A lamp using a gooseneck. A gooseneck is a semi-rigid, flexible joining element made from a coiled metal hose. Similar to its natural counterpart, it can be bent in almost any direction and remain in that position. [1] Areas of application for goosenecks are movable brackets for lights, magnifying glasses, microphones and other devices. [2]
Two kinematic mirror mounts, with mirrors. A mirror mount is a device that holds a mirror.

Common implementations of goosenecks are ventilator piping or ducting for bathroom and kitchen exhaust fans, ship holds, landfill methane vent pipes, or any other piping implementation exposed to the weather where water ingress would ...
The Patient Operated Selector Mechanism (POSM or POSSUM) was developed in the early 1960s, and used a sip-and-puff control mechanism. Sip-and-puff or sip 'n' puff (SNP) is assistive technology used to send signals to a device using air pressure by "sipping" (inhaling) or "puffing" (exhaling) on a straw, tube or "wand."
A wheel clamp, also known as wheel boot, parking boot, or Denver boot, [1] [2] is a device that is designed to prevent motor vehicles from being moved. In its most common form, it consists of a clamp that surrounds a vehicle wheel, designed to prevent removal of both itself and the wheel. [3]
The wheelchair symbol is "international" and therefore not accompanied by Braille in any particular language. Specific uses of the ISA include: Marking a parking space reserved for vehicles used by people with disabilities/blue badge holders; Marking a vehicle used by a person with a disability, often for permission to use a space
