Methods, apparatuses, and systems for operating light emitting diodes at low temperature
Light-emitting diodes (LEDs) generate light more efficiently than high-intensity discharge lamps or high-intensity fluorescent lamps. Driving a series of LEDs with a constant-voltage primary supply and a low-voltage LED driver keeps efficiency high. Unfortunately, LED forward voltage varies as a function of temperature: at low temperature, the forward voltage rises. Placing the LEDs in series magnifies the forward voltage increases. This makes it difficult to drive a series of LEDs at low temperature with a constant-voltage supply because the forward voltage can exceed the power supply voltage. To account for this behavior, an exemplary LED lighting fixture includes a “bypass” circuit that, when engaged, effectively removes at least one LED from each series string of LEDs to bring the total forward voltage below the power supply voltage. The low-voltage driver circuit monitors temperature, and engages the “bypass” circuit when necessary to ensure that DC voltage is not exceeded. |

Instant simultaneous messaging
The present invention relates to a process that enables nearly real-time exchange of instant simultaneous messages between the users of a digital communication network. Instant Simultaneous Messaging enables “real” simultaneous exchange of contents between the users over a subject. This simultaneous exchange ensures that each user can access other users' contents with exactly the same order, e.g. privilege. Therefore, none of the users within a simultaneous conversion can be affected by other users' messages. The purpose of instant simultaneous messaging is to heal herd mentality by enforcing novelty/originality to the contents that are exchanged between the users. Therefore, while users are communicating over a subject simultaneously, a given user can not learn or get affected by other users' opinions before disclosing its own. The present invention provides a method and its apparatus for Instant Simultaneous Messaging between a sending user and a target user over a digital communication network. |

Methods, systems, and computer program products are provided that address issues related to data privacy by enabling users to elect various levels of data sharing. A user of a user device is enabled to indicate their comfort level with sharing, transmitting, or otherwise exposing individual activity records (data entities) with respect to various activity categories. The exposure of activity records may be controlled with respect to on-device and off-device components. Furthermore, privacy profiles may be automatically generated for the user, and the privacy profiles may be automatically activated in corresponding situations. |

Image processing apparatus and control method thereof
An image processing apparatus and control method are provided. An image processing apparatus including: a storage configured to store data which is divided into a plurality of units of code; a random access memory (RAM) configured to be loaded with the data; a central processing unit (CPU) configured to execute the data; and a storage controller configured to read a requested unit of code from the storage in response to receiving a request from the CPU for the unit of code to be currently executed, and load the read unit of code to the RAM so that the unit of code can be processed by the CPU, wherein the storage controller performs validation with regard to the unit of code when reading the unit of code from the storage, and loads the unit of code, when the validation passes, to the RAM. |

Enabling enforcement of licensing terms in distributing content in containers by including a key in the container containing the pertinent licensing terms
A method, system and computer program product for enforcing licensing terms when distributing content via a container image running in a container. Upon receiving a request for a service from the container by the isolation code, where the isolation code limits, accounts and isolates resource usage of process groups, the commerce code application programming interfaces (APIs) of the isolation code read a key of the container. The key contains licensing terms applied to the component(s) (e.g., applications) of the container. The commerce code APIs will then confirm that the container is in compliance with those licensing terms. If the container is in compliance with the licensing terms, the container will be allowed to execute. Otherwise, the container will be prevented from executing. In this manner, the commerce code APIs can enforce the licensing terms, including restrictions and enforcement of payment to the licensor upon distributing content in the container. |
