Title: Apparatus and method for measuring an induced perturbation to determine physiological parameter
Inventor: CARO RICHARD G
IPC: A61B5/022
Filed: 1995-04-03
Granted: 2000-02-29
Abstract: A monitor for continuously determining a patient's physiological parameter includes a means for obtaining a periodic calibration measurement of the patient's physiological parameter. An exciter, positioned over an artery of the patient induces an exciter waveform into the patient's arterial blood. A noninvasive sensor, positioned over the artery, senses a hemoparameter and provides a noninvasive sensor signal output representative of the hemoparameter. A processor receives the calibration measurement and noninvasive sensor signal output. The processor determines a DC offset based on the calibration measurement and processes the noninvasive sensor signal to continuously determine the patient's physiological parameter. A method includes steps for performing the present invention. In the preferred embodiment, the physiological parameter measured is blood pressure, however, the present invention can also be used to analyze and track other physiological parameters such as vascular wall compliance, strength of ventricular contractions, vascular resistance, fluid volume, cardiac output, myocardial contractility and other related parameters.

IPC: G06F11/30
Filed: 1998-07-30
Granted: 2008-10-14
Abstract: A data processing method capable of easily assembling plural exception processing environments. In executing an application program, an object to be fed with an error message on occurrence of an exception event which is likely to cause interruption of the normal execution of the application program is previously registered. If an exception event has occurred, an exception occurrence message indicating occurrence of the exception event is sent to a pre-set object. The object, thus fed with the exception occurrence message, generates an error message corresponding to the exception event indicated by the exception occurrence message and sends the generated error message to the registered object. This object sends a message commanding execution of a pre-set processing corresponding to the error message to the application program responsible for the exception event.

Granted: 2005-07-05
Abstract: A variable valve timing system applicable for vary the opening and closing cycle of the inlet and outlet valves of an internal combustion engine. The system comprises a cam follower (4) and a cam (1) which is rotated about the cam shaft (3) to move the valve between its open and closed position. To vary the cycle of the opening and closing of the valves, a rotational means (11 and 12) is connected to the cam follower (4) to rotate the cam follower (4) such that the cam follower (4) and cam (1) are out of alignment such that the cam lobe engages the contact surface (2) at a higher point and hence earlier than if the cam follower (4) and the cam (1) are aligned. Therefore the valve is opened sooner and closed later, increasing the degrees of cycle for which the valve is open, for example, as the engine revolutions increase.
