July 9, 2014



By a News Reporter-Staff News Editor at Telecommunications Weekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors McCormack, Gary D. (Tigard, OR); Isaac, Roger (San Jose, CA), filed on December 14, 2013, was made available online on June 26, 2014.

No assignee for this patent application has been made.

News editors obtained the following quote from the background information supplied by the inventors: "It is often important to transfer data between electronic devices. The data may comprise a media file (such as an image file, an audio file, a video file), DRM (digital rights management) protected content, an OS (operating system) update, customer specific code, OEM (original equipment manufacturer) specific code, retail specific code, a firmware image for the destination device, user data, encryption/decryption keys (codes), electronic funds transfer (EFT) data, static data and the like. The data may be transferred from a 'source' (or sending) device such as a digital camera to a 'destination' (or receiving) device such as a laptop. In some cases, data may also be transferred in the reverse direction, with the 'destination' device serving as the source of the data, and the 'source' device serving as the destination for the data. The transfer of data may occur via a communications link such as a cabled connection (such as USB), or via a wireless connection (such as Bluetooth). In the case of DRM or other access-controlled content, separate authorization (codes) may be required for using the data on the destination device.

"Some examples of electronic devices which may be involved in the transfer of data include cell phones (or handsets, or smart phones), computers, laptops, tablets, or comparable electronic device Such electronic devices typically include a 'host processor' (or microprocessor or simply 'processor', or microcontroller, or '.mu.C'), and resources (memory or storage) for storing data (any of which may be referred to simply as 'storage').

"In the main hereinafter, point-to-point connection-oriented techniques for data transfer between two electronic devices will be discussed. Generally, in order for the data transfer (which may be referred to as 'uploading' or 'downloading') to occur, both devices need to have compatible software installed so that they can have access to one another. During the data transfer, the devices need to be turned ON (operating), consequently system resources are consumed and for battery-operated devices, remaining (available) battery power diminishes.

"An illustrative example of a point-to-point, connection-oriented communications link for transferring data between electronic devices is Near Field Communication (NFC). NFC implements a set of standards for smartphones and similar devices to establish radio frequency (RF) communication with each other by touching ('bumping') them together or bringing them into close proximity with one another. Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. Communication is also possible between an NFC-enabled device and an unpowered NFC chip, called a 'tag', which may harvest its operating power from the NFC-enabled device.

"When transferring data between electronic devices, it is generally necessary that the devices' host processor(s) become involved and that data is transferred under its (or their) direction and control. When a data connection is made, the host processor is typically notified, then may authenticate the connection, and if there is a data transfer to be made, the host processor allocates memory for the data (or identifies the data that will be transferred) and then directs the action. At the end of the transfer, the host processor then validates the transaction. This process requires that the host processor be aware of and direct the transaction. This method of transferring data between electronic devices may create a number of problems, such as: the host processor must be ON (powered up) for the data transfer to take place; the host processor must be configured for the data transfer to take place; the overall system power consumption is higher than if the host processor were not involved; the data may be malicious code and may cause problems if being handled by the host processor the transfer time for the data, using NFC or other existing wireless technologies, may be very long"

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "In one embodiment, a system for ad-hoc file transmission may comprise a first portable electronic device and a second portable electronic device. The first portable device may include a first memory, a first processor operationally coupled to the first memory, and a first EHF communication unit operationally coupled to the first processor. The second portable device may include a second memory, a second processor operationally coupled to the second memory, and a second EHF communication unit operationally coupled to the second processor. The first memory may include at least one file. The first and second processors may be configured to establish an EHF communication link between the first and second EHF communication units, and to transmit a copy of the at least one file to the second memory via the EHF communication link.

"In another embodiment, a system for synchronizing a digital media file via short-range EHF communication may comprise a first portable electronic device including a first memory unit for storing one or more digital media files, a first processor coupled to the first memory unit, and a first EHF communication unit coupled to the first processor. The first EHF communication unit may be configured to establish an EHF communication link with a second EHF communication unit. The first processor may be configured to transmit a selected digital media file of the one or more digital media files from the first memory unit to the second EHF communication unit via the EHF communication link.

"In another embodiment, a method for transmitting one or more files to a second electronic device may comprise a step of forming by a first electronic device an EHF communication link with the second electronic device when the second electronic device is in close proximity to the first electronic device; a step of producing by the first electronic device a list of one or more files that are accessible to at least one of the first and second electronic devices and are available to be shared; a step of receiving, at the first electronic device, an identification of a file from the produced list; a step of formatting at the first electronic device a data package that includes file information for the identified file; and a step of transmitting the data package from the first electronic device to the second electronic device using the EHF communication link. The file information may be the identified file, a copy of the identified file, or a link to a remote server on a network where the identified file is stored.

"In another embodiment, a method of synchronizing a digital media file from a first electronic device to a second electronic device may comprise a step of establishing an EHF communication link between the first electronic device and the second electronic device; a step of displaying, on at least one of the first and second electronic devices, a list of one or more digital media files stored on the first electronic device; a step of receiving, at the first electronic device, an identification of a digital media file to share with the second electronic device from the list of digital media files; a step of formatting a data package at the first electronic device, where the data package is formatted for transmission over the EHF communication link, and the data package includes a copy of the identified digital media file; and a step of transmitting the data package from the first electronic device to the second electronic device via the EHF communication link.
