| 20110062932 | DC/DC CONVERTER HAVING A FAST AND ACCURATE AVERAGE CURRENT LIMIT - In order to overcome the three main obstacles to obtaining a fast and accurate average current limit in a DC/DC converter, three distinct improvements are provided which can work in concert to achieve the goal. Each of the three parts comprises significant new improvements, and their use together to create an average current limit is also believed to be novel. The first improvement relates to providing a bias signal control configured to apply a variable DC bias signal to the compensation ramp signal generated in the DC/DC converter so that the compensating ramp signal is biased to zero at the end of each ON-time for each cycle so that the peak current limit is independent of the duty cycle of the pulse width modulation signal during current limit conditions. A second improvement relates to modulating the clamp voltage that establishes the peak current limit as a function of ripple of the inductor current for each cycle of the pulse width modulation signal so as to reduce or cancel the effect of the inductor ripple current on the average output current during current limit conditions. The third improvement relates to adjusting the frequency of the pulse width modulation signal during current limit conditions as a function of both the input voltage and the output voltage of the DC/DC converter. | 03-17-2011 |
| 20110063882 | ACCURACY OF A VOLT-SECOND CLAMP IN AN ISOLATED DC/DC CONVERTER - A novel system and methodology for providing a volt-second clamp.

The power switch is further controlled by a comparator that compares an input value supplied to its input with a variable reference value so as to prevent magnetic flux density of the transformer from increasing to an undesired level. The input value of the comparator is produced by a comparator input circuit as a function of the input voltage and an on-time of the power switch. A reference circuit produces the reference value that varies as a function of the input voltage. | 03-17-2011 |

| 20100236271 | Ice Management Apparatus - An ice making and delivery apparatus for making and delivering ice to different ones of a plurality of receptacle units is provided, in which ice delivered via a conduit to a diverter valve mechanism, is diverted from alignment with one ice discharge line to another, depending upon sensors in ice receptacles recognizing a level of build-up of ice in any given receptacle, for computer control of a gearmotor for moving the diverter valve from one position to another. Various controls are provided for preventing ice build-up, and for operating the diverter valve during a “dwell” period of ice movement in the conduit, as distinguished from a “push” period of ice movement in the conduit to the diverter valve. A force multiplication technique is employed for moving the diverter valve notwithstanding the presence of ice therein. | 09-23-2010 |

| 20100011842 | BIOCHEMICAL ASSAY METHODS - Biochemical Assay Methods. There is described a method for determining a value that allows the effect that a compound has on a target to be compared with the effect that another compound has on the target, which method comprises adding the compound, at a concentration which continuously varies with time, to a flow of the target. The method can be carried out using a microfluidic system. | 01-21-2010 |

| 20090063504 | Bi-directional replication between web services and relational databases - A method for bi-directional data replication between a Web Service application and a relational database are provided. Techniques of Enterprise Application Integration (EAI) and Extract Transform Load (ETL) technology are employed to create a relational database schema, load the schema, synchronize the structure and the content of the schema, and replicate changes in the content of the schema to the web services application. Optional advanced techniques to support reporting, legacy data migration, and integration with other applications are also provided. | 03-05-2009 |
| 20110082864 | Method for generating indexes for downloading data - A method for bi-directional data replication between a Web Service application and a relational database are provided. In an electronic communications network, a computer implemented method is provided for generating indexes of relationship fields by accessing the metadata of a remote web service. A plurality of records may be downloaded from the remote web service to a computer. The plurality of records may include metadata related to the identity of data fields involved in parent-child record relationships. An index may be built at least partially on the data fields involved in parent-child relationships. | 04-07-2011 |
| 20110082890 | Method of integrating applications with a network service application by creating new records in a relationship field - A computer-implemented method for integrating applications with a network service application is provided. A database management system automatically updates a local database of a computer with information contained within a remote database and an application is enabled to generate a new record in the local database with temporary values in the relationship fields such that the child records are logically related to one or more parent records by virtue of having the same relationship values. A new record is created by the web service for the parent record. When a changed value of the parent record's key is detected, a value of the key of relevant changed parent record is written into one or more local related record's relationship field. | 04-07-2011 |
