A specially developed CCD in a wire-bonded package used for ultraviolet imaging. A charge-coupled device ( CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology ...
Video camera tubes were devices based on the cathode-ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s. In these tubes, an electron beam was ...

Closed-circuit television ( CCTV ), also known as video surveillance, [1] [2] is the use of closed-circuit television cameras to transmit a signal to a specific place, on a limited set of monitors.
70–90% [1] Self-discharge rate. 10%/month. Cycle durability. 2,000 cycles. Nominal cell voltage. 1.2 V. The nickel–cadmium battery ( Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation Ni–Cd is derived from the chemical symbols of nickel (Ni ...
To make it cost-effective with the state’s new incentives, homeowners now need to install batteries in addition to solar panels, but that can cost an additional $10,000 to $20,000 or more. “It ...
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies ...
A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when charging is complete—depends on the size and type of the ...
