    Abstract: System, methods, and other embodiments described herein relate to implementing cooperative management strategies. In one embodiment, a method includes determining a severity score and a risk area. The method may then determine whether vehicles should belong to a first vehicle set, which may perform a cooperative vehicle response action, or a second vehicle set, in which individual response actions may be performed. The method may then generate a cooperative response action or an individual response action corresponding to the cooperative or individual vehicle sets, provided such vehicle sets are not empty.

  • Publication number: 20240416950
    Abstract: A system and method is provided for implementing computer-controlled systems (e.g., vehicle safety and traffic management systems) based on compliance rates. A vehicle system and method are provided that estimate compliance rates in real-time, and have the capability to dynamically modify the computer-controlled instructions generated by a computer-controlled system (e.g., vehicle safety and traffic management systems) in a manner that improves compliance, and in-turn improves overall system performance. For example, a vehicle includes sensors receiving data from a plurality of communicative connected vehicles. The received data is associated with a real-time monitoring of traffic conditions for the vehicle. The vehicle also includes a controller device estimating a compliance rate in real-time based on the received data. The controller device of the vehicle also controls an automated operation of the vehicle using a modified computer-controlled instruction based on the estimated compliance rate.

  • Publication number: 20240388063
    Abstract: An optical grating comprising a refractive index with a periodic pattern that includes a base period ?0; a periodic sampling of the base period, with a first period ?1 and a first duty cycle p1, thereby defining a single-sampled grating (SSG); and a periodic sampling of the SSG, with a second period ?2 and a second duty cycle p2. The resulting dual-sampled grating (DSG) can have a reflection spectrum containing reflection peaks. If two DSGs having different reflection spectra share a common interface, a tunable optical filter can be produced, where electrical or heating means can cause a reflection peak of one spectrum to be shifted to coincide with a reflection peak of the other spectrum, thereby filtering the corresponding wavelength. By inserting between the two DSGs a gain medium and a phase-tuning medium, a laser source structure is realized. Either device can be produced by etching or stacking methods.
