System and Methods for an Automated Sun Glare Block Area and Sunshield in a Vehicular Windshield

InactiveUS20100094501A1Darken minimum areaClear and unobstructed viewAntiglare equipmentDigital data processing detailsEngineeringMotorized vehicle
A system and methods for the automated display of a borderless sun glare block area and sunshield in a windshield, which can be made of electrochromatic glass, in a motor vehicle driven at any time and at any location on earth is presented. The first method, which accurately calculates the precise position of the sun glare block area, is based on the apparent solar position, the direction of travel relative to the true North, the slope of the road, the windshield tilt angle, and the dynamic position of the driver's eyes. It uses sets of different formulas depending on the position of the sun glare on the windshield and the slope of the road. The second method calculates the changing opacities of the borderless sun glare block area, whose opacity decreases from its center to its edge and matches that of the sunshield, based on the ambient light intensity.

Buoyant airbarge and spinnaker sail combinations for generating electric power from wind

Systems for generating electric power from wind are disclosed, which use buoyant aircraft and spinnaker sails to generate very large pulling forces, which will be used to drive electric generators. The buoyant aircraft, referred to as “airbarges”, will have large, wide, and flat shapes which combine various traits of kites, manta rays, and “flying wing” aircraft. They can be flown “nose up” during the pulling stage of each power cycle, and “nose down” during retrieval. Spinnaker sails are comparable to horizontal parachutes, with tethering systems that will enable them to be pulled back to a starting location in a “luffing flag” or “closed umbrella” configuration. Because of various factors, spinnaker sails can generate much greater power output and operating efficiency than 3-blade wind turbines. “Webbing sails” made from interwoven straps also are disclosed, which can be used even in extremely high winds.

Method for elliptic curve scalar multiplication

The method for elliptic curve scalar multiplication may provide several countermeasures to protect scalar multiplication of a private key k by a point P to produce the product kP from power analysis attacks. First, the private key, k, is partitioned into a plurality of key partitions, which are processed in a random order, the resulting points being accumulated to produce the scalar product kP. Second, in each partition, the encoding is randomly selected to occur in binary form or in Non-Adjacent Form (NAF), with the direction of bit inspection being randomly assigned between most-to-least and least-to-most. Third, in each partition, each zero in the key may randomly perform a dummy point addition operation in addition to the doubling operation. The method may be implemented in software, smart cards, circuits, processors, or application specific integrated circuits (ASICs) designed to carry out the method.

Apparatus and method for aerodynamic wing

Aerodynamic wing to propel a broad range of transport means, principally sail craft. The wing provides a single layer kite structure capable of flying without surface discontinuity, bridles, or rigid or semi-rigid structure. All stresses within the wing are converted into pure tension and transferred through the wing surface outward to attachment lines. The wing shape defines a large diameter self-supporting rolled over leading edge of an airfoil and the wing profile approaching the trailing edge exhibits increasing convexity. The wing is useful to propel, or supplement propulsion to, transportation means.

Self-healing analog-to-digital converters with background calibration

Calibration of an analog-to-digital converter (ADC) is accomplished via a reference comparator, a first and second multiplexer (MUX), and a finite state machine (FSM). By sampling an analog input with the reference comparator and comparing the results with those of the ADC using the FSM, all the comparators in the ADC can be calibrated without interrupting the ADC's normal operation. The first MUX provides a same reference voltage to the reference comparator as a comparator selected for the calibration, and the second MUX provides the FSM with the output of the selected comparator. The FSM then performs a comparison of the reference comparator and the selected comparator, extracts the polarity of the mismatch, and updates the contents of a memory with the extracted polarity. An offset control in the selected comparator receives a signal corresponding to the extracted polarity stored in the memory and injects offset current into the comparator.

Transistor substrate, display device, and method of manufacturing transistor substrate and display device

A device has a first transistor and a second transistor wherein a channel length direction of the first transistor extends along a first direction and a channel length direction of the second transistor extends along a second direction intersecting the first direction, and the second transistor is formed on a same substrate as the first transistor. A first channel region and a second channel region are formed in semiconductor layers which are simultaneously formed and a mobility of the semiconductor film has an anisotropy in the first and second directions. With this structure, transistors having different mobilities can be obtained while using the semiconductor films formed on the same substrate and from a same material. For example, it is possible to form a transistor in which a high resistance is required using a semiconductor layer of the same characteristics as that in a transistor in which a high speed operation is desired, on the same substrate and with a minimum area.

Spark plug

There is provided a spark section (80) of needle-like shape protruding from an inner surface (33) of a ground electrode (30) to define a spark gap between the spark section and an electrode tip on a center electrode. The spark section (80) has a noble metal member (81) and an intermediate member (86) joined to each other. The materials of the noble metal member (81) and the intermediate member (86) are selected in such a manner that the thermal conductivity of the intermediate member (86) is lower than that of the noble metal member (81). This limits heat radiation through the heat radiation passage from the noble metal member (81) through the intermediate member (86) to the ground electrode (30) so as to maintain the noble metal member (81) at a higher temperature than conventional types and reduce a quenching effect of the noble metal member (81) on a flame core generated in the spark gap for improvement in ignition performance.

Non-linear common coarse delay system and method for delaying data strobe

A non-linear common coarse delay system and method for delaying a data strobe in order to preserve fine delay accuracy and compensate PVT (Process, Voltage, and Temperature) variation effects. A common coarse delay and a fine delay can be initialized to a quarter-cycle delay for shifting a read output DQS (Data Queue Strobe) associated with a memory device in order to sample a read output DQ (Data Queue) within a physical layer. The fine delay can be programmed from minimum to maximum delay with fixed linear increments at each delay step in order to determine the resolution and accuracy of the delay. An optimum delay size of both the coarse and the fine delay can be determined based on an application slowest frequency of operation. A spare coarse delay and a functional coarse delay can be trained in association with a spare fine delay and the functional fine delay can be updated in order to monitor the process, voltage, and temperature variation effects.
