Self-healing batteries in electric cars.
Israeli startup StoreDot has announced that it is working on a system to automatically repair cells in batteries used in electric vehicles. The company has patented a proprietary process for regenerating cells. The details of how the system will work are not known, but according to the manufacturer, detection of damaged cells and regeneration will be automatic even if the vehicle is in use. The whole system is composed of a specially programmed battery management system (BMS), which checks the condition of individual cells and manages the systems responsible for their repair. A defective cell, e.g. one that overheats or has a lower capacity, can be regenerated.
Self-healing cells will extend the life of electric vehicle batteries and have a positive impact on their overall performance over time.
The entire process will run “in the background”, without having to stop. This will contribute to the longevity of the cells, the price of which is a significant part of the cost of the vehicle. Addressing the problem of battery degradation could be key to the growth of the electric vehicle market.
StoreDot's ultrafast-charging (XFC) battery cells have a cylindrical form factor and are expected to be available as early as 2024.
Another “electrical” problem is the long battery charging process. However, it looks like StorDot has made the right progress in this area as well, as it recently announced to be the first in the world to begin mass production of XFC (Extreme Fast Charge) cells. These are lithium-silicon cells with extremely short charging time – a battery can be charged in 10 minutes from 0 to 80%, and they are distinct for high energy density of 300 Wh/kg. With charging being that fast the lifetime is limited to 700 cycles, and perhaps the regeneration process mentioned above will allow this number to be significantly increased. The cells are already being tested by battery and electric vehicle manufacturers.
Family of Signal TV brackets.
The choice of a bracket for hanging a TV set on the wall comes down to three main features: load capacity, size and mounting standard. The most important criterion is the load capacity of the wall bracket, since it directly affects the safety of the receiver and the people staying near it.Each of the brackets listed in the table below can be adjusted horizontally. However due to the construction and design solutions used this adjustment may not be permanent. The TV will tilt to the left or right when the setting is adjusted. This is the case with cheaper solutions intended for fixed TV positioning. For those who want to adjust the TV position, e.g. depending on whether it is watched from behind the table or from the sofa, we recommend the LPA16-444AX E93164 and LPA49-466 E93170 brackets. The rigid structure, bushings and adjustable smoothness of movement will satisfy the most demanding customers.
Due to the fact that every year larger televisions (55" and more) are becoming more and more popular, special attention should be paid to the E93170 mount, capable of suspending up to a 90" TV weighing up to 65 kg.
Intercom system upgrade using DS-KIS703-P Hikvision kit.
DS-KIS703-P G73306 is a Hikvision video intercom 2-wire kit which is ideal for upgrading the existing door entry system or video intercom system without the need to replace the wiring. The kit includes a 7" monitor powered by 24 VDC from an external power supply. The monitor communicates with the door station and supplies it via the 2-wire bus. The door station has two relays to control the wicket and entrance gate. A great advantage of the door station is that it has a special 12 VDC output dedicated to powering the electric door strike. Therefore, the use of an additional power supply for this purpose is not necessary. The monitor is equipped with a Wi-Fi interface for wireless connection with a router in order to access the Internet or integrate with a monitoring system located in the local network. The system remote operation, such as call forwarding or remote control of relays, is possible using the cloud and smartphone application Hik-Connect. The kit is dedicated for one-subscriber premises and does not allow for further expansion using additional door stations or monitors.

Cyberpower UPS Selector.
Established in 1997 in the USA, CyberPower Systems Inc. designs and manufactures high quality uninterruptible power supplies (UPS . For easier product selection the UPS slector is available to find a backup power solution for the specific installation needs. With the selector, it is possible to specify the most commonly demanded parameters and filter the devices offered.
Filter parameters:
- Power Load - total active power rating of connected devices [W]
- Reserved Capacity– maximum UPS in relation to the rated active power [%]
- Runtime – device autonomy [min]
- Voltage – operating voltage range [V]
- Form Factor – enclosure type
- Topology – operating architecture:
- Standby - the connected devices are powered directly from the mains, and switched to UPS in the event of a power failure
- Line-interactive– the connected devices are powered by UPS, which controls the basic power specifications
- Online Double Conversion - the UPS performs full AC→DC→AC conversion, providing output voltage with the specified parameters.
HDBitT: HDMI over IP.
HDbitT (High-Definition Digital Bit Transmission Technology) is a protocol used for professional delivery/transmission of high quality video and audio over IP networks. It enables the transmission of audio/video at resolutions up to 4Kx2K @ 60Hz over the network cables, electrical wiring, fiber optic cable, coaxial cables, or wirelessly.HDbitT ensures all-in-one connectivity, enabling 4K Ultra HD audio and video distribution, as well as the transmission of RS232, IR, and USB control signals.
Key benefits of HDbiT:
- the distance over which a signal can be transmitted can far exceed 100m,
- HDbitT supports features such as: CEC, EDID and HDCP,
- support for multiple transmission media such as twisted pair, coaxial cable, fiber optics, electrical network, wireless network,
- possibility to secure transmission with the AES protocol,
- using the existing computer network for signal transmission,
- using efficient compression to save bandwidth in the network,
- plug and play devices,
- support for point-to-point and point-to-multipoint connections.
Devices supporting the HDbitT protocol:
- H3606 H3606 HDMI to IP Converter + remote control extender,
- H3606R HDMI to IP converter + remote control extender-receiver,
- H3608 HDMI to fiber optic converter + remote control extender,
- H3613 HDMI to IP converter with USB extender,

These splicers do not differ from each other in the way they work and in their use and configuration. Both models splice fibers in the same way, and they are configured using a smartphone with an appropriate app. What makes the two models different from each other is the appearance and the additional capabilities of the AI-9 model to verify the correctness of the completed fiber optic link.

The AI-9 L5875 is equipped with an optical power meter module and a visual fault locator. The former enables the measurement of the optical signal power level (provided the correct light source is used on the other side), while the latter allows for basic fiber and cabling diagnostics by introducing visible light into the fiber.
On the one hand, integrating both components into the splicer is a good solution as it avoids the need for three separate devices. On the other hand, those who perform measurements frequently, or want to be able to separate splicing work from measurements (performed in parallel by another person), should opt for the AI-8C model, and purchase the meter and visual fault locator separately.
