Abstract: A method and system for detecting short-term stress of a subject person and generating alerts in an indoor environment are disclosed. The system may receive data on the subject person's heart rate, galvanic skin response, and accelerometer movement from a wearable device, and also capture image frames through a camera. After that, the system may perform bio-signal analysis in accordance with the heart rate and the galvanic skin response data, and perform skeletal motion analysis in accordance with the image frames. Based on bio-signal index and skin conductance index generated from the bin-signal analysis and skeletal motion analysis respectively, the system may perform data fusion to determine the short-term stress.

Abstract: For an augmented reality (AR) content creation system having a marker database, when a user requests this system to use a first sub-image of an image to update the marker database, this system computes a suitability score of the first sub-image for rating feature richness of the first sub-image and uniqueness thereof against existing markers in the marker database. When the suitability score is less than a threshold value, a second sub-image of the image having a suitability score not less than the threshold value and completely containing the first sub-image is searched. Then the second sub-image, the suitability score thereof and the suitability score of the first sub-image are substantially-immediately presented to the user for real-time suggesting the user to use the second sub-image instead of the first sub-image as a new marker in updating the marker database to increase feature richness or uniqueness of the new marker.

Abstract: A method for delivering distance education for real clients, each either a teacher client or a student client, at multiple teaching sites and a system using the method are provided. A multi-layer arrangement is used to arrange computing servers to be one first-level server and one or more second-level servers each communicable with the first-level server. Each server serves real clients located in a pre-determined site. Furthermore, each server sets up a virtual client to execute the teacher client's activity command so as to locally generate application-specific data, which are then stored in this server. When a communication link to a student client is re-established after an activity interruption, resynchronization of the student client's learning-activity state with the teacher client's is regained based on the locally-generated application-specific data stored in the server that serves the student client without a need to burden other servers.

Abstract: The present invention includes apparatuses, systems, and methods for peer group formation for mobile devices by proximity sensing. The described embodiments further include methods, systems, and apparatuses configured to easily establish an ad-hoc peer network in which each of the devices in the network automatically discovers and is connected to other devices in the network upon establishing a connection with at least one member of the ad-hoc network. The connection is established using a tap of NFC devices in the two wireless devices. Further, the wireless devices in the ad-hoc network may be divided into logical peer groups.

Abstract: A process of controlling a flow of data in a wireless network providing wireless access to the wireless network by wireless devices is disclosed. Data is received from a wireless device by a network device, through one access point of a plurality of access points in communication with the network device, indicating a client identifier for the wireless device. The client identifier is forwarded to an authentication server and the network device mediated authentication of the wireless device with the authentication server. Thereafter, data packets received from portions of the wireless network and from the plurality of access points are evaluated and the received data packets are passed to portions of the wireless network and to the plurality of access points, based on the evaluation of the received data packets. In addition, the network device periodically polls for a status of the wireless device from the access point.

Abstract: A method of error correction for a multicast message sent over a wireless network includes encoding a message into N data packets using a forward error correction code and multicasting at least L data packets of the N data packets over a wireless network to recipients. Recipients not receiving the at least L data packets send a reply to the sender. The sender then selects a second subset of X data packets from the N data packets, and multicasts the X data packets over the wireless network to the recipients.

Abstract: A device for participating in a distributed peer-to-peer communications network has a distributed network application that includes a capability-routing entity having capability information for a group of associated peers participating in the network. A method for establishing peer-to-peer communication in the network including determining which of the group of associated peers can fulfil the requested connection based in the capability information and referring the request to the peer that can fulfil the connection.

Abstract: A method of providing data to two client devices on a first network having a shared cache from a server device on a second network. An instance of substantially simultaneous requests for data being made to a server from two client devices on a same network is identified. In response to a first request for the data being received at a first point in time a first one of the two client devices is served with the requested data from the server such that the data is stored in the shared cache. The second one of the two client devices is directed to make a second request for the data at a second point in time, later than the first point in time, so that the requested data is available in the stored cache.

Abstract: An admission scheme is provided for selective admission of voice data packets to a voice network from a communication network having data and voice packets. The scheme can be implemented using a device such as a network switch. According to the admission scheme, the MAC address of a device is acquired and stored upon admission of the device to the voice network. The source MAC address of data packets is checked before the packets are admitted from the communication network to the voice network. A packet is admitted to the voice network only if the MAC address is registered with the voice network.
