20100081901 | Medical Sensor And Technique For Using The Same - According to embodiments, sensors and systems for medical spectroscopy may include adaptive optical components, such as digital light processing components. Adaptive light emitting elements may allow such sensors to alter the intensity profile of emitted light photons to change the distribution of photons through the tissue or to scan areas of tissue to determine if certain areas may be associated with improved measurements. In addition, sensors with adaptive light detecting elements as provided may adapt to selectively detect light of certain wavelengths or from certain regions of the tissue. | 04-01-2010 |

20110083509 | Photoacoustic Spectroscopy With Focused Light - Photoacoustic measurements utilize emitted light to generate an acoustic response in tissue, with the acoustic response being proportional to the presence of an absorber of the light in the tissue. The present disclosure relates the use of focused light to acquire photoacoustic measurements. In one embodiment, the light is modulated, such as spatially modulated, such that the light may be focused within an otherwise scattering medium, such as tissue. | 04-14-2011 |
20110208010 | MOTION ENERGY HARVESTING WITH WIRELESS SENSORS - A system and method for generating power when one or more motion sensitive structures are moved. The system may include one or more sensing components which, acting alone or in combination, are capable of generating data related to one or more physiological parameters. The system may also include wireless communication circuitry capable of wirelessly transmitting the data related to the one or more physiological parameters. Furthermore, at least one of the one or more sensing components or the wireless communication circuitry may be at least partially powered, directly or indirectly, by the one or more motion sensitive structures. | 08-25-2011 |
20120273548 | DEVICE FOR MONITORING PHYSIOLOGICAL PARAMETERS IN VIVO - A monitoring system is disclosed for in vivo monitoring of preselected physiological parameters associated with acute and/or chronic tissue compromise or failure in one or multiple tissue/organ sites in real time. In one method, a body portion of a surgical stapling device is positioned adjacent a first tissue section, an anvil assembly adapted to engage the body portion is positioned adjacent a second tissue section, and a monitoring device is positioned adjacent the first and/or second tissue sections. The monitoring device includes a sensor adapted to measure a preselected physiological parameter and a transmitter for transmitting signal to an extracorporeal receiving unit. The surgical stapling device is fired to mechanically secure the first and second tissue sections with at least one staple and the preselected physiological parameter is monitored via the information transmitted from the monitoring device to the receiving unit. | 11-01-2012 |
