Apparatuses and methods for determining and applying receiving sensitivity threshold and/or energy detection threshold values for one or more nodes of a wireless network cell are described herein.
摘要:
Briefly, some embodiments of the invention provide devices, systems and methods of selectively establishing a wireless communication link. For example, a method in accordance with an embodiment of the invention may include selecting to transmit data either via a direct wireless communication link or via an indirect wireless communication link based on an efficiency-related criterion associated with said direct and indirect links.
摘要:
A method, device and system for limiting the minimum data rates that will be supported for an association with an access point to for example data rates that are faster than a rate supported by a wireless communication standard that is used in the association, and for rejecting associations that use data rates below the desired rate, even though such data rates would otherwise be feasible for the association.
摘要:
Briefly, a method and apparatus to acknowledge multicast transmission by a station. The station may transmit acknowledgement signal over a dedicated frequency sub-channel which may be allocated by an access point.
摘要:
Briefly, a method and apparatus that may detect hidden nodes in BSS based on a hidden node report that may be generated in an access point based on nodes reports received from stations of the BSS. The access point may enable and/or disable a hidden node protection mechanism and/or may control the transmit power of the stations.
摘要:
Briefly, a method and apparatus that may enable and/or disable of a packet protection mechanism based on a value of an adaptable threshold. The value of the adaptable threshold may be determined from a collision rate of packets transmitted over a wireless local area network and from detection of hidden nodes.
摘要:
A method for detection of underground anomalies including in a system of distributed antennas (10), which are leaky transmission lines, disposed in 16 boreholes (12) formed in a ground, a transmitter (14) being connected to one of the antennas (10), and a receiver (16) being connected to another of the antennas (10), injecting an electromagnetic pulse into one of the antennas (10), wherein the pulse gradually leaks out, and wherein if a speed of propagation in the line in which the pulse is injected is faster than a speed of propagation in the ground, a shock wave is transmitted through the ground, called a transmitted signal, and received as a received signal at another of the antennas (10), and wherein an underground anomaly diffracts the shock wave, resulting in a detectable disturbance in the received signal, and locating the anomaly as a function of a time delay of the disturbance relative to the transmitted signal.
摘要:
An apparatus and method are described for multiplying and adding matrices. For example, one embodiment of a method comprises decoding by a decoder in a processor device, a single instruction specifying an m-by-m matrix operation for a set of vectors, wherein each vector represents an m-by-m matrix of data elements and m is greater than one; issuing the single instruction for execution by an execution unit in the processor device; and responsive to the execution of the single instruction, generating a resultant vector, wherein the resultant vector represents an m-by-m matrix of data elements.

Apparatus for determining a location of a target, the apparatus comprising: first and second magnetic dipole beacons positioned at substantially a same spatial location having respectively first and second time dependent magnetic moments oriented in different directions that generate first and second magnetic fields having different time dependencies; at least one magnetic field sensor coil located at the location of the target that generates signals responsive to the first and second magnetic fields; and circuitry that receives the signals generated by the at least one sensor coil and processes the signals responsive to the different time dependencies of the magnetic fields to determine a location of the at least one sensor coil and thereby the target.
摘要:
In one embodiment, the present invention includes a device that has a device processor and a device memory. The device can couple to a host with a host processor and host memory. Both of the memories can have page tables to map virtual addresses to physical addresses of the corresponding memory, and the two memories may appear to a user-level application as a single virtual memory space. Other embodiments are described and claimed.
