Abstract: A mobile bullet-resistant barrier that has adjustable and removable bullet-resistant glass panes. The barrier includes a frame supporting a bullet-resistant material, slidable in the frame, the material being substantially transparent. The frame generally having a first frame side, a second frame side, the frame sides being substantially parallel to each other. Also, the frame includes a plurality of cross-tracks, the cross-tracks being perpendicular to the frame sides and connecting the frame sides together. Further, the frame includes a first base member and a second base member mounted perpendicular to the cross-tracks at an end of each frame side for carrying the frame sides. A plurality of locking rollers are mounted to the base members allowing frame movement.

Abstract: A safety garment having reflective properties and a multiple light assembly for lighting the safety garment. The reflective characteristics of the garment are carried out by the reflective material securely positioned on the garment. An electrical assembly is attached to the garment and comprises a battery, the multiple light assembly and a switch. The multiple light assembly is supported by the garment and sandwiched between the garment and the reflective material, making the multiple light assembly invisible when the multiple light assembly is not receiving power.

Abstract: A portable monitoring system for use at sites, such as construction sites, is provided. The portable monitoring system can provide enhanced security at such sites and may be quickly set up and taken down. A portable monitoring system, in accordance with one embodiment of the invention, includes a housing and a plurality of portable sensing devices and a plurality of mounting platforms both capable of being removably stored in the housing. The mounting platforms may be easily retrieved from the housing and disposed about the site and are each capable of detachably mounting one or more of the portable sensing devices. The portable sensing devices each include a sensor for sensing a stimulus and a transmitter, coupled to the sensor, for transmitting a signal associated with the stimulus. The housing further includes a communication system for receiving the transmitted signals from each of the portable sensing devices and communicating signals associated with the sensed stimuli to an external system.
