Abstract: The invention relates to a steering device for vehicles, in particular forklifts, for carrying out a steering movement of the drivable vehicle on a surface by manual operation by a vehicle driver, wherein the steering device is attached to or in an armrest of a vehicle seat, wherein the steering device comprises at least one rotatable wheel element which can be at least partially grasped on the circumference by the fingers of a hand of the vehicle driver placed on the steering device and can be rotated about an axis of rotation for a steering movement.

Abstract: A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

Abstract: The touch-operating input device is configured so that when the control circuit turns on the main light source corresponding to each of the translucent operation buttons that can be operated, the control circuit, on condition that the translucent operation button corresponding to the main light source that is turned on is operated, turns off the sub-light source corresponding to the translucent operation button that is turned on simultaneously with the main light source. Ease of operation is increased by enabling the operator to distinguish operated translucent operation buttons from translucent operation buttons that have not been operated according to whether or not the main light sources are lit.

Abstract: A system for communicating over a power cable has a power line connected to a power source at one end, a switch mode transformer connected to the power line at the other end for transforming voltage received from the power source through the power line, modulation of the switch mode transformer, and a receiver situated at the power source end and adapted to detect and process ripple signals from the switch mode transformer propagated on the power line.

Abstract: A system includes a layer, a shaftless stepper motor, a lighting element, an input magnet, an output magnet, and a pointer. The layer includes first and second opposed sides. The shaftless stepper motor is disposed on the first opposed side of the layer. The lighting element is disposed on the first opposed side of the layer. The input magnet is disposed on the first opposed side of the layer and is connected to the shaftless stepper motor. The output magnet is disposed on the second opposed side of the layer. The pointer is connected to the output magnet. The input magnet connected to the shaftless stepper motor moves, through magnetism, the output magnet and the connected pointer, and the lighting element transmits lights to light the pointer.

Abstract: A vehicle display with a housing having a gauge port, an interior wall around the gauge port, and an appliqué port extending from an exterior side of the vehicle display and intersecting the gauge port. A light source provides light into the gauge port and directs the light outwardly from a front side of the housing. An appliqué has a first locking feature. The appliqué port at least partially receives the appliqué between the front side of the housing and the light source. The light from the light source illuminates a portion of the appliqué. The first locking features releasably engages a second locking feature.

Abstract: A meter unit includes pointer light sources, main mark light sources, and sub-mark light sources. The pointer light sources, the main mark light source, and the sub-mark light sources are turned on with time lags after an ignition (IG) switch is turned to an ON position. Therefore, pointers, main marks, sub-marks of the meter unit are illuminated with time lags. This makes outlines of the pointers, the main marks, and the sub-marks sharp. As a result, not only the pointers but also the marks and the sub-marks of the meter unit outstand from each other.

Abstract: A display apparatus includes a display apparatus main body, illuminating component, and transparent plate. The display apparatus main body has a flat screen. The illuminating component is formed into a frame to, correspond to a peripheral edge portion of the screen, and is arranged in tight contact with the screen. The transparent plate is arranged on an opposite side of the screen in tight contact with the illuminating component to face the screen. The illuminating component entirely seals a peripheral portion of a gap between the screen and transparent plate.

Abstract: Organic tracers are employed to monitor the movement of subterranean fluids. These organic tracers are (a) stable at elevated temperatures, (b) capable of being detected at low concentrations, and/or (c) not adversely affected by the make-up of at least one subterranean formation. In addition, a plurality of these tracers can be measured by a single analytical technique.
