A pressure sensor comprising: a base film on which a conductor pattern having one or more electrodes is formed; a cover film laminated on the base film so as to cover the electrodes of the conductor pattern; and a spacer disposed between the cover film and the base film so as to form a hollow portion having a predetermined gap between the electrode and the cover film; wherein a portion corresponding to the hollow portion of the cover film is constructed such that it has a pressure sensing part which is able to deform in a direction to move toward and away from the electrode in accordance with pressure, and of which contact resistance changes in accordance with a contact pressure thereof with the electrode, so that the pressure sensing part detects the pressure by a change of the contact resistance.

An image data processing system has a learning storage apparatus that stores projection matrixes obtained by canonical correlation analysis so as to derive, based on at least one of an image feature and a word feature, a latent variable as an abstract concept used for associating an image with a word corresponding thereto and that further stores information required for obtaining the latent variable acquired by use of the projection matrixes, a probability of occurrence of an arbitrary image feature from a certain latent variable and a probability of occurrence of an arbitrary word feature from a certain latent variable. In this way, a probability of the image feature and word feature being simultaneously outputted can be easily and quickly determined, thereby executing a high-speed annotation or retrieval with high precision.

It is an object of the present invention to provide a measurement system that measures physical quantity distribution over the entire region using a sensor for physical quantity distribution (PQD sensor) that realizes high stretchability, flexibility, etc., in at least a partial region, in order to measure the physical quantity distribution that is regionally distributed in a two-dimensional or three-dimensional manner, as well as a method for measuring physical quantity distribution. Such measurement system comprises: a body for converting physical quantity distribution (PQDc body) structured in such a way that the condition of injection current changes according to the action of the target physical quantity; multiple electrodes arranged in such a way that they can supply injection current to the PQDc body and measure data of the electric potential distribution generated by the PQDc body as a result; a PQD sensor comprising the PQDc body, electrodes, and an electric signal processing unit that processes electrode signals; and a processing part that processes data with the PQD sensor; wherein the measurement method comprises a data acquisition procedure to cause electrodes to generate injection current and measure the electric potential distribution that generates in the PQDc body, which is used as measured data, and an estimation procedure to read the measured data and use the read data to obtain the distribution of the target physical quantity that acts upon the PQDc body.
