Title: Capacitive touch screen
Inventor: MA ZHENG
IPC: H05K1/11
Filed: 2018-11-02
Abstract: The present utility model provides a capacitive touch screen, comprising a flexible circuit board and a conducting medium filled above and below the flexible circuit board, wherein the flexible circuit board comprises a base material, and a first copper foil which is in contact with the conducting medium covers an upper surface of the base material. Based on the structure, and in conjunction with the feature that an internal stress generated by a lower surface of the flexible circuit board is greater than that of an upper surface thereof, under the influence of an external force and an environmental stress or when low temperature shrinkage occurs in the conducting medium, the first copper foil and the conducting medium cannot be separated, and the separation of a lower surface of the base material and the conducting medium cannot cause the disconnection of a circuit of the capacitive touch screen, with no influence on the normal use of the capacitive touch screen. Therefore, such a structure of a flexible circuit board improves the stability of a capacitive touch screen. Compared with the prior art, the capacitive touch screen cannot be easily damaged, and has a long service life.

Abstract: Various examples with respect to synchronization signal block (SSB) raster shift in mobile communications are described. A processor of a user equipment (UE) performs an initial cell search to identify a cell among one or more cells of a wireless communication system. The processor then camps on the identified cell. In performing the initial cell search, the processor scans through a plurality of SSB entries for frequency bands below 3GHz with a SSB raster spacing and a SSB raster offset frequency that support sub-carrier spacing (SCS) spaced channel raster and 100kHz channel raster for both 15kHz SCS and 30kHz SCS. A minimum channel bandwidth at 5MHz or higher for 15kHz SCS or at 10MHz or higher for 30kHz SCS is supported. The SSB raster spacing is a common multiple of 15kHz and 100kHz. The SSB raster offset frequency for 100kHz channel raster is a multiple of 30kHz plus/minus 10kHz.
