Patent number: 9921262Abstract: An integrated apparatus and method to provide test, diagnostics and characterization access to backplane electrical signals during electronic product development is presented. The apparatus removes need for manual and ad hoc connections made in an engineering laboratory or assembly line which make the process prone to damage of the components, inaccurate measurements and arbitrary fluctuations in function. The method and apparatus is a mechanized way to connect backplane signals to corresponding drivers, receivers and test equipment through probes placed on equidistant electrical traces, reducing inter signal variations.Type: GrantFiled: April 7, 2015Date of Patent: March 20, 2018Assignee: Elma Electronic Inc.Inventors: Walter A Schindler, Jerry Choy

Patent number: 6177631Abstract: The figures show module carriers with one straight and one angled sheet metal cover (1, 2) which form an angle connection for a housing. Hooks (3) are bent out from the straight sheet metal lamina (1) on the inner side in order therein to receive a limb (4) of the angled sheet metal lamina (2). Elastic contact springs are formed on the hooks in order to produce a predetermined contact force on the inserted limb. The thickness of the sheet metal lamina and the dimensions of the contact springs and the hooks are matched to one another in such a manner that the hooks can be accommodated within a distance 1<16 mm from an edge (5) of the straight sheet metal lamina (1).Type: GrantFiled: July 22, 1998Date of Patent: January 23, 2001Assignee: ELMA Electronics AGInventor: Walter A. Schindler

Patent number: 6054650Abstract: With the invention, for a module carrier, combinations are shown of sheet metal covers with a longitudinal section which has a through-going slit for the insertion of an edge of a sheet metal cover. Since the edge is interrupted by slits or cut-outs in order to form resilient tongues and the tongues bordering on a slit have an oppositely protruding contact knob, the tongues can be provided with a bias stress when being inserted and produce a contact and holding force.Type: GrantFiled: April 23, 1998Date of Patent: April 25, 2000Assignee: Elma Electronic AGInventor: Walter A. Schindler

Patent number: 4902239Abstract: The manipulator for pushing plug connectors of a plug board out of engagement with spring strips of a component support has a lug for engaging a plug-in surface of the support in order to engage the plug connectors with the spring strips. The same manipulator is used not only for unplugging the connectors but also for establishing a connection between the plug connectors and the spring strips.Type: GrantFiled: June 8, 1988Date of Patent: February 20, 1990Assignee: Elma Electronic AGInventor: Walter A. Schindler

Patent number: 4344595Abstract: An auxiliary apparatus at a stand for an optical observation device, such as a surgical microscope is disclosed, which contains a stand at which there is mounted the surgical microscope. The stand comprises a number of rotary and brake bearings, a support arm and a pivotal arm as well as a hinge parallelogram. The surgical microscope or other instrument can be freely adjustable, but fixed in position, throughout a predetermined spatial region as concerns its position and orientation. Arranged at the parallelogram is a web or strap for mounting a support element, at which there is laterally arranged a holder for the attachment of the housing of a brake bearing and a head element. In the head element there is movably mounted by means of a ball hinge element a coupling element structured for receiving and attaching the surgical microscope.Type: GrantFiled: July 10, 1980Date of Patent: August 17, 1982Assignee: Contraves AGInventors: Rudolf Heller, Walter Schindler

Patent number: 4339100Abstract: An arrangement at a stand for an optical observation device, especially for a surgical microscope, containing a stand which essentially comprises an upright column or stand at which there is pivotably mounted an arm member for pivotable movement about a horizontal axis. There are further provided a support arm, a number of rotary and brake bearings and a hinge parallelogram at which there is suspended the microscope or the like. At one end of the arm member or arm there is arranged a guide lever and at the other end a weighting disk as well as a brake bearing at which there is secured a rod carrying a counterweight. The guide lever and the rod are operatively connected with one another by means of a thrust rod extending parallel to the arm member. This arm member is arrestable and positionably fixable at the stand column by means of a bolt member insertable into the weighting disk and radially penetrating the column body.Type: GrantFiled: July 10, 1980Date of Patent: July 13, 1982Assignee: Contraves AGInventors: Rudolf Heller, Walter Schindler
