20110137185 | Saddle Faced Small Animal Sensor Clip - A noninvasive photoplethysmographic sensor platform for small animals provides a spring biased sensor clip, wherein at least one side of the sensor clip is provided with a saddle faced clip face member. The saddle shape of the clip face member may have a hinge end, toward the hinge of the clip, which is longer in the longitudinal direction of the clip and shorter in depth than the distal end. The shorter distal end side (measured longitudinally) of this saddle shape facilitates the ability to align the transmitted and received light with the bone, while the overall saddle shape of the facing provides a physical grip to capture enough tissue to prevent the clip from relocating over time while it is attached to the limb. The shorter hinge end side (depth-wise) also allows the clip to close when it is fully assembled. The edges of the saddle shaped clip are preferably rounded off to prevent the contusions of the tissue that may result from long-term contact. This saddle faced feature works well on only one side of the clip. | 06-09-2011 |

20140276120 | APPARATUS AND METHOD FOR MONITORING PRESSURE RELATED CHANGES IN THE EXTRA-THORACIC ARTERIAL CIRCULATORY SYSTEM - A method and apparatus for monitoring changes in the intra-thoracic pressure of a patient due to the patient's respiratory activity or volumetric changes in the extra-thoracic arterial circulatory system due to cardiac function based on the changes in pressure in the patient's extra-thoracic arterial circulatory system as measured by a plethysmography sensor, such as an photoplethysmograph. A frequency spectrum is generated for the plethysmograph signal and the frequencies of interest is isolated from the frequency spectrum by setting appropriate cutoff frequencies for the frequency spectrum. This isolated frequency is used to filter the plethysmograph signal to provide a signal indicative of the patient's respiratory activity or cardiac function. | 09-18-2014 |
