A z-axis-tolerant inductive power transfer system using a bipolar double d receiver coil structure
Jure Domajnko, Nataša Prosen, 2023, izvirni znanstveni članek

Opis: This paper presents a solution to a limitation of wireless power transfer that arises when using two D-shaped transmitter and receiver coils. Double D, or DD, coils are well known to have a polar, directional magnetic field, which increases the misalignment tolerance in one of the directions. The misalignment tolerance is nonsymmetric, and it is significantly better in one of the directions, which can also be considered a shortcoming. An additional shortcoming of the DD coil is that it is dependent on the rotation around the z-axis, due to the directional magnetic field. This is not a problem when using classic planar spiral coils, which do not generate a directional magnetic field. Therefore, DD coils are not suitable for applications in which the z-axis orientation is not determined and fixed to specific angle and direction. This paper presents a unique design of a transmitter coil, based on a double DD coil. The transmitter coil consists of two DD coils which are perpendicular to each other. The proposed transmitter structure can excite the receiver DD coil in a way that the efficiency of the power transfer is the highest, regardless of the orientation. The proposed transmitter structure can, therefore, solve the problem with rotation of a single DD coil. The proposed system structure was tested on the small-scale experimental setup

Fiber-optic sensors for measurements of torsion, twist and rotation : a review
Vedran Budinski, Denis Đonlagić, 2017, pregledni znanstveni članek

Opis: Optical measurement of mechanical parameters is gaining significant commercial interest in different industry sectors. Torsion, twist and rotation are among the very frequently measured mechanical parameters. Recently, twist/torsion/rotation sensors have become a topic of intense fiber-optic sensor research. Various sensing concepts have been reported. Many of those have different properties and performances, and many of them still need to be proven in out-of-the laboratory use. This paper provides an overview of basic approaches and a review of current state-of-the-art in fiber optic sensors for measurements of torsion, twist and/or rotation.

Spatial rotation and recognizing emotions : gender related differences in brain activity
Norbert Jaušovec, Ksenija Jaušovec, 2008, izvirni znanstveni članek

Opis: In three experiments, gender and ability (performance and emotional intelligence) related differences in brain activity - assessed with EEG methodology - while respondents were solving a spatial rotation tasks and identifying emotions in faces were investigated. The most robust gender related difference in brain activity was observed in the lower-2 alpha band. Males and females displayed an inverse IQ-activation relationship in just that domain in which they usually perform better: females in the emotional intelligence domain, and males in the visuospatial ability domain. A similar pattern of brain activity could also be observed for the male/female respondents with different levels of performance and emotional IQ. It was suggested that high ability representatives of both genders to some extent compensate for their inferior problem solving skills (males in emotional tasks and females in spatial rotation tasks) by increasing their level of attention.
