    • An online payment system uses an electronic check system to make a payment to a merchant on behalf of an online customer. The electronic check system receives a check application request of the customer, creates an electronic check number and a password for the check, outputs the check information to the customer, and stores the check information in the electronic check system. When a merchant system receives an online payment request of the customer, it sends the request to the electronic check system, which then parses out a payment electronic check number and a payment check password from the payment request, verifies the parsed information with the stored check the information, and makes a payment to the merchant. The electronic check system is centralized and shared by multiple merchants. A payment only needs access to the electronic check system, without requiring participation of multiple receipt-acquiring systems of individual merchants.
    • 在线支付系统使用电子支票系统代表在线客户向商家付款。 电子支票系统接收到客户的支票申请请求,创建电子支票号码和支票密码,将支票信息输出给客户,并将支票信息存储在电子支票系统中。 当商家系统接收到客户的在线支付请求时,它将请求发送到电子支票系统,该电子支票系统然后从支付请求中解析出支付电子支票号码和支付支票密码,用存储的支票来验证解析的信息 信息,并向商家付款。 电子检查系统由多个商家集中和共享。 付款仅需要访问电子支票系统,而不需要参与个别商家的多个收据获取系统。

    • A CMOS image sensor that is capable of both voltage- and current-mode operations selects the mode based on the position of mode switches. Each pixel on the imager has a single transistor acting as either source follower for voltage readout, or transconductor for current readout. The two modes share the same readout lines, but have their own correlated double sampling (CDS) units for noise suppression. A current-mode readout technique using a velocity- saturated short-channel transistor may be used to achieve high linearity. An image array may be formed as a mixture of 3 types of pixels with identical photodiodes and access switches. The readout transistors are optimally sized for their designated mode of operation. Alternatively, two readout transistors are provided per pixel, each individually optimized for the desired mode of operation.
    • 能够进行电压和电流模式操作的CMOS图像传感器根据模式开关的位置选择模式。 成像器上的每个像素都具有单个晶体管,用作用于电压读出的源极跟随器,或用于电流读出的跨导体。 两种模式共享相同的读出线,但具有自己的相关双采样(CDS)单元进行噪声抑制。 可以使用使用速度饱和短沟道晶体管的电流模式读出技术来实现高线性度。 图像阵列可以形成为具有相同光电二极管和接入开关的3种像素的混合。 对于其指定的操作模式,读出晶体管的尺寸是最佳的。 或者,每个像素提供两个读出晶体管,每个单独针对所需的操作模式进行优化。

    • A voltage and current mode active pixel sensor for high resolution imaging is presented. The photo pixel is composed of a photodiode and two transistors: reset and transconductance amplifier transistor. The switch transistor is moved outside the pixel, allowing for lower pixel pitch and increased linearity of the output photocurrent. The reset and amplifier (readout) transistors may also be shared among adjacent pixels by the introduction of transfer switches between the photodiodes and the source of the reset transistor and the gate of the readout transistor. The switch transistor outside the pixels provides biasing voltages or currents to the readout transistors to selectively turn them on when readout of the corresponding photodiode is desired and turns the readout transistor off when the corresponding photodiode is not to be read out.
    • 提出了一种用于高分辨率成像的电压和电流模式有源像素传感器。 照片像素由光电二极管和两个晶体管组成:复位和跨导放大晶体管。 开关晶体管移动到像素外部,允许较低的像素间距和增加的输出光电流的线性度。 复位和放大器(读出)晶体管也可以通过在光电二极管与复位晶体管的源极和读出晶体管的栅极之间引入转换开关而在相邻像素之间共享。 像素外部的开关晶体管向读出晶体管提供偏置电压或电流,以在需要读出相应的光电二极管时选择性地将其导通,并且当不读出对应的光电二极管时,使读出晶体管截止。
