    摘要: A satellite having a longitudinally elongated body and being capable of operating in the thermosphere. The satellite can be powered by an electric rocket engine, and includes a remote sensing system configured to obtain images of Earth. An elongated axis about which the elongated body extends can be generally aligned with a forward direction of the satellite, with a viewing angle from the satellite oriented transverse to the elongated axis. A center of mass of the satellite can be forward of a center of drag to produce positive natural stability. The remote sensing system, which can be part of a payload, can include a movable mirror and one or more movable optical elements. A first mirror can be pivoted, and/or other optical elements, including the payload, can be rotated about the axis of the elongated body. Counter-acting masses can be used to null motion of the movable components.

    摘要: La presente invención se refiere a un mecanismo de liberación compacto para nanosatélite que tiene la finalidad de sostener una masa de prueba (esfera), dentro de una cámara donde se realiza un experimento. La masa de prueba se sostiene por medio de dos paredes móviles, que pertenecen a la cara superior e inferior de la cámara, las cuales se mueven al mismo tiempo en direcciones opuestas para sostener y posicionar a la esfera en el centro de la cámara en todo momento. El mecanismo consiste en dos tornillos de avance que giran en sentidos contrarios uno del otro gracias a un motor DC y a un sistema de engranajes. Estos tornillos de avance están enroscados a las paredes superior e inferior de la cámara, por lo que su rotación resulta en el desplazamiento traslacional y simultáneo de las paredes en sentidos opuestos para comprimir y liberar a la esfera.

    摘要: The embodiments of the present disclosure are capable of capturing a user's movement using inertial measurement units (IMUs) that are embedded in, or otherwise attached to, clothing. In one embodiment, a wearable system for capturing a user's bodily movements includes a wearable item mechanically coupled to an inertial measurement unit (IMU). The wearable item, when worn by a user, positions the IMU proximate to a body part of the user. The system further includes a processor communicatively coupled to the IMU and configured to receive the sensor data from the IMU, generate movement data based on the sensor data, and transmit the movement data to a device. The device includes a processor configured to receive the movement data, generate a kinematic chain model of the user, the model representing positions and orientations of one or more joints of the user at a given time, modify the kinematic chain model based on the movement data, determine a force experienced at a joint of the user using the kinematic chain model, and record the kinematic chain model and the force over a period of time.

    摘要: Method to verify if a vibrational event has a higher intensity than a predefined intensity threshold Th1, which is linked to a predefined frequency ThF, preferably in order to consider/classify the vibrational event as dangerous/risky, said method is characterized by the fact that: - the data detected by at least one accelerometer (102) are acquired along two axes, respectively X axis and Y axis, which are perpendicular to each other, - the values of frequency F and intensity I of at least one portion of the signals, derived from the acceleration data thus acquired along the two axes X and Y, are determined when they exceed a threshold of predefined intensity Th2, - on the basis of the frequency F thus determined, a predefined intensity threshold Th1 is identified, - it is checked whether the intensity I thus determined is higher or lower than the predefined intensity threshold Th1 thus identified, to establish whether or not the vibrational event from which said signals were derived has an intensity greater than said threshold of predefined intensity Th1 thus identified.
