Sensor: MEMS integrated with IC tends to spread the high-end(A)

Automotive electronic control systems “normal operation” is inseparable from the sensor escort sony vgp bps9, through the sensor can be a variety, such as pressure, flow, position, height, distance, speed, speed, temperature and signal transmission to the power system, security system control unit, to achieve the purpose of driving a normal car. Is because of the need various signals, and thus a wide range of automotive sensors, currently on an ordinary family car is about to install only a few dozen to nearly one hundred sensors, while the number of sensors on the high-end cars can reach more than 200 only. Over the years, used to measure pressure, temperature and speed sensors measure has been the protagonist of automotive electronics, but the auto upgrade feature makes the sensor has gone beyond the sensor signals back to the control unit of such a level, the sensor’s “intelligent” already pretty VGP-AC19V13 clear.

Sensors and IC integration is the key

The intelligent sensors to improve the inevitable choice is IC and sensor integration, which has become the industry’s focus of attention. At present a lot of such products as clay Freescale, Infineon, NXP, and many other vendors charge for tire pressure sensor chip on the integrated sensor and IC. Other applications include pressure sensor chip, magnetic sensor chips are integrated.

Infineon sensing and control, said John McGowan, director, TPMS sensors requirement Sony VGP-BPS2A is rugged, long life and reasonable cost. Infineon developed a TPMS sensor is used for data processing and signal modulation CMOS ASIC with a piezoelectric pressure measuring element on a common lead framework. He also introduced, by processing and sensor integrated together, to ensure temperature compensation, self-tuning capabilities and failure mode detection accuracy. In terms of cost control, on a single chip can integrate multiple functions and features as well as the production area to focus on. And this intelligent sensor to allow more small CPU freed computing from the data so that it can be faster processing.

Billion in order to get Europe on a joint venture between VGP-BPS9 automotive sensor technology, Mori, director of Tektronix, said Pang Chuan, IC and sensor integration to reduce the size of the benefit is to reduce interference. He also said that an integrated approach in two ways: One is the SoC, high integration, but due to the sensor and IC processes are different, more difficult to achieve relatively large. The other is the SOP, is easier to achieve, mainly Sony VGP-BPS8 packaging clearance.

World’s Smallest 16-bit audio chip(A)

World’s Smallest 16-bit audio chip(A)

June 20, Tokyo – Oki Electric Industry Co., Ltd. (hereinafter referred to as OKI) began to supply Sony vgp bps2c the most suitable for recording and playback for portable devices the world’s smallest 16-bit audio CODEC chip, “ML2612 Series” sample.

The chip uses OKI’s W-CSP (Note 1) technology enables the world’s smallest 2.0mm × 2.5mm package size. Even small degrees of freedom for the design of small portable devices, you can also configure the microphone near the audio CODEC, and thus the VGP-BPS8 decline in sound quality caused by external noise control minimum. Moreover, the chip has built-in recording can be removed when the system noise, wind noise and other audio filters, as well as be able to compensate for the audio playback device when the inherent frequency response characteristics of small-scale equalizer.

OKI plans to begin in September 2007 with production quantities available in the chip.

In general, for devices with a microphone to the microphone of the weak perfect digital output signals, often must be installed near the microphone audio CODEC chip. A result, the design of the microphone around the freedom will be restricted. More recently, a film with a digital camera, can confirm VGP-BPS2A pronunciation learning machine with a microphone portable devices continue to emerge. Moreover, these devices smaller and thinner requirements are growing at an unprecedented rate, therefore, subject to limited installation space, audio CODEC chip and become the noise sources and other components installed on the same piece of circuit boards, high-density installation of Necessity is also becoming increasingly apparent.

OKI Group with VGP-BPS10

Silicon Solutions Company Masahiko Morioka, President said: “The response to these needs, OKI developed the equipment necessary to make a portable microphone amplifier, A / D converter (hereinafter referred to as ADC), D / A converter (hereinafter referred to as DAC), speaker amplifier to achieve ultra-small package, the audio CODEC. especially the W-CSP package can achieve in the past for small audio CODEC chip, 1 / 3 of the following package size, a significant improvement in the design of freedom around the microphone. but also through the built-in you can remove the recording of wind noise and the single-frequency sound system noise programmable filters, as well as be able to compensate for playback when the device is difficult to play a small domain-specific bass sound characteristics to achieve more natural playback of programmable equalizer, allowing improve all portable VGP-BPS9 B , VGP-BPS9 S devices recording, playback quality. “

As part of the development of interfaces, Summit Microelectronic and provides Windows GUI interface application software, engineers can by the development tools to simulate and set a variety of charging conditions, significant savings in development time.

Jilin Province plans to formulate regulations prohibiting the free disposal of waste batteries.

25, Jilin Province, the twenty-first meeting of the Tenth NPC Standing Committee held in Changchun. “The Jilin Construction VGP-BPS9, vgp-bps9/b Market Management Ordinance (Draft)” to address environmental problems of hazardous wastes, “hazardous waste pollution prevention and control of Jilin Province (Draft)” prohibited hazardous waste mixed with non-hazardous waste storage or emissions. Waste batteries, waste fluorescent tubes and waste minerals are harmful to human health, pollute the environment, a special hazardous wastes. Provincial People’s Congress deputy chairman of the Environmental and Resources Kou Cheng-fu suggested that in the “draft” clearly states: Prohibition of free disposal of waste batteries, waste fluorescent tubes and waste mineral oil, a clear management responsibility of the relevant departments.

In this case, the equipment manufacturers to improve every point on the canon battery are extremely great importance, not surprising. “Even if only 20% increase in energy efficiency, can allow mobile phones thinner or larger and brighter screen.” Samsung’s vice president for mobile business Mouz Bo Kaen, said: “It will bring more opportunities. ”

The problem is that the battery’s basic design has not changed, it really can not change. A component of energy releases electrons, a component to accept the energy, must also have a separate component to the previous two parts. The researchers can continue to search for the minimum weight and space to provide maximum chemical energy of new materials; over the past 10 years for consumer electronics products in the lithium-ion canon bp-208 battery is that people find the best option.

Most consumers are now aware that engineers were well aware of for many years a problem: the vgp-bps9/s battery can not keep up the development of other electronic devices. And, unfortunately, this situation not only can not be improved in the short term, there is likely to get worse before improving.

With the new mobile phones, music players, or notebook computers, most people would not put it down to it, wait for them to hold all day to play, provided that the battery Nengcheng put the situation. Thanks to ever-shrinking size of computer chips, consumer electronics industry for products to add more features, but this is far more than the vgp-bps9a battery industry can adapt to speed.

The famous Moore’s Law makes the computer chip capacity will double every two years or so. In the United States Menlo Park, California, Stanford Research Institute International (SRI International) chaired the study of physics, said Lawrence Dubois, battery capacity increase to almost 10% per annum. He said that improvements in vgp-bps9a/b battery performance is often gradual and orderly progress, these advances are very flat and even, such as design thinner and lighter battery casing, thereby saving space.

For example, in January this year, Apple announced its iPhone, after the new product, the company’s engineers began looking for software products, whether the adjustment of this room, to reduce canon bp-511 battery usage. Apple’s iPhone, vice president of marketing operations Geruigeqiao Shiwei Ke, said: “This result is greatly increased talk time this product.
