Abstract: A manual device opening and closing a lock of a door or window has a control rod; a supporting body having a cavity for the control rod; a manual gripping member having a housing; and an adapter interconnecting the gripping member and the supporting body. The adapter arranged in the housing provided in said gripping member and in turn having a housing for the supporting body. An elastic axial extraction block of the supporting body from the control rod. A block between the adapter element and the supporting body and between the adapter element and the manual gripping member. A supporting plate of the supporting body fixed to the door or window and has a hole for an end of the supporting body to rotatably engage and extends outside the adapter element. A braking and stabilizing member for inserting of the control rod in the cavity of the supporting body.

Abstract: The manual control device to open and close the lock of a door or window has a support body having a longitudinal cavity; a rotatable manual gripping member having a housing; a control rod engaged in the cavity of the support body; at least one quick blocking element of the axial extraction of the support body from the control rod, the support body having an end in the manual gripping member rigidly engaged in the housing and an end external of the gripping member. A support plate of the support body fixable to the door or window and having a hole to rotatably engage the external end of the support body. An angular position indexer of the manual gripping member, the indexer having a blocking seat and a one snap-fitting member engaged in the blocking seat, the blocking seat or snap-fitting member being formed integrally with the support body.

Abstract: A data receiver is arranged to receive data comprising a sync word having a predetermined data frequency (f.sub.tx) and predetermined value. A clock signal (SCLK) is generated which is substantially synchronised with the received data. The n clocks (CLK1-CLK8) are generated, each of the n clocks having a frequency (fclk) which is substantially the predetermined data frequency (f.sub.tx) and is out of phase with an adjacent clock of the n clocks by 1/n of a clock period. The sync word is sampled using each of the n clocks to determine which one of the n clocks is optimally synchronised with the sync word and to provide the determined one of the n clocks at an output (18). The determined one of the n clocks provides the clock signal (SCLK).
