20110202016 | SYSTEMS AND METHODS RELATING TO POLYMER FOAMS - Systems and methods related to polymer foams are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to a body cavity and placed in contact with, for example, tissue, injured tissue, internal organs, etc. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in situ foam formation). In addition, the foamed polymers may be capable of exerting a pressure on an internal surface of a body cavity and preventing or limiting movement of a bodily fluid (e.g., blood, etc.). | 08-18-2011 |
20110215931 | METHODS AND APPARATUS FOR ASSESSING HEAD TRAUMA BASED ON CONFORMAL SENSING OF FORCE AND/OR CHANGE IN MOTION OF A PERSON'S HEAD - Sensing a force and/or a change of motion proximate to a person's head via one or more sensing elements (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the person's head. The conformality of the sensing element facilitates intimate proximity to the surface of the person's head to ensure accurate sensing. A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma. A conformal sensing apparatus may be integrated with a protective garment or accessory, such as a helmet, wherein the conformality of the sensing apparatus also ensures sufficient comfort for the wearer. | 09-08-2011 |
20110218756 | METHODS AND APPARATUS FOR CONFORMAL SENSING OF FORCE AND/OR ACCELERATION AT A PERSON'S HEAD - Sensing a force and/or a change in motion proximate to an arbitrarily-shaped surface via a conformal sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate and having a sufficient mechanical coupling to the surface. The conformality of the sensing element facilitates intimate proximity to the surface to ensure accurate sensing. Examples of arbitrarily-shaped surfaces include body parts of a person (e.g., a head). A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma.

20110218757 | METHODS AND APPARATUS HAVING POWER CONTROL FEATURES FOR CONFORMAL SENSING OF CHANGE IN MOTION OF A BODY PART - Sensing a change in motion proximate to a body part of a person via one or more sensing elements disposed on a flexible substrate and having a sufficient mechanical coupling to the body part. A proximity of the sensing element(s) to the body part is detected, and power is coupled to or decoupled from the sensing element(s) based at least in part on the detected proximity. | 09-08-2011 |
20120092178 | METHODS AND APPARATUS FOR CONFORMAL SENSING OF CHANGE IN MOTION AT AN ARBITRARILY-SHAPED SURFACE - Sensing a change in motion proximate to an arbitrarily-shaped surface via a single sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the arbitrarily-shaped surface. The change in motion may include at least one of an acceleration, an orientation, a vibration shock and a falling process. In one example, the flexible substrate substantially conforms to the arbitrarily-shaped surface so as to facilitate intimate proximity to the arbitrarily-shaped surface. In another example, a coupling mechanism may mechanically couple the sensing element to the arbitrarily-shaped surface. One or more LEDs coupled to the sensing element may provide a visual cue representing impact or trauma to the surface based on different colors respectively corresponding to a degree of the impact or trauma. | 04-19-2012 |

20130245388 | ELECTRONICS FOR DETECTION OF A CONDITION OF TISSUE - Apparatus are provided for monitoring a condition of a tissue based on a measurement of an electrical property of the tissue. In an example, the electrical property of the tissue is performed using an apparatus disposed above the tissue, where the apparatus includes at least two conductive structures, each having a non-linear configuration, where the at least two conductive structures are disposed substantially parallel to each other. In another example, the electrical property of the tissue is performed using an apparatus disposed above the tissue, where the apparatus includes at least one inductor structure. | 09-19-2013 |
