Non-limiting examples of the present disclosure relate to generation and implementation of a new security protocol that is used to secure common data access transactions across distributed network examples. An exemplary proof of verification protocol is disclosed that implements consensus security mechanisms across a plurality of distributed nodes, which may be utilized to validate owners of data in common data access transactions. Extending principles of blockchain security to common data access transactions and Internet of Things (IoT) networking requires a solution that: improves speed in transactional processing; reduces computational complexity; and presents efficient, secure and repeatable validation for owners of data in distributed networking environments. An exemplary proof of verification protocol provides such technical advantages by validating both user-specific data for a subscriber of an application/service and session data for user activity (past and present) within the application/service.

A power transmission device for a hybrid vehicle may include: an engine part; a transfer part configured to transfer power of the engine part; a motor part configured to provide power to the transfer part, and driven when power is applied thereto; and a plurality of torsion damper parts disposed between the engine part and the motor part, and connected in series.

A transmission module for a hybrid drive vehicle configured to be interposed between an internal combustion engine and a transmission of the vehicle has a tray-like support structure configured to be secured to the engine and defines a housing for a clutch to be interposed between a crankshaft of the internal combustion engine and the module. An actuator controls the clutch. The actuator includes an annular chamber provided in the support structure and opens toward the housing, and an annular piston housed in the annular chamber is axially sliding but angularly fixed. A thrust member is coupled in a rotationally free manner to the annular piston, coaxial thereto and operable to cooperate with a control member of the clutch under the thrust of the piston.
