Inventors and Patents From the City of Oakland
Inventors in the city of Oakland have been awarded patents for a variety of inventions. These include the Co-inventors of a three-dimensional folded vapor condenser, Ettore Steccone’s squeegee, and Eneura’s magnetic pulsing system for inducing electric currents in the human body.
Co-inventors of a vapor condenser with three-dimensional folded structure
A three-dimensional folded structure is an effective way to reduce heat transfer in a vapor condenser. This structure can operate at high noncondensable fractions. This type of condenser can be predicted using simple models. However, these models require a wall temperature specification to predict the local condensation rate. The present model addresses this issue by including the effects of secondary side heat transfer and interfacial shear stress. Using this model, the condensing rate is derived using a Nusselt-type algebraic equation.
The structure of the evaporator is based on an aluminum tube and copper tubing. The copper tubes are joined with the aluminum plates using a procedure called fusion. To fuse the two copper tubings together, a bullet is fed through the copper tubing and expands against the inner surface of the plate hole. The bullet bond helps transfer heat from one part of the structure to another.
Ettore Steccone’s squeegee
The modern squeegee was invented by Ettore Steccone in 1936. It has a lightweight, T-shaped handle and a single, flexible blade. Steccone’s original squeegee was more ergonomic and more efficient than the Chicago Squeegee. Today, the Ettore squeegee is made by a family-owned factory in Oakland, California.
Ettore has a long and storied history in the industry. The company first made its squeegees in a garage and eventually moved into a factory. Throughout the years, Ettore Steccone continued to develop and sell his squeegees, despite challenges including losses in patents and name rights, world wars, and metal shortages.
Although Ettore Steccone died at the age of 87, his son Michael Steccone is still the CEO. It is estimated that the family makes about 75 percent of squeegees used by professional window cleaners. Ettore also makes 60 percent of its products for consumers.
After the World War I, Ettore Steccone moved to the U.S. to seek his fortune. He took his window washing profession to America and began earning his living doing so. The squeegees used at the time were bulky and heavy, and required twelve screws to change the blades. Luckily, Steccone saw the market for a new squeegee and created a tool to suit his needs.
Ettore Steccone’s original squeegee is still the favorite of professional window cleaners the world over. Its original design is a patented rubber blade that cleans glass surfaces streak-free and is rustproof. This squeegee also comes with a REA-C-H extension pole, which allows window cleaners to reach higher windows.
Eneura’s magnetic pulsing system for inducing electric currents in a human body
Magnetic pulses applied to one part of the body, such as the carotid sinus, can cause an electric current pulse at another part of the body. This could have therapeutic properties. It has been demonstrated that magnetic pulses applied to the vagal nerve can help stop atrial fibrillation.
The magnetic field strength can range between 0.2 to 1.0 Tesla. This is a safe and effective way to induce electric currents in a human body. The magnetic pulsing device can be adapted to fit a patient’s anatomy.
Magnetic pulsing is a noninvasive technique for treating a variety of neurological disorders. Neuralieve Inc., which is now trading under the name eNeura Therapeutics, has developed a magnetic pulsing device known as the MagStim. The system consists of two independent high-voltage power supplies and energy-storage capacitor banks. It is controlled by a microprocessor.
Magnetic pulses can be used for neurological treatments, such as migraine headaches. A high intensity magnetic pulse applied to the brain or other parts of the body can stop the pain and reduce its severity. The device can be portable and operated by the patient. The system can be powered by a household receptacle, automobile receptacle, or a battery.
The system is able to warn the patient if the magnetic pulse exceeds its tolerance. A warning voice and a visual display are available for the patient. Moreover, the device can be connected to a service center, where a technician can check its specifications and time history.
Inventors in large cities are more likely to invent in unusual places
The results of a recent study conducted by Harvard researchers suggest that children raised in big cities are more likely to become inventors. For example, children raised in the tech sector are more likely to patent computer technology, while those raised in the heartland of Minnesota are more likely to develop medical devices. The findings of the study also support the notion that education plays a role in enabling individuals to develop innovative ideas.
The study also showed that inventors from large cities are more likely to move to places where there are more opportunities to innovate. In Fremont, for instance, many of the country’s largest companies are located here, including Tesla. Boston Scientific and Lam Research are also located here. As a result, many patents are tied to this city.
