Abstract: Various embodiments include computer-aided systems and methods for training a user in conducting negotiations. An example method includes: providing data of a first type using recordings of real or virtual negotiations of one or more users with of one or more recording devices after corresponding computer-aided processing; and communicating the data of a first type to an artificial intelligence for generating data of a second and a third type. Data of a second and a third type are presented on an output device, which give the user a conception of the AI-calculated reaction and/or consequence of the user's recorded negotiation, subsequently and also in real time, during the ongoing negotiation.

Abstract: A toilet tank lever assembly may be mounted in various toilet tanks by selective positioning of a long lever arm relative a short lever arm. One such lever assembly include a long lever arm which may be mounted at an infinite degree of adjustment relative a short lever arm as provided by a ball and socket interface between the lever arms. The ability to reverse the short lever arm essentially doubles the number of mounting possibilities. By selecting between a front insert and a side insert, a handle is readily positioned for either front or side tank mounting. Various handles may also be readily attached to the lever post to provide various aesthetic appearances.
