Patent CA-2174680-A1 (CA)
Inventor: AMRANY DANIEL
IPC: H04L27/00
Filed: 1996-04-22
Abstract: Apparatus that realizes a substantial advantage by employing implied interleaving to create a systematic interleaver, that can result in a superior block error rate compared to the current data interleaving techniques in which uncorrected error bursts are distributed by the deinterleaver. The disclosed principles lead to a embodiments that essentially eliminate transmitter memory regardless of the interleaving approachemployed. By way of example, block interleaving (regular or random), convolutional interleaving (regular and random) and product interleaving approaches are described. In implied interleaving, all incoming data is treated as if it is pre-interleaved and transmitted directly to its destination without alteration to its sequence, and essentially without delay. Concurrently with the transmission of the data, the data is applied to apparatus that treats the data as if it had been interleaved in accordance with a selected interleaving approach and, in accordance with such treatment, redundant symbols are generated and inserted into the transmitted data stream. At the receiver, the incoming data is delayed, corrected, and the information symbols in the incoming data are delivered to the user, corrected as necessary, in the same order as the information symbols arrived at the receiver.

Patent CA-2179211-A1 (CA)
Inventor: COHEN WILLIAM W
IPC: G06N5/02
Filed: 1996-06-17
Abstract: Efficient techniques for inducing rules used in classifying data items on a noisy data set. The prior-art IREP technique, which produces a set of classification rules by inducing each rule and then pruning it and continuing thus until a stopping condition is reached, is improved with a new rule-value metric for stopping pruning and with a stopping condition which depends on the description length of the rule set. The rule set which results from the improved IREP technique is then optimized by pruning rules from the set to minimize the description length and further optimized by making a replacement rule and a modified rule for each rule and using the description length to determine whether to use the replacement rule, the modified rule, or the original rule in the rule set. Further improvement is achieved by inducing rules for data items not covered by the original set and then pruning these rules. Still further improvement is gained by repeating the steps of inducing rules for data items not covered, pruning the rules, optimizing the rules, and again pruning for a fixed number of times. The fully-developed technique has the O(nlogn) running time characteristic of IREP, but produces rule sets which do a substantially better job of classification than those produced by IREP.

Title: Low Power Magnetometer Circuits
Inventor: HAWKS TIMOTHY J
IPC: G01R33/02
Filed: 1995-06-08
Abstract: Magnetometer circuits are disclosed in which a solenoidal sensor coil (3) including a saturable core (2) is provided with a source potential (Vs) to bring the coil towards saturation, followed by deactivation of the potential to the coil. The current through the coil is sensed and the magnetic field effecting the coil may be determined based on the amount of time which is required for the current in the coil to decline from a first level to a second level. A current sensor (4) connected to the sensor coil provides a first output signal in response to the current through the coil increasing to a first value in a first portion of an operational cycle, and provides a second output signal in response to the current through the coil decreasing to a second value. The time period between the first and second output signals from the current sensor is indicative of the magnitude of the field affecting the coil.

Title: Flexible downloading of software
Inventor: DAHLIN MATS HAKAN
IPC: G06F9/445
Filed: 1996-01-30
Abstract: In a networked system, such as a telecommunications system, having a first node coupled to a second node, a technique of supplying one or more wanted software files to the second node starts with the first node retrieving a menu of software file identifiers, wherein each software file identifier identifies a corresponding one of a plurality of software files. The software file identifiers are then sent to the second node, where each is examined, and for each a response is formed. The response, which indicates whether the corresponding one of the plurality of software files is alternatively wanted, or not wanted, is then sent back to the first node. The first node examines the response and retrieves the wanted software files. The retrieved software is then sent from the first node to the second node. In another aspect of the invention, the indication of "not wanted" may be expanded to include an indication that an offered file is "already loaded", or "forbidden to be loaded". In yet another aspect of the invention, the steps of offering a menu, receiving a response, and transmitting the wanted files is repeated in each of two phases, so that in a first phase, the second node can request that a more complicated bootstrap program be downloaded and started. Then, during the second phase of downloading, the more complicated bootstrap program running in the second node makes the decisions about what further subfiles to accept from the first node.
