An active suspension for a driver seat of a bus or a heavy vehicle which comprises an electric actuator allowing the exertion of the force between the floor of the vehicle and the bottom of the seat. The adjustment of the height of the seat is accomplished by an electric actuator or by an independent mechanical system. A controller generates a control force calculated from measurements obtained by sensors located at different locations on the suspension. Forces exerted by the electric actuator can be relieved by passive element placed in parallel which cannot assume by themselves the role of a suspension for a given application.

A method and system for automatically adjusting the operating parameters of a rate-adaptive cardiac pacemaker in which maximum exertion levels attained by the patient are measured at periodic intervals and stored in order to compute or update a maximum exercise capacity. The slope of the rate-response curve is then adjusted to map an exertion level corresponding to the updated maximum exercise capacity to a maximum allowable pacing rate. In accordance with the invention, a maximum exercise capacity is determined by cross-checking periodic maximum exertion level sensor values with a motion-level sensor value.

Devices and methods are disclosed for achieving hemostasis in patients who have received skin-penetrating wounds to the periphery, including the head, arms, and legs. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery, or military setting. The devices utilize fluid impermeable barriers surrounded by exterior dams and pressure to achieve tamponade and hemostasis, primarily by exertion of force to hold the dams against the skin surrounding a wound. The devices are capable of serving as carriers for thrombogenic, antimicrobial or antipathogenic agents. The devices do not require the use of adhesives to work as they are attached to the patient using mechanical locking devices. Peripheral haemostatic packing devices include optional adhesive hemostatic barriers to attach at least a portion of the device to the skin or to assist with initial coupling of a hold-down strap to another strap using a more secure mechanical lock. The peripheral hemostatic packing system does not completely surround the extremity having the wound and therefore do not cause a tourniquet effect. The peripheral hemostatic packing system preferably is held against the skin surrounding a wound by a force that is generally unidirectional and substantially perpendicular to the plane in which the skin of the wound resides.

In an embodiment, the invention includes a method of controlling a cardiac rhythm management device in response to exertion of a patient, the method including sensing the patient's pulmonary function at a first time t₁ and at a second time t₂; calculating a rate of change of the pulmonary function between time t₁ and time t₂; sensing the patient's cardiac function at time t₃ and t₄; calculating a rate of change of the cardiac function between time t₃ and time t₄; and setting a desired pacing rate. Embodiments of the invention also include cardiac rhythm management devices.

The present invention provides for a variable stride exercise device having a variable size close curved striding path during use. The exercise device described and depicted herein utilizes various configurations of linkage assemblies, cam members, and other components, connected with a frame to allow a user to dynamically vary his stride path during exercise. An exercise device conforming to aspects of the present invention provides a foot path that adapts to the change in stride length rather than forcing the user into a fixed size path. A user's exertion level may have several components impacting the stride length provided by the machine, such as leg power, torso power, and (in embodiments with arm supports or exercise components) arm power. Other embodiments of the exercise device include a lockout device that selectively eliminates the variable stride features of the exercise device and allows the user to exercise in a stepping motion.

Exercise machines are networked together to provide a user with an indication of the user's performance level compared to the performance levels of other users. Simulated characters corresponding to the users are shown on one or more displays viewable by the users. The simulated characters have a primary movement that may differ in type from the primary movement used in achieving the exercise by the corresponding user. Further, the primary movement used to achieve exercise by one user may differ from the primary movement used to achieve exercise by another user. Exertion transducers provide signals that are used in calculating parameters such as speed and acceleration. Biometric data may be measured from the users during exertion and displayed or uploaded onto the network.
