If you want to install only one GPS antenna to work with multiple GPS receivers (for structural or other reasons), you can connect up to 8 GPS receivers with a common GPS antenna by using the Active GPS Antenna Splitter 4449.  This is often used in performing device tests in laboratories or test stations. Active GPS antenna splitter 4449 has 8 outputs and a GPS signal amplifier for time server technologies. The power of this splitter is provided by two ways, either by devices connected to the time server or by an external power source.

If you choose to install only one GPS antenna (for structural or other reasons), you can set up two GPS receivers with a common GPS antenna using the 4443 Passive GPS Antenna Splitter. The time server system supplies the voltage of the Power Splitter 4443 through the GPS antenna cable of hopf GPS receivers. No external power supply is required to operate the program. If at least one of the connected GPS receivers provides the correct supply voltage through the antenna cable, and all connected components work in accordance with the main GPS L1 antenna signal, the GPS 4443 antenna splitter can be used together with another time server correctly.

The hopf signal converter 4800 series for 35 mm rail mounting (EN 50 022) is a low-cost solution for the distribution/conversion of a variety of electrical and optical signals. You can choose DC or AC power supply units for the signal converter4800. The converter can convert RS422, RS232 and RS485 signals to fiber, and vice versa, or to each other. This module is widely used to transmit time server information over long distances with the help of multimode fiber optic and IRIG-B protocol. After transmission by fiber, you can convert it to IRIG-B protocols.

Switch-Box - System 5000 was designed and developed to operate redundant clock systems in "hot standby function with automatic status-dependent signal switchover" mode of operation. The system 5000 is used when the most urgent demands are presented on the availability of a master clock system. The German Hopf system 5000 ensures that the output signal is given to the customer program with little error through the clock system. This system detects the error-dependent signal change between the primary system and its redundant system by monitoring the state of the respective clock system

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.
