Abstract: A system (10) is for performing ECG measurements and comprises a probe (12) with an integrated one or more ECG electrodes (22) and an ultrasound sensing means (18), such as a transducer arrangement. The probe thus provides a mobile ECG electrode which can be sequentially moved between a set of different locations on the body for acquiring ECG measurements from different angles relative to the heart (i.e. different ‘leads’). Positioning of the probe in each required location is guided by a position guidance function which uses ultrasound data acquired by the ultrasound sensing means to locate the probe (with reference to an ultrasound body atlas (28) or map), and uses a stored set of reference body locations to guide a user with guidance information as to how to move the probe to arrive at a next target electrode location. In examples, the user may be guided through a sequence of electrode locations, with ECG data acquired at each one, thereby sequentially building up a set of standard ECG lead measurements.

Abstract: An ultrasound transducer unit (12), e.g. probe, is configured with a friction guiding function. The transducer unit (12) comprises a vibration generating means (20) at a tissue contact area, and has means for sensing a sliding direction of the transducer unit across a tissue surface (42) at which the contact area is incident. The tissue surface may be an external skin surface or an internal tissue surface, e.g. in case of a catheter. A control means is operable to control the vibration of the vibration generator to adjust a level of friction at the tissue contact area. This is used by the control means to implement a friction guiding function for guiding a user in sliding the unit across the incident surface, e.g. toward a target location (44), based on controlling the friction level responsive to sensed sliding direction, for instance providing lower friction when sliding is in a target direction, while leaving other directions with relative higher frictional resistance.

Abstract: According to the present invention, there is provided an air-frying cooker (1) comprising: a cooking chamber (20); a food receiving container (5) in the cooking chamber (20) having a permeable bottom wall (9); a heater (19) for heating air in the cooking chamber (20); a fan (18) for circulating a flow of hot air in the cooking chamber (20) to cook the food; and a system (13) to maintain a predetermined level (LI) of water in the cooking chamber (20) during cooking. The predetermined level (LI) is disposed between a base (11) of the cooking chamber (20) and the bottom wall (9) of the food container (5).

Abstract: The invention provides a food preparation vessel (100) comprising a main inlet (10) for introduction of a food material into the food preparation vessel (100), wherein the food preparation vessel (100) comprises a gas flow generator outlet (21) and a gas flow receiver inlet (22), wherein the gas flow generator outlet (21) is configured to provide a gas flow (25) in the direction of the gas flow receiver inlet (22) and having a component parallel to the main inlet (10) when the gas flow generator outlet (21) is functionally coupled with a gas flow generator in operation.

Abstract: A fluid handling structure to confine immersion liquid in a space between a projection system and a facing surface of a substrate, of a table to support the substrate, or both, is disclosed. The fluid handling structure includes a transponder to dissolve at least some of the gas in a bubble in the immersion liquid or to control a bubble in the immersion liquid so that it avoids entering an optical path of a beam from the projection system.
