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.

Systems are provided for determining an estimated volumetric ratio of a material to total materials in a mixing vessel. In various embodiments, the systems may comprise: a summation block for determining an estimated volumetric rate of change of the material in the mixing vessel; an integration element for determining an estimated volume of the material in the mixing vessel based on the estimated volumetric rate of change of the material in the mixing vessel; a first gain element for converting the estimated volume of the material in the mixing vessel to the estimated volumetric ratio of the material to the total materials; and a second gain element for converting the estimated volumetric ratio of the material to the total materials to an output flowrate of the material from the mixing vessel.

Systems are provided for controlling a volumetric ratio of a material to total materials in a mixing vessel. In various embodiments, the systems may comprise: a volumetric ratio observer for estimating the volumetric ratio of the material to the total materials in the mixing vessel and an output flowrate of the material from the mixing vessel; a flow regulator coupled to the volumetric ratio observer for dynamically recomputing a commanded input flowrate of the material based on outputs of the volumetric ratio observer; and a flow modulator coupled to the flow regulator for adjusting an input valve of the material based on the commanded input flowrate of the material. In an embodiment, the mixing vessel comprises a first mixing vessel partially separated from a second mixing vessel. In this case, a height observer may be used to estimate a height of the total materials in the second mixing vessel.

A circuit for a three-phase brushless motor, which can change phase stator windings with keeping a predetermined phase difference to a phase of a back electromagnetic force generated in any one of the phase stator windings, even if a number of rotation changes extremely, and thereby which can reduce a change of a torque and always keep the most suitable efficiency in driving. The circuit for the three-phase brushless motor comprises a first counter for checking a time of a cycle of a zero cross of a back electromagnetic force detected by a back electromagnetic force detector, and a second counter for counting the time checked by the first counter at a clock having two times as high a frequency as the first counter, and determines a timing of changing the phase stator windings on the basis of an output outputted from the second counter.

A method for providing community information concerning an accommodation area includes the steps of (a) inputting community information of the accommodation area to a storage medium; (b) creating a television presentation and a web presentation using software, wherein the software imports the community information from the storage medium and automatically formats and lays out the community information into the television presentation and the web presentation; (c) applying presentation elements having user-modifiable rules associated therewith to the television presentation and the web presentation; (d) transmitting the television presentation to the accommodation via a distributed communications network; and (e) optionally displaying the web presentation on a web site associated with the accommodation area. A system for creating, managing and delivering community information is also disclosed.

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.
