Abstract: The present application describes a method and system for determining a time delay between a transmission and a reception of an RF signal in a noisy environment. The method comprises: transmitting the RF signal; shifting a phase of the RF signal after a first time period of the transmitting of the RF signal, starting at a known transition time; receiving a received RF signal comprising a received phase shift corresponding to the shifting of the phase of the transmitted RF signal, the received phase shift occurring at a receive transition time equivalent to a sum of the time delay and the known transition time; determining the receive transition time by detecting a time corresponding to the received phase shift; and calculating the time delay using the receive transition time and the known transition time.

Abstract: There present description is directed to a method and a system for determining a time delay between a transmission and a reception of an RF signal in a noisy environment. The method comprises: transmitting the RF signal according to a transmit frequency pattern, the transmit frequency pattern comprising at least three pulses separated by a period of time, each one of the at least three pulses respectively being at each one of at least three different frequencies; receiving a received RF signal comprising the at least three pulses at the at least three different frequencies, each one of the at least three different frequencies associated to a receive phase change; comparing the receive phase change of one of the at least three different frequencies with the receive phase change of another one of the at least three different frequencies to obtain a dispersion phase difference; and calculating the time delay using the obtained dispersion phase difference.

The hand grip and the clamping device are adjustably connected such that the hand grip may be adjusted in both height and angular orientation relative to the bath tube sidewall when the bath tub rail assembly is attached thereto.

Abstract: An apparatus (10) for bagging material into a stretchable bag having an open end, comprises a movable bag stretching structure (18) displaceable between a first position for receiving the bag and a second position for holding the bag in a stretched state, wherein said stretching structure (18) is provided with elongated corner members (70, 72) for accumulating the bag thereon, each of said elongated corner members (70, 72) being provided with a movable strap-like member (210) extending along the length of the corner members (70, 72) to facilitate loading and unloading the bag on and from the corner members (70, 72).

Abstract: Polymer composite films were prepared by solvent casting suspensions of quantum dots (QDs) in cellulose triacetate (CTA) solution. The films were robust and possessed the optical properties characteristic of QDs. Transmission electron microscopy (TEM) images of the films revealed that the QDs were well dispersed within the CTA film matrix. The selective alkaline hydrolysis of QD/CTA films in 0.1N NaOH over 24 hours resulted in the surface conversion of CTA to regenerated cellulose. Optical properties of the films were probed both before and after the hydrolysis reaction using fluorescence spectroscopy, and were found generally unaltered. The cellulose surfaces of the alkaline treated films allow for facile incorporation of the films into paper sheets.

Abstract: A periodically shieldable solar structure (10) comprises a cavity formed between a pair of light transmitting members (12). A foam insulation/shading system (14) is provided for periodically filling the cavity with degradable foam. The foam insulation/shading system (14) comprises a series of foam generators (28) mounted within the cavity and distributed therealong to provide multiple foam generating points therewithin. The foam generators (28) are operatively coupled to a source of pressurized air and a source of foaming solution.

Abstract: There is described herein a method for detecting anomalies in an infrastructure, the method comprising: providing a computationally-intelligent analysis model to model a behaviour of at least one detection instrument in said infrastructure; inputting control instrument data into said analysis model, said control instrument data being provided by control instruments in said infrastructure; outputting an estimated behaviour for said at least one detection instrument from said analysis model; comparing actual data from said at least one detection instrument to said estimated behaviour and generating a set of residuals representing a difference between said actual data and said estimated behaviour; and identifying anomalies when said residuals exceed a predetermined threshold.

Abstract: There is described a method and system for detecting an anomaly in data originating from a component used in an industrial process. The anomaly detection steps comprise: providing predictive models in which at least one of the predictive models corresponds to at least one operating mode from a plurality of operating modes of the component; obtaining operating data from the component, the operating data being indicative of a given operating mode from the operating modes; selecting at least one of the predictive models based on the given operating mode; generating estimated data using the selected at least one predictive model; comparing the operating data with the estimated data; and generating an alarm trigger when the comparison meets a given anomaly criteria thereby constituting the detection of the anomaly.

Abstract: A method and system for detecting change to a record in a file stored on an electronic token involves storing a change detection code (CDC) so that a change detection applet can calculate a current CDC for corresponding record(s), and compare the current CDC with the stored CDC to determine if data has changed. Any changes to records are registered by a registering element that provides a service feature, back-up of the file and/or synchronizes the file with other files stored remotely. One use of the method is to back-up phonebook records on USIM/SIM cards.

Abstract: The present invention relates to a brush cutting head for a brush cutter. The brush cutter head includes a cylindrical support body that has a first end, an opposed second end and an intermediate portion extending therebetween. The intermediate portion has a curved surface that defines the circular cross-section of the cylindrical support body. A plurality of collars is mounted to the cylindrical support body at spaced intervals along the intermediate portion. Each collar extends radially from the curved surface of the cylindrical support body. Additionally, each collar cooperates with an adjacent collar to define a mounting station between the adjacent collars. The brush cutter head further includes a plurality of cutting tooth assemblies carried on the outer surface of the cylindrical support body. Each cutting tooth assembly has a cutting tooth for placement within the mounting station and a mounting assembly engageable with the adjacent collars to secure the cutting tooth in the mounting station.
