  • ZigBee is a specification for a suite of high level communication protocols using small, low- power digital radios based on an IEEE 802 standard for personal area networks. Applications include wireless light switches, electrical meters with in-home-displays, and other consumer and industrial equipment that require short-range wireless transfer of data at relatively low rates. The technology defined by the ZigBee specification is intended to be simpler and less expensive than other WPANs, such as Bluetooth. ZigBee is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, and secure networking. ZigBee has a defined rate of 250 kbps suited for periodic or intermittent data or a single signal transmission from a sensor or input device.
  • RF radio-frequency

  • ZED contains functionality to talk to the parent node (either the coordinator or a router). This relationship allows the node to be asleep a significant amount of the time thereby giving long battery life.
  • a ZED requires the least amount of memory, and therefore can be less expensive to manufacture than a ZR or ZC.
  • the protocols build on recent algorithmic research (Ad-hoc On-demand Distance Vector, neuRFon) to automatically construct a low-speed ad-hoc network of nodes. In most large network instances, the network will be a cluster of clusters. It can also form a mesh or a single cluster.
  • the current ZigBee protocols support beacon and non-beacon enabled networks. In non-beacon-enabled networks, an unslotted CSMA/CA channel access mechanism is used. In this type of network, ZigBee Routers typically have their receivers continuously active, requiring a more robust power supply. However, this allows for heterogeneous networks in which some devices receive continuously, while others only transmit when an external stimulus is detected.
  • beacon-enabled networks the special network nodes called ZigBee Routers transmit periodic beacons to confirm their presence to other network nodes. Nodes may sleep between the beacons, thus lowering their duty cycle and extending their battery life. Beacon intervals depend on the data rate; they may range from 15.36 milliseconds to 251.65824 seconds at 250 Kbit/s, from 24 milliseconds to 393.216 seconds at 40 Kbit/s and from 48 milliseconds to 786;432 seconds at 20 Kbit/s. In general, the ZigBee protocols minimize the time the radio is on, so as to reduce power use. In beaconing networks, nodes only need to be active while a beacon is being transmitted. In non- beacon-enabled networks, power consumption is decidedly asymmetrical: some devices are always active, while others spend most of their time sleeping.

  • Z-Wave uses a source-routed mesh network topology and has one or more master controllers that control routing and security.
  • the devices can communicate to another by using intermediate nodes to actively route around and circumvent household obstacles or radio dead spots that might occur.
  • a message from node A to node C can be successfully delivered even if the two nodes are not within range, providing that a third node B can communicate with nodes A and C. If the preferred route is unavailable, the message originator will attempt other routes until a path is found to the "C" node. Therefore a Z-Wave network can span much farther than the radio range of a single unit; however with several of these hops a delay may be introduced between the control command and the desired result.

  • People counting is a tool commonly used as part of the BA in the retail environment, where a device is used to measure the number and direction of people traversing a certain passage or entrance per unit time. The resolution of the measurement is entirely dependent on the sophistication of the technology employed. The device is often used at the entrance of a building so that the total number of visitors can be recorded. Many different technologies are used in people counter devices, such as infrared beams, computer vision, thermal imaging and pressure- sensitive mats. There are various reasons for counting people in a retail environment. In retail stores, counting is done as a form of intelligence-gathering. The use of people counting systems in the retail environment is necessary to calculate the conversion rate, i.e., the percentage of a store's visitors that makes purchases.
  • the basic people counting device is a Tally Counter, a hand-held device (a.k.a. clicker- counter), having a counter based on one press per person.
  • Another simple people counter type is based on infrared beams, where the horizontal infrared beam is formed across an entrance which is typically linked to a small display unit at the side of the doorway or can also be linked to a PC or send data via wireless links and GPRS.
  • Such a beam counts a 'tick' when the beam is broken, therefore it is normal to divide the 'ticks' by two to get visitor numbers.
  • Dual beam units are also available from some suppliers and can provide low cost directional flow 'in' and Out' data. Accuracy depends highly on the width of the entrance monitored and the volume of traffic.
  • People counting technique may be based computer vision systems.
  • Computer vision systems typically use either a Closed-Circuit Television (CCTV) camera or IP camera to feed a signal into a computer or embedded device.
  • Some computer vision systems have been embedded directly into standard IP network cameras. This allows for distributed, cost efficient and highly scalable systems where all image processing is done on the camera using the standard built in CPU. This also dramatically reduces bandwidth requirements as only the counting data have to be sent over the Ethernet.
  • Accuracy varies between systems and installations as background information needs to be digitally removed from the scene in order to recognize, track and count people. This means that CCTV based counters can be vulnerable to light level changes and shadows, which can lead to inaccurate counting. Lately, robust and adaptive algorithms have been developed that can compensate for this behavior and excellent counting accuracy can today be obtained for both outdoor and indoor counting using computer vision.
  • Thermal imaging systems for people counting are using array sensors which detect heat sources, rather than using cameras as in computer vision systems. These systems are typically implemented using embedded technology and are mounted overhead for high accuracy. Since thermal imaging systems detect the heat emitted by people, they can be susceptible to external weather conditions that reduce the amount of heat emitted from a person walking in from an outdoor environment.
  • 3D imaging Another people technology uses 3D imaging.
  • Various technologies exist for acquiring a 3D image of the scene such as 2 video cameras in order to reproduce the human 3D vision (also known as stereo-vision), and Time-of-Flight (TOF) sensors use pulsed or modulated emitted IR light to acquire the 3D image of the scene.
  • TOF sensors use pulsed or modulated emitted IR light to acquire the 3D image of the scene.
  • structured light sensors may be used to acquire the 3D image of the scene using projected light pattern.
  • a BI system may typically generate two types of BI insights.
  • a first type of BI insights is a statistical insight based on long-term data, for example, product sale during an entire month or year.
  • the BI server may operate efficiently as more processing may be required and real-time results are not important.
  • a second type of BI insights is an insight based on short-term data or temporal data, or data which is time-sensitive, or BI insights which are relevant or useful only for a short time-frame or only for immediate attention, for example, detection of a long queue of customers at a cash register or a PoS terminal.

