摘要： Solid-state image sensors, in general, comprise a photodetector for detecting radiation from the image and converting the radiation to charge carriers, and transfer means for carrying the charge carriers to an output circuit. One type of solid-state image sensor uses a CCD as both the photodetector and the transfer means. The solid-state image sensor generally includes a plurality of the CCD's arranged in spaced parallel relation to form an array. The image sensor of this disclosure utilizes only one antiblooming lateral overflow barrier. The excess signal charge of phase 1 flows into the preceding phase 2 and is saved. This eliminates the overflow barrier of phase 1 so that blooming protection is via the overflow barrier of the preceding phase 2. This results in an image sensor with blooming protection and increased charge capacity.

摘要： A drop-on-demand liquid emission device, such as for example an ink jet printer, includes a member movable through a path for driving liquid from the device, wherein the speed at which the member moves is reduced over the time period that liquid is being expelled. During that time period, a portion of the liquid flows through a passage away from the nozzle orifice. According to a feature of the present invention, a variable flow restrictor increases the resistance to flow through the passage during the time period that liquid is being expelled; thereby tending to compensate for the reduction of the liquid-expulsion force over the time period. The result is a reduction of undesirable satellite droplets following a main drop.

摘要： A method for manufacturing a mechanical grating device is presented. The device consists of a plurality of parallel-suspended ribbons that are deformed using, for example, an electrostatic force to actuate alternate ribbons. Actuation is a deformation of the ribbon resulting from an applied voltage to affect the height of the ribbons above a substrate. The method for manufacturing a mechanical gating device comprises the steps of: providing a spacer layer on top of a protective layer which covers a substrate; etching a channel entirely through the spacer layer; depositing a sacrificial layer at least as thick as the spacer layer; rendering the deposited sacrificial layer optically coplanar by chemical mechanical polishing; providing a tensile ribbon layer completely covering the area of the channel; providing a conductive layer patterned in the form of a grating; transferring the conductive layer pattern to the ribbon layer and etching entirely through the ribbon layer; and removing entirely the sacrificial layer from the channel.

摘要： By designing pixels with highly transparent ITO electrodes and asymmetric gates such that as much light as possible falls upon a region covered by an ITO electrode, light sensitivity is increased. Impurity diffusion from the ITO electrode into the silicon below is prevented by employing an Oxide/Nitride/Oxide stack as a dielectric. Employing at least some polysilicon electrodes with ITO electrodes is desirable to allow entrance passages through which hydrogen passivation can be accomplished. The pixel architecture can be designed to increase sensitivity further by other design choices. The first of these choices is to incorporate a lenslet on each pixel such that as much as possible of the light falling on the pixel is made to pass through the portion of the pixel covered with ITO. The second method is for color CCD sensors with color filter patterns, such as the "BAYER" color filter pattern to name just one, to have the overlap of the color filters, which does not allow light transmission, to occur over the less sensitive area of the pixel, which is the area covered with the polysilicon electrode. For proper operation a slight modification of the vertical clock timing is needed.
摘要翻译： 通过设计具有高度透明的ITO电极和非对称栅极的像素，使得尽可能多的光落在由ITO电极覆盖的区域上，光敏度增加。 通过使用氧化物/氮化物/氧化物层作为电介质来防止从ITO电极向下面的硅的杂质扩散。 使用具有ITO电极的至少一些多晶硅电极是期望的，以允许可以实现氢钝化的入口通道。 像素架构可以通过其他设计选择进一步提高灵敏度。 这些选择中的第一个是在每个像素上并入一个小透镜，使得落在像素上的光尽可能地穿过被ITO覆盖的像素的部分。 第二种方法是用于具有彩色滤光片图案的彩色CCD传感器，例如“BAYER”彩色滤光片图案，其名称仅为一个，以便在较不敏感的区域上发生不允许透光的滤色器的重叠 的像素，其是被多晶硅电极覆盖的区域。 为了正确操作，需要稍微修改垂直时钟时序。

摘要： A method and system for light beam communication between a camera and a computer is provided by adapting an existing light beam auto-focus system of a conventional automated camera, such as a conventional automated film-based camera or a conventional automated electronic camera, and by adapting a conventional computer to provide a light beam communication linkage with the adapted camera. The light beam auto-focus system of such automated cameras is modified to include a mode selector providing a selection of the conventional light beam auto-focus mode and alternatively for selection of a light beam communication mode. The camera has a microprocessor and an erasable electrically programmable read-only memory (EEPROM). In the light beam communication mode, a light beam emitter driver circuit and a light beam sensor timing circuit and signal processor are provided. A conventional computer, for example, a desktop computer or a laptop computer, is adapted to receive and to transmit optically encoded digital signals whereby a computer-based light beam sensor and light beam emitter have an optical spectrum overlapping with the optical spectrum of the camera-based light beam emitter and light beam sensor. Light beam communication is initiated by suitable commands provided by a camera user to the computer. The camera microprocessor is responsive to such commands, and that response is transmitted by the camera-based light beam emitter back to the computer-based light beam sensor.
