Abstract: Systems and methods are disclosed to provide a modulated stimulation signal to a patient, the modulated stimulation signal including a carrier wave modulated with a biological or natural frequency stimulation signal, to provide the benefit of the biological or natural frequency stimulation signal to the patient without the patient perceiving the biological or natural frequency stimulation signal.

Abstract: A hub, a system comprising the hub, a method of wireless communication channel selection and an associated computer program product, wherein the hub is configured for selective wireless communication over any channel of a plurality of wireless communication channels, the hub being configured to transmit a response request, the response request comprising a request for at least one or any device receiving and processing at least part of the response request to transmit a response over a listening period; during the listening period, listen to each channel of the plurality of channels; and determine an activity characteristic for each channel based, at least in part, on activity received by the hub on the respective channel during the listening period.

Abstract: An apparatus, method, and system for detecting an object in an environment. The apparatus comprises: a processor configured to: control an active reflected wave detector to measure wave reflections from the environment to accrue measured wave reflection data; process the measured wave reflection data to detect an object in said environment; in response to detection of said object, determine whether a first predetermined condition in respect of the object is met; and if the first predetermined condition is met, control an output device to output a deterrent.

Abstract: An apparatus, method and system for detecting an object in an environment. The apparatus comprises: a processor, the processor coupled to an active reflected wave detector that is operable to measure wave reflections from the environment. The processor is configured to: process measured wave reflection data to determine whether a predetermined condition is met, the measured wave reflection data accrued by the processor in response to the active reflected wave detector being activated in response to a motion sensor detecting motion in said environment; and if the predetermined condition is met, perform at least one operation related to camera image data.

Abstract: Embodiments relate to a device for mounting on a wall for monitoring an environment. In one embodiment the device comprises: a body comprising: an active reflected wave detector; and a processor coupled to the active reflected wave detector, the processor configured to: control the active reflected wave detector to measure wave reflections from the environment to accrue measured wave reflection data, and identify a status of a person in the environment based on the measured wave reflection data, wherein the processor assumes, for said identification, that the active reflected wave detector is at an operating height above a floor of the environment. The device comprises a cord extending from the body, the cord having a length for ending at the floor when the device is mounted with the active reflected wave detector at said operating height and the cord is freely hanging and straight.

Abstract: Embodiments relate to using an active reflected wave detector to classify the state of a person in an environment and optionally respond accordingly. In one embodiment there is provided a computer implemented method of determining a state of a person comprising: receiving an output of an active reflected wave detector; classifying a state of the person as being in a safe supported state based on the output using measurements of reflections associated with the person, wherein said classifying is based at least on: a height metric associated with at least one reflection from the person conveyed in the output of the active reflected wave detector; and a plurality of velocity magnitude measurements of the person corresponding to different times, each of said velocity magnitude measurements determined using the reflections associated with the person conveyed in the output of the active reflected wave detector.

Abstract: Embodiments relate to a device and method for determining a status of an environment and/or a status or condition of a person therein. The method may comprise: receiving an output of a sensor to monitor said environment; commencing a time window after the sensor detects activity in the environment; upon expiry of the time window, activating an active reflected wave detector to measure wave reflections from the environment, the detector consuming more power in an activated state than the sensor in an activated state; and determining a status of the environment and/or of a person therein based on an output of the active detector indicative of one or more of the measured reflections. The method comprises delaying expiry of the time window in response to the sensor detecting activity in the environment during the time window.
