Abstract
CMOS active pixel sensors (APS) have performance competitive with charge-coupled device (CCD) technology, and offer advantages in on-chip functionality, system power reduction, cost, and miniaturization. This paper discusses the requirements for CMOS image sensors and their historical development, CMOS devices and circuits for pixels, analog signal chain, and on-chip analog-to-digital conversion are reviewed and discussed.

Method and system for a set of network appliances which can be connected to provide enhanced collaboration, scalability, and reliability

TL;DR: In this paper, a network-enabled appliance may aid the remote monitoring of various measured data, such as a variable or set of variables and output the data upon request, and the appliance may issue alarms, alerts, warning and other notifications when a variable matches a setpoint or undergoes a specified change, deviation, and/or fluctuation.

Active Pixel Sensors: Are CCD's Dinosaurs?

TL;DR: ActivePixel Sensor (APS) as mentioned in this paper is a detector array technology that has at least one active transistor within the pixel unit cell, which eliminates the need for nearly perfect charge transfer, which makes CCD's radiation'soft' and difficult to use under low light conditions, difficult to integrate with on-chip electronics, difficulty to use at low temperatures, and difficulty to manufacture in non-silicon materials that extend wavelength response.
