DETAILED DESCRIPTION

Referring generally to the figures, various embodiments of a level tool are shown. In general, the levels discussed herein include audio and/or visual indicators. The audio and visual indicators are electronically triggered to indicate when the level is positioned at a specific angle such as vertical (i.e. plumb) or horizontal (i.e. level). The audio and/or visual indicators of the level embodiments discussed herein assist users in measuring levelness by clearly indicating when a specific state, such as level or plumb, has been reached. In some embodiments, the level includes light sources positioned to brightly illuminate the level vial, and in some such embodiments, the light sources are controlled based on a levelness signal received from an electronic position sensor.

Referring to FIG. 1, one embodiment of a level 10 having audio and/or visual indicators is shown. Level 10 includes a level body, shown as housing 12 (e.g. body, frame, structure, etc.). Plumb vial assemblies 14, level vial assembly 16, and audio indicator 18 are set in and are supported by housing 12 and are visible from the exterior of level 10. Internal electronics 19 are set in and are supported by the interior of housing 12 and, in specific embodiments, are not visible from the exterior of level 10.

In one embodiment, plumb vial assemblies 14 each have a vial surround 20, vial 22, and visual plumb indicators 26. Vial surround 20 contains and supports vial 22 within housing 12. Vial 22 is an analog indicator of levelness and is positioned to measure whether level 10 is vertical or plumb. In one embodiment, vial 22 is a spirit vial including a bubble that moves within the vial as the level position changes. Light sources, shown as visual plumb indicators 26, are generally positioned to direct light into vial 22, and in specific embodiments are located to direct light through both opposing end walls of a generally cylindrical shaped vial 22. In this arrangement, visual plumb indicators 26 are positioned to direct light in the direction of the longitudinal axis of vial 22. Various embodiments of level 10 having more or fewer plumb vial assemblies 14 are contemplated. In one embodiment level 10 includes no plumb vial assemblies 14.

In one embodiment, level indicator 16 has a support frame 28, a vial 30, and light sources, shown as visual level indicators 34. Support frame 28 contains and supports vial 30 within housing 12. Vial 30 is an analog indicator of levelness and is positioned to measure whether level 10 is vertical or horizontal. In one embodiment, vial 30 is a spirit vial including a bubble that moves within the vial as the level position changes. Visual level indicators 34 are generally positioned to direct light into vial 30, and in specific embodiments are located to direct light through both opposing end walls of a generally cylindrical shaped vial 30. In this arrangement, visual level indicators 34 are positioned to direct light in the direction of the longitudinal axis of vial 30. Various embodiments of level 10 having multiple level vial assemblies 16 are contemplated. Positioning visual indicators 26 and 34 such that light is directed into both end walls of vials 22 and 30, respectively, provides for bright, high quality illumination of vials 22 and 30.

Visual indicators 26 and visual indicators 34 are configured to illuminate vials 22 and 30 respectively when activated in response to a control signal. In one embodiment, the liquid within vial 22 and vial 30 contains an ultraviolet light activated optical brightener that enhances or increases the brightness of light leaving the illuminated vials 22 and 30. In various embodiments, visual indicators 26 and 34 are configured to generate light having a first color when the associated level vial indicates levelness and to generate light of a second color (different from the first color) when the associated level vial is not indicating levelness.

In one embodiment, visual indicators 26 and visual indicators 34 each include two pairs of light emitting elements, such as light emitting diodes (LEDs). A pair of LEDs is positioned at each end wall of the generally cylindrical vial 22 and vial 30 respectively. The different LEDs in each pair generate a unique and visually distinct color. For example, an LED pair may include one red LED and one green LED. In another embodiment, visual indicators 26 and visual indicators 34 are one single color LED. In other embodiments, visual indicators 26 and 34 may include various numbers of LEDs located outside of each end wall of vials 22 and 30, such as 1 LED, 3 LEDs, 4 LEDs, etc.

In one embodiment, audio indicator 18 includes a speaker 36 and a support frame 38. Support frame 38 contains and supports speaker 36 within housing 12. Audio indicator 18 is configured to produce an audio signal through speaker 36 in response to a control signal. In another embodiment, audio indicator 18 is omitted from level 10.

