Patent Application
20120169480
The present application relates generally to wireless communication and information storing.
Modern society has adopted, and is becoming reliant upon, electronic devices for various purposes, such as, storing information. Electronic devices can vary from battery powered handheld devices to stationary household and/or commercial devices utilizing an electrical network as a power source. Due to rapid development of the electronic devices a number of areas capable of enabling entirely new types of practical applications have emerged. Not only has the processing power of electronic devices become faster and more power efficient than before, but also the memories and radio communication interfaces have developed with leaps such that new opportunities for useful implementations arise with an increasing pace.
Radio Frequency Identification (RFID) is an example of a technology that is experiencing a change of generation thanks to development in both communications and memory technologies. Originally, RFID was intended to provide an inexpensive, remotely readable tag that basically functions as a remotely readable bar code with a small memory to hold for example the identity of the tag. The tag comprised a small persistent memory with a unique identity (ID) corresponding to a code represented by the bar code system. For remote reading, a wireless transponder was provided to send the ID when receiving suitable radio transmission powering the transponder. Recently, faster radio powered communication technologies have been developed and the development of new memories enable storing of more than just some bytes of data in a memory associated with an RFID tag.
The Micro-Nano integrated platform for transverse Ambient Intelligence applications, (MINAmI) Project, Supported by the European Commission through the Sixth Framework Programme for Research and Development, addresses Ambient Intelligence (AmI) applications, where an electronic device, such as a personal mobile device may act as a gateway. With the MINAmI Ambient Intelligence system, the physical environment can be loaded with interesting and context related information, easily and naturally accessible to the user. Information may be stored in radio frequency tags and sensors embedded in physical surroundings and everyday objects, and it can be anything from sensor measurements from the environment to a piece of music or the latest news. The user of the personal mobile device can wirelessly access this information content by just touching or scanning close to the radio frequency tags and/or sensors with the personal mobile device capable of machine reading the information content. The personal mobile device, such as a mobile phone may also enable wireless connection to the internet. As the interaction can be tied to a specific place, object, and time, the user may be served with context related information and services. The MINAmI Project is intended to define a communication protocol/system for providing high data rate communication between a reader/writer device and large memory containing radio frequency tags operating over a high data rate communication channel.

According to a further example embodiment, apparatus 200 may be a stationary device having a wireless and/or a wired interface for communicating with network 120.
As further shown in
According to one example embodiment of the present invention, the apparatus 200, such as a portable reader/writer device, may transmit RF power to the write-enabled radio frequency tag device 300 for providing the necessary power for the write-enabled radio frequency tag device 300 to operate and/or communicate. The apparatus 200 may include an ultra-high frequency (UHF) power transceiver configured to transmit RF power to the write-enabled radio frequency tag device 300. Alternatively, necessary RF power for tag operation may be included in interrogation signals transmitted by the apparatus 200 for detecting radio frequency enabled devices as shown in the example embodiment of
Apparatus 200 may use the received response signal for detecting presence of the write-enabled radio frequency tag device 300. After detection of the write-enabled radio frequency tag device 300 by the apparatus 200 embodied for example as a reader/writer device in accordance with
The write-enabled radio frequency tag device 300, after receiving the data transmitted by the apparatus 200, may store the data to an associated memory 350 in accordance with the operation mode indication provided by the apparatus 200.
Control module 210 is configured to regulate operation of the apparatus 200. The control module may be embodied as a controlling means, for example as a controlling circuitry or a processor. Inputs for the control module 210 may be received from various other modules comprised within apparatus 200. For example, user interface 260 may provide input to the control module 210 in response to receiving input from a user via user input 262. So, user input received via the user interface 260 may be used as an input in the control module 210 for controlling the operation of the apparatus 200. Control module 210 may interpret and/or process the input data and, in response, may issue one or more control commands to at least one of the other modules in apparatus 200.
