Biodegradable integrated circuits. Researchers at the University of Wisconsin-Madison have developed an innovative method for the construction of completely biodegradable integrated circuits. They noted that the layer constituting the substrate for active electronic circuits is in fact 99% of the whole electronic chip and can be replaced by a different material. They used an organic substance called cellulose nanofiber (CNF), made from wood. This material, simply a kind of paper, is strong, flexible, and transparent. The cellulose nanofibers are covered with a special resin that ensures the required smoothness of the surface and forms a protective barrier against moisture.

The use of semiconductors was greatly reduced due to special technological process. Then they were simply adhered to the CNF substrate. Such integrated circuits can be used in a wide temperature range and can operate in the gigahertz band, e.g. as RF GaAs devices in cellular phones.
The life cycle of the biobased and biodegradable CNF substrate:
nature - production - biodegradation - nature
The most important advantage of the new material is its biodegradable characteristic - the lack of a negative impact on the environment. The devices could be thrown away in the forest, where they would be degraded via fungal biodegradation and converted into a fertilizer. And the cost of production of integrated circuits on the cellulose nanofibers is similar to traditional methods. This is particularly important due to the quickly rising amount of so-called e-waste. These electronic products are extremely harmful to the environment. It is estimated that the most commonly used electronic devices such as cell phones are on average replaced by new models every 18 months, laptops and computers after about 36 months. So far, the majority of them is not properly recycled and pollutes the environment.

It's been 25 years! The history of DIPOL company dates back to 1990, when a group of enthusiasts began to manufacture antennas for reception of analog TV and FM radio. As in the case of many "garage" companies of that time, the first "production hall" was the basement of one of the company founders. At the beginning, the products were mainly sold in marketplaces in Krakow and Warsaw.

TRISET cables for modern SMATV systems. Signal distribution networks in SMATV systems use multiple coaxial cables arranged in parallel. The lengths of the cable bundles in buildings can reach even 100 meters. It is the reason why the coaxial cables should be characterized by at least the A class of screening efficiency. Effective shielding reduces the crosstalk among the cables, i.e. the unwanted signals coming from adjacent cables. The interference could lead to image distortions or even image "freezing", similarly to situations with weak or low quality signals. Another feature of a good coaxial cable is low insertion loss. The risk of installing low quality cables is very high, including the necessity of replacing the entire wiring shortly after the installation. To eliminate such a risk, we supply high quality TRISET coaxial cables.
The members of the TRISET family:
  • TRISET PROFI E1010 Class A++ cable has been designed for broadband networks. Due to its construction (double foil, tinned copper braid with a high degree of coverage), it ensures very high screening efficiency in the return channel band, defined in the 5-30 MHz range frequency range as transfer impedance, <0.9 mΩ/m. This feature is especially important in HFC/CATV networks providing access to the Internet.
In the lowest frequency range used in antenna systems (5-30 MHz), the measure of screening efficiency is transfer impedance expressed in [mΩ/m], so given per unit length of the cable. This parameter is essential for cables used in CATV systems with return path, using this frequency range for Internet services.
  • TRISET-113 E1015 Class A cable is dedicated for individual and community antenna installations, SMATV systems etc., for distribution of DVB-T, FM/DAB, DVB-S/S2 broadcasts (also in multiswitch systems) inside buildings. An optimum flexibility of the jacket allows for easy installation of the cable in cable ducts and installation boxes.
  • TRISET-113 PE E1017 Class A cable can be used in individual and community antenna installations, SMATV systems etc., for distribution of DVB-T, FM/DAB, DVB-S/S2 broadcasts (also in multiswitch systems). Thanks to PE coating, the gel-filled cable can be installed outdoors, e.g. for connecting antennas placed on roofs etc.

  • TRISET-113 HF E1019_500 Class A cable is dedicated for use in community and cable TV installations. The cable is made in HF (halogen free) technology so it is also suitable for building installations in schools and hospitals. In the case of fire, the cable is flame retardant and emits little smoke, the emitted gases are not corrosive.
New LTE antenna. The ATK-LOG ALP LTE MIMO A7055_10 antenna has been designed for use in GSM/DCS/UMTS/HSDPA/LTE systems working in 800-3000 MHz range. It effectively solves the problems of inadequate signal level which often occurs in the case of modems/devices with built-in antennas. The 10-meter cable is terminated with FME-female (or SMA-f - the A7054_10 version) connector that can be directly connected to the cellular device.

