Abstract: A module assembly for the detection of X-ray radiation includes an X-ray sensor being configured to receive a photon of the X-ray radiation and to provide an electrical signal in response to the received photon. The module assembly further includes a system-in-package structure for processing the electrical signal, the system-in-package structure including an input/output terminal, a first interposer and a second interposer and an integrated circuit which are arranged in a stacked configuration in the system-in-package structure. The package structure can be assembled on all four lateral sides and is thus four-side buttable so that contiguous modules can be mounted on all four sides without a gap between pixels to read out data from large-pixelated detectors of the X-ray sensor.

Abstract: A sensor module including a sensor and a transparent body which is provided over the sensor, wherein the transparent body comprises a base portion and a convex lens which extends outwardly from the base portion and is located above the sensor, wherein an opaque material is provided on the base portion and surrounds the convex lens.

Abstract: A motor driven angle grinder is described and which includes an electric motor; a transmission coupled to the electric motor and which includes a motor shaft and a tool spindle; a crown wheel in the form of a hat is provided and which forms a recess that receives the tool spindle and a bearing, and wherein the crown wheel defines toothing which surrounds the recess, and wherein the transmission housing and the angle grinder have low relative height profiles which permits the angle grinder to be used in restricted or tight space working environments.

Abstract: A packaging machine and a device for monitoring a roll with film material wound thereon is disclosed. By means of a sensor arrangement, an end of the film material on the roll may be detected. The sensor arrangement includes at least one optoelectric sensor arranged stationary relative to a front side of the roll. The optoelectric sensor is designed such that a portion of an outer circumference of the rotating roll may be detected.
