  • Patent number: 9146095
    Abstract: A vibration detection apparatus for, for example, ultrasound/AE, with Fiber Bragg Grating (FBG), is used for elastic wave detection generated by a material impact and ultrasonic defect detection. Disadvantageously, the apparatus cannot detect ultrasound and has degraded performance at variable temperatures and strains. In response, a highly sensitive, small and light vibration detection apparatus is provided. FBG reflection light is lased by using a fiber laser. The intensity of the lased reflection light from the FBG is converted into an electrical signal. Thus, the ultrasound vibration or the like is detected. A vibration detection system includes an optical amplifier 42, an optical circulator 43, and an optical coupler 45. An FBG 44 and an entry/exit port of the optical circulator are connected by an optical fiber. The optical coupler and the optical amplifier are inserted between an entry port and an exit port of the optical circulator. The entry port and the exit port are connected by an optical fiber.

  • Patent number: 8997183
    Abstract: To allow inspecting whether a security check of a planned outgoing email is finished in an outgoing email check system, a check data providing apparatus 2 of an outgoing email check system 100 stores check information distributed from a check information management apparatus 1, appends check data generated based on the check information to a header of a checked planned outgoing email, and transmits the email to an email transmitting apparatus 9. A check data inspecting apparatus 3 stores the check information distributed from the check information management apparatus 1, inspects the check data extracted from the planned outgoing email received from the email transmitting apparatus 9 based on the check information, determines that the transmission is permitted when the check data of the planned outgoing email matches the check information, and determines that the transmission is rejected when the check data does not match the check information.

  • Patent number: 8982648
    Abstract: An antifuse comprised of an NMOS transistor or an NMOS capacitor includes a first terminal coupled to a gate electrode, a second terminal coupled to a diffusion layer, and a gate insulating film interposed between the gate electrode and the diffusion layer. A programming circuit includes a first programming circuit which has first current drive capability and which performs first programming operation and a second programming circuit which has second current drive capability larger than the first current drive capability and which performs second programming operation to follow the first programming operation. In the first programming operation, the first programming circuit breaks down the gate insulating film by applying a first programming voltage between the first terminal and the second terminal. In the second programming operation, the second programming circuit applies a second programming voltage lower than the first programming voltage between the first terminal and the second terminal.

  • Publication number: 20140327752
    Abstract: A vehicle occupancy detection system comprises a vehicle closure panel detector, an imaging system, and a controller. The vehicle closure panel detector detects a closure panel state including opened and closed states of at least one vehicle closure panel of the vehicle and produces closure panel state signals indicative of the closure panel state. The imaging system captures images of a vehicle compartment of the vehicle and produces image signals. The controller determines that the vehicle closure panel has moved from the opened to closed state based on the closure panel state signals, monitors the image signals received from the imaging system from a time that the vehicle closure panel has moved to the closed state and before it again has moved to the opened state, and stores a occupant count representing a number of occupants in the vehicle compartment as determined based on the image signals.
