Abstract: A controller on a harvester vehicle is arranged to automatically identify a header in electrical communication with the vehicle upon key activation of the harvester vehicle. Programming instructions on the controller can generate notifications to the user based upon a state of activation of the float mechanism and the state of header identity detection. The controller also prompts the user to confirm the identity of the header if the detected identity of the header has changed. The controller also uses header identity to log usage hours of the header on the computer controller in association with the identity of the header such that maintenance schedules for a plurality of different headers interchangeably used on a common harvester vehicle can be tracked.

Abstract: In a harvesting machine having an agricultural header which is adjustable in height, a computer controller includes programming instructions to allow an operator to associate a plurality of different harvester functions with a single programmable input button providing single-touch actuation. The input button is programmable to return the header height to a preset height value in addition to controlling position of one or more additional accessories such as a double windrow attachment, a deck shifting set of drapers of the header, and/or a crop compressor attachment, etc. Programming of the input button uses navigational inputs to select which functions of the machine are associated with the button, followed by a press-and-hold actuation to set the preset value of all associated functions based on the current operating condition.

Abstract: A single unit with a backhaul interface and radio card able to support both metro cell outdoor (MCO) and metro radio outdoor (MRO) operations. The single unit includes a switch used to switch between these operational modes. The single unit is versatile from the standpoint that MCO or MRO operations may be selected at the time of installation, and this selection may be changed at any time while operating. The single unit configuration provides a low power MRO mode requiring up to 80% less power than the MCO mode, as the switching function of the single unit can power down all unused internal components and allow radio signals received at a backhaul interface to be exchanged directly with a radio card.

Abstract: A method of validating software including maintaining, in a trusted computing system, a copy of at least portions of data of the software, the software comprising data in an untrusted computing system. The method includes, with the trusted computing system, specifying selected data from data included in the copy as hash data, generating an executable file for generating a hash based on the specified hash data, executing the executable file to generate a check hash using the specified selected data from the copy as the hash data, and determining whether the software is valid based, at least in part, on a comparison of the check hash to an access hash generated by execution of the executable file by the untrusted computing system using the specified selected data from the untrusted computing system as the hash data.

Abstract: There is provided a memory access control method and system in which one or more memory blocks are allocated to hold data for a dataset and the one or more memory blocks are associated with metadata related to the dataset and a policy related to allowing access to the one or more memory blocks for attachment of the memory blocks to a node. Upon receiving a request from a requesting entity to access an allocated memory block for attachment of the requested memory block to a node, the policy is enforced to determine whether to allow access to the requested memory block for the attachment of the requested memory block to the node given a set of memory blocks already attached to the node.

Abstract: A method of lifting a structure includes extending a pipe so as to have one end opening to a lens in the earth, connecting a pump to the pipe, and pumping a grout material through the pipe and into the lens so as to cause a strata of the earth above the lens to heave upwardly and to cause the structure to move upwardly. The grout is solidified in the lens. The pipe is removed after the step of pumping. The grout is a low mobility cement grout. A location of the lens nearest to the structure is determined prior to the step of extending the pipe.

Abstract: An apparatus includes a motor driver configured to drive a motor across a pair of input terminals to the motor and a current sense unit configured to sense the motor's electrical current amplitude. Further, an angular frequency extractor is operatively coupled to the motor driver and the current sense unit and configured to detect discontinuities in the motor's electrical current amplitude. The angular frequency extractor also is configured to determine a time period for one complete revolution of a rotor of the motor and to generate a feedback signal based on the determined period to control an angular frequency of the motor. The feedback signal may be used to adjust how the motor is being driven (e.g., to slow the motor down or speed it up).

Abstract: A system has a virtual overlay infrastructure mapped onto physical resources for processing, storage and network communications, the virtual infrastructure having virtual entities for processing, storage and network communications. Virtual infrastructures of different users share physical resources but are isolated. Each infrastructure has its own infrastructure controller to create and configure the infrastructure. It has a user accessible part (CFC) for configuration of that user's infrastructure, and a user inaccessible part (UFC) able to access the mapping and the physical resources. This increases user control to ease system administration, while maintaining security by limiting access to the mapping.
