Abstract: The present disclosure provides a computing apparatus and a method for securing access to the computing device. The computing apparatus comprises a housing, a data storage device disposed in the housing, a cover movably coupled to the housing to secure the data storage device in the housing, and a controller coupled to the data storage device. The controller is configured to grant access to the data storage device upon detecting an authorized attempt of opening the cover and to deny access to the data storage device upon detecting an unauthorized attempt of opening the cover.

Abstract: A digital dynamic trace adjustment pulse width modulate controller uses a core processing unit to receive a phase signal and outputs a pulse width modulate signal. It is observed that when the output voltage is rising or dropping then changing the pulse width modulate signal of the output end, the duty rate of the phase signal will be maintained at fifty percent degree.

Abstract: This invention relates to a digital time mirrored pulse width modulate controller. The controller is electrically connected to a converter unit in which it comprises at least one comparator unit. The comparator unit outputs/inputs a voltage (Vo) and a preset voltage (Vset), and outputs a phase signal having low-level and high-level standards and a core digital processing unit, wherein the core digital processing unit outputs a pulse width modulate signal, through the units mentioned above. The characteristics of the invention can be summed up as follows: the elapsed time of the phase signal in high-level and in low-level is equal, and the root mean square of the output voltage in converter unit is equal to the preset voltage (Vset).
