Abstract: This invention provides a system and method for detecting and acquiring one or more in-focus images of one or more barcodes within the field of view of an imaging device. A measurement process measures depth-of-field of barcode detection. A plurality of nominal coarse focus settings of a variable lens allow sampling, in steps, of a lens adjustment range corresponding to allowable distances between the one or more barcodes and the image sensor, so that a step size of the sampling is less than a fraction of the depth-of-field of barcode detection. An acquisition process acquires a nominal coarse focus image for each nominal coarse focus setting. A barcode detection process detects one or more barcode-like regions and respective likelihoods. A fine focus process fine-adjusts, for each high-likelihood barcode, the variable lens near a location of the barcode-like regions. The process acquires an image for decoding using the fine adjusted setting.

Abstract: A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

Abstract: In a transition of a transport unit of a long stator linear motor from a first control zone to a following second control zone in a movement direction, a first segment control unit is responsible for controlling the movement of the transport unit and the first control zone is extended, in the movement direction, by a number of virtual drive coils. The first segment control unit, which is assigned to the first control zone, calculates manipulated variables for the virtual drive coils, and transmits the manipulated variables for the virtual drive coils to the second segment control unit, which is assigned to the second control zone. The second segment control unit uses the transmitted manipulated variables for the virtual drive coils in order to energize the drive coils of the second control zone for moving the transport unit.
