Patent CA-2275528-A1 (CA)
Inventor: FARMER MICHAEL EDWARD
IPC: G01S13/931
Filed: 1998-01-17
Abstract: An automotive radar incorporates a repetitive randomized equivalent LFM sequence of frequencies for improved immunity to jamming from other automotive radars. Each frequency in the sequence is of sufficient duration to travel round trip over the detection range of the radar. The Doppler shift in the received signal is estimated by performing a spectral analysis on similar frequency components of the received signal, and is then removed from the entire received signal. The received signal (202) is then reordered (204) so as to form an equivalent LFM received signal, and is compared with a similarly reordered image of the transmitted signal so as to estimate the range to the target (210). The randomization sequence, initial start frequency, or initial time of the repetivie sequence are varied to minimize the effects of jamming by other radars, and this variation can be directionally dependent.
Patent CA-2279076-A1 (CA)
Title: Signal distribution network
Inventor: ARANGUREN WILLIAM L
IPC: H04H20/76
Filed: 1999-07-28
Abstract: A signal distribution network in which signals are distributed via a primary signal distribution path. Television signals are transmitted in a first frequency band, telephone signals are transmitted in a second frequency band, and data signals are transmitted in a third frequency band. Bidirectional terminal adapters are connected to each endpoint of the primary signal distribution path. The terminal adapters connect to end user devices which receive signals from the primary signal distribution path. In addition, the terminal adapters connect to signal sources which provide the signals to be distributed via the primary signal distribution path. In one embodiment, television signals received from a CATV television network are received by a television distribution module. The television distribution module has one or more tuner/converters each of which tune to a desired channel, modulate the desired channel onto at least one predetermined distribution channel, and provide the signal to the primary signal distribution path via the predetermined distribution channel.  The total bandwidth of the primary signal distribution path can be substantially lower than the total bandwidth of the communication links providing the sources of signals entering the network. As such, the primary signal distribution path may be implemented utilizing a single pair of wires.

Patent CA-2285210-A1 (CA)
Inventor: ASHWORTH DAVID TREVOR
IPC: H04M3/50
Filed: 1998-03-12
Abstract: In making a long distance telephone call to a called party (14), a calling party (10) has the option of a time advice service. The time advice service is provided from an international switch (22) which can access a service control point (24) having an associated look-up table (26), speech recognition equipment (28), a tone receiver (30) and clock and recorded announcement equipment (32). At the commencement of the call, the calling party (10) indicates, for example, by dialling a predetermined code or speaking a predetermined command, that the time advice service is required. The calling party then dials all or part of the telephone number of the dialled party and the calling party is then advised of the time and location of the called party. The calling party then has an opportunity to provide confirmation that the calling party wishes to be connected to the called party. The calling party may provide such confirmation, for example, by dialling the remainder of the telephone number of the called party or by holding without hanging up. No attempt is made to establish a connection to the called party while waiting for such confirmation. If the calling party provides such confirmation, then a connection is established to the called party.
Patent CA-2285497-A1 (CA)
Title: Integrated semi-active seat suspension and seat lockup system
Inventor: VANDERMOLEN GARY L
IPC: B60N2/52
Filed: 1999-10-06
Abstract: The vehicle seat suspension system of the present invention utilizes an extensible linkage supporting a seat frame. Height adjustment of the seat frame on the extensible linkage is done through an adjustable air spring. Movement of the seat frame due to jostling of the vehicle is normally dampened using a variable damping rate, extensible shock absorber. The damping rate is essentially pushed in infinity, fully locking the shock absorber positionally in response to detection of an accident condition. In one embodiment of the invention, a bleed valve between the compression and rebound chambers of the shock absorber is closed to effect lock up. In an alternative embodiment, the electrorheological or magnetorheological working fluid of a shock absorber may be solidified to lock positionally the shock absorber.  Condition detection sensors include accelerometers and roll over detectors. To allow for the possible loss of vehicle power, the lock up signal is supplied by an independent power source.

Title: Ink-jet cartridge with pressure-adjustment means
Inventor: LIN FU-SAN
IPC: B41J2/175
Filed: 1999-10-20
Abstract: The present invention is about a pressure-adjustment means for ink jet cartridges. An element, which is an elastic air-bag, is employed inside the ink jet cartridge. The air inside the elastic air-bag is in ventilation with the air external to the ink jet cartridge. When the pressure difference between the air pressure inside the air-bag and the back pressure of the ink-cartridge undergoes changes, this elastic air-bag may then automatically adjust its own volume by expansion or contraction by virtue of its elastic structure, and in turn modify the ink volume inside the cartridge, so that the ink contained inside the ink jet cartridge is prevented from leaking while permitting the printhead to be able to continue releasing ink droplets outwards in spurts.

Patent CA-2296531-A1 (CA)
Inventor: KOCH RAINHARDT
IPC: C08B11/08
Filed: 1998-06-26
Abstract: According to the invention, samples of highly crystalline (80 %) technical cellulose with a degree of polymerisation of approximately 1500 were enzymatically pre-treated with commercial endoglucansases under various conditions before being chemically converted to substituted cellulose derivatives. Said enzymatically pre-treated cellulose samples showed a significantly (up to 222 %) higher degree of substitution compared with control samples which had been pre-treated with buffer without enzymes. The increase in substitution during the chemical reaction was observed in the presence of various quantities of alkali, but decreased with reduced quantities of alkali. It was possible to significantly reduce the quantity of alkali required (by 60 %) and still obtain the same degree of substitution by using the cellulose samples which had been pre-treated with endoglucanase compared with the cellulose samples which had been pre-treated with buffer only. It was also possible to further increase the substitution of the enzymatically pre-treated cellulose samples by reducing the proportion of water in the reaction mixture used in the chemical reaction.
