One year in and bike sharing apps are transforming Chinese cities, but oversight and environmental impacts are a concern. Almost one hundred Chinese cities, from Beijing to Lhasa, now have bike-sharing schemes. The bikes, clad in various colours, have GPS trackers and can be unlocked simply by scanning a barcode on the frame with your phone. Some can even be reserved via a phone app. With bike sharing APP, cyclists will be able to reserve a bike from one of seven locations in person, via mobile app or online. The bikes can be used for recreation and convenient transportation. The seven docking stations are on a 3-mile loop and within or near popular downtown destinations.   According to a China Central Television report there are currently twenty bike-sharing schemes competing in Beijing, with almost one million bikes. Zhou Zhengyu, head of the city’s transportation commission, said at an event marking Beijing’s Bicycle Day in April that the city has 700,000 shared bikes. It is as

Over the past years, BSS(Bike Sharing Systems) have evolved from unsupervised to fully automated systems. In the beginnings, bike sharing suffered from anonymous use that led to theft. In recent years, the implementation of information systems in bike sharing overcame theft and enabled easy and quick access supporting rentals and returns at automated stations providing one-way trips. The implementation of BSS is rapidly growing. According to Midgley (2009), about 80 systems with almost 27,000 bikes and more than 4600 stations were in operation in May 2009. About 400 BSS have been introduced in Europe during the last 10 years. Markets in America and Asia are catching up.     In order to give more details on BSS, a brief overview of bike sharing evolution  is presented. Furthermore, the automated service process enabled by information  systems is discussed. Information systems also provide a vast amount of data  reflecting the mobility behavior in BSS. For a better understanding o

On any given day in Bangkok, Thailand, you can find more than 20,000 buses, minibuses, and vans operating on 470 routes. In a city of 8 million people with another 14 million in the greater Bangkok Metropolitan Region, public transportation is a necessity. Unfortunately, public transportation can also be a great liability.  GPS technology in public transport not only functions as a tracking device. It is also a form of deterrent to unsafe road practices. A bus driver will take more precaution and adopt road safety measures knowing that their vehicular usage is being constantly monitored.   Zero accident in public transportation can come to reality as in the beginning of 2016, Department of Land Transport has enforced all new-registered public transportation, trailers and lorries with 10 wheels or more to install  Vehicle GPS Tracking Device  . All data is linked to Department of Land Transport’s Transport Management Center to accommodate tracking and observe driving behavior. To f

Most companies have figured out that they need to remove the human factor from the equation as much as possible  The use of web-based monitoring and mobile communication is the impending wave of future products as most security providers are looking for better ways to protect or immobilize the truck and trailer without having to depend on the driver. Covert AGPS systems and mobile communication locking or controlling devices which can be monitored or applied remotely is where the security for the in-transit piece of the transportation industry is heading, especially for high value shipments  In the not too distant future, insurers are going to require this type of technology in return for affordable high value cargo shipment liability insurance coverage. Recently, at the company where I work, we were tracking some very high value shipments going from a Mexico origin to a Canadian destination for a large consumer product company. For this tracking application, we use an AGPS GSM track

Models specifically intended for mounted use in an automobile or on a boat will generally be too bulky and heavy to hold for extended periods. If ou want a GPS intended for handheld use in hiking and backpacking,  there are some great models that can work well for you. Qbit Mini  Personal GPS Tracker  was lighter and graphically displayed my path as I created it-both features I like. The newly-launched Qbit Personal GPS Tracker will give you a completely new level of awareness and convenience. It stands out by compact, lightweight design for both excellent mobility and reliability. Loaded with GPS, LBS and WIFI positioning, Qbit enables you to view real-time location from the computer, tablet or smart phone. It is capable of withstanding extreme environment. Being stylish, tough and accurate, Qbit is idea for kids, the elder and people with special needs. But there are prices to pay-in size, weight, and money-ifyou don't already have the computer. And you can practical

Linking Mini GPS Trackers, Maps, and Coordinate Systems Some people think that after they have a  GPS Tracking Device , they really don’t need a map, especially if the receiver has built-in mapping capabilities. This isn’t necessarily true. GPS receivers are best used in conjunction with maps, whether those maps are paper or digital. Here are some of the reasons why: Detail : Most maps on handheld GPS receivers don’t offer the detail of  full-size paper or digital maps, especially topographic maps and nautical  charts. Size : A GPS receiver’s screen is pretty darn small, and it’s just about  impossible to get the big picture that a full-size map can give you. Backup : If you have a paper map with you and know how to use it, the  map becomes an important backup if your GPS receiver’s batteries fail  or if you encounter poor satellite coverage. Gadget lovers might consider a paper map and magnetic compasses primitive, but they don’t  require batteries — and both are lightweight

