  • Patent number: 8973421
    Abstract: A competence diagnosis system for a urea water temperature sensor that can prevent a misdiagnosis when urea water is replenished in a urea tank. The system includes a urea water level condition determination unit that stores a urea water level, which is measured by a level sensor provided in the urea tank, in a storage unit immediately before key-off, obtains a level difference between the urea water level stored in the storage unit and a current urea water level after key-on, and allows a diagnosis by the competence diagnosis unit through temperature comparison when the level difference is less than or equal to a predetermined threshold value.

  • Publication number: 20150052967
    Abstract: A test sample is provided for testing performance of measuring and monitoring equipment for production lines, for example for foodstuffs or pharmaceuticals, and in particular, contamination monitoring equipment employing X-rays and/or metal detectors to spot foreign bodies in packaged products. The test sample may comprise a laminated card enclosing a standardised test piece such as a metal particle of specified size. The card or other sample may bear at least one identification containing a barcode, readable by an optical scanner. To test the equipment, a card is placed on a product package passing through the equipment, the optical scanner reads the barcode to confirm that the correct test sample has been submitted, and the results for the test sample are recorded in a computer log. If the results do not match those expected from the particular test sample submitted, the equipment fails the test and requires recalibration or repair.

  • Patent number: 8954184
    Abstract: System(s) and method(s) are provided for adjustment and analysis of performance of a tool through integration of tool operational data and spectroscopic data related to the tool. Such integration results in consolidated data that enable, in part, learning at least one relationship amongst selected portions of the consolidated data. Learning is performed autonomously without human intervention. Adjustment of performance of the tool relies at least in part on a learned relationship and includes generation of process recipe parameter(s) that can adjust a manufacturing process in order to produce a satisfactory tool performance in response to implementation of the manufacturing process. A process recipe parameter can be generated by solving an inverse problem based on the learned relationship.

  • Patent number: 8952803
    Abstract: A regional security system includes a control panel which can receive one or more delay parameters, associated with a type of sensor or detector, or a portion of a region being monitored. The delay parameters can be stored in a programmable storage unit. When an alarm indicator has been received from one of the sensors or detectors, an alarm indicating message along with an associated, programmed and pre-stored delay can be forwarded to a central station. If the system is disarmed before the delay interval has terminated, a cancel message can be sent to the central station.

    Abstract: Disclosed herein is an apparatus for inspecting a physical quality sensor, the apparatus including: a measuring unit measuring at least one reference sensor and an inspected sensor; and a display unit electrically communicated with the measuring unit. The measuring unit includes: a base including a first seating part mounting a reference substrate having at least one reference sensor mounted thereon and a second seating part seating the inspected sensor to be adjacent to the reference sensor; and an upper cover including a through-hole exposing the reference sensor and the inspected sensor to surrounding atmosphere and formed in a plate shape covering at least one reference sensor and the inspected sensor. According to the present invention, measured data of the inspected sensor is compared to measured data of the reference sensor under the same condition, such that it is determined that the inspected sensor is a good product.

  • Patent number: 8949060
    Abstract: In order to set an inspection area in an inspection apparatus for inspecting a board, a plurality of measurement areas are set on a board, and then reference data and measurement data of at least one adjacent measurement area that is adjacent to a target measurement area for inspecting a measurement target, among the measurement areas, are acquired. Thereafter, at least one feature object is extracted from the adjacent measurement area. Then, a distortion degree is acquired by comparing reference data and measurement data corresponding to the feature object with each other, and thereafter the distortion degree is compensated for, to set an inspection area in the target measurement area. Thus, a conversion relation between the reference data and the measurement data may be correctly acquired, and an inspection area, in which distortion is compensated for, may be correctly set.

  • Patent number: 8935128
    Abstract: The interference-compensated sensor for detecting an object located in a detection area in a contactless manner, particularly a rain sensor, is provided with a first and a second measuring channel each having a control device and an output, wherein both measuring channels are substantially identical. The sensor further comprises a main subtractor having an output for outputting the difference of the signals at the outputs of the measuring channels. The sensor is provided with a controller unit having an input that is connected to the output of the main subtractor and with an output for outputting a controller signal, by means of which the two measuring channels can be controlled in such a way that the signal at the output of the main subtractor can be controlled to zero. By means of the magnitude of the signal at the output of the controller, it can be determined if an object is located in the detection area.

  • Patent number: 8918226
    Abstract: A temperature measuring method accurately measures a sheet-like object even when the sheet-like object has an uneven temperature distribution throughout. In this method, temperature measurement is conducted in a measuring area where the sheet-like object is to be measured for its physical quantity or in the vicinity of the measuring area during determination of the physical quantity by a physical quantity measuring device. One or more temperature sensors are located at a position proximal to each sheet-like object that streams in a predetermined direction relative to the temperature sensors, and air is jetted out toward the sheet-like object for creating an air curtain that surrounds each temperature sensor so that a gauge workspace substantially confining the atmosphere therein is defined over one or both of the opposite surfaces of the sheet-like object. The temperature sensors detect the temperature in the measuring area or its vicinity within the gauge workspace.
