Automated systems and methods of using an end-effector mounted on a robot arm to remove a tape from an object surface are provided. The end-effector includes a gripping mechanism and a force sensor, which is instructed by a controller to automatically detect the peeling state and adjust its peeling parameters to optimize the removal while the end-effector moves along the object surface to remove the tape.
A cultivation system (100) includes a substantially vertical film (10) including a distribution of holes (12) each to receive a basket (50). A mounting mechanism (20) is disposed adjacent to a top edge of the vertical film. The system allows for a customized distribution of the holes and thus allows for the control of the spacing between the received baskets. The vertical film further includes water-guiding features (e.g., channels) to flow fluid primarily by gravity and direct the fluid to the holes.
A light control film includes a two-dimensional array of projections arranged across the light control film. A square of a magnitude of a Fourier transform frequency spectrum of the projections includes an annular continuous peak and a corresponding annular continuous full width (FW) at 15% maximum. The peak and the FW vary by no more than about respective factors of 10 and 3 along the annular continuous peak.
Sensored bushing (1) for medium or high voltages, the bushing comprising a) a bushing body (140); b) an elongated bushing conductor (560); c) a tubular sensing electrode (170), arranged coaxially around the bushing conductor, so that the sensing electrode and the bushing conductor are operable as electrodes of a primary capacitor of a voltage divider for sensing the voltage of the bushing conductor; d) a tubular shield electrode (190), arranged coaxially around the sensing electrode (170); e) a spacer (200), arranged radially between the sensing electrode (170) and the shield electrode (190) and mechanically connected to the sensing electrode and to the shield electrode to maintain the sensing electrode and the shield electrode in a fixed spatial relation to each other.
The present disclosure provides an apparatus (2, 4) for dispensing adhesive. In one embodiment, the apparatus comprises: a housing body (12) including a cavity and an aperture (22), wherein the housing body includes a front plate (20) having an angled internal surface (24); an internal member having an angled surface; a channel (226) for adhesive positioned to extrude adhesive between the angled internal surface and the angled surface of the internal member onto the outer surface of the selected male pipe.
