“…The integration of the previously mentioned building block elements has resulted in the production of an integrated chip named 'Wirtx1' [16]. Wirtx1 is a "smart" wireless sensor chip prototype, a simplified block diagram of which is shown in Figure 5, that has been designed in a 0.5-µm Hewlett-Packard CMOS process which incorporates temperature sensors, a four-channel analog multiplexer to support multiple sensor inputs, a 10-bit A/D converter with bandgap voltage reference, a programmable spread-spectrum generator with selectable families of Gold-code polynomials, an integrated state-machine system controller, high-speed data modulator, and output RF power amplifier.…”

Researchers at Oak Ridge National Laboratory (ORNL) are developing selectively coated cantilever arrays in a surface-micromachined MEMS process for very high sensitivities in chemical and biological sensing. Toward this end, we have developed a one-dimensional (1-D) 10-element microcantilever array that we have coated with gold for mercury sensing and palladium for hydrogen sensing. Ultimately we will coat each element with a different coating. Currently, measurements have been performed using a companion analog 1.2-µm CMOS eight channel readout chip also designed at ORNL specifically for the microcantilever arrays. In addition, we have combined our sensors with an ORNL-developed RF-telemetry chip having on-chip spread spectrum encoding and modulation circuitry to improve the robustness and security of sensor data in typical interference-and multipath-impaired environments. We have also provided for a selection of distinct spreading codes to serve groups of sensors in a common environment by the application of code-division multiple-access techniques. Our initial system is configured for use in the Scientific, and Medical (ISM) band. The entire package is powered by four AA batteries.

Low-cost Sensors for Balancing Indoor Air Quality and Energy Usage

Saving energy and improving indoor air quality (IAQ) and thermal comfort in buildings are traditionally competing goals. Facilities that manage one of these objectives tend to compromise the other. Building automation systems (BAS) have been limited in their ability to sense these characteristics of a building and therefore cannot act on them. A majority of buildings defi ne IAQ in terms of supply air temperature alone, and manage energy consumption by scheduling. There is a large potential to improve both IAQ and energy consumption through innovative control strategies. These strategies are independent of developments in the energy conversion equipment itself by enhancing its control. Good control requires good feedback, and feedback for IAQ is complicated by a lack of sensors able to be easily integrated into BAS that can record other contributions to IAQ such as CO 2 and the presence of trace gases. Since BAS have not traditionally had access to these types of data, there is little experience of how to best apply this new information in a dynamic system to achieve reduced energy consumption while improving IAQ. This article will discuss development and integration of low-cost microsensor arrays into affordable BAS. Multi-function sensor packages are in development that can measure CO 2 , temperature, humidity, room occupancy, and potentially other trace gases of interest. The sensor package can communicate with the BAS wirelessly or over existing building power wiring. Communications have been developed for a low-cost implementation with algorithms focused on security and robustness.

“…HE recent technological advances have allowed the development of complex Systems on a Chip (SoC) for such diverse applications as smart sensors [1], telecommunications or multimedia [2]. Most of these systems integrate heterogeneous blocks such as micro processors cores, digital signal processors, RAM/ROM memories, analog to digital converters… Furthermore, communications between a SoC and its environment often require the design of mixedsignal IPs (Intellectual Properties) such as bus interfaces (IEEE1394, USB,…) or wireless transceivers [3] [4] (IEEE802.11b, Bluetooth,…).…”

We present the design of an Intellectual Property (IP) modeling the interface controller for an inter-integrated controller channel (I2C) bus. AMS IPs such as bus interfaces, whose behaviour follows the bus protocols in terms of packet structure, timing constraints or control modes can offer solutions for the issue of communications between a System on a Chip and its external environment. The model of our controller is written in SystemC in association with a SystemC-AMS description of the analog block. Simulation results are presented.
