Abstract: A semiconductor package includes multiple dies that share the same package pin. An output enable register provided on each die is used to select the die that drives an output to the shared pin. A hardware arbitration circuit ensures that two or more dies do not drive an output to the shared pin at the same time.

Abstract: Disclosed herein are a toothbrush and method of manufacturing the same, wherein the toothbrush comprises an arced tray comprising a base and sidewalls defining a length of the arced tray, a first longitudinal edge of each sidewall perpendicularly coupled to opposing longitudinal edges of the base to define a channel between the sidewalls, the channel adapted to receive teeth therein. The toothbrush further includes flexible flanges perpendicularly coupled to corresponding second longitudinal edges of each of the corresponding sidewalls opposite the corresponding first longitudinal edges, the flanges extending over a portion of the channel, a first end of the channel having a first width smaller than a second width at a second end of the channel. The toothbrush also includes a handle coupled to a side of the arced tray opposite the channel and extending therefrom, the curvature of the arced tray curving away from the handle.
