AEC-Q100 Qualified Automotive 3-Axis Accelerometer
ST Microelectronics’ Model AIS328DQ senses acceleration along three axes and converts motion and tilt data into high-resolution digital signal that is transmitted to MCU through SPI or I2C interface. Accurate across selectable full-scale ranges of ±2, ±4, and ±8g, the product is also resistant to shock and EMI. It operates in temperatures from -40 to +105°C, and can be used … [Read more...]
Profound Changes Affecting Worldwide Automotive Electronics Market
During the past 60 years, the automobile has evolved from a crude conveyance having no computers and simple point/condenser ignition to a sophisticated and capable traveling machine with twenty or thirty computers that control everything from ignition to heat and air conditioning, door window position and analog-style instrument panel. Manufacturers such as BMW, Porsche, GM, … [Read more...]
工具使得欧洲，中国标准更多
欧洲中国的标准化信息的平台（CESIP）是一个实用的信息工具，其目的是加强欧洲与中国之间的相互贸易和投资流动的标准和相关的技术法规。该平台是一个网站在中国和/或欧洲的中小型企业会发现在英国和中国的有关的适用和即将到来的标准被应用到他们的产品用于出口到中国和欧洲的信息。欧洲的中小型企业会发现不仅对国家，中国GB标准（自愿性和强制性的），但也对相关行业（部门）的标准，通常要困难得多想与中国做生意的外国公司获得的信息。 … [Read more...]
IEC Releases Corrigendum of CISPR 16 Part 1-1
The International Electrotechnical Commission has posted a corrigendum for the CISPR 16 Part 1 -1, which is the specification for radio disturbance and immunity measuring apparatus. The IEC draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning the measuring receiver with rms-average detector (patent no DE … [Read more...]
Holding Steady
As the economy gained momentum in late 2009 and early 2010, engineering organizations, like every other business sector, sensed promise that a strong, self-sustaining recovery was kicking in. However, as government spending to stimulate the economy trailed off and businesses concentrated on rebuilding their inventories, the growth rated started to slow – a pattern that … [Read more...]
