Abstract: Disclosed are a touch sensitive display and a method of operation thereof. The display comprises a sensor having an input put array of electrodes and, capacitively coupled thereto, an output array of electrodes and a controller operable to perform a scan operation at every intersection point of said input array. The scan operation comprises measuring a touch value for an intersection point; determining a proportional difference between said touch value and a base touch value for said intersection point as a proportion of said base touch value, wherein said base touch value is indicative of there being no touch event on the sensor; and comparing the proportional difference to a predetermined proportional touch threshold so as to determine whether there is a touch event at that point.

Abstract: In a communication network (100) comprising a plurality of wireless devices (120), a method determines whether to change one or more communication channels over which the wireless devices (120) communicate. The method includes receiving a plurality of configuration parameters for the communication network (100); receiving information related to one or more communication channel's availability for communications by one or more of the wireless devices (120); and determining whether to change one or more communication channels over which the wireless devices (120) communicate by executing a communication channel change determination algorithm using the configuration parameters and the received information related to one or more communication channel's availability for communications by one or more of the wireless devices (120).

Abstract: The present invention relates to an apparatus, method and computer program product for controlling reception in an asynchronous operation mode, wherein a transmitter sends an extended preamble sequence of length longer than the maximum length of a wake up message itself plus the maximum length of a gap between wake up messages, such that a receiver turning on during a sequence of wake up commands and not detecting the wake up commands, can be sure to successfully detect a preamble if it tries again a second time a set interval later.

Abstract: A location detection system and method with fingerprinting including defining nodes in an area, the area being associated with field devices and a target device; determining expected signal strengths from the field devices at the nodes; measuring actual signal strengths from the field devices at the target device for each of the field devices in communication with the target device; designating as valid nodes the nodes having the expected signal strength for a particular field device that is greater than or equal to the actual signal strength for a particular field device; and determining at least one of the valid nodes for which the actual signal strengths for the field devices agree with the expected signal strengths for the field devices at the at least one of the valid nodes.

Abstract: A method and system to assign a mobile node to a router in a wireless multihop mesh network. A request from a mobile node to join the network is received. A server is notified of the request to join the network, and transmits a positive response to the mobile node upon establishing a connecting between the mobile node and network, and then generates an association record between the mobile node and a router. The association record is then recorded and it is determined if a previous association record exists between the mobile node and at least one other router. If previous association record exists, then a message to suppress any association record between the mobile node and the at least one other router is sent.

Abstract: A method of commanding a first wireless communicating device from a second wireless communicating device, comprising the following steps performed by a main portion of the second device: joining a wireless communication network to which the first communicating device is connected, using procedures of the protocol stack of the first device, thereby obtaining network information for constructing commands for the second device, and making the network information available for the remote control portion, and comprising the following steps performed by a remote control portion of the second device: retrieving the network information from the main portion of the second device, constructing a command message for the first device using a format of the command messages of the protocol stack of the first device and using the retrieved network information, and sending the command message to the first device, using the MAC and PHY layers.

Abstract: The present invention relates to cryptographic secret key distribution, wherein a value for a number of iterations can be individually set, so that the number of messages to be exchanged during generating a cryptographic secret key can be varied based on the set value of the iteration number.

Abstract: An invitation message (112, 116, 120) is sent from a concentrator (102) to nodes in a network. Each node records (124) an identifier (126) of the node or concentrator from which it received the message and forwards (122) the message to its neighbors. A node (108) then sends a trace message (132, 134, 136) to the concentrator (102) via intermediate nodes (106, 104) traversed by the invitation message in reaching the node and appends thereto the identifiers of the intermediate nodes. The concentrator then uses source routing to send a subsequent message (144, 146, 148) to the node (108) using the identifiers included in the trace message. The invitation message and/or the subsequent message includes characteristics) (200) of the concentrator one or more of which are then stored by nodes, including node (108). The characteristic(s) are used in deciding (206, 208) to send further trace messages, thereby regulating use of network bandwidth.

Abstract: A method to assign a mobile node (1) to a router in a wireless multihop mesh network, the network comprising a plurality of routers (3, 5, 7), said method comprises: in a first router (5): receiving (52) from the mobile node a request to join the network; then informing (54) a server (9) that the mobile node has joined or attempted to join the network; and sending (58) to the mobile node a positive response and recording the connection of the mobile node; and in the server (9): recording (60) an association record between the mobile node and the router; and if an association record already exists between the mobile bile node and another router, sending (62) a message to the other router for suppressing any connection record between the mobile node and the other router.
