  • Patent number: 11996962
    Abstract: A communication system is configured to use a pulse width modulation signal as transmission code among a plurality of nodes connected to a communication line. A master node includes a transmission transistor connected to the communication line, a detector configured to detect a variation in current during the on-period of the transmission transistor, and a communication circuit configured to determine the off-timing of the transmission transistor based on the timing of occurrence of the variation in current (i.e., the on-timing of a second transmission transistor provided in a slave node). For example, the communication circuit can be configured to determine the off-timing of the transmission transistor such that the simultaneously-on period TB of the transmission transistor and the second transmission transistor fulfills TB=(2n?1)/2f, where f is the frequency of EMI noise.

  • Patent number: 11971288
    Abstract: A level meter includes light emission segments forming an emission region, a register portion to register a default emission condition and an emission-condition specified value, and a control portion. The control portion controls the light emission so that the emission region spreads in an emission proceeding direction according to an increase in numerical quantity to be expressed. An emission-condition specified value indicates a command to apply a predetermined specified emission condition concerning a subsequent segment positioned on a more upstream side than a foremost segment positioned on a most downstream side in the emission proceeding direction. The control portion allows all the light emission segments forming the emission region to emit light based on the default emission condition, and the control portion allows the foremost segment to emit light based on the default emission condition whereas allowing the subsequent segment to emit light based on the specified emission condition.
