  • Publication number: 20200010060
    Abstract: An automatic brake subsystem (24) includes second accumulators (25F, 25R), a front second line (28) and a rear second line (29), second brake valves (30F, 30R), a first solenoid switching valve (32), first shuttle valves (33F, 33R), and a controller 37. A second solenoid switching valve (34F) and a pressure sensor (35F) are provided in the front second line (28), and a second solenoid switching valve (34R) and a pressure sensor (35R) are provided in the rear second line (29). In a case where it is determined that each of the second brake valve (30F, 30R) is not performing normally based upon a pressure of a hydraulic fluid detected by each of the pressure sensors (35F, 35R) and an operating signal supplied to the first solenoid switching valve (32) or each of the second brake valves (30F, 30R), a controller 37 performs control to switch each of the second solenoid switching valves (34F, 34R).

  • Patent number: 10514648
    Abstract: An exposure device irradiates a photoconductor with light on the basis of an exposure signal and thereby forms an electrostatic latent image. A toner amount calculating unit (a) determines a distribution pattern of the electrostatic latent image on the basis of the exposure signal, (b) determines an electric field variation level of a target pixel, (c) determines an electric field intensity of the target pixel on the basis of a value of the target pixel in the distribution pattern and the electric field variation level, and (d) determines a toner consumption amount corresponding to the electric field intensity. Further, using spatial filters independently of each other in a primary scanning direction and in a secondary scanning direction, the toner amount calculating unit determines the electric field variation level on the basis of (a) the distribution pattern or (b) the exposure signal.

  • Patent number: 10509508
    Abstract: Provided is a touch sensing circuit configured to sense an approach of a conductive object toward a sensor capacitor through measuring a sensor response signal generated by the sensor capacitor in response to a sensing wave signal applied to the sensor capacitor. The touch sensing circuit is connectable to a conversion circuit and a touch detection circuit. The conversion circuit calculates a response signal vector for a frequency component of the sensing wave signal by converting the response signal into a frequency domain representation. The touch sensing circuit includes a baseline vector manager circuit holding a baseline vector and a vector subtraction circuit, and calculates a delta vector which is the vector difference between the baseline vector and the response signal vector received from the conversion circuit. The touch detection circuit detects an approach of a conductive object towards the sensor capacitor on the basis of the calculated delta vector.
