  • DEVICE FOR DIVIDING AN ANGLE INTO A PLURALITY OF SMALLER EQUAL ANGLES
    Publication number: 20210309043
    Abstract: A device for dividing an angle into a plurality of smaller equal angles, comprising: a lower translucent sheet; and an upper translucent sheet positioned over the lower translucent sheet and pivotally connected to the lower translucent sheet at a pivot point for alignment to a vertex of the angle, to enable the upper translucent sheet to rotate relative to the lower translucent sheet; wherein the translucent sheets are marked with visual indicia corresponding to: a straight arm line for alignment on an arm of the angle; and a plurality of progressive loci curves using a T-tool defined by a straight line (EF) of a fixed length between two points (E, F) that is bisected by a bisecting straight line (B) at 90 degrees.

  • Data networks
    Patent number: 7388867
    Abstract: A data network in which at least one switch is provided with the facility for estimating current network demands using a polygonal approximation to scaled cumulant generating function. The approximation is iteratively refined in accordance with sampled data passing through the switch. The switch estimates the demand associated with a new data processing request as it is received by the switch and decides whether to accept the request based on available resources.