Referring now to FIG. 2, a schematic diagram of an electronic level indication system for a level including audio and visual indicators, such as system 41 is shown according to an exemplary embodiment. Internal electronics 19 include a controller 40 and an electronic position sensor, shown as a level/plumb sensor 42. Controller 40 and level/plumb sensor 42 are located inside housing 12. Level/plumb sensor 42 is electrically coupled to controller 40. Controller 40 is electrically coupled to visual plumb indicators 26, visual level indicators 34 and/or audio indicator 18. Internal electronics 19 also include a power supply configured to power controller 40, level/plumb sensor 42, visual plumb indicators 26, visual level indicators 34 and audio indicator 18. In various embodiments, the power supply includes one or more alkaline batteries, one or more rechargeable battery, such as lithium-ion batteries, solar cell, etc.

In one embodiment, level/plumb sensor 42 is an electronic component that detects the position of level 10 along its longitudinal axis relative to 100 percent horizontal (i.e. level) and/or 100 percent vertical (i.e. plumb). For example, sensor 42 generates a levelness signal when a base surface 23 is oriented in the horizontal direction, and when base surface 23 is oriented in the horizontal direction, the bubble of level vial 30 is located in the center of level vial 30. Level/plumb sensor 42 generates a signal representative of the position or orientation of level 10 and sends that signal to controller 40. In one embodiment, level/plumb sensor 42 generates a levelness/plumbness signal when level 10 is within a specific percentage of level or plumb, such as 99 percent. Level/plumb sensor 42 is calibrated to correspond to measurements of analog vials 22 and 30. Specifically, the signal generated by level/plumb sensor 42 will be a level signal when the bubble of vial 30 is level (e.g., the bubble is located in the center of vial 30) and a plumb signal when the bubble of vial 22 is plumb (e.g., the bubble is located in the center of vial 22). In one embodiment, level/plumb sensor 42 is an accelerometer. In another embodiment, multiple level/plumb sensors 42 are used for each different vial of level 10. As will be explained in detail below, one or more aspect of visual indicators and/or speaker 36 are controlled based on upon the levelness/plumbness signal from sensor 42.

In various embodiments, controller 40 is any electronic control device or circuit configured to control the various devices discussed herein. For example, control 40 may include microcontroller, microprocessor, ASIC, computer, FPGA, etc.). Controller 40 receives the signal generated by level/plumb sensor 42 and interprets or parses the signal to determine what if any control signal to generate and send to visual level indicators 34, audio indicator 18, and/or visual plumb indicators 26. In one embodiment, controller 40 is configured to control an aspect of light generated by one of the visual indicators to illuminate the associated level vial in response to the signal received from the electronic position sensor. In one embodiment, controller 40 is configured to control an aspect of sound generated by speaker 36 in response to the signal received from the electronic position sensor. In one embodiment, the aspect of light generated by the light source controlled by controller 40 is at least one of the activation of the light source, the color of light generated by the light source, the intensity of light generated by the light source and a pulse rate of light generated by the light source. In one embodiment, the aspect of sound generated by speaker 36 controlled by controller 40 is at least one of the activation of the speaker, the frequency of sound generated by the speaker, the volume of sound generated by the speaker source and a pulse rate of sound generated by the speaker. In one embodiment, controller 40 controls activation of visual level indicators 34, audio indicator 18, and visual plumb indicators 26 by opening and closing electrical and/or physical switches that selectably allow power to be sent to those components.

In one embodiment, controller 40 generates and sends control signals to visual level indicators 34, audio indicator 18, and/or visual plumb indicators 26 when level 10 is approximately level or plumb. In another embodiment, controller 40 generates and sends control signals to visual level indicators 34, audio indicator 18, and visual plumb indicators 26 continuously with the specific value of the signal determined by the value of the signal received from level/plumb sensor 42.

In various embodiments, visual level indicators 34 and/or visual plumb indicators 26 include a first element generating light having a first color and a second element generating light having a second color different than the first color. In one such embodiments, controller 40, based on the signal received from sensor 42, controls visual level indicators 34 to activate the first element when sensor 42 indicates that base surface 23 is within 99% of levelness and controls visual level indicators 34 to activate the second element when sensor 42 indicates that base surface 23 is not within 99% of levelness. In such embodiments, where visual level indicators 34 and visual plumb indicators 26 are sets of at least two LEDs of different colors, controller 40 is configured to control each color LED separately. Controller 40 uses one color to indicate that vials 22 and 30 are indicating plumb or level, respectively. For example, when each set of LEDs includes at least one red LED and one green LED, controller 40 will receive a level signal from level/plumb sensor 42 when level 10 is horizontal and will generate and send a control signal to activate the green LED for visual level indicators 34 and the red LED for visual plumb indicators 26. When level 10 is vertical, controller 40 will receive a plumb signal from level/plumb sensor 42, and will generate and send a control signal to activate the red LED for visual level indicators 34 and the green LED for visual plumb indicators 26.

