Abstract: A thermally regulatable, pulsating cushioning device having a deformable outer membrane being adapted to sealably receive a liquid material therein; a foam core being encased within and in intimate contact with, but not bonded to the flexible, deformable outer membrane wherein the foam core has a dimension substantially coincident with the outer membrane; a liquid material, sealably contained within the flexible, deformable outer membrane and saturating the foam core, with the liquid material being at least partially circulatable throughout the foam core, wherein the cooperation of the saturated foam core and the sealable flexible membrane provide a uniform, thermally regulatable medium and structural support such that the pulsating cushioning device is readily, uniformly deformable when a load is applied thereto; a means for directly pulsating the liquid within the flexible, deformable outer membrane, causing the device to undulate or vibrate; and a thermal regulator cooperating with the liquid material to e

Abstract: An interlink system for conveying security quotations and other related data to remote locations by means of satellite down link and preferably providing a satellite up link for remote users to place authenticated orders for securities. The satellite uplink/downlink is preferably by synchronous satellite. The hand held portable receiver/transmitter for receiving a plurality of said quotations and broadcasting data representing each of said orders with appropriate encrypting has storage capacity individually storing the received data representing each of said quotations. A display on the handheld unit coupled to the storage allows the user to display individually selecting data representing any one of the received quotations. The device can also store and transmit an encrypted, authenticated order to transact securities by means of the handheld unit.
