20110094619 | SYSTEM FOR DISPENSING A FLUID IN NON-CONTROLLED ENVIRONMENTS - The present invention provides a dispenser cassette ( | 04-28-2011 |
20130225903 | PIERCE AND FILL DEVICE - A pierce and fill connector cap for a vial sealed by an elastomeric septum includes a vial collar and a needle holder. The vial collar body defines a collar aperture to be positioned in overlying registry with the septum of the vial, and the needle holder includes a needle holder body providing a means for holding an elongate needle in registry with the collar aperture. The needle holder body being moveable with respect to said vial collar between a first position spaced from the vial collar and a second position proximate the vial collar, such that a needle held by the needle holder will puncture through the vial septum. | 08-29-2013 |
20130337493 | QUALITY CONTRL DEVICES AND METHODS FOR RADIOPHARMACEUTICALS - A quality control (“QC”) system for PET or SPECT radiopharmaceuticals is disclosed that contains a disposable, no-leakage, self-contained QC cassette, which interfaces with the QC system. The QC system may include a shield that substantially surrounds the cassette such that the area and the cassette are both shielded. The QC cassette may contain shielding also. The QC cassette contains components for conducting one or more QC tests. These components include sensor and devices for performing various QC tests on radiopharmaceuticals. The QC system may contain a number of sub-systems and devices for supporting the QC tests. The QC system may produce a QC report containing the test results. | 12-19-2013 |

20090182237 | Dual Frequency Band Ultrasound Transducer Arrays - An acoustic probe transmits/receives acoustic pulses with frequencies both in a high frequency (HF), and a selectable amount of lower frequency (LF1, LF2, . . . , LFn, . . . ) bands. The radiation surfaces of at least two of the multiple frequency bands have a common region. The arrays and elements can be of a general type such as annular arrays, phased or switched arrays, linear arrays with division in both azimuth and elevation direction, like a 1.5D, a 1.75D and a full 2D array, or curved arrays. The element division, array type, and array aperture sizes for the different bands can also be different. | 07-16-2009 |

20100036244 | Nonlinear Elastic Wave Measurement and Imaging with Two-Frequency Elastic Wave Pulse Complexes - Methods and instruments for suppression of multiple scattering noise and extraction of nonlinear scattering components with measurement or imaging of a region of an object with elastic waves, where elastic wave pulse complexes are transmitted towards said region where said pulse complexes are composed of a high frequency (HF) and a low frequency (LF) pulse with the same or overlapping beam directions and where the HF pulse is so close to the LF pulse that it observes the modification of the object by the LF pulse at least for a part of the image depth. The frequency and/or amplitude and/or phase of said LF pulse relative to said HF pulse varies for transmitted pulse complexes in order to nonlinearly manipulate the object elasticity observed by the HF pulse along at least parts of its propagation, and where received HF signals are picked up by transducers from one or both of scattered and transmitted components of the transmitted HF pulses. Said received HF signals are processed to form measurement or image signals for display, and where in the process of forming said measurement or image signals said received HF signals are one or both of delay corrected with correction delay in the fast time (depth-time), and pulse distortion corrected in the fast time, and combined in slow time to form noise suppressed HF signals or nonlinear scattering HF signals that are used for further processing to form measurement or image signals. The methods are applicable to elastic waves where the material elasticity is nonlinear in relation to the material deformation. | 02-11-2010 |
20140150556 | Measurement and Imaging of Scatterers with Memory of Scatterer Parameters Using at Least Two-Frequency Elastic Wave Pulse Complexes - Measurement or imaging of elastic wave nonlinear scatterers with a memory of scattering parameters comprises selecting LF pulses having characteristics to change the scattering parameters of nonlinear scatterers. A transmit time relation is selected so that the incident HF pulse propagates sufficiently close to the LF pulse that the effect of the incident LF pulse on its scatterer parameters is observed by the HF pulse. At least two elastic wave pulse complexes comprising a high frequency (HF) pulse and a selected low frequency (LF) pulse are transmitted towards the region. Received HF signals are combined to form nonlinear HF signals representing the scatterers with memory, with suppression of received HF signals from other scatterers. At least one of the received HF signals may be corrected by time delay correction and/or speckle correction with a speckle correction filter, determined by movement of the scattering object. Systems are also disclosed. | 06-05-2014 |
