  • Patent number: 9786033
    Abstract: A method for displaying sensor readings in a measurement instrument having an array of display elements initially divides the range of interest of the sensor reading into a plurality of consecutive sub-ranges and determines a scaling function for displaying sensor readings for each sub-range. For each sensor reading, the appropriate sub-range is determined into which the sensor reading falls (where N is the number of this sub-range). The scaling function for the Nth sub-range is applied to display the sensor reading using N consecutive display elements. Optionally, the system may include a visual or audible indicator for the use when the display rolls from one sub-range to another. The display may also include feature indicating the peak sensor reading encountered.

  • Patent number: 7379601
    Abstract: Complex multidimensional datasets generated by digital imaging spectroscopy can be organized and analyzed by applying software and computer-based methods comprising sorting algorithms. Combinations of these algorithms to images and graphical data, allow pixels or features to be rapidly and efficiently classified into meaningful groups according to defined criteria. Multiple rounds of pixel or feature selection may be performed based on independent sorting criteria. In one embodiment sorting by spectral criteria (e.g., intensity at a given wavelength) is combined with sorting by temporal criteria (e.g., absorbance at a given time) to identify microcolonies of recombinant organisms harboring mutated genes encoding enzymes having desirable kinetic attributes and substrate specificity. Restriction of the set of pixels analyzed in a subsequent sort based on criteria applied in an earlier sort (“sort and lock” analyses) minimize computational and storage resources.

  • Patent number: 6911959
    Abstract: The present invention provides a bar indicator that minimizes the burden placed on the microcontroller. A horizontal bar indicator is generated that requires very little microcontroller firmware overhead, allowing a less powerful microcontroller to be used in the application. The reduced firmware requirement translates into smaller microcontroller firmware ROM requirements, thus enabling a lower cost system to be realized. The bar indicator uses a single byte written to a counter to represent the size of the bar. This byte written to the counter is readily available from the actual parameter value representing the size of the bar without significant additional calculation. The OSD video coming from the OSD logic is overridden with a pixel overwrite when the location of the bar indicator is located. The bar overwrites whatever is located at the position of the bar indicator. The pixel override occurs for a predetermined time.

  • Patent number: 5528255
    Abstract: A display control device for a level meter, including a BPF for performing a band-pass filtering of an audio signal to obtain a plurality of frequency components. The BPF obtains an average level of each frequency component of the audio signal. A variable resistor divides a power source voltage. An A/D converter converts the frequency components of the audio signal, the average level and the divided voltage into digital signals. A display controller displays the levels of the frequency components and the average levels thereof on an LCD. The display controller holds a peak value of one of the frequency components or the average levels thereof, and the peak hold time is determined on the basis of the divided voltage. The peak hold time can be freely changed depending on tastes and uses of users.

  • Patent number: 5486843
    Abstract: A signal level indicator (204, 304) displays the magnitude of an input signal (421) by illuminating each of a number of five LEDs (314-318, 414-418) for an individual period of time. The number of LEDs to be illuminated and the individual period of time that each is to be illuminated varies with the magnitude of the input signal (421).

  • Patent number: 5376917
    Abstract: A vehicular display apparatus having a light transmitting display section activated by means of a high-luminance light source, and a high-luminance, self-glowing light emitting display section. The apparatus selectively operates one of these display sections which is selected by a selector switch, so that the selected display section can be visually perceived from the driver's seat side through a meter glass which has a low light transmittance characteristic, thereby making it possible to select a display form which can be observed by the driver with a high degree of contrast between the display section and the background, and which is suited to his preference.

  • Patent number: 5373308
    Abstract: A method and apparatus for displaying a bar image in two colors on a screen of a cathode ray tube are disclosed. The device includes a first memory for storing the information to be displayed, including the first color, and a second memory for storing the screen addresses where the images are to be displayed in a second color. It also includes a microprocessor for selecting information from the first memory to be displayed at specific addresses on the screen. When the address for display is the same as one stored in the second memory, the microprocessor causes information to be displayed in the second color instead of the first color.

  • Patent number: 5369416
    Abstract: A bargraph with a single set of light emitting diode (LED) segments creates a display showing a parameter level by the number of segments illuminated and a separate condition by the color of all illuminated segments. For example, an input parameter in a normal data range results in all segments below and at the data level being illuminated in a first color. Satisfaction of a first set point condition by that or another input results in all segments below and at the data level being illuminated, but all illuminated in a second color; and satisfaction of a second set point condition results in all segments below and at the data level being illuminated, but all illuminated in a third color. All of the segments below the data level change color with passage of the set point. The bargraph combines present data value, alarm set points, and indication of set point exceedance in a single bargraph through use of multi-color activated segments.

  • Patent number: 5287287
    Abstract: A device for displaying power consumption rates includes a register for storing and displaying the cost of a unit of power, e.g., the cost per kilowatt hour as assessed by the local power company. A first display indicates the cost of power consumed over a first time period (such as an hour) based upon the then-existing instantaneous rate of power use. A second display indicates the cost of power projected to be consumed over a second time period such as a day, assuming that the then-existing instantaneous rate of power usage is maintained. A third display indicates the cost of power projected to be consumed over a third time period such as 30 days while fourth, fifth and sixth displays provide the instantaneous rate at which power is being consumed as well as totalized actual costs over two different time periods. A register is equipped with structure for adjustment whereby the cost stored in the register of a unit of power may be changed.

  • Patent number: 5247864
    Abstract: A display apparatus for an electronic musical instrument according to the first invention has a display section including multiple indicators provided in association with multiple tone parts, each indicator having multiple LEDs, a register section for reading out lighting time information from a memory which has lighting time information of the LEDs stored, and a counter section for performing a countdown operation in a predetermined time interval with the lighting time information in the register section as an initial value. When generation of a musical tone is instructed, the LEDs of the indicators which are associated with tone parts of the musical tone and whose quantity corresponds to volume information of the musical tone, are lit. When a count value of the counter section reaches zero, one of the LEDs is turned off or on, and the lighting time information in the register section is reset in the counter section to re-start a countdown operation.
