  • Patent number: 9557852
    Abstract: A method of identifying a palm area for a touch panel has steps of: receiving sensing frame information having multiple touching sensing points from the touch panel; selecting one of the touching sensing points; outwardly extending a distance from an outline of the selected touching sensing point to define a searching range; checking whether other touching sensing points are within the searching range; marking the touching sensing points in the searching range and expanding the searching range based on the currently marked touching sensing points; sequentially selecting and checking each touching sensing point if it is within the present searching range; and finally merging all the outlines of the marked touching sensing points to form a final outline as a palm area. Other unmarked touching sensing points are defined as touching reference points.

  • Patent number: 9173313
    Abstract: A waterproof structure of a casing has a case body and a cover pivotally mounted on the case body. The case body has a recess, a water collecting sump defined in the recess and two abutting protrusions respectively formed on two opposite inner sidewalls of the case body. The cover has an outer shell, and an inner stop and two side stops formed on an inner surface of the outer shell. When the cover pivots to cover the recess of the case body, the inner stop and the side stops prevent moisture and dust from entering the case body from a clearance formed between a pivot edge of the outer shell and the water collecting side surface of the case body.
