摘要： An image sensor system comprises an array of pixels. Each of these pixels includes a light sensitive element that generates a pixel signal that is indicative of the amount of light received by that pixel. A comparator then compares the pixel signal to a reference signal and generates a strobe signal in response to this comparison, while a global counter generates a count across a shutter period. Finally, an array of memory elements is provided. Each of these memory elements stores a count from the global counter in response to receiving the strobe signal from the corresponding pixel of the array of pixels. As a result, the array of pixels has relatively little logic functionality. Each pixel need only contain the light sensitive element and the comparator. Thus, the system can provide a good fill factor. Further, the global counter can be shared across the entire memory array. It is most applicable to implementation in CMOS technology.

摘要： A method for loading and unloading substrates on a drum of an imaging engine is applicable to the loading of plates in a platesetter. The method comprises unclamping a trailing edge of a first substrate of the drum and clamping a header of a second substrate to the drum. The order in which these two steps are performed is not critical to the invention. For example, the clamping and unclamping can happen simultaneously. Alternatively, the unclamping of the trailing edge can occur before the clamping of the header, or visa versa. In any case, the drum is then rotated to eject the first substrate from the drum while installing the second substrate on the drum. The notion here is that, as the drum is rotated, one substrate is being ejected while a second substrate is being installed on the drum. Thereafter, the header of the first substrate is unclamped and the trailing edge of the second substrate is clamped to the drum. The method is directed to decreasing the cycle time and thereby increasing throughput in a substrate exposure system, such as a platesetter or imagesetter. It decreases cycle time by optimizing the loading and unloading of substrates.

摘要翻译： 用于在成像引擎的鼓上装载和卸载基板的方法适用于在制版机中装载板。 该方法包括松开滚筒的第一基底的后缘并将第二基底的头部夹紧到滚筒上。 执行这两个步骤的顺序对于本发明不是关键的。 例如，夹紧和松开可以同时发生。 或者，后缘的松开可以在夹头之前发生，反之亦然。 在任何情况下，然后使滚筒旋转以将滚筒上的第二基底安装在滚筒上，从而将滚筒推出。 这里的概念是，当滚筒旋转时，一个基板被弹出，而第二个基板被安装在滚筒上。 此后，第一基板的头部被松开，并且第二基板的后缘被夹紧到滚筒。 该方法旨在减少循环时间，从而增加基板曝光系统（例如制版机或成像机）中的生产量。 它通过优化底物的装载和卸载来缩短循环时间。

摘要： A nip mechanism for a substrate transfer system allows the nip mechanism to be actuated such as opened and/or closed by the drive motor for the nip mechanism. As a result, the need to operate the nip mechanism pneumatically, for example, can be avoided. Essentially, the drive motor now performs a dual role, i.e., both driving the nip rollers and also opening and closing the nip mechanism. The nip mechanism comprises a roller separation mechanism and a one-way clutch for engaging the roller separation mechanism when the drive motor is driven in the second direction. In the present implementation, this roller separation mechanism comprises a cam that pushes the first nip roller and the second nip roller away from each other. A cam limiter can be used to prevent over-rotation of this cam.

摘要： An apparatus is provided for positioning a plurality of cassettes within an automated printing plate handler. In a plate handler, a plurality of cassettes each contain a supply of printing plates for delivery to an automatic plate-recording device. The apparatus includes a separate support table for supporting each of the plurality of cassettes within the plate handler and an elevator device for moving each of the support tables along a vertical axis of the automated plate handler. The automated plate handler is configured to automatically position a selected cassette in a first position to facilitate removal of the cassette from the handler. The plate handler further includes a platform, which substantially forms an extension of the support table supporting the selected cassette in the first position. The platform provides a second position, at which the selected cassette is to be one of, loaded or unloaded. The selected cassette may be filled with a new supply of plates on the platform or the selected cassette may be removed from the platform and replaced by a another cassette.

摘要： A calibration system for a platesetter or imagesetter is applicable to systems that have a media drum and a carriage, including a light source and a spatial light modulator for selectively exposing the media that is held against the drum. The invention can be applied to internal or external drum systems. The calibration system comprises a calibration sensor that is scanned relative to the spatial light modulator. The controller then analyzes the response of the calibration sensor to generate calibration information that is used to configure the spatial light modulator. The use of this calibration sensor allows for job-to-job calibration of the spatial light modulator, in one example, that ensures the generation of a high quality images, without banding, for example, on the media. This calibration system is also used to detect a best focus position for projection optics by measuring a contrast ratio between exposure and dark levels for various focus settings. It selects the best focus position in response to the contrast ratio.

摘要： A plate cassette loader for a platesetter comprises a cassette holder for receiving a cassette, containing a stack of plates. A cassette inverter then rotates this cassette to a feed position in which the plates can be fed into the imaging engine of the platesetter. In this way, the somewhat unwieldy process of loading plates into the imaging engine is handled by the cassette inverter, in combination with the fact that the stack of plates, contained in the cassette, can be loaded in one step, rather than requiring the feeding of individual plates by a dedicated operator.
