A tablet for pharmaceutical use has on at least one part of its surface a diffractive microstructure which generates diffraction effects which can be perceived in the visible spectral range and which serve as visual safety feature. The tablet includes a plurality of individual powder particles, where the diffractive microstructures are impressed into the surface of the individual powder particles. A compression tool to produce such tablets has on one pressing surface of the compression tool micro-structures, where the microstructures have dimensions which are smaller than the dimensions of the individual crystallites of the material of the pressing surface of the compression tool. The micro-structures of the compression tool can be produced for example by ion etching or by imprinting.

A method, a computer program product, and a computer system provide medications to a patient with a time gap. The method includes determining a dissolving pattern for the patient. The dissolving pattern includes a medication dissolving rate for a first medication prescribed to the patient and a filler dissolving rate for a filler selected so that the time gap is elapsed prior to a second medication being provided after the first medication. The medication dissolving rate and the filler dissolving rate are specific to the patient. The method includes determining dimensions of the first medication to correspond to a dosage of the prescribed first medication and dimensions of the filler to correspond to the time gap. The method includes providing a pill including at least the first medication and the filler, the first medication surrounding the filler such that the first medication is dissolved prior to the filler being dissolved.

A method for anti-counterfeiting and identification of products includes manufacturing multiple marking units with different characteristics, performing an arrangement and combination operation on the marking units to design multiple arrangement marks that are not repeated, recording the arrangement marks to construct a record datebase, and setting each of the arrangement marks with the marking units on a target product such as a medicine. After the consumer purchases the target product, the photos of the target product and the record datebase are identified and compared to judge the authenticity of the target product.

An inkjet head cleaning apparatus 1 that moves an inkjet head 10 from a printing position P1 to a cleaning position P2 to perform cleaning, the inkjet head cleaning apparatus 1 comprising a conveying means 20 for conveying the inkjet head 10 between the printing position P1 and the cleaning position P2 and a cleaning means 30 for cleaning a discharge surface 12 of the inkjet head 10 conveyed to the cleaning position P1, wherein the conveying means 20 changes the orientation of the inkjet head 10 such that the orientation of the discharge surface 12 of the inkjet head 10 is different in the printing position P1 and in the cleaning position P2.

The present invention relates to a verification method of tablets, in particular pharmaceutical tablets. It further relates to an invisible secure marking or information which is a part of such tablet. The invention further relates to tablets suitable for such verification method, to processes for manufacturing such tablets and methods for reading the information.

Various devices and methods covering a technology for combinatorial liquid handling. At least some example embodiments of the devices may include a plurality of liquid dispensers configured to dispense drops, wherein at least a carrier drop is dispensed and sequentially collides and merges with drops dispensed from a sub-plurality of liquid dispensers, so that liquids from the sub-plurality of liquid dispensers are located in the carrier drop during flight, and a support surface being positioned so that the carrier drop lands on the support surface.

A capsule marking device 1 includes: a conveying unit 2 that conveys a capsule C along a conveyance path 2a; a first imaging unit 30 that captures an image of the capsule C being conveyed, to obtain first imaging data; a marking unit 40 that performs marking on the capsule C being conveyed; and a control unit that sets a marking region on the capsule C on the basis of the first imaging data, and forms a marking pattern in the marking region by controlling the operation of the marking unit 40. The capsule marking device 1 further includes a separating unit 60 that selectively separates the capsule C being conveyed from the conveyance path 2a, and the control unit controls the operation of the separating unit 60 to separate the capsule C having a seam with a size equal to or larger than a predetermined reference size in the marking region in the first imaging data without forming a marking pattern.
