  • Publication number: 20240111612
    Abstract: Provided herein are systems and methods for multi-event correlation. Receiving a stream of events, each leaf rule engine may detect a plurality of events from the stream that matches a characteristic for the leaf rule engine. Each leaf rule engine may identify, from the plurality of events and within a time window, a group of events that satisfies a condition for the respective leaf rule engine. A root conditions engine may receive a stream of leaf events corresponding to the group of events identified by each leaf rule engine. The root conditions engine may identify, from the received stream of leaf events and within a root time window, a collection of events that satisfies a condition for the root conditions engine. A trigger may execute an action according to the collection of events identified within the root time window.

  • Patent number: 10837828
    Abstract: A non-attenuating meter determines optical energy of laser light in an absence of optical attenuation of the laser light and includes: a recipient mirror that: receives laser light that propagates in a primary propagation direction; produces profile light; transmits the profile light through the recipient mirror along the primary propagation direction; produces first reflected light from the laser light; and reflects the first reflected light along a secondary propagation direction; a profilometer in optical communication with the recipient mirror and that: receives the profile light from the recipient mirror along the primary propagation direction; and produces a profile signal from the profile light; a sensor mirror in optical communication with the recipient mirror and a passer mirror and that: receives the first reflected light from the recipient mirror along the secondary propagation direction; produces, in a tertiary direction, a sensor force from the first reflected light; communicates the sensor force

  • Patent number: 9291499
    Abstract: A radiometer includes a substrate; a radiation absorber disposed on the substrate to absorb radiation; a thermal member disposed on the substrate to change electrical resistance in response to a change in temperature of the radiometer; and a thermal link to connect the radiometer to a thermal reference, wherein the radiation absorber, the thermal member, or a combination comprising at least one of the foregoing includes a plurality of carbon nanotubes, the carbon nanotubes being mutually aligned with respect to the substrate, and the radiometer being configured to detect optical power.
