    Abstract: A microphone system has a package forming an interior chamber, and a MEMS microphone secured within the interior chamber. The package forms an aperture for permitting acoustic access to the interior of the chamber and thus, the MEMS microphone. The system also has two dies; namely, the system has a primary circuit die within the interior chamber, and an integrated passive device die electrically connected with the primary circuit die. The primary circuit die is electrically connected with the MEMS microphone and has at least one active circuit element.

    Abstract: Embodiments of the present disclosure provide code readers for reading codes provided as patterns imprinted on objects. Light interacts with a pattern by e.g. being reflected from or transmitted through the pattern, and at least some of the light that has interacted with the pattern is incident on photosensitive element(s) of one or more photodetectors of a code reader. The code reader employs centroid-measuring photodetector(s), i.e. photodetectors that detect light in such a manner that centroid of a pattern can be obtained directly from the photocurrents generated as a result of the photosensitive elements detecting light incident thereon. The code reader is then configured to process the detected light to determine a centroid of the pattern from the detected light and to decode data encoded in the pattern based on a position of the centroid. Such code readers are substantially less complex than camera-based devices and avoid mechanical scanning.
