Abstract: A traffic control system and device is provided. The traffic control system of the instant invention permits two-way communication between a plurality of traffic signal devices and/or other devices or locations. Each traffic signal device locally controls the state of the traffic signals, while communication between the traffic signal devices is used to synchronize the internal timers or clocks of the plurality of traffic control devices.

Abstract: Preparation time of a multi print head screen printing machine is reduced by inputting the printing parameters into an electronic storage device on the silk screen when carrying out test printing, to avoid rekeying the information at the print head. The storage means can be accessed by cable connection or wireless connection.

Abstract: A method of operating a screen printing machine of the type where a number of garments supported on pallets sequentially move past a series of printing stations. In order to allow a sufficient delay between each print application the garments pass around the stations several times and in each lap only some of the colors are printed. The sequence is controlled by tracking the first garment and by activating counters at each active print head as the first garment arrives. The program allows for one process to complete while another commences and thus provides improved productivity.
