TVNZ Teletext was a text-based information service provided by Television New Zealand (TVNZ). It offered viewers a range of information, such as news, weather updates, sports scores, and entertainment listings, all accessible through their television sets. The service used a teletext standard that allowed users to display text pages on their screens, which could be accessed using remote controls.

Teletext Ltd. is a media company that was originally known for providing teletext services in the UK. Established in the 1970s, it was one of the pioneers in delivering information to television viewers through a system that allowed access to news, sports updates, weather, and other types of information via a dedicated teletext signal. The service was widely used before the rise of the internet and digital TV. Teletext Ltd.

The Teletext character set is a specific collection of characters used in the teletext broadcasting system. Teletext is a telecommunication service that transmits textual information and graphics alongside television broadcasts using a variety of character sets and encoding methods. The character set typically used in teletext, notably in Europe and some other regions, follows the ISO 8859-1 or ISO 6937 standards, which include the Latin alphabet characters, digits, punctuation, and a selection of control codes for formatting and layout.

Televideo is a technology that was designed to provide teletext services, which are used to deliver text-based information over television broadcasts. Developed in the late 1970s and early 1980s, teletext systems allow viewers to access a variety of information, including news, weather, sports results, and program schedules, directly on their television screens.

Teletext was a technology used in the UK and many other countries to provide textual information and services alongside television broadcasts. The specific implementation in the UK was called "Ceefax," operated by the BBC, and there were also services from other broadcasters like ITV's "Oracle.

Teletext in the UK has a rich history, primarily associated with the development of digital broadcasting technologies. Below is a timeline highlighting key events in the evolution of teletext in the UK: ### 1970s - **1974**: The UK’s teletext system, known as Ceefax, was developed by the BBC as an experimental project. It was designed to provide information services to television viewers through a data transmission system.

AlphaCom is a communication platform developed by the company Alpha Networks, often used for intercom, access control, and emergency communication in various settings, including residential buildings, industrial facilities, and commercial establishments. It typically provides features like audio and video communication, integration with building management systems, and support for mobile applications.

Character Generator Protocol (CGP) is a network protocol that enables communication between a character generator device and other devices, such as video switchers or broadcast automation systems. It is mainly used in television broadcasting and video production environments to facilitate the dynamic insertion of text and graphics into video feeds. The protocol allows for the real-time control of text and graphic elements that may include things like lower thirds, sports scores, captions, and other on-screen graphics.

Linux.Wifatch is a type of malware that was discovered in late 2014. It specifically targets Internet of Things (IoT) devices, such as routers and networked cameras, particularly those that run on the Linux operating system. Wifatch is notable for being distinct from typical malware in that it does not primarily aim to steal information or cause damage.

The Polder tensor is a mathematical construct used in the context of electrodynamics, particularly in the study of magnetoelectric materials and electromagnetic interactions in various geometrical configurations. It describes the coupling between the electric and magnetic responses of a material, particularly in systems where both types of polarization are induced simultaneously.

Reverse Telnet is a technique that allows a device, typically a network device or embedded system, to establish a connection back to a host computer over a network, typically using the Telnet protocol. It reverses the traditional Telnet usage where a client connects to a server. In Reverse Telnet, the device acts as a client, connecting back out to a server that can then communicate with it.

Synchronet is a robust and flexible bulletin board system (BBS) software that allows users to create and manage a BBS on various operating systems, particularly Windows and Linux. Initially developed for DOS, Synchronet has evolved over the years to incorporate many modern features while maintaining its classic BBS functionality. Key features of Synchronet include: 1. **Multi-User Functionality**: Allows multiple users to connect simultaneously and interact with the BBS.

TN3270 Plus is a terminal emulation software specifically designed for connecting to IBM mainframe systems using the TN3270 protocol. TN3270, or Telnet 3270, is a protocol that allows users to access mainframe applications and systems that traditionally use IBM 3270 terminals. TN3270 Plus enables users to emulate the functionality of these older mainframe terminals on modern computers, providing a user-friendly interface to interact with mainframe applications.

A "nephelescope" is not a widely recognized term in science or technology. However, it seems to blend two concepts: "nephele," which is derived from the Greek word for cloud, and "scope," which generally refers to an instrument for viewing or observing. In speculative contexts, it could imply a device used for observing clouds or weather patterns, possibly in a metaphorical way, like forecasting or visualizing atmospheric phenomena.

Noise temperature is a concept used in radio frequency (RF) engineering and antenna theory to quantify the amount of thermal noise generated by an antenna or its surrounding environment. Specifically, it is an effective temperature that characterizes the noise power generated by the random motion of electrons in the antenna and the surrounding materials, which can affect signal reception and transmission.

Optothermal stability refers to the ability of a material or system to maintain its structural, optical, and thermal properties under varying temperature and light conditions. This concept is particularly important in fields such as materials science, optics, nanotechnology, and photonics, where the performance of materials and devices can be significantly affected by temperature fluctuations and exposure to light.

A **pyrometric cone** is a device used to measure the temperature of materials during the ceramic firing process. It consists of a tapered, triangular shape made from a specific mixture of clay and other materials that are formulated to melt at precise temperatures. Pyrometric cones are typically used in ceramic and pottery kilns to indicate the heat work (the combined effect of temperature and time) that a piece of pottery or ceramic has experienced.

"Red Heat" is a 1988 action-comedy film directed by Walter Hill, starring Arnold Schwarzenegger and James Belushi. The film features Schwarzenegger as Ivan Danko, a tough Soviet police officer, and Belushi as Art Ridzik, a wisecracking Chicago detective. The plot revolves around the unlikely partnership between the two as they team up to take down a drug lord. The film is notable for blending action and humor while exploring the cultural differences between the two main characters.

The Ring and Ball apparatus is a device used to determine the softening point or the softening temperature of thermoplastic materials, such as resins, bitumens, and waxes. This is important for assessing the performance characteristics of these materials under heat. ### Components of the Apparatus: 1. **Ring**: A small metal ring, typically made of brass or another conductive metal, which holds the sample of the thermoplastic material.

Le Potier's vanishing theorem is a result in algebraic geometry concerning sheaf cohomology on certain types of varieties, specifically on smooth projective varieties. It is particularly concerned with the behavior of cohomology groups of coherent sheaves under the action of the derived category.
