    摘要： An enhanced pressure sensing system and method use an external diaphragm to address issues involved with accurate and prolonged measurement of fluid pressure, such as of blood flowing in a vascular structure. Some external diaphragms include a metallized layer or other highly impermeable layer to furnish a high degree of seal at least near to hermetic grade. As temperature of the intermediary fluid changes, the external diaphragm is able to move in a direction that minimizes differential pressure across the external diaphragm over an operational temperature range thereby reducing pressure change of the intermediary fluid due to change in temperature of the intermediary fluid. Relatively smooth hydrodynamic surfaces can be used as well as a bi-layer construction.

    摘要： An enhanced intraluminal flow measurement system and method is conducive for a low-power ultrasonic system that can use continuous-wave (CW) Doppler sensing and wireless RF telemetry. Applications include measurement of blood flow in situ in living organisms. Implementations include an extraluminal component located outside of a body, such as a human or animal body, containing a lumen. The extraluminal component can be wirelessly coupled via an RF magnetic field or other RF field to an implantable intraluminal component. The intraluminal component (i.e. implant) is implanted inside of the lumen of the body such as a heart or elsewhere in a vasculature (such as in a dialysis shunt). The intraluminal component can telemeter, via RF electromagnetic signals, flow data directly out of the body housing the intraluminal component to be received by the extraluminal component.

    摘要： As described herein vascular anchoring systems are used to position an implant in a vascular area such as a bifurcated vasculature with relatively high fluid flow, for instance, in an area of a pulmonary artery with associated left and right pulmonary arteries. Implementations include an anchoring trunk member having a first anchoring trunk section and a second anchoring trunk section. Further implementations include a first anchoring branch member extending from the anchoring trunk member. Still further implementations include a second anchoring branch member extending from the anchoring trunk member.

    摘要： Electronic devices and accessories such as headsets for electronic devices are provided. A microphone may be included in an accessory to capture sound for an associated electronic device. Buttons and other user interfaces may be included in the accessories. An accessory may have an audio plug that connects to a mating audio jack in an electronic device, thereby establishing a wired communications link between the accessory and the electronic device. The electronic device may include power supply circuitry for applying bias voltages to the accessory. The bias voltages may bias a microphone and may adjust settings in the accessory such as settings related to operating modes. User input information may be conveyed between the accessory and the electronic device using ultrasonic tone transmission. The electronic device may also gather input from the accessory using a voltage detector coupled to lines in the communications path.
