Patent number: 8721027Abstract: A discharge amount calculating device for calculating the discharge amount of a fluid from a fluid ejecting apparatus is disclosed, in which the fluid ejecting apparatus is capable of ejecting at least one fluid onto a target at a discharge amount of multiple stages. The discharge amount calculating device includes a plurality of calculating sections that calculate the discharge amount of the fluid at the respective multiple stages based on a bit number of input data, a desired number of calculating sections not exceeding 2n being provided, in which n is a positive integer, and a converting section that converts the inputted discharge amount data of n bits into bit number data corresponding to any one of the plurality of calculating sections, and outputs the converted data to the plurality of calculating sections.Type: GrantFiled: September 27, 2011Date of Patent: May 13, 2014Assignee: Seiko Epson CorporationInventors: Shuji Otsuka, Fumitaka Sugimoto

Patent number: 8686833Abstract: The control system has a structure in which sensor apparatuses each having a data communication function are connected to an electronic control apparatus through a common communication line, and the sensors of the sensor apparatuses are connected to the electronic control apparatus through separate individual signal lines to transmit sensor signals to the electronic control apparatus. The electronic control apparatus is configured to, prior to transmitting communication data to one of the sensor apparatuses through the communication line, set the signal line connected to the selected sensor apparatus in a state in which the voltage of the signal line is outside a variation range corresponding to a voltage range of the sensor signal, and set the signal lines connected to the other sensor apparatuses to each of which the communication data is not addressed in a state in which the voltage of the signal line is within the variation range.Type: GrantFiled: June 21, 2011Date of Patent: April 1, 2014Assignee: Denso CorporationInventors: Toshikazu Hioki, Housyo Yukawa, Masayuki Kaneko, Fumitaka Sugimoto, Hirohumi Isomura

Patent number: 8451091Abstract: The present invention provides, as one aspect, a control system having sensor units and an electronic control unit. The electronic control unit includes a transmission controlling means which sets a signal line connected to the sensor unit, which is a destination of communication data, to a first state, sets the signal line connected to the sensor unit, which is not the destination, to a second state, and transmits the communication data to the destination via a communication line. The sensor unit includes a reception controlling means which determines a state of the signal line connecting a sensor to the electronic control unit. When determining that the signal line of the sensor unit is in the first state, the reception controlling means receives the communication data and performs a predetermined process. When determining that the signal line is in the second state, the reception controlling means discards the communication data.Type: GrantFiled: December 15, 2009Date of Patent: May 28, 2013Assignee: Denso CorporationInventors: Toshikazu Hioki, Takeshi Iwai, Housyo Yukawa, Fumitaka Sugimoto, Hirofumi Isomura
