Title: Onboard diagnostic misfire detection monitor for internal combustion engines
Inventor: BIDNER DAVID KARL
IPC: F02D41/22
Filed: 2001-04-20
Abstract: A misfire monitoring method and system employ an indicated mean effective pressure (IMEP) parameter for misfire monitoring of an internal combustion engine of a vehicle. The method and system include determining displacement and torque of the engine. An indicated mean effective pressure (IMEP) parameter is then calculated for the engine. The indicated mean effective pressure (IMEP) parameter is engine torque divided by engine displacement. A misfire monitor monitors the indicated mean effective pressure (IMEP) parameter to detect misfire. The method and system include determining maximum indicated mean effective pressure (IMEP_MAX) parameter for the engine. A normalised indicated mean effective pressure (IMEP_LOAD) parameter for the engine is then calculated. The normalised indicated mean effective pressure (IMEP_LOAD) parameter is the indicated mean effective pressure (IMEP) parameter divided by the maximum indicated mean effective pressure (IMEP_MAX) parameter. Monitoring the indicated mean effective pressure (IMEP) parameter to detect misfire includes monitoring the normalised indicated mean effective pressure (IMEP_LOAD) parameter to detect misfire.

Title: Metering device having shuttle and spool valve
Inventor: PENN LAURENCE RICHARD
IPC: G01F11/02
Filed: 2001-07-09
Abstract: A metering device has a chamber 1 with a shuttle 6 therein, and a valve 40 adapted to control the flow of fluid to an end of the chamber 1, causing the shuttle 6 to move axially and displace fluid from the opposite end. Fluid is then subsequently supplied to the other side of the shuttle 6, causing it to move back to its initial position thus dispensing liquid from the other side. The valve 40 which controls the flow of fluid to each side of the shuttle is a spool valve, which can be moved from a first position where it forms a flow path between the inlet duct 25 and a first end 9 of the chamber and a second end 8 of the chamber and an outlet duct 27, to a second position where it forms a flow path between the inlet duct 25 and the second end of the chamber 8, and the first end of the chamber 9 and the outlet duct 28. A modification of the device (see figure 6) may be used to dispense two different products from either side of the shuttle, such as two components of an adhesive. A solvent may be present to contact the shuttle and avoid reaction between the two products.

Title: Pulse mid-point detector
Inventor: ARKAS EVANGELOS
IPC: H03K5/1532
Filed: 2001-08-02
Abstract: A pulse detector comprises a peak detector portion 100 and a trough detector potion 200. The two portions are identical except that the trough detection portion contains an inverter 210. An edge detection means is provided in each portion for detecting the leading and trailing edges of an input pulse and determining the pulse duration. A divider 170 produces a timing signal that represents the mid point of the input pulse and this is combined with a buffered copy of the input pulse in an AND gate 160. This produces an output signal at terminal 191 that is high only at the mid-point of each peak in the input pulse train. Similarly, the trough detector 200 has an AND gate 260 that produces a signal at terminal 192 that is high only at the mid-point of each trough of the input pulse train. Alternatively, the outputs of the AND gates 160, 260 may be combined in an XOR gate 410. The circuit may be used to determine the pulse centre to pulse centre time of e.g. a clock.

Title: A method of selectively storing images
Inventor: CHEATLE STEPHEN PHILIP
IPC: H04N5/781
Filed: 2002-01-07
Abstract: A camera 1 comprises first and second camera systems 3, 5. The first camera system 3 is a high resolution camera which captures images (so-called 'key frames') at a relatively low rate, whilst the second camera system 5 is a low resolution camera which captures images (so-called 'video frames') at a higher rate. Accordingly, a plurality of video frames are captured between each key frame. An application program is provided, either in a PC 13 to which the frames are downloaded, or in the camera 1 itself. The main purpose of the application program is to decide which of the captured frames should be stored, and which should be discarded (i.e. by a deletion or replacement operation) thereby freeing-up memory. This is performed by means of the application program performing an analysis of the image content in the frames, assigning a quality factor to the image content based on the composition quality of the image content, and updating memory to remove frames which have a quality factor indicating a lower composition quality than a subsequently captured frame. Thus, only those frames having 'interesting' content will be saved, and those frames which are poor in terms of their content or composition will not occupy memory if a better frame is identified.

Title: Electrically controlling multiple downhole devices
Inventor: MCDANIEL JEFFERY LEE
IPC: E21B47/12
Filed: 2002-01-25
Abstract: A production well control system 10 for electrically controlling multiple downhole devices (41, figure 2) individually or as a group comprises a surface control unit 12, a downhole control module 30 and multiple interface units 40, 50 etc. The operator inputs a command or request to the surface control unit which is passed to a power and communication system 14. The power and communication system generates a command signal of sufficiently high voltage to be sent downhole to the control module 30 which interprets and reformats the signal. The control module is connected to the multiple interface units, each of which is associated with a valve 41. Each interface unit is programmed to respond to a certain signal, energising its particular valve and transmitting data back to the control module 30. Alternatively, the valves are automatically actuated by the sensing of a downhole parameter such as temperature or pressure.

Title: Free rotation coupling for brake actuator
Inventor: HEINKEL HANS-MARTIN
IPC: F16D65/18
Filed: 2002-03-14
Abstract: A vehicle brake 12 actuation device comprises electro-motor 14 driving toothed wheel step down gearing 18 and a nut 32 and spindle 34 rotation to translation actuator via a claw coupling 16 The coupling has circular parallel discs 38, 40 with claws 42, 44 on the peripheries of their facing sides. The discs have a free rotation angle of almost 180{ in both directions of rotation before the claws abut to define the free rotational angle. When the coupling is idle spring 50 positions the discs to ensure free rotation on motor start. The electromotor starts smoothly over the free rotational angle until the claws abut. Motor inertia gained is used to overcome initial breakaway torque of gearing mechanisms to actuate the brake. Removes the need for oversized motors to handle breakaway torque. The motor may be initially turned opposite to its running direction to ensure maximum free rotation.
