Abstract: A powdered scent compound and related methods of application for adhering the powdered scent compound to a desired application area. The powdered scent compound can comprise a porous carrier powder, an adhesive compound and a synthetic scent compound. The powdered scent compound is shelf-stable and convenient to apply, carry and store. Furthermore, the powdered scent compound can adhere to applied surfaces, thereby ensuring that powdered scent compound remains where it is applied, even in locations where the potential exists for the compound to drip or be blown from.

Abstract: A method for an ultrasonic time-of-flight flow meter (1) includes driving an ultrasonic transducer (2, 3) using a first waveform (V1(t)) for a first duration (?t1), the first waveform (V1(t)) configured to cause oscillation (21) of the ultrasonic transducer (2, 3). The method also includes driving the ultrasonic transducer (2, 3) using a second waveform (V2(t)) for a second duration (?t2). There is a discontinuity between the first waveform (V1(t)) and the second waveform (V2(t)). The second waveform (V2(t)) and the second duration (?t2) are configured to maintain a voltage (VT(t)) across the ultrasonic transducer (2, 3) within a predetermined range (VH, VL).

Abstract: An engagement index reflects a user's level of engagement with a digital resource. Actions of the user, such as the amount of time spent on a page, the number of pages accessed, the amount of time spent in a session, and the number and type of annotations made may be used as factors in the determination of the engagement index. Data values corresponding to one or more of the factors are received and are validated to eliminate any extreme values and to make the values comparable with one another. Different validation methods may be used for different factors. Once the data values are validated, weighting coefficients are applied to the validated values. The system then determines the engagement index by summing the weighted values. Once calculated, the engagement index may be aggregated with other engagement indexes or compared to engagement indexes for other users.

Abstract: A system for processing a signal from a sensor is described. The system comprises an analog-to-digital converter. The system is configured to vary a sampling rate of said analog-to-digital converter dependent on an expected shape of the signal.

Abstract: The present invention provides methods for determining a collision between a first deformable object and a second deformable object in a virtual reality simulation, the method including the steps of providing a first test capable of determining the proximity of the first object to the second object, providing a second test capable of determining the proximity of the first object to the second object, wherein the second test is more comprehensive than the first test, and wherein the second test is capable of being implemented once the first test returns a positive result. Since the more comprehensive test is implemented only when a collision is likely or imminent (as determined by the first test), the processor executing the simulation is not unduly burdened, and can devote resources to other tasks required by the simulation program.

Abstract: Distortion of an optical signal transmitted over a fibre optic link is characterized by a receiver including a photodetector for converting optical radiation into an electrical signal. A delay line delays the electrical signal. At least two delay line taps drive a register that stores plural values corresponding with different delayed replicas of the electrical signal. Signals commensurate with the values are externally provided to a signal distortion analyser for analysis of the values to determine the optical signal distortion.

Abstract: A method and apparatus for providing diagnostic features for an optical transceiver, in which the optical transceiver uses electronic dispersion compensation (EDC) in order to alleviate distortion of a signal caused by dispersion. A method and apparatus for monitoring the performance of an electronic dispersion compensator by monitoring one or more signals from the electronic dispersion compensator and generating an alarm in the vent that the performance of the electronic dispersion compensator falls below a certain threshold.
