The present disclosure relates to a device for simultaneously performing printing of tablets and inspection on exteriors of the tablets, and provides a device for printing a tablet and inspecting an exterior of the tablet, comprising a transfer unit arranging and transferring tablets supplied from a tablet supplier in a line; a pre-printing image-capturing unit located on a transfer path on which the tablets are transferred to discriminate positions and orientations of the tablets, and disposed to capture images of exteriors of the tablets being transferred; a tablet printing unit located next to the pre-printing image-capturing unit on the transfer path on which the tablets are transferred, and printing the tablets being transferred, in consideration of discriminated results acquired from the images captured by the pre-printing image-capturing unit; and a post-printing image-capturing unit located next to the tablet printing unit on the transfer path on which the tablets are transferred, and capturing images of exteriors of the printed tablets being transferred, to inspect the images or printed results of the printed tablets. According to an embodiment of the present disclosure, a plurality of functions may be performed with a single device, to maximize work efficiency in time and space, and reduce costs.

A image processing device which can reduce information such as a pattern, a scar and the like on a surface of a drug which are other than an engraved mark, to accurately extract the engraved mark. The image processing device includes: an obtaining unit configured to obtain a plurality of images of a drug having an engraved mark on a surface of the drug, with emitting directions of light to the surface different from each other; an edge image generating unit configured to apply respectively to the plurality of images, edge extracting filters in directions in conformity with the emitting directions, the edge extracting filters having a size in conformity with a width of a groove of the engraved mark, and generate a plurality of edge images; and an image composing unit configured to compose the plurality of edge images and generate a composite image.

Disclosed is a radio antenna comprising a substrate of dielectric material; a ground plane of electrically conductive material on a first face of the substrate; a resonator for converting an incident electrical signal into an electromagnetic wave and for resonating at at least two different resonant frequencies. The resonator comprises at least three elements, each in the form of strips of conductive material and arranged on a second face of the substrate opposite the first face. A second element is electrically connected to the ground plane by means of a via passing through the substrate at a first end of the corresponding strip, forms an extension of the first element, and is electrically connected directly to the first element at a second end of said strip which is opposite the first end.

Apparatuses for use with a pharmaceutically acceptable carrier. The apparatus can include a partial power source, which in turn includes electrodes or materials that are configured to generate an electrical potential upon contacting or being exposed to an ionic solution. The apparatus can further include a circuit electrically or communicatively coupled to the partial power source. The circuit can generate various types of signals, such as RF signals, when powered by the partial power source. The circuit is stably fittable to the pharmaceutically acceptable carrier. The apparatus can further include a barrier, a protective layer, or a membrane that isolates the electrodes or materials from the ionic solution and is configured to be dissolved by the ionic solution.

Embodiments of a method and system for applying patterns on the surfaces of articles and inspecting the patterns are disclosed. A laser irradiation system has a laser transmission element, irradiation zone and irradiation inspection element. A set of articles is positioned within the irradiation zone and irradiated with laser energy from the transmission element during an irradiation period. The irradiation causes interactions between a beam and the article surfaces which transiently generate localized illuminations at the article surfaces during the interactions. The interactions also collectively form post-irradiation patterns in the article surfaces that persist after the interactions. An irradiation inspection image of the irradiation zone is captured during the irradiation period by the irradiation inspection element. The irradiation inspection image includes illumination patterns defined by the localized illuminations. If an illumination pattern fails to match the corresponding target pattern to which it is compared, the respective article is rejected.

A computer-implemented method for printing customized 3D medication based on the current user data and one or more medical records of the user. The method obtains current user data via one or more user IoT sensors and accesses one or more medical records of the user. The method further determines a medication design based on the obtained current user data and the accessed one or more medical records of the user and prints a 3D medication based on the determined medication design.
