Abstract: A swivel nozzle mechanism used with a high pressure fluid washer attaches to an output wand, typically through a flexible hose, to direct a high pressure fluid from the washer to a directed target. The swivel nozzle mechanism attaches to a distal end of the wand and is controllable by a handle mechanism attached to the wand which enables the rotation of a spray nozzle about an axis, normal to the wand axis, at the distal end of the wand. The handle controls the direction of rotation of the spray nozzle and has a plurality of stable operating points resistant to movement and thereby providing for prolonged use at a fixed position.

Abstract: AC generators are disclosed. Example generators may include a tubular air core, with high magnetic permeability and with a first and second end, the air core having a plurality of eddy current reducing slits passing from a radially outer surface of the air core to a radially inner surface of the air core; and a continuous coil made of conducting wire having a plurality of loops wrapped around the air core, the coil positioned between the first end and the second end of the air core.

Abstract: A method, apparatus, and medium are provided for tracing the origin of network transmissions. Connection records are maintained at computer system for storing source and destination addresses. The connection records also maintain a statistical distribution of data corresponding to the data payload being transmitted. The statistical distribution can be compared to that of the connection records in order to identify the sender. The location of the sender can subsequently be determined from the source address stored in the connection record. The process can be repeated multiple times until the location of the original sender has been traced.

Abstract: Programmable occupancy sensors that control the on/off operation of a fluorescent lamp automatically determine loss of lamp life as the lamp is used. The programmable occupancy sensors can provide lamp life status and can automatically alert a user when a lamp is nearing its end of life and should be replaced. The occupancy sensors are also programmable to automatically improve lamp life and energy savings by selecting an optimal time delay from among a number of selectable time delays at which to operate the sensor. The selection is based on an occupancy pattern sensed by the sensor over a given period of time. The optimal time delay, which prevents the lamp from turning off immediately after last sensing occupancy, extends lamp life by limiting the number of lamp off/on transitions, which shortens lamp life, in view of overall energy usage and lamp usage.

Abstract: Systems and methods for computing data transmission characteristics of a network path are disclosed. In some embodiments, the network path has a sending host, at least one intermediate host, and a receiving host, and the data transmission characteristics are computed based on single-ended measurements performed at the sending host.

Abstract: Methods, media, and devices for providing visual resources of video conference participants are provided. In some embodiments, methods for providing a visual resource of a participant to a video conference comprise: determining that the participant is joining or departing the video conference; accessing a visual resource that identifies the participant; and presenting the visual resource to at least one other participant to the video conference.

Abstract: A media portal is provided that is used to connect multimedia devices to other multimedia devices and content servers. When a call directed to a multimedia device busy in a call with the media portal is received, the media portal can provide a call waiting indication to the busy multimedia device without breaking the connection that is making the device busy. For example, if a first multimedia device is connected through the media portal to a content server providing streaming content of a football match, when a second device attempts to place a call to the first device, the media portal can provide a call waiting alert to the first device as part of, or as a substitute for, the delivery of the football match. Additionally the media portal can provide for the eventual connection of both devices while the previous call is still active.

Abstract: Devices, methods, and media for providing multi-point video conferencing unit functions are provided. In some embodiments, devices for providing multi-point conferencing unit functions comprise: a combination of at least one input interface that receives a plurality of video signals, and that receives a visual layout from an EMCU end-point; a processor that selects a subset of the plurality of video signals; a combination of at least one output interface that sends the subset of the plurality of video signals to the EMCU end-point and that sends the visual layout to a video conferencing end-point, wherein the visual layout incorporates the subset of the plurality of video signals.

Abstract: In a trading environment that comprises buy side traders and securities brokers, a computer process capable of preventing securities brokers from receiving information irrelevant to a commission payment for a securities transaction. The process comprises means for providing an overview of commission payments for a predetermined time period, means for providing details of step-out payments for the predetermined period, means for adjusting step-in amounts and frequencies, means for providing notification that a commission payment has been stepped out and is capable of being credited, means for automatically suggesting and performing step-ins and step-outs, and means for assessing the step-outs and step-ins against a predetermined budget.
