Transmitter module for use in a modular power transmitting system

Abstract: A modular power transmitting system comprises multiple transmitter modules being connected together for transmitting power inductively to a receiver. The transmitter module is connected with other transmitter modules for transmitting power inductively to the receiver, wherein the transmitter module (40) comprises at least one transmitter cell (30), each transmitter cell having one transmitter coil (33) by which the transmitter cell transmitting power to the receiver, the transmitter module having an outer periphery (45) being shaped so as to fit to neighboring transmitter modules for forming an power transmitting surface, the at least one transmitter cell being arranged such that the power transmitting surface is constituted by an uninterrupted pattern of adjacent transmitter coils extending in said surface, and interconnection units (110,111) for connecting with neighboring transmitter modules for sharing a power supply.

Dielectric resonator antenna

Abstract: A dielectric resonator antenna has a dielectric layer and a conducting layer formed on a main surface of the dielectric layer. An electrical contact is formed on the main surface for connecting the dielectric layer to a transmission line for transferring a signal between the dielectric layer and the transmission line. The electrical contact is insulated from the conducting layer. A conducting strip is connected to the electrical contact and is on a side surface of the dielectric layer. The side surface is not on the same plane of the main surface. Rather, the side surface is perpendicular to the main surface of the dielectric layer.

Thermo‐Mechanical Responses of Liquid‐Crystal Networks with a Splayed Molecular Organization

Abstract: Films of liquid-crystal networks with a splayed molecular alignment over their cross-section display a well-controlled deformation as a function of temperature. The deformation can be explained in terms of differences in thermal expansion depending on the average molecular orientation of the mesogenic centers of the monomeric units. The thermal expansion of the anisotropic polymers has been characterized as a function of their molecular structure and the polymerization conditions. As a reference, films with an in-plane 90° twist have also been studied and compared with the splayed, out-of-plane molecular rotation. The twisted films show a complex macroscopic deformation owing to the formation of saddle-like geometries, whereas the deformation of the splayed structured is smooth and well controlled. The deformation behavior is anticipated to be of relevance for polymer-based microelectromechanical system (MEMS) technology.
