摘要:
A technique allows a parentally attested security token to serve as authentication for a minor using identifying attributes of the minor child. The security token may include personally identifiable information about the child, a description of authorized activity as well as specifications of intended use of the security token. The security token may include provisions for authentication to be revoked by a parent or guardian and/or expire after a predetermined time. The security token may be stored inside a trusted execution environment of a portable computing device that may be carried by the minor and presented at physical locations where authentication is required.

Methods, apparatus, systems and articles of manufacture are disclosed to pair devices to an in-body network. An example apparatus disclosed herein includes a device capability manager to identify remote sensors associated with a candidate medical device, an encryption engine to provide the candidate medical device with hashing instructions to be applied to input values from selected ones of the remote sensors, a measurement engine to acquire input values from local sensors corresponding to the selected ones of the available remote sensors during a measurement schedule, the encryption engine to apply the hashing instructions to the input values from the local sensors, and a pairing engine to authorize the candidate medical device when an encryption key associated with the remote sensors includes a threshold indication of parity with an encryption key associated with the local sensors.

Described herein are techniques related to inferring context information for a piece of content. A client context agent infers the context information by associating the piece of content with information in the computing environment. The association may be made in response to a user interaction with the piece of content in an application, and the information in the computing environment is external to the application. For example, if a user sends an email, the client context went may use a keyword analysis to associate the email with a web page that is open concurrently, and then embed as evolving metadata the Uniform Resource Identifier (URI) of the web page in the email. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要:
The present invention discloses a method comprising: acquiring an image; digitizing the image; selecting one or more rows from a portion of the image; performing a line scan of the selected rows; retrieving a reference scan; comparing the line scan with the reference scan; identifying a feature; and categorizing the image.

Methods of radiofrequency identification and analysis are disclosed. In one aspect, a method may include transmitting a wireless interrogation signal. Corresponding wireless response signals may be received from each of a plurality of transponders. Then, analysis of interrelationships between different types of objects each associated with one of the transponders may be performed. Software and apparatus to perform such methods are also disclosed. In another aspect, a method of radiofrequency identification may include accessing additional information about one or more objects that are each associated with a different one of the transponders from a peripheral database.
摘要:
A high voltage electrochemical cell is provided which includes an active metal as anode, such as sodium, a mixture of a transition metal halide or sulfide, e.g. CuCl.sub.2 and graphite as the cathode and an electrolyte of a room temperature chloroaluminate molten salt such as MEIC-AlCl.sub.3 buffered to Lewis acid-base neutrality by an excess of metal halide, such as NaCl, to provide a discharge potential or open-circuit voltage of up to 2.78 V or more. The battery cell of the present invention is believed the first to use sodium as an active metal anode in a room temperature, molten salt electrolyte. The battery cell of the present invention is useful for long-life, low drain applications, e.g. remote sensors and surveillance equipment.
摘要:
Methods and apparatus relating to multi-factor authentication based on image feedback are described. In an embodiment, authentication logic, at a first computing device, authenticates a second computing device based at least partially on a comparison of a unique identifier, to be generated for the second computing device and to be displayed on a display device of the first computing device, and a detected unique identifier to be received from the second computing device. Other embodiments are also claimed and described.
摘要:
An ambulatory system to communicate visual projections. An embodiment of an apparatus for ambulatory communication includes: a propulsion system to enable the apparatus to fly, including to hover in place and to follow a user; a stereo camera to record an image of a user of the apparatus or a scene nearby the user of the apparatus; a transmitter to transmit video data generated by the stereo camera to a second apparatus via network for a communication with a remote user; a receiver to receive video data via the network from the remote user; and a video projection mechanism to project an image including the received video to the user.
摘要:
Digital image processing of a low resolution source image to produce a high resolution result image may be accomplished by partitioning the low resolution source image into a plurality of low resolution image parts; for each low resolution image part, comparing the low resolution image part to low resolution reference images to determine at least one most similar low resolution reference image; determining if the most similar low resolution reference images are related to one another; and constructing a high resolution result image based at least in part on high resolution images corresponding to related most similar low resolution reference images.
