The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass.

An apparatus is provided comprising a detector, a memory, and a logic component. The detector is configured to receive a rotary motion input signal and a counter signal and to send a plurality of time values based on the input signal and the counter signal. The memory stores the plurality of time values in an ordered sequence and is coupled to the detector. The logic component selects time values stored in the memory by skipping a predefined number of time values in the ordered sequence, reads the selected time values to determine a coherent set of data values, and sends the coherent set of data values.