In accordance with an example embodiment, apparatus 200, such as an electronic device, comprises communications interfaces 220. Communications interfaces 220 may incorporate one or more communication modules of the apparatus 200. In an example embodiment, the communications interfaces 220 may comprise means for wired and/or wireless communication. As shown in the example of
Short-range communication module 230 may comprise a radio-frequency identification (RFID) module embodied as RFID reader/writer. RFID technologies comprise a range of RF transmission systems, for example standardized and proprietary systems for a large number of different purposes, such as product tagging for inventory handling and logistics, theft prevention purposes at the point of sales and product recycling at the end of the life-cycle of the tagged product. In addition, RFID systems have been introduced for various payment and ticketing concepts comprising public transportation ticketing and payment. As an example, in several European countries and also in Canada and Mexico, there are several public transportation systems based on Calypso, the international electronic ticketing standard for microprocessor contactless smartcards, originally designed by a group of European transit operators. Further, for example in Japan, Hong Kong and Korea, there are Felicity Card (FeliCa) technology based mass transit systems, such as the Octopus card system in Hong Kong. The Octopus card is a rechargeable contactless stored value smart card used to transfer electronic payments in online or offline systems in Hong Kong.
As a subset of RFID technologies, Near Field Communication (NFC) technology that has evolved from a combination of existing contactless identification and interconnection technologies. NFC is both a “read” and “write” technology. Communication between two NFC-compatible devices occurs when they are brought within close proximity of each other: a simple wave or touch can establish an NFC connection, which is then compatible with other known wireless technologies, such as Bluetooth™ or wireless local area network (WLAN). NFC can be used with a variety of devices, from mobile phones that enable payment or transfer information to digital cameras that send their photos to a TV set with just a touch to name a few examples.
As the RFID technologies are becoming more prevalent, there already exists a large amount of RFID based applications, for example transportation tickets, animal and/or human implantations for tracking and other purposes, and the like. Radio-Frequency Identification (RFID) technologies provide wireless systems for automatic identification, tracking and managing of objects via a wireless connection between a tag attached to the object and a reader device, such as apparatus 200. The tag, such as write-enabled radio frequency tag of
Short-range communication module 230 may also comprise short-range communication interface embodied for example as a transmitter and/or receiver for exchanging information across short-range wireless network using a short-range communication protocol.

Examples of wireless long-range communication technologies comprise 2nd generation (2G) digital cellular networks, for example Global System for Mobile Communications (GSM) that may communicate in the 900 MHz/1.8 GHz bands in Europe and in the 850 MHz and 1.9 GHz bands in the United States. Long-range communication technologies may further comprise general packet radio service (GPRS) technology, universal mobile telecommunications system (UMTS) technology, code division multiple access (CDMA) technologies, and/or the like. Long-range communication technologies may also operate to transmit and receive messages, such as text messages via a short messaging service (SMS), and/or multimedia content via multimedia messaging service (MMS) messages. Long-range communication technologies may provide voice and data services.
As a subset of long-range communications module 240, or alternatively operating as an independent module separately coupled to processor 210, the apparatus 200 may comprise a broadcast receiver. The broadcast receiver may be a digital audio- or video receiver, for example a digital audio broadcasting (DAB) or a digital video broadcasting (DVB) receiver, and/or the like. According to an example embodiment, the broadcast receiver comprises a Digital Video Broadcast for Handheld Apparatuses (DVB-H) receiver. The broadcasting transmissions may be encoded so that only certain apparatuses may access the transmitted content. The broadcast transmission may comprise text, audio and/or video information, and data. In an example embodiment, apparatus 200 may receive broadcasts and/or information within the broadcast signal to determine if the apparatus is permitted to view the received content.
According to one example embodiment either the short-range communications module 230, or the long-range communications module 240 may be equipped with a wired interface that may be used for communicating with another device using a wired communication protocol via an interface such as Ethernet, an IEEE 1394 communication interface, a universal serial bus (USB) interface, and/or the like.
