Filed:

Apr 23, 2008

Appl. No.:

12/108325

Inventors:

Todd N. Radtke - Hastings MN, US
Philip R. Moulton - Faribault MN, US
Craig Emmerich - River Falls WI, US
Robbie A. Neilsen - Prior Lake MN, US
Hugh Eugene Watson - Prior Lake MN, US

Assignee:

SCANTRON CORPORATION - IRVINE CA

International Classification:

G06F 3/033
G06F 3/048

US Classification:

178 1901, 715764

Abstract:

Implementations feature scannable form techniques and systems. Some aspects feature an apparatus that includes a pen-camera device, an electronic clipboard to store the pen-camera device, and a docking station for the clipboard. The clipboard includes a retention clip to hold a form on a substantially planar surface, and a pen-camera storage compartment to store the pen-camera device. The clipboard includes a power supply interface for charging the pen-camera device, a communication interface to transmit image and location data from the pen-camera device, and electrical interfaces for the clipboard docking station. The pen-camera device can mark response data on the form, optically scan response data and location data on the form, and associate time-stamped information for the marked responses on the form for error checking and fraud detection. The scannable form can include an area for encoded information that identifies a location and arrangement of a position-coding pattern on the form.

US Classification:

Abstract:

Implementations feature scannable form techniques and systems. Some aspects feature a scannable form including at least one response column parallel to a first longitudinal edge of the scannable form, and a broken ladder having two substantially parallel lines with locations for multiple rungs corresponding to encoded information that identifies a person assigned to the scannable form. A top rung is positioned on the scannable form so that the top rung can be a first rung that is scanned by a test scoring machine for the broken ladder, and a bottom rung is positioned so that the bottom rung can be a last rung that is scanned by the test scoring machine for the broken ladder. Other aspects feature a method to determine correct scoring key data in the test scoring machine for a test, and a method of transmitting information between the test scoring machine and a portable memory device.
