1. RFID

O laboratório dispõe de kits da Texas para desenvolvimento sobre a tecnologia RFID.

"O sistema de identificação por rádio-freqüência (RFID) se sobrepõe às limitações de outros sistemas de identificação automática, executando leitura ou gravação, e/ou alteração de dados com o tag em movimento, não necessitando de uma linha de visão direta entre a antena do leitor e o transponder (tag). Isto significa que o sistema trabalha efetivamente em ambientes excessivamente sujos, com poeira, graxa, umidade, baixa visibilidade, e ainda consegue a comunicação através de quase todas as superfícies não-metálicas.

TI-RFID é uma solução altamente confiável para se detectar, rastrear e controlar eletronicamente uma grande variedade de itens. A alma do sistema é um transponder (RFID tag) que pode ser fixado ou embutido nos objetos. Uma das características mais importantes do sistema é que o transponder não necessita de baterias de alimentação, tornando sua vida útil praticamente indeterminada. Os dados coletados do transponder pelo leitor podem tanto ser enviados diretamente a um computador através de interface padrão, quanto serem armazenados em um leitor portátil e depois descarregados em um computador para processamento."

2. Bluetooth

O laboratório possue kits da Ericsson para o desenvolvimento sobre a tecnologia Bluetooth.

"BluetoothTM wireless technology revolutionizes the personal connectivity market by providing freedom from wired connections - enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. Interface, synchronize, exchange? All of the above, and more. Bluetooth technology redefines the very way we experience connectivity."

3. RF-Monolithics

Também tem kits para desenvolvimento de transmissão de dados wireless para pequenas distâncias RFM (alternativo ao Bluetooth).

"Low-power radio systems typically transmit less than 1 mW of power and operate over distances of 5 to 100 meters. Once certified to comply with local low-power communications regulations, these systems do not require a license or "air time fee" for operation. There are more than 40 million products manufactured each year that utilize low-power wireless technology for data links, telemetry, control and security. New applications for low-power wireless are emerging continuously. RFM’s Virtual Wire® product line has been developed specifically to support these low-power wireless requirements."

4. Serial Data Acquisition & Control Interfaces - Ontrack

"Serial based data acquisition is an alternative method of data acquisition and control using a computer serial communications ports ( RS232, RS485 ) as opposed to ISA, PCI or other bus-based hardware. Data acquisition via RS232 or RS485 typically involves sending and receiving ASCII data via a com port to external measurement and control hardware. There are several advantages and disadvantages to using serial data acquisition ( ADR ) interfaces."

5. Kits para desenvolvimento utilizando microcontroladores Ubicom

"For wireless access and networked device manufacturers, Ubicom provides Internet access Processors and Software that form a disruptive platform. Ubicom’s Software System On a Chip technology reduces time to prototype to a matter of days and time to production to twelve weeks. It is also half the cost, one-third the power and one-tenth the size of traditional SOC (system on a chip) based solutions. Unlike SOCs from Atmel, Motorola, TI and others, Ubicom delivers a complete, flexible and Internet upgradeable platform including an optimized processor, operating system, networking software, and multiple physical layers which can be leveraged across our customer's entire product portfolio."

6. TINI: Tiny InterNet Interface

"Tiny InterNet Interface (TINI) is a platform developed by Dallas Semiconductor to provide system designers and software developers with a simple, flexible and cost effective means to design a wide variety of hardware devices able to connect directly to corporate and home networks. The platform is a combination of a small but powerful chipset and a JavaTM-programmable runtime environment. The chipset provides processing, control, device-level communication and networking capabilities. The features of the underlying hardware are exposed to the software developer through a set of Java application programming interfaces.
The primary objective of the TINI platform is to give everything from small sensors and actuators to factory automation equipment and legacy hardware a voice on the network. This allows the devices to be monitored, controlled and managed remotely. The combination of broad-based I/O capability, a TCP/IP network protocol stack and a powerful object-oriented programming environment empowers programmers to quickly create applications that provide not only local control of, but also the ability to remotely manage, TINI-based devices. TINI's networking capability extends the connectivity of any attached device by allowing interaction with remote systems and users through standard network applications such as Web browsers.

The DS-TINI-1 is a compact (31.8 mm x 102.9 mm) 72-pin SIMM board. It is an Ethernet-ready hardware implementation and supports all of the following features:

Hosts the TINI runtime environment in a validated hardware design

10 Base-T Ethernet for networking

Extensive I/O capabilities of the DS80C390 microcontroller exposed through Java™ APIs

Dual serial ports

Dual 1-Wire® net interfaces

Dual CAN (Controller Area Network) controllers

2-wire synchronous serial bus

General-purpose digital I/O

Easy system expansion using parallel bus interface

Real-time clock for time stamping

Flash ROM for storage and execution of runtime environment

512K/1 Mbyte nonvolitile SRAM provides fast, unlimited write operations and persistent data storage

Level translator provides RS232 voltages

Wide operating temperature range, -20°C to +70°C

Requires only a single +5V power supply"
