摘要： A microdeposition system and method includes a head with a plurality of nozzles. A controller generates nozzle firing commands that selectively fire the nozzles to create a desired feature pattern. Configuration memory stores voltage waveform parameters that define a voltage waveform for each of the nozzles. A digital to analog converter (DAC) sequencer communicates with the configuration memory and the controller and outputs a first voltage waveform for a first nozzle when a nozzle firing command for the first nozzle is received from the controller. A resistive ladder DAC receives the voltage waveforms from the DAC sequencer. An operational amplifier (opamp) communicates with the resistive ladder DAC and amplifies the voltage waveforms. The nozzles fire droplets when the voltage waveforms received from the opamp exceed a firing threshold of the nozzle.

摘要： A dispenser for dispensing a liquid includes a chamber holding a supply of liquid, an annular conduit substantially filled with liquid from the chamber, and a thermoelectric transducer near one end of the annular conduit. Upon application of electrical current to the thermoelectric transducer, the transducer operates to cause boiling of a quantity of liquid in the annular conduit. Expansion of a resulting bubble forces liquid out the end of the annular conduit. The dispenser may include battery powered electronic control circuit that includes a supercapacitor. The liquid may be dispensed in periodic bursts. In one application, the dispenser is especially suited to automatically and unobtrusively dispense a fragrance, perfume, or other personal care liquid worn by a person. In some applications, the dispenser may be worn on or under an article of clothing, or attached to an article of jewelry.

摘要： An improved electrographic writing head employs interleaved arrays of writing nibs and small geometry, high impedance, thick film resistors and semiconductor driver circuits fabricated on separate glass epoxy substrates disposed in adjacent back to back relation. The writing head achieves significant savings in manufacturing costs by using low cost printed circuit and thick film technology. Power consumption may be reduced by more than half over prior art devices due to the high impedance of each thick film pull up resistor coupled with an associated writing nib. A ground plane is disposed between the adjacent substrates and between adjacent arrays of writing nibs. The ground plane prevents electrical interaction between the substrates and prevents the formation of parasitic nib-to-nib capacitance by shunting parasitic capacitance currents to ground. The ground plane thus reduces the possibility of flaring and substantially eliminates inadvertent writing by adjacent nibs.
摘要翻译： 改进的电子写入头使用以相邻的背靠背关系布置的分开的玻璃环氧树脂基底上制造的写入笔尖和小几何形状，高阻抗，厚膜电阻器和半导体驱动器电路的交错阵列。 写头通过使用低成本印刷电路和厚膜技术实现了制造成本的显着节省。 由于与相关联的写入笔尖耦合的每个厚膜上拉电阻器的高阻抗，功耗可以比现有技术的器件减少一半以上。 接地平面设置在相邻基板之间和相邻的写笔尖之间。 接地平面可防止衬底之间的电气相互作用，并通过将寄生电容电流分流到地来防止形成寄生的笔尖至笔尖电容。 因此，接地平面因此减少了扩张的可能性，并且基本上消除了相邻笔尖的无意写入。

摘要： A device for providing extremely accurate tracking and control of a continuous belt or web driven by at least one roller such as a paper transport belt for an electrostatic plotter, printer or the like includes a method for cancelling out the effect of belt edge irregularities by sampling the irregularities in the edge of a belt at precise positional intervals for an initial rotation of the belt and storing the sampled values as elements in a reference array. The reference array is corrected to include an error component representative of linearly increasing measurement of error for each of said array elements due to lateral shifting of the belt. During subsequent operation, the lateral displacement of the belt is continuously scanned for each of said positional intervals with respect to a corresponding element of the array. A corrective feedback mechanism generates corrective feedback signals representative of a desired belt position for each of said positional intervals to thereby maintain the belt on an ideal axis of travel. In a paper transport system incorporating this device, a transport belt can be corrected within a fraction of a belt revolution, irrespective of direction, and paper or another recording medium can be accurately registered on repeated writing passes to within 0.0005 inches.
