app 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
app Apparatus and method for assisting vertical takeoff vehicles By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT According to one aspect of the present invention, a radar system is provided which accurately measures the surface profile in a wide sector beneath and forward of a helicopter, to aid low level transit and landing in poor visibility. This uses an electronic beam synthesis technique to form multiple beams directed at the area of interest, each measuring the distance to the first reflected signal received by each beam. These distances represent the profile of the ground and any objects on the ground. A processor then compares the measured profile with the ideal ground profile for safe landing. If the deviations from straight and level exceed the specified requirement for safe landing, or if sufficient rotor clearance is not detected, then a warning is given to the operator. A display will show the measured ground profile highlighting the unsafe regions, allowing the operator to seek a safe region to land. The novelty lies in the way the beams are formed to measure and display the ground profile and provide a warning system. This beam-forming technique is simpler and more cost effective than with a conventional phased array radar. Full Article

In threshold learning, first, the brushless motor is stopped at an initial position. The brushless motor is then rotated by performing phase energization based on the energization mode from the stopped state. The voltage of the non-energized phase at an angular position of switching the energization mode is detected from a maximum value or a minimum value of the voltage of the non-energized phase during the rotation, and the threshold is learned based on the detected voltage. Alternatively, the brushless motor is positioned at the angular position of switching the energization mode by maintaining one energization mode, and then the energization mode is switched to the next energization mode. The voltage of the non-energized phase immediately after the switching to the energization mode is detected, and the detected voltage of the non-energized phase is learned as the threshold used to determine the timing of switching to the next energization mode.

app System and apparatus for improved wheelchair lift By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A wheelchair lift mounted on the rear of an automobile for transporting a wheelchair, scooter or other mobility device includes two or more sets of sensors. A first set of sensors is located at the distal ends of the wheelchair lift platform for use when the platform is horizontal. A 2nd set of sensors is located on the base of the wheelchair lift for use when the platform is folded vertically. The sensors alert a driver to the presence of objects in close proximity to the rear of the vehicle when driven in reverse. They switch automatically activates the base sensors when the platform is folded and the platform sensors when the platform is horizontal. Full Article
app Method for determining substrate transportation path, substrate transporting apparatus, substrate processing apparatus and computer-readable storage medium storing a program for performing the method By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A substrate transportation path is determined by first determining a trajectory of a first straight line passing through a start point, calculating a trajectory of a circular arc in contact with the first straight line, calculating a trajectory of a second straight line in contact with the circular arc and passing through the end point, then, if the position of the end point is changed, re-calculating the second straight line as a straight line passing through the changed end point and in contact with the circular arc, and allowing the center of the substrate holding unit to move on the first straight line, and then, move on the circular arc from a first contact point, followed by moving on the second straight line from a second contact point so as to reach the end point.

app Vehicle detection apparatus By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A vehicle detection apparatus comprises an other-vehicle detection module configured to detect points of light in an image captured by a vehicle to which the vehicle detection module is mounted and to detect other vehicles based on the points of light, a vehicle lane-line detection module configured to detect an vehicle lane-line in the captured image, and a region sectioning module configured to section the captured image based on the detected vehicle lane-line into an own vehicle lane region, an oncoming vehicle lane region, and a vehicle lane exterior region. Other vehicles are detected by the other-vehicle detection module by detecting points of light based on respective detection conditions set for each of the sectioned regions. Full Article
app Method, system, and apparatus having near field communication (NFC) chip with configurable memory that is updatable via a host processor By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A wireless media player and a related system and methodology are disclosed. One aspect of the wireless media player system pertains to a virtual connector system, apparatus, and method for the automatic establishment of wireless connectivity with other electronic devices. In one embodiment, the media player device employs the use of integrated Radio Frequency Identification (RFID) technology to exchange communication settings, media capability, and other parameters with an external device that also has integrated RFID technology. The automatic exchange of settings and other information via a proximity-based RFID data exchange allows a media player to quickly establish a secure communication link with another device via a commonly supported wireless protocol such as Ultra Wideband (UWB) or Bluetooth. Another aspect of the media player system pertains to a method of using the captured media capability of the connecting device to customize certain menu options and software parameters in the media player.
