Patent CA-2331995-A1 (CA)
Title: Equaliser for digital communications systems and method of equalisation
Inventor: HUDSON JOHN E
IPC: H04B1/707
Filed: 2001-01-22
Abstract: Equalisation of a communication channel is achieved through use of a Wiener filter frequency response mechanism that operates to transform both the received data and the channel impulse response into frequency domain representations using a Fast Fourier Transform (FFT). Subsequently, spectral equalisation of data spectra and a channel spectrum in the frequency domain yields an equalised packet spectrum that can be converted back into the time domain by an inverse FFT function. Ratio comparison of the data spectra with the channel spectrum and conversion back into the time domain equalises the channel to appear as white toy resolving-induced inter-symbol interference. Matrix manipulation, i.e. transformation, of STTD samples (in the form of real and imaginary vectors) incident to a receive antenna allows FFT processing of encoded data, initially presented on either a chip-wise or symbol-wise basis in an information slot or packet. The matrix manipulation defines a set of samples seen at the receive antenna in terms of both a complex multiplexed transmitted sample sequence sent from a plurality of sources across separate paths that are affected by respective channel impulse responses. Operating a FFT regime in the frequency domain avoids extensive signal processing requirements associated with joint detection algorithms in high data rate application, with processing load made independent of channel impulse response duration. The principle of applying Fourier transformation techniques in equalisation is also applicable to systems employing multiple transmit elements and multiple receiver elements, such as in space-time coding (STC) schemes.

Title: Apparatus for detecting hydrocarbons using crystal oscillators within fuel dispensers
Inventor: KOCH WOLFGANG H
IPC: G01N29/036
Filed: 1999-08-06
Abstract: A vapor recovery system (18) utilizes a crystal oscillator (30) for sensing the presence of hydrocarbon in the vapor emissions emanating from a fuel tank (10) during refueling. The crystal oscillator (30) is coated with a layer of material having a sensitivity for hydrocarbon. In response to any interaction between the coating layer and hydrocarbon, the crystal oscillator (30) experiences a shift in its oscillation frequency relative to the fundamental resonance frequency. The frequency shift (34) is representative of the hydrocarbon concentration in the vapor emissions. A control signal (36) based on the frequency shift (34) is generated and then used to adjust the operating speed of a vapor pump (26).

Title: A process for manufacturing potassium sulfate fertilizer and other metal sulfates
Inventor: HOLT TIMOTHY G
IPC: C01D5/00
Filed: 2001-08-29
Abstract: A new process of preparing potassium sulfate fertilizer and other metal sulfates from the chlorides and other halides of these metals. The process utilizes the discovery that sulfur dioxide or trioxide, when introduced as a fluidizing medium into shallow beds of the halide salts at moderately elevated temperatures ( 1000°F - 1150°F) in a counter current process results in the conversion of the metal halides into metal sulfates and the halide gas. The process is carried out in a series of true fluidized beds preferably but not necessarily arranged in a vertical configuration so that the solids flow downward due to the fluidized process and the sulfur dioxide or trioxide gases flow counter currently in an upward direction producing pure metal sulfates at the bottom and pure halide gas at the top.
