The embodiment of the invention provides a liquid-crystal display device, and relates to the technical field of liquid-crystal display. By the adoption of the liquid-crystal display device, the resolution and illumination of display are not reduced when transparent display is achieved. A backlight module includes a luminescence part and a light guide plate; after entering the light guide plate ina certain angle range, light transmitted by the luminescence part is totally reflected; a display panel includes a first substrate, a second substrate and a liquid crystal layer; the second substrateis close to the backlight module; the first substrate includes colorful light resistance patterns and light shading patterns, wherein the light shading patterns are used for partitioning the colorfullight resistance patterns and enabling polarized light in a first polarization direction to transmit; the liquid-crystal display device further includes first gratings which are arranged at the side,close to or away from the display panel, of the light guide plate, and the orthographic projections of the first gratings on the light shading patterns are located within the borders of the light shading patterns; the first gratings are used for enabling light which is totally reflected in the light guide plate to be emergent as collimated polarized light, the polarization direction of the collimated polarized light serves as a second polarization direction, and the first polarization direction is perpendicular to the second polarization direction.

A flow measurement sensor accurately outputs signals even when pulsation flow is generated at high engine speed and also when pulsation flow accompanying reverse flow is generated. The flow measurement sensor has a flow measurement element which has a heater resistance pattern on one side of a plate-shaped member, and a bypass passage in which the flow measurement element is disposed, a first outlet through which fluid flowing along the surface of the flow measurement element flows out, and a second outlet through which fluid flowing along the back side of the flow measurement element flows out. The second outlet is positioned at a different location from the first outlet.

The invention discloses an array substrate and a manufacturing method thereof and a liquid crystal panel. According to the method, a color ring resistance pattern is designed, and vent holes not running through the color ring resistance pattern are formed, a passivation layer on the color ring resistance pattern is provided with via holes which are communicated with vent holes for gas in the color ring resistance pattern to escape from. Based on this, the array substrate and the manufacturing method thereof and the liquid crystal panel help to discharge the gas inside the color ring resistance pattern and reduce the risk of bubbles appearing on the liquid crystal panel.

A vehicle-mounting steering switch includes a manipulating knob which is rotatably and pivotally supported on a support member. The support member is fixedly secured to a rear surface of a pad of the steering wheel and, the manipulating knob is protruded into the inside of a space defined between a ring and the pad. A circuit board which is provided with a pair of resistance patterns is mounted on the support member, while a sliding element which is slidable on the circuit board is mounted on the manipulating knob. When a driver performs push or pull manipulation of the manipulating knob with his finger, a relative position of the circuit board and the sliding element is changed so that two kinds of ON signals are outputted. In response to these ON signals, it becomes possible to shift transmission gears in the midst of cruising in a drive range.

Changing resistance patterns in an exercise machine is accomplished by moving a cable pivot point within a channel. The channel may take the form of numerous shapes. Multiple shapes may comprise one continuous channel. The placement of the pivot point and surrounding channel shape dictate the resistance pattern along the range of exercise motion. The pivot point is attached to two cables, one leading to a weight, the other leading to the user of the exercise machine.

A system and method for protecting electrical contact points on a circuit board from tampering and probing. The system includes a protective cover preventing access to electrical contact points on the circuit board. The protective cover includes: at least one nonconductive material layer, a plurality of electrical contacts coupled to the circuit board, and an irregular resistance pattern joined with the at least one layer of nonconductive material and coupled to the plurality of the electrical contacts. The system further includes a controller that is coupled to the plurality of electrical contacts. The system selects two electrical contacts and determines the resistance between the two electrical contacts. The determined resistance is then compared to a baseline resistance determination for the same set of electrical contacts. A security breach can be identified by a change in resistance from the baseline.
