Abstract: A new approach is proposed that contemplates systems and methods to enable an individual to complete a financial transaction by swiping a magnetic stripe card through a card reader connected to a mobile device. The size of the card reader is miniaturized to be portable for connection with the mobile device. The card reader is configured to reliably read data encoded in a magnetic strip of the card with minimum error in a single swipe and provide a signal that corresponds to the data read to the mobile device, which then decodes the incoming signal from the card reader and acts as a point-of-sale device to complete the financial transaction. Such an approach enables a person to become either a micro-merchant (payee) or a buyer/customer (payer) without having to purchase expensive card reader devices or software.

Abstract: A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module (4) also contains a needle guard (42) that locks after dose delivery. The needle guard (42) prevents accidental needle sticks before and after an injection. A locking collar (66) rotates during use as an inner protrusion (12) follows three paths (14, 15, 16) of a track (13) located on the outer surface of a body housing (10). When the inner facing protrusion (12) is in the third path (16), it encounters a hard stop and a rotational bias that locks the guard (42) from further retraction and thus covers the sharp distal end of the needle (3).

Title: Methods and systems for improved drilling operations using real-time and historical drilling data
Inventor: MARX TRENT
IPC: E21B44/00
Filed: 2012-10-31
Abstract: Methods and systems are described for improved drilling operations through the use of real-time drilling data to predict bit wear, lithology, pore pressure, a rotating friction coefficient, permeability, and cost in real-time and to adjust drilling parameters in real-time based on the predictions and prompt to change the drill bit in accordance with the real-time bit wear prediction and historical data. The real-time lithology prediction is made by processing the real-time drilling data through a multilayer neural network. The real-time bit wear prediction is made by using the real-time drilling data to predict a bit efficiency factor and to detect changes in the bit efficiency factor over time. A pore pressure estimation is made by including expected analogous values located on fused trend lines generated from the trends in historical data of analogous wells. The methods and systems also include determining various downhole hydraulics parameters and a rotary friction factor.

Abstract: Systems, methods and apparatus for radial amplitude assisted transfer (RAAT) in mass spectrometers are provided in which ions for RAAT are accelerated along a longitudinal axis of a mass spectrometer in order to decrease the magnitude of excitation energy of radially excited ions in an ion trap that allows the radially excited ions to exit the ion trap. Hence, the radially excited ions exit the ion trap with reduced radial energy thereby decreasing the exit angle of the radially exited ions from the ion trap. Furthermore, combined forces on the ions are such that radially excited ions exit the ion trap while unexcited ions remain in the ion trap.
