In 2000, Simplehuman was founded by Frank Yang, who immigrated to the United States from Taiwan in 1982 [2] [3] and later started the company with the idea of making a better trash can. [1] [4] He showed his design and received his first orders at the International Home and Housewares Show from retailers such as The Container Store and Bed Bath ...
A sensing floor is a floor with embedded sensors.Depending on their construction, these floors are either monobloc (e.g. structures made of a single frame, carpets). [1] [2] [3] or modular (e.g. tiled floors, floors made of stripes of sensors).
A whisk broom or spotlight sensor, also known as an across-track scanner, is a technology for obtaining satellite images with optical cameras. [1] It is used for passive remote sensing from space. In a whisk broom sensor, a mirror scans across the satellite ’s path ( ground track ), reflecting light into a single detector which collects data ...
An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output. An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively between circuits ...

A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
A passive infrared detector mounted on circuit board (right), along with photoresistive detector for visible light (left). This is the type most commonly encountered in household motion sensing devices and is designed to turn on a light only when motion is detected and when the surrounding environment is sufficiently dark.
A PIR motion detector used to control an outdoor, automatic light. A camera trap with PIR motion detector. An indoor light switch equipped with PIR-based occupancy sensor [1] A PIR-based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically activated lighting ...
