A digital photo frame (also called digital media frame) is a picture frame that displays digital photos without the need to print them or use a computer. The digital photo frame may also be able to display the photos on a TV set.

Flash memory combines a number of older technologies, with the low cost, low power consumption and small size made possible by recent^[update] advances in microprocessor technology. The memory storage is based on earlier EPROM and EEPROM technologies. These had very limited capacity, were very slow for both reading and writing, required complex high-voltage drive circuitry, and could only be re-written after erasing the entire contents of the chip.

A wallet generally has one or more currency pockets; in some cases, there may also be a money clip. Wallets usually have one or more pockets for storing credit card or identification cards, which may be oriented vertically or horizontally.

Wallets may also have an identification pocket, which facilitates the display of a regularly-used piece of identification such as workplace ID or a bus pass, by housing it within a transparent "window". A wallet may also have photo pockets, which are designed to hold a collection of small personal photographs. A wallet may also have a small pouch for coins or keys.

A cap is a form of headgear. Caps have crowns that fit closer than hats and have no brim or only a visor. They are typically designed for warmth and, when including a visor, blocking sunlight from the eyes.

A stress ball is a malleable toy, usually not more than 7cm in diameter. It is squeezed in the hand and manipulated by the fingers, ostensibly to either help relieve stress and muscle tension or to exercise the muscles of the hand.

There are many types of stress balls. Many are a closed-cell polyurethane foam rubber. This type of stress ball is made by injecting the liquid components of the foam into a mold. The resulting chemical reaction creates carbon dioxide bubbles as a byproduct, which in turn creates the foam.^[1]

Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, or phase. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.

A pen (Latin pinna, feather) is a writing instrument used to apply ink to a surface, usually paper. There are several different types, including ballpoint, rollerball, fountain, felt-tip. Historically, reed pens, quill pens, and dip pens were used
