An in vitro biomechanical model used to applied hemodynamic (i.e., blood flow) patterns modeled after the human circulation to human / animal cells in culture. This model replicates hemodynamic flow patterns that are measured directly from the human circulation using non-invasive magnetic resonance imaging and translated to the motor that controls the rotation of the cone. The cone is submerged in fluid (i.e., cell culture media) and brought into close proximity to the surface of the cells that are grown on the plate surface. The rotation of the cone transduces momentum on the fluid and creates time-varying shear stresses on the plate or cellular surface. This model most closely mimics the physiological hemodynamic forces imparted on endothelial cells (cell lining blood vessels) in vivo and overcomes previous flow devices limited in applying more simplified nonphysiological flow patterns. Another aspect of this invention is directed to incorporate a transwell co-cultured dish. This permits two to three or more different cell types to be physically separated within the culture dish environment, while the inner cellular surface is exposed to the simulated hemodynamic flow patterns. Other significant modifications include custom in-flow and out-flow tubing to supply media, drugs, etc. separately and independently to both the inner and outer chambers of the coculture model. External components are used to control for physiological temperature and gas concentration. The physical separation of adherent cells by the artificial transwell membrane and the bottom of the Petri dish permits each cell layer, or surface to be separately isolated for an array of biological analyses (i.e., protein, gene, etc.).

Methods and systems to determine an internal temperature of a rechargeable lithium-ion cell based on a phase shift of the cell. Internal cell temperature may be determined with respect to an internal anode temperature and / or an internal cathode temperature. Internal anode temperature may be determined based on a phase shift of a frequency within a range of approximately 40 Hertz (Hz) to 500 Hz. Internal cathode temperature may be determined based on a phase shift of a frequency of up to approximately 30 Hz. A temperature sensor as disclosed herein may be powered by a monitored cell with relatively little impact on cell charge, may be electrically coupled to cell but housed physically separate from the cell, and / or may monitor multiple cells in a multiplex fashion. A rate of change in phase shift may be used to initiate pre-emptive action, without determining corresponding temperatures.

An input port for a network switch includes a cell buffer for receiving incoming unicast and multicast cells and for writing each cell into an internal cell memory. The cell buffer thereafter forwards each unicast cell from the cell memory to one network switch output port and forwards a separate copy of each multicast cell to each of several network switch output ports. When the cell buffer writes a unicast cell to the cell memory, it sends a pointer to the storage location of the unicast cell to a queue manager. When the cell buffer writes a multicast cell to the cell memory, it sends several pointers to the queue manager, one for each output port that is to receive a copy of the multicast cell, with each pointer pointing not to the multicast cell's storage location but to an empty storage location in the cell memory. The cell buffer also maintains a database relating each pointer it sent to the queue manager to an actual storage location of a unicast or multicast cell. The queue manager queues the pointers an order in which cells are to be forwarded from the cell buffer, and thereafter returns a pointer to the cell buffer whenever the cell buffer is to forward a unicast cell or a copy of a multicast cell from the cell memory. The cell buffer applies each returned pointer to the database to determine the actual location of the unicast or multicast cell to be forwarded.
