Patent number: 7205776Abstract: Whether a human body is touching or not is detected highly accurately at high speed. Switch SW1 is turned on to charge condenser Ca by power supply Vcc. The switch SW1 is turned off to transfer the electric charge charged in the condenser Ca to condensers Cs and Cx. The switches SW2 and SW3 are repeatedly turned on and off for a predetermined short time, and thus the electric charge charged in the condenser Ca is slowly discharged through resistor R. The unknown charging voltage Vx of the condenser Cx is compared with the reference voltage Vref by comparator Comp, and the unknown capacitance of the condenser Cx is computed based on the number of times to count turning on and off until it is smaller than the reference voltage Vref. When the computed unknown capacitance of the condenser Cx is the value near the capacitance of a human body, it is determined that a human body is touching. The invention can be applied to a touch sensor.Type: GrantFiled: September 7, 2005Date of Patent: April 17, 2007Assignee: Omron CorporationInventors: Masahiro Kinoshita, Hideyuki Urata, Hideshi Tsugui, Yoshihiro Tanabe

Publication number: 20050143887Abstract: In a vehicle driving assist system, an external environment recognition unit detects a 3-D obstacle inhibiting the driving direction of the vehicle based on an image captured by a stereo camera and determines whether the image ahead of the vehicle is in a condition that makes visual perception of the 3-D obstacle difficult. A controller calculates a required alarm working distance between the vehicle and the 3D obstacle, at which an alarm unit is worked when the vehicle approaches the 3D obstacle, and a required brake operating distance, at which a brake is operated by a brake applying unit, based on a vehicle traveling speed. If it is determined that an external environment is in a condition that makes visual perception difficult, the required working and operating distances are extended by predetermined values to set the working and operating timings earlier.Type: ApplicationFiled: December 17, 2004Publication date: June 30, 2005Applicant: Fuji Jukogyo Kabushiki KaishaInventor: Masahiro Kinoshita
