Embedded Electronics Technology in Automobiles

As automobiles become increasingly user-independent and ‘intelligent,’ the demand for embedded electronic devices for use in cars is steadily increasing. This was indicated by increased demand for printed card buses (PCBs) that were destined for use as embedded devices in automobiles. PCB production rose in several parts of Europe, and experts in the industry are predicting moderate growth worldwide in the near future. Embedded systems, because of their small size, low power consumption and rapid response rates have become valuable to the automotive industry as parts of safety components, sensors and on-board computers.   Virtual Mechanisms Powered by Embedded Systems Car manufacturer, Porsche, in cooperation with dSPACE of Germany, has developed an electronics system that simulates the forces at work when one shifts gears. The shift force simulator simulates the normal operating conditions of a car from a driver’s perspective. Available inputs include the gear stick and pedals. Data from those input methods are then fed into a computer, which calculates the appropriate type and amount of feedback to the user.

The Wellness Mobile Phone

The Wellness mobile phone from the Japanese mobile solutions provider, NTT DoCoMo and Mitsubishi Electric Corporation was launched at the Combined Exhibition of Advanced Technologies (CEATEC), which was held in Japan on the first week of October this year (2007). According to the company spokesman, the Wellness mobile phone is a device that is suited to busy yet health-conscious individuals as health and fitness checks can be provided on the go using a very convenient device. Traditional Fitness Features The Wellness mobile phone is equipped with a pedometer that uses a built-in motion sensor. This motion sensor can detect the number of steps, the distance traveled and the type of activity (running, walking or climbing) being done by the phone user. Using all collected by the motion sensor, the inbuilt programming can calculate the amount of calories that has been burned. The phone can then generate a daily activity summary. The phone also has a body mass calculator function. This function also does not require any input from the user. For the calculation to ensue, the phone user is only required to hold the phone at arm’s length. The phone also comes equipped with a sensor to measure the user’s…

The Digital House

The development of new tech-based products and systems has given rise to new ways to do business. Moreover, continuous drops in prices of these products and systems as well as their increased versatility have made integration of traditional gadgets possible. Merging devices has resulted to flexible, multi-functional business and/or entertainment systems that are capable of sharing, retrieving, and transferring digitized information among devices – and they do so with utmost control, convenience and security. Digitized Home A new tech-based segment in the market is gaining more popularity in businesses and households because of its simple yet flexible applications; functions that could change the way people communicate, transfer information and enjoy the comforts of their home are being developed. Digital home is a term that refers to a system where data and information storage, sharing and transfer (using networks of various devices and computers) exist. It is usually comprised of three main components: the servers, the players, and the controllers.

The Autonomous Flying Ambulance

The autonomous flying ambulance, nicknamed the Mule, is a creation of Rafi Yoeli, who used to work for Boeing and Israeli Aerospace Industries. He later founded his own company, Urban Aeronautics, in Yavne, Israel. The Mule is the smaller version of another Urban Aeronautics product, the X-Hawk. The former vehicle has been designed for the purpose of carrying injured military personnel (hence the name ‘flying ambulance’) out of combat areas, while the latter is aimed for urban and personal use.   Several of Yoeli’s patented inventions are integrated into the Mule, including his VTOL (vertical take-off and landing) vehicle technology and the hybrid drive-powered lift platform. Both the Mule and the X-Hawk, for instance, are classified as VTOL vehicles.

How to use inline ASM using WinAVR

I have been working on optimisation of one of my C codes. I needed one function to be as optimal as possible. I decided to use inline ASM to achieve this. I decided to write few lines about this. There are few rules that is necessary to follow. Each ASM statement is divided by colons into 3(up to four parts): Assembler instructions part; A list of output operands (comma separated); A list of input operands (comma separated); Clobbered register – usually left empty.

Design and Implementation of DTMF Detector

Basic Extension Module for Embedded System Prototype By: Ivan Christian adn Daniel Widyanto < p class=”Section1″> Introduction Telephone units are ubiquitous. They can be found in almost every house. In some houses that has many rooms a line is paralleled so that anybody can receive and make call from different rooms. Their presence could be used for other purposes instead of making call per se. Application of this module can be found in smart home automatic system which incorporates telephone unit as input module. By using telephone unit somebody can make a control action to a remote system, as far as the telephone line can reach. To do so, such an interface between telephone line and the control system is needed. DTMF Detector 2.0 is designed for the purpose. 1. Description DTMF Detector 2.0 is a microcontroller system extension module which detects the presence of DTMF tones, and then decodes the tones to coded binary digits. By using DTMF Decoder 2.0 design engineer could interface the analog signal of telephone line with digital logic of microcontroller system in straight ahead manner. 2. Module Specifications The module specifications are as follows: 1. Input: · DTMF tones from telephone line (analog signal)…
