| 20080251556 | Vehicle hitch assembly for suspension support of an accessory - A vehicle hitch assembly for suspension support of an accessory from the rear of a vehicle having a rear bumper and a trailer hitch receiver positioned under the bumper. The hitch assembly includes a horizontally extending rigid trailer hitch receiver insert for insertion and retention in the vehicle trailer hitch receiver, and a rigid support arm having one end detachably securable to the vehicle rear bumper and another end thereof rigidly securable to the trailer hitch receiver insert. An accessory support is then secured to the vehicle hitch assembly for supporting a load off of the rear of the vehicle. | 10-16-2008 |
| 20090014488 | Vehicle hitch assembly for suspension support of an accessory - A vehicle hitch assembly for suspension support of an accessory from the rear of a vehicle having a rear bumper and a trailer hitch receiver positioned under the bumper. The hitch assembly includes a horizontally extending rigid trailer hitch receiver insert for insertion and retention in the vehicle trailer hitch receiver, and a rigid support arm having one end adjustably and detachably securable to the vehicle rear bumper and another end thereof rigidly and adjustably securable to the trailer hitch receiver insert. An accessory support is then secured to the vehicle hitch assembly for supporting a load off of the rear of the vehicle. | 01-15-2009 |

| 20100222655 | 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. | 09-02-2010 |

| 20080262326 | Signal Processing Method and Apparatus for Processing a Physiologic Signal such as a Photoplethysmography Signal - A signal processing method of processing a physiologic signal, such as a Photoplethysmography Signal having at least some cardiac components and/or respirator components in the physiologic signal, the processing including the steps of: Identifying a potential cardiac and or respiratory components of a physiologic signal wherein the potential cardiac and or respiratory components have a series of peaks and valleys; Calculating a comparison of the durations of a peak to valley sub-component and a valley to peak sub component of the potential cardiac and or respiratory components; and Utilizing the calculated comparison to evaluate the potential cardiac and or respiratory components. | 10-23-2008 |
| 20100145170 | Small Animal Pulse Oximeter User Interface - A user interface for a pulse oximetry device that calculates physiologic parameters of a subject including at least a subject's heart rate and S | 06-10-2010 |
| 20100160751 | PHOTOPLETHYSMOGRAPHIC SENSOR BASED BLOOD GAS MONITOR DEVICE FOR ANALYSIS, RESEARCH AND CALIBRATION IN AN EXTRACORPOREAL CIRCUIT OR EXTRACORPOREAL PULSE SIMULATION SYSTEM - A blood oxygenation monitoring device may comprise an extracorporeal pulse simulation system including one at least partially transparent blood holding element with a photoplethysmographic sensor coupled to the element and adapted to measure particular gas content of the blood. The system includes a pulse simulation mechanism configured to simulate pulsatile behavior of the blood within the element relative to the photoplethysmographic sensors. The blood holding element may be a reservoir, wherein the pulse simulation mechanism includes a magnetic stirrer and stir bar within the reservoir. The blood holding member may be flexible tubing having blood flow there through, wherein the pulse simulation mechanism is a peristaltic pump coupled to the tubing. The monitoring device can rapidly and accurately form oxygen dissociation curves. The monitoring device can be utilized in conjunction with a heart lung bypass machine or other extra corporeal circuit devices or can be a calibration tool for sensors. | 06-24-2010 |
