摘要:
The invention is directed to compositions comprising polyvalent complexes containing a biocompatible polymer backbone to which is attached a plurality of monomeric anti-microbial peptides and to methods for using such complexes to stabilize anti-microbial peptides for treating or preventing a disease or condition resulting from infection with a microbe. Multivalent derivatives of existing antimicrobial peptides in which several peptides are covalently linked have been investigated. The resulting construct may contain up to 30 or more units, and exhibits a significant enhancement of anti-microbial effect relative to the free peptides: on the order of a ten fold improvement in effectiveness, suggesting that higher multimerization can indeed lead to more effective agents. The invention is also directed to the use of such complexes for delivery of anti-viral peptides, in particular, peptides and peptide fragments obtained from salivary agglutinin protein (gp-340) for use in treating or preventing infection with HIV.

Methods, systems and apparatuses for using wireless access points to identify points of interest (POIs), are disclosed. One embodiment includes a method of using wireless access points to identify points of interest (POIs). The method includes collecting wireless access data points, wherein the wireless access data points comprise at least one wireless access point signature of at least one wireless access element of the wireless access points, analyzing the wireless access data points over a time window, comprising identifying segments within the time window, and matching a point of interest (POI) with each identified segment.

Methods and apparatuses are provided for facilitating gesture recognition. A method may include constructing a matrix based at least in part on an input gesture and a template gesture. The method may further include determining whether a relationship determined based at least in part on the constructed matrix satisfies a predefined threshold. In an instance in which the relationship does not satisfy the predefined threshold, the method may also include eliminating the template gesture from further consideration for recognition of the input gesture. In an instance in which the relationship satisfies the predefined threshold, the method may further include determining a rotation matrix based at least in part on the constructed matrix. Corresponding apparatuses are also provided.

The present invention concerns methods for efficiently supporting Voice over Internet Protocol (VoIP) on the Forward Packet Data Channel (F-PDCH) in CDMA 2000 1xEV-DV systems. Active speech in VoIP is encoded using, for example enhanced variable rate codec (EVRC), which produces 171, 80 and 16 bits per 20 ms of speech for Rate 1, Rate ½ and Rate ⅛, respectively. However, about 60% of the time a user is inactive during a speech session, so an inordinate amount of system bandwidth is comprised of rate ⅛ VoIP packets. In one embodiment of the present invention the apparatus of the present invention identifies the Rate ⅛ voice frame packets and discards them. In another embodiment of the present invention, the apparatus of the present invention identifies the Rate ⅛ voice frame packets and selects some of them for further transmission. In both embodiments the efficiency of channel utilization is increased since the amount of channel band width used to communicate relatively little information, e.g., gaps of silence, is decreased.

An approach is provided for user interaction via transponders (e.g., near field communication (NFC) tag, radio frequency identification (RFID) tag, or contactless card) disposed on a dynamically reconfigurable display. Each transponder corresponds to an area of the display that is associated with one or more actions. The actions are dynamically updated based at least in part on the content presented on the respective area of the display. A user equipment containing a transponder reader detects a signal from one of the transponders to trigger the corresponding action.
摘要:
The present invention relates to a method of compressing or decompressing a signaling message in a packet data network, wherein a parameter information is provided in a header portion of a protocol message of the packet data network. The parameter information specifies at least one processing detail of a compression or decompression mechanism and is forwarded together with the protocol message through the packet data network to a compression or decompression function of the packet data network. The compression or decompression mechanism at the compression or decompression function is then set in accordance with the parameter information. Thereby, a better compression of the first or first few messages can be achieved, as the parameter information is directly available.
摘要:
Signaling between a terminal equipment and a session server is provided which carries information on an expected media stream to or from the terminal equipment via a middle box for optimizing the performance of data communications between the terminal equipment and a correspondent node. On the basis of this information the session server is enabled to create appropriate entries in a security entity provided for the terminal equipment so that the media stream can successfully traverse the middle box and the security entity.
