Abstract: In a method for data transmission in which the binary original data (D0, . . . , Dm) is transferred from a transmitter to a unit of a receiver (1), selected preferably by means of a binary base address (A0, . . . , An), preferably to a register (80, . . . , 87), where the original data (D0, . . . , Dm) and preferably also the base address (A0, . . . , An) are transmitted through one or several data lines, the inverted original data (inversion data) (D0′, . . . , Dm′) and preferably also the complementary base address (complementary address) (A0′, . . . , An′, Ak) are transmitted by the transmitter. The transmitted inversion data (D0′, . . . , Dm′) and preferably the transmitted complementary address (A0′, . . . , An′, Ak) are inverted in the receiver, the transmitted base address (A0, . . . , An) and the transmitted original data (D0, . . . , Dm) are compared with the inverted complementary address (A0′, . . .

Abstract: The invention relates to a bat for use in beach tennis, volley tennis and tether tennis or similar games, the bat having a pair of striking surfaces at a distance apart and the space between the striking surfaces including a number of ribs which join the two striking surfaces, the surfaces being preferably of lattice structure and the ribs joining corresponding intersections of the lattices.