According to one embodiment, apparatus 200 may further comprise an RF powering interface 250. RF powering interface 250 may be configured to provide a wireless signal for enabling a write-enabled device, such as the write-enabled radio frequency tag device 300 of
User interface 260 may include visual, audible and/or tactile elements which allow a user to receive data from, and enter data into, the apparatus. Data entered by a user is received via user input module 262 and may be interpreted by control module 210, for example to affect the behavior of apparatus 200. User-inputted data may also be transmitted via any of the communication modules of the communications interfaces 220 to another device. Information may also be received by other devices at the apparatus 200 via communications interfaces 220. Control module 210 may cause this information to be transferred to user interface 260 for presentation to the user via user output module 264. User interface 220 may comprise one or more user input and output modules, and there may also be a module operating both as a user input module 262 and user output module 264, for example a touch screen display operating as a tactile user interface.
Apparatus 200 may further comprise a memory and/or storage 270. Memory/storage 270 may be connected to controller 210. Memory/storage 270 may include an application module 275. The application module 275 may comprise other hardware and/or software applications of apparatus 200. The memory/storage 270 may also incorporate a database 280. The database 280 may comprise one or more data items, for example information related to one or more users of the apparatus 200. The data items may be related to identification information. Memory/storage 270 may further store executable instructions that are configured to cause the apparatus 200 to perform various actions in co-operation with the control module 210.
Antenna modulator 320 controls one or more properties of antenna 315, such as its impedance. This enables the tag device 300 to reflect and/or absorb reader-initiated transmissions. Such reflections or absorptions may be used to convey information in response to interrogation signals. Antenna modulator 320 may cause such reflections and/or absorptions to occur in response to particular portions of interrogation signals, such as clock pulses.
Power module 360, which may also be included in the RF interface 310, provides power to tag components. For instance, power module 360 may include electronics (such as coil(s), rectifier(s), and/or capacitor(s)) to harvest energy from received electromagnetic transmissions, such as from an interrogation signal composed of a series of pulses. In addition to conveying information, each of these pulses may transfers energy that keeps voltage of the tag device 300 above the tag's minimum required operational voltage. Therefore, the tag device 300 may continually operate without any internal power source until the voltage decays below the minimum required operational voltage.
According to an alternative embodiment, the power module 360 may receive power from transmissions originated by another transmission source. So, instead of receiving operational power through received interrogation signal, the tag device 300 may receive power from an RF powering signal provided for example by RF powering interface 250 of apparatus 200.
According to a further alternative embodiment, the power module 360 may include an internal power source, such as a battery so that the tag device 300 can remain operational (i.e. perform various internal processes such as storing data etc.) without external powering. However, even with internal power source the tag device 300 may still require the external RF field for communication with external devices.
A clock extraction module 330 provides timing information. According to an embodiment the clock extraction module is configured to govern performance of other tag components. For instance, the clock extraction module 330 may control the timing in which antenna modulator 320 varies the impedance of antenna 315. According to an embodiment the clock extraction module 330 is configured to provide time stamps, e.g. to any received or transmitted packets or signals.
Processing module 340 controls device operation. As shown in
Memory/storage 350 stores information in the form of data and software components (also referred to herein as modules). This data includes information for transmission to readers, such as a tag identification information and tag data. These software components include instructions that can be executed by processing module 340. Various types of software components may be stored in memory/storage 350. For instance, memory/storage 350 may store software components that control the generation of tag data. Memory/storage 350 may be implemented with random access memory (RAM), read only memory (ROM), Flash memory and/or phase change memory (PCM), or like.
According to an example embodiment of
According to one embodiment, the memory/storage 350 may comprise either separated or predefined memory sections for SLC and MLC memories so that a portion of the memory/storage is fixed for specific data storing. Alternatively, the memory/storage 350 may comprise a memory that can be dynamically allocated to SLC and MLC based on the current needs for storing data.
