Abstract: A method of generating in-focus images of measurement locations of a sample holder in a microscopy imaging system is provided. A camera sensor and an array of focusing optics are positioned at a first focal distance from the sample holder. A first image of a measurement location is acquired using the camera sensor. A candidate output image associated with the camera sensor and the array of focusing optics is developed in accordance with the first image. The camera sensor with the array of focusing optics is positioned at a second distance from the sample holder and a second image of the measurement location is acquired using the camera sensor. A portion of the candidate output image is updated in accordance with a portion of the second image in accordance with a selection criterion. The updated candidate image is transmitted.

Abstract: Disclosed examples include synchronous rectifiers and flyback converters, integrated circuits and operating methods, in which a first switch is turned on to allow current to flow for a first time period in a first direction in a transformer primary winding responsive to a first switch voltage transitioning below a first threshold, and a second switch is turned on for a second time period after the first time period to transfer energy from a secondary transformer winding to drive a load. In the same converter cycle, the second switch is again turned on for a third time period in response to a second switch voltage transitioning below a second threshold at one of a series of troughs of a resonant ringing voltage waveform across the second switch, to cause current flow in a second direction in the primary winding to discharge a capacitance of the first switch to cause the first switch voltage to transition below the first threshold to initiate a subsequent converter cycle.

Abstract: A circuit includes a synchronous rectifier that receives an alternating current (AC) voltage from a transformer secondary and provides a rectified direct current (DC) output voltage in response to a control input signal.

The control voltage is employed to control switching of the secondary rectifier switching circuit based on the current in the transformer secondary. An offset circuit forces the control voltage in a predetermined direction to mitigate voltage error accumulations in the current replica circuit. A clamp circuit limits the control voltage to a predetermined voltage value.
