Patent number: 10105080Abstract: Devices are provided that include a plurality of microneedles that penetrate skin and that receive interstitial fluid from the skin tissue. The microneedles are further configured to direct the received interstitial fluid to nanosensors configured to change an optical property based on interaction with an analyte in the received interstitial fluid, allowing optical detection of the analyte. Direction of the received interstitial fluid to the nanosensors can be facilitated by a pump configured to control the flow rate of the interstitial fluid through the microneedles. Such devices could be configured to detect the analyte independently or in combination with a reader device configured to be periodically mounted to the devices and to detect the analyte. Further, such devices can include delivery systems configured to transdermally deliver a drug or other substance into or through the skin in response to a detected concentration, presence, or other property of the analyte.Type: GrantFiled: December 29, 2014Date of Patent: October 23, 2018Assignee: VERILY LIFE SCIENCES LLCInventors: Kimberly Kam, Jerrod Joseph Schwartz, Gary Tong

Patent number: 10107664Abstract: A measurement tool for circle area includes a cylinder, a rectangular container and a pipe. The cylinder is provided with a first opening and filled with a liquid. The rectangular container is provided with a second opening, and at least side surface of the rectangular container is provided with at least scale table. The pipe is arranged on the cylinder and the rectangular container and connected with the first opening and the second opening. When the cylinder is tilted, the liquid flows to the rectangular container through the pipe, and a volume of the liquid in the rectangular container is figured out according to a length, a width and a height of the rectangular container and the scale table. The volume equals an inner-cylinder volume of the cylinder. An inner-circle area of the cylinder is obtained according to the inner-cylinder volume and a height of the cylinder.Type: GrantFiled: March 3, 2017Date of Patent: October 23, 2018Assignee: NATIONAL TAIWAN NORMAL UNIVERSITYInventors: Jung-Hsuan Chen, Chin-Guo Kuo, Chao-Fu Shu

Patent number: 10094826Abstract: Described is a method aiding in the assessment of rheumatoid arthritis (“RA”). The method is used in assessing RA in vitro. It is practiced by analyzing biochemical markers, including measuring the concentration of anti-CCP and anti-PIK 3CD and correlating the concentrations determined to the absence or presence of RA. Also disclosed is the use of a marker panel including anti-CCP and anti-PIK3CD in the diagnosis of RA and it teaches a kit for performing the method. Also described is the use of a marker panel comprising anti-CCP and anti-PIK3CD to differentiate RA from other autoimmune diseases, preferably osteoarthritis (OA).Type: GrantFiled: August 10, 2017Date of Patent: October 9, 2018Assignee: Roche Diagnostics Operations, Inc.Inventors: Herbert Andres, Stefan Weiser, Johann Karl, Ursula Kunert, Florian Grupp

Patent number: 10094785Abstract: A method and system for optically inspecting parts are provided wherein the system includes a part transfer subsystem including a transfer mechanism adapted to receive and support a part at a loading station and to transfer the supported part by a split belt conveyor so that the part travels along a first path which extends from the loading station to an inspection station at which the part has a predetermined position and orientation for inspection. An illumination assembly simultaneously illuminates a plurality of exterior side surfaces of the part with a plurality of separate beams of radiation. A telecentric lens and detector assembly forms an optical image of at least a portion of each of the illuminated side surfaces of the part and detects the optical images. A processor processes the detected optical images to obtain a plurality of views of the part which are angularly spaced about the part.Type: GrantFiled: June 29, 2017Date of Patent: October 9, 2018Assignee: GII Acquisition, LLCInventors: Robert Joseph Offenborn, Christopher Michael Alexander, Gregory Martin Nygaard, Michael George Nygaard
