  • Patent number: 10378937
    Abstract: A method for clustering of transient signals is provided. The method comprises the steps of acquiring the transient signals as they come, dynamically building up clusters of similar transient signals in a hyperspace based on comparison and clustering rules so that each new one of the transient signal acquired ends up in a cluster with similar transient signals formerly acquired, analyzing the clusters to determine respective signatures defined by the transient signals gathered in the clusters, and processing the signatures to detect a phenomenon connectable to an intrinsic attribute of the transient signals.

    Abstract: A nerve integrity monitoring device includes a control module and a physical layer module. The control module is configured to generate a payload request. The payload request (i) requests a data payload from a sensor in a wireless nerve integrity monitoring network, and (ii) indicates whether a stimulation probe device is to generate a stimulation pulse. The physical layer module is configured to (i) wirelessly transmit the payload request to the sensor and the stimulation probe device, or (ii) transmit the payload request to a console interface module. The physical layer module is also configured to, in response to the payload request, (i) receive the data payload from the sensor, and (ii) receive stimulation pulse information from the stimulation probe device. The data payload includes data corresponding to an evoked response of a patient. The evoked response is generated based on the stimulation pulse.

  • Patent number: 10357170
    Abstract: A method, system and apparatus for determining the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state. A signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state.

    Abstract: A method for treating patients with sensor agnosia is described that uses a gaming system with a specialised two handed game controller that can provide isolated haptic feedback to the patient's hand that has the greatest sensory agnosia. The controller is designed to be easy to use for patients with limited dexterity and requires the user to use both hands to control the controller. The gaming system provides a range of interactive computer games that provide contextually relevant haptic feedback of varying durations and intensities. Haptic feedback is provided in response to events in a game, and whilst the controller requires two hands, each hand is vibrationally isolated so that haptic feedback is only provided to the desired hand. The system logs usage statistics of the patient and these can be sent back to a clinician for analysis. The system and controller is particularly suitable for children with Cerebral Palsy, but may be used to treat patients with sensory agnosia due to range of conditions.

  • Patent number: 9763823
    Abstract: A system and method are provided that employ a monitoring device to monitor at least one patient physiological response to a change in temperature of the patient (e.g. pursuant to induced hypothermia therapy), wherein a monitoring signal is provided by the monitoring device. In turn, an output (e.g. a visual and/or auditory output) may be provided to a user indicative of at least one measure of patient response to the change in temperature. Alternatively or additionally, a processor may be provided to process the monitoring signal and provide an output employable by medical personnel to control a patient shivering response to the patient temperature change. Such information may comprise information regarding one or more anti-shivering medicament(s), e.g. corresponding dosage and/or frequency information for use by medical personnel in the administration of the anti-shivering medicament.

  • Patent number: 9706962
    Abstract: A wearable device has user movement sensors and core contraction sensors. Signals from the sensors are transmitted to a processor which analyzes the movement signals and determines when a qualifying movement is performed which benefits from core contraction. Signals from the core contraction sensors are also transmitted to the processor and are used to determine if the core is contracted during the qualifying movement. If the core is contracted during the qualifying movement, the movement is a protected qualifying movement. However, if the core is not contracted during the qualifying movement the movement is an unprotected qualifying movement. The system can inform the user when unprotected qualifying movements are performed.

  • Patent number: 9597002
    Abstract: A stochastic Bayesian non-linear filtering system and method that improves the filtering of noisy signals by providing efficiency, power, speed, and flexibility. The filter only requires the likelihood function p(observation|state) to determine the system state and works in various measurement models. This allows for the processing of noisy signals to be used in real time, such as in a biofeedback device that senses noisy surface electromyography muscle electrical activity, filters the sensed signal using the nonlinear filtering method, and provides vibrations based on the muscular activity.

  • Patent number: 9585622
    Abstract: A filter apparatus (100) having a signal input (101) to which an input signal is applied which contains a useful component and a noise component, a fast signal path (102) and a slow signal path (103) arranged in parallel therewith. The fast signal path and the slow signal path are coupled to the signal input. The fast signal path contains a filter in order to prompt fast filtering of the input signal. The slow signal path contains a filter in order to prompt slow filtering of the input signal. An output of the slow signal path is coupled to the fast signal path by means of a signal line (106). A signal output (104) which is coupled to the fast signal path has an output signal applied to it which essentially contains useful components of the input signal.
