  • Patent number: 10679054
    Abstract: Embodiments of the present invention provide a computer-implemented method for identifying a specified object. The method includes collecting attributes of a physical object within a physical space, in which the attributes include an object temperature obtained via an (IR) sensor and an object shape obtained via an image sensor. A machine learning algorithm is executed to allocate a coordinate to the object based on the attributes. In response to a request from a user to locate the object, the physical space is scanned via the IR sensor and the image sensor to identify the object and to detect a present location. An indication of a location of the object is then displayed to the user, in which the indication is at least one of the present location of the object or a predicted location of the object.

  • Patent number: 10656335
    Abstract: A method for cleaving a fiber comprises rotating an actuator to apply a positioning force to a blade in a scoring assembly. The positioning force produces a score in the surface of a fiber, and the method further comprise applying a cleaving force to the fiber to cleave the fiber. The method can further include measuring the magnitude of the positioning force and rotating the actuator until the magnitude corresponds to a pre-determined magnitude. A cleaver comprises a scoring assembly, drive assembly, and a cleaving assembly. The scoring assembly includes a holder having one or more blades, and an actuator. The cleaving assembly secures a fiber in the scoring assembly. The drive assembly rotates the actuator to position one or more blades to score the surface of the fiber. The cleaving assembly applies a cleaving force to the fiber to cleave the fiber at the location of the score.

  • Patent number: 10612978
    Abstract: Technical solutions are described for testing a light emitting diode (LED) device. An example method includes driving, by a controller, a filter unit to filter a light from the LED device using a first filter. The method further includes, in response to a sensor not receiving a measurable signal because of the first filter, driving, by the controller, the filter unit to filter the light using a second filter. Further, in response to the sensor not receiving the measureable signal because of the second filter, the method includes outputting an indication that the LED device is rejected. Further, in response to the sensor receiving the measureable signal, the method includes outputting an indication that the LED device is of a color representative of the second filter.
