Abstract: A wireless power adapter uses a passive conversion circuit to convert an incompatible transmitter-receiver pair into a compatible transmitter-receiver pair. The wireless power adapter transfers power between a main transmitter and main receiver that are incompatible with each other. In one aspect, the wireless power adapter includes an auxiliary receiver coil system, a auxiliary transmitter coil system and a passive conversion circuit. The auxiliary receiver coil system is compatible with the main transmitter and can efficiently receive wireless power transmitted by the main transmitter that is external to the adapter. The auxiliary transmitter coil system is compatible with the main receiver and can produce wireless power to be efficiently transmitted to the main receiver. The passive conversion circuit connects the incompatible main transmitter and main receiver by transferring power from the auxiliary receiver coil system to the auxiliary transmitter coil system.

Abstract: Automated routing of signal nets for interposer designs. Signal nets are defined by their endpoints (bumps). The nets and their corresponding bumps are assigned to bump groups, based on the relative locations of the bumps and also based on length-matching constraints for the nets. Some of the bump groups may be “clones,” where the routing for one bump group may also be applied to its clone. In order for two bump groups to be clones, the bumps in the two bump groups must have a same relative position (i.e., same bump pattern), and the nets in the two bump groups must be subject to the same length-matching constraint. The routing through the interposer for one of the clones is determined, and that routing is then replicated for the other clones.

Abstract: A method for blockchain generation is provided. The method includes: sending, by a client, transaction information to a first node device, where the transaction information includes basic information and digest information; receiving, by the client, an endorsement result sent by the first node device, where the endorsement result includes a signature generated after the first node device successfully performs transaction simulation; and if the endorsement result meets a preset transaction condition, sending, by the client, the digest information and the endorsement result to a second node device, so that the second node device sends, to the first node device the digest information to generate a complete blockchain. In this way, only the digest information is transmitted between the first node device and the second node device. Therefore, the second node device does not obtain the complete transaction information, so that information security is improved.

Abstract: Arrays of low permittivity Polymer-based Resonator Antenna elements with different configurations. Individual array elements can be fabricated with complicated geometries; these elements can be assembled into complicated patterns as a single monolithic fabricated structure using narrow wall connecting structures, which removes the requirement to position and assemble the array elements. Monolithic array structures can be assembled as sub-arrays in larger array structures. Elements, sub-arrays, and arrays can also be formed by inserting dielectric materials into cavities defining their lateral geometries, and fabricated in polymer templates. The polymer templates can be removed or retained to function as part of the antenna.
