20140187877 | ANALYTE PERMEABLE MEMBRANE SYSTEMS FOR OXIDATIVE AND OPTICAL STABILITY - A sensor that may be used to detect the presence, amount, and/or concentration of an analyte in a medium within an animal. The sensor may include a sensor housing, an indicator element embedded within and/or covering at least a portion of the sensor housing, and a membrane over the indicator element. The membrane may reduce indicator element deterioration by preventing immune cells, such as white blood cells, from contacting the indicator element, substantially prevent transmission of light of at least a specified wavelength or range of wavelengths through the membrane, and/or permit the analyte to pass through to the indicator element. The membrane may be an opaque diffusion membrane. The sensor may include a foil. The foil may block light and/or reduce indicator element deterioration. The membrane may reduce oxidation of the indicator element. | 07-03-2014 |

20140343381 | OPACITY CONSISTENT POLYMER GRAFT FOR OPTICAL SENSOR - A sensor (e.g., an optical sensor) that may be placed within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid) within the animal. The sensor may include a sensor housing and a polymer graft including indicator molecules and covering at least a portion of the sensor housing. The opacity of the polymer graft may remain substantially the same (i.e., may have little or no variation) over time. The sensor may include a photodetector, and variation in the opacity of the polymer graft does not cause a significant change in a measurement signal output by the photodetector. The polymer hydrogel may be made of polymers including acrylic acid and/or polyethylene glycol. | 11-20-2014 |
20150057509 | DRUG ELUTION FOR IN VIVO PROTECTION OF BIO-SENSING ANALYTES - A sensor (e.g., an optical sensor) that may be implanted within a living animal (e.g., a human) and may be used to measure an analyte (e.g., glucose or oxygen) in a medium (e.g., interstitial fluid, blood, or intraperitoneal fluid) within the animal. The sensor may include a sensor housing, an analyte indicator covering at least a portion of the sensor housing, and one or more therapeutic agents. The one or more therapeutic agents may reduce deterioration of the analyte indicator. The one or more therapeutic agents may be incorporated within the analyte indicator, a membrane covering at least a portion of the analyte indicator, and/or one or more drug eluting polymer matrices, which may be external to or within the sensor housing. | 02-26-2015 |
20150079669 | CRITICAL POINT DRYING OF HYDROGELS IN ANALYTE SENSORS - A hydrogel is dried by a critical point drying technique. The hydrogel may include indicator molecules embedded therein and may be part of a hydrogel-based device, such as, for example, an analyte sensor. | 03-19-2015 |

20140079264 | Ruggedizied Sound System - A sound system configured to play audio files in a variety of indoor and outdoor environments is disclosed. The system includes a housing, a speaker, a power supply, and a mounting attachment that provides protection for sensitive system components and allow the system to be securely attached to a variety of surfaces and objects. | 03-20-2014 |
20140079267 | Sound System for Portable Devices - A speaker assembly comprises a portable device receiver and leg, allowing users to enjoy hands free viewing or listening experience. The sound system can be configured to provide an enhanced listening experience via at least one of a virtual surround system, a speaker driver, one or more speakers, adjustable control functions, and retained or increased acoustic power. | 03-20-2014 |
20140079275 | Headphone Having Integrated Cord Storage - The present inventive subject matter provides a headphone with a cord support that permits storage of a cord. The headphone can be moved between a closed configuration and an open configuration through extension or eversion of a headphone element or elements. In the open configuration, a structure or a surface is exposed that provides a support for winding and storage of the cord. | 03-20-2014 |
20140131442 | Mobile Device Card Reader - A card reader for use with a mobile device includes a card reader body having an information reading area configured to receive a card, an information reader configured to read information stored on the card and a connection device disposed on the card reader body and configured to be removably connected to the mobile device. The card reader also includes a first arm extending in the first direction away from the card reader body and spaced apart from the connection device and an opposing second arm extending in the first direction away from the card reader body and spaced apart from the connection device. The first arm and the second arm are configured to contact the mobile device and limit movement of the card reader body with respect to the mobile device when the card reader body is connected to the mobile device via the connection device. | 05-15-2014 |
