Abstract: A method for detecting error on an input/output (IO) pin of an integrated circuit includes using the input/output pin of the integrated circuit in a first mode by receiving or sending a first value as analog data or digital data. The input/output pin is toggled in a test mode after each instance of using the input/output pin in the first mode. The test mode includes providing a second value disparate from the first value during a set time after using the input/output pin in the first mode, receiving back during the set time a resulting value based on providing the second value, measuring the resulting value, and identifying an error on the input/output pin of the integrated circuit based on the measured resulting value.

Abstract: An apparatus to supply power to at least one gas lamp, the apparatus including a half bridge driver having a striation control circuit which determines an on time (Ton) for a cycle in accordance with a fifty percent duty cycle, the cycle having a plurality of segments and lasting for a predetermined period of time and modulates on times Ton1 and Ton2 of first and second power switches, respectively, of a half-bridge circuit in accordance with a striation control technique for each of the plurality of segments.

Abstract: An apparatus (1100, 2000, 3000) executes an algorithm (2000) to determine a type of lamp (10) that is installed in a lighting unit (1000). The apparatus supplies power to the installed lamp (10) according to a first power control setting that will not overdrive the installed lamp when the installed lamp is of a first lamp type, and that will overdrive the installed lamp when the installed lamp is of a second lamp type. The apparatus (1100, 2000, 3000) detects whether the installed lamp (10) is overdriven at the first power control setting, and uses the detection result to determine the lamp type of the installed lamp (10). The apparatus (1100, 2000, 3000) then supplies power to the installed lamp (10) according to the determined lamp type.
