Abstract: An infection sensing system that comprises a wearable sensor device configured to be fastened onto skin. The sensor device has a sensors including a temperature sensor, a heart rate sensor, and a reflective SpO2 sensor. A multivariate time-series analysis neural network trained to perform temporal pattern recognition, generates an output that predicts infection. The neural network processes time series data that extends over a duration of at least one hour. The time series data representing body temperature, heart rate, and SpO2 level input into the multivariate time-series analysis neural network comprises data that comprises substantially simultaneous measurements for at least the heart rate and SpO2 level.

Abstract: A carrier to carry user belongings for a security screening system e.g. of an airport. The carrier comprises a token reader to wirelessly read a user token to determine a user token identifier, and a carrier identifier to distinguish the carrier from amongst the multiple carriers of the security screening system. The carrier identifier is stored in the carrier. A carrier controller is configured to read the user token of a user issued with the carrier to carry their belongings, to determine the user token identifier of the user, store the user token identifier read from the user token, read the stored carrier identifier, and transmit the stored user token identifier in association with the stored carrier identifier.

Abstract: An infection sensing system for determining whether a human or animal user has one of a plurality of infection conditions in response to a sensed condition of the user. The system includes a remote temperature measuring subsystem comprising a first, imaging sensor to capture a first image of a body part, a thermal imaging camera to capture a thermal image of the body part, and an image rocessor to process the first image to identify when the body part is present in a field of view of the thermal imaging camera. The system is also configured to determine one or more biomarker values for one or more further characteristics of the human or animal user. machine learning classifier processes the body temperature and further characteristic(s) to identify one of the infection conditions.

Abstract: An infection sensing system includes a sensor device configured to be fastened onto the skin, the sensor device including multiple sensors and a processor coupled to the sensors. The sensors include at least a temperature sensor to read skin temperature as a proxy for body temperature and a heart rate sensor. The processor inputs data from the sensors, determines data representing body temperature and heart rate, and identifies a combination of: (i) a greater than threshold temperature fluctuation in the body temperature, and (ii) a greater than threshold heart rate, where (i) and (ii) are present for greater than a threshold time duration. Responsive to this identification the system outputs data indicating infection.

Abstract: We describe a sensor system for measuring relative distance between sensors of the system, the sensor system comprising at least two sensors, wherein each said sensor comprises an RF transceiver coupled to a microprocessor and stored program code for controlling the microprocessor, wherein said stored program code comprises code to: send, using said RF transceiver a group of one or more data bits from the sensor to a second sensor; receive, using said RF transceiver, an acknowledgement of reception of said group of data bits from said second sensor; determine a time difference between said sending and said receiving; compensate said time difference from a processing delay by the microprocessor of said second sensor between the second sensor receiving said group of data bits and sending said acknowledgement, to determine timing data reprinting distance to said second sensor.

Abstract: We describe a method of manufacturing a plurality of electronic devices. The method comprises manufacturing a multi-device motherboard bearing programmable device circuit boards, each of these with an electronic device comprising a processor and programmable memory and being detachable from the motherboard except for one of more frangible links, at least one of these links comprising a programming connection. A device programming region bears a motherboard processor and program memory for programming the device circuit boards. Code for at least one application program for said electronic device is stored in said motherboard program memory. A user interface for the multi-device motherboard allows a user to configure each of the electronic devices to perform a defined function.
