  • Patent number: 12261723
    Abstract: Systems and methods relating to estimating data symbols encoded in a received signal that has been transmitted at a faster than Nyquist rate. The present invention uses a heuristic method for non-convex problems and involves an input matrix and received samples from the received signal. These are preconditioned and the preconditioned input matrix is factorized. The method then iterates a three-step process that estimates the sequence of data symbols based on the current estimate, the preconditioned input matrix, the preconditioned samples vector, a multiplier vector, and an auxiliary vector. The process then calculates the next multiplier vector and the next auxiliary vector. If the result indicates a minimum as compared to the best estimate, then the result is used as the best estimate. Multiple iterations of the process are performed, and the multiple iterations are repeated for multiple random initializations of the estimate.

  • Patent number: 11517696
    Abstract: Novel airway devices and methods address complications of ventilating a patient with a mask; placing an endotracheal tube in an awake patient; and need for a bite block during flexible bronchoscopy and gastroscopy. The airway device features notches for engaging maxillary and mandibular teeth in a manner protracting the patient's mandible relative to the maxilla to open up the airway. This way, an open airway is easily maintained simply by holding the jaw closed against the device with the same hand used to operate a bag ventilator. A longitudinal channel in the device features a downwardly curved end wall for improved guidance of the endoscope into position. The channel is open sided at the top or bottom to allow rolling of the airway device off the endoscope into an offset position serving as a protective bite block and allowing feeding of the endotracheal tube along the endoscope.

  • Patent number: 11124575
    Abstract: An Epidermal Growth Factor Receptor (EGFR, HER1, ErbB1)-binding agent has a heavy chain and a light chain, wherein the dimerization loop from EGFR's Domain II is grafted within complementarity determining region 3 (CDR3) of the heavy chain, and the binding agent is affinity matured. The graft directs the binding agent to bind EGFR at its dimerization region, to thereby inhibit EGFR dimerization and activation. In another embodiment, an EGFR-binding agent is panned out of Library F, a Fab library. The binding agents are for detecting and/or quantifying EGFR expression, for targeting EGFR-expressing cells, and for decreasing levels of EGFR in EGFR-expressing cells.
