Tesla motors’ open source revolution: Intellectual property and the carbon crisis

On the 12th June 2014, Elon Musk, the chief executive officer of the electric car manufacturer, Tesla Motors, announced in a blog that ‘all our patents belong to you.’ He explained that the company would adopt an open source philosophy in respect of its intellectual property in order to encourage the development of the industry of electric cars, and address the carbon crisis. Elon Musk made the dramatic, landmark announcement: Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology.

23andMe Inc.: Patent law and lifestyle genetics

The venture, 23andMe Inc., raises a host of issues in respect of patent law, policy, and practice in respect of lifestyle genetics and personalised medicine. The company observes: ‘We recognize that the availability of personal genetic information raises important issues at the nexus of ethics, law, and public policy’. 23andMe Inc. has tested the boundaries of patent law, with its patent applications, which cut across information technology, medicine, and biotechnology. The company’s research raises fundamental issues about patentability, especially in light of the litigation in Bilski v. Kappos, Mayo Collaborative Services v. Prometheus Laboratories Inc. and Association for Molecular Pathology v. United States Patent and Trademark Office and Myriad Genetics Inc. There has been much debate and controversy over 23andMe Inc. filing patent applications – particularly in respect of its granted patent on ‘Polymorphisms associated with Parkinson’s Disease’. The direct-to-consumer marketing of genetic testing by 23andMe Inc. has also raised important questions of bioethics and human rights. It is queried whether the terms of service for 23andMe Inc. provide adequate recognition of the concepts of informed consent and benefit-sharing, especially in light of litigation in this area in the United States. Given the patent thickets surrounding genetic testing, the case study of 23andMe Inc. also highlights questions about patent infringement and patent exceptions. The future reform of patent law, policy, and practice needs to take into account new developments in lifestyle genetics and personalised medicine – as exemplified by 23andMe Inc.

Breakfast at Tiffany's': eBay Inc., trade mark law, and counterfeiting

In an exploration of intellectual property and fashion, this article examines the question of the intermediary liability of online auction-houses for counterfeiting. In the United States, the illustrious jewellery store, Tiffany & Co, brought a legal action against eBay Inc, alleging direct trademark infringement, contributory trademark infringement, false advertising, unfair competition and trademark dilution. The luxury store depicted the online auction-house as a pirate bazaar, a flea-market and a haven for counterfeiting. During epic litigation, eBay Inc successfully defended itself against these allegations in a United States District Court and the United States Court of Appeals for the Second Circuit. Tiffany & Co made a desperate, unsuccessful effort to appeal the matter to the Supreme Court of the United States. The matter featured a number of interventions from amicus curiae — Tiffany was supported by Coty, the Fashion Designer's Guild, and the International Anticounterfeiting Coalition, while eBay was defended by publicly-spirited civil society groups such as Electronic Frontier Foundation, Public Citizen, and Public Knowledge as well as Yahoo!, Google Inc, Amazon.com, and associations representing telecommunications carriers and internet service providers. The litigation in the United States can be counterpointed with the fusillade of legal action against eBay in the European Union. In contrast to Tiffany & Co, Louis Vuitton triumphed over eBay in the French courts — claiming its victory as vindication of the need to protect the commercial interests and cultural heritage of France. However, eBay has fared somewhat better in a dispute with L’Oréal in Great Britain and the European Court of Justice. It is argued that, in a time of flux and uncertainty, Australia should follow the position of the United States courts in Tiffany & Co v eBay Inc. The final part examines the ramifications of this litigation over online auction-houses for trade mark law reform and consumer rights; parallel disputes over intermediary liability and safe harbours in the field of copyright law and the Anti-Counterfeiting Trade Agreement 2010. The conclusion calls for a revision of trade mark law, animated by a respect for consumers’ rights and interests in the electronic marketplace.

Australian Property Institute Inc, Submission to the Productivity Commission on Intellectual Property Arrangements – Issues Paper

This submission responds to the document Intellectual Property Arrangements Issues Paper (Issues Paper) released by the Productivity Commission in October 2015 for public consultation and input by 30 November 2015. The API is grateful for the extension of time granted by the Commission to complete and lodge this submission. The overall need for an inquiry into intellectual property is supported by API. In particular it is noted with approval that the Commission states in its Issues Paper that it is to consider the appropriate balance between “incentives for innovation and investments, and the interests of both individuals and businesses in assessing products”.1 However, API is of the view that intellectual property in the area of real property presents a number of issues which are not fully canvassed in the abovementioned Issues Paper. Intellectual property embedded in valuation and other property-related reports of API members involves the acquisition of information which may possibly be confidential. Yet, when engaged in banks and financial institutions the intellectual property in such valuations and/ or reports is commonly required to be passed to the client bank or financial institution. In the Issues Paper it is proposed that there are seven different forms of intellectual property rights.2 It is the view of API that an eight form exists, namely private agreements. The Issues Paper, however, regards private agreements between firms as alternatives to intellectual property rights. The API considers that “secrecy or confidentiality arrangements”3 as identified in the Issues Paper form a much larger part of the manner in which intellectual property is maintained in Australia for the purposes of trade secrecy or more often, financial confidentiality...

