  • Patent number: 12249334
    Abstract: A text mining engine running on an artificial platform is trained to perform conversation role identification, semantic analysis, summarization, language detection, etc. The text mining engine analyzes words in a transcript that represent unique characteristics of a conversation and, based on the unique characteristics and utilizing classification predictive modeling, determines a conversation role for each participant of the conversation and metadata describing the conversation such as tonality of words spoken by a participant in a particular conversation role. Outputs from the text mining engine are indexed and useful for various purposes. For instance, because the system can identify which speaker in a customer service call is likely an agent and which speaker is likely a customer, words spoken by the agent can be analyzed for compliance reasons, training agents, providing quality assurance for improving customer service, providing feedback to improve the performance of the text mining engine, etc.

  • Publication number: 20230213726
    Abstract: Disclosed herein is metasurface modules configured to reduce the cost of integration of metasurface elements within a housing and methods of manufacturing thereof. One particular embodiment includes a metasurface module including: a secondary substrate; and a metasurface chip mounted on the secondary substrate. The secondary substrate laterally extends from all sides of the metasurface chip to completely surround the metasurface chip. The secondary substrate may be utilized to mount the metasurface chip within a housing which decreases the size of the metasurface chip and ultimately decreases manufacturing costs of the metasurface chip.

  • Publication number: 20220385042
    Abstract: Disclosed herein are single element dot pattern projectors with a meta-optics. The projectors include a laser light source and a metasurface chip integrated onto the laser light source. The metasurface chip includes metasurface elements spaced apart from the laser light source by a distance equal to the collimating function focal length of the metasurface chip. the laser light source produces light which is diffracted through the metasurface elements to produce a dot pattern. Projectors enabled by meta-optics lead to unique methods of integrating the meta-optic and unique functionality that can be added to the dot pattern.

  • Patent number: 9298844
    Abstract: A system and method for optimizing mobile communications with one or more message recipients is disclosed. The system is configured to create a unique URL and send it to a message recipient via an appropriate communication platform. The system waits for the unique URL to be requested and logs information from the web browser associated with the mobile communication device used to access the unique URL. The system may use this information to direct the mobile device user to a dynamically created web page. This methodology can be used to improve immediate and future communications by tailoring the message content and communication platform according to the message recipient's mobile device. The dynamic web page may also be configured to prompt the message recipient to execute a desired action, including downloading a compatible mobile app and changing message delivery preferences in order to optimize communications with the message recipient.

  • Patent number: 9190548
    Abstract: An improved method of fabricating an interdigitated back contact (IBC) solar cell is disclosed. A first mask is used to perform a patterned ion implantation of n-type dopant to create the back surface field. A second mask is then used to create the p-type emitter on the same surface. The second mask may be aligned to the n-type implant, and may be used in a plurality of orientations to create the desired p-type emitter. In some embodiments, a p-type blanket implant is performed as well. In some embodiments, a doping gradient is created.
