1. Field
Embodiments of the invention relate generally to the field of flash media adapters, and more specifically to a device and method for reducing the manufacturing costs thereof.
2. Background
Adapters, such as those as described in co-pending U.S. application Ser. No. 10/064,966, which was filed on Sep. 4, 2002, entitled “SmartConnect Universal Flash Media Card Adapters” are capable of interfacing one or more different types of flash media cards to another flash media receptacle, such as a CompactFlash or PCMCIA slot in a host processing system. This allows other media to be interfaced and serviced as well. Such other media could include a new P-Tag (Personal Tag for Military Use) device known to the inventor, SmartMedia(tm) (“SM”), Memory Stick(tm) by Sony (“MS”), Secure Digital(tm) (“SD”), and MultiMediaCard™ (“MMC”), or any other media having a form factor capable of fitting within an adapter housing built to the receptacle mechanical specifications such as the Memory Stick Duo from Sony or XD Picture Card from Fuji, Olympus and Toshiba.
The problem is that each adapter type requires a separate frame kit. Although the number of frame kits can be reduced for multi-port adapters if on their port side the port opening is done in accordance with the disclosure of the above-referenced co-pending application. The host processing system interface may be one of at least two different formats, namely a CompactFlash card (CF card), or a Personal Computer Memory Card International Association (PCMCIA card).
A major drawback of having different frame configurations for each type of host processing system interface is in the area of manufacturing and tooling. In general, tooling costs depend on the non-recurring engineering (NRE) costs and the lifetime of the tool (number of times it can be pressed before replacement is necessary). For the manufacturing of flash memory media adapters, such tooling costs may be significant. For example, at manufacturing, switching production from one type of frame (e.g., PCMCIA card) to another (e.g., CF card) may occur as frequently as every day or two, at which point “NRE cost” becomes somewhat of a misnomer.
An additional drawback of current flash memory adapters is that they do not provide a mechanism for easily determining an insertion problem such as pin-contact failure or improper insertion of the flash memory medium (e.g., upside down).
An embodiment of the invention provides a connector interface frame comprising a plurality of detachable limbs. When one or more specified limbs are detached, the connector interface frame accommodates a particular one of a plurality of host processing system connector interfaces.
Other features and advantages of embodiments of the present invention will be apparent from the accompanying drawings, and from the detailed description, that follows below.
The invention may be best understood by referring to the following description and accompanying drawings that are used to illustrate embodiments of the invention. In the drawings:
An embodiment of the invention provides a frame for a host processing system connector interface. The frame has a number of detachable limbs configured so that depending on which limbs are detached, the frame is able to receive (can accommodate) either a CF card or a PCMCIA card. In alternative embodiments, the frame accommodates other host processing system connector interfaces. Embodiments of the invention, therefore, allow a production run that allow the production of a standard frame kit that can be used for multiple types of host processing system connector interfaces.
In the following description, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known structures and techniques have not been shown in detail. Reference throughout the specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Similarly, it should be appreciated that in the foregoing description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of this invention.
Depending on the outline that needs to be achieved, cuts can be performed at several locations, such as 220a and 220b, 221a and 221b, 222a and 222b, 223a and 223b, and 224a and 224b, resulting in a variety of slightly different frames that essentially approximate the conventional frames described in reference to
Additionally, ground pins 231a and 231b are embedded, and an opening for light pipe 203 is provided. Light pipe 204 and two potential locations for a signal lamp (e.g., an LED) are provided as well, namely 205a and 205b. The location of the signal lamp is dependent on the form factor chosen and the PCB available. In an alternative embodiment, light pipe opening 203 and light pipe 204 could be located on the other side of the frame kit.
Alternatively, the entire frame kit could be illuminated by use of translucent plastic for the frame kit, or the light pipe might be on the outside of the frame, forming sort of an exterior rail.
At operation 410, a manufacture determines a desired host processing system connector interface (e.g., PCMCIA or CF) from among those which the frame can accommodate.
At operation 415, one or more specific limbs are detached from the frame such that the remaining limbs provide a frame that accommodates the desired host processing system connector interface. For one embodiment, the limbs are made of plastic approximately 1 mm thick, and can therefore be easily detached by a cutting process during manufacturing. Alternatively, or additionally the limbs may be perforated to facilitate cutting. For one embodiment, the limbs are detached through an automated process.
While the invention has been described in terms of several embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described, but can be practiced with modification and alteration within the spirit and scope of the appended claims. The description is thus to be regarded as illustrative instead of limiting.
