  • Publication number: 20160356653
    Abstract: There are many industrial applications in which non-contact temperature sensing is useful for increasing production speed and quality, such as printing, laminating, extrusion, and metal forming. Disclosed is a non-contact temperature determining apparatus which uses two wide wavelength bands integrating sensors to determine the radiance ratio of a target and thereby determine a corresponding temperature of the target. Also disclosed is a non-contact temperature determining apparatus in which a beam splitter passes one wide wavelength band to a sensor and reflects another distinct wide wavelength band to another sensor from which temperature can be determined. A disclosed embodiment of the dual waveband temperature detector improves upon traditional and currently available ratio pyrometers by further reducing the cost of the system, making installation and use easier, and improving temperature detection for low temperature industrial applications.

  • Publication number: 20160222637
    Abstract: A sanitary insert unit which is fittable on the water outlet of a sanitary outlet fitting and has a flow-restricting or control device with a flow-restricting or control element. The flow-restricting or control device or at least the flow-restricting or control element thereof is guided displaceably under pressure of inflowing water from a starting position counter to a restoring force into a flow-restricting or control position. A jet splitter is connected downstream on an outflow side of the flow-restricting or control device. The jet splitter divides the water flowing therethrough into a multiplicity of individual jets. A guide pin protrudes from the jet splitter on an inflow side. The flow-restricting or control element of the flow-restricting or control device is displaceably guided on the guide pin. The sliding path is limited between the jet splitter and a sliding stop on a pin end region of the guide pin facing away from the jet splitter.

  • Patent number: 9356920
    Abstract: A system differentiates good content from bad content in a user-provided content system. Messages are analyzed for features that characterize messages. A feature may occur in one or more messages. A feature that has more than a threshold number of occurrences in messages in a time interval is identified for further analysis. Enhanced authentication is requested from senders of the messages with occurrences of the identified feature. Based on the rate at which senders of the messages pass authentication, the content associated with the message is determined to be good content or bad content. Subsequent messages are blocked or successfully delivered based on whether features occurring in the messages are indicative of good content or bad content.

  • Patent number: 9130997
    Abstract: Behavior of an online system is modified dynamically using feature expressions and feature loops. A feature expression can be expressed as a combination of other features or feature expressions, thereby allowing specification of complex features. The sets of feature expressions and policies of an online system can be modified while the online system is running. Feature loops aggregate values of a feature expression across a plurality of actions, for example, number of occurrences of an event over a time interval. The online system evaluates a set of feature expressions in response to actions performed by users. Feature expressions are used to specify policies that determine how the online system reacts to certain types of user actions. The ability to dynamically modify the feature expressions and policies of the online system allows the online system to adapt to attacks by malicious users in a timely manner.

  • Patent number: 9114414
    Abstract: The invention relates to a flow regulator (1) having a flow regulator housing, with a rotor disk (9) being supported in a rotary fashion in the interior space of its housing, which is embodied at least in a partial section of the disk in a liquid-permeable fashion and (9) is in a driven connection with a rotor disk drive, which transfers the flow of the water flowing through the flow regulator housing into a rotary drive force used for a rotary motion of the rotor disk (9). Using the flow regulator according to the invention considerable water savings can be achieved without here any reduction of the volume flow being clearly discernible.

  • Publication number: 20150199444
    Abstract: Some embodiments include tracking events and classifying assets within a computer system. A time series of occurrences of an event type associated with at least one asset is generated. A first signal value and a second signal value is determined based on the time series. The at least one asset can be classified based on comparison of the first signal value and the second signal value. The time series can be based on at least one time window including time intervals. Counters to determine a number of occurrences of an event type can be associated with the time intervals. Each of the counters can be incremented upon occurrence of the event type associated with the at least one asset during an associated time interval.
