Opening up an M2M device A
wireless applications using industry standard C code. With conventional M2M solutions, an external CPU must be
connected to the modem in order to control it – but the Telit AppZone shifts this capability into the module itself, reducing hardware cost and saving space on the PCB. In addition, it makes application development easier because
Noise reduction for intercoms: the easy- to-install, self-powered Muta device
DSP-based audio noise suppressor A
new audio device from dBD Communications can be fi tted to any intercom to reduce the ambient noise in the near vicinity, so that
communications can be heard and acted upon. Suggested environments where the Muta unit might be useful
include plant equipment, armoured vehicles, helicopters, aircraft marshalling and maintenance areas. The device is designed to be connected and disconnected with ease so that it can be fi tted only when needed. Among the features of the Muta box are:
• high performance DSP (Digital Signal Processor) with 20 dB (90 per cent) noise elimination
• wide frequency response for a more natural voice sound • auto power shutoff when there is no voice activity • auto power shutoff when the plug is not engaged into an active intercom
• lithium-ion battery giving at least 24 hours of continuous usage • failsafe design: the headset will work even though the power is not turned on.

developers need to master only one programming language – standard C – which is widely used and very powerful. Normally, application development requires different languages for the modem and the microcontroller. Telit AppZone is an open platform providing standard interfaces, allowing easy integration or porting of applications
from a different OS. It targets a wide range of markets, such as remote monitoring and control, security and
surveillance, telemetry, location services, billing, or fl eet management. •

Battery-free tower light F
batteries which must be replaced every 3–5 years, which can be a costly operation, particularly in remote locations. In addition, lead-acid batteries have a negative impact on the environment and need to be recycled with care. But the Obelux system has no batteries at all to replace. Energy is stored in super-capacitors which have an expected life-time of over 15 years. The controller, charger and capacitors are all integrated into one cabinet, making the system compact and easy to install. •

he new Dolphin 7800 ‘enterprise digital assistant’ (EDA), from Honeywell, packs the features and functions of a traditional data collection device, including the ability to withstand daily use in demanding mobile applications, into a rugged yet easy-to-carry handset.
“Building on the overwhelming success of the Dolphin 99EX mobile computer, the Dolphin
7800 delivers many of the same technology advances and durability in a smaller form factor – which is just what our customers have been asking for”, said John Waldron, of Honeywell Scan- ning & Mobility. “We invite those who’ve traditionally considered the MC65 to try the 7800.” For users of rival EDA products, Honeywell believes the new machine can reduce their
failure rates by as much as 80 per cent. Features of the Dolphin 7800 include
• the ability to withstand accidental drops to concrete from as high as 1·5 m as well as more than 1000 tumbles from 1 m;
• built-in Wi-Fi and a software-defi nable radio that allows switching among cellular carriers; • a powerful processor and network connections that enable multi-tasking for productivity; • advanced scanning and image capture performance; • an outdoor-viewable 3½-inch display.
