  • Patent number: 8655542
    Abstract: An electronic tag is attached to a filter cartridge, which includes a filter. The electronic tag stores individual product information of the filter and wirelessly transmits the individual product information. A wireless receiver device is installed to a predetermined location of a vehicle, which is other than the filter cartridge and receives the individual product information transmitted from the electronic tag. A diagnostic device diagnoses whether the individual product information is received by the wireless receiver device or whether the filter cartridge installed in the vehicle has a desired filtering performance based on contents of the individual product information received by the wireless receiver device.

  • Patent number: 7891337
    Abstract: A fuel injection system designed to learn the quantity of fuel sprayed actually from a fuel injector into an internal combustion engine. When the engine is placed in a given learning condition, the system works to spray different quantities of the fuel for different injection durations in sequence to the engine through the fuel injector to collect a plurality of data on the quantity of the fuel sprayed actually from the fuel injector. The system analyzes the corrected data to determine an injection characteristic of the fuel injector, which may have changed from a designer-defined basic injection characteristic of the fuel injector, and uses the injection characteristic in calculating an injection duration or on-duration for which the fuel injector is to be opened to spray a target quantity of fuel.

  • Patent number: 7818479
    Abstract: A device interface circuit unit transfers a command and data in packet format between the unit and the host. A transport layer is provided with a receive FIFO, a command detection circuit and a send FIFO, and an application layer is provided with a receive task file register and a send task control file register. An available time is generated for each break point of a packet during data transfer in order to receive another command packet from the host. When the command packet is received from the host in the available time during data transfer, the data transfer is suspended and the received command is decoded to execute a process for continuing or canceling the data transfer, after which the data transfer is resumed.
