There are few companies currently operating which have more impact on global development in energy and industrial technologies than General Electric of Fairfield, CT. The recent third quarter financial report published by the corporation indicated a better-than-expected 11 percent growth in profits, mainly owing to large increases in orders for industrial equipment like jet engines and rail locomotives from all over the world. GE may be looking to raise capital as a recent filing with the U.S. Securities and Exchange Commission indicates that the company is looking to sell 75 million shares directly to the public for about $2 billion. General Electric is also making a foray into the growing world of 3D printing manufacture with its recent announcement that it would build a 125,000 square foot 3D printing facility for $32 million in Findlay, PA.

General Electric is a regular feature of the Companies We Follow series. What we saw today in the patent applications filed by this company with the U.S. Patent and Trademark Office showed us that research and development at the company is very focused on industrial and medical sectors. Many of the technologies we discuss in more detail below pertain to railway and other vehicular technologies. A few patent applications discuss improvements to electrical utility systems, including one technique for monitoring plant activity near electrical grid components to identify exactly when to clear vegetation away from power lines.

The strong patent portfolio enjoyed by General Electric enjoyed a number of important additions in recent weeks. Some of the most intriguing that we saw today involve medical innovations, including systems for the synchronization of imaging data collected during a procedure to better guide a medical professional during a procedures. We’re also sharing a patent protecting a useful technology for locating defects in an underground cable to ensure consistent delivery of electrical utilities.

Analysis of electrical systems to improve the delivery of utility services are also disclosed by U.S. Patent Application No. 20140310138, filed under the title Methods and Systems for Estimating Recoverable Utility Revenue. The utility analytics system of this invention is configured to derive the probability of non-technical and technical utility losses as well as the probability of recovering revenue in case of a utility loss. The invention is intended to ensure that energy deliveries across electrical grids do not go unbilled by energy providers.

We were also intrigued by a couple of patent applications featuring technologies with implications for the healthcare and medical sectors. Methods of limiting the risk of infection among patients are the focus of U.S. Patent Application No. 20140303996, which is titled System and Method to Manage Delivery Healthcare to a Patient. This patent application would protect a method of managing delivery of healthcare to a patient through a plurality of resources that involves tracking the ingress or egress of resources relative to a sterile zone. The activity monitoring techniques designed to reduce infection risks in hospitals is also useful in other medical settings, including ambulatory, home or inpatient settings. We also noted a novel technique for the detection of prostate cancer discussed within U.S. Patent Application No. 20140314299, titled System and Method for Multiplexed Biomarker Quantitation Using Single Cell Segmentation on Sequentially Stained Tissue. The computer-implemented method that would be protected through this patent application enables analysis of tissue types, cell units and sub-cellular units to determine the expression levels for specific biomarkers. The invention is intended to segment, group and quantify molecular protein profiles at the sub-cellular level, which can enable the correlation of spatial and molecular cell configurations with molecular information of different cancer types.

    “This method of modifying energy usage plans is intended for use with railway cars but could be implemented on a variety of electric vehicles, including off-road vehicles, automobiles and marine vessels” (your comment on the ‘460 application)
    Actually, no, it couldn’t, the system depends on a common power source or grid for all vehicles, something which is only true for railway vehicles and trams. Automobiles and marine vessels have independent power sources.
