Inventor: MULLIGAN DAVID NEAL
IPC: F02B43/04
Filed: 1995-05-03
Abstract: A hydrogen and natural gas fuel mixture (16) for internal combustion engines is provided for vehicle engines such as those used in standard production engines (10) for automobiles, trains, and lawn mowers.  The gaseous fuel (16) for operating vehicle combustion engines (10) includes approximately 21 to 50 % Hydrogen and the rest natural gas constituents such as combinations of Methane, Carbon Dioxide, Nitrogen, Ethane, Propane, Iso-Butane, N-Butane, Ipso-Pentane, N-Pentane and Hexans Plus. A fuel mixture of approximately 28 to 36 percent Hydrogen and an air fuel equivalence ratio of approximately 0.625 is an extreme lean burn condition that yields hydrocarbon emission levels of less than approximately 104 ppm (0.84 gm/hp hr.). Current internal combustion engines that are in mass production can take this alternative fuel without any substantial modificatrons to their systems. This alternative fuel is lean burning and emits emissions that are below current legal standards. The novel fuel mixture can be used in internal combustion engines for automobiles, lawn mowers and trains. A control system (14) for allowing the internal combustion engines (10) to operate at extreme lean burn conditions is also provided for use with both a carburetor and fuel injection system.

Inventor: COX DENNIS
IPC: A61B10/06
Filed: 1995-11-08
Abstract: Biopsy forceps (10), especially for endoscopic procedures, which enable tissue samples to be cut and retrieved, and which can coagulate the incision if necessary, while still at the situs of the excision. An electrically conductive control wire (14) is conductively connected to the jaws (24, 25) and spear (35) of the forceps (10). Should coagulation be required, a high frequency burst of electrical energy is applied to the control wire (14) and, thus, to the jaws (24, 25) and spear (35). The patient (45) is also connected into the circuit, usually through a metal plate (44) pressed against the patient's skin. The resulting heat coagulates the tissue which is in contact with the jaws (24, 25) and the spear (35).

Title: Process, sender and receiver for transmitting and selecting local radio programs in a common-wave broadcasting network
Inventor: ZUMKELLER MARKUS
IPC: H04B1/04
Filed: 1995-07-13
Abstract: The common-wave broadcasting of radio programs is known in the art. Common-wave operation of radio transmitters allows the available transmission band width to be particularly well utilized, for example for national scale common-wave broadcasts. A new process now allows a stereo transmission channel to be divided into two mono transmission channels during radio broadcasts and to broadcast certain programs only through particular transmitters. Information concerning the division of the stereo transmission channel into two mono transmission channels is further broadcast over the entire common-wave transmission network. This information causes receivers tuned to this transmission channel to automatically switch to mono evaluation of the reception signal. On a regional level, information may also be broadcast concerning which of both mono transmission channels may be received. Alternatively, the receiver or user himself may select the mono transmission channel he wishes to receive. This process may be implemented with all common-wave broadcasting modes.

Inventor: ERIKSEN PAUL
IPC: H01L31/0203
Filed: 1995-10-19
Abstract: In manufacturing an encapsulated optocomponent, the optocomponent is embedded in a plastics material. The optocomponent has guide grooves on one of its surfaces in which guide pins are to extend so that the encapsulated optocomponent will obtain an optical interface of standard type. For the encapsulating operation guide-pins are placed in a mould cavity in a mould half and the optocomponent is placed in the cavity in the mould, so that the guide pins are engaged in the guide grooves and are accurately inserted therein. To achieve this effect, a resilient or elastic force such as from plunger is applied to the other side of the optocomponent, so that it is pressed with some force against the guide pins. The cavity in the mould is then closed by placing a second mould half on top thereof after which the encapsulating material can be introduced in the closed cavity in the mould. The elastic force can also be obtained directly from a leadframe, to which the optocomponent is attached for electrical connection, or from a small elastic part, placed in, the cavity in the mould, this part then remaining in the capsule.
Patent CA-2204953-A1 (CA)
Inventor: KNODEL BRYAN D
IPC: A61B17/32
Filed: 1997-05-09
Abstract: An articulating surgical instrument with an articulation transmission assembly for remotely articulating the end effector of the instrument is disclosed. The instrument includes a body with a housing mounted on the instrument, oscillating and rotating members, and an actuator rotatably mounted on the housing and secured to the rotating member. The oscillating member is seated rotationally stationary within the housing. The rotating member fits into the oscillating member, and has a drive shaft extending into the body for translating rotation from the rotating member into reciprocation of an elongated transmission rod attached to the drive shaft.  First and second sets of unloading teeth are displayed on the oscillating member and actuator, respectively. First and second locking teeth are displayed on the oscillating and rotating members, respectively. The assembly provides ratcheting rotation for precisely positioning the end effector in discrete positions. Since the assembly has a ratcheting mechanism, it is "fail safe" when a force is applied to the end effector to prevent the component parts of the assembly from breaking. In the preferred embodiment, the frictional forces between the unloading teeth are less than those between the locking teeth. Therefore, the force which the surgeon is required to apply to the actuator of the assembly to cause articulation of the end effector is less than that which would be necessary to articulate the end effector when a force is applied on the end effector itself. The instrument may be used for endoscopic as well as conventional open surgical procedures.

Title: Method and apparatus for encoding a video signal using feature point based motion estimation
Inventor: JUNG HAE MOOK
IPC: H04N19/53
Filed: 1995-05-06
Abstract: An apparatus for encoding a digital video signal (217) to reduce a transmission rate of the digital video signal, which comprises a feature point based motion compensation circuit (150) for selecting a set of feature points from the reconstructed reference frame to detect a set of motion vectors between a current frame and an original reference frame corresponding to the set of feature points by using a feature point based motion estimation, and for generating a second predicted frame based on the set of motion vectors and the reconstructed reference frame. The feature point based motion estimation employs a convergence process in which a displacement of each of the feature points are given to a motion vector thereof and the six triangles of each of the hexagon are affine-transformed independently using the displacements of their vertex feature points. If the displacement provides a better peak signal to noise ratio (PSNR), the motion vector of the subject feature point is sequentially updated. Therefore, the inventive convergence process is very efficient in the matching process to determine the predicted image as close as possible to the original image having zooming, rotation or scaling of objects.

Title: Apparatus and method for discriminating flow of blood in a cardiovascular system
Inventor: ROSBOROUGH JOHN P
IPC: A61N1/39
Filed: 1996-05-31
Abstract: An implantable cardiac stimulator includes means for delivering a first electrical shock via implantable stimulating electrodes at a time when there is substantially no flow of blood, as determined by conventional fibrillation detection means. At least one of the stimulating electrodes is disposed in a blood flow path of the cardiovascular system. The first shock is preferably of insufficient energy level to cause defibrillation. A potential is measured as a function of time between the blood-contacting electrode and a reference electrode following delivery of the first shock to obtain a first potential equilibration function under no-flow conditions. A second therapeutic electrical shock, preferably of sufficient energy level to effect defibrillation, is delivered via the stimulating electrodes. A second potential equilibration function is measured following delivery of the second shock. The first and second potential equilibration functions are compared, and if the two functions are sufficiently different in morphology, it is determined that blood is flowing.
