摘要:
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.

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.

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.
摘要:
A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.

A remote control device that provides a wireless connection between the operator and a control console of a material coating spraying system, thereby allowing the operator to select, change, modify and otherwise control a variety of parameters and functions of the spraying operation. The remote capability permits an operator to be stationed at, in or near the spray booth so as to be able to observe the actual spraying operation and transmit instructions to the control console. In one embodiment, a powder spray system includes a spray gun having a pressurized air inlet and a powder inlet, a powder spray booth, a powder supply for feeding powder to the gun, a control console separately located with respect to the booth; the console being operable to control a spraying operation; and a hand-held remote control device for wireless operation of the control console by an operator positioned a distance from the console.
摘要:
A powder spray coating system includes a power source and an electrical supply line connected to the power source. A spray gun sprays powder in a spray pattern onto a part. The spray gun includes an electrode which charges powder as the powder is dispensed from the gun toward the part. The electrode is connected to the electrical supply line. A first current sensing device is located in the electrical supply line measuring gun current between the power source and the electrode. An ion collector or ABI probe is mounted with the gun for collecting free ions produced by the electrode. The collector has a forward portion positioned near the spray pattern and is spaced from the electrode. The collector is connected to a ground line. A second current sensing device is located in the ground line measuring back current between the ion collector and ground. A controller is connected between the power source and the electrode to control the gun current. The controller is also connected to the first and second current sensing devices for controlling the gun current in accordance with the difference between the measured gun current and the back current. By automatically controlling the current between the gun and the part, the present invention controls the field strength and the current between the tip of the gun and the ABI probe, making unnecessary adjustment of the position of the ABI probe in order to maximize the benefits of the probe in situations where the distance between the gun and the part changes.
