Abstract: An optical detection device includes a first linear light source, a second linear light source, an optical sensor array and a processor. The first linear light source is adapted to project a first long strip illumination beam onto the target container. The second linear light source is adapted to project a second long strip illumination beam onto the target container, and the second long strip illumination beam is crossed with the first long strip illumination beam. The optical sensor array is adapted to receive a first long strip detection beam and a second long strip detection beam reflected from the target container. The processor is electrically connected to the optical sensor array. The processor is adapted to analyze intensity distribution of the first long strip detection beam and the second long strip detection beam to acquire a relative distance between the optical sensor array and the target container.

Abstract: An adjustable modular doorframe includes a first jaw member secured on a first (or inner) side surface of a wall, and a second jaw member telescopically engageable with the first jaw member to accommodate the wall thickness and then secured to a second side (or outer) surface of the wall, thereby forming a doorframe for adjustably optionally meeting the variable thickness of the wall.

Abstract: A knockdown doorframe includes: a pair or jambs respectively secured to a right and a left vertical side wall of a doorway, each jamb having an adjustable covering plate adjustably shielding a side portion of the jamb with the wall; and a lintel horizontally secured to a top portion of each jamb adjacent to a horizontal top wall of the doorway and having an adjustable horizontal covering plate adjustably shielding an upper portion of the lintel and the horizontal top wall, whereby upon a sliding or telescopic movement of each covering plate in each jamb or in the lintel, the covering plate may adjustably well shield the jamb or lintel with the wall having variable wall thickness for security and ornamental purposes.

Abstract: A knockdown doorframe includes: a pair of jambs (1) respectively secured on a right and left vertical side wall (V) of a door entrance or doorway (O) by means of brackets (2) longitudinally pre-fixed on the right and left vertical side walls (V), each jamb (1) having a waterproof pad (3) cushioned on a bottom of the jamb (1), a lintel (4) horizontally secured on the top portion of each jamb (1) adjacent to a horizontal top wall (H) of the doorway to form an inversed U-shaped doorframe, and each jamb (1) and lintel (4) having a covering plate (5, 5a) covered thereon for shielding an aperture (A) between the doorframe and the wall (V, H) of the doorway (O) for decorative purpose.

Abstract: An imitated carved wooden door includes: a plastic leather imitating a wooden surface having three-dimensional recess and extending portions formed therein by an integral molding process, a lining core body reinforced in the surface plastic leather retained in a supporting framework, wherein the lining core body may be pre-formed by a molding process having three-dimensional recess and extending portions engageable with the recess and extending portions of the surface plastic leather so as to form an imitated carved wooden door having a more vivid three dimensional structure approaching a real carved wooden door.
