Japan has legalized the "flying car.”

SkyDrive, a Japanese startup working on the development of the "flying car," announced that its vehicle has received a safety certificate. The certificate has been granted by Japan's Ministry of Infrastructure Transport and Tourism. The document certifies that the design and construction meet the necessary requirements for safety and environmental protection in terms of performance and durability.

The company first revealed its early prototype to the world in 2018. The latest version of the SkyDrive flying car is called SD-03. It uses eight propellers and reaches a top speed of 30 miles per hour (48 km/h) on a trip lasting up to 10 minutes. SkyDrive, intends to launch the SD-03 flying cab service in the Osaka Bay area of Japan as early as 2025.

It is worth mentioning that the SkyDrive model, unlike other nascent solutions, does not have an enclosed cabin, which would make it more suitable to be called a "flying motorcycle" and not, as all promotional and informational materials suggest, a "car". This certainly has a negative impact on safety, although it does not seem to have affected certification procedure with the authorities, who openly state that Japanese transport will have a new face by around 2025.

Redirecting calls from the Villa Hikvision IP door/gate station directly to a smartphone.

1-subscriber Villa Hikvision IP video gate/door stations have the ability to be added directly to the Hikvision cloud and to redirect calls to a smartphone with the Hik-Connect application installed without the need for an additional internal monitor (otherwise a monitor is always required). To use this functionality, connect the gate/door station to the Internet via wired or Wi-Fi link, create an account at www.hik-connect.com, install the Hik-Connect application, and add the device to the account. Once the system is configured, pressing the call button on the door station will set up a connection on the smartphone with the app installed. After answering the call, it will be possible to have a two-way conversation and open the electric door strike or the gate.

In the diagram above, the door station has been connected to the router via a PoE switch that also provides power supply. The electric door strike is controlled by an additional 12 VDC power supply, via the first built-in relay in the door station. The second relay is connected to control the entrance gate. The user can view the image from the door station at any time via the application, even if no-one is calling, and can trigger the relays if necessary.

Application of the digital HDMI-DVB-T modulator with an additional HDMI output.

The conversion of A/V signals into high-frequency RF signals, meaning the introduction of signals from all kinds of signal sources, such as computers, players or surveillance cameras, into a terrestrial TV system, is an operation that requires the use of a so-called modulator. Such device has one or multiple A/V inputs (RCA, HDMI, etc., depending on the type) and an RF output (commonly known as the "antenna output), and it allows you to watch the video and listen to the sound on the selected channel on all TVs connected to the system. For the receiver, the program added to the system is just another terrestrial television channel.

The MHD002P R86104 modulator is a multifunction device which provides input Full HD signal (1920x1080-30p), fed into the HDMI port, modulated in DVB-T COFDM standard. In addition to an HDMI input, the MHD002P R86104 is equipped with an HDMI output allowing to watch the video from the connected source.
