20100219757 | Method and Apparatus of Providing Power to Ignite and Sustain a Plasma in a Reactive Gas Generator - Described are methods and apparatuses, including computer program products, for igniting and/or sustaining a plasma in a reactive gas generator. Power is provided from an ignition power supply to a plasma ignition circuit. A pre-ignition signal of the plasma ignition circuit is measured. The power provided to the plasma ignition circuit is adjusted based on the measured pre-ignition signal and an adjustable pre-ignition control signal. The adjustable pre-ignition control signal is adjusted after a period of time has elapsed. | 09-02-2010 |
20100327927 | METHOD AND SYSTEM FOR CONTROLLING RADIO FREQUENCY POWER - A method for controlling pulsed power that includes measuring a first pulse of power from a power amplifier to obtain data. The method also includes generating a first signal to adjust a second pulse of delivered power, the first signal correlated to the data to minimize a power difference between a power set point and a substantially stable portion of the second pulse. The method also includes generating a second signal to adjust the second pulse of delivered power, the second signal correlated to the data to minimize an amplitude difference between a peak of the second pulse and the substantially stable portion of the second pulse. | 12-30-2010 |
20140148757 | FLUID CONTROL SYSTEM AND DISPOSABLE ASSEMBLY - A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly. The variable flow resistor is adjustable by the drive mechanism to achieve a target flow rate when the first calculated flow rate and/or the second calculated flow rate differs from the target flow rate. | 05-29-2014 |
20140216560 | FLUID FLOW MEASUREMENT AND CONTROL - In accordance with one embodiment, a controller in a fluid delivery system controls magnitudes of pressure in a first volume and a second volume. The first volume is of a known magnitude. The second volume is of an unknown magnitude and varies. The controller estimates a temperature of gas in the first volume and a temperature of gas in the second volume based on measurements of pressure in the first volume and measurements of pressure in the second volume. The controller then calculates a magnitude of the second volume based on measured pressures of the gases and estimated temperatures of gases in the first volume and the second volume. | 08-07-2014 |
20140221959 | AUTOMATED PROGRAMMING OF INFUSION THERAPY - An infusion management system includes an infusion management server configured for providing an order to an infusion device to administer an infusion and the infusion device. The infusion device may be configured for receiving the order, associating the order with a patient, and adjusting at least one setting according to the order. A method for administering an infusion, an interface for an infusion device and a computer program product are also disclosed. | 08-07-2014 |
20140222450 | MEDICAL DEVICE MANAGEMENT USING ASSOCIATIONS - Via communications with an association management resource, an operator of a respective fluid delivery system can associate a medical device (fluid pump) with a particular entity such as a patient, location, one or more other medical devices, the caregiver, etc. Thereafter, the operator of the fluid delivery system is able to better manage use of the fluid delivery system based on relevant medical information, which is accessible as a result of creating the association. For example, the association management resource gathers and stores information associated with the entity prior to the operator providing the input associating the fluid delivery system with the entity. After the operator of the fluid delivery system creates the association, the medical information associated with the entity is immediately available to the fluid delivery system and/or corresponding operator of the fluid delivery system. | 08-07-2014 |

The method also includes generating a first signal to adjust a second pulse of delivered power, the first signal correlated to the data to minimize a power difference between a power set point and a substantially stable portion of the second pulse. The method also includes generating a second signal to adjust the second pulse of delivered power, the second signal correlated to the data to minimize an amplitude difference between a peak of the second pulse and the substantially stable portion of the second pulse. | 10-16-2014 |
20140309617 | FLUID FLOW MEASUREMENT AND CONTROL - In accordance with another embodiment, a controller in a fluid delivery system initiates drawing fluid into a chamber of a diaphragm pump. During a delivery phase of pumping the fluid in the chamber to a target recipient, the controller applies pressure to the chamber. At multiple different times during the delivery phase, the controller temporarily discontinues application of the pressure to the chamber to calculate how much of the fluid in the chamber has been pumped to the target recipient. | 10-16-2014 |
20150088094 | MEDICAL DEVICE MANAGEMENT USING SAFETY SUPERVISOR - A fluid flow manager executing on first hardware controls a flow of fluid outputted from a fluid delivery pump to a recipient. A monitor resource, executing on second hardware operating independently of the first hardware, monitors for an occurrence of a failure condition associated with the delivery of fluid. In response to detecting occurrence of a failure condition associated with delivery of the fluid, the monitor resource generates a control output. The control output can be used to perform operations such as discontinue delivery of the fluid, notify a respective caregiver of the delivery failure, etc. | 03-26-2015 |
