Abstract: A receipt capture device can collect transaction information from transactions conducted at a point of sale system by capturing receipt data transmitted from the point of sale system for the purpose of printing receipts at an external receipt printer. The receipt capture device can then send the collected receipt data to an online system for analysis. At the online system, received receipt data can be decoded from the printer-readable format it is transmitted in and used to enhance the online system's understanding of transactions occurring at a retailer associated with the point of sale system. For example, the online system can determine an approximate inventory of items available at purchase at the retailer by aggregating items recently purchased in transactions at the point of sale system.

Abstract: Systems and methods for normalizing the control parameters associated with trading algorithms, providing analytic data to traders in discrete time intervals to assist in the analysis of trading performance, and providing crossing opportunities to orders that have been committed to a trading algorithm but have not yet been executed, are provided. A dashboard to allow a trading professional more effective use of multiple algorithms can be created. Parameters associated with multiple algorithms can be normalized and tuned rapidly from a single user interface. Trading performance can be reviewed in discrete time intervals and execution venues. Traders can review a performance score for a trading algorithm and select an algorithm based in part on their commission budget. Block trading opportunities can be available with a crossing engine or external ATS.

Abstract: An apparatus and method for delivering oxygen to a nasopharynx and withdrawing exhale gas from the nasopharynx to a carbon dioxide monitor. In one embodiment, the apparatus can comprise one or more tubes and an airway fitting forming an airway. The airway fitting can be configured to engage at least one of the tubes and maintain the one or more tubes within the airway, and to provide an outlet to the atmosphere for the airway. In another embodiment, the tube might be in fluid communication with a junction that can direct oxygen from an oxygen supply through the tube and exhale gas from the tube to the carbon dioxide monitor. Further, the tube might comprise an outer tube and an inner tube.

Abstract: A CMOS power saving comparator/inverter circuit includes a complementary differential amplifier, one input of which is coupled to a voltage input. Another input of the complementary differential amplifier is coupled to a voltage reference circuit which includes two relatively high value resistors coupled in series between a P-channel MOSFET coupled to the positive voltage conductor and N-channel MOSFET coupled to the ground voltage conductor. An output of the differential amplifier is connected to an input of a CMOS inverter having its output connected to an output of the comparator/inverter circuit. The transition point, defined as the value of input voltage at which the output voltage is equal to one-half of the supply voltage, is virtually independent of the P-channel and N-channel threshold voltages. The transition point is much sharper than the transition point for a conventional CMOS inverter, and much less dependent upon various manufacturing parameter variations.

Abstract: A multi-state CMOS synchronous binary counter is implemented utilizing a CMOS transmission gate look-ahead carry circuit requiring only a fraction of the area required for AND or NAND gate carry structures.