In another embodiment, visual level indicators 34 and plumb indicators 26 are single color LEDs. Controller 40 is configured to generate and send a control signal to fully activate the LEDs associated with either visual level indicators 34 or visual plumb indicators 26 based on the signal received from level/plumb sensor 42. For example, controller 40 will activate the LEDs for level indicators 34 when level 10 is approximately horizontal, and will activate the LEDs for plumb indicators 26 when level 10 is approximately vertical. In one such embodiment, controller 40 controls visual level indicators 34 and plumb indicators 26 such that when visual level indicators 34 are on, plumb indicators 26 are off, and when plumb indicators 26 are on, visual level indicators 34 are off.

If level/plumb sensor 42 sends continuous data to controller 40, controller 40 is configured to parse the data to determine when level 10 is 100 percent or nearly 100 percent level or plumb and use that determination to selectively activate the LEDs associated with either visual level indicators 34 or visual plumb indicators 26.

In another embodiment, controller 40 is configured to send control signals that dynamically adjust the LEDs associated with either visual level indicators 34 or visual plumb indicators 26 based on a continuous signal received from sensor 42 that corresponds directly to the current relative position of level 10. In one instance, controller 40 will gradually vary the brightness of the LEDs associated with visual plumb indicators 26 and visual level indicators 34 between 0 to 100 percent bright. In another embodiment, controller 40 is configured to vary the pulse rate of the LEDs associated with visual plumb indicators 26 and visual level indicators 34. In another embodiment, controller 40 varies both the brightness and the pulse rate duration.

For example, controller 40 operates the LEDs associated with visual plumb indicators 26 to be 100 percent bright and constantly on when level 10 is vertical and then dims the LEDs and/or reduces the pulse rate as level 10 is rotated away from vertical towards horizontal. Controller 40 will turn off the LEDs once level 10 passes a set crossover points such as 50 or 75 percent plumb. Controller 40 operates the LEDs associated with visual level indicators 34 in the same way except that it is 100 percent bright and constantly on when level 10 is horizontal and 0 percent bright and off at a set crossover point such as 50 or 75 percent level.

The multi-color LED setup can be operated similarly to the single LED setup with respect to varying LED brightness and pulse rate. Each colored LED for both the visual level indicators 34 and visual plumb indicators 26 are separately controllable by controller 40. This controllability provides additional modes of operation.

In one embodiment, controller 40 is configured to operate one color of LEDs, such as the green LEDs, in the same manner as described above for a system having one color of LED. For example, controller 40 operates the green LED associated with visual plumb indicators 26 to be 100 percent bright and constantly on when level 10 is vertical and then dims the LED and/or reduces the pulse rate as level 10 is rotated away from vertical towards horizontal. Controller 40 will turn off the green LED once level 10 passes a set crossover point such as 50 or 75 percent plumb. Controller 40 operates the green LED associated with visual level indicators 34 in the same way except that it is 100 percent bright and constantly on when level 10 is horizontal and 0 percent bright and off at a set crossover point such as 50 or 75 percent level.

In one embodiment, controller 40 operates the second colored LEDs associated with visual level indicators 34 and visual plumb indicators 26, such as the Red LEDs, to be 100 percent on whenever the green LED associated with the same indicator is off. For example, controller 40 operates the red LED associated with visual plumb indicators 26 to be 100 percent bright and constantly on when level 10 is past the set crossover point (e.g. 50 or 75 percent plumb) for the green LED associated with visual plumb indicators 26. Controller 40 operates the red LED associated with visual level indicators 34 in the same way except that it is 100 percent bright and constantly on when level 10 is past the set crossover point (e.g. 50 or 75 percent level) for the green LED associated with visual level indicators 34.

In another embodiment, controller 40 operates the second colored LEDs associated with visual level indicators 34 and visual plumb indicators 26, such as the red LEDs, to vary the brightness and/or pulse rate during a period when the green LED associated with the same indicator is off. For example, controller 40 operates the red LED associated with visual level indicators 34 to be 100 percent bright and constantly on when level 10 is vertical and then dims the LED and/or reduces the pulse rate as level 10 is rotated away from vertical towards horizontal. Controller 40 will turn off the red LED once level 10 passes a set crossover point such as 50 or 75 percent plumb. Controller 40 operates the red LED associated with visual plumb indicators 26 in the same way except that it is 100 percent bright and constantly on when level 10 is horizontal and 0 percent bright and off at a set crossover point such as 50 or 75 percent level.

