Universal Powerline Bus
Universal Powerline Bus (UPB) is a proprietary software protocol developed bPowerline Control Systemsfor power-line communication between devices used for home automation. Household electrical wiring is used to send digital data between UPB devices via pulse-position modulation. Communication is peer to peer, with no central controller necessary. UPB addressing allows 250 devices per house and 250 houses per transformer, allowing over 62,500 total device addresses and can co-exist with other powerline carrier systems within the same home. , UPB enjoys one of the broadest range of device types when compared to most protocols and has support from some major manufacturers in the home automation space. Most notably, Leviton and theiOmniseries of home automation products, as well as the UPdevicesthey market. UPB is also supported by many major home automation software manufacturers. A few of which are listed below. Reliability UPB is a highly reliable protocol for home automation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Software
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors ...

Power-line Communication
Power-line communication (also known as power-line carrier or PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wires (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations. A number of difficult technical problems are common between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded environment. ...

Home Automation
Home automation or domotics is building automation for a home, called a smart home or smart house. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. When connected with the Internet, home devices are an important constituent of the Internet of Things ("IoT"). A home automation system typically connects controlled devices to a central smart home hub (sometimes called a " gateway"). The user interface for control of the system uses either wall-mounted terminals, tablet or desktop computers, a mobile phone application, or a Web interface that may also be accessible off-site through the Internet. While there are many competing vendors, there are increasing efforts towards open source systems. However, there are issues with the current state of home automation including a lack of standardized security measures and dep ...

Pulse-position Modulation
Pulse-position modulation (PPM) is a form of signal modulation in which ''M'' message bits are encoded by transmitting a single pulse in one of 2^M possible required time shifts. This is repeated every ''T'' seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical communications systems, which tend to have little or no multipath interference. History An ancient use of pulse-position modulation was the Greek hydraulic semaphore system invented by Aeneas Stymphalus around 350 B.C. that used the water clock principle to time signals. In this system, the draining of water acts as the timing device, and torches are used to signal the pulses. The system used identical water-filled containers whose drain could be turned on and off, and a float with a rod marked with various predetermined codes that represented military messages. The operators would place the containers on hills so they could be seen from each other at a distance. To send a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peer-to-peer
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model in which the consumption and supply of resources are divided. While P2P systems had previously been used in many application domains, the architecture was popularized by the file sharing system Napster, originally released in 1999. The concept has inspired new structures and philosophies in many areas of human interaction. In such social contexts, peer-to-peer as a meme refers to the egalitarian so ...

Leviton
Leviton Manufacturing Company, Inc. is an American manufacturer of electrical wiring equipment in North America. It produces electrical light sockets, receptacles and outlets, switches, dimmers and other lighting control systems, wire, power cables, power cords, wall and ceiling occupancy sensors, wall plates, datacom, and other electrical products. Leviton is perhaps most regarded for its Decora wall switch, introduced in 1973. Its flat, low profile form factor was a modern alternative to standard toggle switches in many homes and offices. Today "Decora" is often used as a generic term for decorative paddle switches regardless of manufacturer, but Decora is still a legally recognized trademark of Leviton. History The company was founded in 1906 by Isidor Leviton. He began by manufacturing brass mantle tips for the natural gas lighting infrastructure in New York City.

X10 (industry Standard)
X10 is a protocol for communication among electronic devices used for home automation (''domotics''). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio-based protocol transport is also defined. X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to allow remote control of home devices and appliances. It was the first general purpose domotic network technology and remains the most widely available. Although a number of higher-bandwidth alternatives exist, X10 remains popular in the home environment with millions of units in use worldwide, and inexpensive availability of new components. History In 1970, a group of engineers started a company in Glenrothes, Scotland called Pico Electronics. The company developed the first single chip calculator. When calculator integrated circuit prices started to fall, Pico refocused on commerci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
