Abstract: An accessory wand handle for use on existing control wands. An elongated handle with a bore is fitted over the end of an existing wand for blinds. The handle is secured on the existing wand by a frictional fit between the outside surface of the existing wand and the inner surface of the bore in the accessory wand handle. The wand handle is larger than a wand to provide a mechanical advantage for users to turn the wand. The wand handle itself can be constructed to compliment the appearance of the wand. There is sufficient space between the wand and the walls of the bore for placement of decorative items. The handle itself may be decorated or inscribed with logo or other promotional materials.

Abstract: An apparatus for generating a seismic signal in a wellbore includes an elongated housing configured to be disposed in the wellbore; a piston slidably disposed in an internal bore in the elongated housing; a strike plate fixed on the elongated housing proximate one end of the internal bore; and an energizing mechanism configured to move the piston to hit the strike plate. A downhole system for seismic survey of a formation penetrated by a wellbore includes at least one seismic receiver; a seismic source; and at least one inflatable packer configured to separate the seismic source and the at least one seismic receiver in different compartments in the wellbore when inflated.
