  • Patent number: 11626724
    Abstract: A load control device includes a power supply terminal connected to a power source via a fuse, a load driver configured to drive loads by electric power supplied from the power source via the fuse and the power supply terminal, a current detector configured to detect load currents that flow through the loads, respectively, and a controller. The controller is configured to calculate a total current that flows through the fuse based on the load currents detected by the current detector, calculate a physical quantity correlating with the total current and related to a connecting member that connects between the fuse and the power supply terminal in response to that the total current is equal to or higher than a predetermined current value, and limit at least one of the load currents in response to that the physical quantity is equal to or greater than a reference value.

  • Patent number: 9873375
    Abstract: A vehicle approach alert device includes: a memory memorizing a warning sound source data for emitting a warning sound from an external sound emitting unit and a canceling sound source data for emitting a canceling sound from an internal sound emitting unit. The canceling sound cancels the warning sound transmitted from the external sound emitting unit to inside of the vehicle. The vehicle approach alert device further includes: a control part configured to read the warning sound source data from the memory to cause the external sound emitting unit to emit the warning sound based on the warning sound source data, and to read the canceling sound source data from the memory to cause the internal sound emitting unit to emit the canceling sound based on the canceling sound source data to be synchronized with the warning sound.

  • Publication number: 20150302213
    Abstract: Security measures taking into consideration significance of handled information is made applicable and prevents security requirement to be set in the system from missing, in system security design. In supporting requirement defining and measures planning, the system as the target of design is indicated divided in a plurality of zones and is classified into a path 420 communicably coupling the zones, a zone boundary 419 being a coupling part between the path 420 and each zone, and an in-zone 418, and has associated and registered to each a security requirement 403 and security measures 413 having measures to be taken divided into levels. The path 420 has also associated a level of transmitted data and the level 409 of the corresponding zone boundary 419 is determined according to the transmitted data level of the path.

  • Patent number: 9000900
    Abstract: A vehicle proximity annunciator device reduces an occurrence of a pop noise without an additional circuit changing an output of a power amplifier. A capacitor is located between a connection point connecting multiple resistances generating a reference voltage and a ground terminal. The capacitor causes a rise-up time of the reference voltage to delay at a start of power supply to a power source terminal. A sound emission signal is increased at substantially a same level of the reference voltage so that a variation of a differential voltage between the reference voltage and the sound emission signal falls in a pre-determined range.
