1. A device comprising:
- a housing having an impact receiving surface on an external portion of the housing;
a powered element disposed on or in the housing; and
an impact power producing element housed on or in the housing and operatively connected to the powered element, the impact power producing element producing power upon an impact of the impact receiving surface with another surface;
wherein the impact power producing element comprises a piezoelectric element, a mass and one or more spring elements connected at a first end to the mass and at a second end to the piezoelectric element such that the impact sets the mass in motion causing the one or more spring elements to exert a force on the piezoelectric element.

8. A flashlight comprising:
-
a housing having an impact receiving surface on an external portion of the housing; a light source disposed in the housing; and an impact power producing element housed in the housing and operatively connected to the light source, the impact power producing element producing power upon an impact of the impact receiving surface with another surface; wherein the impact power producing element comprises a piezoelectric element, a mass and one or more spring elements connected at a first end to the mass and at a second end to the piezoelectric element such that the impact sets the mass in motion causing the one or more spring elements to exert a force on the piezoelectric element.

9. A device comprising:
-
a housing; a powered element disposed on or in the housing; a piezoelectric element disposed in the housing and operatively connected to the powered element to provide power to the powered element; and a mass-spring unit disposed in the housing, the mass-spring unit comprising a mass and at least one spring, the at least one spring being connected at one end to the mass and at another end to the piezoelectric element, the piezoelectric element producing power upon an impact of at least a portion of the housing with another surface to vibrate the mass-spring unit and exert a force on the piezoelectric element. - View Dependent Claims (10, 11)
