    摘要: A system of an embodiment of the invention includes an array of micro-electromechanical (MEM) device assemblies and a testing mechanism situated outside of the array of the MEM device assemblies. Each MEM device assembly includes a MEM device capable of being individually written to, but incapable of being electrically read. The testing mechanism tests each MEM device assembly for proper operation without directly reading the MEM device of the MEM device assembly.

    摘要: A printhead apparatus, an inkjet printer system, and a method of built-in test employ a test flag transmitted through a data channel of a printhead. The apparatus includes a plurality of printheads, a data register at each printhead, and a status channel. Each printhead has a unidirectional data channel (UDC) to provide data to the printhead. The data register detects proper reception of a test flag received by the printhead through the UDC. The status channel reports printhead status information including whether or not proper reception of the test flag was detected by the data register. The system includes the apparatus and a controller to generate the test flag and receive the printhead status information. The method includes sending a test flag, and verifying proper reception thereof.

    摘要: A charge control circuit for controlling a micro-electromechanical system (MEMS) device having variable capacitor formed by first conductive plate and a second conductive plate separated by a variable gap distance. The charge control circuit comprises a switch circuit configured to receive a reference voltage having a selected voltage level and configured to respond to an enable signal having a duration at least as long as an electrical time constant constant of the MEMS device, but shorter than a mechanical time constant of the MEMS device, to apply the selected voltage level across the first and second plates for the duration to thereby cause a stored charge having a desired magnitude to accumulate on the variable capacitor, wherein the variable gap distance is a function of the magnitude of the stored charge.
