GE Appliances was originally a part of General Electric, a company which began marketing a full roster of heating and cooking products in 1907. [11] In January 2004, it became part of GE Consumer & Industrial when GE Consumer Products (founded in 1905) merged with GE Industrial Systems (founded in 1930) to form GE Consumer & Industrial.
GE retained a 62.5% share of the merged company. In 2019, GE announced plans to reduce its ownership in Baker Hughes from 50.4% to 38.4% losing majority control. [3] In October, 2019, GE sold a portion of its 62.5% stake in BHGE, reducing its ownership below 50%, and BHGE was rechristened as Baker Hughes Company (NYSE:BKR). [4]
In 1962, Robert Mazur (US Patent 3,628,137) and Dickey [1] developed a practical 2-probe system using a pair of weighted osmium needles. In 1970, Solid State Measurements was founded to manufacture spreading resistance profiling tools and in 1974, Solecon Labs was founded to provide spreading resistance profiling services.
Traditional techniques such as four-point probe (4PP), [13] secondary ion mass spectrometry (SIMS) and Hall effect measurements do not measure electrical depth profiles and are, by themselves, not adequate to characterize semiconductor layers with electrical properties that vary as a function of depth through the film (i.e.; surface activation ...
The GE Passport is a high bypass ratio turbofan. The engine is a twin-spool, axial-flow turbofan with a high bypass ratio of 5.6:1 and an overall pressure ratio of 45:1. The front fan is attached to the three-stage low-pressure compressor; the 23:1 pressure ratio 10-stage high-pressure compressor includes five blisk stages for weight reduction.
A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to ...
Because these probes generally acquire one point at a time and at high sample speeds, acquisition of long (continuous) surface profiles is possible. Scanning can take place in hostile environments, including very hot or cryogenic temperatures, or in radioactive chambers, while the detector is located at a distance, in a human-safe environment ...
As an ultrasonic testing (UT) method, EMAT has all the advantages of UT compared to other NDT methods. Just like piezoelectric UT probes, EMAT probes can be used in pulse-echo, pitch-catch, and through-transmission configurations. EMAT probes can also be assembled into phased array probes, delivering focusing and beam steering capabilities. [6]
