Seiko Alarm Clocks’ Most Convenient & Accurate Clock to Date – The Global Atomic Travel Alarm Clock

My first idea of Seiko alarm clocks is that they are nice alarm clocks with features from 5-minute snooze rings with gentle tones to highly precise time keeping. But with more demands of travel alarm clocks, this competitive brand crafted a clock using the latest advancement in technology that will solve most travelers’ demands with traveling alarm clocks.

Over the past one hundred years, Seiko has developed cutting-edge timekeeping technology with constant innovation. Due to their unmatched precision with their alarm clocks, there’s no alarm clock brand that shouts accurate to the point. Now, Seiko ventures into atomic travel alarm clocks with their Global models.

This new Seiko Global Atomic Travel Alarm keeps time perfectly regardless of your location without resetting due to factors like time zone change, thus it is now more convenient that with ordinary alarm clocks around. The clock’s radio wave technology interprets the signal to automatically reset itself to correct the lock time. Thus, it automatically adjusts with time zone change, leap year, or the Daylight Savings Time. For a tourist or traveler, this eliminates all the confusion with time keeping.

This travel alarm clock utilizes state-of-the-art technology by picking up radio waves signals from atomic time transmitters. So whether you are in the United States, Japan, or United Kingdom, it keeps time with great accuracy.

Seiko radio controlled alarm clocks are so accurate because of their ability to receive radio signals from the standard of the international time scale, the cesium atomic clock maintained by the National Institute of Standards in Fort Collins, Colorado. In fact, this same clock in Colorado is the most accurate clock in the world. This radio wave technology is so precise that it is proud of keeping time at the variation of within one second in a million years.

The design of the Global Atomic Travel Alarm Clock is sleek, self-standing chrome and titanium colored acrylic case. It is very compact and fits perfectly on anyone’s luggage or can stand alone in your night stand or desk at home. It has legible digital display with hour, minute, and second. It also has day and month display too. Furthermore, it adds luminescent lighting for easy viewing at night. Packable in a travel bag due to handy size and shape, the nice sleek design is a great plus for Seiko’s Global alarm clock.

The ascending beep alarm with snooze is also a handy feature so that it does not shock you instantly. It also has automatic alarm stops after 1 minute. Additional features of this travel clock are: dim amber light, calendar, and thermometer.

Whether on my bed stand at home or while in another country, this travel alarm clock is easy to use and read with its user-friendly layout. Now, you will never be able again with your flight as you oversleep with that leisure trip. Therefore, it makes the ideal gift for your traveling dad.

Texture Analyzer – Accuracy, Resolution and Precision Explained

Systems work on the principle of supplying a large range of easily interchangeable load cells, which allow the users of texture analyzers to choose specific capacities relevant to the texture measurement forces they wish to measure.

Texture Analysis accuracy

Texture analysis instruments have the ability to measure load or distance to the absolute true and correct value. Generally defined as a percentage of the full scale range of the measuring device, where the manufacturer states the ability of the instrument to report registered load or distance correctly in relation to a calibrated standard.

Some texture analyzers intelligent load cells operate to 0.1% accuracy of full-scale capacity. If you are using a 10N (1.0kgf) capacity we can expect a margin of error (or inaccuracy), no greater than, +/-1gf. Therefore if the value reported by the instrument for a force is 300gf we can expect our true reading to be between 299gf and 301gf

Resolution is the smallest unit of measure or the smallest change that can be displayed or recorded by an instrument referred to as granularity

This characteristic can be expressed as a percentage or in actual units and is highly influential on the level of accuracy that the instrument can measure at. For Example, A load cell can only operate to 0.1% accuracy of full scale, say +/-1gf therefore the potential error must always be much greater than the 0.15gf resolution that the unit will measure individual changes.

Some texture analyzers have a resolution of 1 part in every 6,500. To calculate this in real terms we divide the capacity of the load cell by 6,500. For Example 1000gf capacity load cell 1,000/6,500 = 0.153gf measurement increments for load, This effectively means that a new load will increment every 0.153gf e.g. For position measurements. A data resolution of 0.0025 mm in its travel span. In other words, there is an event signal from the positional sensor for every 0.0025 mm of movement. Data is recorded at this level of resolution but only displayed at a resolution level of 0.01 mm of travel.

Precision is how reproducible or close identical measurements will be reported as a percentage of full scale.

This is extremely difficult to demonstrate practically as all samples will be slightly different. If calibrated weights are used we can anticipate that our repeatability will be directly a function of accuracy

DATA CAPTURE RATE:

Intelligent filter data from 16,000 down to 2,000 points per second. This enables texture analyzers to operate at a much higher data rate than competitor systems. This means that the load displayed is truer providing the user with a much greater number of “peaks” and “troughs” from trace, although this can be smoothed later within the software.

