Title: Method for production of a pole part of a medium-voltage switching device, as well as the pole part itself
Inventor: CLAUS OLIVER
IPC: H01H33/662
Filed: 2008-09-01
Abstract: The invention relates to a method for production of a pole part of a medium-voltage switching device, and to a pole part itself, as claimed in the preamble of patent claims 1 and 6. In order in this case to ensure that the costly pressure reinforcements are avoided at least on the switching contact side of the vacuum interrupt chamber in the area of the mold core, while nevertheless achieving an optimum injection-molded result, the invention proposes that before the encapsulation process, a compensation ring is positioned as a separate injection-molded seal on or close to the external circumferential line of the vacuum interrupt chamber cover, between the lower cover of the vacuum interrupt chamber and the mold core and then also encapsulated such that it remains as a lost seal in the encapsulation, with the mold core then being removed again.

Title: Optical touchscreen with improved illumination
Inventor: NEWTON JOHN
IPC: G06F3/042
Filed: 2008-08-29
Abstract: In an optical touch display system, light from a primary source can be retroreflected to a detector in the absence of an object in the detection area. When an object is present, its position can be triangulated based on the direction of its shadows at the detectors. Accuracy can be improved with a secondary light source positioned off-axis from the primary light sources so that minimal light from the secondary source is retroreflected to the detectors. Instead, when an object is present, light from the secondary source may be reflected directly from the object. Each detector signal representing light due to the primary light source can be corrected to remove light reflected directly from the object based on identifying and removing a signal component representing light from the secondary light source. In some embodiments, this is facilitated by phasing the primary and secondary light sources.
