DEWALT DC759KA 18-Volt NiCad 1/2-Inch Cordless Drill/Driver Kit

Unable to ship rechargable battery packs with drills. Hoping to ship drills and place batteries in my luggage. Is this feasable? Legal?

A: Yes, but don't put them in your check bag.

Handheld THz Instrumentation

Most companies offering THz products have been making the technology easier to use for non-expert operators by reducing the size, weight, and power requirements, improving the performance of emitters and receivers, and being sensitive to sample location and shape.

For instance, most commercially available THz systems are designed to operate on a laboratory bench or table, and samples have to be prepared and taken to the device. Furthermore, even relatively portable systems require supporting equipment and facilities such as wall-plug power.

However, in the last year, a Rensselaer-Zomega team has designed and built a fully integrated, turnkey, handheld, and battery-operated THz wave spectrometer, the micro-Z. The 5-pound device is the size of a cordless drill and was a finalist in the 2011 Prism Awards for Photonics Innovation.

Designed to be a lightweight tool for detection and identification of chemicals such as explosives and related compounds in the open field, this compact system is configured to work in normal-incidence reflection in a point-and-shoot fashion. It produces and measures pulsed terahertz waves from 0.1 to 3.0 THz using time-domain techniques in both transmission and reflection geometries, with a waveform acquisition rate of 500 Hz and a time delay >100 ps.
