Abstract: A system is provided that may include a first communication controller that may communicate with a vehicle system formed from two or more vehicles. The first communication controller may operate in different modes, including a first mode to control movement of the vehicle system without repeating any control signals communicated between the vehicles, and in a second mode to monitor different frequencies for receipt of the control signals, receive and repeat a first control signal of the control signals at a first frequency, and receive and repeats a second control signal of the control signals at a second frequency. The first communication controller may also operate in a third mode in which the first communication controller may monitor the first frequency but not the second frequency for the first control signal, receives the first control signal at the first frequency, and repeats the first control signal at the first frequency.

Abstract: An apparatus for suspending air bubbles in a fluid path of a fluid injector system includes an internal chamber having a curved interior wall defined within the housing, an inlet fluid pathway in fluid communication with the internal chamber, and an outlet fluid pathway in fluid communication with the internal chamber. The inlet fluid pathway extending into the chamber at a tangent to the curved interior wall, and the outlet fluid pathway spaced from the inlet fluid pathway such that fluid flowing into the internal chamber via the inlet fluid pathway is directed away from the outlet fluid pathway. The internal chamber is configured to create an internal fluid vortex in an injection fluid entering the internal chamber from the inlet fluid pathway, and wherein the internal fluid vortex at least temporarily suspends one or more air bubbles in the fluid in the internal vortex and delays the passage of the one or more air bubbles to the outlet fluid pathway.

Abstract: Systems and methods for locating microserver nodes in proximity to edge devices using georouting. Microservers automatically form a global peer-to-peer network to serve edge functions and content to edge devices. Edge devices use HyperText Transfer Protocol (HTTP) to execute serverless functions or otherwise retrieve data from edge nodes and/or microservers located in proximity to the HTTP client. The cloud platform locates the nearest edge node and/or microserver. Edge devices georoute HTTP requests to the nearest edge node and/or microserver. Serverless functions are implemented in secure, isolated environments using a blockchain.

Abstract: A communication device and method may include at least one tuner circuit that monitors at least a first frequency channel and a second frequency channel. A controller of the radio receiver may measure a first received signal strength indicator (RSSI) value over time for the first frequency channel and a second RSSI value over time for the second frequency channel. The first and second RSSI values are based on a signal strength of radio frequency (RF) energy received on the first and second frequency channels, respectively. The controller may detect a leader portion of a message on the first frequency channel responsive to a change in the first RSSI value exceeding a step change threshold. The controller may extract, via a detector circuit, message data from a carrier wave of the RF message.

Abstract: A communication system may include communication devices configured to be onboard vehicles in a multi-vehicle system. Each of the communication devices may operate in a lead mode, a repeater mode, or a trail mode. The communication devices operating in the lead mode may transmit a command signal to control movement of the multi-vehicle system. The communication devices operating in the repeater mode may re-transmit the command signal received from the one or more communication devices operating in the lead mode. The communication devices operating in the trail mode may receive the command signal received from the one or more communication devices operating in the lead mode or in the repeater mode. Each of the communication devices may be remotely switched between the lead mode or the trail mode to the repeater mode.

Desirably, the target antigen is provided as a fusion protein with the cytolysin. The inventors have found that cytolysins may be particularly effective for stimulation of mucosal immune responses against the target antigen.

Abstract: A hybrid device can implement functionality to automatically configure itself to form a home network with other network devices. If it is determined that the hybrid device is the central access point of a hybrid network, operating parameters are determined for the central access point. The central access point can then operate in conjunction with other non-CAP hybrid devices of the hybrid device to determine how to configure the non-CAP hybrid device. The configuration of the non-CAP hybrid device can be determined based, at least in part, on a communication link performance measurement between the CAP and the non-CAP hybrid device. Furthermore, the hybrid network can also be monitored to ensure that the hybrid devices do not repeatedly or randomly switch between different configurations.

Abstract: An asymmetric mixed-mode transceiver may determine to communicate with a destination powerline communication device. The asymmetric mixed-mode transceiver may determine whether an operational mode associated with the destination powerline communication device is a multiple-output multiple-input (MIMO) mode or a single-output single-input (SISO) mode. The asymmetric mixed-mode transceiver may dynamically change its operational mode to either the MIMO mode or the SISO mode to match the operational mode of the destination powerline communication device. The asymmetric mixed-mode transceiver may receive a communication from a source powerline communication device. The asymmetric mixed-mode transceiver may determine whether an operational mode associated with the source powerline communication device is the MIMO mode or the SISO mode. The asymmetric mixed-mode transceiver may dynamically change its operational mode to match the operational mode of the source powerline communication device.
