    摘要: A method for measuring blood pressure during a limited number of blood pressure cycles at an area overlying an artery of a living subject, includes applying a pressure (P) to the artery for occluding the artery in response to a pressure signal. Subsequently the pressure is released to re-open the artery in response to a pressure release signal. A delay time is computed, by comparing a first time duration with a second time duration. The delay time is from a reference point in time after which a next pressure release signal is to be supplied to a device for applying a pressure. A pressure to be applied to the artery in a next measuring cycle is computed. Subsequently a pressure signal and a pressure release signal corresponding to the computed pressure and delay time are supplied to the device for applying a pressure.

    摘要: Operation of a patient's heart or lungs may be analyzed by transmitting ultrasound energy into the patient's lung, and detecting Doppler shifts of reflected ultrasound induced by moving borders between blood vessels in the lung and air filled alveoli that surround the blood vessels. Movement of the border is caused by pressure waves in the blood vessels that result in changes in diameter of those blood vessels. The detected Doppler shifts are processed with an algorithm designed to increase signal from the moving border with respect to other reflected ultrasound signals and the results are then displayed.

    摘要: A humidifier uses a field of hydrophobic, nanotubes (e.g., vertically aligned carbon nanotubes) to humidify a gas. Voids in the field form liquid flow channels that are wide enough for liquid water to pass through. The nanotubes are spaced close enough to each other to prevent the water from escaping the channels. Water in the channels is absorbed by gas that flows and/or diffuses between the nanotubes. Humidity levels in the gas can be measured and controlled to a desired level by controlling the rate of flow of gas through the humidifier, controlling heating of the gas, and/or adjusting the total area of molecular transfer from the water to the gas by providing multiple banks of nanotubes and controlling the number of banks through which the gas flows.

    摘要: An implantable device that (a) has an analog input configured to detect analog electrical signals and (b) is configured to accept RF commands can be retrofitted to prevent unauthorized access by modifying the software of the implantable device to (1) accept control commands that arrive via the analog input and (2) ignore control commands that arrive via the RF transceiver. Ultrasound communications can then be detected and inductively coupled onto a lead that is connected to the analog input. In some embodiments, the modified implantable device can only be controlled via ultrasound signals at all times to improve security. In other embodiments, the modified implantable device can only be controlled via non-ultrasound signals (e.g., RF signals) for short periods of time after the system has been unlocked in response to receipt of a specific ultrasound signal.

    摘要: Blood or other fluids can be caused to interact with a gas by providing a plurality of fluid flow channels that are surrounded by nanotubes, each of the channels having an inflow end and an outflow end, wherein each of the channels is wide enough for the blood to flow through, and wherein the nanotubes are spaced close enough to each other to retain the fluid within the channels when the blood is flowing through the channels. The fluid is then passed through the through the channels while a gas is passed through the spaces between the nanotubes outside the fluid flow channels. This permits the gas to interact with the fluid in the channels.

    摘要: An apparatus, method and system for detecting a position within a body are provided. A dipole that is free to rotate or oscillate within a capsule is inserted at a target location within the body. The dipole can be either electric or magnetic, and the dipole rotates or oscillates within the capsule when an alternating or rotating electric or magnetic field is applied in the vicinity of the dipole. Ultrasound energy is impinged upon the target location and a position of the dipole is determined based on detected ultrasound reflections.
