  • Publication number: 20240077762
    Abstract: A display is disclosed. The display comprises a display panel, and an optical film disposed on a viewing side of the display panel. The optical film has a total haze ranging from 15% to 60%, an inner haze less than or equal to 10%, and a reflectivity satisfying the relationships of 0.35%?(RSCI-RSCE)?1.50% and RSCE?1.50%, wherein RSCI is an average reflectivity of diffuse component and specular component, and RSCE is an average reflectivity of diffuse component. By adjusting the total haze, inner haze and reflectivity of the optical film to satisfy the above relationship, the display can have good anti-glare properties, and the contrast ratio of the display will not be reduced too much to avoid the display quality be affected.

  • Publication number: 20230138504
    Abstract: An online signing system and method, a computing apparatus, and a computer-readable recording medium are provided. An assigned task is generated by a task assignment apparatus to the computing apparatus. The computing apparatus generates a signing request based on the assigned task to be transmitted to a client apparatus. The client apparatus downloads an assignment file from a storage database based on the signing request to display the assignment file on a display. The client apparatus receives an input via an input unit to generate a signature object on the assignment file, and transmits the signature object to the computing apparatus. After receiving the signature object, the computing apparatus combines the signature object and the assignment file to obtain a signed file, and transmits the signed file to the storage database.

  • Patent number: 9195296
    Abstract: Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.

  • Patent number: 8649306
    Abstract: The standby time of a CDMA cell phone is extended by using two receive chains to monitor the Quick Paging Channel (QPCH) when the signal-to-noise ratio falls within a predetermined range. Monitoring the QPCH saves battery power by obviating the need to monitor the general paging message unless quick paging (PI) bits are set. The QPCH is not monitored, however, in noisy environments where PI bits are incorrectly detected causing the paging message to be needlessly monitored. Power is saved by monitoring the QPCH in noisier environments without increasing the incorrect detection rate. Incorrect detection is reduced in the predetermined range by using an additional receive chain to achieve receive diversity. Although additional power is consumed by the second receive chain in the predetermined range, the power saved by not demodulating the paging message at each slot more than compensates for the additional power consumed by the second receive chain.
