Abstract: The present disclosure carefully controls the heating duty cycle of a Lambda sensor, utilizing higher heating temperatures during lean phases, such as a fuel cutoff event or the like. Essentially, there is a calibration routine that is executed via software and allows a Lambda sensor to at least one of preserve full function over time and recover from an erroneous state. Advantageously, Lambda sensor life expectancy is increased accordingly. Optionally, the heating temperature for the Lambda sensor is selectively increased by increasing an applied voltage to the Lambda sensor.

Abstract: A method calibrates a camera having image sensor having a center position. An image view projected onto the image sensor by a lens is captured. At least one image view boundary of the captured image view is detected. A projection center position corresponding to a center of the projected image view is determined in at least one dimension. Offset between the projection center position and a sensor center position is determined, defined in at least one dimension, corresponding to the center of the image sensor capturing the projected image view. The image sensor is moved in relation to the lens based on the offset in order to arrive at a substantially zero offset in at least one dimension between the center of image sensor and the center of the projected image view.

Abstract: A method for setting up a monitoring camera includes tilting a camera head of the camera to a tilting position in which an optical axis of the camera substantially coincides with a rotational axis that the camera head is turning around when panning, and in which the camera head is able to capture images through a wide angle lens arranged in a fixed position in relation to a base of the camera. The camera head is turned around the optical axis of the camera and captures images until wide angle images captured through the wide angle lens present the desired orientation. A home position value for a pan motor of the camera is stored, wherein the position value represents the position value for the pan motor when the captured wide angle image presents the desired orientation.
