Door mirror system

Abstract: The utility model relates to a door mirror system. The door mirror system comprises a shell. An optical door mirror and an image lens are arranged in the shell, and the optical door mirror and the image lens are exposed out of the end of the shell. An inductive sensor used for triggering the image lens is further installed in the shell, and the inductive sensor is exposed out the end of the shell. A control circuit board connected with the image lens and the inductive sensor is also arranged in the shell. The door mirror system has the advantages that the structure is simple, the energy-saving effect is good, and the service life can be prolonged. When a user is at home, the image lens can be closed, and the condition outside a door can be observed through the optical door mirror; when the user goes out, the dynamic condition of a visitor can be observed immediately through images transmitted by the image lens; when a person comes near, a corresponding signal can be detected through the inductive sensor, then the image lens is driven to take photos or shoot, and the images are transmitted to a user terminal.

Inductive detection of target and data processing of sensor signal

Abstract: A method of processing a signal from an inductive sensor to detect an electrically conductive target, such as a pipe or cable below the sea bed, comprises: obtaining a value of a first parameter of the signal for at least two different heights of the sensor above the sea bed; and obtaining information about the response of the sensor to sea water from the values of the first parameter of the signal at the different heights. Information about the sea water response of the sensor may be determined by obtaining values of first and second parameters of the signal for at least two different heights of the sensor above the sea bed in the absence of a conductive target, and making a linear or quadratic fit to the values of the first and second parameters.

Inductive sensor with variable reluctance.

Abstract: of EP0394824The sensor comprises a cup (4) defining a central chamber (6) containing a permanent magnet (11) and two polar parts (12, 13) which project beyond the chamber, and an annular chamber (8) which contains an electrical winding (1) wrapped around a frame (15). The sensor is protected from the environment by the cup (4) and by a moulded-on part (20) which interacts with ribs (18) and (22) in order to insulate the winding (1) contained in the central chamber. Another moulded-on part embeds the electrical connections of the winding to an outer cable (2). Application to a speed sensor for a rotating shaft, particularly for a motor vehicle.

Length or position measurement device has housing with base wall composed of two panels, whereby the sensor is positioned within the first panel and is separated from the measured body by the second panel

Abstract: Length or position measurement device (1) comprises a housing (5) for containing a magnetic or inductive sensor (2). The housing has a base wall (7) formed from two connected panels. The first panel has an opening which receives the sensor which magnetically measures the detected body (9). The second panel is thinner than the first and separates the sensor from the detected body. An independent claim is included for a production method of the measurement devices.
