Title: Tx line driver with common mode idle state and selectable slew rates
Inventor: BOECKER CHARLES W
IPC: H04L27/10
Filed: 2004-09-10
Abstract: A transmit line driver with selectable slew rates and a common mode idle state comprises a capacitor array (186) of selectable capacitors coupled between a line driver (184) and a pre-driver (182) wherein a slew rate may be selected by the selectable capacitors. A common mode idle state is provided by coupling a selectable switch (214, 215) (MOSFET in the described embodiment) to a mirror device (198) that provides a bias current to the pre-driver wherein, when the bias current is removed by the switch, the pre-driver produces an output signal that is equal to the supply voltage for the circuit.  Accordingly, a differential pair (202, 204) of the line driver are both biased on and provide a common mode idle state. The common mode idle state is equal to one half of an output signal magnitude for a logic one.

Patent CA-2544688-A1 (CA)
Title: Cellular membrane protein assay
Inventor: EGLEN RICHARD M
IPC: G01N33/53
Filed: 2004-11-03
Abstract: Methods and compositions are provided for determining cell membrane protein populations in the cell membrane of a cell and changes in the population due to changes in the environment or status of the cell. The methods employ a cell having a fusion construct of the cell membrane protein linked to a signal producing peptide through an exofacial protease recognition site or sites. The signal producing peptide is either an enzyme fragment capable of binding to a second enzyme fragment to form an active enzyme when released from the cell membrane or has two binding sites, where the complementary binding entities are related in that a signal is produced when the two entities are in proximity. For the enzyme signal producing peptide, by adding the protease to the cell and the second enzyme fragment and substrate, one can determine the cell membrane protein population and the effect of changes in the cell environment on such population. Similarly, by adding the two entities and any other necessary reagents, a signal is produced whereby one can determine the cell membrane protein population and the effect of changes in the cell environment on such population.

Patent CA-2549658-A1 (CA)
Inventor: MIKKELSEN SUSAN R
IPC: G01N27/26
Filed: 2004-12-03
Abstract: A method for the phenotypic identification of microorganisms is provided. The method is based on the evaluation of the effects of various compounds (effectors) on the respiratory cycle activity of microorganisms. Measurements are based upon the ability of the microorganism to transport electrons to an external chemical oxidant (a mediator) that is added to the microorganism sample. The mediator interacts with the terminal components of the respiratory pathway and the extent of its consumption is related to the ability of the microorganism to respire. The consumed mediator is subsequently measured electrochemically. Electrochemical signals which are generated in the presence or absence of an effector can be used to generate a signal pattern that is unique to an organism and can be used for identification.

Title: Slurry dewatering and conversion of biosolids to a renewable fuel
Inventor: DOOLEY BRIAN
IPC: C10L7/00
Filed: 2005-11-08
Abstract: In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and/or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

Abstract: An apparatus and method for determining the phase fraction of a fluid collected downhole is shown comprising an x-ray generator, a filter, a sample cell, and a radiation detector. The filter produces a radiation spectrum with a high energy portion and a low energy portion. Filtered radiation is passed through a sample fluid and the resulting attenuated radiation signal is used in calculating the phase fractions of oil, water, and gas in the sample fluid. In one embodiment, a second reference radiation detector measures the radiation directly from the x-ray generator and this measurement is used in normalizing the fraction result. The ratio of the high energy signal to low energy signal of the reference detector is used in controlling the input voltage of the x-ray generator thus ensuring a stable spectrum.
