Electronic Everything!

French service robotics company Robosoft has introduced a robot called Kompaï designed to assist elderly and disabled people and others who need special care. The mobile robot talks, understands speech, and can navigate autonomously. It reminds people of meetings, keeps track of shopping lists, plays music, and works as a videoconference system for users to talk with their doctors, for example. The video below is pretty awesome. It shows a senior at Broca Hospital, in Paris, interacting with the robot after receiving only a few minutes of training. The man asks the robot about the time, date, and whether he has any appointments that day; Kompaï gives answers in a computerized voice.

Cypress Semiconductor Corp. has launched a programmable product for data communication over existing power lines. The Powerline Communication product leverages the programmable analog and digital resources of Cypress's PSoC programmable system-on-a-chip architecture. It integrates multiple functions beyond communication, such as power measurement, system management and LCD drive. In addition to its flexibility and integration, the product offers greater than 97% packet success rates without retries and 100% success rates with retries built into the solution's coding, according to Cypress. It also offers the flexibility to communicate over high-voltage and low-voltage power lines for lighting and industrial control, home automation, automatic meter reading and smart energy management applications.

Google PowerMeter allows consumers to access their power consumption data through a secure, Web-based iGoogle™ gadget. As a Strategic Partner, Microchip incorporated the recently announced Google PowerMeter API to create a Reference Implementation, which makes it much easier to develop products that are compatible with Google PowerMeter. Microchip's Reference Implementation demonstrates the device's activation, data transmission and status messages using readily available Microchip development tools. It can be used as a template for developers' own designs.

Anyone can bake a cake, but while some chefs bake dry, uninspired bricks of dough, there are other chefs who make cakes we would die for. The ingredients may be the same, but the outcomes are so very different. This is also the case between average electronic products and world-class, market-changing products. One of the most recent technical sensations is the capacitive touch screen. But what makes some touch screen-based products amazing, while others get such poor reviews?

When considering the resolution required for an A/D converter (ADC) integrated in a microcontroller (MCU), embedded systems designers must balance cost and performance. Higher ADC resolution implies higher-cost MCUs, but in some cases you can use other features in the MCU to enhance the ADC performance via software. That approach lets you achieve higher resolution using an inexpensive integrated ADC. Here's how to use of oversampling to achieve extra bits of resolution for an ADC integrated in an MCU.
