Title: Absolute property measurement with air calibration
Inventor: WASHABAUGH ANDREW
IPC: G01N27/02
Filed: 1998-10-28
Abstract: An instrument and method for providing accurate and reproducible measurement of absolute properties of a material under test without using conductiv-ity or crack calibration standards. The instrument has a sensor designed to minimize unmodeled parasitic ef-fects.   To accomplish this, the sensor has one or more of the following features: dummy secondary elements located at the ends of a primary winding meandering, setting back of the sensing element from a connecting portion of the primary winding, or various grouping of secondary elements. The sensing elements of the sensor can be connected individually or in differential mode to gather absolute or differential sensitivity measurements.  In addition, the instrumentation is configured such that a significant portion of the instrumentation electronics is placed as close to the sensor head to provide inde-pendently controllable amplification of the measurement signals therein reducing noise and other non-modeled effects.

Abstract: A special service mail form constructed of a sheet of paper and a backing sheet adapted to simplex printing so as to allow use of the special service mail form is a self-help, kiosk. The sheet of paper is divided into two sections by a line of weakness. The first section provides a return post card having printed indicia on the front surface associated with special service mailers such as PS Form 3811.  The second section includes two adhesive backed removable labels. Return address information is printed onto one of these two labels. To assemble a special services mailer, the return address label is removed from the remainder of the sheet of paper and applied to the appropriate area on the back of the return post card. The backing sheet is attached to a back surface of the sheet of paper to protect the adhesive applied to the back of the labels from exposure prior to their detachment from the remainder of the sheet of paper.

Patent CA-2336099-A1 (CA)
Title: Method of encoding bits in a signal
Inventor: MILLER MATTHEW L
IPC: H04N1/387
Filed: 1999-04-16
Abstract: A message in the form of a sequence of bits is encoded into non-binary signals. The encoder (401) encodes the message into a vector as the first half of the eventual encoded vector, and append the negation of the encoded vector to the encoded vector as the second half to obtain the full-length encoded vector. An identical synchronization signal (405) is added to both halves of the encoded signal. During decoding, the decoder (501) first obtains the synchronization signal by adding the two halves of the vector to find the original cyclical shift of the vector. Afterwards, the decoder decodes the vector into a bit sequence by taking the difference of the two halves of the full-length encoded vector. Finally, the encoder re-encodes the bit sequence and compares the resulting vector with the original vector to determine whether the original vector truly encoded or was simply a noise signal.
Patent CA-2338618-A1 (CA)
Title: Digital watermarks and methods for security documents
Inventor: RHOADS GEOFFREY B
IPC: G06V30/40
Filed: 1999-06-24
Abstract: Security documents (e.g. passports, currency, event tickets, and the like) are encoded to convey machine-readable multi-bit binary information (e.g. digital watermark), usually in a manner not alerting human viewers that such information is present. The documents can be provided with overt or subliminal calibration patterns. When a document incorporating such a pattern is scanned (e.g. by a photocopier), the pattern facilitates detection of the encoded information notwithstanding possible scaling or rotation of the scan data. The calibration pattern can serve as a carrier for the watermark information, or the watermark can be encoded independently. In one embodiment, the watermark and the calibration pattern are formed on the document by an intaglio process, with or without ink. A photocopier responsive to such markings can take predetermined action if reproduction of a security document is attempted. A passport processing station responsive to such markings can use the decoded binary data to access a database having information concerning the passport holder. Some such apparatuses detect both the watermark data and the presence of a visible structure characteristic of a security document (e.g., a printed seal of the document's issuer).
