patente de invenção: sistema e método de proteção ativa/standby para serviços de multicast do lado do usuário e dispositivo de roteamento. a presente invenção refere-se a um dispositivo de roteamento. o dispositivo de roteamento e pelo menos um segundo dispositivo de roteamento são ambos conectados a um dispositivo de convergência. o dispositivo de roteamento é um dispositivo ativo e inclui um módulo de backup de sincronização de informação de usuário configurado para sincronizar a informação de usuário de serviço multicast em pelo menos um segundo dispositivo de roteamento em tempo real através do dispositivo de convergência. a presente invenção também refere-se a um sistema e a um método de proteção ativa/standby para serviços multicast do lado do usuário. na presente invenção, um dispositivo de roteamento ativo e um dispositivo de roteamento standby serviços são configuradas no lado do usuário, e a informação de usuário é sincronizada no dispositivo de roteamento standby em tempo real. por isso, com a comutação ativa/standby, a identificação e a autenticação de usuário não são afetadas, por meio do que a validade do canal e do tráfego de usuário é assegurada. adicionalmente, benefícios econômicos de um operador são garantidos. além disso, com a presente invenção, a velocidade de comutação é acelerada, a continuidade do serviço é assegurada, e a qualidade de experiência de um usuário é aperfeiçoada. patent: active protection / standby system and method for user-side multicast services and routing device. The present invention relates to a routing device. the routing device and at least a second routing device are both connected to a convergence device. The routing device is an active device and includes a user information synchronization backup module configured to synchronize multicast service user information on at least one second real-time routing device through the convergence device. The present invention also relates to a system and active protection / ...

Pulse width modulation circuit

A pulse width modulation (PWM) system includes a PWM circuit and a controller. The PWM circuit includes a counter, a period register, and a duty cycle register. The controller is coupled to the PWM circuit. The controller is configured to calculate a period value and a duty cycle value. The controller is also configured to load the duty cycle value into the duty cycle register responsive to a count value of the counter being equal to a value of the duty cycle register and the duty cycle value being less than the period value.
