A radio frequency IC device includes a radio frequency IC chip, a feeder circuit substrate, and a radiating plate. The feeder circuit substrate includes a feeder circuit that electrically connects to the radio IC chip and that includes a resonance circuit and / or a matching circuit including inductance elements. The feeder circuit substrate is bonded to the radiating plate, which radiates a transmission signal supplied from the feeder circuit and supplies a received signal to the feeder circuit. The inductance elements are arranged in spiral patterns wound in opposite directions and couple to each other in opposite phases. The radio frequency IC device is able to obtain a radio frequency IC device that is not susceptible to being affected by a usage environment, minimizes variations in radiation characteristics, and can be used in a wide frequency band.

A multi-function display controller that includes a source detector unit for determining if the source of an input stream is either film originated source originated or video source originated. A source converter unit for converting the input image stream to a common signal processing format is coupled to the source detector unit. Once converted to the common signal processing format, a determination is made if the input image stream is interlaced or non-interlaced (progressive scan). If the input image stream is interlaced, a de-interlace unit converts the interlaced signal to progressive scan using either motion adaptive or motion compensated de-interlacing techniques. It should be noted that in the described embodiment, motion vectors generated for use by the motion compensated de-interlace can be optionally stored in a memory unit for use in subsequent operations, such as motion compensated frame rate conversion or noise reduction (if any).

Throttles electronic devices based on compliance with rules for electronic communications such as emails, texts, or postings on social media sites. Rules may for example prohibit certain topics, language, or behaviors such as online bullying. If system detects a violation of the electronic communications rules, it may block access or reduce performance on one or more electronic devices as a consequence. In some cases, devices or selected apps or services may continue to function, but at a reduced level. Conversely the system may provide rewards for conforming with the rules. Throttling of devices may also depend on other factors, such as homework completion, test results, grades, and environmental conditions. Machine learning techniques may be applied to determine when electronic communications may violate the rules. For example, probabilistic topic models may be applied to determine the topics of electronic communications, and to assess whether these topics violate the rules.
