Abstract: A system for facilitating construction of a deck comprises a server, a client computer, and a database. A user inputs, through a graphical user interface on the display of the client computer, a configuration for the deck. The server receives the deck information from the client computer and determines, based on information in the database and the deck information, a parts list and instruction information. The instruction information includes information on the alterations to the parts needed to construct the deck. The parts list and the instruction information may be displayed on the user interface.

Abstract: There is provided a vehicle (18) comprising a propulsion unit (34) configured to move the vehicle (18) and to change a characteristic of the environment of the vehicle (18). The vehicle (18) further comprises a proximity sensor (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31) configured to detect the characteristic of the environment of the vehicle. The characteristic of the environment is changed by operation of the propulsion unit (34). The vehicle (18) further comprises obstacle detection circuitry (32) configured to determine a presence of an obstacle in the vicinity of the vehicle based on a comparison between the detected characteristic of the environment and a reference value.

Abstract: A safety auditor is designed to perform opening and closing of every safety switch that is used in an industrial bakery oven. Every pressure sensor can be tested for on and off states. The low gas pressure switch can be vented and the high gas pressure switch pressurized. All thermocouples associated with the high temperature circuits are tripped. Fans are started and stopped over a communications signal or via the hard-wired interface as required to generate the safety testing. Once the safety testing is complete, the results along with time, date, name of tester, pass or fail will be printed out via a small kiosk printer. This ticket can then be filed in an office. As the operation is easy to do and requires little effort, it is much more likely to be performed and therefore safer for the host bakery.
