Ride-sharing is a transport model in which passengers order rides using an app and drivers use their own vehicles to deliver these orders. Companies such as Uber and Lyft act as intermediaries, charging a commission on each trip. These companies are now moving towards robotaxis – autonomous vehicles capable of transporting passengers without a human driver.

RG-6 cables by TRISET 302 – match the appropriate F connector.
TRISET 302 coaxial cables come in several popular versions, each with a slightly different structure due to the material of the cable's outer sheath. The outer sheath of the coaxial cable can be made of a synthetic PVC polymer (typical inner cables), a polyethylene PE coating (outer) or LSZH (Low Smoke Zero Halogen) plastic (cables with an increased fire resistance class –Dca, B2ca). Cables made with PVC technology are softer than PE or LSZH cables. When using hard sheathed cables, proper fitti...
Static color palette for thermal imaging cameras.
Thermal imaging cameras capture infrared radiation emitted by objects and convert it into an image in which the intensity of the radiation corresponds to specific temperature levels. The use of image coloring improves image clarity and makes it easier to analyze, as different temperatures are easier to identify with assigned colors....
Connection of additional reader via RS-485 to IP Villa Hikvision door station.
Hikvision Villa IP door stations of the DS-KV8xx3-WME1(C) series have an RS-485 input that can be used to connect an additional reader. The reader can be mounted on the exit side of the property in case the customer does not want to open the gate with a handle or local opening button. The DS-K1107AM G75369 can be used as an exit reader. Before connecting the reader, set the appropriate address on it, (e.g.:1) by moving the first DIP switch to the ON position. Then connect the reader via RS-485-...
Fiber optic categories and designations.
When studying fiber optic network design documentation, one will come across many designations for fiber optic cables and fibers. There are several popular styles of fiber naming. Some of them come directly from the designations proposed by standards and recommendations. Others are a confusion of these designations with abbreviated descriptions on the outer sheaths of cables....

Jedním z kritérií pro klasifikaci televizních systémů v hotelech je programová nabídka. Nejjednodušší systémy mohou poskytovat pouze volně dostupné pozemní televizní vysílání, zatímco pokročilejší řešení budou zahrnovat satelitní kanály, a to i některé prémiové (placená televize). Obsah požadovaný majitelem/investorem bude záviset na kategoriích potenciálních hotelových hostů (zahraniční a tematické kanály atd.).
