Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in a plurality of spectral bands. Each of the plurality of spectral bands can include an absorptance peak with a spectral bandwidth, a maximum absorptance, and an integrated absorptance peak area within the spectral bandwidth. An attenuation factor obtained by dividing the integrated absorptance peak area within the spectral bandwidth by the spectral bandwidth of the absorptance peak can be greater than or equal to about 0.8 for the absorptance peak in each of the plurality of spectral bands.

Work vehicle and work vehicle control method

The invention relates to a system for evaluating the driving environment of a motor vehicle and for influencing the speed of said vehicle. Said system comprises an electronic control unit, connected to the following: a signal generator which emits a signal that characterises the desired speed for the motor vehicle; a signal generator which emits a signal that characterises the rotational speed of the motor vehicle about its vertical axis; a signal generator which emits a signal that characterises objects situated in the space preceding the motor vehicle in the driving direction, in terms of their distance and orientation in relation to the motor vehicle, said signal representing the speed and/or the distance and/or the angular offset or lateral position in relation to the longitudinal axis of the vehicle equipped with the system; and a signal generator which emits a signal that characterises the speed of at least one wheel of the motor vehicle. The electronic control unit is also connected to at least one control device that influences the driving behaviour, in order to feed said device output signals, derived from the driving behaviour of the target motor vehicle that precedes the vehicle equipped with the system. Said system is characterised in that if a target motor vehicle leaves the detection area preceding the vehicle equipped with the system, the electronic control unit generates a control signal, which limits the current speed or current acceleration of the vehicle equipped with the system for a certain distance to a maximum value that essentially corresponds to the distance between the vehicle equipped with the system and the target motor vehicle, at the moment when the latter left the detection area.

A helmet mounted display (HMD) system comprising a display pod having a light wave optical element. The display pod is designed to be attached to a base plate located above the brow of a helmet using opposing hook and loop-style fastener pads or alternatively, a pair of locking disks. The mounting position of the display pod is adjustable within three degrees of freedom, including lateral positioning along a plane that is co-planar to a mounting surface for the display pod, as well as rotation about an axis that is perpendicular to the mounting surface. The HMD system is adapted to compensate for variations in mounting position using a bore sighting adjustment.

PROBLEM TO BE SOLVED: To constitute a transmission for a working vehicle capable of performing a smooth shift operation and to constitute the working vehicle allowing an easy stop and start at an inclined place. SOLUTION: This transmission for the working vehicle adjusts a traveling speed, performs a shift in a low speed region of the transmission by using at least one variable displacement hydraulic continuously variable transmission 21, and has a normal/reverse rotation mechanism part 22 by a gear for forward and reverse and the change-over clutch 61. When an operation part 7 for operating the normal/reverse rotation mechanism part 23 by forward (F)/neutral (N)/ reverse (R) is operated from a forward position or a reverse position to a neutral position, the hydraulic continuously variable transmission 21 is controlled so that a vehicle speed is zero. When the operation part 7 is operated from the forward position to the reverse position or from the reverse position to the forward position, the hydraulic continuously variable transmission is controlled so that the vehicle speed is zero. Subsequently, a clutch on a side corresponding to a designated position of the operation part 7 is connected. COPYRIGHT: (C)2003,JPO

The synthetic resin lens has a function to generate heat by selectively absorbing infrared rays with wavelengths of 780 to 3000 nm. The synthetic resin lens includes an infrared absorber. Selective absorption of infrared rays allows the synthetic resin lens itself to generate heat and thus the lens of the present invention has the same function as being electrically heated to prevent fogging.
