Inertial navigation system

An inertial measurement system for a spinning projectile comprising: a first, roll gyro to be oriented substantially parallel to the spin axis of the projectile; a second gyro and a third gyro with axes arranged with respect to the roll gyro such that they define a three dimensional coordinate system; a controller, arranged to: compute a current projectile attitude from the outputs of the first, second and third gyros, the computed attitude comprising a roll angle, a pitch angle and a yaw angle; calculate a roll angle error based on the difference between the computed pitch and yaw angles and expected pitch and yaw angles; provide the roll angle error as an input to a Kalman filter that outputs a roll angle correction and a roll rate scale factor correction; and apply the calculated roll angle correction and roll rate scale factor correction to the output of the roll gyro; wherein the Kalman filter models roll angle error as a function of roll rate and one or more wind variables. The system provides improved calibration of the roll axis rate gyro scale factor, e.g. of an IMU fitted to a rolling projectile. A separate process (an Euler angle filter) is used to calculate an estimate of the roll angle error without the use of the Kalman filter and is then provided as an input to the Kalman filter which can then operate in a stable manner. The filter can be configured to estimate and correct for crosswind effects which would otherwise significantly degrade performance.

Micro-arrayed organization of transcription factor target genes

The following invention outlines methodologies for the construction and utilization of transcription factor direct target gene microarrays of both DNA and corresponding protein/peptide target origin. The technology entails the array/microarray annotation and organization of transcription factor direct loci and corresponding protein products identified through modified and improved versions of chromosomal immunoprecipitation (CHIP) and molecular cloning procedures. It allows for the formulation of physiologically directed arrays which result in a thorough, focused characterization of the genetic and biochemical regulation occurring within a give population of cells or a given tissue. Arrays and microarrays of direct targets for any given transcription factor created utilizing this technology are substantially more clinically relevant for purposes of medical diagnostics and patient prognostics than conventional microarrays due to the physiologically focused nature and the transcription factor targets. In addition, the characterization and array organization of transcription factor target protein products and the assessment of their interactions with other proteins and/or small molecules is of critical importance for the purposes of understanding cellular and ultimately the design of therapeutics for human anomalies.

Printing head, printing device and printing method for rapid forming of metal piece

InactiveCN105112965ATo overcome the shortcomings of low printing efficiencyFast printAdditive manufacturing apparatusEtchingEngineering
The invention discloses a printing head, a printing device and a printing method for rapid forming of a metal piece. The printing head comprises a body, a plurality of nozzles, a first electrode and a second common electrode. When the printing head is in the working state, electroplate liquid is sprayed out through the multiple nozzles and sequentially passes through the first electrode and the second common electrode. The printing device is provided with the printing head. According to the printing method, when electrochemical deposition or electrolytic etching is conducted on the electroplate liquid, the electroplate liquid is electrified and is directly sprayed onto a position needing to be printed; in the position which does not need to be printed, the electroplate liquid deflects when flowing through a deflection electric field by changing the electrical characteristic of the electroplate liquid, and the electroplate liquid is prevented from being sprayed onto the position which does not need to be printed. By the adoption of the printing head, the printing device and the printing method for rapid forming of the metal piece, the defects that a three-dimensional (3D) printer for the metal piece in the prior art is low in printing efficiency and low in precision are overcome, and rapid, high-quality and high-precision printing of 3D metal pieces is achieved.
