摘要:
A method encodes and decodes messages between nodes of a wireless communication network. A first node, such as a fob, is mated with a second node, such as a base station, of the wireless communication network. A time duration of the mating is determined in the fob. The time duration of the mating is also determined in the base station. An encryption key is generated based upon the time duration in the fob. The encryption key is also generated based upon the time duration in the base station. Subsequently, communication messages over the wireless communication network are encrypted and decrypted between the fob and the base station employing the encryption key.

The World Wide Web directory for providing live links includes a search function whereby customers can perform a keyword search of database entries to locate websites having a live link. The search results in a listing of websites matching the customer's request, including for each website a URL for the website and its live link. In addition to searching among the database for live links, customers can submit ratings of the websites. The ratings are displayed along with the listing of websites that match a customer's request. Additionally, website or live link owners can register their websites and manage a list of keywords that will be searched by the search function. Sponsored members are members who pay a fee, or place a bid to pay a fee “per hit”, for more prominent ranking among search results. Websites that don't have a live link are given the lowest priority.

A packaged electrical system includes an enclosure and a main interior volume for component supports. The component supports may support electrical, electronic, power electronic and similar components, as well as switchgear and the like. A main power wireway is provided adjacent to the main interior volume of the enclosure for accommodating three phase power conductors. A network and control power wireway is formed separately from the main power wireway. The network and control power wireway may be formed toward the rear of the main interior volume, and may accommodate plug-in connections between component supports and network conductors and control power conductors. The network and control power wireway is thus accessible through a separate door from the main power wireway.

Systems and methods for detecting degradation and failures, include types of failures, in a hose assembly are disclosed. One system includes a hose degradation monitoring circuit having a hose assembly including a hose having first and second conductive layers, and a degradation monitoring circuit configured to detect a resistance of the hose across the conductive layers. The degradation monitoring circuit includes a voltage source electrically connected to the first conductive layer, and a resistor electrically connected between the second conductive layer and ground. The degradation monitoring circuit further includes a voltage monitoring circuit electrically connected between the resistor and the second conductive layer, to periodically monitor a voltage at the location and detect a possible failure of the hose assembly upon determining that, based at least in part on a change in the voltage at the location over time, a resistance of the hose assembly has passed a threshold level.

A system for pairing wireless nodes includes a plurality of device nodes, such as lamp nodes, a plurality of sensor nodes, such as light switch nodes, and a context manager node. Each of the device nodes, the sensor nodes and the context manager node includes a first communication channel having radio frequency signals and a diverse second communication channel including wireless non-radio frequency signals. Some of the device nodes and the sensor nodes are adapted to collect context information of a corresponding communication environment and to transfer the collected context information to the context manager node. The context manager node is adapted to employ the collected context information and enable automated distributed pairing of a first node of the device nodes and sensor nodes with another second node of the device nodes and sensor nodes.

An ad-hoc network includes an ad-hoc network coordinator (NC) having a first processor, a first memory, and a first communication interface; and a plurality of ad-hoc network devices (NDs). Each of the NDs includes a second processor, a second memory, and a second communication interface structured to communicate with the first communication interface of the NC or with the second communication interface of at least another one of the NDs. The first processor cooperates with at least some of the NDs to globally optimize a route based on a plurality of link costs for: (i) pairs of the NDs, or (ii) pairs of the NDs and at least one pair including one of the NDs and the NC, in order to minimize cost along the route that: (a) one of the NDs or the NC employs to send a packet to: (b) another one of the NDs or the NC.

A reduced form factor component support is provided for motor control centers and similar packaged electrical systems. The reduced form factor component support may be used with smaller components, such as small motor starters, motor drives, and so forth. Electrical connections with standard bus bars in the enclosure are made through special connectors mounted on subplates in the rear of the enclosure, or by an invertible stab housing that can allow the reduced form factor component support to share conventional slots in a bus cover, thereby providing access to the supply power in the enclosure.

A sensor node or a control device node is for a home system including a server and a fob. The node includes a household object, and a sensor, control or display device embedded in or substantially within the household object. The sensor, control or display device includes a first wireless port adapted to wirelessly communicate with the server, a second port adapted to communicate with the fob when the fob is proximate to the second port, and a processor operatively associated with the first wireless port and the second port. The processor is adapted to receive proximity information from the second port and responsively communicate with the server through the first wireless port, in order to configure the sensor, control or display device.
