Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.

Abstract: A manufacturing method for a shielded gate trench device comprises the following steps: Step 1, forming a gate trench in a first epitaxial layer; Step 2, forming a first dielectric layer and fully filling the gate trench with a first polysilicon layer; Step 3, forming a top trench: Step 31, carrying out primary polysilicon dry-etching; Step 32, carrying out primary dielectric layer wet-etching to decrease the thickness of the first dielectric layer in the top trench; Step 33, carrying out secondary polysilicon dry-etching; Step 34, carrying out secondary dielectric layer wet-etching to remove the rest of the first dielectric layer on a side face of the top trench and to form the top trench; and Step 4, forming a trench gate in the top trench. By adoption of the manufacturing method, the gate-source capacitance and the gate-drain capacitance can be decreased, and thus, the input capacitance is decreased.

Abstract: Some embodiments provide a program that receives, from an application, a role-based permission (RBP) request specifying an RBP, a first user, and a second user. The RBP specifies a set of actions, a first set of users authorized to perform the set of actions, a second set of users on which the first set of users is authorized to perform the set of actions, and a relationship condition. When the relationship condition specifies a hierarchy-based relationship, the program determines valid users in the second set of users according to a hierarchy of users. When the relationship condition specifies a non-hierarchy-based relationship, the program determines valid users in the second set of users according to a relationship not based on the hierarchy of users. The program determines whether the first user is authorized to perform the set of actions on the second user based on the determined valid users.