In one embodiment, controller 40 dynamically adjusts the multi-colored LEDs as described above by sending an identical control signal simultaneously to the LED of one color associated with the visual level indicators 34 and to the LED of the opposite color associated with visual plumb indicators 26. For example, controller 40 sends an identical control signal to the green LED associated with visual level indicators 34 and to the red LED of visual plumb indicators 26. Controller 40 would also send an identical control signal to the red LED associated with visual level indicators 34 and to the green LED of visual plumb indicators 26.

In another embodiment, controller 40 operates the second colored LEDs associated with visual level indicators 34 and visual plumb indicators 26, such as the red LEDs, to vary the brightness to be opposite the varied brightness of the other LED associated with the same indicator. This embodiment displays a composite color of the two LEDs for the period when both are activated. For example, where the LEDs are red and green, various shades of yellow will be observed when both LEDs associated with the same indicator are activated and being dimmed and brightened opposite each other.

For example, controller 40 operates the green LED associated with visual plumb indicators 26 to be 100 percent bright when level 10 is vertical and then dims the LED as level 10 is rotated away from vertical towards horizontal. Controller 40 will turn off the green LED once level 10 passes a set crossover point such as 50 or 75 percent plumb. Controller 40 simultaneously operates the red LED associated with visual plumb indicators 26 to be 0 percent bright when level 10 is vertical and then brightens the red LED as level 10 is rotated away from vertical towards horizontal. Controller 40 will turn the red LED to 100 percent bright once level 10 passes the same crossover point that controller 40 uses to turn off the green LED. Additionally, controller 40 operates the green and red LEDs associated with visual level indicators 34 in the same way. Except, the green LED is 100 percent bright and the red LED is 0 percent bright when level 10 is horizontal and the green LED is 0 percent bright and the red LED is 100 percent bright at a set crossover point such as 50 or 75 percent level.

In one embodiment, controller 40 is configured to operate audio indicator 18 by sending a digital control signal to audio indicator 18. Audio indicator 18 includes a digital to analog converter which converts the digital control signal into an analog signal that is produced by speaker 36. In another embodiment, controller 40 sends an analog control signal to audio indicator 18 which is then produced by speaker 36. In one embodiment, audio indictor 18 and speaker 36 are a digital speaker configured to produce a specific tone in response to a specific digital control signal sent from controller 40. Various methods of operating audio indicator 18 are contemplated any of which may be combined with the various methods described regarding operation of visual level indicators 34 and visual plumb indicators 26.

In one embodiment, controller 40 sends a control signal to fully activate audio indicator 18 based on the signal received from sensor 42. For example, controller 40 will activate audio indicator 18 when level 10 is approximately horizontal or vertical. If level/plumb sensor 42 sends continuous data to controller 40, controller 40 is configured to parse said data to determine when level 10 is 100 percent or nearly 100 percent level or plumb and use that determination to activate audio indicator 18.

In another embodiment, controller 40 is configured to send control signals that dynamically adjust the tone produced by audio indicator 18 based on a continuous signal received from level/plumb sensor 42 that corresponds directly to the current relative position of level 10. In one instance, controller 40 will gradually vary the volume of the tone between 0 and 100 percent loud. In another embodiment, controller 40 is configured to vary the pulse rate of the tone between no pulses and constantly activated. In another embodiment, controller 40 is configured to vary the pitch of the tone from low to high or high to low.

For example, controller 40 operates audio indicator 18 to produce a tone that is 100 percent loud, high pitched, and/or constantly on when level 10 is vertical and/or horizontal and then lowers the volume, lowers the pitch and/or reduces the pulse rate as level 10 is rotated away from vertical and/or horizontal. Controller 40 will turn off audio indicator 18 to silence the tone once level 10 passes set crossover points such as 50 or 75 percent plumb or level.

In one embodiment, level 10 includes a switch coupled to controller 40. The switch is configured to operate controller 40 between different modes including an off mode. In off mode, controller 40 will not send any control signal to visual level indicators 34, audio indicator 18, and/or visual plumb indicators 26. In one instance, power is disconnected from all the electrical components while level 10 is in off mode. Other selectable modes can include the various methods of operation described above with respect to visual level indicators 34, audio indicator 18, and visual plumb indicators 26. In one embodiment, the switch is mounted in housing 12 and is selectable from the outside of level 10. In another embodiment, the switch is mounted contiguously with controller 40 and is selectable by removing controller 40 from inside housing 12. In another embodiment, level 10 includes a separate switch for the audio and visual indicators for each vial.
