According to an embodiment of the present disclosure, there is provided a system, including: a first wearable instrument; a second wearable instrument including a biometric sensor; an electrical connection between the first wearable instrument and the second wearable instrument; and a strap, sized and dimensioned to be disposed about a wrist. The electrical connection may be capable of connecting the first wearable instrument to the second wearable instrument when the second wearable instrument is at a first position on the strap relative to the first wearable instrument, and of connecting the first wearable instrument to the second wearable instrument when the second wearable instrument is at a second position on the strap relative to the first wearable instrument.

Abstract: A method and a wireless device for exchanging messages with an access point (AP) while the wireless device is in a pre-associated state during which the wireless device is unauthenticated and is not associated with a network. The wireless device receives a beacon from the AP indicating that the AP will protect messages communicated with the wireless device. The wireless device then sends to the AP a message including a request for information from the AP. The wireless device obtains a public key of the AP, and receives an encrypted response to the request and an encrypted symmetric key. The wireless device decrypts the encrypted symmetric key using the public key of the AP to recover a symmetric key that is not encrypted, and decrypts the encrypted response to the request using the decrypted symmetric key to recover a response to the request that is not encrypted.

Abstract: In some examples, a wireless device includes a communication interface to communicate with a wireless network, and at least one processor configured to, receive, from an access point (AP), information including a network address policy of the wireless network. The at least one processor is configured to further, in response to the information including the network address policy, use an address of the wireless device according to the network address policy.

Abstract: In some examples, a system includes a plurality of network controllers, a WI-FI wireless local area network (WLAN) over which at least a first network controller and a second network controller of the plurality of network controllers are to communicate, wherein a link between the first network controller and the second network controller through the WI-FI WLAN is a synchronized link.

Abstract: In some examples, an electronic device receives configuration information relating to network connectivity with a network of a vehicle, the configuration information including a credential. The electronic device establishes, using the configuration information, a connection with the network of the vehicle to access a service, and revokes the credential in response to a termination of the access of the service.

Abstract: Techniques for database normalization recommendation and transparent database normalization are described. A normalization engine can analyze the data stored by database tables to determine scenarios in which normalization of the tables may be beneficial. The normalization engine can recommend normalization to an end user, such as during a database migration process. The normalization engine can alternatively perform row-by-row or complete columnar normalization and cause queries issued against normalized tables based on the previous table schema to be automatically rewritten to adhere to the updated data layout.

Abstract: Technologies are described for adaptive selection of user to database mapping. An impact to processing resources by a user of a database managed by the processing resources may be predicted using criteria based on user-database properties such as a number of rows in database, a number of rows in database for the user, a maximum depth of hierarchy for the user, a maximum breadth of hierarchy for the user, applications that have recently accessed the user's data, distribution of quota types in the user's data, a number of shared items in the user's hierarchy, a number of people who share in the user's shared item hierarchy, an application employed by the user to access the data currently, etc. Based on a model for the predicted impact, a behavior change (for any of the criteria) and/or a move of the user to another database may be suggested/automatically implemented.

Abstract: There is provided a three-dimensional (3D) printer for creating a 3D object using a fabric including a cutting device, an inverted cutting surface, a securing mechanism to secure the fabric against the inverted cutting surface for cutting the fabric by the cutting device into a plurality of layers, a movable platform for receiving each of the plurality of layers, in sequence, from the inverted cutting surface after each layer is cut from the fabric, and a bonding tool to bond each layer of the plurality of fabric layers to a previously received layer as the fabric layers are sequentially received by the movable platform to create the 3D object.

Abstract: One exemplary embodiment involves receiving an image with a set of undefined pixels and a set of defined pixels and recursively modifying the image to generate a seamless composition comprising only defined pixels. Disclosed are embodiments for recursively modifying the image by recursively down sampling the image by a factor to generate a plurality of down sampled images until the down sampled image generated at each recursive down sampling lacks undefined pixels and then recursively up sampling each one of the down sampled images by the factor to generate an up sampled image from the respective down sampled image. Additionally, at each recursive up sampling instance, pasting the next recursively occurring down sampled image on the up sampled image to generate the next recursively occurring image for up sampling.

Abstract: A key distribution scheme is provided, which is useful for establishing, distributing, and maintaining security associations in a Mobile IP network. An authentication server performs an initial validation of a new session and generates a root key which it delivers to the initial access gateway and to the home agent. The initial access gateway and the home agent each independently compute a derivative key available only to themselves. The initial access gateway, acting as proxy for the mobile station, uses the derivative key to sign the Mobile IP registration or binding update transactions, and sends the signed registration or binding update to the home agent for validation. Once the session is established between the mobile station and the home agent, the access gateways act as proxies on behalf of the mobile station to maintain the session mobility. In handoff, the new access gateway acquires the root key as part of the transferred session context.

Abstract: A method is provided for controlling communications to and from an access terminal during a hand off period. A smart packet filter is used to identify a packet flow, apply a first treatment to a packet flow based on its destination, and transmit the first treated packet flow along a first route to the access terminal. During a hand off, the packet stream is duplicated, a second treatment is applied to the packet flow and the second treated duplicate packet flow is transmitted to the access terminal via a second route.

A control component removes one or more encoded frames from the plurality of frames of the isochronous telecommunication stream based on one or more code rates of the one or more encoded frames to create a non-isochronous telecommunication stream.