Wireless IP Camera , Lens Most video-dome systems use high sensitivity color cameras that can be operated in: (1) color (2) monochrome (3) switch-over from color to monochrome automatically. The CCD cameras have an image format of 1/6 or 1/4 inch. These smaller sensor formats allow for a compact zoom lens and permit the small compact design that results in high pan/tilt speeds. Overall camera resolution is typically 480 TV lines for color and 570 TV lines for monochrome. Values of 1 lux sensitivity for color and 0.06 lux or less for monochrome are typical. Switchover from color to monochrome is automatic when the light level falls below a predetermined level. Cameras are also provided with DSP and automatic brightness control (ABC) so that the camera can view scenes containing both bright and dark areas. To capture image detail in both light and dark regions, Panasonic Inc. uses the Super Dynamic SDII technology, which records the scene at two different exposures and then electron

There are many video devices and features that can significantly enhance the effectiveness of a  Wireless Security Camera System . These include: electronic image-splitting and compression, data annotation, picture-in-a-picture, and video scan-reversal. An electronic image-splitting device is interposed in between the camera and the monitor, VCR, DVR, or video printer. It combines parts of the scenes of two or more cameras and displays them on one monitor. The use of the image splitter increases security in several ways. (1) decreases the number of monitors (2) permits the guard to view a monitor with two or three scenes on it rather than one (3) reduces the number of recorders  required by combining several scenes onto one video signal. Image splitters do not display the entire video scene from the cameras on the screen. They only display part of each camera scene: 1/2 of the scene if it is a 2-way split, 1/3 if 3-way split, and 1/4 if 4-way split.  It is often advantageous to di

Positioning with data link is not the same as referenced positioning (a method that allows measurements from more than one receiver to be combined and processed together in order to enhance accuracy), This external information includes measurements from other receivers, but it also includes other information which can be used to improve not only accuracy, but also other parameters in the specification, such as TTFF and sensitivity. It is very important for many applications to be able to provide instant positioning, i.e. to avoid the necessity of tracking a satellite signal and reading a navigation message. It takes up to 36 s to read a complete navigation message for a GPS L1 signal to ensure the decoding necessary for positioning data. If navigation message data are available through some other data link, it is still necessary to decode a time mark from the navigation message, which may require up to 6 s. BGPS (and AGPS before that) are very important for many applications because th

Indoor Housings Indoor housings must protect the  Home Security Cameras  and lens from pollutants such as dust and other particulate matter, a corrosive atmosphere, and tampering or vandalism. Indoor housings are constructed of painted or anodized aluminum, painted steel, stainless steel, and several types of plastic. The material for plastic housings must be flameproof or flame-retardant, as designated by local codes and UL recommendations. The housings must have sufficient strength to protect the lens and camera, and be sturdily mounted onto a fixed wall or ceiling mount, or recessed in a wall or ceiling. The lens should view through a clear window made of safety glass or plastic. Recommended plastic window material is either high impact acrylic or polycarbonate with a mar-resistant finish. The electrical input/output access locations should be designed and positioned for easy maintenance. For easy access and servicing of internal parts, the top half of the housing should be hin

Personal Tracking Device  is allowing elderly people and those with limited functionality to live independently longer, with caretakers doing their work remotely. General Electric, for example, has a product in which ubiquitous sensors can accurately and unobtrusively determine an independent elderly person’s activity. Currently, simple tracking systems are more common, such as a GPS-programmed “geofence” that sends an alert to a caretaker if the person has left a predefined area. The device is targeted to people who suffer from Alzheimer’s disease, although it can be used with children and teenagers as well. Lawmakers should be more aware of the possibility of caretakers abusing devices such as the i-TAG and the more sophisticated sensor systems. If an abused person leaves his or her home to escape, the caretaker would be notified instantly. And if gadgets or software monitor call logs as well, an abused person might have even more limited recourse. The abusive caretaker situatio

The joystick is moved forward or backward, left or right corresponding to the vertical (tilt) and horizontal (pan) movements of the camera/lens unit. Likewise, the thumb trackball is moved using the thumb to initiate pan and tilt. For the disk, touch-pad, and four-button design, left and right initiate panning, and top and bottom initiate tilt. The security officer watches the video monitor and can point the  Wireless Camera  to view any area within the pan/tilt rotation range. The platform and camera move in accordance with the control signal sent by the control unit. Pan/tilt platforms are available in a wide range of sizes from lightweight, pan-only units (scanners) for indoor applications to heavy-duty, environmentally protected pan/tilts for outdoor applications. Rugged outdoor units are environmentally enclosed and intended to withstand severe conditions of temperature, precipitation, dust, humidity, and high winds. In the late 1990s the requirement for faster, more compact,

I don’t know about you, but most people would jump at the chance to automate more things in their lives if doing so were affordable and could be achieved with reasonably minimal effort. Well, you’re in luck. Most of us are able to automate at least certain aspects of home life today because they don’t cost an arm or a leg, and they aren’t difficult to install. This blog focuses on how you can simply and relatively inexpensively control many of your daily tasks. Not only that, most of what I cover can be handled remotely, meaning you don’t even have to be at home to do this awesome stuff. Today, all you need to implement a home automation system is an Internet connection and (in some cases, but not all) a device to control it, such as a smartphone, table, or computer. Of course, you have to purchase a system or appliances, but many of them that utilize your Wi-Fi network (or even your home’s power lines) are inexpensive. Another bonus with today’s home automation technology is that yo
