Abstract: A computer-implemented method for alerting passenger vehicles of approaching emergency vehicles is implemented by an alert management computing device. The method includes receiving an emergency vehicle alert request message from an emergency vehicle transmitter, receiving passenger vehicle location data from a plurality of passenger vehicle user computing devices located in a plurality of passenger vehicles, wherein the passenger vehicle location data includes a present passenger vehicle location and a present passenger vehicle trajectory, identifying an alert zone for the emergency vehicle based on the present emergency vehicle location and the present emergency vehicle trajectory, identifying a vehicle zone for each of the plurality of passenger vehicles, identifying a subset of the passenger vehicles within the alert zone by comparing each vehicle zone to the alert zone, and transmitting a warning to the subset of passenger vehicles via the passenger vehicle user computing devices.

Abstract: A pilot-operated relief valve assembly can include a relief valve, and a pressure detection assembly. A valve lift factor or indicator of relief flow can be determined based on pressure measurements gathered by the pressure detection assembly.

Abstract: The present invention is directed to allowing a more secure initial, and continuous authentication of virtual private network (VPN) tunneling. The device of the present invention contains its own microprocessor and operating system which connects to the host system via a universal serial bus (USB) or another coupling mode. The present invention involves executing and storing of the VPN software, certificates, credentials and sensors on the device, which allows for more security and manageability as opposed to executing the VPN on the host system. The device continuously authenticates the presence of the user via biometrics or the presence of second device, including a smartphone, a smartwatch, an NFC ring or a custom device with a microprocessor, via Quick Response (QR) Codes, Near-Field Communication (NFC) or Bluetooth Low Energy (LE) proximity authentication to activate or deactivate the VPN tunnel.

Abstract: Embodiments of the invention provide a relief valve body arranged between an inlet and an outlet. The relief valve body includes an expanding nozzle extending along an axis, a first ramp extending in an arcuate path from an apex to a first terminal point, and a second ramp extending in an arcuate path from the apex to a second terminal point. The first ramp and the second ramp define an expanding flow area for a fluid flow between the inlet and the outlet.

Abstract: Embodiments of the invention provide a relief valve body arranged for connecting to a pressure vessel. The relief valve body includes an inlet configured to connect to a pressure vessel and an integrated nozzle downstream from the inlet and extending along an axis. The integrated nozzle includes a nozzle exterior surface, a nozzle bulb, and a valve seat and defines a nozzle expansion region. The relief valve body further includes a redirecting pallet, a valve interior surface having at least one ramped portion downstream from the integrated nozzle and redirecting pallet, and an outlet downstream from the at least one ramped portion.

Abstract: Embodiments of the invention provide a vibration damping system including a fixed element, a moveable element arranged to move linearly along an axis relative to the fixed element in response to a non-mechanical force, and an inerter element coupling the moveable element to the fixed element, and configured to convert the linear motion of the moveable element into rotational motion about the axis. The vibration damping system may be applied to many types of valves. In some embodiments, the vibration damping system may be applied to pressure relief valves. In some embodiments, the moveable element rotates to provide inertial damping. In other embodiments, the inerter element rotates to provide inertial damping.

Abstract: A system for verifying the presence and identity of a user on a remote computer having a server connected to a network, the network being connected to one or more remote computers. The system further includes a microcontroller connected to the remote computer by means such as USB, and registered with the server. The USB microcontroller is authenticated upon being inserted into a remote computer and is continuously authenticated thereafter until the user disconnects the USB microcontroller from the computer. When the proper authentication is satisfied, the system runs a secure web browser that is used to access websites that may have a user's confidential and sensitive data. Upon disconnecting the USB device, the secure web browser closes and none of the session data is stored locally on the computer.
