DCF77 4417 / 4418 / 4420 / 4436 / 4437 antennas are all German hopf antennas with active directional capability and an electrical design. Ferrite antennas are used for long wave range frequencies to keep the antennas small. The oscillating circuit in the antenna, which is made of a wire ferrite rod and various capacitors, is set up on 77.5 kHz. DCF77 is a standard for transmitting time (hours, minutes and seconds) and date to clocks and timing devices, and it is transmitted to devices with high accuracy by radio (local transmitter).

It supports 2 NTP Ethernet interfaces, IRIG-B protocol, DCF77, cyclic pulses, PRP and PTP, etc. Multiple power sources and various hardware interfaces in this time server have turned it into a competitive, stable, durable and reliable product.

German Hopf Time Server GPS Amplifier 6849 is manufactured in an anti-HF housing with integral plate. So, it is easy to fix the device to the wall. The amplifier 6849 supplies the line amplifier voltage through the antenna cable by the BNC connector of the hopf GPS system. The amplifier is used when the length of the antenna cable is more than 100 meters, or when the received signal of antenna is very weak. Generally, the amplifier is used to increase the length of the Time Server antenna cable. The manufacturing technology of this amplifier is complex, and it has ideal technical features.

Indirect Lightning Protection DCF77 4441 / 4444 of Hopf Time Server: When using outdoor antennas, the antenna cables may encounter high interference voltage caused by lightning. This may destroy not only directly connected radio controlled clock systems but also other connected devices. An indirect lightning arrester should be connected between the outdoor antenna and the radio controlled clock to avoid high costs and subsequent damage. It is necessary to short circuit all the lines with excessive voltage, so that the overvoltage is reduced as quickly as possible. After the interference is over, the device must return back to its previous settings. Hopf indirect lightning protection is a combination of different components.

Activity detection is a crucial task in computer vision as it enables machines to understand human actions and behaviors. In this abstract, we focus on activity detection in ACIC (Advanced Composites Image Corporation). ACIC is a leading company in the field of advanced composites manufacturing, dealing with high-performance materials for aerospace and defense industries. Developing an accurate activity detection system in this domain can enhance safety, efficiency, and quality control.