When considering various write-enabled devices, such as the write-enabled radio frequency tag device 300 of
However, when communicating with passive devices, a reader/writer device, such as apparatus 200, have to provide necessary power for the passive device, such as the write-enabled radio frequency tag device 300 to operate and communicate with the reader/writer device. So, the power consumption of the passive device may result as increased power consumption of the reader/writer device. In a battery powered device, such as apparatus 200, energy consumption is an important topic to consider in connection with operating times, which depends on the current required for operating the device and available battery capacity. So, the higher the energy consumption of apparatus 200 is, the smaller the battery lifetime is for the same device. SLC memory has the advantage of lower power consumption and faster speed in write operation over MLC memory. So, from energy consumption point of view SLC memory may be preferred for writing data to a device, such as the write-enabled radio frequency tag device 300, over MLC.
In view of the above discussion, when writing data to a memory associated with a passive write-enabled device, such as the write-enabled radio frequency tag device 300, there are tradeoffs that need to be considered in terms of storage density and power consumption especially from the perspective of user experience of a reader/writer apparatus, such as apparatus 200. As an example, when a device writing data for example to the memory/storage 350 of the write-enabled radio frequency tag device 300, belongs to a party hosting the write-enabled radio frequency tag device 300 (i.e. a party providing the write-enabled radio frequency tag device 300 and/or responsible for maintaining general content on the write-enabled radio frequency tag device 300) one important characteristic may relate to the available memory size. On the other hand, when a device writing data for example into the memory/storage 350 of the write-enabled radio frequency tag device 300, belongs to a party that is not hosting the write-enabled radio frequency tag device 300 (i.e. any other device by-passing the write-enabled radio frequency tag device 300 with a need to write data into the memory/storage 350 of the write-enabled radio frequency tag device 300) one important characteristic may relate to the required energy consumption and/or to speed of the write operation.
According to an embodiment of the present invention, to provide means for enhanced user experience in connection with data storing into write-enabled devices, such as the write-enabled radio frequency tag device 300, at least two different operation modes for write operation are provided.
A host operation mode comprising a protocol configured to write data to a write-enabled device, such as the write-enabled radio frequency tag device 300, may be selected for example to ensure optimal storage density at the write-enabled radio frequency tag device 300 by instructing the write-enabled radio frequency tag device 300 to store received data e.g. into a memory section #2354 dedicated for storing two or more bits of data in each memory cell comprising a multi-level cell (MLC) memory. According to one embodiment, when a reader/writer device, such as apparatus 200 transmits data to a write-enabled passive device for writing according to the host operation mode, the transmitted data is associated with an indication associated with the host operation mode. According to one embodiment, the host mode operation indication may be added to the data by a dedicated inserter module operating for example under control, or in connection with control module 210 of the reader/writer apparatus 200. Upon receiving the data including the host operation mode indication, the passive write-enabled device, such as the write-enabled radio frequency tag device 300, is aware that the received data is to be stored into a memory section dedicated for MLC, such as the memory section #2354 of
A visitor operation mode comprising a protocol configured to write data to a write-enabled device, such as the write-enabled radio frequency tag device 300, may be selected for example to ensure optimal write speed and/or power consumption for the reader/writer device, such as the apparatus 200, when writing data into the write-enabled radio frequency tag device 300. Data to be written into the write-enabled radio frequency tag device 300 may be associated with an indication for the write-enabled radio frequency tag device 300 to store received data e.g. into a memory section #1352 dedicated for storing one data bit in each memory cell comprising a single-level cell (SLC) memory. According to one embodiment, when a reader/writer device, such as apparatus 200 transmits data to a write-enabled device for writing according to the visitor operation mode, the transmitted data is associated with an indication associated with the visitor operation mode. According to one embodiment, the visitor operation mode indication may be added to the data by a dedicated inserter module operating for example under control, or in connection with control module 210 of the reader/writer apparatus 200. Upon receiving the data including the visitor operation mode indication, the passive write-enabled device, such as the write-enabled radio frequency tag device 300, is aware that the received data is to be stored into a memory section dedicated for SLC, such as the memory section #1352 of
It should be noted that there might be also other operation modes in addition or instead of the host and visitor operation modes. Only data associated with the host operation is stored into a memory section dedicated for MLC according to one embodiment of the present invention.
