Authentication watermarks for printed objects and related applications

The disclosure describes systems for creating and authenticating printed objects using authentication and copy detection watermarks. For example, one verification system includes a watermark decoder and a verification module. The watermark decoder detects a copy detection watermark in a printed object to determine whether the printed object has been reproduced. The verification module processes a message decoded from an authentication watermark on the printed object to authenticate the printed object or bearer of the printed object. The authentication and copy detection watermarks may be implemented as the same or different watermarks. For example, the copy detection watermark may be a fragile watermark that carries the message and that degrades in response to a reproduction operation, such as photocopying or scanning and then reprinting the object. Alternatively, the authentication and copy detection watermarks may be separate watermarks embedded in an image that is printed on the object. The authentication watermark, in some applications, includes an identifier that links the object to a database entry with related information about the object. This related information can be used to check the bearer of the object by comparing it with attributes of the bearer (such as a user ID or photo) or the validity of the object by comparing it with attributes that are visible or machine readable on the object.

Halogen-free expansible flame-retardant thermoplastic resin composition

The invention discloses a halogen-free expansible flame-retardant thermoplastic resin composition, which is prepared by fusing and blending the following components in percentage by weight: 40 to 80 percent of thermoplastic resin, 18 to 25 percent of halogen-free expansible flame retardant, 0 to 5 percent of flame-retardant synergetic agent, 0 to 30 percent of glass fiber, 0 to 2 percent of coupling agent and 0.5 to 1 percent of antioxidant, wherein the thermoplastic resin is any one of polyamide 6, polyamide 66 and polylactic acid or glass fiber reinforced product thereof. The halogen-free expansible flame retardant in the flame-retardant thermoplastic resin composition has low additive amount and good flame retardancy, and the compound flame-retardant synergetic agent does not affect various inherent properties of the resin and can improve the flame retardancy of the material and reduce the cost of the material so as to fill the blank that the prior art has no thermoplastic resin compositions of halogen-free expansible flame-retardant polyamide, polylactic acid and the like.

Tracking and monitoring camera device and remote monitoring system using same

A camera apparatus including a wide area monitoring camera and an intensive monitoring camera as one body. The camera apparatus includes a main frame, a first camera unit and a second camera unit. The main frame has a lens installation surface where a normal line is directed to the lower outside. The first camera unit is installed in the main frame, has a wide angle lens disposed on the lens installation surface so as to direct an optical axis to lower outside and a first image sensor for converting light entering through the wide angle lens into an electrical signal, and photographs images of neighboring areas including an area directly below the camera apparatus. The second camera unit has a second image sensor and is installed so as to rotate horizontally and vertically with respect to the main frame.

Thermal sensing system having a fast response calibration device

PCT No. PCT/GB96/01805 Sec. 371 Date Jan. 9, 1998 Sec. 102(e) Date Jan. 9, 1998 PCT Filed Jul. 29, 1996 PCT Pub. No. WO97/05742 PCT Pub. Date Feb. 13, 1997A thermal sensing system (10) including an array of photon detectors (14) produces a detector-dependent response to irradiation. Variations in individual detector characteristics produce a fixed pattern noise which degrades an image or other response. A switchable mirror (M1) may at one position (Pcal) direct infrared radiation from a light emitting diode (20) onto the detector array (14). The diode (20) is both a negative and positive luminescent emitter, the flux emitted is current controlled to be equivalent to black body radiation at a range of temperatures both colder and hotter than ambient. Calibration relationships comprising transfer functions relating incident intensity to signal response are derived for each detector. Alternatively the mirror (M1) may be at an observation position (Pobs) and infrared radiation from a remote scene reaches the detector array (14). Resulting detector signals are converted into corrected fluxes using individual calibration relationships previously derived and an image or response with reduced fixed pattern noise is obtained.
