Publication number: 20240074677Abstract: A monitoring apparatus and method includes a monitor, a sensor comprising a wireless connection with the monitor, and an adapter comprising the wireless connection with the monitor and a wired or wireless connection with a remote monitoring station. The monitor is designed to wirelessly pair with the sensor and/or the adapter when being only positioned by a user in a closed proximity to the sensor and/or the adapter or in a direct contact with the sensor and/or the adapter and without an additional action by the user and/or a wired connection between the monitor and the sensor and/or the adapter. A pairing alignment mark may be provided on each of the monitor, sensor and adapter.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Applicant: TIDI Products, LLCInventors: Justin K. Thomas, Samantha L. McCarthy, Eduardo Hernandez, Brian Nathan Young, Melissa Waldroup, Joe Samz

Patent number: 8705924Abstract: Various embodiments described include optical fiber designs and fabrication processes for ultra high numerical aperture optical fibers (UHNAF) having a numerical aperture (NA) of about 1. Various embodiments of UHNAF may have an NA greater than about 0.7, greater than about 0.8, greater than about 0.9, or greater than about 0.95. Embodiments of UHNAF may have a small core diameter and may have low transmission loss. Embodiments of UHNAF having a sufficiently small core diameter provide single mode operation. Some embodiments have a low V number, for example, less than 2.4 and large dispersion. Some embodiments of UHNAF have extremely large negative dispersion, for example, less than about ?300 ps/nm/km in some embodiments. Systems and apparatus using UHNAF are also disclosed.Type: GrantFiled: September 11, 2012Date of Patent: April 22, 2014Assignee: IMRA America, Inc.Inventors: Liang Dong, Xiang Peng, Brian K Thomas

Publication number: 20130294736Abstract: Various embodiments include photonic bandgap fibers (PBGF). Some PBGF embodiments have a hollow core (HC) and may have a square lattice (SQL). In various embodiments, SQL PBGF can have a cladding region including 2-10 layers of air-holes. In various embodiments, an HC SQL PBGF can be configured to provide a relative wavelength transmission window ??/?c larger than about 0.35 and a minimum transmission loss in a range from about 70 dB/km to about 0.1 dB/km. In some embodiments, the HC SQL PBGF can be a polarization maintaining fiber. Methods of fabricating PBGF are also disclosed along with some examples of fabricated fibers. Various applications of PBGF are also described.Type: ApplicationFiled: June 11, 2013Publication date: November 7, 2013Inventors: Liang Dong, Brian K. Thomas, Shigeru Suzuki, Libin Fu
