Abstract: A system and method for validating an Internet of Thing (IoT) device on an IoT network. The IoT device captures and stores the historical sensor values, along with corresponding timestamps in a local memory. A controller receives the historical sensor values and also receives a heartbeat token over a network that is different than the IoT network. The controller calculates a historical hash value using the historical sensor value and the heartbeat token as inputs and stores the historical hash values and the corresponding timestamp in a blockchain ledger of an IoT management platform. At a later time, in response to a validation request from the IoT management platform, the controller polls the IoT device for the historical sensor value associated with a particular timestamp. The IoT device responds with the stored historical sensor value and the controller calculates a reconstructed hash value using the historical stored sensor value and a stored heartbeat token as inputs.

Abstract: A Tokenized Communication Service Provider (TCSP) for providing secure messaging between a consumer and a message sender without exposing the consumer communication preferences and Personally Identifiable Information (PII) to the message sender. TCSP issues a communication token to be used for the communication between the consumer and the message sender. Consumer authorization is recorded in a blockchain ledger and a Zero Knowledge Proof mechanism is used to establish that the TCSP possesses the consumer contact information and authorization. The consumer authorization is revocable by the consumer, and the revocation is recorded in the blockchain ledger.

Abstract: Systems, apparatus and methods are disclosed for coupling a wafer style primary element of a process measurement system between process pipes in a manner which aligns the primary element with the process pipes, while maintaining alignment and preventing leaking in the event of a dynamic shock to the process pipes.

Abstract: A method of simulating an analog mixed-signal circuit design using mixed-language descriptions includes initializing a mixed language simulation cycle, processing digital events during delta cycles at a current simulation time of the cycle, and, after the digital events are processed, determining an analog solution at the current simulation time.

Abstract: Improvements in wiring assemblies using an electrical junction box assembly having preset electrical terminals. Such present terminals are hard-wired to certain electrical connection devices near the outer periphery of the box. Electrical components, such as a switch, a receptacle and the like can be quickly and easily mounted in place in the box in electrical contact with respective preset terminals. The selective electrical component can be provided with a number of pins at predetermined locations for electrical contact with certain of the preset terminals. One or more power-receiving members, such as a light fixture, can be coupled to respective outer peripheral electrical connection devices for receiving the three or four individual wires of an electrical line from each power-receiving member.
