20120240344 | WASHING MACHINE FOR AUTO-ADDED WASHING AGENT BY NEGATIVE PRESSURE AND CONTROLLING METHOD THEREOF - A washing machine for automatically adding the detergent by negative pressure comprises a water inlet, a detergent container and a tub. A main inflow waterway and a rinse waterway are provided between the water inlet and the tub. A dosing container which communicates with the detergent container is provided between the rinse waterway and the tub. A venturi tube is provided in the main inflow waterway. Due to venturi effect, the main inflow water stream becomes narrower and the water inflowing velocity is accelerated, so that a relative vacuum area which communicates with the dosing container is formed at the rear side of the venturi tube outlet, negative pressure is generated in the dosing container, and the detergent in the detergent container. | 09-27-2012 |

20130125832 | EMERGENCY SELF-LOCKING PET RETRACTOR - The present invention relates to a pet retractor, more particularly to an emergency self-locking pet retractor, comprising a collar, a leash, a leash spool, a shell body and a grip handle, in which it also comprises an emergency self-locking device. The emergency self-locking device includes a switch sliding block disposed on an external surface of the shell body and inserted into the shell body, a self-locking sliding block and a return spring thereof disposed in the shell body and attached to the switch sliding block, a self-locking baffle and a return torsion spring thereof disposed on an external surface of the leash spool and whose one end is hinged on the leash spool, and a self-locking baffle block disposed at the corresponding part on the external surface of the leash spool. When the pet suddenly breaks out or rises up, the emergency self-locking device can automatically lock the spool to prevent the leash from being pulled out, so that the pet cannot run around, attack people or damage properties. The pet is well protected from being hit by vehicles and it cannot hurt others. Consequently, the pet's safety is ensured, other people and properties will not be hurt or damaged and the owner's economic loss is avoided. | 05-23-2013 |

20150196598 | HUMAN CD8+ REGULATORY T CELLS INHIBIT GVHD AND PRESERVE GENERAL IMMUNITY IN HUMANIZED MICE - Graft-versus-host disease (GVHD) is a lethal complication of allograft transplantation. The current strategy of using immunosuppressive agents to control GVHD may cause general immune suppression and limit the effectiveness of allograft transplantation. Adoptive transfer of regulatory T cells (Treg) can prevent GVHD in rodents, indicating the therapeutic potential of Treg for GVHD in humans. However, the clinical application of Treg-based therapy is hampered by the low frequency of human Treg and the lack of a reliable model to test their therapeutic effects in vivo. Human alloantigen-specific Treg are generated from antigenically-naïve precursors in a large scale ex vivo using allogeneic activated B cells as stimulators. Here, a human allogeneic GVHD model is established in humanized mice to mimic GVHD after allograft transplantation in humans. The ex vivo-induced CD8 | 07-16-2015 |
20160045521 | BIOPHOSPHONATE COMPOUNDS AND GAMMA DELTA T CELL-MEDIATED THERAPY FOR TREATING EPSTEIN-BARR VIRUS-ASSOCIATED DISORDERS - Aminobisphosphonate pamidronate (PAM) can control Epstein-Barr virus (EBV) associated disorders in humanized mice through a Vγ9Vδ2-T-cell dependent mechanism. This suggests a strong potential for a therapeutic approach using PAM to boost human Vγ9Vδ2-T-cell immunity against EBV associated disorders, such as the lymphoproliferative disease (LPD), posttransplant lymphoproliferative disorder (PLPD), Hodgkin's disease, Burkitt's lymphoma, and nasopharyngeal carcinoma (NPC). | 02-18-2016 |

20090219076 | APPARATUS, SYSTEM, AND METHOD FOR GROUNDING INTEGRATED CIRCUIT OUTPUTS - An apparatus, system, and method are disclosed for grounding IC outputs. A first switching module turns on when an IC power supply voltage exceeds a base voltage. The first switching module is in communication with IC outputs and a common ground. The IC outputs are configured to be pulled up to the IC power supply voltage through pull-up resistors when a first voltage is driven lower than the base voltage. In addition, the first switching module connects the IC outputs to the common ground. A second switching module turns on, turns turn off the first switching module, disconnects the IC outputs from the common ground, and pulls the IC outputs up to the IC power supply voltage when the IC power supply voltage exceeds a minimum working voltage. | 09-03-2009 |
20090219766 | APPARATUS, SYSTEM, AND METHOD FOR ADJUSTING MEMORY HOLD TIME - An apparatus, system, and method are disclosed for adjusting memory hold time. A detection module detects a hold time violation for a memory. An adjustment module increases a first voltage of a voltage controller in response to the hold time violation. The voltage controller supplies electrical current at the first voltage to a memory controller and at a reference voltage to the memory. The first and reference voltages are set independently. | 09-03-2009 |

20160134272 | Switch Driver With a Low-Cost Cross-Conduction-Preventing Circuit - A driver for a power transistor switch comprising a FET complementary output stage which is driven by another FET complementary pre-driver stage which is further driven by an input-buffer and level-shifter stage. The pre-driver stage includes a current-limiting and cross-delaying circuit which is inserted in between drains terminals of a complementary FET pair. The current-limiting and cross-delaying circuit limits shoot-current at the pre-driver stage; and in conjunction with the FET pair and the input-buffer and level-shifter stage, it is adapted to delay turning on one complementary output FET until after the other complementary output FET is turned off, thereby preventing cross conduction at the output stage. | 05-12-2016 |
