Abstract: A wireless router applying an antenna control method includes a number of antennas and communicates with a number of terminal devices via the antennas. The antenna control method includes detecting a current bandwidth Bcur of each terminal device communicating with the wireless router and determining a maximum bandwidth Bmax of each of the terminal devices, computing a weighted sum SUMB of the bandwidths of the terminal devices according to the detected current bandwidth Bcur and the maximum bandwidth Bmax of each terminal device, comparing the weighted sum SUMB of the bandwidths with a first preset value, and turning on or turning off at least one of the antennas according to the compared result. A wireless router is also provided.

Abstract: Provided herein is technology relating to cryopreservation and particularly, but not exclusively, to devices, systems, and methods for cryopreservation of biological materials such as oocytes, zygotes, and embryos.

Abstract: Disclosed is a self-expanding cannula, systems using such cannulae, and methods of their use. The cannulae may comprise single lumen cannula (SLC) configurations and double lumen cannula (DLC) configurations, and include at least a first cannula and a self-expanding wire frame attached to the first cannula. Self-expanding wire frame is automatically expandable from a compressed state (providing a reduced cannula diameter as it is moved through a patients body to the site at which it is to be deployed) to an expanded state (which increases the diameter of the cannula to the diameter intended for its normal use). The expanded wire frame provides radial support to prevent a drainage canal (whether a patients blood vessel or a portion of the system inserted into the patients blood vessel) from collapsing as fluid is drained from the patient.

Abstract: A probe suitable for deep-brain recording and stimulation is provided. The probe comprises a wire bundle that includes a plurality of wires, an integrated circuit having a plurality of electrodes, and an interposer that joins the wire bundle and the integrated circuit such that each of the plurality of electrodes is electrically connected with a different wire of the plurality of wires.

Abstract: Disclosed are flashlights that optimize the light output and beam focus of both a flood beam and a spot beam. The disclosed flashlights include a housing member and a lens including a first focusing element adapted to shape a light beam into a spot beam and a second focusing element adapted to shape a light beam into a flood beam. A first LED is positioned to direct light through the first focusing element, and a second LED positioned to direct light through the second focusing element. The first LED has a smaller die than the second LED, and the distance between the first LED and the first focusing element is greater than the distance between the second LED and the second focusing element.

Abstract: The present invention provides methods and compositions for establishing and maintaining growth of undifferentiated stem cells. In particular, the present invention provides synthetic growth matrices for stem cells, wherein said cells are capable of going through multiple passages while remaining in an undifferentiated state.
