Abstract:
A touch sensing system including a touch interface and a control unit is provided. The touch interface senses at least one edge change of at least one region on the touch interface corresponding to at least one object. The control unit defines a touch gesture corresponding to the object according to the edge change so as to perform a touch operation corresponding to the touch gesture. Additionally, a touch sensing method is also provided. In the touch sensing method, whether the touch gesture is a moving gesture, a rotation gesture, a flip gesture, a zoom-in gesture, or a zoom-out gesture is determined according to any change of a touch region.

Abstract:
A battery casing includes a plastic frame having a top receiving section and a bottom receiving section, a metal first plate and a metal second plate respectively assembled on the top receiving section and the bottom receiving section. A plurality of first assembling grooves is defined in a rim of the top receiving section, and a plurality of second assembling grooves is defined in a rim of the bottom receiving section. A plurality of first assembling arms extends from a rim of the first plate for being embedded in the first assembling grooves by ultrasonic. A plurality of second assembling arms extends from a rim of the second plate for being embedded in the second assembling grooves by ultrasonic. The first assembling arms offset with respect to the second assembling arms. Therefore the battery casing has decreased height to meet tendency of small profile and facilitates repairing simultaneously.
