Spy Video Car
The Spy Video Car is a hybrid product created by mixing a traditional RC car and a video baby monitor. The remote controller communicates digital command via the 49 MHz frequency to the car for control, and the camera on the car transmits video via the 2.4 GHz frequency to the remote controller for display. Because both directions use different radio frequency, they do not interfere with each other. The single-lensed display with a zoom lens produces a bigger virtual image in front of the operator, creating a first-person point of view feel for the driver. Wild Planet launched it for the 2006 Christmas season. It may be the first RC toy with built-in camera in the US market, and it also received the 2007 T.O.T.Y (Toy of The Year) award at the American International Toy Fair The North American International Toy Fair (formerly the American International Toy Fair and also known as Toy Fair New York) is an annual toy industry trade show held in mid-February in New Y ...

American International Toy Fair
The North American International Toy Fair (formerly the American International Toy Fair and also known as Toy Fair New York) is an annual toy industry trade show held in mid-February in New York City's Jacob K. Javits Convention Center and at toy showrooms around the city. The event is open to the toy trade only – toy industry professionals, retailers, and press representatives. It is produced by The Toy Association. Toy Fair New York's promoters describe it as the largest toy trade show in the Western hemisphere. History Toy Fair began in February 1903. The first event featured less than ten toy companies with Lionel trains among the featured products. As the event expanded, more space was needed which led to toy companies occupying 200 Fifth Avenue, a former hotel site, in 1910. By 1925, it was renamed the International Toy Center. The 117th annual Toy Fair, held February 22–25, 2020 at the Jacob K. Javits Convention Center, attracted tens of thousands of play innovato ...

Kopin Corporation
The Kopin Corporation () is a Westborough, Massachusetts-based electronics manufacturer, best known for its display devices for mobile electronics. Microdisplays President John C.C. Fan describes the company's growth strategy as being based on expanding the range of applications for microdisplays. Kopin has attempted to combat the trend of digital cameras being released without viewfinders through the development of tiny electronic displays, aimed at inclusion in higher-end cameras rather than budget models. Kopin's first CyberDisplay product debuted in 1999 in a JVC digital camera; it featured a 320x240 pixel display with a diagonal measurement. In 2007, the Olympus Corporation chose a Kopin CyberDisplay with QVGA-level resolution for inclusion as a viewfinder in its SP-550 UZ model. In 2012, the company's newest CyberDisplay model had a diagonal measurement of with VGA-level resolution of 640x480 pixels. Outside of the consumer market, Kopin's microdisplays have also been us ...

Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies; these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conductors can radiate into space as electromagnetic waves ( radio waves). This is the basis of radio technology. * RF current does not penetrate deeply into electrica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RC Car
'Radio-controlled cars'' (or RC cars for short) are miniature model cars, vans, buses, trucks or buggies that can be controlled from a distance using a specialized transmitter or remote. The term "RC" has been used to mean both "remote controlled" and "radio controlled"."remote controlled" includes vehicles that are controlled by radio waves, infrared waves or a physical wire connection, but the latter term is now obsolete. Common use of "RC" today usually refers only to vehicles controlled by radio, and this article focuses on radio-controlled vehicles only. Cars are powered by various sources. Electric models are powered by small but powerful electric motors and rechargeable nickel-cadmium, nickel metal hydride, or lithium polymer cells. There are also brushed or brushless electric motors - brushless motors are more powerful and efficient, but also much more expensive than brushed motors. Most fuel-powered models use glow plug engines, small internal combustion engines fuelle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virtual Image
In optics, an ''image'' is defined as the collection of focus points of light rays coming from an object. A '' real image'' is the collection of focus points made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. In other words, a virtual image is found by tracing real rays that emerge from an optical device (lens, mirror, or some combination) backward to perceived or apparent origins of ray divergences. In diagrams of optical systems, virtual rays are conventionally represented by dotted lines, to contrast with the solid lines of real rays. Because the rays never really converge, a virtual image cannot be projected onto a screen. In contrast, a real image can be projected on the screen as it is formed by rays that converge on a real location. A real image can be projected onto a diffusely reflecting screen so people can see the image (the image on the screen plays as an object to be imaged by human eyes). * A ...

Zoom Lens
A zoom lens is a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens (see prime lens). A true zoom lens, also called a parfocal lens, is one that maintains focus when its focal length changes. Most consumer zoom lenses do not maintain perfect focus, but are still parfocal designs. Most camera phones that are advertised as having optical zoom actually use a few cameras of different but fixed focal length, combined with digital zoom to make a hybrid system. The convenience of variable focal length comes at the cost of complexity – and some compromises on image quality, weight, dimensions, aperture, autofocus performance, and cost. For example, all zoom lenses suffer from at least slight, if not considerable, loss of image resolution at their maximum aperture, especially at the extremes of their focal length range. This effect is evident in the corners of the image, when display ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
