摘要： A solvent dispensing mechanism is fluidically coupled to create a substantially uniform wet region of a belt surface scrubber. Mechanisms for selectively engaging and disengaging the scrubber ensure free belt travel during flexible material transport and the cleaning of both surfaces during cleaning cycles. The system includes consumable piece-part elements for refurbishing and remanufacturing.

摘要： A multi-tiered, multi-faceted, anti-flicking wiper scraper system cleans an inkjet printhead wiper without flicking or splattering ink residue onto other components in an inkjet printing mechanism. This system includes a scraper apparatus supported by a service station frame to contact the wiper through relative motion of the wiper and scraper apparatus. The scraper apparatus may take the form of two scraper bars which extend into the path of the wiper, with the first scraper bar being shorter than the second scraper bar, and with the first scraper bar being rigidly or pivotally supported by the frame. The scraper apparatus may be a unitary body defining two ramped wiping surfaces joined at an apex portion of the body, or a body having a scraping surface covered with a series of ridges. A method is also provided to clean ink residue from an inkjet printhead.

摘要翻译： 多层，多面，防滑刮擦刮刀系统清洁喷墨打印头擦拭器，而不会在喷墨打印机构中将墨水残留物溅到或喷溅到其他部件上。 该系统包括由维修站框架支撑的刮刀装置，以通过刮水器和刮刀装置的相对运动来接触刮水器。 刮刀装置可以采取两个刮板的形式，其延伸到刮水器的路径中，其中第一刮刀杆比第二刮刀杆短，并且第一刮刀杆被框架刚性地或可枢转地支撑。 刮刀装置可以是整体，其限定在主体的顶点处连接的两个倾斜的擦拭表面，或具有覆盖有一系列脊的刮削表面的主体。 还提供了一种从喷墨打印头清洁墨水残余物的方法。

摘要： An infrared detector has a multi-layer structure to simultaneously detect IR energy in different spectral bands without changing polarity of a bias imposed across the detector. Two absorption layers are separated by a barrier layer that imposes an electrical potential barrier to one of the absorption layers. Under low bias in one direction, only one layer generates a photocurrent. Under a higher bias in the same direction, both layers generate a photocurrent. Additional absorption layers may be added to detect additional bands of energy, where the additional absorption layers generate photocurrent under a bias in another direction. Two, three, and four band detection is disclosed. Where absorbing layers within a single unit cell absorb under different bias direction, the barrier layer between those different bias direction layers suppresses a diffusing electron current. A method for detecting and resolving energy absorbed in two, three, and four different energy bands is also provided.
