Abstract: A novel and useful system wiring apparatus and related techniques that address the need to feed power and electronic signals to and from a sample board between the cold, low pressure region in a vacuum chamber and outside room temperature and atmospheric pressure. The wiring apparatus balances electrical resistance with the thermal conductivity of the power and signal conductors. Printed flexible cables are used having an annular sealing region which together with O-rings provide vacuum sealing while allowing electrical signals to pass between integrated circuit(s) inside the vacuum chamber and equipment outside the chamber. A thermal anchor is placed along the printed flexible cable to maintain a desired temperature along the cable. The printed flexible circuits are multilayer with two outer layers serving as an RF shield while two inner layers comprise the signal lines which typically require shielding, electrical isolation from each other and from external electromagnetic fields.

Abstract: Method and systems control a rotational speed of a blood pump during ventricular diastole. A method includes controlling a blood pump in accordance with a first segment operational mode. A controller monitors the blood flow rate through the blood pump. The controller determines, based on the blood flow rate, whether continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than a target minimum blood flow rate. In response to a determination that continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than the target minimum blood flow rate, the controller controls the rotational speed of the blood pump so that the blood flow rate through the blood pump is approximate to the target minimum blood flow rate.
