Abstract: A calibration method (1) for a recording device (2). The method includes receiving, with a data interface (11) of a data processing system (3), a first data set (21) with an image and three dimensional information generated by the recording device (2). At least one person (4), within a field of view (8) of the recording device (2), is detected with an object detection component (12). Two or more attributes (5), of the person (4), are determined by an attribute assignment component (13). The attributes include an interest factor for an object and a location of the person (4). A descriptor (9) is generated based on the determined attributes (5). The data processing system calculates an attention model with a discretized space within the field of view based on the descriptor(s). The attention model is configured to predict a probability of a person showing interest for the object.

Abstract: A handheld power tool having a power tool that executes a reciprocating motion, in particular a reciprocating power saw with a reciprocating sawblade (14), is disclosed. To prevent the power tool from sawing untrue during the cutting operation, in particular between the upper and lower cutting edges, the power tool is assigned at least one force transducer (19), which measures the magnitude of a transverse force, oriented transversely to the direction of motion, that occurs at the power tool, and at least one actuator (21), which acts on the power tool as a function of the measured magnitude of the transverse force, is provided for transverse force compensation (FIG. 2).

Abstract: A portable electric power tool is specified, having a metal housing (10), at least a region of which is covered with at least one plastic part (26, 27). To cool that region of the metal housing (10) which gets very warm due to the plastic cover, means are provided which produce Can air flow (28) which is supplied from outside and sweeps over the metal housing (10) in the region of the plastic part (26).
