Sep 28, 2004 — by LinuxDevices Staff — from the LinuxDevices Archive

A Bulgarian company has used the open source eCos operating system in a personal security device with a built-in GSM/GPRS cell phone and GPS (global positioning system) receiver. Media Systems Ltd.'s Personal Securer targets mobile operators wishing to offer tracking devices/services.

The Personal Securer will be available in October as part of a Starter Kit intended to help network operators integrate the device with their network services. Once integrated with backend telecom services, the device can provide vehicle tracking and personal safety alarm features to workers with dangerous jobs or those with medical conditions.

The Personal Securer includes a tri-band GSM module that has not yet gained approval for use in the United States, China, or Canada. It also includes a native 12-channel GPS receiver said to have snap, hot, warm, and cold start times of 3, 8, 38, and 45 seconds, respectively.

The device includes a speaker and microphone, and can be used to call two pre-configured numbers. The device can be configured to send GPS coordinates at intervals via SMS (simple text messaging) to cellphone recipients. A panic button can be configured to send GPS coordinates to two pre-defined numbers. And, the device can be used to provide GSM/GPRS connectivity to a computer attached via USB, Media Systems says.

The device includes a 3.7V 850mAh rechargeable Li-Ion batter said to provide 12 hours of standby, or 10 hours when sending SMS status messages every half hour. Voice call time is said to be 2 hours, and the battery has a claimed full-charge shelf life of 6 months when switched off.

The hand-sized unit weighs 94 grams. Additional features and accessories include a built-in alarm hooter, a native USB 1.1 interface, leather case, USB wall charger, USB car lighter charger, and PC and power supply connecting cable.
