Abstract: Illustrative embodiments of impact tools with impact mechanisms rigidly coupled to electric motors are disclosed. In at least one illustrative embodiment, an impact tool may comprise an impact mechanism, an electric motor, and a control circuit. The impact mechanism may comprise a hammer and an anvil, the hammer being configured to rotate about a first axis and to periodically impact the anvil to drive rotation of the anvil about the first axis. The electric motor may comprise a rotor that is rigidly coupled to the impact mechanism, the electric motor being configured to drive rotation of the hammer about the first axis. The control circuit may be configured to supply a current to the electric motor and to prevent the current from exceeding a threshold in response to the hammer impacting the anvil.

Abstract: The present invention 10 discloses a resilient headband 14 arcuate in shape for being mounted on the head of the user 12. The headband 14 is equipped with a longitudinal slotted member 16 for holding a placard 18 therein, in a generally upright standing manner which placard 18 can have written thereon on one side a thought balloon 19 and on the opposite side a speech balloon 19. The slotted member 16 is equipped with teeth-like holding appendages 22 which grasp the placard 18 and secure it to the slotted member 16.
