ABSTRACT:
TECHNICAL FIELD
The present invention relates to network interface cards. In particular, the present invention pertains to a device that provides an antenna for wireless transmission on a peripheral component (e.g., a type II PCMCIA card), along with a receptacle (e.g., an X-Jack™) and a wireline connector (e.g., a 15-pin connector).
BACKGROUND ART
Computers have become an integral tool used in a wide variety of different applications, such as in finance and commercial transactions, computer-aided design and manufacturing, health care, telecommunication, education, etc. Computers are finding new applications as a result of advances in hardware technology and rapid development in software technology. Furthermore, a computer system's functionality is dramatically enhanced by connecting it to a network, another computer, or a device such as a FAX machine. This allows the computer to exchange files; share information stored on a common database; connect to the Internet; and communicate via FAXes, e-mail, and teleconferencing.
In some instances, in order make such connections, a peripheral component generally known as a network interface card (NIC) must be inserted into the general purpose computer. The NIC may provide multiple ways to make such connections. For example, the NIC may have a receptacle for plugging in a jack which interfaces with a modem, LAN, or ISDN. Alternatively, a wireline connector on the NIC may allow a connection via a parallel cable, a serial cable, a SCSI cable, etc. to another device. Essentially, the peripheral component works with the operating system and central processing unit (CPU) of the host computer to control the flow of information over the various types of connections.
In addition to the two type of connections listed above, it is becoming increasingly desirable to provide a wireless connection to a peripheral component. Unfortunately, peripheral components, such as PCMCIA cards have very limited space. Wireless interfaces, such as antennas, have been added to some conventional peripheral components, but at the expense of removing either the receptacle or the wireline connector (e.g., a 15-pin connector.
Other conventional solutions have modified the 15-pin connector, for example, providing for fewer pins. Unfortunately, this may make the connector incompatible with some technologies.
Another conventional technique used to add a wireless interface to a peripheral component is to move the location of the receptacle. For practical reasons, all of the interfaces must be at one end of the peripheral component. One conventional solution moves the receptacle from the left edge of the interface end to the middle of the interface end. However, this may interfere with the circuitry inside the peripheral component, a component with very limited internal space.
The above problems are exceptionally difficult to deal with when the peripheral component is a type II PCMCIA card, as the size and shape of the card is both limited and fixed by standards.
Accordingly, a need exists for a peripheral component which has multiple types of interfaces. In particular, a need exists for a peripheral component with a receptacle interface, a wireline connector interface, and a wireless interface. A further need exists wherein such a peripheral component is a type II PCMCIA card. A further need exists for such an apparatus which interferes minimally with the circuitry inside of the peripheral component.
DISCLOSURE OF THE INVENTION
The present invention provides a peripheral component providing multiple types of interfaces. Embodiments of the present invention provide for a peripheral component with a receptacle interface, a wireline interface, and a wireless interface. Embodiments provide for a such a peripheral component being a type II PCMCIA card. Embodiments provide for such as device which interferes minimally with the logical circuitry inside the peripheral component.
A peripheral component providing multiple types of interfaces is disclosed. In one embodiment, the peripheral component comprises a housing with logical circuitry within. A receptacle is electrically connected to the logical circuitry. The receptacle may be operable to receive an RJ-11 plug and/or an RJ-45 plug. A wireline interface, for example, a 15-pin connector, is also electrically connected to the logical circuitry. Furthermore, a resilient antenna is electrically connected to the logical circuitry. The antenna is operable to conform to fit inside the housing, and when extracted, the antenna is operable to return substantially to a predetermined shape, wherein reception and transmission of a wireless signal are optimized.
In another embodiment, the receptacle is within a platform having a groove into which the antenna slideably fits. In one embodiment, the receptacle platform slideably extracts from and inserts into the housing, along with the antenna.
In one embodiment, the logical circuitry of the peripheral component comprises a wireless device, for example, a Bluetooth™ device.
In another embodiment, the peripheral component is a type II PCMCIA card. In still another embodiment, the receptacle is an X-Jack™. In still another embodiment, the wireline interface is adapted to receive a 15-pin connector.
These and other objects and advantages of the present invention will become obvious to those of ordinary skill in the art after having read the following detailed description of the preferred embodiments which are illustrated in the various drawing figures.
