Patent number: 8904877Abstract: A device, inserted in a running shoe is used to track the accumulation of destructive compression cycles within the shoe and to indicate this information to the user through a series of integrated indicators. The device has an advantage of being able to be placed in any shoe without compromising the construction or performance of the shoe. An additional advantage of the invention is the improved accuracy of the information by improving both the stability and longevity of the sensor system and the ability to distinguish destructive, partially destructive and nondestructive compressions. Another advantage of the invention is the reduction of the cost of construction while achieving a lifetime in excess of the shoe. Yet another advantage of the invention is the user interface, which is contained completely within the device allowing the user to view the information within the shoe.Type: GrantFiled: December 3, 2012Date of Patent: December 9, 2014Assignee: ParaWare LLCInventors: Aaron Burke, Daniel Jannsen, Derk Smid, Andrew Hills

Patent number: 8875591Abstract: Methods of measuring at least one rheological property of diamond particles used in the manufacture of polycrystalline diamond are disclosed. Diamond particles are provided including a plurality of unsintered diamond particles. A rheological property (e.g., a torsional mechanical property or other flow property) of the diamond particles is measured. By comparing the measured value of the torsional mechanical property to that of a baseline known to correlate to the desired target specification, it may be determined whether the diamond particles are within an acceptable range relative to the target specification. Such a method may be incorporated into methods for manufacturing a polycrystalline diamond compact to ensure the quality of a polycrystalline diamond table thereof.Type: GrantFiled: January 27, 2011Date of Patent: November 4, 2014Assignee: US Synthetic CorporationInventor: Amy Leigh Rodriguez

Publication number: 20140305224Abstract: The present disclosure provides a multi-touch testing system and the fixture thereof. The multi-touch testing system comprises a multi-touch testing fixture and a monitoring device. The monitoring device is connected electrically with the multi-touch testing fixture and a device under test disposed at the multi-touch fixture. Thereby, the monitoring device activates the multi-touch testing fixture. The multiple test heads of the multi-touch testing fixture press the device under test simultaneously. Meanwhile, the device under test generates at least a signal. The monitoring device judges if the device under test passes the multi-touch test according to the signal. The pressure of each test head of the multi-touch testing fixture according to the present disclosure is identical to that of any other. In addition, the structure is simplified.Type: ApplicationFiled: February 14, 2014Publication date: October 16, 2014Applicant: WISTRON CORPORATIONInventors: Xiao-Bao ZHANG, Shou-Lun CHANG
