  • Patent number: 11666445
    Abstract: An engineered medical device for treatment of osteonecrosis is provided where the size, porosity and ceramic content of the device can be personalized based on an individual patient's anatomical and physiological condition. The device distinguishes different segments mimicking anatomically-relevant cortical and cancellous segments, in which the cortical segments of the device can sustain mechanical loading, and the cancellous segment of the device can promote bone ingrowth, osteogenesis and angiogenesis.

  • Publication number: 20180243982
    Abstract: A simultaneous thermoplastic and thermoset deposition system is provided that includes a substrate holder, a thermoplastic molten-material extruder, photo-polymerizing light source, a prepolymer vat, and a controller, where the controller controls the thermoplastic extruder to deposit a thermoplastic layer according to a thermoplastic pattern on the substrate holder, where the controller controls the substrate holder to immerse the thermoplastic layer in the prepolymer vat for coating the thermoplastic layer with a coating of the prepolymer solution, where the controller controls the substrate holder to position the prepolymer coated thermoplastic layer for exposure to the photo-polymerizing light source, where the controller controls the photo-polymerizing light source to cure the prepolymer coating according to a thermoset pattern on the thermoplastic layer, where the controller iteratively controls the substrate holder, the thermoplastic molten-material extruder, and the photo-polymerizing light source to

  • Patent number: 8443442
    Abstract: A real-time, signature-free, blocker prevents buffer overflow attacks. The system and method, called SigFree, can filter out code injection buffer overflow attack packets targeting at various Internet services such as web services. Motivated by the observation that buffer overflow attacks typically contain executables whereas legitimate client requests never contain executables in most Internet services, SigFree blocks attacks by checking, without any preknowledge of the real attacks, if “executable” instruction sequences can be blindly disassembled and extracted from a packet. Being signature-free, the invention can block new and unknown buffer overflow attacks. It is immunized from almost every attack-side code obfuscation method, and transparent to the servers being protected. The approach is therefore suited to economical Internet-wide deployment with very low deployment and maintenance costs. SigFree can also handle encrypted SSL packets.
