Abstract: A wireless communications device is provided with a first cache unit coupled to a memory unit, a wireless communications module, and a hybrid automatic repeat request (HARQ) combine component coupled to the first cache unit. The wireless communications module receives from a cellular network a wireless signal carrying first data corresponding to an HARQ process. The HARQ combine component reads second data corresponding to the HARQ process from the memory unit into the first cache unit, and combines the first data and the second data for an HARQ combining procedure.

Abstract: One of the embodiments of the invention provides an input-output calibration method performed by a processing unit connected to an output device and an input device. The output device and the input device correspond to an output device coordinate system and an input device coordinate system, respectively. The processing unit first derives M calibration points' coordinates in the input device coordinate system by using the input device to sense a viewer specifying the M calibration points' positions, wherein M is a positive integer. Then, the processing unit uses the M calibration points' coordinates in the output device coordinate system and coordinates in the input device coordinate system to derive the relationship between the output device coordinate system and the input device coordinate system.

Abstract: An exemplary method for determining a control output in a control domain includes: obtaining a control input of an input domain, wherein the control input includes a previous input value and a current input value; and dynamically adjusting a control resolution setting, and converting the control input of the input domain into the control output in the control domain according to the control resolution setting, wherein the control output includes a previous output value and a current output value corresponding to the previous input value and the current input value, respectively, the control resolution setting for the current input value is determined according to at least the previous input value, and the current output value is identical to the previous output value when the current input value and the previous input value are generated in response to a same user input.

Abstract: The invention provides a method for optical storage medium writing. First, raw data is transferred from a host to a primary memory. The primary memory is then read to obtain read-out data. A series of encoding steps are then carried out simultaneously to generate formatted data according to the read-out data. Finally, the formatted data is directly written to an optical storage medium without accessing the primary memory again.
