Abstract: A system and method for achieving enhanced CSMA/CA which improves channel availability and quality of service (QoS) in a wireless communications network. The system and method establish channels to enable communication between nodes in a communication network, based on the relationship between the average time length of message data packets and the time lengths of the request to send and clear to send messages. A node of the communication network places a data packet at a location in a queue for retransmission based on a type of information contained in the data packet if the destination node for which the data packet is intended is unable to receive the data packet. The location in the queue is indicative of a duration of time that the node will delay before attempting to resend the data packet to the destination node.

Abstract: A system and method for enabling a node in a mobile wireless ad-hoc communications network to use a particular spreading code to spread a message to be transmitted to a destination node without having to provide information on the spreading code to the destination node in, for example, an RTS message, to thus improve the overall efficiency of the network. The system and method enables the node to select the spreading code based on the destination of that transmission message, along with other factors such as network prefix information, time of day, and provider information, to minimize destructive interference between the spread transmission messages transmitted by neighboring nodes in the network.

Abstract: A system and method for detecting communication requirements in a network and placing nodes in various stages of activity where conditions allow. The system and method provides an algorithm to detect changes in node activity levels and alter operations, such as update transmissions and route selections, based upon changes detected. In particular, the algorithm determines activity level at a node at each routing update interval based on factors such as a number of new destinations the node can reach, a number of route modifications that the node can implement, a number of routes from the node whose lengths have changed and a number of destinations the node can no longer reach. The node can then increase or decrease the rate that it exchanges its routing information with neighboring nodes based on an increase or decrease in this activity level.

The exterior of the rope may be covered by a jacket that provides for traction with the drive sheave. An elevator system comprising the claimed rope is also provided.

Abstract: A system and method for providing security to a wireless network by using a mobile node's location as a parameter for deciding if access is to be given to the node. The system and method employ access points, wireless routers and mobile nodes, each including at least one transceiver adapted to transmit and receive communication signals to and from other wireless routers, mobile nodes and other mobile access points. Each access point is connected to a network management system which allows enhanced network monitoring and control.

Abstract: A system and method for providing a congestion optimized address resolution protocol (ARP) for a wireless ad-hoc network. The system and method enables a node in the wireless ad-hoc network to issue an ARP request without the need to broadcast the request to all of the nodes in the wireless ad-hoc network, to thus minimize radio traffic on the wireless ad-hoc network for handling the ARP request. The node includes an address resolution protocol module which is adapted to generate an ARP request for a media access control (MAC) address corresponding to an Internet protocol (IP) address, and a transceiver which is adapted to transmit the ARP request for delivery to an access point of a network portion, such as a core LAN of the network, without broadcasting the ARP request to a plurality of other nodes in the wireless ad-hoc network. The transceiver can transmit the ARP request to the access point directly or via other nodes in the wireless ad-hoc network.

Abstract: A set of programming macros implement bit-fields in a variable, such as an unsigned integer structure having a bit-field definition number associated with each bit-field. The bit-field definition numbers have a value that defines the associated bit-field in terms of its end bits. In various embodiments, the macros extract the end bits from the value of the structure elements to form mask and shift values with which to manipulate the bit-fields.

Abstract: A tee setting device for single-handed setting of a golf ball and tee in the ground at any one of a variety of selected insertion depths, while also adjusting for a range of different tee lengths. The device generally comprises a hollow shaft having a knob and an operating handle at an upper end, a stand-up leg assembly at the lower end, and a tee-setting mechanism at the lower end for controlled insertion and release of a ball and tee in the ground. The tee and ball are inserted simply by gripping the operating handle and pushing it downward. The tee setting device allows golfers to automatically set the ball and tee in the ground, thereby avoiding squatting or bending over the ball. The device is extremely accurate and consistent in setting the height of the ball on tees of various lengths. Moreover, the tee setting device is sized like a playing club or iron, and can be easily manipulated and stowed in the golf bag.

Abstract: Operational parameters for transmitting a signal over a communication channel of a network are selected by first determining RF conditions on the communication channel from a received signal transmitted over the communication channel. An initial set of parameter values is selected for transmitting the signal based on RF conditions determined from the received signal. The initial set of parameter values is used to identify other sets of parameter values as other potential candidates for transmitting the signal. The parameter values in the other sets of parameter values differ from parameter values in the initial set of parameter values by less than a predetermined amount. The expected performance of the candidate sets of parameter values is compared to determine which set of parameter values has the best expected performance among the candidate sets of parameter values. The signal is transmitted on the communication channel using the selected set of parameter values.

Abstract: An IC design is tested on a workstation through a hardware simulator. The workstation includes a co-verification software tool that executes IC firmware to operate the IC design and test the IC design and IC firmware. The co-verification software tool further operates to supply test stimuli to the IC design and to receive responses for analysis. The test stimuli are written in a programming language, which permits ease of testing and analysis of the IC design.

Abstract: Water treatment systems or assemblies are normally tested after construction, at least for leaks, prior to shipping or storage. Pressure testing with a gas is hazardous, so testing with water is a standard method. After testing, the water is displaced from the system by draining or gas phase flushing. It is nearly impossible to remove all of the water from the system or assembly. This remaining water provides an environment for biological growth which contaminates the system or assembly over time. The purpose of this invention is to eliminate or minimize this biological contamination by adding a biocidal agent to the system or assembly before sealing it for shipment or storage.
