Patent EP-0479033-A2 (EP)
Inventor: EGE GUIDO DIPL-CHEM
IPC: G01N27/48
Filed: 1991-09-17
Abstract: To determine a concentration of gases which can be converted electrochemically (by oxidation or reduction) (CO2, CO, H2S, hydrocarbons, NOx, SO2 and the like) in any desired fluid, the test gas (analyte) is adsorbed for a specified time (tads) by applying a constant potential (E2) to the working electrode and a resultant current/time function, which correlates with the concentration of test gas, is evaluated against a background current curve unaffected by the test gas from a subsequent, ramp-type potential rise (potential sweep) (LPSV method). It is proposed to arrange for the first measurement cycle to be followed by a reference cycle for determining the pattern of the background current curve, which is a further ramp-type potential rise immediately following the measurement cycle after the potential has dropped to the initial constant potential (E2) applied to the working electrode, but with negligible prior adsorption of the analyte at the working electrode, this second measurement being equivalent to a measurement with the test gas (analyte) absent. <IMAGE>

Abstract: A gas lighter with a safety device has a lock member which is able to linearly move between a locking position where it prevents depression of an ignition lever and a releasing position where it allows depression of the ignition lever and is urged to the locking position. A holding member hold the lock member in the releasing position in response to movement of the lock member to the releasing position, and a releasing member releases the lock member from the holding member in response to depression of the ignition lever, thereby permitting the lock member to move away from the releasing position. A temporary holding member temporarily holds the lock member in the releasing position or the vicinity thereof until the ignition lever returns to the original position.

Abstract: A time switch device (31) for a sequence of control signals (39) to be transmitted as a function of time, for example for the time-dependent variation of command variables in control engineering or for directly switching operating or checking devices on or off as a function of time, is intended to be capable of easier control by an operator while being designed for greater ease of production. For these purposes, the ability for the time-locking circuit to be influenced manually by the user or for it to be decoded by interrogation is completely abandoned, and instead the time switch device (31) is fitted from the outset in the factory with a lithium battery (32), which is typically designed with a lifetime of at least ten years, and taken into operation such that it cannot be switched off. This time switch device (31) therefore already runs correctly when commissioned without the need for the operator to intervene in its functioning. All that remains necessary manually is to select between a number of prescribed switchover time sequences by means of a program changeover switch (37), for which purpose there is also no need for any user guidance on the display, which means that it is also possible to abandon a (time) display, including the functionally critical multiple connections to display/control circuits, which are complicated in terms of circuitry, and likewise to abandon the setting switch wiring that is otherwise required for intervention in the time-dependent switching sequence. <IMAGE>

Abstract: A collapsible roadway impact attenuator (10, 100) includes an array of spaced parallel support elements (18, 116) arranged to move axially when the attenuator (10, 100) is struck by impacting vehicle. Elastomeric energy absorbing sheets (50, 114) are rigidly secured between adjacent support elements (18, 116) so as to extend axially and horizontally. When the attenuator (10, 100) is struck axially by a vehicle, the support elements (18, 116) move towards one another and the energy absorbing sheets (50, 114) form at least three inflections (58a, 58b, 58c, 118), thereby enhancing energy absorbing efficiency of the attenuator (10, 100). Tethers (112) can be mounted between overlying elastomeric sheets (114) to increase the number of inflections (118) and the energy efficiency of the attenuator (110).

Abstract: In a method of analyzing a lighting environment, the lighting environment is initially divided into a plurality of blocks (30) so that all surfaces defining said lighting environment may be divided into a plurality of surface patches. The surface patch (11) that radiates the most light energy is then searched. If the quantity of light radiated from this surface patch (11) exceeds a given value, the quantity of light radiated from this surface patch (11) which arrives at each of said plurality of surface patches is computed. Thereafter, the surface patch that radiates the next most light energy is searched, and the quantity of light radiated from this surface patch which arrives at each surface patch is computed. In this way, the total quantity of light received by each surface patch is obtained. In this method, mirror reflection is taken into account.

Abstract: Drivers for field-controlled switches are powered and switched on and off by the same combined command and power signal which consists of a command signal modulated by a clock signal forming a command envelope including a train of clock pulses. Presently, the first clock pulse in the train is used to restore power to the driver lost through leakage from the driver during the switch signal low state. The invention prevents power from being lost by refreshing power during the PWM low state, such that the command high state pulses need not be used for restoring power. Power and a command to a field-controlled driver is provided by a combined command power signal consisting in the on-state of groups of clock pulses, the groups being a function of a the switch signal pulse width, and in the off-state of the absence of the group of clock pulses. During the off-state of the driver, power is refreshed. In addition, the dead time occurs within the driver circuit, while the driver is being switched on by integrating the clock pulses.

Abstract: An original image is divided into a plurality of pixel blocks each consisting of a plurality of pixels. A density histogram is obtained for each pixel block in an electric circuit. Respective pixel blocks are analyzed to find adjacent pixel blocks which are uniform and continuous in density. If the pixel blocks thus found are continuous in density with the reference pixel blocks located at the corner of the original image, the pixel blocks are regarded as those representing the background portion of the original image. The numbers of pixels in the density histogram is corrected for each background pixel block, and highlight and shadow points for determining a gradation curve is determined. The gradation curve is set in a signal-converter to convert an image signal representative of the original image.

Abstract: A pagewidth thermal ink jet printhead for an ink jet printer is disclosed. The printhead is of the type assembled from fully functional roofshooter type printhead subunits (26A) fixedly mounted on the surface of one side (67) of a structural bar (62). A passageway (64) is formed adjacent the bar side surface containing the printhead subunits with openings (65) provided between the passageway and the ink inlets of the printhead subunits, mounted thereon so that ink supplied to the passageway in the bar will maintain the individual subunits full of ink. The size of the printing zone for color printing is minimized because the roofshooter printhead subunits are mounted on one edge of the structural bar and may be stacked one on top of the other without need to provide space for the printhead subunits and/or ink supply lines. In addition, the structural bar thickness (T) enables the bar to be massive enough to prevent warping because of printhead operating temperatures.

Abstract: A chroma key generation method and apparatus are provided (for both composite and component video) in which an operator selects (50,51a,51b,53,60) a reference portion of a color television image to identify it as the background of the image, and a strobe signal is then generated (50) whenever the video data that is presently passing through the keyer is within the reference portion of the color video image. This strobe causes the video data corresponding to that portion of the image to be stored (34,36,38). A microprocessor (80) then determines attributes of the video in the reference portion of the color image from the stored video data, these attributes including a reference hue, α. The image hue ϑ at each pixel in the color image is correlated (4) with the reference hue α to produce a correlation signal that has a first range of values for points of the color image at which the image hue matches the reference hue and a second range of values for points of the color image at which the image hue does not match the reference hue. After further processing (6,8,10, 26,27a,27b,48,49, 22,24,46,25b,28), this correlation signal becomes a chroma key signal. The attributes of the video in the reference portion of the image are employed via the microprocessor (80) to process the video signal and associated chroma key signal in several ways, including background suppression matte generation (40,42,44,14,12,16), shadow clip level input to the shadow comparison circuitry (22,24,46,25b,28) and the gain of the key signal variable gain comparator (26,27a,49,48,26).
