Patent number: 11046247Abstract: A system and method for determining a probability that a driver will detect a hazard while driving. An eye tracker tracks the driver's forward and non-forward glance durations. A probability calculator categorizes the glance durations into an observation type and selects a transition matrix specific to that observation type. The probability calculator groups the glance durations and observation type into a tuple and calculates a probability that the driver will detect a hazard in the current time segment based on the tuple, the previous time segment's detection state, and the transition matrix. Based on whether the determined probability is above or below a threshold, the current time segment detection state is stored in memory as a detect state (driver is likely to detect a hazard) or a non-detect state (driver is not likely to detect a hazard). The driver is alerted if determined to be in a non-detect state.Type: GrantFiled: January 10, 2019Date of Patent: June 29, 2021Assignee: North Carolina A&T State UniversityInventor: Hyoshin Park

Patent number: 10985699Abstract: A differential constructive wave oscillator device including a single, continuous differential transmission line that is arranged into first and second parallel traces in the form of a Mobius loop. The continuous transmission line includes first and second crossover points, each of which provides for a point of inflection between the first and second traces. In each stage of the device, both the first and second traces of the transmission line carry the forward traveling wave signal from a differential input port to a differential output port. Each phase includes a differential delay section that provides for a phase shift between a signal on the first trace and a signal on the second trace. Each phase additionally includes a differential feedback amplifier that amplifies the forward traveling wave signal at the differential output port, generates a differential feedback signal, and routes the differential feedback signal to the differential input port.Type: GrantFiled: March 4, 2019Date of Patent: April 20, 2021Assignee: North Carolina A&T State UniversityInventors: Numan S.

Publication number: 20170127674Abstract: Alexandrian laurel (Danae racemosa L.) is a highly demanded evergreen shrub. However, seed germination often takes up to 12 to 18 months with a germination rate of only about 20%. Also, due to its slow-growth rate, it typically takes up to six years to produce a saleable one-gallon size plant. Germinating seeds in the presence of cytokinins and/or auxins increased in vitro shoot multiplication and seedling quality enhancement. Benzyladenine was found to balance seedling development by simultaneously accelerating shoot growth and slowing down root growth, whereas thidiazuron significantly promoted shoot multiplication and proliferation by producing 5-30 shoots per seed.Type: ApplicationFiled: September 12, 2016Publication date: May 11, 2017Applicant: North Carolina A&T State UniversityInventors: Guochen Yang, Zhongge Lu
