摘要： A parameter sensor including a conduit configured to contain a material is controlled. A first excitation applied to the conduit is determined. Motion of the conduit in response to the first excitation is determined. A second excitation to apply to the conduit is determined from the determined first excitation, the determined motion in response to the first excitation, a desired motion for the conduit, and a frequency response for the conduit. In particular, excitations may be iteratively determined and applied to the conduit, and motion signals representing motion of the excited conduit may be processed to generate process parameter estimates, such as mass flow rate estimates. The frequency response may be assumed to be time-invariant, or may be adaptively estimated. The invention may be embodied as methods, apparatus and computer program products.

摘要： An apparatus for assisting cardiac function of a patient includes an inflatable chamber operably positionable with respect to an aorta of the patient, a percutaneous access device implantable with respect to a hypogastric region of the patient and connectible in fluid communication with the inflatable chamber, and a drive unit connectible through the percutaneous access device for selectively inflating and deflating the inflatable chamber in accordance with a control program stored in memory. The control program controls the drive unit in response to a periodically scheduled patient monitoring routine for measuring values of the physiology of the patient. The control program uses measured values as modified in accordance with the control program and physician programmable parameters for assisting cardiac function of the patient. The program includes the steps of automatically controlling the drive unit in response to a periodically scheduled patient monitoring routine for measuring values of physiology of the patient, and using measured values as modified in accordance with physician programmable parameters for assisting cardiac function of the patient. A software program is connectible in electronic communication with the control program for adjusting settings of the drive unit. The software program is capable of one or more of the following functions: retrieving current values of physician programmable parameters, selectively retrieving a history of the drive unit operation including error detection records, displaying a continuous ECG, and/or displaying a single-beat sample of aortic pressure waveform obtained in real time from the patient.

摘要： A pressure measuring system has a line through which a fluid (4) flows, the line (3) having a central line section (5) in which, on a flattened outer side (6) of the line (3), a diaphragm is provided. The movements of the diaphragm, which are characteristic of pressure changes, are transmitted to a pressure sensor. In this case, the diaphragm is nondetachably connected to a protrusion (10) which points away from the line (3) and has an extension (12) which is oriented substantially transversely with respect to the longitudinal alignment of the line section (5) and, in a mechanical and simultaneously detachable way, acts on a force sensor as pressure sensor. A pressure measuring system is therefore provided which can be used for reconditioning in the autoclave sterilizer.

The pulled-up pads and the power supply pad are electrically connected to a power supply terminal outside the chip via the internal exposed portions, the wires, and a power-supply-connecting external wire. Terminals may be electrically connected together on a package or a mounting substrate.
