Abstract: An apparatus comprising: at least one photoplethysmography sensor configured to determine pulse information of a user; at least one audio sensor configured to determine heart sound information of the user; and means for determining, based, at least in part, on the pulse information and the heart sound information, blood pressure information of the user, wherein the at least one photoplethysmography sensor and the at least one audio sensor are comprised in an ear-worn device.

Abstract: An apparatus, method and computer program is described for: receiving, over a period of time, a signal indicative of a pressure measured by a pressure sensor of an earpiece, the earpiece comprising an ear tip configured for insertion into an ear canal of a user, wherein the pressure sensor is arranged to measure a pressure within the ear canal whilst the ear tip is inserted into the ear canal; determining one or more characteristics of the signal; and determining a measure of a quality of a seal between the earpiece and the ear canal based on the one or more characteristics.

Abstract: A wearable objective pain measuring device includes a headband configured to be worn by a user on the user's head. The device includes one or more sensors in the headband, including one or more of: a sweep impedance profiling sensor to collect data reflective of activity of corrugator supercilia during a pain session; an electromyography sensor to collect data signals from a brain that reflects pain perception; a photoplethysmogram sensor configured to collect data regarding changes in hear rate and heart rate variability due to pain state; or a galvanic skin response sensor configured to collect data related to changes in sweat gland and skin conductance due to a pain state. The device includes a pain quantification pipeline to objectively quantify pain based on data from the one or more sensors. The device includes an output device configured to output an objective pain quantification based on quantifying pain.

Abstract: A respiration rate measurement apparatus including a plurality of sensors for concurrently generating temperature, pressure and acoustic data representing one or more successive breaths and a method of generating fusion data from the plurality of data streams as a weighted average based on determined correlation coefficients and calculation of a respiratory rate.

Abstract: One aspect of the invention provides a device for passive detection of the presence of a drone. The device includes: an antenna; a receiver in communication with the antenna to passively receive wireless signals; and a processor in communication with the receiver and programmed to determine whether a drone is present based on a pattern in the wireless signals emitted from the drone that is correlated with a physical movement of the drone. Another aspect of the invention provides a method for passively detecting the presence of a drone. The method includes: receiving a wireless signal at a device comprising an antenna, a receiver and a processor; and analyzing the wireless signal to determine whether the wireless signal includes a pattern in the signal that is indicative of a physical movement of a drone.

Abstract: A wind and solar power plant, producing electrical energy at any scale, site, and level above the ground, and with almost no wind, comprises rotor trains, mounted on decks of a garage-like building, each rotor train having a plurality of rotors positioned between a shroud and a wind tunnel. The wind is accelerated in a low middle part of the wind tunnel while flows from a high entrance towards a higher and wider exit. The blades of the rotors protrude into the middle part of the wind tunnel causing fast rotation of the rotors around horizontal axes. A super-diffuser, a booster and a wind tunnel are increasing the power of the wind and rotors in hundreds of times. Each rotor train comprises up to six rotors connected with twelve electrical generators. Electrical energy can be also produced by solar panels, mounted on the balconies and on the roof of the building.
