A program editor creates a program-edit screen for a control system based on element data for representing circuit elements and operators and their attribute values. The detector includes a sequence table and comparison circuitry for comparing a sequence of data samples that includes previous and subsequent data samples with allowed sequences determined from the sequence table. According to a method, positional information that specifies a longitude and latitude at a plurality of times is received and processed to generate a routing graph. The device includes a first chamber that encloses a first region of a profile and a second chamber that encloses a second region of the profile, wherein different temperatures can be set in the first and second chambers. The packaging system specifically tailors microperforated containers and packaging for particular produce to optimally preserve the produce, using a method of making registered microperforations on the packaging material using a CO2 laser and a sensor mechanism. In a typical embodiment, individual components of a proposed deployment pattern are identified and then evaluated against previously approved deployment patterns.
