The 4.5mm MKR was designed in 1978 [1] by Interdynamic AB, a Swedish company, around the time of the rise of "micro-caliber" popularity. Firearms companies everywhere were trying to achieve a type of practical, light and cheap ammunition.
Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
Smart charging can be divided into two charging management systems, User-managed charging (UMC) and Supplier-managed charging (SMC). [3] For UMC, a Time-of-Use tariff is applied, and the customer decides the timing to charge based on the price and needs.
Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic ...
It was to use low-cost ammunition. The 4.5×26mm MKR round was claimed to be ballistically as effective at 300 meters as the 5.56×45mm NATO round. It was a bullpup design, which means that the magazine is located behind the trigger, and utilized the blowback system of operation. The bullpup design made the firearm smaller and lighter.
The alternating current signal produced by the flow of this charge is amplified and used as an analogue for the DC voltage applied to the capacitor. The DC input resistance of the electrometer is determined solely by the leakage resistance of the capacitor, and is typically extremely high, (although its AC input impedance is lower).
IEC 61107 or currently IEC 62056-21, was an international standard for a computer protocol to read utility meters. It is designed to operate over any media, including the Internet. A meter sends ASCII (in modes A..D) or HDLC (mode E) data to a nearby hand-held unit (HHU) using a serial port.
An ESR meter known not to have diode protection will give a reading of internal resistance for a rechargeable or non-rechargeable battery of any size down to the smallest button cells which gives an indication of the state of charge. To use it, measurements on fully charged and fully discharged batteries of the same type can be used to ...
