摘要： A plural magnet arrangement of a matrix of rows and columns having an altered magnet field alignment of a plurality of the magnets in a matrix comprising rows and columns of magnets in such a manner that there are at times a co-existing combination of changing attractive and repelling magnetic field regions all throughout the coil winding volume, reducing the counter electromotive force (voltage) during electrically connecting a load to the coil winding terminals and extends the time duration of the output voltage waveform and this is accomplished wherein the rotational torque required to rotate the centre magnet through the coil of which it is centred within is reduced.

摘要： An axial field rotary energy device are disclosed. For example, the device can include a printed circuit board (PCB) stator having PCB panels. Each PCB panel can include conductive layers. Selected ones of the conductive layers are coupled to plated vias that extend from one major surface of the PCB stator to an opposite major surface of the PCB stator. In addition, each major surface of the PCB stator can have a layer of a dielectric material that completely covers ends of the plated vias.

摘要： A medical, motor-operated or hand-operated or operable instrument includes a number of bearings for supporting a shaft for applying torque to a tool, of which bearings at least two selected or selectable bearings form a bearing pair. A distance sleeve axially spaces apart the bearings of the bearing pair. The instrument includes a component located at least partly radially inside the distance sleeve. The component is or can be rotationally coupled to at least one of the two bearings to rotate together with a rotating part of the at least one of the two bearings, or to form a rotating part of the at least one of the two bearings. At least one permanent magnet is fastened or formed on or in the component. A coil is arranged on or in the distance sleeve.

摘要： A vibrational lens is disclosed. The vibrational lens comprises at least two focusing plates each having a proximal and distal end. The separation between the distal ends of the at least two focusing plates is less than the separation between the proximal ends of the at least two focusing plates. The vibrational lens transmits, converges and focuses vibrational energy from a source to an energy conversion means such as piezoelectric crystals. The vibrational lens may also comprise a bimetallic structure to convert thermal fluctuations into mechanical displacement. The vibrational lens is suitable for use in a vibrational and or thermal energy harvesting system. Advantageously, the vibrational lens improves the energy efficiency of, for example, an internal combustion engine whilst mitigating the need for vibrational damping mechanisms and or thermal insulation.

摘要： Energy harvesters (EH) which can effectively harvest wasted vibrational/kinematic energy and convert it into electrical energy for battery-free sensor operation are described herein. The energy harvesters can be integrated with a power management circuit and a wireless sensor for monitoring wind turbine blades. The target application of the energy harvesters includes powering the wireless sensors used for wind turbine blade structural monitoring.
