Abstract: Assembly systems and methods are provided for elastically deforming a non-circularly shaped washer while driving the washer through an insertion tool into a workpiece, such as a pressure sensor, having a correspondingly shaped recess with an inner wall diameter less than a maximum radial dimension of the non-circular washer. The washer is released from radial compression into the recess so as to permit the washer to become fixated against the inner wall of the recess by a retention force. The fixated washer has a height greater than a height of the recess inner wall, and may serve as a deformable sealing element between the workpiece and other components.

Abstract: This disclosure provides systems, methods and apparatus for OLED control circuits. In some implementations, the OLED control circuit can be configured to reverse the bias of the OLED without the use of a dedicated initialization voltage. A low voltage data signal applied on a data line can be used to drain voltage from the anode of the OLED through a diode-connected transistor. A high voltage data signal applied on the same data line can be used to store a reference voltage on a storage capacitor, where the reference voltage is also a function of the threshold voltage of a driving transistor of the OLED control circuit. The stored reference voltage can be used to compensate for the threshold voltage of the driving transistor when the OLED is energized by a current, so that the current is independent of the threshold voltage of the driving transistor.
