New Products

摘要

In this issue, we review two products that enhance vehicular transportation: a Bluetooth audio head unit that seamlessly integrates with mobile phones and a system that: uses mobile phone network usage data to determine average traffic speeds and areas of congestion. We also report on a laptop and related WiFi technology that significantly tower the barrier to such technologies' use in developing countries and a device that helps soldiers disarm landmines. We describe Ballbot, a battery-operated omnidirectional robot that moves by balancing dynamically on a single urethane-coated metal sphere. We also report on wireless memory chip, called memory spot, that contains a built-in antenna and can store up to several Mbytes of data
