According to the National Sleep Foundation, more than 18 million American adults have obstructive sleep apnea (OSA). OSA occurs when the back muscles of the throat relax while sleeping, causing the airway to narrow, resulting in snoring. These muscles could also completely block the flow of air to the lungs.
There are really three sides to proper data security. The first step is ensuring that new employee accounts are created with the proper access rights when an employee joins the organization. The second is making sure those access rights remain accurate during the employee’s tenure, and the third is revoking all access rights when the employee leaves.
The “TD” (Time Domain) flavor of LTE can no longer be viewed as a niche technology exclusive to China. Other countries worldwide, including India and Sweden, are embracing TD-LTE for their broadband wireless access rollouts. Before long, close to half the world’s population will be within reach of a TD-LTE network. India will have a full commercial service ahead of its northern neighbour, China.
The byproducts of Moore’s law have increased the performance and reduced the cost of electronic products across every industry for more than half a century. The development pace and proliferation of mobile devices today have leveraged Moore’s law, growing at a projected 24.9% CAGR for 2011 – 2017 (ovum.com, May 3, 2012).
The next advance in weather forecasting may not come from a new satellite or supercomputer, but from a device in your pocket. University of Washington atmospheric scientists are using pressure sensors included in the newest smartphones to develop better weather forecasting techniques.
Operators are looking to deploy small cell technologies as quickly as possible to generate revenue, offload data traffic, and leverage the existing macro network efficiency. These small portable platforms have limited hardware, memory, and CPU speed so operators need real-time application software to manage their performance, stability, scalability, and efficiency to ensure customer satisfaction.
System-Level Design and Verification of Wireless Embedded System to Meet Global Demands Using a Mixed Domain OscilloscopeJanuary 10, 2013 3:16 pm | by Faride Akretch, Technical Marketing Manager, Tektronix | Comments
Designing and implementing wireless systems so they can be used in different geographic regions around the world represents a significant challenge. Wouldn’t it be nice if everyone all agreed on the use of frequency, modulation type, power levels, and bandwidth?
What are some key considerations when selecting a high frequency circuit board material? Art Aguayo, Sr. Market Development Manager, Rogers Corporation Determine the dielectric constant needed and the dielectric loss desired. There are many factors around these properties that are rarely captured in a data sheet or software property table, yet are very important in the selection of high frequency materials.
Wireless sensors are applicable for a variety of applications, whether it be smart cities (smart parking, smart lighting, waste management), industrial control (M2M applications, indoor air quality, temperature monitoring), eHealth (fall detection, patient surveillance, ultraviolet radiation) and many more.
Energy harvesting wireless technology monitors and controls large-scale industrial plant facilities By Jim O’Callaghan, President of EnOcean Inc. Essential factors for the success of a business include production up-time and process machinery efficiency. Real-time monitoring of machinery makes it possible to detect and prevent equipment failure proactively.
In wireless systems, interference in the wireless channel can be quite problematic, degrading the reception of desired signals. It can originate from a variety of intentional, unintentional and incidental radiators and occurs in both licensed and unlicensed spectrum. With the growing scarcity of radio frequency spectrum and ongoing efforts to improve its utilization for the highest capacity and performance (e.
Brainstorm : How does the future of the wireless industry affect M2M communications? Dr. Erez Manhaimer, VP of Marketing, Alvarion As the demand for M2M communication grows, the wireless industry provides a common, mature IP infrastructure that can be deployed cost effectively making it an enabler of M2M communications.
Brainstorm : With the advent of wireless equipment designs being challenged for high reliability demands, what connectivity considerations must be taken? Today’s process infrastructure requires practices and equipment that keep operations functioning regardless of environmental conditions or other potentially harmful disturbances.
Where in the design cycle is it best to spec in a timing device, and why? Ramon Cerda, Vice President of Engineering , Crystek Corporation The short answer is; as soon as possible. Most, if not all timing devices should be treated as long lead-times items. If the crystal oscillator manufacturer does not have your particular frequency and/or specification requirement in stock, it can take many weeks before they can deliver the timing device.
It’s not uncommon to look at a discrete component’s datasheet and think that the manufacturer might be willing and able to tweak the performance for you in exchange for a little NRE and an up charge on the standard price. But a MMIC is another story. Or is it? Like so many things, advanced government and space programs have been influencing the MMIC market for years.
