The invention discloses a scan head's aiming beam exposure solution system, comprising the control circuit of aiming lamp. The control circuit is composed of 5 pin terminals, wherein pinandare the input terminal of gate circuit, and pinis the output terminal of NOT gate circuit; the high level Vcc is connected with pinof the control circuit, and pinof the control circuit is grounded; the pinandare connected with the scanning signal and the field sync signal respectively, and resistor Ris connected with the field sync signal and is grounded. The solution system, compared with the existing scan heads on the market, can completely solve the local overexposure problem of the aiming beam, hugely improve the decoding accuracy, stability, identification rate, decoding speed and power consumption of the scan head hugely, and realize cost-effectiveness easily.

Scan head's aiming beam exposure solution system

The invention internal energy engine is a power machine that makes use of the shape memory effect of shape memory alloy members. The member can be made from a Ni-Ti alloy, for example. It generates great force on a movable part when its transformation is constrained while undergoing temperature changes. The generated high pressure or high speed fluid working medium stream can be used for many practical functions, such as to drive a generator. An important advantage is using waste heat as the energy source. Thus using no fuel and creating no pollution.
