| 20090299675 | LED CONTROL UTILIZING AMBIENT LIGHT OR SIGNAL QUALITY - A system and method for controlling a light emitting device for an optical sensor based on signal quality and/or power consumption requirements. Drive current and/or integration time is controlled as a function of detected ambient light or signal quality. As the signal quality decreases the drive current or integration time can be adjusted to provide a more usable signal. If after some criteria for reduction, such as “time on” or high signal quality, then the drive current can be decreased. | 12-03-2009 |

| 20090043180 | SENSOR AND SYSTEM PROVIDING PHYSIOLOGIC DATA AND BIOMETRIC IDENTIFICATION - A device and method of use combining a non-invasive sensor for measuring a physiologic attribute with a biometric identification means. One embodiment of the device and method includes a sensor that has incorporated therein both an oximeter and a fingerprint sensor. The sensor may be connected to a controller including a fingerprint identification circuit in addition to the oximeter circuit and other physiological circuitries such as ECG, pulse or heart rate, NIBP (Non-Invasive Blood Pressure) and temperature. A display may provide an indication of the measured blood oxygen saturation level along with identification information. The display may be located to provide remote monitoring of oxygen saturation and fingerprint identification of the patient, for example, at a central station. The fingerprint identification circuit may be activated individually to obtain the patient fingerprint, which may be recorded in a memory, either in the controller or a remote memory store, or both. | 02-12-2009 |
| 20080221420 | Fetal Pulse Oximetry and ECG Sensor - A medical device configured to be temporarily secured at a tissue field, such as a fetal skull, via a spiral probe. The spiral probe functions to both secure the sensor in place and provide an electrode for ECG purposes. The spiral probe is non-uniform and includes one or more of a stop element, a cross bar element and a collapsed portion adapted to engage tissue after a predetermined rotation of the probe into the tissue field. The probe diameter can expand with an increase in torque applied to a drive rod, leading to disengagement of the drive rod from the probe. The spiral probe and drive rod may define a detent mechanism whereby upon reaching a predetermined torque the drive rod is disengaged from the probe and freely rotates without further entry of the spiral probe into the tissue field. | 09-11-2008 |
| 20080208023 | FOLDABLE SENSOR DEVICE AND METHOD OF USING SAME - A physiologic sensor device configured to be placed on an appendage.
