The invention relates to a networked control system including comprising a resource limited device (102) and an assigned proxy device (104). The resource limited device (102) comprises a device logic (122) for providing a change notification message to the assigned proxy device (104) on a change of a device state of the resource limited device, wherein each device state of the resource limited device (102) is defined by a corresponding state variable and wherein the change notification message comprises a state variable corresponding to an actual device state of there source limited device (102). The assigned proxy device (104) comprises means (142) for receiving a change notification message from an assigned resource limited device (102), wherein the change notification message comprises a state variable which defines an actual device state of the resource limited device and means (144) for distributing a state variable change notification, comprising the state variable which defines the actual device state of the resource limited device, within the networked control system according to requirements of a control application (162) of the networked control system.

A soil densification system and method is disclosed. The presently disclosed soil densification system includes an air delivery probe or pipe that can be driven or otherwise installed into a soil mass. An inlet of the air delivery probe is supplied by an air compressor and an air storage tank, which are used for the rapid delivery of air impulses or bursts into the air delivery probe, whereas the air impulses or bursts are expelled out of an outlet of the air delivery probe and into the soil mass. The method of using the presently disclosed soil densification system includes the steps of inserting the end of the air delivery probe into the soil mass to any desired depth and then releasing an impulse or burst of air into the soil mass, thereby forming a densified region in the soil mass via the forces of the air impulse.

PROBLEM TO BE SOLVED: To provide an inexpensive double vacuum vessel for a vehicle with simple structure. SOLUTION: A double vacuum vessel 20 for a vehicle has an inner vessel 21 including a diaphragm part 29 which is expanded when pressure of cooling water taken into the inner vessel 21 is high, and restored to its original state when the cooling water pressure becomes low. The diaphragm part 28 has a projection part 29, and an outer vessel 22 has a recess part 31 to which the projection part 29 is fitted. The diaphragm part is expanded as the cooling water pressure becomes high, and the projection part is fitted to the recess part to mechanically connect the inner vessel to the outer vessel. Therefore, there is no fear that the inner vessel is excessively vibrated even if it receives vibrations during travelling. The double vacuum vessel 20 for a vehicle has simple structure and is inexpensive. COPYRIGHT: (C)2008,JPO&INPIT

In a heat accumulator for a vehicle having a double tank structure comprised of an outer tank and an inner tank, which define therebetween an evacuated space, each of the outer and inner tanks has an opening. The opening of the outer tank and the opening of the inner tank are welded to each other over the entire peripheries thereof. A means for restricting vibration of the inner tank is provided in the accumulator. At least when the vehicle is stopped, the outer tank and the inner tank are not in contact with each other at any portion other than the welded portion.

PROBLEM TO BE SOLVED: To provide a vehicular heat accumulator having heat accumulating performance and improved in vibrational proof. SOLUTION: In the vehicular heat accumulator having a double structure of an outside tank and an inside tank and keeping a space between the outside tank and the inside tank vacuum, the outside tank and the inside tank respectively have openings on bottom surfaces, and the opening of the outside tank and the opening of the inside tank are joined with each other at the whole of their periphery. On the bottom surface of the outside tank, a part having lower stiffness than other parts is provided. COPYRIGHT: (C)2004,JPO
