Abstract: The ballistocardiography device (200) comprises: a non-homogeneous and anisotropic support (105) having a portion forming a stress or deformation guide (205) and a portion transmitting fewer stresses or deformations in the frequency range between 0.05 Hz and 25 Hz, and at least one sensor (210) of a signal representing at least one movement and/or variation of quasi-static stress of the guide in the frequency range between 0.05 Hz and 25 Hz, positioned facing the stress or deformation guide. The stress or deformation guide is on the surface.

Abstract: A simplified computer device is provided and may be used by persons having memory loss to connect via a network, such as the Internet, to one or more other computer devices. The simplified computer device is operable to obtain image, text and/or audio files from the other computer device for displaying on a display screen or for playing on an audio player, as the case may be, of the simplified computer devices to assist the persons with memory loss in recalling the identity and/or other information about their family members, friends, caregivers, and other acquaintances. Using a limited set of buttons on the simplified computer devices, the persons having memory loss can automatically link to one or more predetermined other computer devices and retrieve the image files and associated text and audio files.

Abstract: A write head for an X-Y plotter comprises a write head body (10) movably mounted in a horizontal direction relative to a write medium (14) and a pen (30) movably mounted in a vertical direction with respect to the head body (10) between pen-up and pen-down positions. The mounting for the pen (30) allows movement with respect to the head body and (10) comprises a parallelogram-shaped deformable element (20) made out of molded plastic material. This deformable element has a first side portion (21) attached to the head body, a second side portion (22) supporting the pen and two parallel arms (23, 24) pivotally linking the first and second side portions through horizontal hinge portions of reduced thickness (23a, 23b, 24a, 24b). An actuator (40) has a permanent magnet (44) fixed to the head body and a coil (42) fixed to the second side portion and moves the pen between pen-up and pen-down positions.

Abstract: The structural base unit of the machine is made of a one-piece shaped beam (40) which extends along a first direction (Y) with a first portion (41) which, due to its own stiffness, supports and guides the carriage (12) carrying the writing head (11) along its translational motion in the first direction (Y), and with second and third portions (45) which defines supporting surfaces for the drum (20) driving the printing medium in a second direction (X) perpendicular to the first direction (Y). Guiding of the carriage (12) is ensured by rails (43, 44) formed integral with the beam or attached to it, and a slot (50) cut in the shaped beam (40) along the action area of the writing head for providing a passage for the printing medium and its engagement with the drum (20).
