Abstract: An electronic device that comprises a component, communication port, and a controller coupled to the component and the communication port. The controller is to store operational data of the component during operation of the electronic device. The controller is to provide the operational data to a peripheral device coupled to the electronic device in response to the electronic device establishing a wired connection to the peripheral device via the communication port, the operational data secured by a security credential of the controller. The controller is to receive a repair command from the peripheral device based on the operational data. The controller is to correct a malfunction of the component based on the repair command.

Abstract: In examples, an electronic device comprises a component, communication port, and a controller coupled to the component and the communication port. The controller is to store operational data of the component during operation of the electronic device. The controller is to provide the operational data to a peripheral device coupled to the electronic device in response to the electronic device establishing a wired connection to the peripheral device via the communication port, the operational data secured by a security credential of the controller.

Abstract: The present invention relates to a piston with a central valve, in particular for hydraulic boosters, the valve case (6) which is composed of a supporting insert (8) radially embraced by a valve seat (7). It is disadvantageous in some valve cases that sometimes the positive coupling between the two elements in axial direction is not sufficient. The present invention provides a remedy to this problem by using undercuts behind which the valve seat engages the supporting insert in both directions. In an advantageous improvement, the valve insert is of symmetrical design, and a sealing projection is shaped at the valve seat. The guidance of the valve tappet (19) is performed within the piston (1).

Abstract: Apparatus for cooling hops comprises a cooling chamber, charging means for hops to be cooled at one end of the chamber, discharging means for cooled hops at the other end of the chamber, a gas-permeable surface within the chamber for supporting a bed of hops, means for conveying hops deposited on said surface by said charging means towards said discharging means, means for maintaining a bed of hops of predetermined depth on said surface and means for passing cold gas through the bed of hops on said surface. In order to reduce adverse effects on the cooling conditions, both the charging and discharging means are constructed as air locks. The gas-permeable surface and the means for maintaining the bed of hops at a predetermined depth are preferably both endless mesh screen conveyor belts. Means for cooling and recycling gas may be associated with the cooling chamber and the whole apparatus may be integrated in a continuous lupulin recovery process.
