    Abstract: Aspects of this disclosure relate to a tunable filter with tunable rejection. The tunable filter includes mutually coupled inductors and a tunable impedance circuit electrically connected to at least one of the mutually coupled inductors. The tunable impedance circuit is configured to adjust at least two notches in a frequency response of the tunable filter by changing a state of a switch. The tunable filter can filter a radio frequency signal. Related methods, radio frequency systems, radio frequency modules, and wireless communication devices are also disclosed.

    Abstract: A physiological patient monitor can include a front end conditioner that can receive analog sensor signal from a sensor responsive to a person's physiology. The patient monitor can further include an analog-to-digital converter that can convert analog sensor signal to a digital sensor information. The patient monitor can determine one or more patient specific physiological parameters. The patient monitor can further determine a physiological condition of a patient based on processing multiple physiological parameters. The patient monitor can generate a user interface that can included a visual representation of the patient's physiological condition.

    Abstract: The subject guide catheter extension system with a micro-catheter delivery catheter includes an outer sheath, an inner member extending within the sheath, and a mechanism for engagement/disengagement of the inner member to/from the sheath. Several mechanisms of engagement/disengagement between the inner and outer members are provided including a friction mechanism, threaded mechanism, pull away sheath, and engagement/disengagement mechanism for pusher's handles. The sheath and the inner member are modified for different engagement/disengagement mechanisms operation. A micro-catheter delivery system provides for an improved atraumatic crossability to the treatment site in an expedited and simplified fashion. During a procedure, a guidewire along with a guide catheter are advanced to the vicinity of the treatment site within a blood vessel. Subsequent thereto, the subject guide catheter extension system is manipulated to advance the micro-catheter along the guidewire inside the guide catheter towards and beyond the site of interest. Once the micro-catheter is in place, the outer sheath slides along the micro-catheter until reaching the lesion, and then the inner member is removed from the sheath, and the sheath then is ready for passing the treatment catheter (stent/balloon) towards the lesion to be treated.

    Abstract: Systems and methods based on thermal imaging for rapid detection of fever conditions in humans that provide for extremely inexpensive, mass producible, field deployable devices accurate in specific, relatively low temperature ranges, and in particular temperatures near nominal human body temperature. The system may include a thermal imager tailored for the application and a corresponding mass producible controlled temperature calibration source configured to provide real time calibration near the human body temperature of interest. The imager and source are deployed in a way such that target people and the calibration source will be within the imager FOV for fever detection. The combination of real time near measurement temperature calibration, with suitable thermography approaches, yield fast, accurate measurements in the fever range using low cost, easy-to-produce components. In combination with a visible imager and pattern/facial recognition techniques, detection of a human target's facial regions of interest suitable for fever detection can be accurately accomplished.
