  • Modulation circuit and modulation method with digital ELD compensation
    Patent number: 9490835
    Abstract: A modulation circuit includes a digital quantizer and a compensation circuit. The digital quantizer is utilized to receive and truncate a digital quantizing input signal for generating a digital quantizing output signal. The compensation circuit compensates for a time delay of the modulation circuit and generates a compensation output signal. The digital quantizing input signal is generated by subtracting the compensation output signal from a digital integration output signal to compensate for the time delay before truncating the digital quantizing input signal.

  • Prioritized Generation of IDC Indication Message to Mitigate IDC Impact on UE Performance
    Publication number: 20160234852
    Abstract: A UE controls in-device coexistence (IDC) indication message generation to mitigate potential throughput impact on UE to maintain UE performance as much as possible. Under the proposed method, FDM-based solution is always preferred by the UE. Based on the IDC indication message generated by the UE, a network applies an IDC interference mitigation solution that prioritizes FDM-based solution. Specifically, the UE first sends an IDC message requesting FDM-based solution. In case the serving eNB does not respond, the UE sends a new IDC message by alternating IDC option. Even if a TDM-based solution has been received, the UE may continue requesting FDM-based solution to gain UE performance.

  • Thickening phase for spin coating process
    Patent number: 9360755
    Abstract: Among other things, one or more techniques and systems for performing a spin coating process associated with a wafer and for controlling thickness of a photoresist during the spin coating process are provided. In particular, a thickening phase is performed during the spin coating process in order to increase a thickness of the photoresist. For example, air temperature of down flow air, flow speed of the down flow air, and heat temperature of heat supplied towards the wafer are increased during the thickening phase. The increase in down flow air and heat increase a vaporization factor of the photoresist, which results in an increase in viscosity and thickness of the photoresist. In this way, the wafer can be rotated at relatively lower speeds, while still attaining a desired thickness. Lowering rotational speed of wafers allows for relatively larger wafers to be stably rotated.