The parameters of the antenna have been tested by the staff of the AGH University of Science and Technology in Krakow.
Gain vs. frequency characteristics of the ATK-LOG ALP LTE MIMO 2x2 A7054_10, A7055_10 antennas
The antenna is made from the highest quality materials. The housing of the ATK-LOG ALP antenna has minimal impact on the gain of the device (see the chart above). The antenna is produced in strong technological discipline that ensures excellent performance and high repeatability. With small size, the device guarantees 8-9 dBi gain in the whole operating band.
Connecting optical fibers at the entrance to the building - an example of implementation. Under the current rules, cables for indoor applications must meet stringent requirements for flammability. The cable jacket has to be non-flammable, halogen free (LSOH) and should meet the safety requirements in compliance with IEC 60332-1 and IEC 60332-3 standards.
In the case of implementing optical links between buildings, it is necessary to change the outdoor cable to a suitable indoor version, not more than 15 meters from the inlet to the building. Depending on the needs and practical solutions, this change can be made in a small installation box or in a larger distribution frame. Regardless of the type of the solution, the necessary task is to splice the required or all fibers of the both cables (outdoor and indoor).
The pictures above show an example implementation of the transition from outdoor 8-fiber optical cable Ultimode OMT-108SM L79108 to indoor 4-fiber cable Ultimode IDC-4 SM L7504. The connections are protected by the Ultimode TB-04B L5404 box.
Fusion splicing of a fiber from the outdoor 8-fiber Ultimode OMT-108SM L79108 cable and a fiber from the indoor 4-fiber Ultimode IDC-4 SM L7504 cable. Please note that the holders have different colors: red for the fiber in 900 µm buffer and black for the fiber in 250 µm buffer. The fibers of the cables have been joined with the use of EasySplicer L5810 fusion splicer.
The both cables are composed of single-mode G.652D fibers. They have been joined with the use EasySplicer L5810 fusion splicer. Due to the different buffers of the fibers, there have been used two types of the holders, red for the fibers in 900 µm tight buffer from the indoor cable and black for the fibers in 250 µm buffer from the outdoor cable. The splices have been protected with 45 mm heat-shrinkable tubes L5554. In the case of the oven built into the L5810 splicer, the shrinking time is only 40 seconds.

Remote control of electrical appliances via OneLinkPLC. OneLinkPLC G7184 is an autonomous pair of switches used for control of two different electrical outlets without the need for an additional hub, control panel, or cable. The communication between the switches takes place directly via the 230 VAC power network. Each device has 5 wires for the connection to the AC power network and the local control switch.
Wire colors and functions:
  • blue (N mark on the PCB) - for connection with the neutral wire of the 230 VAC power network,
  • brown (L mark on the PCB) - for connection with the live wire of the 230 VAC power network,
  • red (IN (L/N) mark on the PCB) - for connection to local switch (between live wire),
  • black (NO mark on the PCB) - each of the contacts of the built-in relay.

An example of the control of electrical outlet and lamp using the pair of autonomous OneLinkPLC devices. The S1 switch connected to the "first" device controls the lamp connected to the "second" device, and the S2 switch connected to the "second" device controls the power outlet connected with the "first" device. The distance between the devices can be up to 1 km.
The output of the "second" OneLinkPLC device automatically adopts the state of the "first" device and vice versa. If the IN (L/N) input of one device is connected by the local switch to the AC line, the contacts of the relay of the second device will be closed, providing power to any electrical appliance. The devices operate in monostable mode - the relay contacts of them will be closed as long as the control input of any of them is connected by the local switch to the line (live wire). To enable communication when the devices are connected to different phases, one should employ additional device - PLC-Coupler-D2M.
OpenLinkPLC system is a perfect solution for remote switching on/off of electrical devices in every situation where it is difficult or not economical to use additional cables and wireless means do not guarantee the required reliability (obstacles, interferences).
An example of the application of the OpenLinkPLC system can be switching on/off some electrical appliances in a utility/farm building powered by AC line from the main/residential building over a distance, say, 200 meters. So far, the owner had to go to and fro every time he wanted to switch the power on or off. After installing the OneLinkPLC G7184 pair(s), he can do it remotely.
Video monitoring system in a park. PGnet company has installed IP CCTV system in the park in Horyniec Zdroj, Poland. The park has undergone a major revitalization - including a new pump room, amphitheater, fountains in the entrance and spa squares, and a skate park. To prevent vandalism and increase the overall security of the area, the investor decided to install a monitoring system.

Splitting DVB-C signal. Digital cable subscribers are often faced with the problem of bringing the signal to the second room. In the best case (when the signal is not encrypted), it is enough to use a splitter and an additional DVB-C set-top box (unless the second TV has DVB-C tuner). However, in most cases the signal is encrypted and it is necessary to pay for second subscription or at least for multi-room service... >>>more
