Patent CA-2296537-A1 (CA)
Title: Cigarette making machine including band inspection
Inventor: ALEXANDER BOGDAN N
IPC: G01N21/89
Filed: 1998-07-10
Abstract: An optical inspection system mounts on a cigarette making machine (200) or like system, and detects the presence of bands (5) having irregular widths or spacings. In response to the detection of irregular bands (5) the optical inspection system instructs the cigarette making machine (200) to reject cigarettes which will be subsequently made from portions of the cigarette paper containing the irregular bands. The optical inspection system includes a sensor (210) which can accommodate different types of cigarette paper, and band material having varying reflectance properties. In operation, sensor circuitry detects the range of voltages produced by a sensor detector (210), and formulates a peak value (or average peak value) for the range of voltages. The circuitry then takes a percentage of this peak value to form a threshold value. This threshold value is compared with the AC signal from the sensor detector (210). If the AC signal exceeds the threshold, then the circuitry asserts a signal to indicate that a band is present. The output of the sensor is fed to a computer (212). The computer detects whether the bands detected by the sensor (210) have regular band spacing and width.

IPC: H04J13/16
Filed: 1998-07-21
Abstract: In a time gated frequency division duplexing (FDD) data communication system, the base station (4) transmits two data frames on the forward link to the first remote station (6a, 6b) and receives two data frames on the reverse link from the second remote station (6a, 6b) at the first time frame. At the second time frame, the base station (4) transmits two data frames to the second remote station and receives two data frames from the first remote station.  Data transmission and reception alternate over consecutive time frames. On the forward link, each data frame is covered with a unique Walsh code. The data is also spread with the short PNI and PNQ codes in accordance with the IS-95A  standard. The data can be scrambled by the long PN code. The base station (4) delays the long PN code and short PN codes and properly loads the Walsh codes so that the processed data can be properly demodulated and descrambled by the destination remote station (6a, 6b).

Title: System and method for imaging test answer sheets having open-ended questions
Inventor: GONZALEZ JOSE A
IPC: G06K17/00
Filed: 1998-07-13
Abstract: An imaging system includes two sets of cameras: a first set for capturing optical mark or optical character recognition data and a second set for capturing visual images. Full visual images of pages containing answers to open-ended questions are retained and are retrievable by a reader such that an area of interest wherein the answer is expected is displayed, but the remaining area is also available for viewing. The system permits the alignment of a page based upon edge detection if the page contains only an open-ended answer, obviating the need for timing tracks. Hardware and software elements cooperate to store the image temporarily in a server having a response time commensurate with the scanner. The image is then processed with the use of high-performance index imaging for optical storage and retrieval, and then routed to a long-term storage device.
