Abstract: Disclosed is a hermetic AC electric motor that includes harmonics shunting such that high frequency harmonics are shunted from the AC electric motor without the use of one or more high frequency filters in the associated motor drive. A related method of operating an AC electric motor includes shunting high frequency harmonics to a fluid passing through the AC electric motor. Also disclosed is a simplified variable speed motor drive system which eliminates the need for a filter for removing high frequency harmonics.

Abstract: A method and apparatus for installing an application on a computer are disclosed. Following receipt of a request to install an application, a software state, comprising the new application and several of the applications installed on the computer, is derived. Then, the method determines whether the software state can be implemented on the computer. If the software state cannot be implemented on the computer, then the method derives another software state. This is repeated until the derived software state can be implemented on the computer system, or until determining that no software state exists which can be implemented on the computer system.

Abstract: A method for determining the operating status of a proposed application configuration on a first client including receiving updates from a plurality of clients, each update including a client identification, a previous state indication, a current state indication, and an indication of the operating status of the current state. The method also includes storing the updates in a database, the updates being stored such that the performance of a current state may be identified at two different times; receiving a proposed state change from the first client, the proposed state change including a current state of the first client and a proposed application to be added to the first client; querying the database to identify instances of the proposed state change; determining risks associated with adding the proposed application based on the results of querying the database; and transmitting to the first client a description of the risks associated with adding the proposed application.

Abstract: Embodiments of the invention provide the ability to determine whether a particular application may be safely added to a client computing device. Further, embodiments of the invention also allow for performing a rollback operation on clients experiencing a decrease of performance due to an addition of new software. For example, after a client updates to a new piece of software, a server may monitor the performance of the first client by analyzing a plurality of updates received from the first client. Each update may include a performance indicator. Using the updates, the server may detect a decrease in the performance of the first client. Upon detecting the decrease in the performance, the server may initiate a rollback to a previous state on the first client.

Abstract: A method of distributing applications between a plurality of machines forming a client system. The method includes determining that applications should be distributed to maximize hardware utilization of each or the plurality of machines; determining a plurality of possible configurations of applications among the plurality of machines; creating a list of all possible configurations; comparing the list of all possible configurations to a database of state information; removing configurations from the list if the configuration is the same as a state previously determined to be non-functional to create a pruned list; generating a score for each configuration on the pruned list by comparing each configuration with states information in the database; selecting the configurations with the highest score, the number of configurations equaling the number of machines; and deploying the selected configurations on the plurality of machines.
