Abstract:
A power injector (40) includes a movable ram (74) operable to interface with and move a plunger (90a/b) of a syringe (86a/b). The power injector (40) may be operable to automatically determine a proper home position for the particular type of syringe (86a/b) to be used in a fluid injection sequence. The power injector (40) may also include ram homing logic (182) operable to automatically move the ram (74) to a home position after an injection. Such automatic homing of the ram (74) may, for example, be initiated by the end of an injection sequence in preparation for another injection sequence, by the opening of a faceplate (102a/b), by a user input, or by any combination thereof.
Abstract:
A coating material application system includes two or more guns with associated purge receptacles so that a gun may be purged and cleaned while the operator is using a different gun for a coating operation. Optionally, the cleaned and purged gun may be pre-charged with coating material so that it is ready to be used for a coating operation as soon as the operator is finished using the other gun. The purge receptacle may optionally include blow off devices for directing pressurized air at exterior surfaces of the gun. A purge operation may optionally include purging one or more supply devices such as for example, feed hoses, manifolds and pumps.
Abstract:
Material application system provided with a wireless identification technology for parts being processed and for components of the material application system. An exemplary technology is RFID. The RFID device can be used for many different functions including part identification, repair and maintenance programs, and inventory control.
Abstract:
Object identification apparatus and method are provided in which one or more features of an object are detected and linked with an object identifier. Features of the object itself are used to identify the object. A configurable identification system is provided by which a user can relate a sensor output to an object identifier without having to program or re-program software or firmware. In one embodiment, sensors used as control devices are also used as the identification sensors.

Abstract:
An internal power supply for an electrostatic application device includes a programmable digital control circuit (104) that produces a time variant drive signal (106) to a high voltage multiplier circuit (108). The internal power supply is fully installed inside the device so that only a fixed low DC voltage input (16) is needed for the power supply. The control circuit (104) may optionally utilize stored characteristic parameters of the power supply as well as feedback signals that correspond to operational characteristics of the power supply during a spraying operation.
Abstract:
A power supply (80) for an electrostatic spray gun (70) includes a circuit for dynamic manipulation of an operational loadline. Various embodiments are provided, including an analog circuit, a variable frequency circuit, a variable waveform circuit and a variable impedance circuit. The manipulation circuit may be used with either or both of an internal and an external feedback arrangement.
Abstract:
A medical fluid injector system (450) is disclosed that may utilize one or more of flow rate determination logic (130), injection volume determination logic (132), display control logic (134), drive ram motion control logic (136), and pressure monitoring logic (138). The flow rate determination logic (130), injection volume determination logic (132), and display control logic (134) each may utilize a concentration input (172, 192, 202) to calculate flow rates, injection volumes, and generate multi-color graphics, respectively, for a simultaneous injection configuration. The drive ram motion control logic (136) may utilize both a target pressure and a monitored pressure to derive a velocity for advancing a drive ram. The pressure monitoring logic (138) may provide a monitored pressure value for the drive ram control logic (136), where this monitored pressure value may be derived from the input power being used to advance a drive ram and the drive ram velocity.

Abstract:
An apparatus for use in electrostatically applying coating material to an object includes a nozzle (21) which directs a flow of coating material toward the object (28). A power supply unit (9) provides an electric field to electrostatically charge the coating material. Control circuitry (16) is provided to monitor the operating efficiency of the power supply unit (9) and to provide an output signal when there is an impending failure of the power supply unit (9). The control circuitry monitors the relationship between an input current to the power supply unit (9) and an output current from the power supply unit (9). When the relationship between the input current to the power supply unit (9) and the output current from the power supply unit (9) is outside of a predetermined range, the control circuitry is effective to provide an output signal to notify an operator that there is an impending power supply unit failure.
