摘要： An ink jet printhead control circuit is provided. The ink jet printhead control circuit includes at least a nozzle firing circuit and a nozzle firing control circuit. The nozzle firing circuit includes a switch and a heating resistor. The switch and the heating resistor are coupled in series between a power voltage level and a predetermined voltage level. The nozzle firing control circuit is electrically coupled to the nozzle firing circuit, and receives a selection signal and an address signal. When the address signal and the selection signal are enabled, the nozzle firing circuit is controlled to apply the power voltage level to turn on the switch to drive the heating resistor so that droplets of ink are jetted out.

摘要： The present invention provides an omnidirectional wind collection apparatus. The wind collector includes an outer housing with a peripheral wind inlet circumferentially formed therein. An inner housing disposed within the outer housing has an inner surface with a first opening at a lower end thereof to guide the collected wind to a smaller second opening at the top end. The inner surface is curved between the bottom and top openings to form a progressively narrower passage. The configuration of the inner surface creates a Venturi effect such that the wind is accelerated toward the second opening. A wind pass-through portion is formed above the second opening in the inner housing. Based on the Bernoulli effect, the passage of uncollected wind through this portion creates a low pressure region that expedites flow of collected wind through the first and second openings of the inner housing.
