  • Patent number: 8352051
    Abstract: An output module for an Industrial Process Control System that drives a load in a failsafe manner. The output module drives a load in response to a driving signal and includes a controller that generates a command signal and a drive enable signal in response to said driving signal. A keep alive circuit generates an active keep alive signal unless the drive enable signal is inactive. The output module includes a driver circuit that generates a drive signal in accordance with the command signal when the keep alive signal is active such that the load can be driven with a channel failsafe switch in response to the drive signal. The output module can be integrated into any of a number of industrial process control systems to enhance the operability of such systems.

  • Patent number: 8350405
    Abstract: A load control module is provided for use with a transfer switch apparatus that controls the delivery of standby electrical power to a load during utility power interruption. The load control module selectively brings loads online to receive standby electrical power to prevent overloading of the electric generator that is providing the standby electrical power. The frequency of the electrical power is also monitored and if a low frequency condition is detected, loads are taken offline (shed). A method to flag those loads that induce an overload condition is also provided.

  • Patent number: 8340117
    Abstract: TCP performance is improved over unreliable links so as to allow TCP connections to be set up when such connections are otherwise impossible. Out-of-band signaling may be used to synchronizing and establishing a connection between two TCP endpoints without modification to the TCP/IP protocol suite. A system may create a control channel to enable out-of-band signaling for TCP connection establishment between two TCP endpoints. The control channel may be achieved using a system that includes of a signaling broker, an agent application, and a virtual network interface and a capture module that together create the control channel for the TCP signaling traffic.

  • Patent number: 8334740
    Abstract: A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to be secured in generally close proximity to the stationary contact. During communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with the stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. A pair of arc guides extend along the magnetic intensifier and, cooperatively with the magnetic force, ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor. Such a construction increases the operable range and lifecycle of the contactor by reducing the damage associated with propagation of the circuit termination arc.

  • Patent number: 8330405
    Abstract: The present invention provides an improved current regulator for PWM based drives for electric motors. The invention provides compensation for the rotor position signal for delays introduced due to the PWM algorithm and for digital sampling present in such a drive. Current regulator commonly operate in a two-phase reference frame, requiring forward and reverse coordinate transformations between the physical current values and the two-phase reference frame variables. The present invention provides an improved compensation in the forward transformation by determining the phase lag between the commanded voltage reference and the output voltage reference and by further compensating the forward transformation for errors introduced due to sampling the current either at different sampling instances than the rotor position or at multiple sampling instances during a carrier period.

  • Patent number: 8322220
    Abstract: A method, and corresponding apparatus, of imaging sub-surface features at a plurality of locations on a sample includes coupling an ultrasonic wave into a sample at a first lateral position. The method then measures the amplitude and phase of ultrasonic energy near the sample with a tip of an atomic force microscope. Next, the method couples an ultrasonic wave into a sample at a second lateral position and the measuring step is repeated for the second lateral position. Overall, the present system and methods achieve high resolution sub-surface mapping of a wide range of samples, including silicon wafers. It is notable that when imaging wafers, backside contamination is minimized.

  • Patent number: 8316551
    Abstract: A bow sight automatically corrects and compensates for various dynamically changing aiming, shooting, and/or environmental conditions. The bow sight can perform situation-specific aim evaluations and corrections to correct or compensate for situation-specific shooting and environmental factors, at a given time and on a per-shot basis. The bow sight includes integrated sensor-type devices, such as a range finder, an inclinometer, and an anemometer, which detects values of situation-specific shooting and environmental factors and communicates such detected values with a processor or other control device. The processor uses the situational specific data, as well as bow and arrow performance data, and data from shot calibrations, to calculate precise vertical and horizontal aim compensations required to accurately hit the desired target point.

  • Patent number: 8321512
    Abstract: A method and software product for detecting unsolicited emails, e.g. spam, involves altering the case of at least some symbols comprising an email user's email address according to a predetermined criteria prior to transmitting an email message. The altered case sequence of the email user's address is stored in a database. Subsequently, as email's are received in the email user's mailbox their intended recipient addresses are processed to determine if they include symbols whose case sequence, i.e. uppercase and lowercase, matches one of the sequences that was previously stored. If no match is found then the incoming email is treated as potentially constituting spam and is handled as such. Embodiments of the invention take advantage of a property of most Internet post office email servers being that they are generally case insensitive in respect of the symbols that make up an email address.

  • Patent number: 8312873
    Abstract: A low depth telescoping downdraft ventilator controlled by an electronic controller providing a precisely controlled and efficient way of removing gases and fumes is disclosed. The low depth telescoping downdraft ventilator has the ability to fit behind a built-in oven placed below a cook top unit. The telescoping downdraft ventilator has an almost infinitely selectable range of heights above a cook top with a built in oven. The ventilator collects and draws in exhaust fumes and smoke, filters it and re-circulates or expels it either outdoors or indoors. The inner member of the telescoping ventilator may house the exhaust fans and may move up or down without the use of mechanical switches for elevation detection and stopping. The ventilator may have sensors to detect temperatures, filter change need, fan speeds, telescoping stop points, energy consumption, resistance and voltage, enabling programmable set point operation.
