Foam Metallic Glass: U.S. Patent No. 5,384,203
The patent teaches a method of producing bulk metallic foam products that is also applicable to manufacturing organic and metal alloy foams. The technique detailed in the Foam Metallic Glass patent produces foams with an open-cell structure, and the produced foam is likely a Metal Sponge material. Metallic foams are increasing in demand, and exhibit the greatest growth rate in this business sector.
Since the Foam Metallic Glass patent teaches a fundamental technique for metallic foam production, this patent would be useful to companies in the market or anticipating entering the growing metal foam market, or needing to augment their metallic foam patent portfolio with a complimentary technology. Recently, Apple Inc. purchased a worldwide license to the Liquidmetal portfolio. There has been much speculation regarding the objective of the Apple/Liquidmetal licensing agreement, but the ability to cast a lightweight metal case in its final form for portable electronics cannot be overlooked for its durability and aesthetic value. Metallic foam materials and alloys are at the leading edge of metal fabrication and materials engineering, and there are many applications for this technology in consumer products.
Uninterruptible Power Supplies: U.S. Patent No. 7,307,360
Uninterruptible power supplies (UPSs) are generally discussed herein with particular discussions extended to fuel-cell-based UPSs used in conjunction with DC power supplies for improved operating efficiencies. With a wide voltage DC power supply, a DC-AC inverter may be omitted from the UPS and power from a back-up power source, such as a battery or a fuel cell, may be applied directly to the DC power supply without performing two power conversions. The end result is a more efficient system capable of longer operating time.
Digital Printing Densitometer: U.S. Patent Nos. 6,567,171: “Digital densitometer with controlled light emitter,” 6,671,052- “Multi-channel densitometer” and 6,791,485: “Digital densitometer using light-to-frequency converter”
This offering is for the assignment of three U.S. Patents related to digital technology applied to densitometers which measures the darkness and color of printed material for use in electro photography.
- The three patents relate to densitometer and more particularly to digital technology applied to densitometers. Each of the patented technology provides a solution to drawbacks present in conventional analog densitometers. The advantages of devices developed based on the patented technologies are reduced costs, compact space requirements and enhanced technology.
- Further, digital color presses typically use Electro Photography (EP) technology and require “in-line” densitometers to maintain consistent high quality printed output. Digital presses efficiently print short runs and variable data, and thus have become more important relative to older printing technology such as offset printing.
- Further, the digital approach for densitometers provides better noise immunity in the electronically noisy environment inside digital presses. Additionally, the patented technology cuts harmful exposure from the densitometer to prevent image artifacts.
- The Electro Photography market is pervasively using densitometers for various applications. Our market research analysis shows that there is a huge market for these patented technologies.
- The analysis also shows that the patented technology has been implemented in the market.
Apparatus, and associated method, for controlling the repetition rate of an intermittent windshield wiper (Hewlett-Packard): U.S. Patent No. 7,423,399
A user interface, formed of a pair of momentary contact switches, is used to set the repetition rate of intermittent operation of a wiper blade and, subsequently, when desired, to terminate the intermittent operation. A first of the switches is actuated two times, with the time period separating the actuations defining the repetition rate of the wiper blade when in the intermittent mode of operation.
Product Marker System: U.S. Patent Nos. 6,951,687 and 7,163,744 - "Multi-functional product markers and methods for making and using the same"
The two patents describe structure of a polymeric fiber that can be used in a product marker. Such a fiber can store information either by combination of voids and grooves or by areas of optically detectable difference.
-
Both of the patented technologies provide a solution to drawbacks present in conventional marking system. Markers developed on the patented technologies will have high information storage capacity, environmental and biological compatibility, sub-millimeter scale binary data encoding capacity, and manipulability. This would make a marker safer, more reliable, easily read, and inexpensive.
-
Such markers have range of applications across industries. However, increased focus on human health makes the pharmaceutical and food industries the target application areas. Many nations have enforced regulations governing the mandate of traceability in food products. This would fuel the demand of high-tech but safe and inexpensive markers.
-
Based on a combination of the market and technical analysis, it can be said that the successful bidder of the patent portfolio will have an opportunity to gain an advantage in the Product Marking market.
