  • Publication number: 20170295324
    Abstract: A camera system is configured to capture 360 degree image information of a local area, at least a portion of which is in stereo. The camera system includes a plurality of peripheral cameras, a plurality of axis cameras, a first rigid plate, and a second rigid plate, each aligned along an alignment axis. The peripheral cameras are arranged in a ring configuration that allows objects in the local area past a threshold distance to be within the fields of view of at least two peripheral cameras. The first and second rigid plates secure to a top and a bottom surface of the ring of peripheral cameras, respectively. At least one axis camera is arranged along the alignment axis and is coupled perpendicularly to a surface of the first rigid plate.

  • Patent number: 9645014
    Abstract: A sensor surrogate (120) for causing a heating, ventilating, and air conditioning (HVAC) system (110) to maintain a desired room temperature, contains a temperature sensor (122) for determining an actual room temperature and logic embodied on at least one non-transitory computer readable medium (130). The logic (130) is configured to perform the steps of: calculating a current low temperature that is lower than a pre-programmed HVAC system temperature and providing the HVAC system with a first signal that represents the calculated current low temperature, if the desired temperature is above the pre-programmed HVAC system temperature; and calculating a current high temperature that is above the pre-programmed HVAC system temperature and providing the HVAC system (110) with a second signal that represents the calculated current high temperature, if the desired room temperature is below the pre-programmed HVAC system temperature.

  • Patent number: 9476428
    Abstract: A turbine-driven alternator (i.e., a turbomachine) suitable for generating electrical power from process gas waste energy. In particular suitable for very high density process gases such as super critical CO2, R134a, R245fa, etc. The turboalternator comprises two separate machines, specifically, a turbine device and an alternator device operatively connected together by a coupling shaft. The rotating shaft assemblies for each machines on the turbine side and the alternator side are supported by hydrodynamic foil gas bearings. The foil gas bearings use process gas at the turbine side, enabling high-pressure operation (˜3000 psia) and thrust load balancing. At the alternator side, cooling fluid is used in the foil gas bearings, enabling high-speed (˜40,000 rpm), low-windage, oil-free operation with closed-loop shaft cooling.

  • Publication number: 20160131398
    Abstract: Burner holders and cartridges of a furnace are described herein, which include a support assembly and a manifold. The support assembly is configured to support one or more burners. For example, the support assembly may include a burner holder with a cutout region, which may allow a burner to be moved between an operational position and a disengaging position by twisting the burner. The cutout region can allow the one or more burners to be removed or installed relatively easily, without the need of removing the manifold from the support assembly. The manifold can be attached to the support assembly by, for example, using one or more orifices as fasteners.

  • Patent number: 9040563
    Abstract: Many GTPases such as Ras, Ral and Rho require post-translational farnestylation or geranylgeranylation for mediating malignant transformation. Dual farnesyltransferase (FT) (FTI) and geranylgeranyltransferase-I (GGT-1) inhibitors (GGTI) were developed as anticancer agents from based on an ethylenediamine scaffold. On the basis of a 4-fold substituted ethylenediamine scaffold, the inhibitors are structurally simple and readily derivatized, facilitating extensive structure-activity relationship studies. The most potent inhibitor is compound exhibited an in vitro hFTase IC50 value of 25 nM and a whole cell H-Ras processing IC50 value of 90 nM. Several of the inhibitors proved highly selective for hFTase over the related prenyltransferase enzyme geranylgeranyltransferase-I (GGTase-I).

  • Publication number: 20150120766
    Abstract: The method involves aggregating post text, information about the type of content that has been posted, the post's creation time (time stamp), geographical origin (geo tag) and the username and storing it in a database. In order to search content that has been stored a web-server prompts clients for their search terms which it then parses. The webserver is programmed to identify portions of the search terms as corresponding to locations, hashtags or general search keywords. The method then involves interrogating the database to return relevant results from the vast array of social media content. The results are initially presented back to clients as links comprising markers on a map described on the screen of the client's device. The client can scroll the map view in order to also see the results in a list format. The client can then refine the results according to a number of filters.

  • Publication number: 20140344722
    Abstract: The present invention relates to a system and method for interacting with a social network. The method includes displaying a web page provided by a content provider on a user device. The web page includes at least one social network access item. The social network access item may be selected by a user of the user device, with a first type of selection causing a link to an online resource associated with a social network provider to be followed by the web browser, the online resource enabling the user to login to a social network. Receiving a second type of selection causes at least one control option to be displayed within the web page. The control option may be for saving details of the web page to a storage location remote from the user device and provided by the social network provider, or accessing the details of at least one web page previously saved by the user from the storage location.
