at least in part upon the determination of a temperature generated, for example, by passing a current through a network of structures within the structural element. For example, in some embodiments, the structural element can comprise a network of electrically conductive nanostructures and, in some cases, a primary structural material that is not substantially electrically conductive. An electrical current can be passed through the network of electrically conductive nanostructures (e.g., by passing current through an electrical circuit comprising the network of electrically conductive nanostructures). This may result in resistive heating (also known as Joule-effect heating) of the nanostructure network.Type: GrantFiled: November 10, 2010Date of Patent: April 1, 2014Assignee: Massachusetts Institute of TechnologyInventors: Brian L.

The method turns on the resistor before turning on a coolant pump and samples the temperature at sample intervals over a predetermined period of time. The method then calculates an integral or differential of the sampled temperatures and compares that value with a calibrated threshold. If the temperature value is not greater than the threshold, meaning that the temperature indicates no cooling fluid is present, the algorithm disables the resistor for heating purposes, but maintains operation of the resistor for pre-charge purposes.Type: ApplicationFiled: January 24, 2012Publication date: July 25, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: ANDREW J.

Patent number: 8482237Abstract: A vehicle includes a power source, a motor, and a computing device. The power source provides electrical energy to the motor, and the motor generates rotational motion from the electrical energy received. The computing device is configured to estimate a temperature of the motor in real time based at least in part on a thermal model of the motor.

Patent number: 8484759Abstract: An approach for the thermomechanical characterization of phase transitions in polymeric materials (polyethyleneterephthalate) by band excitation acoustic force microscopy is developed. This methodology allows the independent measurement of resonance frequency, Q factor, and oscillation amplitude of a tip-surface contact area as a function of tip temperature, from which the thermal evolution of tip-surface spring constant and mechanical dissipation can be extracted. A heating protocol maintained a constant tip-surface contact area and constant contact force, thereby allowing for reproducible measurements and quantitative extraction of material properties including temperature dependence of indentation-based elastic and loss moduli.Type: GrantFiled: August 17, 2010Date of Patent: July 9, 2013Assignee: UT-Battelle, LLCInventors: Stephen Jesse, Sergei V.

Publication number: 20130163634Abstract: A method of controlling the temperature of a probe in materials testing apparatus, and apparatus operating by that method are disclosed. The apparatus includes heating elements that can by supplied with energy to apply heat to the probe. The method has a heating phase. In the heating phase, closed-loop temperature control is used to supply energy to the heating elements to heat the probe to a target temperature. When the probe has reached the target temperature, the average power that is being supplied to the heating elements is determined. Then, in a temperature maintenance phase, a continuous constant source of energy at a power that is substantially equal to the determined average power is supplied to the heating elements to maintain the probe at the target temperature.Type: ApplicationFiled: February 21, 2011Publication date: June 27, 2013Applicant: MICRO MATERIALS LTDInventors: James Frank Smith, Nicholas Pickford

Patent number: 8454229Abstract: Two vertically offset thermistors for sensing a fluid such as oil and refrigerant in a compressor shell are monitored by a method that takes into account rapidly changing conditions within the shell. The system can determine the fluid's sump temperature, high/low liquid levels, and can determine whether the thermistors are sensing the fluid as a liquid, gas, or a mixture of the two, such as a foam or mist of liquid and gas. For greater accuracy, thermistor readings can be dithered and filtered to provide temperature or voltage values having more significant digits than the readings originally processed through a limited-bit A/D converter. For faster response, limited microprocessor time is conserved by sampling thermistor readings at strategic periods that enable the microprocessor to identify certain conditions and temperatures via simple delta-temperature ratios and undemanding equations rather than resorting to exponential functions or lookup tables to determine time constants.Type: GrantFiled: December 3, 2010Date of Patent: June 4, 2013Assignee: Trane International Inc.Inventors: Ronald W.
