Patent number: 8684802Abstract: A system that balances thermal variations within a set of computer systems in a datacenter. During operation, the system obtains a thermal flux map for the set of computer systems. The system then analyzes the thermal flux map to determine whether imbalances exist in the thermal flux across the set of computer systems. If so, the system can adjust: (1) the scheduling of loads across the set of computer systems, and/or (2) air conditioning within the datacenter, so that the thermal flux is more balanced across the set of computer systems.Type: GrantFiled: October 27, 2006Date of Patent: April 1, 2014Assignee: Oracle America, Inc.Inventors: Kenny C.

Patent number: 8500525Abstract: An elevator cab ceiling includes an upper ceiling panel and a lower ceiling panel that are vertically spaced apart from each other with an intermediate ceiling cavity between them. An inlet duct is associated with the upper ceiling panel and an outlet duct is associated with the lower ceiling panel. The inlet and outlet ducts are horizontally spaced apart from each other and are fluidly connected to each other through the intermediate ceiling cavity to form a ventilation path. This separation of inlet and outlet ducts by an intermediate ceiling cavity reduces airborne noise transmissions that enter an elevator cab through the ventilation path. In one example, at least one baffle is installed within the intermediate ceiling cavity between the inlet and outlet ducts to interrupt a flow between the inlet and outlet to further reduce any transmitted noise.Type: GrantFiled: February 3, 2005Date of Patent: August 6, 2013Assignee: Otis Elevator CompanyInventors: Daniel G.

Patent number: 8500527Abstract: An air outlet structure for an air conditioner, which can provide a sufficient volume and speed of air conditioning airflow, which has excellent directivity, and which has a thin air outlet directed to the interior of a vehicle. In the air outlet structure (10) for an air conditioner, a movable flow path member (14) provided in a case (12) can be deformed to a triangle and to a pentagon according to operation of a left-right adjustment knob (44), and this changes the shape of a flow path in the case (12). Accordingly, the flow path in the case (12) does not require fins for changing the direction of the left and right. As a result, the flow path in the case (12) can have a sufficient effective cross-sectional area to provide a sufficient volume and speed of air conditioning airflow.Type: GrantFiled: May 22, 2007Date of Patent: August 6, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Kimio Sakakibara
