Abstract: Provided is a design method for sharing a profile in a container environment, including: extracting a sensitive context defined as information related to system-based access control or a sandboxing policy and an insensitive context defined as information unrelated to security for a profile provided by a developer; extracting the sensitive context and the insensitive context for the profile provided by a host; fetching a max configuration for the sensitive and insensitive contexts from each image layer of the developer; and generating a final profile that is applied to deploy the container by merging the host profile with the max configuration fetched from the developer profile. Accordingly, it is possible to provide an optimal environment to developers and hosts by generating the final profile with a hierarchical model using the host profile and the developer profile.

Abstract: The present invention relates to a harmonic gear device in which a first similarity curve obtained by similarly transforming a reference curve representing a moving locus of an external tooth with respect to an internal tooth in a non-deflected state and a second similarity curve generated by similarly transforming the first similarity curve are used as a criterion for generating a tooth profile, wherein the present invention may provide the harmonic gear device that enlarges a first curve represented by a moving locus of positive deflection located above the apex of the reference curve among the moving loci of positive deflection of the external teeth on the basis of the reference curve to approximate an approximate reference point arranged on the second similarity curve to create a second curve, and uses the second curve as the top of the tooth profile of the external tooth.

Abstract: A battery diagnosis apparatus determines whether a battery may be reused and includes a data obtaining device configured to output a perturbation signal, a signal regulating device configured to generate a current by applying the perturbation signal to a battery and performing feedback of a current signal output from the battery, and a noise canceling device configured to cancel noises of the current signal and a voltage signal received from the battery. The data obtaining device outputs the perturbation signal while changing a frequency, obtains an impedance spectrum based on the noise-canceled current signal and voltage signal for each frequency, and determines whether to reuse the battery based on the obtained impedance spectrum.
