  • Patent number: 6649829
    Abstract: A connector apparatus for controlling fluid dispensing/transmission that includes a control component for communication between couplers thereof. A first coupler has a transmitter, and is releasably connected with a mating reader coupler that has a transmitter and fluid control device to exchange information with the transmitter of the first coupler. The transmitters communicate and are operated by wireless means such as by RF devices. Upon confirming that the first coupler is properly coupled to the mating coupler and that the first coupler has a proper identification, the fluid control device controls fluid flow, using the transmitters of the first coupler and the mating reader coupler, under predetermined parameters, e.g., pressure, temperature, duration, and flow rate, as indicated in the first coupler.

  • Publication number: 20030107648
    Abstract: A surveillance system includes video surveillance cameras that are in various locations sought to be monitored. Each camera is associated with a variable frame rate that is faster when motion is detected in the location and slower when little or no motion is detected, to improve resolution when needed. A system hub receives video feeds from the cameras and sends them on to wireless clients upon client request.

  • Publication number: 20020083008
    Abstract: A user of a verification system registers directly at the verification system web site or by proxy at the time of engaging in an e-transaction through a vendor's web site. Upon registration, the user provides personal information in a secure environment. The verification system checks the database to cross-reference the user-provided information with the government-certified, or non-government certified data stored in the verification system databases. The verification system then creates a unique identifier and a digital identification badge. The user inputs the unique identifier into the system at the start of an e-transaction and the digital identification badge is securely transmitted from the verification system to the vendor in response to the unique identifier. The vendor decrypts the digital identification badge to confirm that the user is authorized to make a particular e-transaction.

  • Patent number: 6247175
    Abstract: The present invention is a method and apparatus for identifying and removing unused software procedures from computer software loads at loadbuild time, and includes a compiler, linker, and other software loadbuild tools. The compiler has been adapted by the invention to define identify procedures that are unused by a software load by identifying all procedure calls, entry points, and required procedures in each module used by the software load and to incorporate this information into link records. Based on the information contained in the link records, a linker creates a temporal data structure referred to as a call graph that depicts the operational flow of the software load. The linker processes the call graph and determines those procedures that are called, and thus those procedures that are not called by a software load.

  • Patent number: 6206145
    Abstract: A brake apparatus engages and locks a piston of a hydraulic elevator drive carrying an elevator car or a cable pulley. Attached at the upper end of a hydraulic cylinder guiding the piston is a beam on which are pivotally mounted at least two brake arms at pivot points. The brake arms are pivoted by a slidable plunger toward and away from the piston. Each brake are carries a brake lining having a shoulder formed on an inwardly facing surface providing a transition from a piston contact portion to a recessed portion of the surface. The shoulder is positioned in the same generally horizontal plane as the brake arm pivot point for initially engaging the surface of the piston to reduce forces transmitted through the brake arms during engagement and disengagement.

  • Patent number: 6208858
    Abstract: A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal.

  • Patent number: 5824919
    Abstract: A flue gas probe that performs the sample conditioning functions of particulate and water removal at the point of sampling, i.e. within the flue or chimney. Particulate matter is removed by a porous ceramic filter positioned at one end of the probe. A polymeric drying element is also provided in order to remove water vapor from the sample by means of perevaporation.

  • Patent number: 5738773
    Abstract: A fuel cell sensor (10) comprises a main body (11) in which are mounted working electrodes (12), counter electrodes (13) and respective contacts (14 to 17). The working electrodes (12) are mounted facing each other to define a sample space between them. The electrodes (12) are electrically interconnected in parallel as are the two counter electrodes (13). This arrangement makes it possible to provide a very large working electrode surface area for a small volume sample space (22).
