摘要： An inkjet printhead addressing and firing design which minimizes voltage drop differential occurring on a power bus which supplies power to fire individual ink jets due to current loads needed to fire the individual ink jets. The voltage drop differential can be reduced in part by firing a group of individual jets which are spaced out over the entire length of the array instead of firing a group of adjacent jets. Spacing of the firing jets will insure that less than an entire amount of current needed to fire a group of jets will be needed in the center of the bus. Reducing the amount of current needed to travel the length of the bus reduces the voltage drop differential on the bus caused by current conduction along the bus.
摘要翻译：一种喷墨打印头寻址和点火设计，其最小化电力总线上发生的电压降差异，该功率总线由于为单个喷墨喷射所需的当前负载而提供消耗个体喷墨的电力。部分地可以通过点燃在阵列的整个长度上间隔开的一组单独的射流而不是发射一组相邻的射流来降低电压差微分。发射喷气式飞机的距离将确保在公共汽车中心需要少于整个喷射一组喷气机所需的电流。降低行驶长度总线所需的电流量减少了总线上电流传导引起的总线上的电压差差。

摘要： A method in which several high voltage chips may be packaged within a single, typically low voltage plastic package. The high voltage chips are packaged to remain electrically isolated from each other to avoid undesirable side effects such as arcing between the chips but able to share electronic data and communicate with each other electronically through their input and ouput nodes. Due to the unique packaging method, the typically low voltage plastic packaging can be made to withstand operating voltages up to 35 times greater than previously attained by such low voltage plastic packaging.

摘要： A layout of a MOSFET current driver is disclosed which improves the fabrication yield and the current drive capability over that of the prior art while keeping the layout area the same as the prior art. In this design, the gate is laid out to have a lateral serpentine pattern rather than a vertical serpentine pattern to create a larger gate in order to improve the current drive capability. In addition, the contacts for the drain and the contacts for the source are removed from the gate layout area which facilitates condensing the gate layout and increasing the size of the gate. Also, this design has only two metal strips: one for the drain and one for the source of the MOSFET current driver. The two metal strips substantially overlap the serpentine patterned gate. Having only two metal strips reduces the spaces between the metal strips to one space thereby reducing the probability of having a short or a defect and improving the fabrication yield.
摘要翻译：公开了MOSFET电流驱动器的布局，其提高了现有技术的制造产量和电流驱动能力，同时保持布局面积与现有技术相同。在这种设计中，门被布置为具有侧向蛇形图案，而不是垂直的蛇形图案以产生更大的栅极，以便提高电流驱动能力。此外，用于源极的漏极和触点的触点从栅极布局区域移除，这有利于栅极布局的集中和增加栅极的尺寸。此外，该设计只有两个金属条：一个用于漏极，一个用于MOSFET电流驱动器的源极。两个金属条基本上与蛇形图案化的栅极重叠。只有两个金属条将金属条之间的空间减小到一个空间，从而减少了短或缺陷的可能性并提高了制造成品率。

摘要： An acoustic inkjet printhead utilizes a pulse width modulation to control droplet size or ejection velocity. An individual control pulse controls the duration and the time a RF signal is applied to each transducer. To modify the RF signal of each transducer, the pulse width of each control signal can be modified according to a predetermined correction data. The rising edge of the control data is delayed according to the correction data while the falling edge is kept the same.

摘要： An improved optically controlled power supply regulator in which an optoisolator transistor is controlled by an input light emitting diode replaces an optically controlled power supply regulator with a light emitting diode controlled with a light dependent resistor. The optically controlled power supply regulator utilizes a capacitor and a resistor to reduce loop response oscillation in order to prevent the optically controlled power supply regulator from being shut down on a system board.
