  • Patent number: 10603454
    Abstract: A tracheostomy tube assembly comprises an outer tracheostomy tube (1) and an inner cannula (20) fitted in the tube. The machine end of the inner cannula has a collapsible region (22) formed by a plurality of curved or bent struts (26) extending parallel with one another between a machine end collar (28) and a patient end collar (27). The struts (26) carry outwardly-projecting catches (23) arranged to engage a rib (24) extending around the inside of a hub (16) at the machine end of the tube and thereby resist removal of the cannula from the tube. The inner cannula (20) is removed by twisting the machine end collar (28) so that the struts (26) collapse inwardly and thereby disengage the catches (23) from the rib (24).

  • Patent number: 10489940
    Abstract: A system and computer-implemented method for improving the quality of images, such as images used in medical diagnosis. In a first technique, sinogram data, intermediate volumes, and transmission CT-based attenuation correction files are created. Scatter correction is performed, and a scatter correction map is created. Misregistration offsets are measured, and a correction registration mask is created using volume reprojection. The two masks are combined and applied to create the enhanced image data. In a second technique, a difference may be determined for each parent and child pixel pair, and an average difference may be determined for all pairs. For each pair which is under the average difference, the child may be eliminated and replaced with a new child. This process may be iteratively repeated, with the image data being incrementally enhanced with each iteration. For both techniques, the enhanced image data may be communicated to an interpretive application for display.

  • Patent number: 6701133
    Abstract: A method and apparatus is provided for locking a local oscillator to a reference oscillator. The reference oscillator is arranged to transmit a signal containing two reference pilot tones in a signal sideband. The apparatus samples the received signal and makes a frequency shifted copy where the shift is equal to the expected separation between the reference tones. The non-shifted and shifted signals are then combined in the frequency domain to constructively reinforce one of the reference pilot tones which is then searched for. Once the tone has been identified, a correction to the local oscillator frequency is calculated. The apparatus may be of particular use in a radio telemetry system in which it is important that the frequency of the local oscillators in the transmitters and receivers are very accurately matched to each other and where, in order to reduce interference, all the clocks used in the system are locked to a master clock.

  • Patent number: 6580320
    Abstract: The predistortion circuit (200) predistorts the input signal to a non-linear signal processing device in order to linearise its output. The predistortion circuit (200) derives the predistortion by sampling the input at (210) and multiplies it with itself using mixers (multipliers) (220, 226, 230, 236, etc.) in order to generate various orders of distortion (212, 214, etc.) which are summed to provide the predistortion. Filter/time delay means (240, 242, 244) are incorporated in the paths which generate the orders of distortion in order to introduce a phase and/or amplitude variation with frequency into the distortion. The filter/time delay means can be implemented by adaptive filters in digital signal processing circuits (DSPs). The DSPs can sample the output of the signal processing device being linearised in order to obtain feedback for adapting the filter(s).

  • Patent number: 5939951
    Abstract: An apparatus is disclosed for processing an input signal. The apparatus includes two feedback loops for generating output signal components from the input signal. Each loop contains an oscillator, which has a frequency or phase which is variable in response to a control signal, and a comparator for generating the control signal. The oscillator generates a loop output signal which forms one of the components of the output signal. The apparatus also includes a combiner for combining the loop output signals to produce the output signal. For each loop, the apparatus also produces a feedback loop operating signal, these signals being dependent on the output signal and in phase quadrature with one another. One input of the comparator in each loop receives the feedback loop operating signal, and the other input of the comparator receives a component of the input signal.

  • Patent number: 5134630
    Abstract: In deriving a control signal for recombining the parts of the spectrum separated by a frequency notch in transparent tone-in-band signals, cross-correlation products give rise to undesirable frequency and phase jitter. In a receiver which overcomes this problem an input signal E containing the notch is passed to two first mixers and then portions corresponding to the lower and upper portions of the input spectrum are selected by two mirror filters before being translated in frequency by two second mixers to a final output band in which the notch is eliminated. Two selection filters select parts of the spectra at the outputs of the first mixers which correspond to an overlap region of the said lower and upper portions when derived in a transmitter and apply them to a control-signal mixer. A control signal for the second mixers is derived from the output of the control-signal mixer by noise filtering and frequency division by two.

  • Patent number: 4947453
    Abstract: In transparent tone-in-band communication systems a notch in the frequency band is usually formed and then the resulting spectrum is translated in frequency to an intermediate frequency range as part of the transmission process. In a transmitter of the present invention a more simple arrangement is used in which the notch is formed directly in an intermediate frequency range by using mirror filters to divide an input signal into two portions and supply respective mixers, each having one output sideband in the intermediate frequency range. The mixers receive different reference frequencies and the mixer outputs are supplied to a summing circuit whose output is passed to a band pass filter to remove the unwanted sidebands. The original frequency spectrum is restored at the receiver by mixer processes of shifting the two selected sidebands similar to, but the inverse of, those used in the transmitter.
