Abstract: This idea grasps the use of gravity over gasoline in the moving of cars through drive though lanes at fast food restaurants. The idea involves changing the gradient of the lane such that the driver of a vehicle may enter the drive through lane, turn off the cars engine, and proceed to roll through the lane and order their food without having the engine run. This saves massive amounts of emissions from cars which average about five minutes of idling during each trip, and saves some gas.

Abstract: A mechanism for booking events comprising an event broker, one or more event managers and one or more action handlers. In one embodiment, the event broker is configured to register a plurality of event bookings, each of which identifies an event and a corresponding action. For each event booking, the event broker notifies an event manager which is configured to detect the type of event identified in the event booking. When the event manager detects the identified event, it notifies the event broker. The broker then notifies an action handler which is configured to initiate the type of action identified in the event booking. The action handler then initiates the action. If the event booking is non-recurring and the action is complete, the event booking is unregistered by the event broker. The event broker is configured to work in conjunction with a plurality of event managers which can detect different types of events and a plurality of action handlers which can initiate different types of actions. The event broker is configured to resolve resource conflicts between actions for which the corresponding events have been detected. The event broker is configured to resolve resource conflicts between actions for which the corresponding events have been detected. The event broker is further configured to control access to event bookings through a security system which can use privileges or credentials to identify clients which are authorized to read, modify, delete or otherwise access information contained in the event bookings.

Title: Intelligent inbound/outbound communications blending
Inventor: MAXWELL DARRYL J
IPC: H04M3/42
Filed: 2002-08-20
Abstract: In a blended inbound/outbound call center (100), an outbound call-pacing function (122) decides whether or not to initiate an additional outbound call for a particular skill. It determines (206) whether the number of available agents for the skill plus the number of resting agents for the skill exceeds the number of available inbound calls for the skill plus the number of outstanding outbound calls for the skill. It also determines (312) whether a target service time for the skill exceeds an estimated wait time of each of the available inbound calls for the skill assuming that pending outbound calls for the skill plus one take precedence over the inbound calls. If both determinations are affirmative, the call pacing function initiates (318) an additional call for the skill, If either determination is negative, the function forbears (321) from initiating an additional call for the skill. The number of available and resting agents may be incremented (206) by (a) a difference between the target service time for the skill and the present waiting time of the last-enqueued inbound call for the skill divided by the average rate of advance through the skill's call queue, or (b) the average amount of time that a newly-initiated outbound call for the skill takes to become available divided by the average rate of advance, plus the number of agents for the skill who are busy but expected to become available within a time period equal to (a) or (b), less the number of those agents that will receive a rest period upon becoming idle. The number of calls may be incremented (206) by the number of inbound calls that are expected to arrive within the time period (a) or (b).
