WRonald Hugh Barker FIEE was an Irish physicist and inventor of Barker code for digital synchronisation. He was a member of the Institution of Engineering and Technology (IET) for 70 years. Born in Dublin, Ireland, Barker had an erratic education but excelled in mathematics, becoming keen on electronics. He is best known for his ground-breaking work on synchronising digital communication systems and framing of received data, using digital codes. These digital codes are known as Barker code. The method was initially researched at SRDE Royal Signals Research Establishment, just after World War II for use in radar, rocket telemetry and digital speech. In 1952, Barker found 7 Barker sequences up to a length of 13 useful for correlation. These sequences are widely used in most data transmissions today. Examples of applications are radar, mobile phone technology, telemetry, digital speech, ultrasound imaging and testing, GPS and WiFi, etc.
WFujitsu Ltd. v. Netgear Inc., 620 F.3d 1321, was a patent infringement case centered on three patents claimed to be required for full compliance of the IEEE 802.11 (WiFi) standard and the WiFi Alliance Wireless Multimedia Extensions (WMM) Specification. US patents 4,975,952, 6,018,642, and 6,469,993 were owned by Philips Electronics, Fujitsu, and LG Electronics respectively, and placed in the Via Licensing pool. The Via Licensing pool claimed to hold all patents required for a complete WiFi/WMM implementation. Netgear did not enter an agreement with Via Licensing but produced a series of products that conform to the WiFi standard and WMM Specification. Philips Electronics, Fujitsu, and LG Electronics sued Netgear for patent infringement claiming a complete implementation of the WiFi standard implied violating patents held by Via Licensing pool. When tried in United States District Court for the Western District of Wisconsin, the court granted summary judgment of non-infringement by Netgear for all three patents thus plaintiffs appealed. The United States Court of Appeals for the Federal Circuit confirmed non-infringement for two of the three patent and found infringement of the third patent in four of Netgear's products.
WA home network or home area network (HAN) is a type of computer network that facilitates communication among devices within the close vicinity of a home. Devices capable of participating in this network, for example, smart devices such as network printers and handheld mobile computers, often gain enhanced emergent capabilities through their ability to interact. These additional capabilities can be used to increase the quality of life inside the home in a variety of ways, such as automation of repetitive tasks, increased personal productivity, enhanced home security, and easier access to entertainment.
