Title: System for transitioning telephony-based and in-person servicing interactions to and from an artificial intelligence (AI) chat session
Inventor: Scott Karp
IPC: H04M3/51
Filed: 2020-05-22
Abstract: Input data from an unauthenticated user is received which indicates a servicing intent. A servicing intent token based on the input data is then generated. A call to an AI chatbot model is performed and the generated servicing intent token is transmitted to the AI chatbot model. The servicing intent token is mapped to a stored servicing intent token from a plurality of stored servicing intents. A request for personally identifiable information associated with the unauthenticated user from the user device is transmitted via an AI chat session. The personally identifiable information is received via the AI chat session. It is determined whether the supplied personally identifiable information can be used to successfully identify the unauthenticated user wherein, if the determination is made that the supplied personally identifiable information can be used to successfully identify the unauthenticated user then the unauthenticated user is authenticated using the personally identifiable information. However, if the determination is made that the supplied personally identifiable information cannot be used to successfully identify the unauthenticated user, further personally identifiable information is requested until a determination can be made that the supplied personally identifiable information can be used to successfully identify the unauthenticated user.

Title: Systems and methods for immobilizing extracellular matrix material on organ on chip, multilayer microfluidics microdevices, and three-dimensional cell culture
Inventor: DONGEUN HUH
IPC: A61L27/38
Filed: 2016-07-27
Abstract: A method of shaping the geometry of living tissues in vitro comprising selecting one or more substrates for tissue growth, identifying desired tissue anchorage points on the one or more substrates, and coating the selected substrates with a heterobifunctional crosslinker at the identified desired tissue anchorage points. The heterobifunctional crosslinker is cured to the substrate, and extracellular matric (ECM) gel layer embedded with a contractile tissue is added. The cell-mediated contractile forces shape the tissue geometry as the gel layer contracts between the fixed anchorage points. Preferably the substrate is polydimethylsiloxane (PDMS) and the heterobifunctional crosslinker is N-sulfosuccinimidyl-6-(4’-azido-2’- nitro-phenylamino)hexanoate (sulpho-SANPAH). The ECM gel layer may comprise extracellular matrix proteins selected from collagen, fibronectin, laminin and/or hyaluronic acid.

Title: Pipelined hardware to accelerate modular arithmetic operations
Inventor: RAJAT RAO
IPC: G06F7/575
Filed: 2022-03-22
Abstract: The pipelined hardware is directed to elliptic curve cryptography scalar multiplications in a generic field with heavy pipelining between field operations. A bit width is determined of operands in data to be processed by a modular hardware block. It is checked whether the bit width of the operands matches a fixed bit width of the modular hardware block. In response to there being a match, the modular hardware block processes the operands. In response to there being a mismatch, the operands are modified to be accommodated by the fixed bit width of the modular hardware block.

A specific application of the system is for accomplishing reflow soldering of surface mount devices to printed circuit boards.
Patent KR-860006287-A (KR)
IPC: B05C3/02
Filed: 1986-02-27
Abstract: Method and apparatus for coating catalytic converter substrates with an exact amount of a precious metal. In the course of operation of the apparatus, a hollow substrate to be treated having opposed open ends is transferred from a starting location such that one end is lowered into a dip pan into which has been introduced a predetermined amount of slurry material containing the precious metal. With the one end immersed in the slurry, a vacuum placed on the other end of the substrate draws up the entire charge of slurry from the dip pan to coat the lower portion of the substrate. Thereafter, the substrate is raised from the dip pan. The vacuum continues to operate to cause the coating to be evenly distributed on all the interior surfaces of the substrate. Then the substrate is rotated and again lowered so that the other end is immersed in another predetermined charge of the slurry and the process is repeated. Thereupon, the substrate is again raised from the dip pan. Again, the vacuum continues to operate for a predetermined period of time to assure even distribution of the coating. Then the substrate is again rotated to its original orientation, and returned to its starting location.

Abstract: In a process for producing an injection molded product, a stream of plastic material is introduced into a mold space 11 at a first pressure. Gas is stored in a storage chamber 28 at a second pressure which is at least as high as the first pressure. The gas is introduced into the molten stream of plastic material immediately after the molten material has passed the position at which the gas is introduced thereby forming a gas cavity in the molten material. The gas exerts pressure on the surrounding plastic material to urge the material toward the surfaces of the mold space. As the feeding of the plastic material into the mold space continues, the injection of the gas is also continued. The supply of molten material is terminated when the surfaces of the mold space are completely covered by the molten material. A pressure is held within the gas cavity as the plastic material cools. Subsequently, the pressure is released to bring the gas cavity to ambient pressure. The the mold 9, 10 is opened to remove the hollow shaped article. An apparatus for producing an injection molded product is also disclosed.

Abstract: PCT No. PCT/EP88/00259 Sec. 371 Date Oct. 27, 1989 Sec. 102(e) Date Oct. 27, 1989 PCT Filed Mar. 29, 1988 PCT Pub. No. WO88/07799 PCT Pub. Date Oct. 6, 1988.A line deflection circuit for a picture tube, for generating a symmetric deflection current in a deflection or sweeping coil and a tangential capacitor comprises: an active switch for supplying a near square wave shaped output voltage to one end of the deflection coil, at half line frequency and at a keying ratio of 1:1; and, an amplifier having an output coupled to the other end of the deflection coil and having a control input responsive to at least one of first and second corrective variables to assure linearity of a deflection current flowing through the deflection coil and line centered zero crossing of the detection current. The first corrective variable is proportional to the deflection current through the deflection coil and the second corrective variable is related to a deviation of the output of the switch from the square wave shape. The circuit may also comprise a timing comparator for determining each zero crossing relative to immediately preceding and following edges of the output voltage. A control potential may be derived therefrom for controlling a gain factor of the amplifier. The active switch may comprise a potential divider.

Abstract: This invention relates to business communication systems and, in particular, to a message service system network that interconnects a plurality of message service systems and provides a voice mail message transfer capability between voice mail message service systems. The voice mail message transfer is performed as a computer-to-computer data file transfer operation over high speed data lines. The data file consists of the digitally encoded and compressed voice mail message to which is appended the message sender's name and telephone number as well as the message recipient's telephone number.
