  • Patent number: 12647272
    Abstract: Described in detail herein is a nested blockchain system. The nested blockchain system can include distributed nodes in a network. A node is configured to generate a master cryptographically verifiable distributed ledger represented by a sequence of blocks. The node spawns a first sub cryptographically verifiable ledger represented by a first genesis block containing a hash value referencing the first block generated in the master cryptographically verifiable ledger, in response to a first event. The node purges the first sub cryptographically verifiable ledger, in response to a second event.

  • Publication number: 20220153332
    Abstract: Infant carriers are stably supported and transported by being positioned on a frame set on wheels. The frame may include an infant carrier holder with a floor with a ramp and sidewalls. The infant carrier holder may be integral with the frame or may be mounted to a mounting device that can be adjusted for mounting angle or height. A handle is provided to the frame at a position that is suitable for a person in a wheelchair to grasp the frame and move the transport. A handle suitable for a standing person to grasp the frame may optionally be provided. The transport permits a person that may have difficulty carrying or transporting an infant carrier to more easily transport the infant carrier in a standing or a seated position, the latter as may be the case with a wheelchair occupant. The transport may be fastened to the wheelchair.

  • Publication number: 20220063694
    Abstract: An infant carrier holder has a floor with a ramp and sidewalls and is mounted to a shopping cart. The ramp and sidewalls can contribute to stably supporting an infant carrier. The holder serves as a mechanical interface between an infant carrier, which can be received in the holder, and the shopping cart. The holder can be concavely shaped to assist in shopping cart nesting in addition to supporting a received infant carrier at a desired angle. The holder can be adjustably mounted to a gate or a basket of the shopping cart and may/may not interfere with nesting operations. The holder permits an infant carrier to be supported on a shopping cart without using a significant amount of shopping cart space or interfering with nesting operations.

  • Patent number: 11184171
    Abstract: Described in detail herein is an multi-variant tracking system. Independently operated domains can be associated with a cryptographically verifiable ledger represented by a sequence of blocks. The central computing system can receive an alert of a creation of a new block in a cryptographically verifiable ledger associated with a first independently operated domain. The central computing system can determine one or more independently operated domains affected by a change in a first data value of a first type. The central computing system can determine a type of a type of data value associated with other transaction records in each cryptographically verifiable ledger for each of the independently operated domains. The central computing system can convert the change in the first data value of the first type to a corresponding change in a data value of a different type of data value.
