Abstract: The disclosure relates to enhancing performance at a device that implements a stand-alone global navigation satellite system (GNSS) receiver. In particular, a GNSS-enabled mobile device may obtain positioning data from one or more non-satellite sources and determine satellite signal quality in a surrounding environment. As such, in response to determining that the environment surrounding the GNSS-enabled mobile device is a weak satellite signal environment, the GNSS-enabled mobile device may trigger a process to provide the positioning data obtained from the one or more non-satellite sources to the device that implements the stand-alone GNSS receiver such that performance at the device that implements the stand-alone GNSS receiver may be enhanced in poor satellite signal environments.

Abstract: The present invention provides a PDP structure including a first substrate, a second substrate and a Waffle barrier rib structure located between the first and second substrate. The Waffle barrier rib structure includes three first barrier ribs having different width and a plurality of second barrier ribs perpendicular to the first barrier ribs. The second barrier ribs are located between the two first barrier ribs, and connect the wider structure of the two first barrier ribs. Therefore, discharge spaces are formed. Because of different width, the height difference of the barrier rib structure is formed after thermal process. Hence, gas can pass through the barrier ribs structure between the front and the back substrate sealed together.

Abstract: The invention discloses a plasma display panel (PDP). The PDP grounds an exposed transparent conductive layer to the inner component thereof, so as to shield off electromagnetic interference (EMI). Accordingly, there is no metal structure in the second protective layer formed on the transparent conductive layer, such that the second protective layer can be easily attached onto the transparent conductive layer. Therefore, the manufacturing of PDP is getting much easier, and the yield rate will then increase.
