Thermal imaging camera images are obtained from a thermal imaging camera that rotates through a plurality of stop positions. The camera captures images at a constant frame rate and at least some of the images correspond to stop positions. Thermal imaging camera images that correspond to a stop position are retained, while images that do not correspond to a stop position are discarded. Retained images are sent in a video stream to a video processor. The video stream is separated into individual thermal imaging camera images and stored for corresponding virtual camera devices that correspond to specific stop positions. In addition, the position of the camera and individual pixels of images are both correlated to geographical location data, and depth values for the pixels are determined based on the geographical data.

The method includes a step of applying glue including carrying out with a pad printing machine a sequence of steps in which is driven a transfer pad from a glue taking position to an applying position in which the distal surface of the transfer pad is in contact with one surface of one component of the tool and in which is simultaneously driven another transfer pad from a glue taking position to an applying position in which the distal surface of the another transfer pad is in contact with one surface of another component of the tool, whereby the glue is applied simultaneously to the one surface of the one component and to the one surface of the another component.

Disclosed is a method that includes a step of applying glue including carrying out with a pad printing machine a sequence of steps in which is driven a transfer pad from a glue taking position to an applying position in which the distal surface of the transfer pad is in contact with one surface of one component of the tool; and then carrying out again at least once the sequence of steps, whereby the glue is applied at least twice onto the one surface of one component.

The method includes applying glue onto one surface of one component of the tool placed in a support of a first supporting member and/or onto one surface of another component of the tool placed in a support of a second supporting member while the support of the first supporting member and the support of the second supporting member are side by side; then driving the first supporting member and the second supporting member relative to one another to a second position where the support of the first supporting member and the support of the second supporting member are aligned; and then pressing the first supporting member and the second supporting member towards one another for applying onto each other the one surface of the one component and the one surface of the another component.

The invention relates to a method for determining the shape of a bezel (16) of an eyeglass frame rim (11), comprising: a step of acquiring the shape of a longitudinal contour of the bezel, a step of calculating or pointing out a position (.sub.j) of one cross-section (S.sub.j) to be felt along said longitudinal contour, and a step of feeling at least a part of said cross-section (S.sub.j) by moving a mobile feeler in said bezel.

The blocking device includes a blocking portion configured for blocking the semi-finished optical element and including a support member configured for providing a rigid support to the semi-finished optical element, the support member including a support element made of a shape-memory material having a rigid state below a predetermined temperature and a plastic state above the predetermined temperature, the support element assuming in the absence of external forces a predetermined memory shape when heated above the predetermined temperature, the support member having a contact face onto which the first face of the semi-finished optical element is to be applied; saind blocking portion including at least one of a heating device configured for heating the support element above the predetermined temperature and a cooling device configured for cooling the support element below the predetermined temperature.

A method for preparing an ophthalmic lens to be edged based on a presentation lens, includes: fixing a first support a face of the presentation lens, the first support's shape defining a first reference point; positioning the presentation lens by the first support in an optical machine having an image sensor; acquiring, with the image sensor, an image of the presentation lens; determining, on the acquired image, the outline of the presentation lens; positioning a pupillary point relative to the outline; positioning the outline of the presentation lens relative to the ophthalmic lens so the pupillary point is superimposed on a centering point of the ophthalmic lens; and fixing a second support a face of the ophthalmic lens, the second support having a shape defining a second reference point, the second support fixed on the ophthalmic lens so its second reference point is superimposed on the first reference point.

The method includes the steps of: providing spectacles including a template eyeglass having a mounting portion inserted in a groove of an arc and being to be replaced by a prescription eyeglass having a step-back portion with the same conformation as the mounting portion; providing a set of visible marks on the template eyeglass independently of the arc; having an outline editor providing a visualization of the template eyeglass provided with the visible marks; determining through observation of the spectacles the locationwith respect to the visible marksof points of the arc from which the template eyeglass projects; entering on the provided visualization the so determined locations of the points of the arc; and outputting from the editor the data representative of an edited outline based on the point locations so entered on the provided visualization, whereby the edited outline is the outline of the shoulder.

A hydraulic arrangement (HA) for an apparatus (AV) for deblocking optical workpieces (L), from associated block pieces (B), includes a nozzle arrangement (DA) for delivery of high pressure jets of pressure means for deblocking the workpiece from the associated block piece at a first pressure and for cleaning the blocked workpiece and/or block piece at least one second pressure which is different from the first pressure. Furthermore, there is a pump device (PE) which applies pressure in a defined manner to the pressure means and conveys it under pressure to the nozzle arrangement. The pump device has at least one high pressure pump (HP1, HP2) which is drivable by an associated rotary drive (SM1, SM2), the speed of which is modifiable in order to adjust the first pressure or the second pressure.
