Abstract: For determining a match factor regarding color match of a printed product with target values for colors, measuring fields of a printout are spectrally measured and actual measured values of the printout recorded. The target values are compared with actual measured values by determining for the printed product a color value axis from a unique color value as a start point to a second unique color value as end point and interpolation points between the first and second unique color values; determining target values for start and end points and interpolation points; determining actual measured values for start and end points and interpolation points of the printout from the actual measured values; determining a distance value representing the distance between target value and actual measured value for each start point, end point, and interpolation point; and calculating and outputting the match factor as statistical average of the distance values.

Abstract: A wheelchair lifting device is disclosed. The wheelchair lifting device has a stationary platform, a movable lift assembly, a number of motorized lifting jacks, a foot stand platform, a battery power supply and a wireless lift controller and receiver. The movable lift assembly is attached to the stationary platform by the lifting jacks, and the movable lift assembly can be lifted and lowered relative to the stationary platform by the lifting jacks. The base of the movable lift assembly may be level with or nearly level with the stationary platform when in a lowered position to enable a wheelchair to roll onto the lift assembly without requiring a ramp. In some embodiments, the wheelchair lift includes a scale to weigh the occupant.

Abstract: A cannulated marker device for use in a spinal fixation procedure, particularly for insertion of pedicle screws, is disclosed. The marker device is configured to be inserted over a guide wire or directly with an insertion device into the spinal bone at a desired location, and left in place without interfering with subsequent steps of the spinal fixation procedure. Also provided, is an insertion device comprising a shaft attached to a handle at a first end, and a second end being configured to be detachably attached to a marker device of the present invention. A method for marking a location on a patient's spinal column is also provided in connection with the marker device and the insertion device of the present invention.
