ST and Microsoft Collaborate to Accelerate the Development of Motion and Position Sensors
The cooperation between STMicroelectronics and Microsoft shows that STMicroelectronics has the ability to integrate multiple sensors and processing functions and special software within a single module to provide users with total sensor solutions. STMicroelectronics' award-winning iNEMO sensor module is now in production. The solution integrates 3-axis digital gyros, 3-axis digital accelerators and proximity sensors, pressure sensors and STM32 microcontrollers. The microcontroller is used to run STMicroelectronics' iNEMOEngine sensor fusion algorithm to control human-machine interface devices through the Intelligent Interface Controller (I2C) protocol.
Benedetto Vigna, vice president of STMicroelectronics and general manager of analog products, MEMS and sensor products, said: "Working with Microsoft enables our sensors to run iNEMOEngine software on the Windows 8 operating platform, running x86 and ARM processing on the new Windows operating system. On the device, STMicroelectronics' HID sensor solution has plug-and-play functionality. Through Microsoft's sensor-driven software stack and ST's sensor-controller firmware, device manufacturers do not need to develop drivers, and end users can obtain Windows 8 sensor applications. Features such as screen rotation or room positioning built into Windows 8 and power saving through the iTMMO module's built-in STM32 microcontroller.â€
During the development of the Windows 8 sensor ecosystem and user experience, STMicroelectronics was one of Microsoft’s major partners and provided direct advice and feedback for Microsoft’s future sensor specification and platform development.
In addition to HID sensor solutions, STMicroelectronics is also a provider of MEMS total solutions, and it also provides customer drivers for future Windows8. This sensor-driven solution is based on STMicroelectronics' mass-produced Windows 7 sensor-driven software. STMicroelectronics is one of the few vendors that have certified through Windows 7 Motion and Position Sensors, which in turn demonstrates ST’s commitment to supporting Microsoft’s solutions.
The optical module (optical module) is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving.
Simply put, the function of the optical module is to convert the electrical signal into an optical signal at the transmitting end, and after transmitting through the optical fiber, the receiving end converts the optical signal into an electrical signal.
The optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. Optical modules are classified according to the packaging form. Common ones include SFP, SFP+, SFF, Gigabit Ethernet Interface Converter (GBIC), etc.
The transmitting part is: the electrical signal with a certain code rate is processed by the internal drive chip and then drives the semiconductor laser (LD) or light-emitting diode (LED) to emit the modulated light signal of the corresponding rate. The internal optical power automatic control circuit makes The output optical signal power remains stable.
The receiving part is: the optical signal of a certain code rate is input into the module and then converted into an electric signal by the light detection diode, and the electric signal of the corresponding code rate is output after the preamplifier.
