Abstract: A base device which can raise or lower a display panel suspended therein includes a fixing frame, a hanger for fixing the panel, two sliding rods, a connecting seat, a driving device, and a screw rod. The fixing frame includes two fixing rods spaced apart from each other and a base connected between the two fixing rods. The two sliding rods are connected to the hanger and slidably fixed to the two fixing rods. The connecting seat is fixed between the two sliding rods. The screw rod is fixed on the base. The driving device is fixed on the connecting seat and slidably connected to the screw rod. When the driving device is moved, manually or by motor, up and down along the screw rod the hanger carrying the panel is lifted up or lowered.

Abstract: A device for inserting elements into the ground in order to carry out works includes a positioning mechanism. The positioning mechanism includes an upper panel which is fixed to the chassis of a vehicle for transporting the insertion device, a movable plate to which an insertion arm is fixed, and at least six jacks which can be controlled so as to allow movement of the movable plate relative to the upper panel with six degrees of freedom, each jack being directly fixed, at one side, to the upper panel and, at the other side, to the movable plate of using connections which have three degrees of freedom in terms of rotation.

Abstract: The measurement data fairing method comprises: a fitting interval determination step (S14) for determining an interval in which a geometrical element is to be fitted to measurement data; a geometrical element fitting step (S22) for extracting, from the data, interval measurement data of the fitting interval and robustly fitting the element; an outlier removal step (S24) for removing, on the basis of a result of the robust fitting, outlier from the interval measurement data; a statistic computation step (S26) for computing a statistic of a residual of the interval measurement data after the step (S24); and an invalid data removal step (S28) for removing, as invalid data, measurement data that exceeds a predetermined limit value of the statistic of the residual from the interval measurement data after the step (S24) on the basis of the statistic of the residual computed in the step (S26).

Abstract: A probe head for orientating a probe relative to a head of a coordinate measuring machine, has a support a rotor rotatable relative to the support, and a swivel rotatable relative to the rotor. The rotor and swivel are mounted for rotation through a series of discrete, and repeatable rest positions. The relative orientation of support, rotor and swivel is detected by an indicating mechanism comprising a printed circuit board having a series of electrical conductive elements and a contact arm mounted for rotation over the conductive elements on the circuit board. When the electrical contacts of the contact arm come into register with the conductive elements on the circuit board a pulse is transmitted to a micro-processor which determines the relative orientation of e.g. the support and rotor which is shown on the LCD.

Abstract: A two-dimension vernier scale utilizing a cartesian grid on one plate member with a polar grid on an overlying transparent plate member. The polar grid has multiple concentric circles at a fractional spacing of the spacing of the cartesian grid lines. By locating the center of the polar grid on a location on the cartesian grid, interpolation can be made of both the X and Y fractional relationship to the cartesian grid by noting which circles coincide with a cartesian grid line for the X and Y direction.

Abstract: A base structure supports a relatively rotatable and vertically adjustable platform upon which the wearer of a garment to be fitted stands, the base structure further supporting a relatively fixed stool for the dressmaker's use in effecting hemline marking, pinning and the like of the garment being fitted and including storage compartments within handy reach of the dressmaker seated on the stool.
