1. A three-dimensional (3D) spectacle structure and management system therefore, comprising:
a plurality of 3D spectacles, each pair of 3D spectacles includes: a frame, a pair of lenses mounted in the frame, and a pair of temples extending in a rearward direction from opposite sides of the frame; and
an RFID (Radio Frequency Identification) chip, mounted to a predetermined location on one of the frame or a temple, the RFID chip providing an individual and unique identification for the pair of spectacles;
at least one first RFID reader disposed in proximity to an entrance to a movie theater, the first RFID reader configured to detect the RFID chip in each pair of 3D spectacles that pass through the movie theater entrance and configured to transmit the unique identifications associated therewith to a database to change a status thereof for indicating those corresponding pairs of 3D spectacles as being in use;
at least one first display device disposed in proximity to the entrance to the movie theater, the first display device configured to display a prior status of each pair of 3D spectacles detected by the first RFID reader for confirmation to a user of the pair of 3D spectacles;
at least one photographing device disposed in proximity to the entrance to the movie theater, the photographing device configured to photograph a user of an individual pair of 3D spectacles responsive to the first detecting the RFID chip corresponding to the individual pair of 3D spectacles;
at least one second RFID reader disposed in proximity to an exit to the movie theater, the second RFID reader configured to detect the RFID chip in each pair of 3D spectacles that pass through the movie theater exit and configured to transmit the unique identifications associated therewith to the database to change a status thereof for indicating those corresponding pairs of 3D spectacles as being in returned; and
at least one second display device disposed in proximity to the exit to the movie theater, the second display device configured to display the changed status of each pair of 3D spectacles detected by the second RFID reader for confirming the returned status to a user.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A container for holding a saw blade of a reciprocating saw, wherein the saw blade having a set of teeth extended out of two side faces thereof, comprising:
a separate body having an engaging portion,
a cover operable to engage with the engaging portion of the body to form a chamber for receiving the saw blade.
2. The container as set forth in claim 1, wherein the cover is connected to the body through a hinge.
3. The container as set forth in claim 1, wherein the cover is sliding mounted on the body.
4. The container as set forth in claim 1, wherein the cover can be plugged onto the body.
5. The container as set forth in claim 1, wherein the cover and the body each comprises a locking device.
6. The container as set forth in claim 1, wherein one of the cover and the body comprises a fastener for fastening to clothing of an operator.
7. The container as set forth in claim 1, wherein at least a part of the body is transparent.
8. The container as set forth in claim 1, wherein the body is elongate.
9. A storage case for holding a plurality of saw blade containers of claim 1, the storage case comprising:
a first shell, and
a second shell,
wherein the first shell and the second shell is engageable with each other, and at least one of the first shell and the second shell comprises a set of receiving slots, each receiving slot being operable for receiving a container.
10. The storage case as set forth in claim 9, further comprising a set of release slots, each release slot being perpendicular to and communicating with one of the receiving slots.
11. The storage device as set forth in claim 9, wherein an elastic member is defined on at least a lateral side of the receiving slot.
12. A storage case for holding a plurality of saw blade containers, the storage case comprising:
a first shell hingeably connected to a second shell;
one of either the first or second shell having;
a plurality of receiving slots, each receiving slot having a bottom surface and two lateral opposed sides and an elastic stopper extending from at least one of the lateral sides, the bottom surface of the receiving slot residing in a first horizontal plane with respect to a reference surface; and
a plurality of release slots, each one of the release slots corresponding to one of the receiving slots and having a bottom surface that resides in a different horizontal plane than the horizontal plane of the bottom surface of the corresponding receiving slot.
