Design of a multi-functional communication interface for Low power applications

This article describes implementation possibilities of specialized microcontroller peripherals, as hardware solution for Internet of Things (IoT) low-power communication, interfaces. In this contribution, authors use the NXP FlexIO periphery. Meanwhile, RFC1662 is used as a reference communication standard. Implementation of RFC1662 is performed by software and hardware approaches. The total power consumption is measured during experiments. In the result section, authors evaluate a time-consumption trade-off between the software approach running in Central Processing Unit (CPU) and hardware implementation using NXP FlexIO periphery. The results confirm that the hardware-based approach is effective in terms of power consumption. This method is applicable in IoT embedded devices.

Sensory networks are part of a solution to monitor the required physical variables in the area of interest. Their type, the used communication protocol, plays an important role in the parameter of their complexity. One of the economical solutions is the usage of a 1-wire communication network that requires only 2 physical wires. The individual sensors or the nodes of the communication network are connected in parallel. The goal was to design and implement a universal low-power 1-wire bus module with a fully implemented 1-wire standard. As a platform for the development of such module, STM32-based microcontroller was chosen. The main advantage of this solution is the ability to utilize a sensor from a large variety of available sensors with a standardized communication interface. Our solution of the universal 1-wire module provides a single interface for sensors with different communication interfaces, while it still communicates with the standard 1-wire bus controller.

Treatment Research

Abstract Primary progressive aphasia (PPA) is a relatively new diagnostic entity, for which few behavioral treatments have been investigated. Recent work has helped to clarify the nature of distinct PPA variants, including a nonfluent variant (NFV-PPA), a logopenic variant (LV-PPA), and a semantic variant (SV-PPA). This paper reviews treatment research to date in each subtype of PPA, including restitutive, augmentative, and functional approaches. The evidence suggests that restitutive behavioral treatment can result in improved or stabilized language performance within treated domains. Specifically, sentence production and lexical retrieval have been addressed in NFV-PPA, whereas lexical retrieval has been the primary object of treatment in LV and SV-PPA. Use of augmentative communication techniques, as well as implementation of functional communication approaches, also may result in improved communication skills in individuals with PPA. The ideal treatment approach may be one that combines restitutive, augmentative, and functional approaches to treatment, in order to maximize residual cognitive-linguistic skills in patients. Additional research is warranted to determine which modes of treatment are most beneficial in each type of PPA at various stages of severity.

The Way

Abstract. Power facilitates goal pursuit, but how does power affect the way people respond to conflict between their multiple goals? Our results showed that higher trait power was associated with reduced experience of conflict in scenarios describing multiple goals (Study 1) and between personal goals (Study 2). Moreover, manipulated low power increased individuals’ experience of goal conflict relative to high power and a control condition (Studies 3 and 4), with the consequence that they planned to invest less into the pursuit of their goals in the future. With its focus on multiple goals and individuals’ experiences during goal pursuit rather than objective performance, the present research uses new angles to examine power effects on goal pursuit.
