Lightbeam (called Collusion in its experimental version) was an add-on for Firefox that displays third party tracking cookies placed on the user's computer while visiting various websites. It displays a graph of the interactions and connections of sites visited and the tracking sites to which they provide information.
A few steps aside and the narrow beam becomes invisible. Twibright Ronja with 130-millimetre (5.1 in) diameter lenses, operating on a 1,205-metre (1,318 yd) link using visible red light, max. range 1,300 metres (1,400 yd), with HPWT-BD00-E4000 transmit LED. Installed on a rooftop, with its user, in Czech Republic.
A diffractive beam splitter can generate either a 1-dimensional beam array (1xN) or a 2-dimensional beam matrix (MxN), depending on the diffractive pattern on the element. The diffractive beam splitter is used with monochromatic light such as a laser beam, and is designed for a specific wavelength and angle of separation between output beams.
The slotted optical switch, sometimes known as opto switch or optical switch but not to be confused with the optical component, is a device comprising a photoemitter (e.g. LED) and a photodetector (e.g. photodiode) mounted in a single package so that the photoemitter normally illuminates the photodetector, but an opaque object can be inserted in a slot between them so as to break the beam.
A generator interlock kit (or a transfer switch), eliminates the need for extension cords to power appliances. [2]Like a transfer switch, an interlock kit lets the generator energize the panel and all of its circuits (up to the load capacity of the generator); not just corded appliances.
Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named Firefox Quantum. A Mozilla executive stated that Quantum was the "biggest update" to the browser since version 1.0. [44] [45] [46] Unresponsive and crashing pages only affect other pages loaded within the same ...
Simplified single line diagram of a single-phase transfer switch to select either 'city' (utility) power or local generator power 3-phase Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a ...
In an OPA, the input is two light beams, of frequency ω p and ω s. The OPA will make the pump beam (ω p) weaker, and amplify the signal beam (ω s), and also create a new, so-called idler beam at the frequency ω i with ω p =ω s +ω i. In the OPA, the pump and idler photons usually travel collinearly through a nonlinear optical crystal.
