Abstract: A stress sensor includes two capacitor plates held in a spaced-apart relationship by a connector block situated therebetween. The connector block includes a plurality of rods protruding from opposite connector block sides and extending into a respective capacitor plate to attach peripheral portions of each capacitor plate to the connector block. A small air gap is maintained between peripheral portions of the capacitor plates by the inclusion of a spacer member. Terminal end portions of the protruding rods are deformed such as by the application of heat over an outer surface of the capacitor plates to retain the capacitor plates in a fixed mutual relationship. The terminal end portions of the rods further serve to prevent horizontal or vertical slippage between the capacitor plates when the sensor is vulcanized into rubber compounds such as in a tire.

Abstract: A playyard system includes a playyard structure and a canopy. The playyard structure is partially covered by the canopy which channels heat outward to provide improve shading and ventilation. Sides of the playyard structure have mesh panels with removable covers to further control shading and ventilation. Accordingly, the playyard system has improved thermal characteristics. Furthermore, the canopy allows visibility and easy access to the interior of the playyard structure.
