摘要： In a brushless motor driving apparatus, a drive circuit arranged to rotate a magnet rotor by sequentially switching energization of coils of phases, detect a position of the magnet rotor based on back electromotive force voltage generated in each phase coil, and control the energization of each phase coil based on the detected position. The drive circuit is configured to energize each phase under duty control and, before the back electromotive force control, perform initial setting twice sequentially for sweeping energization duty with respect to each phase coil to set the magnet rotor in a predetermined initial position.

摘要： In a data communication system in which many nodes are connected to a common data bus so that each node can communicate with other nodes, a data frame to be transmitted from a node to other nodes includes a message having a variable length interposed between a signal indicating the length of the message and a signal indicating the end of the message in the frame. The message and the signals are coded according to a coding rule such as NRZ, and a bit stuffing rule is applied to the signal indicating the length of the message and the message while another rule violating the bit stuffing rule is applied to the signal indicating the end of the message. When the message length is changed due to noise or other causes in the course of data transmission, the signal indicating the end of the message is clearly detected at a receiving end because it is coded according to a rule different from the rule applied to the message and other signals. Further, since the length of the message actually received at the receiving end can be compared with the signal indicating the length of the message, transmission error can be detected without fail.
摘要翻译：在其中许多节点连接到公共数据总线使得每个节点可以与其他节点通信的数据通信系统中，要从节点传送到其他节点的数据帧包括插入在指示消息的长度和指示帧中消息结束的信号。消息和信号根据诸如NRZ的编码规则进行编码，并且将位填充规则应用于指示消息和消息的长度的信号，而将违反位填充规则的另一规则应用于指示消息结束。当消息长度由于数据传输过程中的噪声或其他原因而改变时，在接收端清楚地检测出指示消息结束的信号，因为它根据与应用于消息的规则不同的规则进行编码和其他信号。此外，由于可以将在接收端实际接收的消息的长度与指示消息的长度的信号进行比较，所以可以毫无疑问地检测到传输错误。

摘要： A synthetic wave is obtained which represents the synthesis of a transmitted wave radiated from a sensor and a reflected wave returned from a breathing human body, and the presence or absence of a human in the vehicle is detected from the envelope of the synthetic wave. When the presence of a human is detected continuously for a predetermined length of time, it is determined that a human is present in the vehicle.