Further, according to one embodiment of the present invention, if received data includes no indication of the operation mode, a passive write enabled device, such as the write-enabled radio frequency tag device 300 considers the operation mode as a non-host operation mode and stores the received data into a memory section dedicated for SLC according to the visitor operation mode.
Although
In response to the transmitted signals, the apparatus may receive one or more wireless signals that can be used for detecting external devices, as shown in block 420. In case no write-enabled tag devices are detected, the method goes directly back to block 410 and continues with searching for radio frequency devices. According to one embodiment, the operation may be periodical so that a predetermined delay is implemented before entering back to block 410. In case at least one detected device comprises a write-enabled tag, the method may continue with block 430 that can be considered as optional block according to some embodiments of the present invention. In block 430 the apparatus negotiates with the detected write-enabled tag device an operation mode to write data to a memory associated with the write-enabled tag device. The negotiation of the operation mode for write operation may comprise exchanging one or more signals with the tag. The operation mode to write data to the memory associated with the write-enabled tag device is selected in block 440. According to one embodiment the operation mode comprises a protocol for writing data to the write-enabled tag device, wherein the protocol may comprise exchange of one or more signals including data and an operation mode indication associated with the data. According to one embodiment, the method 400 proceeds straight from block 420 to 440.
After selection of the operation mode to write data to the memory associated with the write-enabled tag device in block 440, the method continues with block 450 where the apparatus is configured to perform the write operation according to the selected operation mode. According to an embodiment, the write operation mode comprises communicating with the write-enabled tag device according to the protocol for writing data to the write-enabled tag device, wherein the protocol may comprise exchange of one or more signals including data and an operation mode indication associated with the data. According to an embodiment of the present invention, selectable operation modes comprise at least a host mode and a visitor mode. Irrespective of the operation mode to write data to the memory associated with the write-enabled radio frequency tag, the write operation comprises transmitting the specific data to the write-enabled tag device with an indication associated with the selected operation mode. Upon receiving the transmitted data and the indication associated with the selected operation mode, the write-enabled tag device may store the received data to an associated memory of the write-enabled tag device according to the selected operation mode.
The method 400 continues with optional decision block of 460, where the selected operation mode is checked, and in case the selected operation mode comprises the host operation mode, the method may continue with optional decision block 470. If the selected operation mode does not comprise host mode, the method goes back to block 410 and continues with searching for radio frequency devices. In the optional decision block 470, the apparatus, such as the reader/writer device 200 of
The method 500 continues with decision block 540, where it is determined whether the received indication corresponds with a host operation mode. According to one embodiment, if the indication corresponds with host operation mode, the received payload data is stored in a memory section of an associated memory suitable for storing at least two bits of data in each memory cell of the associated memory as shown in block. In case the indication does not correspond to the host operation mode, such as visitor operation mode, the received payload data is stored in a memory section of an associated memory suitable for storing one data bit in each memory cell of the associated memory as shown in block 560. According to one embodiment, if no operation mode indication is received, the received payload data is stored in a memory section of an associated memory suitable for storing one data bit in each memory cell of the associated memory as shown in block 560. According to one embodiment of the present invention, both of the memory sections are suitable for storing at least two bits of data in each memory cell of the associated memory and the relative proportions of the memory sections are adjustable according to current need.
According to an embodiment of the present invention, a write-enabled tag device, such as the write-enabled radio frequency tag device 300, may negotiate with a reader/writer apparatus after the initial data writing operation whether the reader/writer apparatus, such as the apparatus 200, is co-operative to participate in writing at least a portion of the data sectors within a memory associated with the write-enabled tag device in a compressed manner according to host operation mode where two or more bits of data is stored in each memory cell of the memory associated with the write-enabled tag device. If the negotiation results in compression operation, the write-enabled tag device may store the corresponding data sectors within the associated memory according to the host operation mode.
