Patent CA-2286154-A1 (CA)
Inventor: BUHLER KIRK A
IPC: A63B22/08
Filed: 1997-08-27
Abstract: Cardiopulmonary interval training between a user high target heart rate and a user low target heart rate is obtained with an exercise apparatus (10, 60) by increasing the load (130) of the exercise apparatus (10, 60) at a first predetermined rate until either the maximum machine load is obtained (134) or the high target heart rate (132). When this event occurs, the load can then be maintained (136) at a fixed level for a predetermined time. Thereafter, the load is decreased (138) until the low target heart rate is obtained (140), or the user-set exercise duration expired. The heart rate of the user is monitored during the exercise. In the event that measurement of a valid heart signal is lost at any time (140), any increase or decrease of the load of the exercise apparatus is terminated (142) until a valid heart rate signal is reacquired. In the case when an exercise apparatus is a treadmill (10), the load can be varied by increasing or decreasing both the speed adjustment and the elevation adjustment of the treadmill. In the preferred embodiment, the speed is first adjusted until a user-set maximum speed is obtained and thereafter the elevation is adjusted in order to obtain the load variations toward or from the high and low target heart rates. The exercise may be repeated between the low and high target heart rates to provide cardiopulmonary interval training.

Title: Method and apparatus for load sharing on a wide area network
Inventor: RANGARAJAN SAMPATH
IPC: H04L29/06
Filed: 2000-02-17
Abstract: Client's (106-1 - 106-N, 107-1 - 107-M) on local area networks (102, 103) making requests to hot sites, which are connected on a wide area network (100) such as the Internet, are redirected through one of a possible plurality of different redirectors (101, 103) to one of a possible plurality of caching servers (S1, S2, S3), which each have responsibility for mapping one or more of the hot sites. Each request is probabilistically directed by one of the redirectors to one of the caching servers that map the requested hot site in accordance with weights that are determined for that redirector-hot site pair so as to minimize the average delay that all client requests across the network will encounter in making requests to all the cached hot sites. In order to determine the weights with which each redirector will redirect requests to the hot sites to the caching servers, statistics of access rates to each hot site are dynamically determined by each redirector in the network from the traffic flow and reported to a central management station (CMS) (115). Network delay is similarly measured by each redirector and reported to the CMS, and server delay is computed using a queuing model of each server. Using these parameters as inputs, a non-linear programming optimization problem is solved as a network flow problem in order to determine the weights for each redirector that will minimize the average delay. As the access rate statistics, as well as the network delay and server delay, dynamically change, the CMS, using the network flow algorithm, recalculates the weights and forwards them back to each redirector. In other embodiments, the redirector-logical item pair for which the redirector probabilistically directs client requests may be other than a hot site identity. For example, the logical items can be groups of clients or groups of documents, and the servers to which requests are forwarded can be web servers or caching servers.