A high data capture rate is offered so that food technologists are able to collect all available information relating to the textural properties of their samples. This is of particular relevance with brittle foods where the micro fractures caused by the test probe entering or deforming the sample are of importance.

Simple three-point bend test on a cookie.

The brittle structure of the sample exhibits micro-fractures from the minute the test probe touches its surface. These fractures are clearly visible at the 2000pps data capture rate and allows the food technologist to obtain a full and detailed interpretation of the biscuits structure. Had the data been filtered to 500pps these initial fractures would have gone undetected and the food technologist would have potentially made an incorrect assessment of the biscuits fracture characteristics.

AMPLIFICATION OF LOADS:

Systems available to day can collect unfiltered force readings at 16,000 points per second using a 14 bit processor. Not following the principles of amplifying or digitally enhancing the raw data through averaging and calculation of new data points when measuring in the lower region of load cell capacity is a mistake. This is why it is recommend that the use of load cells which match the preferred range of measurement are used. It is often better to have more than one load cell to cover a variety of products.

It is important that you choose the correct load cell. Each load cell has a level of accuracy relating to its full scale measuring capability.

If you measure a very soft product such as cream cheese you will generate very low forces of around 2-3N. The +/- accuracy value means that if I use a 2500N load cell the potential instrumental error will be greater than the force one is wishing to measure.

SUMMARY

1. 10 load cell capacity options from 200gf to 255kgf capacity
2. Choose load cell capacity to match measured range ideally between 10 and 90% of the load cell’s capacity
3. Filter data post test to smooth peaks post test in software
4. Collect 2000 points per second of load, position and speed
5. Accuracy is measured as % of Full Scale. If Accuracy is not stated resolution is irrelevant as measurement will not be true
6. Load cell is calibrated over full range of capacity
7. No amplification of signal to improve accuracy and resolution below 10% of load cell capacity

Online Travel Guides Having a Heyday

As Online Travel has caught the fancy of the internet savvy travelers the online travel market is booming. No wonder that the online Travel is one of the fastest growing markets worldwide. India is also not left behind in this race as according to industry Pundits, Online Travel Market in India would be worth around US $ 6 Billion.

As a logical extension to such buoyancy, Travel Guides have shown a steady rising to move online and in the process fulfilling the needs of the niche readers. Both traditional print brands as well as purely cyber entities are slogging it out to grab the attention of this niche segment. The publishers of print brands after their initial reluctance have also started embracing the web and publish all their content online.
Travel Guides

Let’s take a look at what the Travel Guides offer. Travel guides have become a necessary tool for anyone who is thinking of vacation. A Travel Guide is full of helpful advice, precise information, good ideas etc besides being well-written, well laid out as well as well indexed.

These City centric guides provide information on all aspects of travel. You can get good information on How to Reach, Attractions, Excursions, festivals, History along with the various kinds of accommodations available like lodges, hotels, resorts and the bed-and-breakfasts. Convenient maps make it easy for the newcomers to exactly pinpoint any destination.

An ideal Travel guide should also briefly outline the recreational activities coupled with more mundane activities of life that can be done in a particular city. Another important aspect that is generally missed out is the public transport of the cities where a traveler lands up. A genuine Travel Guide is also supposed to give precise information of the state of public transport highlighting bus routes, Cabs and Auto fares.

Another important aspect of a City Guide is to have a semblance of balanced information. This is important because travel can be both for as well as business.

Pros and cons of Online Travel Guides

More and more people are into researching the internet as a result the Online Travel Guides have become quite popular as compared to their print counterparts. However both the two brands have their own set of advantages and limitations.

Online Destination Guides are successful in tapping user-generated reviews and provide the added advantage of E- Commerce options. So surf the web pages of the guide and book flights, hotels and other arrangements at one go directly through the site. Another great feature of the Online Guides is that there is ample scope for value addition. For example Indian railway has planned a new train to connect Amritsar to Kasargod. This information can be easily updated in the Guide for the travelers to see.

As Hotels and rental agencies change their rates according to season and local competition, online travel guides also offer a dynamic lot of packages based on such variances. However coming to the flip side of it is very difficult to find Online Travel guides bereft of commercial influences. It is not uncommon to see many sites that are setup to merely attract the potential customers to a particular establishment, or sites giving reviews by travelers may not be wholly independent.

To conclude Online Travel Guides have become a very good way to gather information about smaller cities of India that has an immense tourism potential but often neglected. For example the whole of North east, Northern Kerala neglected as a tourist spot over the years have seen good tourist influx thanks to the ubiquitous travel guides.
