摘要： A communication means (105) of a battery monitoring device (101) receives setting information (measuring parameters) about the type or structure of a storage battery (102) to be monitored from a host system (106). A setting means (107) acquires the measuring parameters and performs setting for a measuring means (103) and a digital signal conversion means (104). In other words, the setting means (107) sets, in accordance with the type or structure of the storage battery (102), the measuring parameters (namely, the measuring time interval, the measuring channel number, the measurement range and the like) for the measuring means (103) and the digital signal conversion means (104). Thus, even when the type and construction of the storage battery (102) changes, state of charge and the like of the storage battery (102) can be accurately measured and monitored by the battery monitoring device (101).

摘要： Disclosed is a piezoelectric actuator drive unit that includes a piezoelectric actuator drive amplifier and a piezoelectric actuator drive unit power supply. Combinations of high and low signal levels of a first control signal, which controls the supply voltage and amplifier bias voltage of the piezoelectric actuator drive amplifier, and a second control signal, which controls the driving force of the piezoelectric actuator drive amplifier, are associated with a haptic feedback function, a receiver function for generating an audio output, and a speaker function for generating music or the like. Thus, the piezoelectric actuator drive unit, which vibrates a piezoelectric actuator, is adapted to the haptic feedback function, the receiver function, and the speaker function, and can optimize its power and drive amplifier characteristics.

摘要： An amplifier circuit is configured to be preceded by a single-ended-to-differential translate circuit using a BTL configuration operating at a low voltage and succeeded by amplifiers to amplify output signals VOT and VOB from the single-ended-to-differential translate circuit. The amplifier circuit activates a mute function of the subsequent amplifiers during state transition when the single-ended-to-differential translate circuit turns on. Consequently, the amplifier circuit fixes output signals OUTP and OUTN to 0 V and masks an output noise. The amplifier circuit inactivates the mute function after signals VOT and VOB become stable. Thereby, the amplifier circuit is capable of easily preventing a pop noise using a BTL configuration requested for high voltage output to drive a piezoelectric actuator.
