Abstract: An apparatus yields signals that are equivalent to ECG signals and allow determination of a heartbeat interval or heart rate from bio-vibration signals including vibrations derived from heartbeats. An ECG meter acquires ECG signals of a sample, and a piezoelectric sensor acquires bio-vibration signals of the sample simultaneously. The bio-vibration signals include beating vibration signals derived from heartbeats. A learning unit of a prediction modeling apparatus establishes a prediction model by machine learning in which ECG signals are used as teaching data, and model input signals obtained by performing a specified processing on the bio-vibration signals are input. The learning unit delivers the prediction model to a prediction unit of a signal processing apparatus. The prediction model predicts and outputs pECG signals upon input of model input signals obtained by performing a specified processing on bio-vibration signals acquired from a subject under prediction with a piezoelectric sensor.

Abstract: The present invention provides an imaging apparatus, comprising a multifocal lens (210) having a plurality of lens portions different from one another in focal length; an imaging device (29) for converting an image formed thereon by said multifocal lens (210) into an electric signal to be outputted therethrough as an image signal; a computing unit (33) for carrying out a weighted computing process on said image signal from said imaging device (29) in accordance with a predetermined compensation function to output a compensated image signal as an output image signal, and in which said compensation function is an inverse function obtained based on a point spread function with respect to an object disposed at a predetermined distance from an optical system constituted by said multifocal lens (210).

Abstract: An imaging apparatus for imaging a first object at a normal distance and a second object nearer than the first object readily with high precision. The imaging apparatus has an imaging lens, an imaging device for capturing an image formed by the imaging lens, and a camera control unit. The imaging lens is a multifocal lens and contains a first lens portion having a first focal length for imaging the first object (e.g., the user of the imaging apparatus) at a normal distance and a second lens portion having a second focal length for imaging the second object (e.g., a bar code) nearer than the first object. The first and second lens portions are arranged on the same plane and formed in one piece. The information collected by imaging the second object is used for processing such as communications or displays.

Abstract: A processing apparatus includes a processing chamber and an insertion jig for inserting an object to be processed into the processing chamber. The processing chamber and the insertion jig are adapted to be individually movable relative to a heating section, so that the operation of loading and unloading the object into and from the processing chamber effected by the insertion jig is conducted outside the heating section, thereby preventing the outside air from being induced to enter the heated processing chamber, together with the object of the processing, and thus avoiding the occurrence of various problems, for example, the object of processing being disorderly oxidized by the oxygen contained in the outside air, and the foreign matter contained in the outside air being undesirably attached to the surface of the object, so as to obtain excellent processing results.