Boundary-layer effects on internal flow choking in dual-thrust solid rocket motors

Theoretical studies have been carried out to examine internal flow choking in the inert simulators of a dual-thrust motor. Using a two-dimensional k-omega turbulence model, detailed parametric studies have been carried out to examine aerodynamic choking and the existence of a fluid throat at the transition region during the startup transient of dual-thrust motors. This code solves standard k-omega turbulence equations with shear flow corrections using a coupled second-order-implicit unsteady formulation. In the numerical study, a fully implicit finite volume scheme of the compressible, Reynolds-averaged, Navier-Stokes equations is employed. It was observed that, at the subsonic inflow conditions, there is a possibility of the occurrence of internal flow choking in dual-thrust motors due to the formation of a fluid throat at the beginning of the transition region induced by area blockage caused by boundary-layer-displacement thickness. It has been observed that a 55% increase in the upstream port area of the dual-thrust motor contributes to a 25% reduction in blockage factor at the transition region, which could negate the internal How choking and supplement with an early choking of the dual-thrust motor nozzle. If the height of the upstream port relative to the motor length is too small, the developing boundary layers from either side of the port can interact, leading to a choked,flow. On the other hand, if the developing boundary layers are far enough apart, then choking does not occur. The blockage factor is greater in magnitude for the choked case than for the unchoked case. More tangible explanations are presented in this paper for the boundary-layer blockage and the internal flow choking in dual-thrust motors, which hitherto has been unexplored.

Design of first- and second-order sliding mode observers for induction motors using a stator-flux model

We extend current research in the area of 'sensorless' control of induction motors by presenting two observers based on first- and second-order sliding mode control theories for the simultaneous estimation of flux and speed. We base the observers on the stator-flux model of the motor instead of the usual rotor-flux model mainly because of the uncertain rotor resistance that plays a significant role in the latter. By designing the observers as if they are sliding mode controllers, we lend the properties of parameter insensitive closed-loop dynamics and finite time convergence to the stator flux and speed estimation schemes. We also present simulation and experimental results to validate the operation of the observers.

High Starting Torque Drive For Step Motors

A bi-level voltage drive circuit for step motors that can provide the required high starting torque is described. In this circuit, microprocessor 8085 and parallel port interface 8255 are used for generating the code sequence. The inverter buffer 74LS06 provides enough drive to a darlington pair transistor. The comparator LM339 is used to compare the required voltage for step motor with the set value. This circuit can be effectively used for step motors having maximum rated current of less than 15 A with proper heat sink.

Modeling re-ignition and chuffing in solid rocket motors

A nonlinear model is developed to numerically simulate dynamic combustion inside a solid rocket motor chamber. Using this model, the phenomena of re-ignition and chuffing are investigated under low-L* conditions. The model consists of two separate submodels (coupled to each other), one for unsteady burning of propellant and the other for unsteady conservation of mass and energy within the chamber. The latter yields instantaneous pressure and temperature within the chamber. The instantaneous burning rate is calculated using a one-dimensional, nonlinear, transient gas-phase model previously developed by the authors. The results presented in this paper show that the model predicts not only the critical L*, but also the various regimes of L*-instabihty. Specifically, the results exhibit (1) amplifying pressure oscillations leading to extinction, and (2) re-ignition after a dormant period following extinction. The re-ignition could be observed only when a radiation heat flux (from the combustion chamber to the propellant surface) was included. Certain high-frequency oscillations, possibly due to intrinsic instability, are observed when the pressure overshoots during re-ignition. At very low values of initial L*, successive cycles of extinction/reignition displaying typical characteristics of chuffing are predicted. Variations of the chuffing frequency and the thickness of propellant burned off during a chuff with L* are found to be qualitatively the same as that reported from experimental observations.

A Hybrid Energy-insensitive Explicit Guidance Scheme for Long Range Flight Vehicles with Solid Motors

Combining the newly developed nonlinear model predictive static programming technique with null range direction concept, a novel explicit energy-insensitive guidance design method is presented in this paper for long range flight vehicles, which leads to a closed form solution of the necessary guidance command update. Owing to the closed form nature, it does not lead to computational difficulties and the proposed optimal guidance algorithm can be implemented online. The guidance law is verified in a solid motor propelled long range flight vehicle, for which coming up with an effective guidance law is more difficult as compared to a liquid engine propelled vehicle (mainly because of the absence of thrust cutoff facility). Assuming the starting point of the second stage to be a deterministic point beyond the atmosphere, the scheme guides the vehicle properly so that it completes the mission within a tight error bound. The simulation results demonstrate its ability to intercept the target, even with an uncertainty of greater than 10% in burnout time.

Switching Transients in Single-Phase Induction Motors

The subject of transients in polyphase induction motors and synchronous machines has been studied in very great detail by several investigators, but no published literature exists dealing exclusively with the analysis of the problem of transients in single-phase induction motors. This particular problem has been studied in this paper by applying the Laplace transform. The results of actual computation of the currents and developed electrical torque are compared with the data obtained by setting up the integro-differential equations of the machine on an electronic differential analyzer. It is shown that if the motor is switched on to the supply when the potential passes through its zero value, there is a pulsating fundamental frequency torque superimposed on the average steady-state unidirectional torque. If, on the other hand, the switch is closed when the applied potential passes through its maximum value, the developed electrical torque settles down to its final steady-state value during the first cycle of the supply voltage.
