Abstract: A changeover apparatus for changing between workpiece supports for a machining machine. The changeover apparatus has a base frame with a carrier apparatus for the workpiece supports, which are vertically movable by the carrier apparatus, with the result that one of the workpiece supports can be transferred into a working plane in which the workpiece support is moved from the carrier apparatus into the machining machine and guided out therefrom. A lifting apparatus acts between the base frame and the carrier apparatus and by way of which the carrier apparatus can be vertically moved relative to the base frame for one workpiece support to take up a first lifting position or a further lifting position in the working plane. The lifting apparatus contains a slotted guide, which movably actuates the carrier apparatus with the workpiece supports together between the first lifting position and the further lifting position.

Abstract: A companion electronic device includes a communication interface, one or more processors operable with the communication interface, and an authentication device operable with the one or more processors. The one or more processors can be actuated by power received from the communication interface upon the communication interface establishing electronic communication with another electronic device. The one or more processors can delivering signals to the communication interface enabling one or more functions of the other electronic device upon confirming authentication data received by the authentication device after the one or more processors are actuated belongs to an authorized user of the companion electronic device.

Abstract: A method in an electronic device designates, with one or more processors of the electronic device, at least one data item stored within a memory of the electronic device for storage in a plurality of remote electronic devices. The method encrypts, with the one or more processors, the at least one data item to create at least one encrypted data item. The method divides, with the one or more processors, the at least one encrypted data item into a plurality of encrypted subset data items. The method then delivers, with a communication device, at least a first encrypted subset data item from the plurality of encrypted subset data items to a first remote electronic device and at least a second subset data item from the plurality of encrypted subset data items to a second remote electronic device.

Abstract: An electronic device comprises one or more sensors capturing media content while the electronic device is situated at a media content capture location. A user interface receives user input requesting transmission of the media content to another electronic device situated at another electronic device location. One or more processors determine whether the media content capture location and the another electronic device location are substantially different locations, and at least temporarily preclude, in response to the user input, the transmission of the media content to the other electronic device when the media content capture location and the another electronic device location are substantially different locations.

Abstract: A method (202) for etching photolithographically produced quartz crystal blanks for singulation. In a first step (202), a quartz wafer is plated on both sides with metal and subsequently coated on both sides with photoresist. In a second step (204), the photoresist is patterned and developed and the metal layer on one side is etched through to form a narrow channel in the quartz defining a perimeter of a quartz blank. In a third step (206), the quartz channel is preferentially etched partially into the wafer along parallel atomic planes to provide a mechanically weak junction between the quartz wafer and the blanks to be singulated. In a fourth step (208), the photoresist layers are stripped from the quartz wafer. In a final step (210), the quartz blank is cleaved substantially along the bottom of the quartz channel to singulate the crystal blanks from the quartz wafer.
