A pleat counter and methods are provided to accurately count the number of pleats in a corrugated sheet of material to be used for the production of air filters. The pleat counter comprises a pleat detector mounted underneath a mounting board for counting the pleats. The mounting board is configured to position the pleat detector adjacent to the corrugated sheet of filter material. The pleat detector includes one or more sensors configured to detect the presence of individual pleats comprising the corrugated sheet. The pleat counter includes an interface configured to enable coupling the pleat counter with a data processing system. The data processing system may comprise any of a desktop, a tablet, a server, a mobile phone, a media player, a personal digital assistant (PDA), a personal communicator, a network router or hub, a wireless access point (AP) or repeater, a set-top box, or a combination thereof.

A spill resistant beverage container assembly for spill free beverage consumption includes a cup and a lid that is complementary to a top of the cup so that the lid is positioned to be selectively coupled to the cup to sealably close the top. The lid comprises a sidewall that is coupled to and extends between an upper plate and a lower plate to define an interior space. An aperture is positioned in the lid proximate to a circumference of the lid. A detection and access module that is coupled to the lid and positioned in the interior space is configured to detect motion in proximity to the aperture, positioning the detection and access module to open the aperture so that the aperture is configured to allow sipping of a beverage that is positioned in the cup.

A rotational angle sensor includes a stator element and rotor element. The stator element has a stator transmitting coil and stator receiving coil. The rotor element is rotatably mounted about a rotation axis, relative to the stator element, and has a rotor receiving coil and rotor transmitting coil electrically connected to each other. The rotor receiving coil is inductively coupled to the stator transmitting coil such that an electromagnetic field produced by the stator transmitting coil induces a current in the rotor receiving coil that flows through the rotor transmitting coil and causes the rotor transmitting coil to produce a further electromagnetic field. The stator receiving coil is inductively coupled to the rotor transmitting coil such that the inductive coupling between the stator receiving coil and the rotor transmitting coil is configured with reference to a rotational angle between the stator element and the rotor element, and such that the further electromagnetic field induces an angle-dependent alternating voltage in the stator receiving coil. The stator transmitting coil has a first circular outer partial winding, and a first circular inner partial winding positioned within and electrically connected to the first outer partial winding such that the first inner partial winding has an opposite current flow with respect to the first outer partial winding. The rotor receiving coil has a second circular outer partial winding and a second circular inner partial winding positioned within and electrically connected to the second outer winding such that the second inner winding has an opposite current flow with respect to the second outer partial winding. The first and second outer partial windings, and the first and second inner partial windings are oriented with respect to each other, respectively.

A rotary machine for the treatment of containers is described. This rotary machine comprises a stationary underframe, a rotatable container table for receiving the containers, a motor designed as an internal rotor for direct drive of the container table, a bearing for supporting the container table and/or a non-rotatably connected supporting structure on the underframe radially outside the motor, and a rotary encoder for determining the rotational position of the container table. By positioning the rotary encoder radially outside the motor, the accuracy of the rotary position determination can be improved, especially for rotary machines with comparatively large pitch diameters and the accessibility of the rotary encoder for maintenance measures.
