Patent number: 9383292Abstract: A fluidic probe comprising a plurality of oriented fibers with individual fibers having nano-pores in the fiber bodies, the oriented fibers being twisted together, wherein the twisted oriented fibers form micro-pores between the individual fibers, is disclosed. The fluidic probe exhibits excellent flexibility, deployability and absorptive capacity. The enhanced absorptive capacity is due to the fluid absorption via capillary action of the nano-pores and fluid transport via the micro-pores. The probes can also be formed so as to be remotely controlled by electromagnetic fields and thus be used in a hands-free fashion. With these probes, the paradigm of a stationary microfluidic platform can be shifted to include flexible structures that can include multiple microfluidic sensors in a single fibrous probe.Type: GrantFiled: September 12, 2012Date of Patent: July 5, 2016Assignee: CLEMSON UNIVERSITYInventors: Konstantin G. Kornev, Chen-Chih Tsai, David Lukas, Petr Mikes

Patent number: 9291383Abstract: An appliance such as a refrigerator receives a demand response signal indicating a peak demand period and operates the refrigerator in an energy savings mode by disabling an anti-sweat heater. A sensor on an external surface of the refrigerator enables the anti-sweat heater during the peak demand period if moisture is detected by the sensor. A preselected location can be defined where incipient moisture would form such as reducing the amount of insulation in this location. By forming a depression in the location and using an impedance-type sensor, moisture can be easily detected. The sensor signal is sent to the controller which then activates the anti-sweat heater to remove the moisture.Type: GrantFiled: August 19, 2010Date of Patent: March 22, 2016Assignees: Clemson University, Hokkaido UniversityInventor: John K. Besore

Luminescent tension-indicating orthopedic strain gauges for non-invasive measurements through tissue
Patent number: 9179865Abstract: Strain gauges that can provide information with regard to the state of implantable devices are described. The strain gauges can exhibit luminescence that is detectable through living tissue, and the detectable luminescent emission can vary according to the strain applied to the gauge. A change in residual strain of the device can signify a loss of mechanical integrity and/or loosening of the implant, and this can be non-invasively detected either by simple visual detection of the luminescent emission or through examination of the emission with a detector such as a spectrometer or a camera.Type: GrantFiled: August 7, 2013Date of Patent: November 10, 2015Assignee: Clemson UniversityInventors: Jeffrey Anker, Melissa Rogalski, Dakota Anderson, Jonathon Heath -
