  • Patent number: 10802068
    Abstract: A method of detecting abnormal test signal channel of automatic test equipment firstly obtains a raw test data and then divides into the data groups according to a mapping data. The test data of DUTs in one data group are generated by the same group of probes. A yield of each data group is further estimated. A yield of a wafer is further estimated when the yield of the data group matches a first failure threshold. An abnormal test signal channel is determined when the yield of the wafer does not match a second failure threshold or the yield of the wafer matches the normal threshold. Therefore, to add the detecting method in an original test procedure of the ATE, the operator easily identifies which blocks in the failure color on the test data map are caused by the abnormal test signal channel.

  • Patent number: 10649449
    Abstract: A technique is provided for providing early fault detection using process control data generated by control devices in a process plant. The technique determines a leading indicator of a condition within the process plant, such as a fault, abnormality, or decrease in performance. The leading indicator may be determined using principal component analysis. A process signal indicating a process variable corresponding to the leading indicator is then obtained and analyzed. A rolling fast Fourier transform (FFT) may be performed on the process signal to generate time-series data with which to monitor the process plant. When the presence of the leading indicator is detected in the time-series data, an alert or other prediction of the condition may be generated. Thus, process faults may be identified using fluctuations and abnormalities as leading predictors.

  • Patent number: 10630090
    Abstract: The present disclosure describes aspects of ripple current reduction for wireless electric vehicle charging. In some aspects, an apparatus for wireless power transmission includes an inverter circuit to provide alternating current and a resonant circuit having a tuning portion and a coil portion to transmit power based on the alternating current. The apparatus also includes a current sensor to provide an indication of peak-to-peak amplitude (e.g., ripple current) of the alternating current that flows to the coil portion of the resonant circuit. Based on this indication, a control signal of the inverter is altered to adjust the peak-to-peak amplitude of the alternating current, such as to reduce ripple current in the coil portion. By so doing, ripple current can be reduced in power-transmitting or power-receiving devices, which may improve power transmission efficiency, enable use of smaller decoupling capacitors, or reduce stress on elements of respective resonant circuits.

  • Patent number: 10410113
    Abstract: Systems, methods, and apparatus for time series data adaptation, including sensor fusion, are disclosed. For example, a system includes a variational inference machine, a sequential data forecast machine including a hidden state, and a machine learning model. The sequential data forecast machine exports a version of the hidden state. The variational inference machine receives as inputs time series data and the version of the hidden state, and outputs a time dependency infused latent distribution. The sequential data forecast machine obtains the version of the hidden state, receives as inputs the time series data and the time dependency infused latent distribution, and updates the hidden state based on the time series data, the time dependency infused latent distribution, and the version of the hidden state to generate a second version of the hidden state. The time dependency infused latent distribution is input into the machine learning model, which outputs a result.

  • Patent number: 10302325
    Abstract: The present disclosure is related to an air filter operation and use modification system. The system properly determines average filter resistance based upon determined air velocities in the air handling unit. Once accurate average filter resistance is determined, various energy use measurement determinations can be made for a proposed filter in the system. Such determinations can be based on estimated or desired filter energy use measurements. The system can modify the air handling unit operations to meet the proposed filter energy use measurements. Furthermore, the user will have the ability to review the range of potential operational points and then be able to select the service cycle based on the air handling unit owner's preferred preventive maintenance and budget cycles.

  • Patent number: 10295284
    Abstract: A computer-implemented method, environmental control system (ECS) for an aircraft, and system are provided. Air temperatures at the inlet and outlet of a ram air duct for an ECS are measured. Also, air temperatures at outlets from one or more heat exchangers arranged in the ram air duct are measured. The temperatures are typically measured when the aircraft is on the ground and when aircraft engines supplying air to the ECS are operating at idle. Shortly thereafter, the heat exchangers are manually inspected to determine a level of actual fouling (e.g., dirt, dust, or other debris accumulated on heat exchanger surfaces). A supervised machine learning or other statistical analysis is performed on the measured temperatures and associated actual fouling levels to develop a model that predicts an amount of heat exchanger fouling, based on the temperature measurements. An alert can be output if the predicted fouling exceeds a fouling threshold.
