Abstract: A wearable electronic device for conveying information using one or more display indicators, wherein the electronic device comprises a housing; a nest positioned in the housing; a plurality of independently insertable and removable modules coupled to the nest, wherein each module comprises (i) a gearing arrangement comprising at least one rotateable gear and (ii) a stepper motor, the stepper motor comprising a rotor rotateably coupled to the at least one rotateable gear; a controller operatively coupled to the stepper motor of each module, for causing the rotation of the rotor of each module; wherein each of the plurality of modules has associated therewith and mechanically coupled thereto one or more display indicators; whereby the positioning of the one or more indicators conveys information by referring to particular indicia. In a specific embodiment, the wearable electronic device is a wristwatch.

Abstract: A display assembly for a wearable electronic device. The display assembly is disposed within a housing of the wearable electronic device. The electronic device is constructed to receive at least a first and second dial assembly each of which is adapted to provide a different display configuration. The display assembly comprises a liquid crystal display assembly comprising at least two display sections, driving means for providing driving signals to the respective display sections; and a controller, operatively coupled to the driving means, for signaling the driving means to provide the driving signals; wherein the display configuration of the wearable electronic device is changeable based on the dial assembly operatively coupled within the housing, wherein the first dial assembly provides for the viewability of at least the first display section and the second dial assembly provides for the viewability of at least the second display section.

Abstract: When compacting soil a vibration mass bearing on the ground is caused to vibrate, wherein the vibration process is controlled in dependence on the behaviour of the mass spring system, part of which being constituted by the soil. Tests have shown that in comparison with fall weights soil can be compacted up to the same extent in a shorter period of time or can be compacted to a greater extent in a same period of time.

Abstract: A guide framework for guiding a hammer in driving piles into subaqueous ground, said framework comprising a socket slidingly engaging the pile by means of a passage and at least one guide stay secured to the socket for guiding the hammer, the guide stay of said framework being detachably secured to the socket. As a result parts of the guide framework can be changed and the quantity of steel to be kept on stock for guide frameworks is small.

Abstract: In a pile driving device for driving a pile particularly into a soil located beneath a body of water, said device mainly comprising a hammer, a guide frame for guiding said hammer and suspension means for suspending the guide frame to a lifting device, said guide frame comprising a base piece surrounding the pile with sliding fit and at least one guide stay fastened to said base for guiding the hammer, the suspension means engage the hanger of the lifing device in a vertical plane of suspension extending transversely of the guide frame and located near the center of gravity of the driving device.During the pile driving operation almost the whole weight of the driving device hangs upon the derrick, so that this weight does not expose the pile to bending forces. The danger of buckling of the pile is reduced as a result.

Abstract: A pile driving ram for driving piles into subaqueous ground, during which a heavy piston operating as a hammer is each time lifted by fuel explosion in a cylinder, comprises a considerable and expensive cylinder piece, which has inlet and outlet ports and which comprises at least two guide girdles for supporting guide members co-operating with at least one guide stay of a guide frame. In order to increase the lifetime of the cylinder piece, the core is moulded from precious steel according to the fling moulding method.
