  • Publication number: 20180082876
    Abstract: A method for transporting a cassette pod for containing semiconductor waters is provided. The method includes transporting a cassette pod configured to receive a semiconductor wafer with a transporting apparatus. The method further includes supplying a gas from a cylinder into a housing of the cassette pod. The cylinder is externally positioned on the housing. The method also includes detecting a gas pressure in the cylinder with a detection element. In addition, the method includes issuing a signal to the transporting apparatus when the gas pressure in the cylinder is lower than a predetermined limit.

  • Patent number: 9837293
    Abstract: Embodiments of mechanisms for charging a gas into a cassette pod are provided. A method for charging a gas into a cassette pod includes loading at least one semiconductor wafer into a housing of the cassette pod after the at least one semiconductor wafer is processed by a processing apparatus. The method also includes removing the cassette pod from the processing apparatus by a transporting apparatus to a predetermined destination. The method further includes charging a gas into an enclosure in the housing of the cassette pod from a gas supply assembly disposed on the housing.

  • Publication number: 20170265146
    Abstract: A control method for a radio frequency (RF) receiver of a user equipment (UE) and UE are provided. The control method includes the steps of detecting whether at least one blocker exists; determining a current scenario of the UE when the blocker does not exist; obtaining a signal-to-noise-ratio (SNR) target corresponding to the current scenario; and selecting an operation mode from a plurality of power modes according to the SNR target to operate the RF receiver.

  • Patent number: 9026883
    Abstract: A decoding apparatus has an on-chip buffer, an external buffer interface, and a turbo decoder. The on-chip buffer is arranged for buffering each code block to be decoded. The external buffer interface is arranged for accessing an off-chip buffer. The turbo decoder is arranged for decoding a specific code block read from the on-chip buffer. The specific code block is not transmitted from the on-chip buffer to the off-chip buffer via the external buffer interface unless decoding fail of the specific code block is identified.

  • Publication number: 20100177110
    Abstract: A method of fast coloring a polygon for calculating areas of figures, the method comprising steps of resetting record values of all coordinate points to zero in the memory space; inputting the coordinate value of the ordered nodes defining the polygon into the memory space; connecting the nodes according to a predetermined order to determine connection points between the nodes; assigning a record value of each of the nodes as a flag value or a line value; assigning a record value of each of the connection points as a flag value or a line value; and calculating the area of the polygon by processing record values of the coordinate points in the memory space according to the record values of the nodes and the record values of the connection points. The method of fast coloring a polygon of the present invention is implemented with ordinary instead of complicated hardware configurations.
