20140176175 | Dry Catheter RF Tester - A method and a system of testing an electrical signal path functionality of a sensing catheter in a dry environment. A variety of test input patterns are generated by an arbitrary near field RF signal generator, transmitted into the sensing catheter disposed in a shielded enclosure. B-mode like images corresponding to the test input patterns are generated and displayed by an imaging system connected to a proximal end of the sensing catheter, and then analyzed by a computer system, as dependent on the frequency, amplitude, and phase of the test input patterns. A determination is made as to whether the sensing catheter retains a desired electrical signal path functionality based on the analysis. The sensing catheter could be a variety of sensing catheters including forward looking catheters, a rotational IVUS catheters, or phased array IVUS catheters. | 06-26-2014 |
20140180079 | Guarded Imaging Devices and Methods - An integrated therapeutic and imaging device that uses at least two balloons to provide a guarded zone that can be evacuated and replaced with a fluid that is sufficiently clear to permit optical coherence tomography (or even high resolution ultrasound) imaging that would otherwise be of poor quality or impossible. Methods of making and operating the imaging device to obtain clear, high quality images, as well as treating a patient's tissue with the device within a living body in association with obtaining an image of the patient's tissue, are included. | 06-26-2014 |

20120179944 | DENSE REGISTER ARRAY FOR ENABLING SCAN OUT OBSERVATION OF BOTH L1 AND L2 LATCHES - A scannable register array structure includes a plurality of individual latches, each configured to hold one bit of array data in a normal mode of operation. The plurality of individual latches operate in scannable latch pairs in a test mode of operation, with first latches of the scannable latch pairs comprising L1 latches and second latches of the scannable latch pairs comprising L2 latches. A test clock signal generates a first clock pulse signal, A, for the L1 latches and a second clock pulse signal, B, for the L2 latches. The L2 latches are further configured to selectively receive L1 data therein upon a separate activation of the B clock signal, independent of the test clock signal, such that a scan out operation of the individual latches results in observation of L1 latch data. | 07-12-2012 |

20090011628 | Self-Muting audio connector - This disclosure concerns methods, systems and apparatus that can be automatically activated by means of insertion into a jack socket and designed such that when inserted, no longitudinal force is exerted on the jack. In particular, self-muting connectors employ a spring-biased switch with an internal spring and a protrusion. When the connector is disconnected, the protrusion extends outwardly of a ground sleeve and the spring contacts an inner signal conductor. In this state, the switch shorts the signal conductor and ground sleeve together. When the connector is inserted into a complementary jack socket, the protrusion is urged inwardly and the spring deformed such that it ceases to contact the inner conductor, thereby the breaking the short-circuit between the signal conductor and ground sleeve. This allows a normal electrical connection to be established between the connector and the device to which the connector is inserted. | 01-08-2009 |
