Photovoltaic systems with managed output and methods for managing variability of output from photovoltaic systems are described. A system includes a photovoltaic module configured to receive and convert solar energy to DC power. The system also includes a sensor configured to detect a future change in solar energy to be received by the photovoltaic module. The system further includes a power conditioning unit coupled with the photovoltaic module and the sensor.
摘要:
A storage device within a ratchet arrangement for automatically storing a length of fastening material including a storage housing and a biasing member for drawing the fastening material into the storage housing. The fastening material can be used with a ratchet/handle tie-down mechanism, allowing for the dynamic portion of the webbing to automatically be retracted into the storage housing. The automatic retraction leaves little or no excess webbing or fastening material, such that a user does not have to tie off excess webbing or material.

A hitch pin for use in a hitch assembly is provided. The hitch pin includes a first end portion, a second end portion, and a transition portion. The size of the first end portion is different relative to the size of the second end portion. The two end portions are configured to fit different size apertures defined by a hitch assembly component. In further examples, the hitch pin can include a first end portion, a second end portion, a third end portion, and a transition portion. The first end portion is of a different size relative to both the second end portion and the third end portion.

A photovoltaic system includes solar cells and photovoltaic inverters configured to convert direct current generated by the solar cells to alternating current. Grid voltage at the point of interconnection (POI) of the photovoltaic system and the power grid is measured and compared to a setpoint. A control signal is generated based on the measured grid voltage. The control signal is provided to the photovoltaic inverters. The control signal is adjusted to cause the photovoltaic inverters to generate or absorb reactive power to respond to transient grid voltage changes.

Methods and systems for administrative management of a secure data storage network are disclosed. One system includes a secure storage appliance configured to host a plurality of volumes, each volume associated with a plurality of shares stored on a corresponding plurality of physical storage devices and having a plurality of volume management settings, wherein each volume is accessible by a group of one or more users, each user assigned an administrative access level, the volume management settings are editable by a first user from the group of one or more users associated with the volume and assigned an administrative access level sufficient to edit the volume management settings, and the volume management settings are inaccessible by a second user from outside the group of one or more users associated with the volume and assigned an administrative access level at least equal to that of the first user.

By coupling a rating engine with call processing, rating rules are generated that enable a flexible interface between call process and call rating without necessitating that fixed data be passed between them. The real time charging system (RCS) provides a process that creates a generic entity, called a bucket, and uses it to keep track of account information and/or to count types of usage. The bucket allows an operator to define accounts and usage counters and how they are used as part of the rating rules. Use of these buckets is defined in rating rules, thus turning control over subscriber account and usage counters to the network operator. Further, the RCS provides a calendar option for limiting times during which calls to general telephone numbers can be made or received.
摘要:
A ratcheting tie-down device includes a main body portion having first and second ends, and a rotatable reel located about the second end. A dynamic webbing is extendable from the first end of the main body portion and is windable about the reel. A static webbing is coupled to the main body portion about the second end. The device includes means for attaching at least one end of the dynamic webbing to an object, and means for ratcheting rotation of the reel to wind the dynamic webbing thereon. A lever arm is rotatable relative to the main body portion between a first position and a second position to cause ratcheting rotation of the ratchet wheel. In one example, the lever arm includes at least a pair of independent lever arm rails. In another example, the dynamic webbing travels underneath a guide member prior to being wound about the reel.

Investment casting shells are manufactured by incorporating fumed metal oxide dispersions, or doped fumed metal oxides as a binder into the casting shell. The investment casting shells containing the fumed metal oxides have improved characteristics, such as increased strength and a reduced surface roughness.
