Scalable autonomous trucking system.

Aurora Innovation, known for designing autonomous vehicles, announced the completion of its Aurora Driver project, which involved the development of hardware used in tractor-trailers with SAE Level 4 automation (in this category, vehicles are capable of handling steering, braking, acceleration functions, as well as monitoring the entire environment and the movement of other vehicles in different environments, conditions and speeds). In this mode, the vehicle is able to drive autonomously from its starting point to its destination, subject to favorable road and weather conditions. In case of unusual situations, the system can be deactivated, prompting the user to take control of the vehicle. The technology developed will be used in a new line of unmanned tractor-trailers planned for production in cooperation with German company Continental starting in 2027.
Continental and Aurora have designed the world's first scalable autonomous trucking system.
Aurora has confirmed a plan to deploy a small fleet of fully autonomous trucks by the end of 2024. Upon completion of the project, the company aims to produce "thousands" of such vehicles within three years. The company was founded in 2017 by individuals with experience at Uber, Tesla and Waymo. By the end of the current year, the company plans to deploy 20 fully autonomous trucks, while in 2025 the number will increase to 100 units.
In April 2023, Aurora announced a joint project with Continental, indicating that the partnership will help expand production plans. The company has also entered into agreements to supply autopilot systems for Volvo trucks. The developers of the new system expect that its conservative approach to commercialization will make its products more practical than competing solutions.
The year 2024 will see the testing of prototypes at a plant located in New Braunfels, Texas. Continental will engage in "industrialization and validation" of Aurora's technology, after which it will begin series production at its factories. An additional backup system will enable manual control of the vehicle in the event of sensor and other equipment failures. The two companies will also prepare a "service package" for customers purchasing autonomous trucks.

Full access to Sunell's DVR via the Internet without port forwarding.

P2P cloud typically allows partial access to devices from the network. Using an app on a phone or computer, it is possible to get encrypted live view, play archive recordings, handle alarm notifications and basic device configuration.
For Sunell NVRs, in addition to standard P2P access, the Web NAT function can be activated, which allows full access to the device via a web browser. With this function, it is possible to configure all DVR parameters from a remote location.
This function is crucial for both the user, who easily gains full access, and the installer. The installer can remotely adjust parameters, add new cameras, and easily perform all necessary configurations. After enabling Web NAT, go to https://www.51cloudtech.com, where you enter the device's serial number. The NVR's browser interface will then appear, allowing you to log in and have full access as if the device were on the local network.
Such functionality will be appreciated primarily by installers, who, with the appropriate login credentials, will be able to verify the configuration of an NVR in an easy, fast and, above all, remote manner.

Fiber optic cable termination.

Fiber optic cables containing 4 or 8 fibers are the most common solution used for LAN connections in small businesses and industrial facilities. The termination point can be the popular ULTIMODE TB-04H L5304 subscriber box.

The ULTIMODE subscriber box has been designed for quick and easy installation of optical fibers. The box has space for the spare cable and four splice protectors. The outer cover is mounted by means of snaps and can be completely removed from the box.
Practical application of the L5304 box. In theory, the box is designed for mounting 4 SC simplex adapters and terminating 4 optical fibres. In practice however it is possible to fit up to 8 splices and use LC duplex adapters.

Hotel system – distribution of DVB-T2 and DVB-S/S2 signals in fiber optic cable.

An owner of a large hotel complex ordered the installation of terrestrial TV providing signals in the new DVB-T2 standard and DVB-S/S2 satellite signals. The system was to cover 5 sites and distribute a signal in the new DVB-T2 standard from a local transmitter and 20 FTA satellite programs in the form of digital DVB-T signal. For this purpose, a solution on TERRA brand equipment was chosen.

Diagram of the optical and copper system for 5 hotel facilities with DVB-T2 signal distribution (4 digital terrestrial TV multiplexes and 8 multiplexes from the tdx-481 R81621 transmodulator). Part of the source signal was allocated to the local subnet (the building with the service room). Single-mode optical fibers were connected to the remaining buildings.
To ensure the distribution of terrestrial TV signals of the best possible quality and to equalize the signal levels at the input of the system, the contractor has decided to use programmable multi-band amplifier PROFINO Revolution 6711 R89062. Reception and distribution of satellite programs is possible with the use of tdx-481 R81621 transmodulator. The configuration of the panels shown in the diagram allows to receive 16 satellite programs in Full HD quality from 8 transponders.
The DVB-T/T2 signal prepared for distribution is transmitted to other buildings via single-mode optical fiber. The mo418 4D31 R82522 optical transmitter with a laser power of 6 dBm was used to for that purpose. Moreover, the so414 R82527 optical splitter is mounted on the same DIN R82538 rail to divide the signal into four optical paths. The transmitter is powered by the DR-60-12 12V/4.5A R82532 power supply. The inverse conversion of the signal from the optical medium to copper wire is performed in hotel buildings by TERRA OD-005P R81760 optical nodes. The maximum signal level at the output of the node is 107 dBµV which allows the TV signal to be distributed to several dozen R62120 sockets without the need of additional amplifiers. In such a configuration of optical fiber devices, the DVB-T/T2 signal can be transmitted to a distance of up to 12 km.

HDMI and USB signal transmission in optical fiber.

Whenever the DVR viewing and control is to be carried out from a remote room (e.g. surveillance center), there is a need to transmit HDMI and USB signals. If the cable distance does not exceed 100 m the H3613 converters can be used and connected with a standard twisted-pair cable cat. 5e.
Where devices up to 200 meters away need to be connected, an intermediate active device such as switch N29915 should be used. However, already at such distances it is better to use media converters and fiber optic cable. The maximum length of the fiber optic cable depends on the media converters used and can be up to 40 km.

Worth reading

Sunell NVRs - disable notifications via alarm input. If the building has other systems besides the surveillance system, e.g. intelligent building system, access control system, or alarm system, it is worth considering the implementation of the NVR disarming function. Activating this function results in disabling notifications generated by alarm events, such as motion detection or crossing a virtual line. The events are normally recorded in the system and a record is kept, but alarm actions can be deactivated, such as o sending an email or sending notifications to the client application...>>>more
