Digitally printed products and process

A process for manufacturing three-dimensionally shaped polymeric sheets and laminates with color-matched digitally printed full color ink jet images. A flexible thermoformable polymeric baseweb is placed in an ink jet printer and a solvent-based (non-aqueous) digital printing ink is applied directly to the baseweb, in the absence of an ink receptive layer on the baseweb, to form a decorative pattern in multiple colors in a single pass through the printer. The finished product can be thermoformed or injection molded to a three-dimensional shape. A protective topcoat can be laminated to the digitally printed sheet prior to the thermoforming and/or injection molding step. A process for making color-matched products comprises producing a software-driven image of a pattern on a screen representing a standard color print pattern; evaluating and adjusting the standard displayed on the screen using software-driven image related adjustments for hue, contrast, lightness/darkness, etc.; producing a test print by applying a decorative pattern to the baseweb by a digital ink jet printer and making an optional software-driven image-related adjustment in the standard to color match the standard to the test print image; and when the adjusted standard image displayed on the screen is acceptable, passing an image-related output to the digital ink jet printer for printing a decorative print color-matched to the accepted onscreen standard.

Automatic classifying and networking method for bluetooth equipment

The invention relates to an automatic classification networking method for Bluetooth devices in the technical field of wireless communications, wherein, the method comprises the following steps: the Bluetooth devices are classified according to the classification standard of the Bluetooth devices; the Bluetooth devices are connected within the communication scope and then obtaining attribute information of the counterpart for verifying that whether the Bluetooth devices belong to the same class, and if yes, the Bluetooth devices are connected; if no, the Bluetooth devices are disconnected. Thus, the Bluetooth devices belonging to the same class in the communication scope are connected and combined into a plurality of isolated scattering networks. A super peer in each isolated scattering network is determined for marking the scattering network. Each isolated scattering network sends out a detecting message. Bluetooth devices which are different from the Bluetooth devices for networking are selected as bridge access points for connecting the scattering networks in the region to form a global network. With the least quantity of the scattering networks, the method can not only ensure the connectivity, but also improve the average transmitting speed, reduce the energy consumption of the whole scattering network, etc.

Dual antenna

A dielectric dual antenna intended especially for small-sized radio devices, by one partial antenna of which is implemented the lower operating band of the antenna and by the other partial antenna the upper operating band. The partial antennas have a shared substrate (440), which together with the radiators constitutes an integrated antenna component (400). The partial antennas also have a shared feed point (FP), the part of the antenna component to one direction from the plane, which leads through the feed point and is perpendicular to the upper surface of the substrate, belonging to one partial antenna and the part of the antenna component to the opposite direction belonging to the other partial antenna. At least one of the partial antennas comprises two radiators, the first one (411) of which joins the feed point and the second one (412) is connected to the ground (GND) from its outer end as viewed from the first radiator. This first radiator (411) and the radiator (421) of the other partial antenna, which joins the shared feed point, form a unitary common element (430) on the substrate surface. This common element is shortcircuited to the ground from at least one point (SP1, SP2) relatively near to the feed point. The matching of the dual antenna can be improved in either operating band without degrading it in the other operating band at the same time.

Distributed electric quantity transaction block chain storage method and device based on Merkel tree

The invention provides a distributed electric quantity transaction block chain storage method and device based on a Merkel tree, and relates to the technical field of block chains, and the method comprises the steps: extracting a key element field from obtained transaction information; establishing a Merkel tree according to the key element fields, and calculating a first hash value of a tree root; broadcasting the key element field and the first hash value at the same time in the blockchain network, updating the first hash value into the block after a consensus is formed, and storing transaction information locally by the main node; establishing a new Merkel tree according to the actual delivery information and the transaction information, and calculating a second hash value of a new treeroot; broadcasting the new key element field and the second hash value at the same time in the blockchain network; and after a consensus is formed, updating the second hash value into the block, wherein the main node locally stores actual delivery information. Therefore, the scale of the uplink data is reduced based on the storage technology of the Merkel tree, and the complexity of information storage and updating in the matching, settlement and checking stages of the transaction is reduced on the premise of ensuring the safety and traceability.

The invention relates to an artificial knee-joint thighbone which belongs to the technical field of prosthesis. The artificial knee-joint thighbone comprises a preartis, a first thighbone joint face, a second thighbone joint face and an insertion block. The first and second thighbone joint faces are parallely arranged on one side and connected with the preartis on the other side to form a gap structure. The insertion block is arranged between the preartis and the first and second thighbone joint faces. One end of the insertion block is located in the middle of the preartis while the other end of the insertion block is located in the middle of the first and second thighbone joint faces. The preartis is in a corrugate structure and comprises two wave crests and a pulley groove in the trough between the wave crests. A strength enhancing part is arranged inside the side face of the preartis. According to the invention, a concave design of the pulley groove is adopted for the preartis of the thighbone, so that the preartis is relatively thinner, and the osteotomy amount of the preartis is reduced to better meet the anatomical features of the thighbone and improve match of patella articular surface and match of force line of lower limbs of a human body. Meanwhile, the strength enhancing part is arranged between the pulley groove of the preartis and the thighbone interface of the human body to enhance the thickness of the pulley groove, so as to ensure the strength of the preartis. The shape and the structure of the artificial knee-joint thighbone are more suitable for patients, and the morbidity of anterior knee pain is reduced.
