Abstract

trata-se de métodos e aparelho para transmitir mensagens de correção de temporização de sensor com um controlador hospedeiro. os métodos e aparelho determinam as mensagens de sincronização que são transmitidas a um sensor acoplado ao controlador hospedeiro através de uma interface, onde as mensagens indicam um princípio de um período de sincronização para sincronizar a temporização do controlador hospedeiro e do sensor. adicionalmente, determina-se uma mensagem de tempo de retardo que indica um retardo de tempo entre o princípio do período de sincronização e um tempo de transmissão real da mensagem de sincronização. a mensagem de sincronização é transmitida com a mensagem de tempo de retardo em uma mensagem de informações ao sensor, onde a mensagem de informações é configurada para permitir que o sensor corrija a temporização de um temporizador de sensor considerando-se o tempo de retardo.These are methods and apparatus for transmitting sensor timing correction messages with a host controller. The methods and apparatus determine the synchronization messages that are transmitted to a sensor coupled to the host controller via an interface, where the messages indicate a beginning of a synchronization period to synchronize the timing of the host controller and the sensor. Additionally, a delay time message is determined indicating a time delay between the beginning of the synchronization period and an actual transmission time of the synchronization message. The synchronization message is transmitted with the delay time message in a sensor information message, where the information message is configured to allow the sensor to correct the timing of a sensor timer by considering the delay time.
