  • Patent number: 9123254
    Abstract: A method, a system, and a computer program product for creating and conducting a survey are disclosed. While creating the survey, one or more answer formats corresponding to each of the one or more questions are defined. Then, answering mediums corresponding to each of the one or more answer formats are defined. The survey is then created based on at least one of the questions, the answer formats, and the answering mediums. The survey is then available to the associated users. While conducting the survey, the system receives answers for the questions in the survey through the answering mediums in their associated answer format, and compiles a survey report.

  • Patent number: 8594554
    Abstract: A system that avoids any stopping or reversing of the web direction in a continuous feed printer, instead maintaining consistent process speed, only requiring a slowing and speeding up of the web to cycle through the PR belt seam. This is done by forming a web loop and then immediately flattening the loop after passage of the seam through the transfer zone that includes two transfer BTR rolls with alternating transfer operations, but simultaneous transfer for short periods. Two vacuum assist rolls, one located between the two bias transfer rolls controls the formation of the web loop. A pair of nip forming rolls upstream of the first transfer station and a second vacuum assist roll downstream of the second transfer station control the size of the loop.
