In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the sender's side to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the digital domain, scrambling usually refers to operations carried out in the analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation.
The question mark? is a punctuation mark that indicates a question or interrogative clause or phrase in many languages.

In playing cards, a suit is one of the categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it, except on face cards. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. In a single deck, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers.
A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
The inverted question mark, ¿, and inverted exclamation mark, ¡, are punctuation marks used to begin interrogative and exclamatory sentences or clauses in Spanish and some languages which have cultural ties with Spain, such as Asturian and Waray languages. The initial marks are mirrored at the end of the sentence or clause by the 'ordinary' question mark, ?, or exclamation mark, !.
The interrobang, also known as the interabang‽, is an unconventional punctuation mark intended to combine the functions of the question mark and the exclamation mark. The glyph is a ligature of these two marks and was first proposed in 1962 by Martin K. Speckter.
The Shins is an American indie rock band formed in Albuquerque, New Mexico, in 1996. The band is the project of singer-songwriter James Mercer, who has served as the band's sole constant member throughout numerous line-up changes. The band's current line-up consists of Mercer, alongside Yuuki Matthews, Mark Watrous, Patti King (keyboards), and Jon Sortland (drums). They are based in Portland, Oregon.
A power inverter is a device that converts direct current to alternating current.
A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Power electronics is the application of electronics to the control and conversion of electric power.
In archaeology, a beaker is a small round ceramic or metal drinking vessel shaped to be held in the hands. It has no handle or spout.
The inverted bell is a metaphorical name for a geometric shape that resembles a bell upside-down.
In music theory, an inversion is a type of change to intervals, chords, voices, and melodies. In each of these cases, "inversion" has a distinct but related meaning. The concept of inversion also plays an important role in musical set theory.
A death knell is the ringing of a church bell to announce the death of a person. Historically, it was the second of three bells rung around death, the first being the passing bell to warn of impending death, and the last was the lych bell or corpse bell, which survives today as the funeral toll.
3D Aerobatics or 3D flying is a form of flying using flying aircraft to perform specific aerial maneuvers. They are usually performed when the aircraft had been intentionally placed in a stalled position.
In civil engineering, the invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. The invert is an important datum for determining the functioning or flowline of a piping system. For example, the invert of a street sewer connection could affect the feasibility of adding a toilet in the basement of a house.
Inverted breve or arch is a diacritical mark, shaped like the top half of a circle ( ̑ ), that is, like an upside-down breve (˘). It looks similar to the circumflex (ˆ), which has a sharp tip, while the inverted breve is rounded:.
