    Abstract: The present invention relates to determining a neural respiratory drive (NRD) in patients with chronic obstructive pulmonary disease (COPD) based on surface electromyography measurements taken from the intercostal muscles on the chest of a subject (100). An electromyography system is presented that comprises a first electrode (2′) and a second electrode (3′) for contacting a skin of a subject (100), and a recorder (4′) for recording an electromyogram between the first electrode (2′) and the second electrode (3′); wherein the first electrode (2′) comprises a first electrode area (2A) and a second electrode area (2B) for contacting the skin of the subject (100), wherein the first electrode area (2A) and the second electrode area (2B) are insulated from each other; and the recorder (4′) is configured to form a noise measurement between the first electrode area (2A) and the second electrode area (2B) of the first electrode (2′) for determining a contact quality of an electrode-skin contact of the first electrode (2′). According to further aspects, a corresponding electromyogram recorder (4′) for an electromyography system, a method for electromyogram measurements and a corresponding computer program are presented.

    Abstract: The invention provides an energy generation and/or conversion system and method wherein an electrical power generator is controlled to periodically alternate between a contact-mode, during which elements of the generator are brought into contact to induce a state of charging, and a non-contact mode, during which plates of the generator are separated from one another and electrical energy is generated through electrostatic induction. Timing and duration of contact and non-contact modes are controlled by a controller, or by user commands, in dependence on a charge state of the elements of the generator: In this way elements are controlled to come into contact only when surface charge has fallen below a certain level, and re-charging is necessary; contact time between the elements may hence be minimised—thereby minimising incurred noise and surface wear—whilst still maintaining a given desired threshold power output.
