Patent number: 11213667Abstract: A 3D printed biocompatible drug delivery device is provided having a fluid delivery channel distinguishing three segments and a receiving chamber with an array of microneedles. The three segments of the delivery channel are stagnation zones before a drug is extruded and whereby an inverted funnel provides an increasing extrusion surface servicing the drug to the array of microneedles. The design of the device with its flow-related components circumvents the challenge of colloidal stability associated with multi-phase formulations leading to nozzle blockage. Qualitative screening cytotoxicity tests pre and post-extrusion through the drug delivery device using mammalian cells rule out cytotoxicity and outline equivalent viability to control treatments. The biocompatibility results suggest that the fluid delivery design, the photoresin selected as well as the fabrication and sterilization may be extended over a range of regenerative medicine and drug delivery applications.Type: GrantFiled: July 11, 2019Date of Patent: January 4, 2022Assignee: Santa Clara UniversityInventors: Maryam Mobed-Miremadi, Chantell Farias, Cecilia Hemingway, Roman Lyman

Patent number: 10758486Abstract: Vesicular stomatitis virus glycoprotein (VSVG) can both load protein cargo onto exosomes and increase their delivery ability via a pseudotyping mechanism. By fusing a set of fluorescent and luminescent reporters with VSVG, we show the successful targeting and incorporation of VSVG fusions into exosomes by gene transfection and fluorescence tracking. VSVG pseudotyping of exosomes does not affect the size or distributions of the exosomes, and both the full-length VSVG and the VSVG without the ectodomain integrate into the exosomal membrane, suggesting that the ectodomain is not required for protein loading. Finally, exosomes pseudotyped with full-length VSVG are internalized by multiple-recipient cell types to a greater degree compared to exosomes loaded with VSVG without the ectodomain, confirming a role of the ectodomain in cell tropism.Type: GrantFiled: July 12, 2018Date of Patent: September 1, 2020Assignee: Santa Clara UniversityInventors: Biao Lu, Conary Meyer, Joseph Losacco, Zachary Stickney

Patent number: 10451294Abstract: Smart hot water heater control can be improved by departing from the conventional approach of monitoring hot water demand at a single point (i.e., the water heater output). Instead, hot water demand is monitored at each location in the building where hot water is used. With this approach, the controller can provide hot water at a temperature suitable for the intended use, e.g., warm water for a bath or shower, and much hotter water for a dishwasher. This advantageously avoids inefficiency due to mixing hot and cold water at a tap to provide temperature control.Type: GrantFiled: July 14, 2015Date of Patent: October 22, 2019Assignee: Santa Clara UniversityInventors: Hohyun Lee, Russell Williams, Rachel Donohoe, Rebecca Barney, Kerbasi Ugarte, Xavier Moya, Alex Zatopa

Patent number: 10326995Abstract: System and method embodiments are provided for achieving improved View Synthesis Distortion (VSD) calculation and more accurate distortion estimation of encoded video frames. An embodiment method includes obtaining a depth map value for a video frame and determining a weighting factor for depth distortion in accordance with the depth map value.
