There is disclosed a viewing system coupled to a motor vehicle having a frame having a roof, at least one support, and a body with the at least one support supporting the roof over the body. The system can comprise at least one camera, at least one screen coupled to the support. In addition, each camera is coupled to the at least one support and wherein said at least one screen is in communication with the first set of cameras, wherein said at least one screen displays images presented by the first set of cameras. This device can provide additional view in the blind spot of the vehicle.

A method for processing an electrical signal for an acoustic emission system. The method carried out by the system includes the following steps: a) transmitting a calibration signal to the electroacoustic transducer; b) emitting a sound based on the calibration signal, by the electroacoustic transducer; c) measuring the voltage across the terminals of the load; d) calculating the variation in impedances of the electroacoustic transducer as a function of the variation in frequencies of the calibration signal; e) determining the resonant frequency of the electroacoustic transducer from the variation in calculated impedances; f) selecting a set of acoustic filters in the database based on the determined resonant frequency; and g) applying the set of acoustic filters to the electrical signal in order to process the electrical signal coming from the input.

Hangers, hanger devices, and hanging system are described in the present disclosure for hanging user objects within an interior of a vehicle and for supporting the objects, such as, for example, to prevent the objects from being unrestrained and flying through the air in the event of an accident. In one embodiment, a hanger device includes a shaft element including a shank and a screw component. The screw component has a spiral thread that is adapted to be secured within a threaded bore. The hanger device further includes an annular ring arranged around an outer surface of the shank and a head component attached to an end of the shank. Also, a loop of a flexible material may be adapted to extend from the annular ring.

A vehicle speaker mount for a speaker includes a central bracket and a plurality of elongated portions extending radially outward from the central bracket. each of the elongated portions includes a respective engagement tab at a distal end of the elongated portion with each engagement tab is configured to be releasably connectable with a base of the speaker. Furthermore, the central bracket defines at least one aperture for receiving hardware to connect the mount to a vehicle surface. The vehicle speaker mount may include a threaded ring member and a base ring for securing the vehicle surface therebetween, or a plurality of flanges extending from a base ring for providing additional mounting surfaces.

Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions and a display oriented in the cab to provide information to the operator both while the door is in the opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. The display is positioned to not interfere with the door, door linkages, or operator joystick control.

There is disclosed a viewing system coupled to a motor vehicle having a frame having a roof, at least one support, and a body with the at least one support supporting the roof over the body. The system can comprise at least one camera, at least one screen coupled to the support. In addition each camera is coupled to the at least one support and wherein said at least one screen is in communication with the first set of cameras, wherein said at least one screen displays images presented by the first set of cameras. This device can provide additional view in the blind spot of the vehicle.

A shading device for a vehicle, comprising a dimming glass plate capable of changing a light transmittance thereof, wherein the dimming glass plate is provided at a portion of a vehicular window glass to separate an interior of vehicular compartment from outside of the vehicular compartment or provided at a portion of a surface of the vehicular window glass that faces inside of the vehicular compartment; a display apparatus formed of a light transmitting material and disposed at a surface of the dimming glass plate that faces inside of the vehicular compartment, with a display portion facing inside the vehicular compartment; an image pickup device to capture an area outside of a vehicle to generate image pickup data, wherein the area is at an opposite surface on the dimming glass plate, the opposite surface being opposite a surface on which the display apparatus is provided; a data processing circuit to generate display image data to be displayed on the display portion based on the image pickup data generated by the image pickup device; and a switch to change light transmittance of the dimming glass plate.

A display control device includes a processor; and a non-transitory computer-readable medium having stored thereon executable instructions that, when executed by the processor, cause the display control device to function as: an obstacle identifying part that identifies an obstacle area; a driver information acquiring part that acquires driver information; a blocked area identifying part that identifies a blocked area based on driver information; a blocked area ratio calculating part that calculates a blocked area ratio; and a display controlling part that controls the image on the displaying part. The display controlling part is configured to display a driver's point of view image obtained by converting a viewpoint of the image captured by the imaging part based on the driver information when the blocked area ratio equals to a predetermined value or higher; and not to display it when the blocked area ratio is less than the predetermined value.

A method for localizing a sensor in a vehicle includes using a first sensor mounted on a vehicle to capture at least one image of a moveable element of the vehicle, the moveable element having a predetermined spatial relationship to a second sensor mounted on the vehicle, the moveable element being moveable relative to the first sensor; determining a spatial information on the moveable element on the basis of the at least one image; and localizing the second sensor on the basis of the spatial information by a transformation rule representing the predetermined spatial relationship between the moveable element and the second sensor.