  • Multiple distinct or independent communication routes provide higher reliability such as avoiding single point of failure (SPOF), where in the case of any failure in one of the communication routes, the other routes may still provide the required connection and the system functionality is preserved, thus a therein renders the system fully functional, using a backup or failsafe scheme.
  • the operation of the redundant communication routes may be based on standby redundancy, (a.k.a. Backup Redundancy), where one of the data paths or the associated hardware is considered as a primary unit, and the other data path (or the associated hardware) is considered as the secondary unit, serving as back up to the primary unit.
  • the secondary unit typically does not monitor the system, but is there just as a spare.
  • the standby unit is not usually kept in sync with the primary unit, so it must reconcile its input and output signals on the takeover of the communication.
  • This approach does lend itself to give a "bump" on transfer, meaning the secondary operation may not be in sync with the last system state of the primary unit.
  • Such mechanism may require a watchdog, which monitors the system to decide when a switchover condition is met, and command the system to switch control to the standby unit.
  • Standby redundancy configurations commonly employ two basic types, namely 'Cold Standby' and 'Hot Standby'.
  • the secondary unit In cold standby, the secondary unit is either powered off or otherwise non-active in the system operation, thus preserving the reliability of the unit.
  • the drawback of this design is that the downtime is greater than in hot standby, because the standby unit needs to be powered up or activated, and brought online into a known state.
  • the secondary unit On hot standby, the secondary unit is powered up or otherwise kept operational, and can optionally monitor the system.
  • the secondary unit may serve as the watchdog and/or voter to decide when to switch over, thus eliminating the need for an additional hardware for this job.
  • This design does not preserve the reliability of the standby unit as well as the cold standby design. However, it shortens the downtime, which in turn increases the availability of the system.
  • Some flavors of Hot Standby are similar to Dual Modular Redundancy (DMR) or Parallel Redundancy. The main difference between Hot Standby and DMR is how tightly the primary and the secondary are synchronized. DMR completely synchronizes the primary and secondary units.
  • TSP Modular Redundancy (a.k.a. Parallel Redundancy) refers to the approach of having multiply units or data paths running in parallel. All units are highly synchronized and receive the same input information at the same time. Their output values are then compared and a voter decides which output values should be used.
  • This model easily provides 'bumpless' switchovers. This model typically has faster switchover times than Hot Standby models, thus the system availability is very high, but because all the units are powered up and actively engaged with the system operation, the system is at more risk of encountering a common mode failure across all the units.
  • Quadruple Modular Redundancy is fundamentally similar to TMR but using four units instead of three to increase the reliability. The obvious drawback is the 4X increase in system cost.
  • Dual Modular Redundancy uses two functional equivalent units, thus either can control or support the system operation.
  • the most challenging aspect of DMR is determining when to switch over to the secondary unit. Because both units are monitoring the application, a mechanism is needed to decide what to do if they disagree. Either a tiebreaker vote or simply the secondary unit may be designated as the default winner, assuming it is more trustworthy than the primary unit.
  • Triple Modular Redundancy uses three functionally equivalent units to provide a redundant backup. This approach is very common in aerospace applications where the cost of failure is extremely high. TMR is more reliable than DMR due to two main aspects. The most obvious reason is that two "standby" units are used instead of just one. The other reason is that in a technique called diversity platforms or diversity programming may be applied.
