Abstract: An inductive absolute position sensor has a scale with planar conducting features on a pattern repeating every spatial period TC along a measuring path and a reading head with planar windings: multipolar sine and cosine sense windings of spatial period TF=TC/M, M an integer, a unipolar first drive winding surrounding the sense windings and a multipolar second drive winding of spatial period TC/N along the measuring path, with N=M±1. An electronic circuit makes a first mode measurement using the first drive winding and a second mode measurement using the second drive winding. The absolute position in a range TC is computed from both modes' measurements. The sensor may be as compact as the incremental sensor it replaces, as the scale pattern and second drive winding needed for making it absolute do not need extra space.

Abstract: The invention relates to a biomaterial and/or a biocomposite based on sunflower seed shells/husks. According to the invention, it is proposed that sunflower seed shells/husks are used instead of wood, bamboo or other wood-like fiber products as the original material for the biocomposite products and are used for the production of such products in order to improve the previous biomaterials, and in particular also to design said materials for improved cost efficiency and to improve their material properties.

Abstract: A process for producing a biomaterial product based on sunflower seed hulls/sunflower seed husks comprising providing or producing a sunflower plastic compound (SPC) compounded material (SPC PBS, SPC PBSA), wherein the material is obtained by compounding a sunflower seed hull material/sunflower seed husk material with a biodegradable plastic, for example polybutylene succinate (PBS), polybutylene succinate-adipate (PBSA), or the like. The SPC compounded material is preferably used for producing an injection molded product, for example biodegradable containers, packagings, films or the like, in particular coffee capsules, tea capsules, urns, cups, plant pots, flowerpots, or the like.

Abstract: A capacitive imaging method or device using an array of row electrodes 101 and column electrodes 102 on a substrate 100, wherein cross-capacitance between row and column electrodes is obtained from row electrode 101 self-capacitance measured with the remaining electrodes grounded, column electrode 102 self-capacitance measured with the remaining electrodes grounded, and combined row and column electrode self-capacitance measured with the remaining electrodes grounded. A preferred embodiment is a hand-held wall scanner for detecting hidden features having a two-dimensional display the size of the array and located over it. Hidden features influencing row-to-column cross-capacitances are thus imaged in real size and at their real location.
