OpenWorks showed off how the system works in a video (above) posted on Thursday.

OpenWorks Engineering is the company behind the device and is marketing the device to protect sensitive events and buildings.

Video: YouTube, OpenWorks "SkyWall gives you a physical barrier in the sky," reads the company's description of the device.

SkyWall, from U.K.-based OpenWorks Engineering, uses a shoulder-mounted weapon that fires a projectile with a net to capture drones.
|
|
In March OpenWorks Engineering unveiled its SkyWall prototype, which shoots out a net to capture the drone, and then safely grounds it using a parachute.
|
|
Looking ahead to the near future, OpenWorks Engineering is also working on a two-operator, tripod mounted SkyWall200, and a semi-autonomous SkyWall300 "permanent installation" cannon turret.

The latest advance from British firm OpenWorks Engineering takes the idea of netted capture further by offering a personal device that can physically capture a quadcopter and control its descent to the ground.

There's Battelle's DroneDefender, which promised to use radio control frequency disruption to jam a drone and bring it to the ground, as well as OpenWorks Engineering's SkyWall that captures drones in a net.

Video: YouTube, OpenWorks In terms of accuracy, the SkyWall, which is essentially a compressed air launcher in gun form, uses a laser-equipped SmartScope to acquire the target and shoot a smart projectile at the drone.

UK-based OpenWorks Engineering is offering the device — which looks like a gun from a flashforward scene in Terminator 2 — as a means to neutralize drones that spy on celebrities, compromise the security of government officials and are used to transport illegal contraband.

During the Middle Ages there was tin working at a St Agnes Head tin works site with an extractive pit for openworks and lode back workings.Monument No. 1152214 - Medieval tin working site. English Heritage National Monuments. Retrieved 20 September 2012.

"Beamworks" was the name given by the tinners to workings where the lode was followed by digging down from the surface, and the massive gullies that resulted remain prominent features of the moor today. Several of these gullies retain names that include the word beam: Gibby Beam, Willabeam and Scudley Beam, for example. They are also known as "openworks" or "gerts".Newman 1998, p.22.

The US armed forces have no defense against low-level UAV attack, but the Joint Integrated Air and Missile Defense Organization is working to repurpose existing systems. Two German companies are developing 40-kW lasers to damage UAVs. Other systems still include the OpenWorks Engineering Skywall and the Battelle DroneDefender.anti- UAV/ In late 2017, Russia established a ground-based unit to combat UAVs by jamming their controlling signals.

The large site was extensively surveyed by English Heritage in 1999, and details are held in the English Heritage Archive.Newman 1999, p.106 In common with most Dartmoor valleys, the entire valley floor of the upper River Plym and its tributaries are disturbed by the remains of streamworks. There are also a number of openworks that follow the lodes, and signs of leats and reservoirs and hundreds of prospecting pits.

The large gothic openworks are replaced by regular windows alternated with trompe l'oeil windows. Cardinal Dominique de La Rochefoucauld continued the renovation of the Salle des États by commissioning Hubert Robert four large mural paintings. Pierre-Louis Helin was required to make modifications to the Salle Synodale (Synodal Hall). During the Revolution, the palace served as a wheat storage and residence for the armed forces before housing the city's administration.

Openworks near the Warren House Inn. Looking down one gully towards a group of them in the middle distance, and more on the left side of the ridge beyond. By the 15th century, the sources of stream tin were becoming scarce and since the demand for tin was as strong as ever, the direct working of lodes was considered viable despite the greater effort needed in both extraction and refining.Newman 1998, p.20-21.

The issue that mine managers had to decide was whether it was worth removing the extra overburden to form a gulley in order to be able to mine deeper into the lode. In a similar fashion to streamworking, much use was made of water for the removal of the overburden and gangue. When digging large gullies the overburden, which consisted at least partly of decomposed granite ("growan"), was loosened with picks, and then water was used to wash away the unwanted material instead of manhandling it. Means of collecting, diverting and storing water were always associated with openworks.

A now archaic description of the early 20th-century economy is provided by the Encyclopædia Britannica Eleventh Edition: > Tarare is the centre of a region engaged in the production of muslins, > tarletans, embroidery and silk-plush, and in printing, bleaching and other > subsidiary processes. Till 1756, when the manufacture of muslins was > introduced from Switzerland, the town lay unknown among the Beaujolais > mountains. The manufacture of Swiss cotton yarns and crochet embroideries > was introduced at the end of the 18th century; at the beginning of the 19th > figured stuffs, openworks and zephyrs were first produced. The manufacture > of silk-plush for hats and machine-made velvets was set up towards the end > of the 19th century.

Compendium of Chinese Amulets Part 1: Openworks 29p loose, 1995. Unlike most other types of Chinese numismatic charms which usually tend to have square center holes if they’re holed, open- work charms tend to almost exclusively have round center holes though open- work charms with square center holes are known to exist and certain thematic open-work charms that feature human-made constructions mostly told to have square holes. Another distinctive feature of open-work charms is that they’re almost purely based on illustrative imagery and only a small minority of them contain legends written in Hanzi characters. While most other forms of Chinese numismatic charms are made from brass open-work charms are predominantly made from bronze.

Chinese charms with "barbarian" musicians, dancers, and acrobats (Traditional Chinese: 胡人樂舞雜伎錢; Simplified Chinese: 胡人乐舞杂伎钱; Pinyin: hú rén yuè wǔ zá jì qián) appeared during either the Khitan Liao or the Chinese Song dynasty. These charms generally depict four individuals of which one is doing an acrobatic stunt (such as a handstand) while the others are playing various musical instruments: a four-string instrument which might possibly be a ruan, a flute, and a wooden fish. Although most numismatic catalogs refer to these charms as depicting "barbarians" or huren (胡人, literally "bearded people") the characters depicted on these charms have no beards. The reverse side of these charms depict four children or babies playing and enjoying themselves, which is a common feature for Liao dynasty charms; above these babies is a person resembling a baby that appears to ride on something.Lu Zhenhai - Zhongguo gudai yasheng qianpu (Catalog of Chinese Charms) About 1800+ pieces by chapter: 1) Coin inscrip, 2) Good luck inscrip, 3) Zodiac, 4) Buddhist, 5) Daoist, 6) Horse, 7) Mythical (folklore) figures, 8) Openworks, 9) Odd shapes, 10) Misc.
