Title: Lockstep mechanism to ensure security in hardware at power-up
Inventor: KITARIEV DIMITRI
IPC: G01R31/3185
Filed: 2005-06-28
Abstract: A system and method of ensuring hardware security of a device, such as an integrated circuit having secure data stored thereon. The integrated circuit or other hardware device can implement one or more configurable fuses that limit access to one or more secure locations within the device. The secure locations may contain secure data. The state of the configurable fuses can be ensured, thereby limiting access to secure locations, by forcing the occurrence of a logical state prior to allowing access to hardware locations configured by the fuses. A configurable non-secure access code can be used to force the occurrence of the logical state. Receipt of the non-secure access code by the hardware device forces the occurrence of the hardware state, thereby ensuring access only to those secure locations configured by the fuses.

Title: Optical planar wavelength selective filter and method of manufacture
Inventor: RIESTER MARKUS
IPC: H01S3/08
Filed: 2007-10-04
Abstract: An optical planar wavelength selective filter (100) is formed on a printed circuit substrate (110). Low optical loss polymers are used to make a layered structure that contains waveguides and free travel zones (240). A diffraction grating (270) is strategically placed on the printed circuit substrate (110) so that light from one waveguide (232) is diffracted by the grating to exit the free travel zone (240) and pass through the other waveguides (234, 236, 238). The low optical loss polymer is a reaction product of the hydrolysis and polycondensation reaction of organically functionalized alkoxysilanes. With a proper grating, the apparatus can be used as an optical triplexer at frequencies of 1310, 1490, and 1550 nanometers. ® KIPO & WIPO 2009

Title: Audio dynamics processing using a reset
Inventor: SEEFELDT ALAN JEFFREY
IPC: G10L21/0364
Filed: 2007-09-25
Abstract: An audio dynamics processor or processing method that uses a reset mechanism or process in order to adapt quickly to content changes in the audio signal. A reset signal may be generated by analyzing the audio signal itself or the reset may be triggered from an external event such as a channel change on a television set or an input selection change on an audio/visual receiver. In the case of an external trigger, one or more indicators of the state of the dynamics processor for a current audio source may be saved and associated with that audio source before switching to a new audio source. Then, if the system switches back to the first audio source, the dynamics processor may be reset to the state previously stored or an approximation thereof.

Title: Estimating position of stuck-at defect in scan chain of device under test
Inventor: BURLISON PHILLIP D
IPC: G06F11/22
Filed: 2008-02-28
Abstract: As a scan pattern is shifted out of a scan chain, the scan pattern is evaluated in real-time for the existence of a logic condition. A reference to a portion of the scan pattern that is currently being evaluated is maintained. Upon identifying the existence of the logic condition when the reference has a predetermined relationship to a stored value, the stored value is overwritten using the reference. The stored value is then used to estimate the position of a stuck-at defect in the scan chain.

Title: Method and apparatus for mura detection and metrology
Inventor: SANDSTROM TORBJOERN
IPC: G02F1/13
Filed: 2008-04-18
Abstract: The invention devices an inspection method, e.g. optical, which maximizes the sensitivity to mura effects and suppresses artifacts from the mura inspection hardware itself and from noise. It does so by scanning the sensor, e.g. a high-resolution camera, creating a region of high internal accuracy across the mura effects. One important example is for mura related to placement errors, where a stage with better than 10 nanometer precision within a 100 mm range is created. A sampling scheme reduces the data volume and separates between instrument errors and real defects based on their different geometrical signatures. The high-resolution camera scans sparse lines at an angle to the dominating directions of expected mura defects, creating extended sensor fields with high internal precision, and quantifying edge placements in small windows in said extended fields. The mura is classified and presented as type, location and severity.
