ens Vectorization approach to isolating local maxima in an N-dimensional dataset By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Identification of maximum power scatters in an N-dimensional dataset generally requires two basic steps. The first step is to identify the max power scatters of the dataset and the second step removes neighboring power scatters (e.g., “hits”) of lower power. Current naïve approaches utilize an inefficient and computationally intensive brute force implementation which requires multiple comparisons of each initial “hit” power to all “hits” of lesser power. Such brute force implementations require 2×N×(M−1)! comparisons, where N is the number of dimensions and M is the number of “hits.” Embodiments of the present disclosure utilize vectorization to identify a plurality of neighboring hits for each max power scatter and removes the neighboring hits of lesser power that are within a predetermined isolation region. Advantageously, embodiments of the present invention perform M−1 comparisons. Full Article

ens Tensile strained semiconductor photon emission and detection devices and integrated photonics system By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT Tensile strained germanium is provided that can be sufficiently strained to provide a nearly direct band gap material or a direct band gap material. Compressively stressed or tensile stressed stressor materials in contact with germanium regions induce uniaxial or biaxial tensile strain in the germanium regions. Stressor materials may include silicon nitride or silicon germanium. The resulting strained germanium structure can be used to emit or detect photons including, for example, generating photons within a resonant cavity to provide a laser. Full Article
ens Three dimensional image projector stabilization circuit By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A method for providing a feedback circuit for a three dimensional projector. First and second input devices and a sensor for determining the rotational speed of the second input device are provided. A control device for controlling the rotational speed of the second input device and a phase locked loop (PLL) are provided. A phase reference signal is created based on the signal rate of the first input device. A phase signal is created based on the rotational speed of the second input device. The PLL compares the phase reference signal and the phase feedback signal to determine whether the first input device and the second input device are synchronized. A signal is sent to the control device for the second input device to change the rotational speed of the second input device in response to determining that the first input device and the second input device are not synchronized.

ens Sensing safety devices By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT Safety apparatuses for objects having at least one nut are disclosed. Contemplated apparatuses comprise a base, one or more nut caps, and one or more electronic sensors configured to acquire data related to a corresponding nut, wheel or tire. In some embodiments, a physical nut rotation indicator that can readily be observed by an operator is included, and a retention wall disposed on the base can operate in conjunction with the physical nut rotation indicator to block a rotation of a nut. Apparatuses are preferably configured to remain stable in harsher environments. Full Article
