IPC: G06Q10/10
Filed: 1999-10-28
Abstract: A method of automated data collection, analysis and reporting is described. A plurality of questionnaires each consisting of a number of questions are stored in a database. New questionnaires may be added or existing ones modified by contacting the database by telephone. In use, a respondent accesses the database by telephone. Once the respondent is connected, the respondent enters a code which identifies the respondent and the questionnaire to be completed. The questions of the questionnaire are "read" to the respondent by an interactive voice response which then prompts the respondent to enter a response. The response is recorded and the next question is then "read". The process is continued until the questionnaire has been completed. The results are then immediately analyzed and reported to a third party. For example, the responses of the latest respondent may be compared to the responses of all previous respondents or previous responses of the same respondent.      The report may be sent automatically, for example, by fax.

Patent CA-2289187-A1 (CA)
Title: Pilot signal detection system using band reject filter
Inventor: MYER ROBERT EVAN
IPC: H03F1/32
Filed: 1999-11-09
Abstract: A pilot signal detection system uses a band reject filter to reject the frequency band of at least one carrier signal to improve pilot signal detection. For example, in a feed forward distortion reduction system, the carrier signal(s) is on a main signal path along with a pilot signal which is injected into the main signal path at a frequency adjacent to the frequency band of the carrier signal(s). The carrier signal(s) and the pilot signal are amplified on the main signal path, resulting in distortion on the main signal path. To reduce the distortion from the main signal path, the feed forward distortion reduction system detects and reduces the pilot signal. To improve detection of the pilot signal, the pilot signal detection system provides a signal representative of the carrier signal(s) and the pilot signal with distortion from the main signal path onto a pilot detection path. A band reject filter on the pilot detection path rejects the frequency band of the carrier signal(s) while allowing the frequency of the pilot signal to pass through to pilot detect circuitry. Without the presence of the carrier signal(s), the pilot detect circuitry can more accurately detect the pilot signal on the pilot detection path. In response to the detected pilot signal, the pilot detect circuitry can provide control signal(s) to improve the reduction of the pilot signal by changing the relative phase and/or gain between the signals on the main signal path and the feed forward path. Thus, by improving the detection of the pilot signal, the pilot detection system improves the reduction of the pilot signal and thereby of the distortion.
