20090113919 | APPARATUS FOR COOLING GOODS - An arrangement suitable for cooling goods includes a controller with a database in which at least one time interval and one desired temperature value valid in the time interval is stored. A regulator function is implemented in the controller, via which function the temperature, returned to the controller via a temperature sensor, of a thermally insulated interior is regulated to the desired temperature value as a function of the time interval by activation or deactivation of a cooling device. Since the goods—for example filled drinks—are only available cooled during the time interval, energy is conserved and the emission of carbon dioxide thus also reduced. | 05-07-2009 |

20100250893 | BATCHED VIRTUAL MEMORY REMAPPING FOR EFFICIENT GARBAGE COLLECTION OF LARGE OBJECT AREAS - A method and system for batched remapping of virtual addresses for garbage collection in a large object area. A mapping from a table having a first set of virtual addresses and sizes of non-contiguous, page-aligned large objects in a large object area to a remapping table having a second set of virtual addresses is determined. In a single batch, a request is received that includes the second set of virtual addresses and requests a remapping of the large objects to the second set of virtual addresses. The second set of virtual memory addresses is validated. The large objects are remapped to the second set of virtual memory addresses according to the request. The remapping results in a compaction so that the large objects are contiguous in the large object area. The remapping does not require copying data in physical memory. | 09-30-2010 |

20150213521 | ADAPTIVE SOCIAL MEDIA SCORING MODEL WITH REVIEWER INFLUENCE ALIGNMENT - Online reviews present a wealth of information for consumers to consider when making purchase decisions. Consumers however, can be disadvantaged by an inability to determine the usefulness of reviews, the wealth of information thus providing marginal utility. Where consumers can establish an affinity or trust with a reviewer, the usefulness of a review can be vetted against the perspective of the consumer, assisting consumers in making purchase decisions with greater confidence and reliability. Social media further supports consumers by providing a convenient pool of reviewers with whom a consumer may already have pre-existing relationships or familiarity with, bolstering the ability of the consumer to establish an affinity or trust with the reviewer. An adaptive influence process provides a method for consumers to adapt such a collection of reviews, and tailor them to the consumer's own perspective to assist in making purchase decisions with greater confidence. | 07-30-2015 |
