Tile – Find anything which is lost

Tile – Find anything which is lost

           We live in the world of gadgets and accessories. Accessories are a part of our daily life. Some of the accessories which we use in our day to day life are mobiles, laptops, bags,wallets, keys etc. It is a regular habit of people to misplace their accessory. The accessory is either found or lost. This happens to almost all people. It doesn’t matter whether we are in home, office or travel. e use accessories wherever we go. If you are a kind if guy/girl who misses or misplaces any product or accessory frequently. Here is the solution for it. Tile!!!, which is used to find the lost item.

Tile is a small Bluetooth device which is sized around 1.5cm square and 5mm thickness. Tile will be used along with iOS compatible devices to find the location of lost item. The Tile is kept with the accessory or item which we lose or misplace frequently. If we misplace the item, the iOS device will be able to detect the Tile if its in the range of 50ft to 150ft distance. The basic idea is that the Bluetooth signal from the Tile is received by the smartphone and based on the signal strength the iOS device will calculate the distance between the Tile and the iOS device which makes it possible to find the lost item or accessory. The Tile has built-in speaker which makes it another advantage to find the lost item.

           To use a Tile with a item, the Tile is first activated using any of the iOS device with the use of custom application ‘Tile App’. Then the Tile is kept along with the accessory we use. If we have lost that accessory, we will use the Tile application in the iOS device and activate an option that the Tile is lost. Now the Tile application with the help of Bluetooth will be able to detect the Tile if its in the range of 50ft to 150ft. If the Tile is not found in our place we can enable another option which makes other iOS devices(to whom you have shared) to send an update or notification to our iOS device if it detects our Tile in their range. Thus we will will be able to find the lost item anywhere and anytime.

Class Rating in Memory Cards – ALL YOU NEED TO KNOW

Class Rating in Memory Cards – ALL YOU NEED TO KNOW

          Memory cards are one of the most popular storage device which are used in portable electronic devices like smartphones, digital cameras, portable gaming consoles(PSP, Nvidia Shield etc), MP3 players etc. The revolution in science and technology has made made the memory card into very small chip with greater storage capacity ranging from megabytes to 256GB. Its a great thing that 256GB of data is accommodated into such a small chip. Also the price of the memory cards are getting cheaper and cheaper. Memory cards are available in different model(MMC, SD, microSD, SDXC, SDHC etc) which can be used based on the device compatibility or requirement.

          Transcend, Kingston, Sony etc are some of the popular memory card manufactures. It is quite normal that we always go for buying the products with less price and we expect a decent quality. This thought might lead to performance degradation in the electronic devices. Consider the below image.

8GB microSD memory card
1. Class 2
2. Class 4

          Both the 8GB memory cards in the above image are from same manufacturer, but the price in different. The memory card at the right side will be costlier than the memory card which at the left on the image. The difference lies in the Class Rating on it. Class Rating is a measure of read write performance of which is specified at the top right corner of the memory card with a number enclosed in a circle. The performance of any storage device can be measured by its read write performance. i.e the speed at which the data is transferred to and from the storage device. In the case of memory card Class Rating specifies its performance. The electronic device which we use may give low performance if we are using memory card with lesser Class Rating than the specified one. But in most cases we are considering only the storage with not being aware of the Class Rating. This will lead to performance degradation of the electronic device which we are using.

An example situation where we get degraded performance

          Consider we have digital camera which is capable of recording FullHD video which will be stored in the memory card. While shooting, the digital camera will shoot the video and the data will be continuously be transferred from camera to memory card. Consider we are using memory card with Class Rating 2 which will not be sufficient for recording FullHD video. This is because Class Rating 2 memory cards have read/write performance of upto 2MB/s. But the digital camera will be recording(generating the data) the video at 6MB/s or even 10MB/s. Thus the camera cannot record the video properly due to the low performance memory card. This is the case of any electronic device which uses memory  cards. So always go for memory cards with better class rating which is meant for the device we are using.Below table shows the Class Rating and its corresponding application use.

