    • In a method for making ferroelectric memory cells in a ferroelectric memory device a first electrode comprising at least one metal layer and optionally at least one metal oxide layer is formed on a silicon substrate which has an optional insulating layer of silicon dioxide. A ferroelectric layer consisting of a thin film of ferroelectric polymer is formed on the top of the first electrode layer and at least a second electrode comprising at least one metal layer and at least one metal oxide layer is formed on the ferroelectric layer. The second electrode is deposited by thermal evaporation of a high-purity evaporation source from an effusion cell onto the ferroelectric layer in a vacuum chamber filled with a gas or a gas mixture. A ferroelectric memory device wherein the memory cell has been made with the above method, comprises at least a first and a second set of respectively parallel electrodes (510; 530), wherein the electrodes (510; 530) in a set are provided orthogonally to the electrodes (530; 510) of a nearest following set and with memory cells formed in a ferroelectric layer (520) provided between successive electrode sets, such that memory cells are defined in the crossings between the electrodes (510; 530) which contact the ferroelectric layer (520) on each side thereof.

    • The invention is intended to provide a measuring chair function which will enable the propulsion force applied to a drive ring by the chair user to be measured, and also to provide an electrically operated powerservo on conventional, manually driven wheelchairs. Power or force sensors (2.1) are placed adjacent a respective attachment between drive ring (3) and wheel (4) and function to measure the propulsion force applied on the drive ring by the user. The drive ring is also held by other types of attachment means (2.2) which lack the provision of power or force sensors and which solely provide a force effect in an axial direction and which have the smallest possible effect in the peripheral direction of the drive ring. Each wheel can be substituted for the conventional wheel of a wheelchair and includes quick coupling means to this end. Furthermore, each wheel may be provided with a drive assembly (41) including a motor (64) which can be controlled in response to the measurement signals delivered by the power sensors. A computer unit (56) receives the power signal (55) from each wheel, the wheel speed (57) and also the settings chosen by the user and entered on an instrument panel (8), and calculates useful user information and is effective in controlling the motor in accordance with a variable program, in such instances when the arrangement includes a motor.
