    • Embodiments of the present invention address deficiencies of the art in respect to securing extranet access to a collaborative environment and provide a method, system and computer program product for secure extranet access to collaborative activities in a collaborative environment. In an embodiment of the invention, a method for secure extranet access to collaborative activities in a collaborative environment can be provided. The method can include adding an extranet collaborator to a collaborative space within a collaborative environment and establishing encryption credentials for the extranet collaborator. Thereafter, in response to detecting a change to the collaborative space, the change can be encrypted with the credentials and the change can be messaged to the extranet collaborator. Notably, a contribution to the activity can be received from the extranet collaborator. Once received, the contribution can be decrypted with the credentials and the contribution can be posted to the activity.

    • Magnetic wave generator and use. The wave generator includes a driver portion with motor and rotating mount with a first magnet; and an actuator portion that includes a pivot mount and a pivoting arm coupled thereto, with a second magnet at one position on the pivoting arm, and a buoyant float member at another. During operation, the actuator portion is at least partially submerged in a fluid of a wave tank, with the driver portion just outside the wave tank. The driver portion rotates the rotating mount, repeatedly moving the first magnet near then away from the actuator portion. Accordingly, the pivot arm rotates away due to magnetic repulsion, pushing the float member down into the fluid, then buoyancy of the float member provides a restorative force that rotates the pivoting arm, allowing the float member to rise. The movement of the float member induces waves in the wave tank.
    • 磁波发生器和使用。 波发生器包括具有马达的驱动器部分和具有第一磁体的旋转安装件; 以及致动器部分,其包括枢转安装件和与其连接的枢转臂,在枢转臂上的一个位置具有第二磁体,在另一个位置具有浮力浮子部件。 在操作期间,致动器部分至少部分地浸没在波箱的流体中,其中驱动器部分恰好在波箱外部。 驱动器部分旋转旋转座,重复地移动第一磁体,然后远离致动器部分。 因此,枢转臂由于磁力排斥而旋转离开,将浮动构件向下推入流体中,然后浮子构件的浮力提供使旋转臂旋转的恢复力,允许浮子构件升高。 浮子构件的运动在波浪箱中引起波浪。

    • Magnetic linear actuator (MLA) and use. The MLA includes a driver portion with motor and rotating mount with a first magnet (M1) having poles aligned in a plane, and an actuator portion, having a frame with a second magnet (M2) proximate to a first end of the frame with a specified pole facing the frame's center, and a third magnet (M3) proximate to a second end of the frame with the specified pole facing the frame's center. The frame holds M2 and M3 collinear with M1, in the plane, and on opposite sides of the M1, and is constrained to move along an axis collinear with M1, M2, and M3. During operation, the motor rotates M1 through a first orientation where M1 attracts M2 and repels M3, then a second orientation where M1 repels M2 and attracts M3, in response to which the frame moves back and forth, e.g., reciprocates.
    • 磁线性致动器(MLA)和使用。 MLA包括具有马达和旋转安装座的驱动器部分,其具有在平面中对齐的极的第一磁体(M1)和致动器部分,具有框架,邻近框架的第一端附近具有第二磁体(M2) 指定的杆面对框架的中心,以及靠近框架的第二端的第三磁体(M3),其中指定的极面对框架的中心。 该框架保持M2和M3在M1的平面和M1的相对侧与M1共线,并且被限制为沿着与M1,M2和M3共线的轴移动。 在操作期间,马达通过M1的第一方向旋转M1,M1的第一方向吸引M2并排斥M3,然后是第二方向,其中M1排斥M2并吸引M3,响应于此,框架来回移动,例如往复运动。

    • The present invention is an improved grain drill and a method retrofitting a previously manufactured grain drill to provide accurate weight determination of seed in a seed hopper of the grain drill. A grain drill in accordance with the invention includes a frame having a plurality of wheels for supporting the grain drill during rolling over a surface of ground to be planted with seed grain; a hopper for containing the seed grain to be planted in the ground; a support which is joined to opposed sides of the frame and to spaced apart locations of the hopper to transfer weight of the hopper to the frame, the support including at least one weight sensing device which senses a weight of seed grain in the hopper transferred through the support to the frame and provides an output of the sensed weight of the seed grain in the hopper; and a display, coupled to the output, for displaying the weight of the seed grain contained in the hopper.
