20140083959 | MERCHANDISING DISPLAY DEVICE - A merchandise display device includes a rear cross-bar, first and second side arms, a locking pin, and a front cross-bar that is interoperable with the locking pin to secure merchandise on the display device and to secure the display device to a vertical support member. The locking pin is carried by a side arm and movable between an extended position and a retracted position. When occupying the extended position, the locking pin is adapted to engage the vertical support member to secure the merchandise display device thereto. The front cross-bar is mounted to the first and second side arms and is movable between a locked position, engaging the locking pin to prevent the locking pin from being moved out of the extended position, and an unlocked position, spaced away from the locking pin to allow movement of the locking pin out of the extended position toward the retracted position. | 03-27-2014 |

20100030073 | MODELING OF PHARMACEUTICAL PROPAGATION - A method of delivering a contrast enhancing fluid to a patient using an injector system, including: determining at least one patient transfer function for the patient based upon data specific to the patient and, the at least one patient transfer function providing a time enhancement output for a given input; determining a desired time enhancement output; using the at least one patient transfer function to determine an injection procedure input; and controlling the injector system at least in part on the basis of the determined injection procedure input. The injection procedure input can determined considering at least one operational limitation or constraint of the injector system. A method of modeling propagation of a pharmaceutical fluid in a patient, includes: collecting data corresponding to a time response curve resulting from injection of the fluid; and determining at least one mathematical model describing the data. The mathematical model can, for example, be a model which is not determined by a continuous or a discrete-time Fourier deconvolution of the data. A method of controlling injection of a pharmaceutical fluid into a patient using an injector in a medical procedure, includes: collecting data corresponding to a patient response curve resulting from injection of the fluid; determining at least one mathematical model describing the data; and controlling the injector during the medical procedure to control injection of the fluid into the patient to create patient response at least in part on the basis of the mathematical model. A method of controlling injection of a contrast medium into a patient using an injector in a medical imaging procedure using an imaging scanner, includes: determining at least one mathematical model to predict a time enhancement response resulting from injection of the contrast medium; determining an injection protocol to approximate a predetermined time enhancement response in the patient by determining a constrained input solution to the mathematical model; and using the injection protocol to control the injector during the medical imaging procedure to control injection of the contrast medium into the patient to create an image of a region of interest. Patient transfer functions for the patient of the present invention can also be based at least in part on a measurement of cardiac output of the patient. Likewise, mathematical models of the present invention can be based at least in part on a measurement of cardiac output of the patient. | 02-04-2010 |
20100113887 | PATIENT-BASED PARAMETER GENERATION SYSTEMS FOR MEDICAL INJECTION PROCEDURES - A system includes a parameter generation system to determine parameters of at least one phase of an injection procedure based at least in part upon a type of the injection procedure. The parameter generator system determines the amount of a pharmaceutical that is to be delivered to a patient at least in part on the basis of the concentration of an agent in the pharmaceutical and at least on part on the basis of a function that depends upon and varies with a patient parameter. The patient parameter can, for example, be weight, body mass index, body surface area or cardiac output. The pharmaceutical can, for example, include a contrast enhancing agent for use in an imaging procedure. | 05-06-2010 |
20110178359 | Systems For Integrated Radiopharmaceutical Generation, Preparation, Transportation and Administration - An integrated radiopharmaceutical patient treatment system is disclosed including a patient support platform with an associated patient stimulus apparatus, an imager proximate the patient support platform, a radiopharmaceutical fluid delivery system for infusing a radiopharmaceutical fluid into a patient, a patient monitor to be associated with a patient, and an integrated system controller operably associated with the patient stimulus apparatus, imager, radiopharmaceutical fluid delivery system, and patient monitor to control and coordinate their operations. Within the patient treatment system the radiopharmaceutical fluid delivery system may be included comprising a radionuclide supply module, a radiopharmaceutical processing module, a quality control module, a patient injection module, and a controller. A hazardous fluid handling system including a docking station and a hazardous fluid transport device adapted to detachably dock with the docking station is further disclosed. | 07-21-2011 |

20130253314 | DEVICES AND SYSTEMS FOR DETERMINATION OF PARAMETERS FOR A PROCEDURE, FOR ESTIMATION OF CARDIOPULMONARY FUNCTION AND FOR FLUID DELIVERY - A method of determining at least one parameter for an imaging procedure including the injection of a contrast enhancement fluid which includes a contrast enhancing agent, includes: substituting into a model discrete point data determined from at least one contrast time enhancement curve measured using an imaging system for a first region of interest resulting from injection of a bolus of the contrast enhancement fluid. In several embodiments, a sufficient number of data points can be substituted into the model to determine values for physiological variables in the model. The variables can, for example, be related to cardiopulmonary function. At least one data point from at least a second contrast time enhancement curve for a second region of interest measured using the imaging system can also substituted into the model. | 09-26-2013 |

20120110158 | FIELD PANEL WITH EMBEDDED WEBSERVER AND METHOD OF ACCESSING THE SAME - The systems, methods and devices disclosed herein provide for a field panel that includes a webserver. The field panel and webserver are arranged in communication with one or more automation components and/or field panels deployed for operation in connection with the building automation system. An information request may be directed to a master field panel for authorization. The master field panel may in turn query a node table containing address and/or communication information with the other field panels and/or automation components operable on the wired or wireless communication network. The information within the node table allows for direct communication to the other field panels and/or automation components operable on the network. In this way, authorized access to each of the field panels and/or automation components is achieved while any communications bottleneck at the master field panel may be significantly reduced or eliminated. | 05-03-2012 |
