Controlled vehicle acceleration method using user-responsive feedback

Patent Identifier: 
8374765

A method includes selecting, from a data table containing a plurality of weighted independent variable columns and rows, where each of the columns represents an independent input variable feature and each row represents a set of stored independent input variables and a corresponding stored dependent variable, a row that best matches received sensor independent input variable data from at least one vehicle sensor, causing a vehicle accelerator to gradually accelerate a vehicle to a vehicle acceleration level corresponding to the stored dependent variable of the selected best match row, and modi

Covalent attachment of peptides and biological molecules to luminescent semiconductor nanocrystals

Patent Identifier: 
8378075

A method for covalent attachment of peptides to luminescent quantum dots or other inorganic nanoparticles. The first step in the method involves functionalizing at least a portion of a surface of the quantum dot or nanoparticle with one or more materials having at least one reactive functional group therein. Subsequently, a peptide having a reactive functional group is reacted with at least some of the quantum dot or nanoparticle reactive functional groups to covalently bond at least some of the peptide to the quantum dots or nanoparticles.

Deployable magnetometer

Patent Identifier: 
8378671

Cost-effective compact magnetometers can be deployed across large ocean areas to record magnetic field strengths. Each magnetometer has a canister containing a magnetometer sensor at its upper end to detect magnetic field strengths of magnetic influence sweep systems and provide representative data signals. Each magnetometer also has sensors to collect data representative of the orientation of the magnetometer as well as temperature and depth to aid in post operational evaluation of the gathered magnetic strength data.

Integrated angle of arrival sensing and duplex communication with cats-eye multiple quantum well modulating retroreflector

Patent Identifier: 
8379286

A modulating retroreflector system includes a modulating retroreflector having a plurality of multiple quantum well modulator pixels and at least one transimpedance amplifier. The transimpedance amplifier receives a photocurrent generated by at least one of the plurality of modulator pixels. Each pixel is capacitively coupled to a current driver, which applies a high frequency digital electrical signal to the pixel when the voltage at the output of the transimpedance amplifier exceeds a threshold value.

Patent Identifier: 
20130020672

A method and an electronic device structure comprising at least one access lead to adapted to be connected to an electrical circuit; at least one substrate region; at least one semiconductor die positioned on the substrate; the at least one semiconductor die being operatively connected to the at least one access lead; a dielectric region extending below the at least one semiconductor die; the dielectric region being formed by creating a cavity in the at least one substrate region; whereby the dielectric region operates to reduce electric field stresses produced by the at least one semiconducto

Measurement of small accelerations by optical weak value amplifcation

Patent Identifier: 
20130027710

An accelerometer instrument is provided for measuring acceleration. The instrument includes a laser, a Mach-Zender interferometer (MZI), a mechanical spring, a detector, a camera, and an analyzer. The laser emits a coherent light beam of photons. The MZI includes first and second beam-splitters along with first and second mirrors. The first mirror has an established mass m and connects to the spring for vibrating substantially perpendicular to its reflection plane. The mechanical spring has an established spring constant k.

Circular Antenna Array for Satellite Communication Interference Rejection

Patent Identifier: 
20130035052

An antenna array system and method is provided for reducing interference from a source moving relative to the antenna array system. The antenna array system includes a receiver and a plurality of antenna array elements arranged in a planar array. Each of the plurality of antenna array elements is in electrical communication with the receiver and in a locationally fixed position relative to the receiver. The plurality of antenna array elements receives a desired signal and interference from the source moving relative to the antenna array system.

Self diagnostic armor structure

Patent Identifier: 
8333140

A unit of modular armor. The module has a box-like, optically opaque outer shell of ballistic-protection material enclosed to exclude light from the module's interior. The shell contains transparent armor plates and the shell contains a self-diagnostic system for ascertaining whether the plates have been damaged. The self-diagnostic system includes a first PC board disposed along first edges of the plates, the board being divided into strips on which are mounted rows of lights.

Integrated coaxial transducer with alternating insulators

Patent Identifier: 
8334460

A coaxial transducer that uses lead zirconate titanate ceramic or other suitable material as an isolator between the conductors in a coaxial cable to transmit acoustic power at useful levels. The lead zirconate titanate ceramic is diced into thin disks and placed in between spacers made of much stronger insulating material. The coaxial cable is then integrated into a conventional double-armored steel tow cable with a typical diameter of 1_.

Vessel of interest communications system

Patent Identifier:
