Abstract: Aspects of this disclosure include technologies to detect unpackaged, unlabeled, or mislabeled products based on product images. Leveraging from improved machine learning techniques, the disclosed technical solution can reduce a full product space for product search to a partial product space. Accordingly, a limited number of product candidates in the partial product space may be visually presented for user evaluation. Sometimes, a product candidate is to be comparatively presented with a live image of the product via a uniquely designed graphic user interface, which further improves the confidence of the user and the accuracy of the underlying transaction.

Abstract: An actuator, especially for use in a game machine, includes a motor driving an output via a gear train. The motor is mounted to a support plate. The gear train includes a number of dual cogs rotatably mounted on fixed shafts. At least one of the fixed shafts is fixed to the support plate by way of a spacer. The support plate has a mounting hole formed in the support plate with an axially extending hollow boss and the spacer is fixed to the support plate by being press fitted into the mounting hole and boss. One of the fixed shafts is fixed to the support plate by a shaft seat which is fixed to the support plate by a snap-fit connection.
