Abstract:
The invention relates to a method for producing micro-structured shaped parts (22) and the resulting products, wherein a first negative or positive photosensitive layer (12) with a layer thickness (D1) is deposited on a substrate (10) and the first negative or positive photosensitive layer (12) is exposed area-by-area with light of a suitable wavelength; a second negative or positive photosensitive layer (12′) with a layer thickness (D2) is deposited on the first negative or positive photosensitive layer (12) and exposed area-by-area with light of a suitable wavelength, wherein the exposed regions (16′) in the second layer (12′) are identical to and/or different from the exposed regions (16) in the first layer (12); the steps of depositing and exposing the photosensitive layer (12, 12′) area-by-area are performed repeatedly until a predetermined height H is attained, wherein the exposed regions (16, 16′) of the photosensitive layers (12, 12′) represent the positive or negative of the microstructure of the shaped part (22); the exposed (16, 16′) or the unexposed regions (18, 18′) of the shaped part (22) are washed out with a developer; and the remaining preform (20) is subsequently solidified.
Abstract:
A system and method for providing a fault-tolerant remote controlled computing device. A multi-tasking operating system and at least one primary process are executed on the computing device. A first monitor process determines whether any primary process is in a fault state. In response to any primary process being in a fault state, the first monitor process resolves the fault state of each such primary process. In certain embodiments, a local copy of a common configuration file and multimedia content are stored on the computing device. The computing device polls a server at pre-determined time intervals via a public Internet connection for updates to one or more processes, the local copy of the common configuration file, and the multimedia content. In response to updates being available from the server, the computing device downloads one or more updates via a fault-tolerant network connection and plays the multimedia content based on instructions contained within the local copy of the central configuration file. In one configuration, a user-defined notification system is provided which allows users to define threshold values. Once the threshold values are satisfied, one or more users may be notified.
Abstract:
The invention relates to a machining tool (14) for machining materials by removing material, in particular for wood or wood-like materials, metals, plastics and/or composite materials. The machining tool is provided to be driven in rotation about an axis of rotation (1) and comprises at least one row (17, 18, 19) of individual cutters (2, 2″) arranged in the peripheral direction and having cutting edges (3, 3″) which at least partly overlap. The cutting edges (3, 3″) have a rake angle and are located at an axial angle (λ) in relation to the axis of rotation (1). The axial angle (λ) lies in a range from 55° to 55°.
