| Feedback-based systems and methods for bending wire are provided. The systems and methods may allow for modification of wire bending based on feedback received from one or more feedback-generating elements (e.g., image-capturing device(s), computer processing device(s), vision systems, etc.) used for monitoring one or more characteristics of a wire (e.g., shape, size, dimension, angular configuration, etc.) to determine, and provide to various wire-bending components of the system, appropriate modifications to the wire-bending process. Modifications to the wire-bending process may occur in real time without stopping the wire-bending process. Furthermore, a wire may be bent into a sinusoidal wire structure for forming springs for use in various applications. | ||||||
| 223 | Multi-strand electrode and method of making | US14250509 | 2014-04-11 | US09546429B1 | 2017-01-17 | Matthew Dion |
| An electrode having a plurality of connected strands retained by a current collector is described. A connected strand has first and second ends that are retained by a current collector, and may be retained at different locations along the length of the current collector. A connected strand retained by the current collector in substantially the same location along the current collector, is a looped strand. A connected strand provides two paths for current to move through the strand to the current collector and may therefore provide lower resistance than a free strand having only one end coupled to the current collector. Furthermore, a connected may move less as a function of fluid forces and retain more bio-film in turbulent conditions than free strands. Finally, a connected strand has no free extended end and therefore is less likely to puncture through an ion conductive membrane. | ||||||

| A reinforcement strip is laid on a rotating receiving surface during the manufacture of a tire. The strip passes through a guide which is moved alternatingly transversely relative to a travel path of the strip, whereby the strip is laid in an undulating pattern on the receiving surface. The amplitude of the alternating transverse movement is varied as a function of a ratio of: (a) the speed of a portion of the strip approaching the guide, and (b) the speed of the receiving surface. Between the guide and the receiving surface the strip is pivoted by 90 degrees about the strip's longitudinal axis so as to be laid tangentially on the receiving surface. | ||||||
