摘要:
A system and method that facilitates the configuration and control of components of a radio frequency identification (RFID) system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. The RFID system can be controlled by obtaining a representation of the physical space. Next, at least one region of interest is specified in the representation of the physical space. An interrogation zone is then specified in the representation of the physical space, in which the interrogation zone corresponds to the data reader. Next, at least one overlap region of the interrogation zone and the region of interest is specified. Information is then stored, including the representation, and the interest region, the interrogation zone, and/or the overlap region. Operation of the data reader is controlled as a function of the stored information.
摘要:
An architecture of an RFID system that facilitates the accessing of RFID tag data within an RFID environment. The architecture includes a plurality of RFID readers, each reader being operative to transmit a first RF signal for scanning at least one RFID tag disposed within an RF coverage region associated with the reader, and to receive at least one second RF signal including tag data in response to the scanning of the tag. The architecture further includes at least one host computer operative to execute at least one client application, and at least one controller/processor communicably coupled to the plurality of readers and the at least one host computer. The controller/processor is operative to control operation of the plurality of readers, to process the tag data received by the plurality of readers, and to provide the processed tag data to the at least one host computer for use by the at least one client application executing thereon.
摘要:
A system and method that facilitates the configuration and control of components of an RFID system, taking into account how the RFID system components are associated with one or more physical locations within an environment in which the RFID system is deployed. A user provides information specifying associations between the system components and the physical locations within the environment to obtain visual representations of configuration data generated therefrom with reference to a facility view, an RF coverage view, and a location view of the data. The facility view serves as a reference plane for placement and orientation of antennas associated with RFID readers, location benchmark tags, and the physical locations of interest. After each antenna is placed and oriented on the facility view, an estimate of the size and shape of the RF interrogation zone of each antenna is computed, and representations of the RF interrogation zones are provided on the facility view to obtain the RF coverage view of the data. Next, the user provides information specifying the physical locations of interest to obtain the location view of the data. A composite of the facility view, the coverage view, and the location view is then generated to obtain an enhanced visual understanding of how the system components and the physical locations exist within the system environment, and how the components and locations are associated with one another.

摘要:
The present invention is directed to two component coating compositions that cure under ambient conditions and more particularly to those having low VOC (volatile organic content) that are suitable for use in automotive refinish and Original Equipment Manufacturing (OEM) applications. The coating composition includes crosslinkable and crosslinking components, wherein the crosslinkable component includes a low polydispersity, low molecular weight copolymer having on an average 2 to 25 crosslinkable functional groups, such as hydroxyl, acetoacetoxy, carboxyl, epoxy, primary amine and secondary amine. The copolymer is polymerized from a monomer mixture that includes one or more non-functional methacrylate monomers and one or more functional acrylate monomers provided with the functional groups. The crosslinking component includes polyisocyanate, polyamine, epoxy, polyacid, ketimine, melamine, or a combination thereof. The invention is also directed to coating produced from the coating composition.
摘要:
A computer-implemented system for managing the underwriting, quoting and binding by an insurance company of an excess casualty insurance policy for an insured having a primary insurance policy with a primary insurance limit amount. The system selects and stores at least one standard industrial classification code ("SIC code") associated with the insured and a primary carrier name or multiple carriers associated with the primary insurance policy. A plurality of SIC code records corresponding to a plurality of SIC codes are stored in a database. Each of the SIC code records are linked to underwriting guidelines established and filed by the insurance carrier. These criteria include guidelines related to minimum premiums, hazard rating, underwriting authority, and referral criteria. Primary insurance carrier public bureau rating records are also stored in the database. Each of the primary insurance carrier public bureau rating records includes a field for storing a rating code representing a financial stability rating associated with a primary insurance carrier. The system displays for the insurance carrier underwriter a plurality of candidate risk modifiers associated with the retrieved SIC code record, and for documenting and storing a selected risk modifier code and related underwriting criteria associated with the policy. The system develops the quotation using a detailed description of the insured's operation, the minimum premium amount information, the selected hazard code, the selected risk modifier code, primary insurance limits, and one or more attachment points.
摘要:
A method of hydrolyzing peptide bonds in waste material from dissolved air flotation (DAF float) wastewater treatment systems is disclosed. The method according to the disclosure comprises controlling the pH of said DAF float; adding a lytic agent to said pH controlled DAF float; and incubating the lytic agent/DAF float mixture. The hydrolyzed peptide bonds allow for the cleaving of oil molecules from protein material thereby increasing oil extraction from wastewater streams.

The present invention is directed to a thermally initiated polymerization process. The process provides for heating in a reactor a reaction mixture comprising one or more acrylate monomers to a polymerization temperature ranging from 120° C. to 500°0 C., and polymerizing the reaction mixture into a polymer. Applicants made an unexpected discovery that acrylate monomers can be used as thermal initiators, which makes the process more economical than conventional thermally initiated polymerization processes. The reaction mixture can also include non-acrylate monomers. Several novel steps are also disclosed to control the molecular weight and the polydispersity of the resulting polymer are also disclosed. The polymers made by the low cost process of the present invention have wide application, such as in automotive OEM and refinish coating compositions.
