Title: Log debarking apparatus
Inventor: WEIRATHMUELLER FRIEDRICH
IPC: B27L1/00
Filed: 1996-07-03
Granted: 1999-08-24
Abstract: An improved log debarking apparatus characterized by a pair of shafts with cleated wheels for supporting and rotating a log under a rosser type debarking tool. The improved log debarking apparatus further has a plurality of log lifters movably supported about a common axis, and each having a profiled upper edge engageable transversally with a lower surface of a log on the cleated wheels. There is also provided a first lifter actuating means for alternately turning the log lifters from a retracted position below a radial projection of the cleated wheels, to a raised position above the cleated wheels,and into a log ejecting position wherein each profiled upper edge is inclined for rolling the log along and away from the cleated wheels. There is further provided a second lifter actuating means for moving the plurality of log lifterslongitudinally relative to the shafts. The present invention also relates to a method for debarking a log, comprised of the following steps: raising the log above the cleated wheels; moving the log until a large lump on a surface of that log is positioned beside any of the wheels; laying the log back onto the wheels; and rotating the wheels and the log, and debarking the log.

Title: Co-channel interference reduction
Inventor: TONG WEN
IPC: H04B1/12
Filed: 1996-10-09
Granted: 2001-03-20
Abstract: Co-channel interference of a frequency modulated signal represented by complex signal samples is reduced by amplitude limiting each sample and non-linearly filtering the limited samples. The non-linear filter low pass filters the limited samples, multiplies the filtered samples by their complex conjugates, and high pass filters the products to produce resultant signal samples. It also squares the filtered samples, low pass filters the squared samples, multiplies the filtered squared signals by the complex conjugates of the filtered samples, combines the result with said resultant signal samples and the filtered samples, and low pass filters the combined signal to produce samples having reduced co-channel interference. The limiter and non-linear filter can be constituted by a digital signal processor.

Patent CA-2218242-C (CA)
Inventor: FYFE KENNETH RICHARD
IPC: G01C22/00
Filed: 1997-10-09
Granted: 2005-12-06
Abstract: A device comprised of at least a pair of accelerometers and a tilt sensor mounted in fixed relation to a datum defining plane (sole of a shoe) maybe used for extracting kinematic variables including linear and rotational acceleration, velocity and position. These variables may be resolved into a selected direction thereby permitting both relative and absolute kinematic quantities to be determined. The acceleration is determined using a small cluster of two mutually perpendicular accelerometers mounted on a shoe. Angular orientation of the foot may be determined by double integration of the foot's angular acceleration (which requires a third accelerometer substantially parallel to one of the two orthogonal accelerometers). The two orthogonal accelerations are then resolved into a net horizontal acceleration or other selected direction which may be integrated to find the foot velocity in the selected direction.      The average of the foot velocity corresponds to the subject's gait speed.

IPC: H04W72/04

Abstract: A typical feature of high-speed data transmission in a cellular radio environment is that it is strongly unidirectional. In accordance with the present invention, a connection can be adapted to this fact so that the connection is asymmetric, providing a large transmitting capacity in the direction in which the most of the data stream is passing, whereas in the opposite direction, the transmitting capacity is smaller. The transmission and reception time-slots are arranged asymmetrically so that transmission and reception do not take place simultaneously. Upon establishing a connection, the mobile station informs the network of its maximum capacity regarding reception and transmission, whereby the network calculates an appropriate time-slot configuration. First, a symmetric connection consisting of a specific number of channel pairs is allocated in the same way as in a prior art HSCSD  method. Thereafter, only the required time-slots in the transmitting and receiving directions are used, still keeping the unused time-slots allocated.

Abstract: A platform for implementing interactive voice response (IVR) applications ov er the Internet or other type of network includes a speech synthesizer, a gramm ar generator and a speech recognizer. The speech synthesizer generates speech which characterizes the structure and content of a web page retrieved over the network. The speech is delivered to a user via a telephone or other type of audio interfa ce device. The grammar generator utilizes textual information parsed from the retrieved web page to produce a grammar. The grammar is supplied to the speech recognizer and used to interpret voice commands and other speech input generated by the user. The platform may also include a voice processor which determines which of a number of predefined models best characterized a given retrieved page, such that the process of generating an appropriate verbal description of the page is considerably simplified. The speech synthesizer, grammar generator, speech recognizer and other elements of the IVR platform may be operated by a Internet Service Provider (ISP), thereby allowing the general Internet population to create interactive voice response application s without acquiring their own IVR equipment.
