  • End cap arrangements for composite door assembly
    Patent number: 11131139
    Abstract: A Dutch door assembly includes first and second door sections, each including a composite door member and an end cap. The composite door member includes a core member disposed between first and second end stiles, together defining a front door surface, a rear door surface, and an end surface, a front door skin secured to and substantially covering the front door surface, and a rear door skin secured to and substantially covering the rear door surface. The end cap includes a cover portion covering the end surface of the composite door member and a retention portion extending from the cover portion into engagement with the core member. The end cap of the first door section includes an abutment portion contoured to engage an abutment portion of the end cap of the second door section when the first and second door sections are in pivoted alignment.

  • Rotary angle sensing system
    Patent number: 7456629
    Abstract: The present invention includes a rotary sensing system that includes a shaft, a magnet encircling the shaft, a pair of plates, each of which is positioned near distal ends of the magnet, and at least one sensing device. The magnet generates a magnetic field, the angle of which changes as the shaft rotates. The pair of plates directs the magnetic field generated by the magnet towards the at least one sensing device. The at least one sensing device is sensitive to the changes in the angle of the magnetic field, which are indicative of an angular position of the shaft.
