"It is my heart-warmed and world-embracing Christmas hope and aspiration that all of us, the high, the low, the rich, the poor, the admired, the despised, the loved, the hated, the civilized, the savage (every man and brother of us all throughout the whole earth), may eventually be gathered together in a heaven of everlasting rest and peace and bliss, except the inventor of the telephone. "
Mark Twain ; Christmas greetings, 1890

| Number | Title | Issue Date |
| 6045509 | Apparatus and method for measuring an induced perturbation to determine a physiological parameter A monitor for determining a patient's physiological parameter includes a calibration device configured to provide a calibration signal representative of the patient's physiological parameter. An exciter is positioned over a blood vessel of the patient for... | 04/04/2000 |
| 6027452 | Rapid non-invasive blood pressure measuring device A blood pressure can be obtained by supplying an external pressure to a portion of an artery. The external pressure is preferably between the systolic and diastolic pressure. An event which occurs at least once a cycle can then be identified. This event c... | 02/22/2000 |
| 5904654 | Exciter-detector unit for measuring physiological parameters An exciter-detector unit is disclosed which includes an exciter and a detector mounted on a common support for inducing perturbations into the body and detecting the perturbations after they travel a distance through the body in order to detect a hemopara... | 05/18/1999 |
| 5833618 | Apparatus and method for measuring an induced perturbation to determine a physiological parameter A monitor for determining a patient's physiological parameter includes a calibration device configured to provide a calibration signal representative of the patient's physiological parameter. An exciter is positioned over a blood vessel of the patient for... | 11/10/1998 |
| 5830131 | Apparatus and method for measuring an induced perturbation to determine a physical condition of the human arterial system A monitor for determining a patient's physical condition includes a calibration device configured to provide a calibration signal representative of a patient's physiological parameter. An exciter is positioned over a blood vessel of the patient for induci... | 11/03/1998 |
| 5810734 | Apparatus and method for measuring an induced perturbation to determine a physiological parameter A monitor for determining a patient's physiological parameter includes a calibration device configured to provide a calibration signal representative of the patient's physiological parameter.

| 5791347 | Motion insensitive pulse detector A motion insensitive pulse detector for detecting a patient's pulse includes an exciter adapted to be positioned over a blood vessel of the patient and configured to induce a transmitted exciter waveform into the patient. A noninvasive sensor is adapted t... | 08/11/1998 |
| 5785659 | Automatically activated blood pressure measurement device A monitor for activating a sphygmomanometer attached to a patient includes a sensor attached to the patient to generate a sensor signal representative of a physiological parameter. This sensor can be, for example, a noninvasive sensor that generates a sig... | 07/28/1998 |
| 5590649 | Apparatus and method for measuring an induced perturbation to determine blood pressure 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 ... | 01/07/1997 |
