| 20080203307 | Encoded binary liveness detector - A device for detecting the presence of human skin including an illuminator source for providing a first encoded IR band and a second encoded IR band. The first encoded IR band is capable of being reflected from skin and the second encoded IR band is capable of being absorbed by skin. A detector receives the first and second encoded IR band after the bands have contacted the skin and provides an encoded signal indicating the presence or absence of each of the first and second IR bands. A processing unit decodes and processes the signal and indicates the presence of skin when the first IR band is present and the second IR band is absent. | 08-28-2008 |
| 20080219514 | Skin detection sensor - A device for detecting the presence of human skin including an illuminator source for providing an IR band at a predetermined frequency known as a blue LED. The IR band frequency ranges from about 400 nanometers (nm) to about 500 nm, and preferably from about 450 nm to about 485 nm. Most preferred is a blue LED with a frequency of about 468 nm. The band is reflected off a target and received by a sensor such as a photo detector. The value for human skin is compared to the signal detected. Other materials that have been used to spoof detectors have different values and thus are distinguished from human skin. | 09-11-2008 |
| 20090237203 | IDENTIFICATION WITH RFID ASSET LOCATOR FOR ENTRY AUTHORIZATION - A system for controlling access at secure facilities to locations and assets contained in those locations, comprising a biometric identification device, an RFID tag and receiver, and a database for processing information from them to allow or deny access to the locations and assets. The system ties into an existing network in the facility and also includes a programming device for evaluation of the biometric template and acknowledgement of the identification, if made. The system also controls the permissible locations of assets such as laptops, desktop computers, photographic equipment, weapons such as rifles, data storage devices and the like, such that while a person may have access to a location, use of an asset or removal of the asset may not be part of that person's authorized conduct. | 09-24-2009 |
| 20100013597 | Biometric medication container - A locked medication container can be unlocked opened in response to a person's matching biometric characteristic and satisfaction of pre-established rules of access relating to day and time. One type of characteristic is a finger or thumb print. A communication can be sent to a remote site indicating that access was attempted by a specific person at a specific date and time and was successful or unsuccessful. | 01-21-2010 |

| 20090105437 | HIGH REFRACTIVE INDEX PRESSURE-SENSITIVE ADHESIVES - The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted biphenyl group. | 04-23-2009 |
| 20090229732 | STRETCH RELEASABLE ADHESIVE - A stretch releasable adhesive article includes first and second opposed major surfaces and a pull tab, and at least a portion of at least one of the first and second major surfaces is adhesive. The adhesive article has a cross-sectional area—as measured normal to the axis defined by a stretch release force applied to the pull tab during the stretch release process—that has a defined width to thickness ratio, and the adhesive article may have a visible light transmission of at least about 90%, and a haze of no greater than 5%. | 09-17-2009 |
| 20100048804 | HIGH REFRACTIVE INDEX PRESSURE-SENSITIVE ADHESIVES - The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted biphenyl group. | 02-25-2010 |
| 20100222496 | HIGH REFRACTIVE INDEX ADHESIVES - The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.50. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted carbazole group. | 09-02-2010 |
| 20100316845 | DEBONDABLE ADHESIVE ARTICLE - An adhesive article is described that is debondable from substrates or adherends with the application of heat. | 12-16-2010 |
| 20110126968 | STRETCH RELEASABLE ADHESIVE TAPE - An adhesive tape that is stretch releasable, articles that contain the adhesive tape, and uses of the adhesive tape are disclosed. The adhesive tapes include a backing layer that is adjacent to at least one pressure-sensitive adhesive layer. The backing layer typically is optically clear and includes a poly(alkylene)copolymer. The pressure-sensitive adhesive layer is a silicone-based adhesive composition. In many embodiments, the adhesive tape is optically clear. | 06-02-2011 |
| 20110212325 | GENTLE TO SKIN ADHESIVE - Electron beam and gamma radiation crosslinked, silicone gel adhesives are described. Both nonfunctional and functional poly diorganosiloxanes are used. Methods of forming the adhesives, and medical articles incorporating such adhesives are also described. | 09-01-2011 |
| 20110237692 | TELECHELIC HYBRID AEROGELS - Methods of forming hybrid aerogels are described. The methods include forming a hybrid aerogel from a metal oxide precursor and a branched telechelic copolymer, e.g., co-hydrolyzing and co-condensing the metal oxide precursor and the branched telechelic copolymer. Aerogels and aerogel articles, including hydrophobic aerogels and hydrophobic aerogel articles are also described. | 09-29-2011 |
