Abstract: Electromagnetic (EM) radiation eye protection systems (10) and methods are disclosed. The system includes an EM radiation source (20) and one or more pairs of protective eyewear (100). A control device (30) is operative to control the emission of an EM radiation beam (24B) from the EM radiation source in response to a transmit signal (WST1, ST1). Each pair of protective eyewear includes a sensor unit (120) that generates the transmit signal when the participant (P) properly wears the protective eyewear. The eye-protection system prevents the emission of the EM radiation beam if a participant is not wearing protective eyewear.

Abstract: A luggage with a deployable, wheeled undercarriage and movable handles. The undercarriage has telescoping support members that can be deployed or opened to carry additional baggage and closed when not required. Wheels on the support members allow the luggage to be moved along the floor without having to tilt the luggage. This increases the stability and the amount of baggage that can be added. The handles in the deployed configuration extend behind the luggage to facilitate pushing the luggage. Deployment of the undercarriage can be manual or automatic with actuation of a deployment member, such as the handle itself.
