|| List of recent Mute-related patents
|Hardware control method and apparatus|
A hardware control method for multitasking drivers under a user mode is provided. The control method includes steps of: receiving a request for access to a hardware device from a current process under the user mode; determining whether the current process has obtained a mutual exclusion (mutex) of the hardware device; if affirmative, determining whether an identification of the current process and an identification of a previous process accessed the hardware device are the same; if negative, performing a context switch on the current process and the previous process accessed the hardware device to allow the current process to access the hardware device.
|Mute drive circuit|
A mute drive circuit includes a micro-controller including an i/o port; a mute circuit; and an npn transistor. When an electronic device using the mute circuit is plugged into an ac power source, the i/o port is set to the logic low, the mute circuit performs the mute mode.
|Earphone jack drive circuit|
An earphone jack drive circuit applied in an electronic device is provided. The earphone jack drive circuit includes a mute circuit; a micro-controller including a detect pin and a control pin; a delay switch circuit including a resistance, a capacitance, an npn transistor and a first current-limiting resistance.
|Managing shared computer resources|
Various systems, processes, and products may be used to manage shared computer resources. In particular implementations, managing shared computer resources may include the ability to execute a first process on a first central processing unit and execute a second process on a second central processing units, wherein the first process and the second process are operable to access a first resource, and to determine at a mutex controller which of the first process and the second process is allowed to access the first resource at a given time..
|System and method for supporting parallel threads in a multiprocessor environment|
A method and system for supporting parallel processing of threads includes receiving a read request for a container from one or more read threads. Next, parallel read access to the container for each read thread may be controlled with a manager module that is coupled to the container.
Methods, systems, and computer-readable media with executable instructions stored thereon for preventing deadlocks are provided. An inter-device mutex (idm) can be locked for a first client.
|Cpu/gpu synchronization mechanism|
A thread on one processor may be used to enable another processor to lock or release a mutex. For example, a central processing unit thread may be used by a graphics processing unit to secure a mutex for a shared memory..
|Providing automatic power control for a power amplifier|
A power control circuit is coupled to receive a feedback signal from a power amplifier (pa) and generate a control signal to control a variable gain amplifier (vga) coupled to an input to the pa based on the feedback signal. The power control circuit may include, in one embodiment, a mute circuit to generate a mute signal to be provided to the vga when the control signal is less than a first level and a clamp circuit to clamp a control voltage used to generate the control signal from exceeding a threshold level..
