Abstract: An electrode structure of rechargeable battery includes a battery tab stack, an electrode lead, a welding protective layer and a welding seam. The battery tab stack is formed by extension of a plurality of electrode sheets. The electrode lead is joined to one side of the battery tab stack. The welding protective layer is joined to another side of the battery tab stack opposite to the electrode lead. The welding seam extends from the welding protective layer to the electrode lead through the battery tab stack.

Abstract: A manufacturing method of a waveguide and a head mounted display device having the waveguide are provided. The head mounted display device includes a display unit, a first waveguide and a second waveguide. The display unit is configured to provide an image beam. The first waveguide is located between the display unit and the second waveguide. The first waveguide is configured to transmit the image beam to the second waveguide and adjust a light shape of the image beam to maintain a field angle and expand a pupil in a single dimension. The second waveguide is configured to transmit the image beam to outside of the head mounted display device, and the second waveguide can extend a light transmission path and provide a uniform image beam.

Abstract: An image capturing system and a lens module thereof are provided. The lens module includes a first barrel, a second barrel, a lens, a swing lever and a connecting shift. The first barrel has a bump. The second barrel is disposed inside the first barrel. The swing lever has a first end and a second end. The lens is disposed at the first end. The connecting shift connects the swing lever and the second barrel. The swing lever is rotated around the connecting shift. The bump is used for pushing the second end of the swing lever.

Abstract: A moving device is disclosed. The moving device includes a first lens barrel, a second lens barrel, a shutter module, a pushing lever, a flexible element, and a third lens barrel. The first lens barrel includes an upper edge and a groove which is at the upper edge. The second lens barrel is sleeved within the first lens barrel. The shutter module is disposed on the second lens barrel. The pushing lever includes a first end and a second end which is fixed within the groove of the first lens barrel. The flexible element is disposed besides the pushing lever for pushing the pushing lever. The third lens barrel is sleeved outside the first lens barrel. The third lens barrel includes a convex block.

Abstract: A digital picture frame includes a display unit connected movably to a base unit, and a driving unit operable so as to drive the display unit to move relative to the base unit between a lengthwise position and a widthwise position. A controller determines whether digital image data acquired from a memory unit is that of a portrait or a landscape, determines whether the display unit is currently at the lengthwise position or the widthwise position, controls the driving unit such that the display unit is moved to the lengthwise position when the digital image data is that of a portrait and to the widthwise position when the digital image data is that of a landscape, and subsequently controls the display unit to display the digital image data thereon. A method of displaying the image data on the display unit is also disclosed.

Abstract: A method for memory controlling is disclosed. It includes an embedded address generator and a controlling scheme of burst terminates burst, which could erase the latency caused by bus interface during the access of non-continuous addresses. Moreover, it includes a controlling scheme of anticipative row activating, which could reduce the latency across different rows of memory by data access. The method could improve the access efficiency and power consumption of memory.
