Abstract:

Systems and methods for redirecting network traffic include a policy server configured to be in communication with a policy database and a client disposed on a remote device. The policy server is configured to receive an inquiry from the client regarding a universal resource locator (URL) request and, based on a policy obtained from the policy database, cause the client to control the remote device such that network traffic associated with the URL request is routed (tunneled) via a particular interface, e. g. , a virtual private network (VPN) connection, when so required by the policy, and network traffic associated with the URL request is routed over a different VPN connection or a non-VPN connection when so required by the policy.

Abstract:

An NMR system includes a radio frequency (RF) NMR application-specific integrated circuit (ASIC) chip configured to generate an RF output signal and a rectifier configured to receive the RF output signal and convert the RF output signal to (a) a direct current (DC) pulsed field gradient (PFG) signal or (b) a DC trigger signal for at least one of (i) activating at least one component of an NMR system external to the NMR RF ASIC chip and (ii) synchronizing at least one component of an NMR system external to the NMR RF ASIC chip.
