Abstract: High-stability electrical connector and interconnection system thereof are provided. An interconnection system includes a receptacle connector and a plug connector. The plug connector includes a latch and a connector position assurance (CPA) device together configured to secure the plug connector to the receptacle connector. The CPA device is configured to be movable to a locked position from a pre-locked position when the plug connector is properly mated with the receptacle connector. At the locked position, the CPA device prevents the latch of the plug connector from disengaging from the receptacle connector. The CPA device includes a body, cantilevers connected to body sides and configured to engage a feature of the plug connector, and elastic arms extending from the body front and configured to abut a feature of the receptacle connector. Techniques described herein enable reliable interconnections in a harsh environment such as one presented by an automobile.

Abstract: A method and a system measure interfering influences on a checkweighing device. In the method, external interference data are obtained, as are interference data from the checkweighing device itself and interference data from an object being weighed, by calculating or mapping the weighing error data in the stationary state, in the operating state, and in the weighing state. The system for measuring the interference uses a meter and a processing apparatus. The meter and the processing apparatus perform an interference measurement and a compensation method. The amount of interference in the checkweighing device in each state and the amount of influence of the interference on the weighing performance is obtained, thereby facilitating the production, debugging, maintenance, and use of a checkweighing device.

Abstract: Arrayed waveguide gratings (AWGs) are important components in coarse wavelength divisional multiplexing (CWDM) and dense wavelength division multiplexing (DWDM). However, the waveguides forming the array must be separated by a distance large enough to suppress parasitic coupling between the adjacent waveguides and thus limiting reductions in device footprint and insertion loss between the input/output coupler regions and the central region comprising the arrayed waveguides. The inventors have established a design methodology allowing the waveguide separation to be reduced whilst limiting cross-coupling thereby allowing for reduced footprints and insertion loss.
