Ellis Island is a federally owned island in New York Harbor, situated within the U.S. states of New Jersey and New York, that was the busiest immigrant inspection and processing station in the United States. From 1892 to 1954, nearly 12 million immigrants arriving at the Port of New York and New Jersey were processed there under federal law. Today, it is part of the Statue of Liberty National Monument and is accessible to the public only by ferry. The north side of the island is the site of the main building, now a national museum of immigration. The south side of the island, including the Ellis Island Immigrant Hospital, is open to the public only through guided tours.
A knife is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin.
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention. In most countries, patent rights fall under private law and the patent holder must sue someone infringing the patent in order to enforce their rights.
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history.
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation. The fibers are then processed into various cotton goods such as calico, while any undamaged cotton is used largely for textiles like clothing. The separated seeds may be used to grow more cotton or to produce cottonseed oil.
A scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time. It offers a solution to the problem of navigation to a known or unknown location within a two-dimensional information space. It was also known as a handle in the very first GUIs. They are present in a wide range of electronic devices including computers, graphing calculators, mobile phones, and portable media players. The user interacts with the scrollbar elements using some method of direct action, the scrollbar translates that action into scrolling commands, and the user receives feedback through a visual updating of both the scrollbar elements and the scrolled content.
A button is a fastener that joins two pieces of fabric together by slipping through a loop or by sliding through a buttonhole.
Call waiting is a telephone service where a subscriber can accept a second incoming telephone call by placing an in-progress call on hold—and may also switch between calls. With some providers it can be combined with additional features such as conferencing, call forwarding, and caller ID. Call waiting is intended to alleviate the need to have more than one telephone line or number for voice communications.
A tape measure or measuring tape is a flexible ruler used to measure length or distance.
Prior art is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention. However, notable differences exist in how prior art is specifically defined under different national, regional, and international patent systems.
A switchblade is a pocketknife with a sliding or pivoting blade contained in the handle which is extended automatically by a spring when a button, lever, or switch on the handle or bolster is activated. Virtually all switchblades incorporate a locking blade, where the blade is locked against accidental closure when the blade is in the open position. It is unlocked by a mechanism that allows the blade to be folded and locked in the closed position.
In Canada and the United States, a railway post office, commonly abbreviated as RPO, was a railroad car that was normally operated in passenger service as a means to sort mail en route, in order to speed delivery. The RPO was staffed by highly trained Railway Mail Service postal clerks, and was off-limits to the passengers on the train.
Rug hooking is both an art and a craft where rugs are made by pulling loops of yarn or fabric through a stiff woven base such as burlap, linen, or rug warp. The loops are pulled through the backing material by using a crochet-type hook mounted in a handle for leverage. In contrast latch-hooking uses a hinged hook to form a knotted pile from short, pre-cut pieces of yarn.
The Port of New York and New Jersey is the port district of the New York-Newark metropolitan area, encompassing the region within approximately a 25-mile (40 km) radius of the Statue of Liberty National Monument.
This history of the telephone chronicles the development of the electrical telephone, and includes a brief overview of its predecessors. The first telephone patent was granted to Alexander Graham Bell in 1876.
Imperial Schrade Corp. was an American knife manufacturer of hunting knives, pocketknives, utility knives, and bayonets during the 20th and early 21st centuries. The consolidation of five forerunner companies, including its namesakes, the Imperial Knife Company, founded 1916, and the Schrade Cutlery Company, founded in 1904, Imperial Schrade manufactured its products in the United States and Ireland and sold through hardware stores, department stores, and on military bases. The original company's fortunes declined and in 2004 it entered into bankruptcy where all equipment and intellectual property was sold off to reimburse creditors. The name and intellectual property was bought by Taylor Brands and used for marketing purposes.

A telephone exchange, telephone switch, or central office is a telecommunications system used in the public switched telephone network (PSTN) or in large enterprises. It interconnects telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers.
A pin-back button or pinback button, pin button, button badge, or simply pin-back or badge, is a button or badge that can be temporarily fastened to the surface of a garment using a safety pin, or a pin formed from wire, a clutch or other mechanism. This fastening mechanism is anchored to the back side of a button-shaped metal disk, either flat or concave, which leaves an area on the front of the button to carry an image or printed message. The word is commonly associated with a campaign button used during a political campaign. The first design for a pin-back button in the United States was patented in 1896, and contemporary buttons have many of the same design features.
