STMicroelectronics, a semiconductor industry leader in global electronics applications, recently introduced an automotive-grade 6-axis inertial sensor, the ASM330LHH, for advanced vehicle navigation and telematics applications. Ultra high resolution motion tracking.
The ASM330LHH can meet the needs of continuous and accurate vehicle positioning to support various types of automation services. In the case of satellite signal blocking, the ASM330LHH can use sensor data to accurately calculate the position information of the vehicle through advanced dead reckoning algorithms. In urban canyons, tunnels, covered roads, parking lots or dense forests, satellite signal loss occurs from time to time. Its advanced low-noise, temperature-stable design enables reliable telematics services such as networked electronic toll collection systems, remote diagnostics and electronic call assistance. In addition, its 6-axis precision inertial data can also meet the needs of advanced autonomous driving systems.
Magneti Marelli chose the ASM330LHH for its advanced telematics system as a raw device in a series of models that will be launched by the global automotive group in the future.
For the ASM330LHH and the MEMS sensors it contains, ST has mastered the entire manufacturing process from sensor design to wafer fabrication, packaging, testing, calibration and supply. This complete end-to-end control enables ST to create a high-performance sensor while ensuring a strong and responsive supply chain through rigorous end-of-line quality screening.
“ST is the largest supplier of MEMS sensors for automotive non-safety applications, such as navigation and telematics applications,†said Andrea Onetti, vice president of ST analog, MEMS and sensors. “Our latest generation automotive inertial sensor ASM330LHH can be Safer, smarter driving provides high-precision vehicle positioning."
ST expects to provide ASM330LHH engineering samples for evaluation in the third quarter of 2018, and mass production is expected to begin in the fourth quarter of this year. The budget for 1000 orders is priced at $5.00.
The electrolyte material inside the electrolytic capacitor, which has charge storage, is divided into positive and negative polarity, similar to the battery, and cannot be connected backwards.A metal substrate having an oxide film attached to a positive electrode and a negative electrode connected to an electrolyte (solid and non-solid) through a metal plate.
Nonpolar (dual polarity) electrolytic capacitor adopts double oxide film structure, similar to the two polar electrolytic capacitor after two connected to the cathode, the two electrodes of two metal plates respectively (both with oxide film), two groups of oxide film as the electrolyte in the middle.Polar electrolytic capacitors usually play the role of power filter, decoupling (like u), signal coupling, time constant setting and dc isolation in power circuit, medium frequency and low frequency circuit.Non-polar electrolytic capacitors are usually used in audio frequency divider circuit, television S correction circuit and starting circuit of single-phase motor.
