Abstract: An A-frame-shaped truss foundation system for a single-axis tracker with a bearing assembly sitting atop a pair of adjacent angled truss legs joined together with an adapter so that the axis of rotation of the tracker is aligned with a work point of the A-frame. Several such foundation systems are arranged along a North-South row to support a tracker torque tube.

Abstract: A single-axis tracker supported by multiple A-frame-shaped single-truss foundations that translate lateral loads into axial forces of tension and compression, and at least one truss foundation supporting the torque tube drive motor or other tracker component subject to axial loads to provide support for lateral loads as well as loads oriented along the axis of the torque tube.

Abstract: A machine for rotary driving screw anchors into underlying ground and related. The machine has a mast with a rotary driver and a mandrel driver oriented on a common axis. The mandrel driver passes a mandrel through the rotary driver and the screw anchor to allow the mandrel to be actuated ahead of the screw anchor while the rotary driver drives the screw anchor into the ground. Alternatively, the mandrel driver may also drive a hammering drill through the screw anchor to clear a path ahead of it through subsurface rocks.

Abstract: A system for simultaneously driving multiple piles into the ground to create A-frame type structures that are anchored by piles running at angles to one another and to the ground. The system comprises a guide assembly and an actuator for driving the piles into supporting ground at the same time. The actuator may engage slots or teeth in the pile to drive them into the ground and/or may apply torque and downward pressure.

Abstract: A system for simultaneously driving multiple piles into the ground to create A-frame type structures that are anchored by piles running at angles to one other and to the ground. The system comprises a guide assembly and an actuator for moving piles through the guide assembly and the actuator (such as a meshing gear, ratchet or rollers) that engages a slots or teeth in the side portion of the pile to drive the piles into the ground.

Abstract: An automobile door hanger apparatus. The automobile door hanger apparatus includes a vertical member with two arms. The two arms have two plates on them that provide tubular members. The tubular members are in vertical alignment and are sized so that a removable automobile door can be attached to them. The automobile door hanger apparatus allows for four removable automobile doors to be attached to it such that the doors are safely and effectively stored.

Abstract: A system and method for deployment of a software image to a plurality of target devices are disclosed. A method may include communicatively coupling a root node device to a plurality of internal node devices, and communicatively coupling a plurality of leaf node devices to the root node devices and the internal node devices. The root node device may transmit a software image from the root node device to at least two of the internal node devices, and each internal node device may transmit the software image to at least one other internal node device or leaf node device.

Abstract: In a method of configuring a plurality of computer systems coupled through a network, each computer system comprises a bootable hard disk partition and the method comprises the steps of: automatically assigning an IP node address to each computer system coupled with the network; establishing a master node and creating a re-deployment image partition; synchronizing all computer systems which should receive the re-deployment image partition; broadcasting the re-deployment image partition from the master node; receiving the re-deployment image partition at each computer system; re-booting each computer system from their respective hard disk partition.

Abstract: A system and method for configuring systems uses layered profiles. A separate profile is selected for multiple characteristics of a particular system. Each selected profile may then be used to generate a configuration layer associated with each selected profile. The system may then use multiple configuration layers to configure a system, resulting in a system configured according to the selected profiles.

Abstract: A method and system are provided for assigning network addresses to multiple nodes in a computer cluster. Each of the nodes in the cluster may be provided with access to a network that interconnects the various nodes of the cluster. Upon initialization of the cluster, each node, in turn, may issue a ping of one or more network addresses. If the ping does not elicit a response from any other node within the cluster, then the network address may be deemed available and the node that issued the ping may assign that network address to itself. If the ping did elicit a response from another node, then the node that issued the ping tries other network addresses until an available network address is found.

Abstract: A seismic energy dissipation system for use with structures such as buildings, bridges and the like. The system includes a gravity frame, at least one reaction frame, and connection apparatus for connecting the gravity frame and the reaction frame. The connection apparatus includes springs for setting a period of response and energy dissipation units for dissipating energy within the structure, thus controlling the response of a structure with respect to internal forces, accelerations and deformations due to external excitations such as wind or earthquake.
