Title: Massage device
Inventor: CZIRIAK ATTILA
IPC: A61H7/00
Filed: 1996-12-16
Abstract: A massaging device is driven by a water wheel and having a plurality of fingers spread in concentric rings about an arched cover.  The fingers are supported in and actuated by a rotating camming platform including a series of concentric camming surfaces with curved bases and irregularly shaped annular sidewalls.  The fingers are reciprocated along their vertical axes to create a wave-like motion relative to the cover.  Concurrently, the fingers are actuated to pivot about a central transverse axis defined by pin members located on opposite sides of the fingers.  When driven by a water wheel, the device contains a water channel along its base, which channel extends to a water chamber containing the water wheel. The wheel is turned by water flow through the chamber thereby rotating the camming platform to which it is coupled by way of gears.
Patent CA-2194105-A1 (CA)
Title: Control system with collection chamber
Inventor: THOMPSON GRANT R
IPC: E21B34/10
Filed: 1996-12-30
Abstract: A control system for the operation of the subsurface safety valve is dis-closed. The control system uses a pressurized gas chamber, as well as a shuttle valve which connects to the main fluid pressure supply from the surface. The shuttle valve is connected to the gaseous chamber as well as to a barrier piston. As a result of the arrangement, leakages between the downstream side of the operating piston and the shuttle valve result in a reestablishment of the pressure balance on the operating system which allows the subsurface safety valve to close. Additionally, in the event of loss of gaseous pressure, the same pressure-balancing effect occurs on the operating piston, which allows the subsurface safety valve to go to a closed position. The configuration of the control system, which includesa gaseous chamber, allows for disconnection of the hydraulic fluid supply beforethe predetermined depth is reached to facilitate the connection of a tubing hanger.

Title: Athletic shoe
Inventor: BRISSETT IAN
IPC: A43B13/18
Filed: 1997-05-16
Abstract: My invention involves the inplantation of a set of compression springs on the inside and base of an athletic shoe, in the front area of the shoe. The purpose of this invention is to try and help athletes increase their athletic ability and potential.     The invention works like this: The athlete wears the specially made athletic shoes for any particular sport, whether it be track and field, basket-ball, volley-ball, or any other sport involving running and jumping.  I'll use basket-ball as an example; the athlete will be able to increase his/her jumping potential.  When an athlete jumps, all of the force and weight is focused in the front half of the foot, ( from the ball to the toes ).  The springs in the athletes shoes are located in this area.  The force and weight of the athlete helps compress the springs just enough to not fully compress and as the athlete releases, he/she gets that extra leverage from the springs.  As the athlete lands, the weight and force of landing is absorbed through cushioned layers in this area of the shoes.  The springs are all the same height, 7/8 of an inch, and are all the same diameter, 11/16 of an inch, except for one which is 1 inch and 1/8 in diameter.  The springs are made of stainless steel and are open wound helical springs.  They are cylindrical in shape and have squared and ground ends coiled left hand.  Force of the springs equals the weight class of the athlete within 10 - 20 lbs., ( example:  Force equals 70 lbs. at 1 and 3/4 inches compressed height ( 1 and 1/2 inches deflection from free length, solid height equals 1 and 5/8 inches maximum with ends closed and ground. ).  Stress equals 700-1000 psi.  All the springs will be strategically placed on a flexable, hard piece of plastic taking the shape of the front of the shoe.  The springs will be held down by a set of screws, (4), one on each side and top to bottom of the circumfrence of the springs.  An inner ring of equal width will be placed inside the springs before screwing the springs down, so that the screws will be equally leveled in place.  A thin layer of hard plastic will be placed over top of the springs before the layer of foam cushion and the insole.

Title: Multicolor organic light emitting devices
Inventor: MCCARTY DENNIS M
IPC: H01L27/15
Filed: 1995-12-06
Abstract: A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds.  The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure. The devices are configured as stacked to provide a staircase profile whereby each device is separated from the other by a thin transparent conductive contact layer to enable light emanating from each of the devices to pass through the semitransparent contacts and through the lower device structures while further enabling each of the devices to receive a selective bias.

Title: System and method for automatic registration notification for over-the-air activation
Inventor: CHATTERJEE ARUN K
IPC: H04W8/26
Filed: 1997-06-24
Abstract: A method and system automatically activates a mobile station in a wireless communications network. The system includes an over the air activation function (OTAF) processor in the network that initiates an activation process in response to receiving a registration message from a mobile switching center serving the mobile station requesting the activation. Each mobile station has a unit of information stored into it at the time of its manufacture to enable it to request over the air activation. That unit of information is either the network routing address of the OTAF processor, or alternately, it is a value that is translatable into that address, either an OTAF ID number that is the same value for every mobile station or it is a sequentially serialized dummy value for the mobile identification number (a dummy MIN). When the mobile station is turned on for the first time in the network, it requests activation over the air by transmitting to the local mobile switching center a registration order. The registration order will include one of the three alternative forms of the information unit described above, either the routing address of the OTAF processor, or the OTAF ID number, or a dummy MIN.
