Abstract: An outlier IC detection method includes acquiring first measured data of a first IC set, training the first measured data for establishing a training model, acquiring second measured data of a second IC set, generating predicted data of the second IC set by using the training model according to the second measured data, generating a bivariate dataset distribution of the second IC set according to the predicted data and the second measured data, acquiring a predetermined Mahalanobis distance on the bivariate dataset distribution of the second IC set, and identifying at least one outlier IC from the second IC set when at least one position of the at least one outlier IC on the bivariate dataset distribution is outside a range of the predetermined Mahalanobis distance.

Abstract: A button module with vibration feedback and fingerprint sensing, a fingerprint sensing module for the same, and a control method for the same are provided. The fingerprint sensing module has a fingerprint sensing unit stacked on a vibration unit. When the fingerprint sensing module detects a fingerprint, the control unit or a host of an electronic device determines whether the fingerprint is authenticated. If it is not authenticated, the vibration unit is activated, so that the user realizes that the authentication is not passed in real time through the vibration. Then the user may quickly change another finger or move the finger's position to speed up the authentication process. This can prevent users from waiting to improve user experience.

Abstract: A touchpad and a sending unit for the same are provided. The sensing unit has two electrode layers and a separation assembly. The separation assembly has multiple deformation rooms and multiple gap assemblies. The deformation rooms communicate with the gap assemblies. The gap assemblies communicate with the exterior environment. When the upper electrode layer is pressed and deforms in the deformation rooms, the air in the deformation rooms is discharged through the gap assemblies so that the air does not accumulate in the remaining unstressed spaces to avoid resistance and to maintain the normal operation of the force sensing function.
