A control system and method to determine position of a rotor relative to a stator for a synchronous multipole electrical machine is presented, including one for application on a fuel/electric hybrid powertrain for a vehicle. The machine includes a stator, a rotor, and a rotor position sensing mechanism. The control system controls the electrical machine, in conjunction with an electrical storage device and an inverter, using algorithms and calibrations which derive a rotor position based upon a sensorless position sensing technique, and determine an offset from a sensed rotor position. Electrical output from the inverter to the machine is controlled based the offset, which is stored non-volatile memory. A rotor position is derived based upon a sensorless position sensing technique during initial machine operation after startup of the machine, and includes operation in a torque-generative mode and in an electrical energy-generative mode.

A deepwater windpower plant (DWP) has a tension leg-type floating platform with an evacuable base for adjusting its buoyancy for installation at ocean depths ranging from 40 meters up to 1.5 kilometers and more. The DWP has a typical offshore wind turbine assembled close to shore which is then towed to a desired installation site on the ocean, and held in place by a gravity anchoring base (GAB), to which an evacuable portion or space of the DWP platform is anchored. The GAB has upwardly extending mooring tethers and a power cable which are brought to the ocean surface by attached buoys. The GAB is sunk to the ocean floor at the installation site under controlled conditions so that the GAB lands flat on the ocean floor. As the GAB sinks to the ocean floor, the mooring tethers and power cable are pulled to the surface by their respective buoys. The GAB is loaded with heavy ballast material that can be dropped from barges on the ocean surface into the upwardly open GAB below the barges.

Systems and methods are described for updating an influence model used to manage physical conditions of an environmentally controlled space. A method comprises operating an environmental maintenance system in a first production mode with the influence model until an event causes the system to enter a second production mode. In the second production mode a first actuator's operation level is varied and operation levels of other actuators are optimized. The influence model is adjusted based on the operation levels.

Articles having microreplicated film surfaces are also disclosed that have an advantage of providing microchannels for fluid egress for an effective period of time. Multiple microembossed patterns produce microreplicated film surfaces having both microchannels for fluid egress and pegs for improved film properties.

A first connector is disposed on a first end of a lead in a lead set for use with a plasma arc torch. The first connector is capable of engaging a second connector by causing a compression force in a second connector. The second connector compression force is caused by application of a translational force along a longitudinal axis. The second connector causes, upon application of a depression force along the longitudinal axis, disengagement of the first connector. The second causes disengagement of the first connector upon application of a linear force applied along the longitudinal axis to at least one of the first connector and the second connector. The second end of the lead may also be connected to a power supply. Methods for connecting and disconnecting a lead are also disclosed.

The invention relates to a cooling fan for use in a motor vehicle. To achieve improved cooling of an electric motor it is proposed that the motor housing enclosing the electric motor be used as a heat sink for emitting waste heat into a cooling air flow. The cooling air flow for cooling the electric motor is routed here through the interior of the motor housing and subsequently along the outside of the motor housing over cooling elements in the areas of the air inlet openings and in the area or an air exit gap between fan wheel hub and front part of the motor housing. The cooling air flow is created in this case by the fan wheel hub of the fan wheel driven by the electric motor.

The invention belongs to the technical filed of security inspection and relates to a vertical mechanical microwave scanning active imaging personnel security inspection system. By means of creative design and through adoption of a pair of horizontal detection arrays which are separately arranged in parallel on two sides or the front side and the back side of an inspected person in a vertical mode, vertical scanning imaging for the inspected person is conducted. Each detection array is in a shape of a straight array or a bow shape with two inwards folded heads or an arc shape or the like. Compared with an existing adopted vertical detection array active imaging personnel security inspection system, the vertical mechanical microwave scanning active imaging personnel security inspection system has the advantages that the number of transmit-receive components of the detection arrays can be reduced greatly and a system structure is simplified. Not only is convenience brought to storage, transportation, installation and usage but also system cost can be reduced.

An automated storage/retrieval system has two pairs of multi-tier racks that are arranged in series. An elevator is disposed between the two pairs of multi-tier racks. The elevator enables a load to be delivered to and received from the two pairs of multi-tier racks. The automated storage/retrieval system having such a tandem structure not only can provide the same storage capacity as that of a conventional configuration in which two pairs of multi-tier racks are arranged in parallel, but also can be applied to a building with a limited height since the system does not need to have an extended height. Since only one elevator is needed, the number of units is less than that of a conventional system, reducing manufacturing cost and an installation space for the system.
