摘要:
A method relating to the calibration of tuneable lasers is described. The method provides for the provision of correct control currents so as to achieve each of desired output frequencies from the laser. The correct currents are determined by forming a matrix of the output characteristics of the laser at specific tuning currents and processing that matrix to determine stable operating points within the matrix.

The invention provides a method and system for compensating variations in tuning efficiency and power of a multi-section tunable laser diode. The invention comprises a means to obtain a set of values for a specific section of the laser diode and a means to normalise the values to compensate the non-linearities in the set of values, hence compensating for variations in the tuning efficiency for that particular section of the laser diode. The invention is advantageous in that it is generic and can be applied to several different types of lasers. A further advantage of the invention is that the mode width can be determined as well as the mode modulation of the tunable laser.

The disclosure according to some exemplary embodiments relates generally to an infrastructure for electronic records (e.g., electronic medical records (EMRs), electronic health records (EHRs), and personal health records (PHRs)). The infrastructure allows the use, for example, of the electronic records and other information sources to determine drug and other treatment prices that may differ from listed prices based on various factors, such as approved indication treated, the organization and/or individual responsible for payment, whether and what other drug or drugs are used as part of the treatment regimen, a diagnosis and treatment plan, and responses to treatment, among other factors. Advantageously, in some embodiments, systems and methods using the infrastructure allows patients to receive lower drug and treatment prices tailored to the patients' needs and can increase patients' access to drugs and other treatments.

Thermoformed or hot melt extruded pharmaceutical compositions containing an active pharmaceutical ingredient, acrylic enteric polymer and plasticizer are disclosed. Methods of making the same as well as various pharmaceutical dosage forms are also disclosed. In preferred aspects, a thermoformable mixture is in a powder form and includes an active ingredient, plasticizer, acrylic polymer and optional excipients which enhance the performance of the extrudate after being incorporated into a dosage form.
摘要:
A gas fuel injector includes a first header plate; a second header plate spaced downstream from the upstream header plate; and a plurality of venturi tubes arranged in rows and sealably secured to the first and second header plates. Each of the venturi tubes includes an inlet section, a throat section and an exit. The exit is shaped into a pattern that reduces space between each of the venturi tubes at the exit of each of the plurality of venturi tubes.
摘要:
The invention provides a method to compensate for degradation in a tunable laser and ensure its performance by tracking the degradation and adjusting the control information accordingly. This is accomplished by performing some measurements of the output of the tunable laser at an initial setup or calibration procedure. Then, by effecting a periodic repetition of these measurements and using a comparison between these two measurements the present invention provides for a compensation factor for the operating conditions, primarily in the form of a look up table of operating points of the laser. These measurements show how much the operating points of the laser have drifted over the period since the last set of measurements, which provide control informatIon to compensate for degradation in the laser.
