Patent number: 11339362Abstract: Disclosed herein are various bioreactor devices that mimic the mammalian joint. The bioreactor device can include a series of bioreactor chambers that contain different components of the joint, such as bone, cartilage, synovium, nerve and ligament. At least two different nutrient fluid circulation systems connect subsets of the bioreactor chambers to differentially supply nutrient fluids at concentrations optimized for the tissue that the fluid nourishes. For example, relatively hypoxic fluid can be supplied to synovium and cartilage to mimic oxygenation in the joint compartment, but normoxic fluid can be supplied to the bone and other components that have an arterial supply that provides higher oxygen concentrations. One or more or all of the bioreactor chambers can be supplied with separate inlets through which perturbation agents (such as drugs or other agents) can be introduced to model the effect of the perturbations on different components of the system.Type: GrantFiled: November 16, 2018Date of Patent: May 24, 2022Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Hang Lin, Peter Alexander, Riccardo Lucca Gottardi, Rocky Sung Chi Tuan

Patent number: 11337027Abstract: A wireless mesh network comprises a controller and a plurality of wireless networked devices arranged to transmit messages to and receive messages from the controller. The plurality of devices are arranged in zones, such that a device that is arranged to communicate directly with the controller is designated a “Zone 1” device and a device that is arranged to communicate with the controller via a “Zone 1” device is designated a “Zone 2” device. One or more or each of the plurality of devices periodically sends a positioning message to the controller to determine its zone and if it can communicate directly with the controller it determines that it is a “Zone 1” device and if it cannot communicate directly with the controller, but it can communicate with the controller via a “Zone 1” device and therefore arranged to do so, it determines that it is a “Zone 2” device.Type: GrantFiled: September 3, 2018Date of Patent: May 17, 2022Assignee: TEXECOM LIMITEDInventors: Peter Alexander, Clym Brown

Patent number: 10848200Abstract: A mesh network comprises a controller and a plurality of mesh-networked devices, operable to communicate with the controller. The controller and the plurality of mesh-networked devices comprise timing units, and are operable to communicate in accordance with a frequency hopping sequence. The mesh-networked devices switch between a transmit mode, in which they are capable of transmitting messages to one or more other mesh-networked device and/or the controller and an inactive mode, in which they are unable to transmit to or receive messages from one or more other mesh-networked devices or the controller. The timing units of the mesh-networked devices are synchronised and the mesh-networked devices are operable to switch to the transmit mode at pseudorandom time intervals.Type: GrantFiled: December 19, 2017Date of Patent: November 24, 2020Assignee: TEXECOM LIMITEDInventor: Peter Alexander
