Rakon Limited is a technology company founded in 1967 that designs and manufactures frequency control products, primarily quartz crystals and temperature-compensated crystal oscillators ( TCXO ), [1] oven controlled crystal oscillators ( OCXO) and voltage controlled crystal oscillators ( VCXO ). [2] Its head office is in Auckland, New Zealand ...
A Central Equipment Identity Register (CEIR) is a database of mobile equipment identifiers ( IMEI – for networks of GSM standard, MEID – for networks of CDMA standard). Such an identifier is assigned to each SIM slot of the mobile device. Lists of IMEIs may be the: White – for devices that are allowed to register in the cellular network ...
In solid-state physics of semiconductors, carrier generation and carrier recombination are processes by which mobile charge carriers ( electrons and electron holes) are created and eliminated. Carrier generation and recombination processes are fundamental to the operation of many optoelectronic semiconductor devices, such as photodiodes, light ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens. It is widely used in optical engineering laboratory work to analyze and ...
The device numbers are enumerated in ANSI/IEEE Standard C37.2 "Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations". Many of these devices protect electrical systems and individual system components from damage when an unwanted event occurs such as an electrical fault.
In an alternating current (AC) electric power system, synchronization is the process of matching the frequency, phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are synchronized.
In a statement after the verdict, Trump alleged the trial was rigged, in addition to alleging that New York State Supreme Court Judge Juan Merchan, who presided over the case, was biased against him.
Nuclear physicist at the Idaho National Laboratory sets up an experiment using an electronic neutron generator. Neutron generators are neutron source devices which contain compact linear particle accelerators and that produce neutrons by fusing isotopes of hydrogen together. The fusion reactions take place in these devices by accelerating ...
