manipulate and control the identified object via an interface unit; and
said interface unit operable to interact with both the processing center and the object.
2. The system according to claim 1, wherein:
the object is one of a visible networked device and a visible un-networked physical object.
3. The system according to claim 2, wherein:
the visible networked device is one of: a video projector, a side or rear flat panel, a front or back room loudspeaker, a television, and an air conditioner.
4. The system according to claim 2, wherein:
the visible un-networked physical object is one of a paper document, a white board, a traditional instruments not connected to any network, and an audio signal recorded by a microphone attached to a mobile device.
5. The system according to claim 1, wherein:
the camera enhanced mobile device is one of a cell phone and a PDA.
6. The system according to claim 1, wherein:
the network is one of Internet and a wireless communication network.
7. The system according to claim 1, wherein:
each of the plurality of features of the object is one of: a Scale Invariant Feature Transform (SIFT) feature, a Gabor feature, a Discrete Cosine Transform (DCT) coefficient, an Optical Character Recognition (OCR) results, and data captured by other sensors on the camera enhanced mobile device.
8. The system according to claim 1, wherein:
the processing center is one of a stand-alone computing unit and an embedded unit in a mobile device or a service center.
9. The system according to claim 1, wherein:
the interface unit has backward compatibility if the object is a traditional device.
10. The system according to claim 1, wherein:
The processing center is operable to manipulate the object by sending a command to the object if the object is on the same network or transforming the command into Infra-Red (IR) signals to control the object.
11. A method to support image based object controlling, comprising:
establishing a database containing features of a plurality of objects;
capturing one or more images of an object via a camera enhanced mobile device and sending the one or more images to a processing center via a network;
extracting a plurality of features of the object from the one or more images captured by the camera enhanced mobile device;
identifying the object the user points to based on the database of object features; and
manipulating and controlling the identified object via commands.
12. The method according to claim 11, further comprising:
defining a plurality of operation rules between the one or more images of the object and its manipulation actions.
13. The method according to claim 11, further comprising:
interacting with the object via an interface unit if the object is a traditional device.
14. The method according to claim 11, further comprising:
manipulating the object by sending a command to the object if the object is on the same network or transforming the command into Infra-Red (IR) signals to control the object.
15. The method according to claim 11, further comprising:
identifying the object in the one or more images via Scale Invariant Feature Transform (SIFT).
16. A non-transitory computer readable storage medium having instructions stored thereon that when executed cause a system to:
establish a database containing features of a plurality of objects;
capture one or more images of an object via a camera enhanced mobile device and send the one or more images to a processing center via a network;
extract a plurality of features of the object from the one or more images captured by the camera enhanced mobile device;
identify the object the user points to based on the database of object features; and
manipulate and control the identified object via commands.
17. A system to support image based object controlling, comprising:
means for establishing a database containing features of a plurality of objects;
means for capturing one or more images of an object via a camera enhanced mobile device and sending the one or more images to a processing center via a network;
means for extracting a plurality of features of the object from the one or more images captured by the camera enhanced mobile device;
means for identifying the object the user points to based on the database of object features; and
means for manipulating and controlling the identified object via commands.
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 dose setting mechanism for a drug delivery device, said mechanism comprising:
an outer body;
an inner body having an external helical groove, said inner body operatively coupled to a driver and guiding said driver to dispense a dose set by said dose setting mechanism; and
a dial sleeve disposed between said outer body and said inner body, said dial sleeve rotatably engaged with said external helical groove of said inner body,
wherein when a dose is set by said dose setting mechanism, said dial sleeve is rotated with respect to both said outer body and said inner body and said dial sleeve is translated away from both said outer body and said inner body,
further comprising a spindle operatively coupled to said driver such that, when said inner body guides said driver to dispense said dose set by said dose setting mechanism, said driver is configured to push said spindle to act on a cartridge bung while said spindle translates in a distal direction to expel said dose from said cartridge; and
wherein said spindle comprises at least first and second helical grooves.
2. The dose setting mechanism of claim 1 wherein said first and said second helical grooves are of opposite handedness.
