Time-of-flight augmented structured light range-sensor
The technology described herein is a depth camera that uses structured light and modulated light to produce a depth image. The modulated and structured light allows a time-of-flight depth to be calculated for each unit (e.g., a single dot) of the reflected structured light image captured by the depth camera's image sensor. The time-of-flight depth can be used to accurately identify each unit of the reflected structured light image. Once each unit of the reflected structured light image is identified, a structured light triangulation algorithm can be used to calculate a depth for each unit of the reflected structured light image. The present technology also allows a confidence score to be generated for the assigned depths within the depth image by comparing the structured light depth for each unit to the TOF depth for each unit. |

Bobbin carrier for a braiding, winding or spiraling machine
The invention relates to a bobbin carrier for receiving a bobbin which is set up for unwinding a strand material, wherein the bobbin carrier is provided for use in a braiding, winding or spiraling machine and is set up to rotate relative to the machine during operation of the latter. The bobbin carrier has a tensile-force measuring device for measuring the tensile force of the strand material unwound from the bobbin and has a first data transfer device for transferring data. According to the invention, the first data transfer device is set up to transfer measured tensile force values to a second data transfer device arranged outside the bobbin carrier. As a result, too low or too high tensile forces in the strand material can be detected early at the individual bobbin carriers. The tensile force can be kept largely constant by the transfer of set point tensile force values from the second data transfer device to the first data transfer device and by a suitable control or regulation device at the bobbin carrier. |

Knitting mechanism for circular knitting machine and the circular knitting machine
Provided is a knitting method and a knitting mechanism, and a circular knitting machine, in which in jacquard or semi jacquard knitting using a circular knitting machine, welt stitching is avoided so as to prevent the breakage and overlapping of yarns and filaments. According to the present invention, only needles selected for knitting and needles selected for tucking perform stitching, and needles selected for welting are prevented from performing stitching by a deactivation method, and thus the needles selected for welting do not perform stitching, so that the load on old loops can be suppressed, and breakage and overlapping of yarns and filaments can be prevented. |
