Abstract: A twine knotter (10) for forming two knots (16, 33) in a pair of twine strands comprising: a drive pulley (20), a bill hook (9) rotatably driven by the drive pulley (20) about a knotter axis (K) to form two successive knots (16, 33) in the pair of twine strands (5, 7), a twine holding device (18) for clamping the pair of twine strands (5, 7) between a first clamping element (21) and a second clamping element (22), and a twine knife (13) for cutting the pair of twine strands (5, 7). The second clamping element is driven rotatably about a twine holder axis (G) by the drive pulley such that the rotatable second clamping element completes two rotations for one rotation of the drive pulley, and the twine holder axis (G) and the knotter axis (K) enclose an angle of less than 45° with one another.

Abstract: A secure computing device having a storage arrangement configured to store a secret. The secure computing device includes a first interface configured to control a display, and a second interface configured to receive an input signal having information which reproduces a prompt to display the secret. The secure computing device is designed to read the secret from the storage arrangement on the basis of the input signal, and to control the display via the first interface in such a way that a display of the secret is effected.

Abstract: A method comprises generating a signed blockchain transaction using a secure computing device arranged in a local area, and an apparatus set up for short-range communication. The method comprises associating the signed blockchain transactions with the local area, wherein the signed blockchain transaction indicates a presence of the apparatus in the local area.

Abstract: An electronic apparatus having a memory arrangement, which is configured to store a plurality of sets of private-key material, and a data processor, which is configured to sign a message in accordance with two or more sets of private-key material from the plurality of sets of private-key material.
