Patent application numberDescriptionPublished
20140017960MULTI-PIECE SOCKET CONTACT ASSEMBLY - A system and method is provided for securing a spring body against a socket body, thereby reducing movement of the spring body during periods of vibration. Preferred embodiments of the present invention operate in accordance with a socket body that includes at least a proximal end, a spring body that includes at least a distal end, and a sleeve. In one embodiment of the present invention, the distal end of the spring body is configured to be placed over the proximal end of the socket body, and the sleeve is configured to be placed over the distal end of the spring body. The sleeve preferably includes an inner circumference that is sized to creating a frictional engagement between an inner surface of the sleeve and an outer surface of the spring body, and between an inner surface of the spring body and an outer surface of the socket body.01-16-2014
20140199879USER CONFIGURABLE CONNECTOR - A system and method is provided for assembling and/or customizing a connector. Preferred embodiments of the present invention operate in accordance with a connector that includes a plurality of removable contacts, and a connector body that can be customized to mate with a corresponding, and similarly configured connector. In one embodiment of the present invention, a contact is connected to a wire and inserted into an aperture in a retainer. The retainer is then inserted into a connector body, thereby resulting in an increase in friction between the retainer and the contact, and a backshell is attached to the connector body. At least one key is placed in at least one keyway on the connector body, resulting in a user-programmable connector. The connector is then mated with a corresponding connector that is similarly configured. The connectors are then secured using either a latch or lanyard mechanism.07-17-2014

20140030764METHODS AND DEVICES FOR ELECTROMAGNETIC AMPLIFICATION OF NUCLEIC ACIDS - Methods and devices for amplifying nucleic acids generally involve exposing the nucleic acid to an electromagnetic field, for example a mini-current magnetic field, while performing the steps of PCR. The PCR methods and devices provide numerous advantages over conventional PCR techniques and systems such as reduced reaction times, no heating requirements, and reduced amounts of reagents (e.g., optional use polymerases and primers). Additionally, the PCR methods and devices require significantly shorter reaction times (e.g., less than one hour) compared to conventional PCR techniques and systems (minimum 2 hours). Finally, as shown in the Examples, the PCR methods and devices amplify significantly more DNA compared to conventional PCR techniques and systems. Accordingly, the PCR methods and devices provide a more efficient and cost-effective way to perform PCR when compared to conventional PCR techniques and systems.01-30-2014
20140033360METHODS FOR INCREASING THE PRODUCTION OF PHENOLIC COMPOUNDS FROM THEOBROMA COCAO - Described herein are methods for enhancing the production of phenolic compounds from 01-30-2014
20140287425GLUCOSE AND INSULIN SENORS AND METHODS OF USE THEREOF - Described herein are glucose and insulin sensors. The sensors are composed of host cells with DNA specifically designed to produce fluorescence when the cells come into contact with glucose and/or insulin in the sample. Once the fluorescence has been quantified, it can be correlated with the amount of glucose and/or insulin present in the sample.09-25-2014
20140291551METHODS AND SYSTEMS FOR DETECTING AND QUANTIFYING PETROLEUM OIL BASED ON FLUORESCENCE - Described herein are systems and methods for detecting and determining the presence and grade of petroleum oil in a sample. The methods and systems use the fluorescence produced by one or more transition metals present in the oil to detect and determine the presence and grade of the oil in the sample. The fluorescence produced by the metals is also useful as marker for tracking presence oil in the soil. The methods and offset the problems of the existing exploration technologies described above mentioned. Additionally, the methods and systems can be useful in identifying other compounds related to petroleum oil, such as carbon, hydrogen, and other types of aromatic compounds.10-02-2014
20140353257COMPOSITIONS FOR WATER TREATMENT AND METHODS OF USING THEREOF - Described herein are compounds and compositions useful for removing contaminants from water, as well as methods for making and using the compounds and compositions. In one aspect, the compositions contain a source of gallium ions and a polysaccharide such as chitosan, which are inexpensive and safe for the environment.12-04-2014
