  • Publication number: 20150204782
    Abstract: A device and method for determining the assay result is disclosed. The device includes a photoelectric detection circuit and a processor, and an optical detection device which is set with a detection zone and a blank zone for measuring assay results, and the photoelectric detection circuit detects the light-reflection intensity signal, and feeds back the detected information to the processor, and the processor is preset with a threshold value changing with time, and determined value processed by the processor is compared with the preset threshold value to obtain the result of assay. The method for determining the assay result display the result when confirmed determined value is bigger than the preset threshold value or can not reach preset threshold value within a fixed time or detected signal can not be determined, wherein the threshold value changes with the time. The device and method for determining the assay result work more efficiently, measure more accurately and cost less than the prior art.

  • Publication number: 20130183199
    Abstract: An analyzing and reading device and an analyzing and reading method, for reading and analyzing a test strip for assay detection are disclosed. The test strip has a detection zone and a blank zone, the device includes a photoelectric detection circuit and a processor, wherein the photoelectric detection circuit includes at least two light sources which locate corresponding to the positions of the detection zone and the blank zone of the test strip and are able to emit lights corresponding to the detection zone and blank zone of the test strip, and at least one optical detectors which receive reflected lights from the above two zones; wherein lights emitted by the at least two light sources irradiate the detection zone and blank zone of the strip and are reflected therefrom, and then are received by the optical detector, which in turn feedback the detection information to the processor; the processor making analysis and decision based on the detection information received.

  • Patent number: 7647255
    Abstract: A method for conducting a repairable inventory analysis calculates the minimum number of repairable parts to be held in inventory while still being able to satisfy the demand for spare parts even in view of uncertain repair lead times. The method uses a set of equations that relates a customer service level to arbitrary probability distribution functions of a repair lead-time and a part arrival process. The distributions are then searched to locate the optimal inventory level in the distribution.

  • Publication number: 20080162235
    Abstract: The optimization algorithm described herein combines stochastic programming and intelligent enumeration schemes that exploit the problem structure to avoid evaluating solutions that on their face are known to be non-optimal. The optimization algorithm finds the module workscope decisions and LLP replacement decisions that minimize expected future maintenance cost per engine flight cycle. The optimization algorithm considers the enormous number of possible solutions, and determines the best one.
