A dual head contrast media injection system performs a patency check or test injection, determining flow rate and/or flow volume from the programmed protocol. The tubing that connects syringes to a patient shares only a short common section near to the patient. Appropriate injection steps are taken to compensate for tubing elasticity. A wireless remote control and a touch screen control are provided, improving functionality and information delivery. The display brightness is controlled based on the ambient light, and the display panel includes a double swivel permitting re-orientation. The orientation of the display may also be controlled based on, e.g., the current step, the tilt angle of the powerhead, or a manual control. Furthermore, the display is customizable to identify the type of fluid (contrast, saline, etc.) on either side of the injector, to provide matched color coding, and to provide a folder/tab analogy for retrieving injection protocol parameters.

Live media content is delivered in substantially real-time to a player device from a streamer and through a content delivery network. The streamer receives live media content and encodes and streams the content over the content delivery network. The content delivery network is configured to provide minimal buffering. A player device accessing the streaming channel receives media frames and buffers the frames while rending the received frames in order of receipt. If the buffer is loaded to the point that the currently rendered data lags the actual live feed by more than a threshold amount of time, the player skips over one or more video frames to bring the rendered content more current. For instance, the buffer can be flushed and more recent content can be received from the content delivery network.

A system and method for controlling toy vehicles has a plurality of pads coupled to a central station. Switches in the pads may be closed to select toy vehicles and the operation of motors for moving the vehicles forwardly, rearwardly, to the left and to the right and moving upwardly and downwardly a receptacle or bin for holding transportable elements (e.g. marbles). The pads may be set in a mode to allow sharing of a vehicle by more than one pad. The pads are connected by wires to the central station, and may be interrogated selectively, sequentially or simultaneously by the central station. The central station forms packets of signals representative of the switch closures of the interrogated pads, and transmits the packets over a modulated carrier frequency to receivers in the vehicles. Each of the packets includes a binary signal addressing the vehicle selected by the pad whose switch closures are represented by the packet of data. The central station prioritizes the transmission of the packets to improve vehicle control. An accessory, or a second central station, may be coupled to a smart port of the first central station. When the pads are interrogated by the central station, the signals from the pads may be routed to the accessory or second central station for processing, then sent back to the first central station for transmission to the vehicles. The pads include a flashback feature that automatically selects a previously selected vehicle. The motors of the vehicles may be energized using pulse width modulation to control the speed of the motor. Signals received by the vehicle are asserted to the motors in the first part of a duty cycle. The vehicles monitor all packets, and decode packets addressed to the vehicle to execute the commands represented by signals contained within the packet. When a packet is determined to be invalid, the vehicle ignores the packet.
