Making the World’s Smallest Video Camera

Tuesday, Apr 1, 2014 - 7:00 pm

This talk will describe a new class of computational optical sensors and imagers that do not rely on traditional refractive or reflective focusing, but instead on special diffractive optical elements integrated with CMOS photodiode arrays. The diffractive elements have provably optimal optical properties essential for imaging, and act as a visual chirp as well as preserve full Fourier image information on the photodiode arrays.

Images are not captured as in traditional imaging systems, but rather computed from raw photodiode signals. Because such imagers forgo the use of lenses, they can be made unprecedentedly small – as small as the cross-section of a human hair. Such imagers have extended depth of field – from roughly 1mm to infinity – and should find use in numerous applications, from endoscopy to infra-red and surveillance imaging and more. Furthermore, the gratings and signal processing can be tailored to specific applications from visual motion estimation to barcode reading and others.

Valuing Intellectual Capital

Speaker: Dr. Gio Wiederhold

Intellectual capital comprises the non-tangible components that contribute to corporate income, including the competence of its human workforce and the intellectual property that they create and exploit.

The principle of valuing anything is simple: it is the net-present-value of its the future benefits. However, the practice of valuing is harder. Gio will cover methods used to assess the value of exports of IP rights to offshore sites – a primary means used by high-technology businesses to minimize their taxes.

Multiple types of taxhaven entities are employed to create the common Dutch Sandwich structure. Misvaluation is rife, and very profitable for owners of the IP. Gio will present ten common means of misvaluation that in combination reduce prices paid for rights to collect income to less than 10% of their actual value – a fact that often results in both the IP creators the countries where the work is done losing out since they are not informed of this misvaluation.

The amount of financial capital held in tax havens is now about $2 trillion – equal to 40% of the US national debt owed to foreign creditors, and this affects corporate investment and job creation. Addressing the issue constructively is more complex than closing loopholes. An unexpected result from Gio’s work is that abolishing corporate taxation entirely and not having reduced rates on dividend and capital gains income is the only technically feasible solution, although this notion is often distasteful to individuals.

Dr. Gio Wiederhold is an emeritus professor at Stanford University and a fellow of the IEEE, the ACM and the ACMI. He consulted for a wide variety of companies and agencies during his career and later academic life. Shortly after his retirement from Stanford, Gio started consulting exclusively for the IRS on the valuation of exports of intellectual property rights – work that led to the 2013 Springer Verlag book Valuing Intellectual Capital: Multinationals and Taxhavens.
