Abstract: An apparatus including: a display configured to render display content over a field of view; and a glare system configured to render glare content in the field of view, wherein the glare system is configured to render the glare content at different positions across the field of view at different times while the display renders the display content.

Abstract: According to an example embodiment, a technique for data acquisition is provided, comprising: receiving, from an intermediate apparatus, a trusted aggregate data object comprising aggregate data object that comprises aggregate data comprising a respective trusted source data object for one or more data source apparatuses mapped to the intermediate apparatus and an intermediate apparatus quote that is descriptive of one or more aspects of a configuration of the intermediate apparatus upon production of the aggregate data, and an intermediate apparatus signature comprising a digital signature derived based on the aggregate data object using a first key assigned to the intermediate apparatus; and verifying, based at least in part on information received in the trusted aggregate data object, integrity of data included in the trusted aggregate data object and integrity of the intermediate apparatus.

Abstract: A method, apparatus and computer program, the method comprising: receiving a first biopotential signal obtained by a first capacitive sensor; receiving a second biopotential signal obtained by a second capacitive sensor, the first capacitive sensor and the second capacitive sensor being positioned at different locations on a subject; synchronising biopotential signals obtained by the first capacitive sensor and the second capacitive sensor by applying a time adjustment to biopotential signals obtained by at least one of the first capacitive sensor or the second capacitive sensor; wherein features in at least one of the first biopotential signal and the second biopotential signal are used to synchronise the biopotential signals obtained by the first capacitive sensor and the second capacitive sensor.

Abstract: An apparatus including at least one processor; and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to: control the magnitude of a stimulus applied by a stimulator to the skin of a human or animal body; and receive an output from a sensor configured to detect the response of a muscle in the human or animal body to the applied stimulus, the sensor output in combination with the magnitude of the applied stimulus enabling the sensitivity of the human or animal body to the applied stimulus to be determined.

Abstract: An apparatus including a nipple chamber having opposing first and second chamber ends, the chamber configured to receive a nipple of a mammary gland though the first chamber end and dimensioned to hold the nipple-end of a received nipple proximal to the opposing second chamber end, the second chamber end being substantially closed with one or more apertures therein to allow milk from the received nipple to flow out of the second chamber end and produce turbulence in the milk flow; and a microphone located proximal to the nipple chamber and configured to receive an acoustic signal produced by the turbulent milk flow in the nipple chamber.

Abstract: An apparatus including a body made of force-conveying material, wherein the body includes a nozzle part and a base part, the nozzle part protruding from the base part, and wherein the nozzle part is configured to fit at least partly into a mouth of a subject for feeding the subject, and at least one deformation sensor located in the base part, the deformation sensor being configured to sense, at the base part, deformation conveyed from the nozzle part through the force-conveying material.
