  • Patent number: 11338425
    Abstract: Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.

  • Patent number: 11268801
    Abstract: A method for determining a position of a movable object is disclosed. The method comprises generating an electromagnetic exciter field. The electromagnetic exciter field is configured to excite the movable object to develop a magnetic response field. Further, the method includes determining a plurality of measurement values for the magnetic response field by measuring the magnetic response field at a plurality of predetermined measuring positions. Further, the method includes determining the position of the movable object based on a comparison of the plurality of measurement values with reference measurement values. Here, one position of the movable object is allocated to each of the reference measurement values. Further, the reference measurement values are each determined by a simulation.

  • Publication number: 20210248125
    Abstract: An in-memory database server hosting a tenant of a multi-tenant software architecture can receive a definition of a custom data field that is unique to an organization having isolated access to the tenant. The custom data field can extend a standard table defined by central metadata stored at a system tenant of the multi-tenant software architecture. Tenant private metadata that includes the definition can be stored in memory accessible only to the tenant. A tenant-dependent table that includes the custom data field can be formed, for example by retrieving central metadata defining the standard table from the system tenant and adding the custom data field using the definition. The tenant-dependent table can be presented for access via a database client at the organization. Related systems, articles of manufacture, and computer-implemented methods are disclosed.

  • Patent number: 10821590
    Abstract: A hand-held machine tool for a striking tool has a motor, an impact mechanism, a spool valve, and a pneumatic chamber. The impact mechanism has an exciter piston moved by the motor, and a hammer coupled to the exciter piston via a pneumatic chamber between the exciter piston and the hammer, and a striker in front of the hammer in the striking direction. In a working position counter to the striking direction, the striker bears on a stop, in a starting position the striker is offset in the striking direction relative to the working position, and in a rest position the striker is offset in the striking direction relative to the starting position. In the starting position, the hammer bearing on the striker closes the spool valve and, in the rest position, the hammer bearing on the striker opens the spool valve.
