Abstract: A method includes receiving, with a processor in communication with a first exercise machine, a first request for an exercise class, the first request being provided by a first user of the first exercise machine. The method also includes providing a video file associated with the exercise class to the first exercise machine, providing a notification to a second user indicating that the first user has chosen to participate in the exercise class, and receiving a second request for the exercise class provided by the second user. The method further includes providing the video file to a second exercise machine of the second user via the network. In such a method, display of the video file via a display of the second exercise machine is synchronized with display of the video file via a display of the first exercise machine.

Abstract: An exercise machine includes a processor, a first display, a deck, and a belt rotatable about the deck. The machine also includes a sensor operably connected to the processor and configured to detect a first performance parameter of a first user running on the belt of the exercise machine.

The processor is also configured to cause the second performance parameter to be displayed on the first display together with the first performance parameter.

Abstract: A probabilistic framework to detect controversy on the web. The prior kNN-WC algorithm is recast into a theoretical framework and a new language model introduced. Language models are constructed that are used to calculate probabilities. The probabilities are compared to determine whether or not a certain document is controversial.

Abstract: Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight and whether the container weight is below a pre-established threshold, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.

Abstract: Methods are provided for collecting platelet-rich plasma. A disposable flow circuit is mounted to a fluid processing device having a fluid separation chamber and an injection device. A fluid containing plasma and platelets is continuously conveyed from a fluid source into the fluid separation chamber and processed to produce platelet-rich plasma. At least a portion of the platelet-rich plasma is automatically conveyed from the fluid separation chamber into the injection device, which is directly connected to a pump device such that at least a portion of the platelet-rich plasma from the fluid separation chamber is automatically conveyed into the pump device prior to being conveyed into the injection device. The injection device with the platelet-rich plasma is then detached from the disposable flow circuit.

Abstract: An implantable lead including a lead body, an electrode coupled to the lead body, and at least one cellular modulation segment. The lead body has a proximal end and a distal end. The lead body includes an outer layer defining a lumen. The outer layer has an outside surface. The electrical conductor is disposed within the lumen of the outer layer. The electrode is coupled to the lead body. The electrode is in electrical communication with the electrical conductor. The at least one cellular modulation segment is on the outside surface of the outer layer. The at least one cellular modulation segment includes topographic surface features configured to modulate cellular responses. The topographic surface features include a plurality of raised nodes and a plurality of raised ridges interconnecting the plurality of nodes and forming a lattice structure.

Abstract: A man-worn power and data harness. The harness is intended to facilitate the supply of power and data around a user's, and in particular a soldier's, person. Furthermore, the harness is intended to be compatible with a tiered structure of soldier load carriage and protection. The harness may comprise: at least one brace for passing over a user's shoulder, each brace comprising at least one cable; and a belt for at least partially encircling a user's waist, the belt comprising at least one cable; wherein each cable comprises power and/or data cabling, each brace is connected at both ends to the belt and each brace comprises at least one release clip, the release clip being for disconnecting and reconnecting the brace; each brace may further comprise at least one attachment device to attach the brace to an item worn underneath the harness. Furthermore, a harness and load carriage may be provided.

Abstract: A method of providing anti-replay protection, authentication, and encryption with minimal data overhead is provided. A sender uses an arbitrary-length pseudorandom permutation to encrypt messages that include plaintext and successively increasing sequence numbers, to produce ciphertext messages. The sender transmits the ciphertext messages. A receiver receives the ciphertext messages and, for each received ciphertext message, performs the following operations. The receiver decrypts the given ciphertext message to recover plaintext and a candidate sequence number from the message. The receiver determines if the candidate sequence number is in any one of multiple non-contiguous acceptable sequence number windows having respective sequence number ranges that are based on at least one of a highest sequence number previously accepted and a last sequence number that was previously rejected, as established based on processing of previously received ciphertext messages.

Abstract: In one implementation, network taps are detected using impedance measurements from a network. A network device is configured to calculate a baseline impedance as a function of a sequence of impedance values. As impedance measurements subsequent to the sequence of impedance values are received, the network device is configured to calculate a difference between the impedance measurement and the baseline impedance. The network device generates a network tap warning message when the difference between the impedance measurement and the baseline impedance exceeds a threshold. The network device may be an endpoint computer, a data switch, or an external device remote from the network.

Abstract: An un-authenticated user attempts to access a protected resource at a Web- or cloud-based application from within a rich client. The client has an associated local HTTP server. Upon being refused access, a browser-based login dialog is opened automatically within an embedded browser panel. After receipt of the user's login credential in the panel, the browser passes the credential server application. If the user is authenticated, the browser-based dialog receives a cookie establishing that the user is authenticated for a session. The browser then automatically makes a request to the HTTP server, passing the cookie. Upon receipt of the request at the rich client HTTP server, the rich client saves the cookie in an associated data store, shuts down the login dialog, and re-issues the original request to the server, this time passing the cookie. The rich client, having provided the cookie, is then permitted to access the resource.
