摘要:
A power transistor driving circuit for a single power source drives a predetermined load and prevents each of the drive circuit transistors from being damaged because they are not turned on simultaneously.

A system for controlling an automobile cooling fan utilizes a temperature-sensitive negative resistance device having a resistance which decreases as the temperature rises, and which increases as the temperature falls. Thus, if the cooling water temperature does not exceed a certain level, the cooling fan motor is not driven. If the temperature exceeds a certain level, the cooling fan motor is driven in proportion with the dynamic temperature variations. Therefore, a variable cooling fan speed is possible, and therefore, the cooling operation becomes efficient.

Provided are a system and method for a safe taxi service. The method for a safe taxi service in a mobile device includes: transmitting input information regarding a destination to a vehicle information system; periodically receiving information regarding a current location of a vehicle from the vehicle information system; comparing the current location with an expected path to the destination; and transmitting state information to an external system when it is determined, according to the comparing, that the current location deviates from the expected path to the destination to an extent equal to or greater than a predetermined limit.
摘要:
A controller for performing a zero voltage switching using a resonance mode converter, and an electronic ballast adopting the same, includes a power controller, a shutdown protection circuit and a brownout circuit, and performs a switching when voltage of a switching element is zero, thereby preventing excessive power consumption, enhancing efficiency and decreasing noise.

摘要:
A proportional solenoid valve control system limits the current flowing in a solenoid valve if the command current is higher than a fixed value which can be set by a user. A current command limiting circuit limits the current command by providing a fixed value as an output when a current command exceeds the predetermined level.
