A specially designed police car in the Holland Tunnel, NY.
Patrolmen who regulate the flow of traffic through the Holland Tunnel recently tested a miniature electric car that rolls along the tunnel’s “catwalk”. The car is designed to give the officers greater control over traffic by permitting them to cover tunnel posts faster. It was tested on a 2200-foot run of miniature railroad track. Only two feet wide, the 1300 pound car can be driven in either direction from a swivel seat inside the glass-enclosed cab. Push buttons control the speed at six or twelve miles per hour. A 240-volt, three-horse-power motor powers the car.

World War One US body armor, circa 1918
The Experimental Light Body Armor 1917-1918 was developed by the US Ordinance Department. The adjustable steel plates were held together with leather straps, and had a one-inch thick rubber sponge backing. The .04 to .036 inch-thick manganese-alloy plate was proof against pistol rounds and shrapnel, and potentially rifle fire at extreme ranges. The weight of breastplate and backplate combined was 8-1/2 pounds. The arm-guards weighed 2-1/4 pounds each. The Experimental Helmet No. 5 which was intended to combine the best protection of German type helmets with the ease of production British type helmets held, was 2-1/3 pounds in weight. None of these pieces would enter general service before the war’s end.
