    摘要： Method and apparatus for forming an annular composite structure is provided. The apparatus includes an annular shaped tool and a forming head. The annular shaped tool includes a forming surface of a select cross-sectional geometry. The forming head is configured to form continuous ply layers one ply at a time circumferentially about the forming surface of the tool.
    The method comprises steps of applying continuous ply layers one at time on a forming surface of an annular tool that has a select cross-sectional geometry; and forming the ply layers on the full circumference annular tool with a forming head.

    摘要： A spin sensor (300) and method of detecting fuze spin are disclosed. The spin sensor (300) includes a fuze housing (220) , a sense weight (390) and a rotating induction device (310). The rotating induction device (310) comprises a first rotatable element affixed to the fuze housing (220) and a second rotatable element affixed to the sense weight. The second rotatable element is mechanically coupled to the first rotatable element such that it may rotate relative to the first rotatable element. In addition, the second rotatable element is inductively coupled to the first rotatable element such that the relative rotation between the first rotatable element and the second rotatable element generates a spin signal on an electrical connection to the rotating induction device (310). The spin signal may be compared to a suitable spin profile to determine if a valid spin environment is present.

    摘要： The present invention comprises a device for determining the roll orientation of a body with respect to a local fixed coordinate system or a predetermined reference vector The device uses a measurement of an external magnetic field, such as the Earth's magnetic field, to determine a roll orientation reference with respect to the field or an uncompensated roll orientation The uncompensated roll orientation is then adjusted according to a bias angle, such as an angular difference between the external magnetic field and a local fixed coordinate system, to determine the roll orientation of the device with respect to the local fixed coordinate system or a compensated roll angle.
