Abstract:
When a back cover of a mobile communication device with replaceable cover is replaced, the mobile communication device may perform a corresponding application or enable a special function according to the back cover. The mobile communication device includes a back cover and a body including a processing unit, a storage unit, and a second connection interface. The back cover includes an integrated circuit (IC) element and a first connection interface. The IC element has identification information. The storage unit stores at least an application and a mapping table. The mapping table records the corresponding application of each identification information. When the back cover is assembled to the body, the first connection interface is connected to the second connection interface. The processing unit receives the identification information and looks up the mapping table according the identification information. The processing unit enables the corresponding application according to the mapping table.
Abstract:
A switching method for an electronic device having sensing regions is mentioned. The switching method is configured to detect signals received by the electronic device, so as to switch the states of the electronic device. The switching method comprises receiving a first signal at a first moment and receiving a second signal at a second moment, wherein the first signal is generated by touching a first sensing region and the second signal is generated by touching a second sensing region; measuring a triggering duration and determining whether the triggering duration is consistent with a predetermined duration, when the first signal and the second signal are inputted simultaneously; switching the electronic device from a first state to a second state, if the triggering duration is consistent with the predetermined duration; and maintaining the electronic device in the first state, if the triggering duration is not consistent with the predetermined duration.
Abstract:
An image display device includes a display panel and a parallax optic. The display panel is provided with a stripe sub-pixel arrangement in which sub-pixels arranged in a first direction have identical colors, and sub-pixels arranged in a second direction have distinct colors. The pixel density in the first direction is twice the pixel density in the second direction of the stripe sub-pixel arrangement. The parallax optic has view-separation elements arranged in the first direction into multiple rows. Each view-separation element is positioned corresponding to two adjacent sub-pixels, and the view-separation elements in one row are staggered relative to the view-separation elements in immediately adjacent rows.
Abstract:
A foldable leg for furniture includes a tubular leg and a pivot assembly attached to a top of the tubular leg. The pivot assembly includes a front plate and two wing plates respectively perpendicularly extending from two opposite sides of the front plate and facing each other. Each of the wing plates has a curved top edge and an elongated slot longitudinally defined in each of the wing plates. A bracket is pivotally connected to the pivot assembly and includes two side plates parallel to each other, and each has a through hole defined in a lower portion of the side plate. A locking plate connects the two side plates and the locking plate is selectively locked by the pivot assembly. A spring has two ends respectively secured around the pivot pin and at a free end of the tongue of the pivot assembly.