Class Rating and their Applications

MYO – YOUR MUSCLE CAN TALK – HAND BASED GESTURE CONTROL

MYO – YOUR MUSCLE CAN TALK – HAND BASED GESTURE CONTROL

            The technology we use has changed a lot. We control the technology with voice, hand gestures, eye and many more. Control of electronic devices like smartphones and televisions are controlled with voice with the use of latest technology in hardware and software. In advanced televisions and gaming consoles like Xbox, the system is able to track hand and other body movements. With such great innovation we have our next innovation in line up which is named MYO from Thalmic Labs,a wearable wrist  band which tracks the movement of hand and fingers.

For each movement in our body, there is a corresponding movement in our muscle. MYO which fits just above the wrist tracks the hand and finger movements by tracking the movement in the muscle and such muscle activity is converted into wireless signal which is sent to electrical devices like computer, laptop or a smartphone.

           MYO has the capability to control presentations, video, content, games, browse the web, create music, edit videos and many more. The developers from other field (like smartphone, gaming console) are coming forward to develop application which can be used with MYO. Currently the MYO is supported by Windows and Mac operating system and soon the APIs will be released for Android and iOS.

AMD Radeon RAMDisk – Software solution – Get faster performance than SSDs with existing RAM

AMD Radeon RAMDisk – Software solution – Get faster performance than SSDs with existing RAM

        We all know about computer storage devices namely volatile and nonvolatile storage. Non-volatile storage devices stores the data even during the device is powered off and on the other hand volatile storage devices do not store the data when it is powered off. Hard disks or hard drives used in desktops and laptops are best examples of non volatile storage devices. Solid-state disk(SSD) is another non volatile storage device which is newer technology and gaining popularity for its increased performance compared to the normal hard drive. The performance of the storage devices can be measured with read and write rates.i.e the speed at which the data are read and write from the storage device. Currently SSDs are commercial storage device which offers very great performance but with greater price tag. Random Access Memory(RAM) is the best example for volatile storage.

           The computers which we are using today comes with lot or RAM usually 8GB or 16GB and even 32GB or 64GB in high gaming systems and workstations. Are we using that full amount of memory? Actually the answer is NO except for the few cases like gaming and that too playing a high end game like Crysis (Crysis series) and Battlefield 3 will push the memory usage to the max of 8GB to 10GB. What happens to the rest of the memory(RAM). Of course it remains unused? This is the case even when we are doing daily computer activities like browsing the internet or when running graphic intensive applications like CAD or video editing or anything. Is there a better way to utilize the unused memory and that too with higher performance than SSD and hard disk? YESSSSSSSS!!!!

               Random Access Memory(RAM) are the fastest storage devices compared to SSD and hard disk.But RAM is volatile storage. AMD Radeon RAMDisk is a new and innovative software solution from AMD which enable the user to create virtual drive from the RAM(a part of the RAM can used to create virtual disk). We can run any application or game from the virtual drive created from Radeon RAMDisk which makes the applications or games run faster than when it run on hard disk or SSD. Virtual drive created from Radeon RAMDisk makes the user to store any data as if the data been stored in normal hard drive or SSD and can be accessed in similar way what we do in normal hard drives or SSDs.

So now we are using volatile storage as a non volatile storage with Radeon RAMDisk which increases the performance of the applications or games and we are able to utilize the full capability of the system without wasting the precious memory available in RAM.

           For an application or game to run, the required files will be transferred to and fro from the hard disk and RAM. In  Radeon RAMDisk the entire RAM is split into virtual drive(RAMDisk) and RAM. With Radeon RAMDisk, the entire content of the game or application will be create as virtual disk(virtual disk is the memory in RAM) and that virtual disk will act like a local hard drive. Now when we run the game or application from the virtual drive, the required data will need to be transferred to and fro from within the RAM i.e from the virtual disk and the RAM which makes the process faster than current generation SSD.

Features

  • Speed up internet page loads
  • Speed up disk to disk activities
  • Improved performance in gaming, video editing etc
Hard Drive SSD RAMDisk

 

From the above benchmark details from AMD, we can see a great performance improvement  in RAMDisk compared to the hard drive and SSD. The benchmarking tool used in Crystal Diskmark.

AMD Radeon RAMDisk is available for free with which you can create RAMDisk(virtual disk) upto 4GB. The commercial version of AMD Radeon RAMDisk costs $14.99 with which you can create RAMDisk upto 32GB and the Radeon RAMDisk with price tag $18.99 enable us to create RAMDisk upto 64GB. AMD Radeon RAMDisk can be used with memory modules from any manufacturer.
