In 2006, Duracell introduced "Power Pix" batteries with NiOx technology, designed to power digital cameras and other high-drain devices for up to twice as long as alkaline batteries. Duracell's professional batteries have been sold in the United States and Europe under the brand name "Procell" (previously "Industrial by Duracell" and "Duracell ...
The first deep-field image to receive a great deal of public attention was the Hubble Deep Field, observed in 1995 with the WFPC2 camera on the Hubble Space Telescope. Other space telescopes that have obtained deep-field observations include the Chandra X-ray Observatory , the XMM-Newton Observatory, the Spitzer Space Telescope , and the James ...
The receiver is a second induction coil in the handheld device that takes power from the magnetic field and converts it back into electric current to charge the device battery. An additional part of the technology is the System Control Communication : Data over Coil (DoC) – the Rx sends feedback to Tx by changing the load seen by the Tx coil.
It can be used to adjust friendly fire, interfaces with tactical fire and predicts the impact of hostile projectiles. Its maximum range is 15 miles (24 km) with an effective range of 11 miles (18 km) for artillery and 15 miles (24 km) for rockets. Its azimuth sector is 90°. It operates in the X-band at 32 frequencies. Peak transmitted power is ...
A deep-cycle battery powering a traffic signal. A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short ...
The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
Fire-resistance rated wall assembly with fire door, cable tray penetration and intumescent cable coating. Passive fire protection (PFP) is components or systems of a building or structure that slows or impedes the spread of the effects of fire or smoke without system activation, and usually without movement.

Button, coin, or watch cells. A button cell, watch battery, or coin battery is a small battery made of a single electrochemical cell and shaped as a squat cylinder typically 5 to 25 mm (0.197 to 0.984 in) in diameter and 1 to 6 mm (0.039 to 0.236 in) high – resembling a button.
