  • Patent number: 11388044
    Abstract: A computer-program product, a system, and a computer-implemented method include a processor(s) obtaining a configuration of a network including configurations of multiple network nodes and configurations of the network communication devices. The program code automatically models the network to generate a system model. The program code derives, from the system model, a loop-free Bayesian inference model, by generating a loop-free Bayesian network from the network.

  • Patent number: 10684118
    Abstract: An apparatus for determining an orientation of a die mounted on a tape includes an imaging device, a light source and a conveying mechanism. The die is at least partially translucent and includes at least one orientation feature indicative of the orientation of the die. In use, the conveying mechanism conveys the tape to position the die at an inspection position between the imaging device and the light source. The light source projects light to the imaging device and the imaging device captures an image. The projected light from the light source passing through the die is obstructed by the at least one orientation feature of the die to cause the captured image to include an image of the at least one orientation feature, whereby the orientation of the die may be determined.

  • Patent number: 10288979
    Abstract: The present disclosure describes the design and fabrication of a Terahertz (THz) beam steering device and a multifunctional patternless flat lens using electro-optic tunable fishnet materials (TFMM) to create a portable THz imaging system. The THz beam steering device and multifunctional patternless flat lens utilize a tunable resonant frequency of TFMM (with a negative refraction index) to achieve a maximum beam steering angle (field of view) and beam modulation. The portable THz scanning system is made by combining the TFMM beam steering device with a pair of continuous wave (CW) photomixer modules powered by two tunable CW lasers with built-in optical isolators, a fiber-optic beam combination and a multifunctional flat lens.

  • Publication number: 20140370834
    Abstract: Methods and systems for disabling supplementary services that interfere with callback from a public safety answering point are described. In one embodiment, a method is performed by a system operating in a home network domain of a wireless network. The home network domain includes a home subscriber server (HSS) which maintains user profiles associated with a plurality of communication devices. The user profiles define services enabled for such communication devices. The method includes: detecting an emergency registration associated with an emergency call placed from the communication device; and in response to detecting the emergency registration associated with the emergency call, updating, at the HSS, the user profile associated with the communication device which placed the emergency call to disable at least one supplementary service for that communication device.
