This invention relates to the field of toilet fixtures and more particularly to a system for improving sanitation in the vicinity of the toilet fixtures.
An emission of urine from animals creates a breading ground for odor and bacteria. Although urine is a sterile fluid as it leaves the body of most animals, due to its temperature and composition, it quickly becomes a breading ground for bacteria and odor.
An efficient system has been introduced to most of the world's population to safely dispose of urine. At the terminus of such a system is typically a sewerage treatment plant that processes effluent, including the urine, in a safe manner. At the start of the system is a fixture such as a flush toilet or wall-urinal. After urination, the fixture is typically flushed with fresh water to wash the urine through plumbing and eventually to the sewerage treatment plant.
Although humans can sit on a toilet fixture to urinate, particularly for the male human, urination is often performed while standing. This provides for a more efficient, less time consuming process, but, due to the distance between the source of the urine and the fixture, this process often results in over spray due to splashing, bad aim or carelessness, resulting in urine landing on surfaces of the fixtures that do not get rinsed with water during the flushing operation. Furthermore, in some situations, the lack of aim results in urine on surfaces around the fixture such as walls and floors. Once urine is allowed onto these surfaces, the urine starts to grow bacteria, create an odor. A stain on the surfaces, particularly grout between tiles is also possible. The bacteria, odor and stain are large problems, especially with regard to public bathrooms where there is often a lack of regard or care in aiming correctly, possibly because the urinator is not in charge of cleaning up after themselves.
It has long been known to place target decals in a toilet bowl or urinal to help some with their aim. In general, such targets are decals or printing of a specific artwork, typically representing a target bulls eye. Although these devices provide a target at which to aim, they soon become boring and are quickly ignored.
What is needed is a urinal target system that will improve the likelihood that a standing urinator will correctly aim, thereby reducing urine deposits around the toilet/urinal.
A urinal target system is disclosed having a target area and a display (e.g. score board). In some embodiments, the target area is customizable, in that, an image is embedded or attached to in the target area to make it more fun to hit the target. For example, one might use a picture of a political person, a boss, sports team logo or a family member, thereby providing entertainment value while also providing an interesting target that will improve the chances of hitting the target and missing the surrounding walls and floors. The urinal target system has display and controller that adds an element of competition and achievement. The urinal target system displays a score for the urinator that is proportional to the length of time that the target is hit and/or the pressure exerted on the target, so a urinator with good aim is more likely to achieve a higher score than one with bad aim.
In one embodiment, a urinal target system is disclosed including a base member having at least a back wall and a cover member. The cover member has at least a front wall, is movably interfaced to the base member, and is urged away from the base member by a resilient member such that a flow of urine applies a force to the front wall of the cover member thereby the force counteracts the spring, moving the front wall of the cover member closer to the back wall of the base member. A display is mounted within the urinal target system and a display area of the display is visible through a window in the cover member. A sensor is coupled to the urinal target system such that the sensor detects the force and the sensor converts the force into an electrical signal, the electrical signal being proportional to the force of the flow of the urine. A processor mounted within the urinal target system is interfaced to the display. The processor is electrically interfaced to the sensor such that the processor receives the electrical signal from the sensor that is proportional to the force.
In another embodiment, a method of improving aim of a person that is urinating is disclosed including the steps of (a) directing the flow of the urine towards an outside surface of a urinal target system. The urinal target system has a base member with at least a back wall and a cover member with at least a front wall. The cover member is movably interfaced to the base member and is urged away from the base member by a spring such that a flow of urine applying a force to an outside surface of the front wall of the cover member counteracts the spring, moving the front wall of the cover member closer to the back wall of the base member. A sensor is coupled to the urinal target system such that the sensor detects the force from the flow of the urine and converts the force into an electrical signal, the electrical signal being proportional to the force of the flow of the urine. A processor (or electronic circuit) is interfaced to the sensor such that the processor receives the electrical signal. A display is housed within the urinal target system and a display area of the display is visible through a window in the cover member. (b) Software running on the processor calculates a score value that is a function of at least the force of the flow of the urine and (c) the software illuminates the display dependent on the score value. (d) After the flow of urine abates, the software running on the processor delays for a period of time, and then blanks the display.
In another embodiment, a target system is disclosed including a cover member and a device for resiliently supporting the cover member and/or electronics away from a wall of a toilet. The target system includes a device for measuring a force from a flow of urine applied as the flow is applied to the device for supporting the target graphics. The device for supporting is interfaced to the wall of the toilet/urinal. A device for displaying has a display area visible through the cover member and there is a system for changing an output of the device for displaying, the changing being dependent upon the score value.

Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

The micro-controller 100 and other circuitry 10/60/40/30 is powered by a source of power such as a battery 90. Power from the battery 90 is regulated by a regulator 92 to provide the operating voltage required by the other components 100/10/40 as known in the industry, though in some embodiments, some or all components are powered directly by the battery 90 without any regulation. Other sources of power such as solar power, charged capacitors, etc. are equally anticipated.
The micro-controller 100 is interfaced to a display 10 as known in the industry through a direct, serial, or parallel interface.
The output device 10 is shown as a display 10 as an example of an output device. Any suitable output device 10 is anticipated such as a TN display (twisted nematic), STN display (super-twisted nematic), LED display, OLED display, or TFT display (thin film transistor), etc. In alternate embodiments, the output device 10 is an audio output device. It is desired that the display consume as little power as possible to maintain maximum battery life. Although many display configurations are possible (e.g. dot-matrix, 13-segment, bar-graph, discrete LEDs, etc.), a multi-digit, seven-segment display is shown in the examples, being low cost and very good at displaying numerical data such as the urinator's score.
Although not required, a status indicator 60/62 such as an LED 60 with current-limiting resistor 62 is provided in some embodiments. This optional status indicator 60/62 is illuminated in various ways to indicate normal operation, failure and/or low-battery. For example, a flash every 3 seconds indicates normal operation, a flash every 10 seconds indicates low battery and no flash indicates a dead battery or other failure.
A sensor 30 is interface to the micro-controller 100 as known in the industry. In this example, an amplifier 40 conditions the signal from the sensor 30 and provides a voltage value to the micro-controller analog-to-digital converter input port (ADC). This is but an example of a way to sense a value from a sensor 30 as there are many ways known in the industry, all of which are included here within. The sensor 30 is any sensor 30 known in the industry that is capable of detecting the start, continuation and stop of a liquid flow, in particular a flow of urine. The types of sensors 30 include, but are not limited to, pressure sensors, Hall Effect sensors, strain gauges, etc. For example, a magnet 30 (see

In the exemplary housing of
The sensor 30 is housed within the target housing 36/38. How and where the sensor 30 is mounted is dependent upon the type of sensor 30. In this example, a Hall Effect sensor 30 is shown mounted to a back wall of the base 30 of the target housing 36/38. A magnet 32 is mounted in the target cover 36. The target cover 36 is movably attached to the target base 38 and is urged outwardly away from the target base 38 by a spring 34. Preferably, an outer surface of a front wall of the target cover 36 has a printed target graphic 42 that is visible for the urinator to take aim. As urine flows onto the target cover 36, pressure from the flow of urine against the front wall of the target cover 36 counteracts the force of the spring 34 and the magnet 32 moves closer to the Hall Effect sensor 30, resulting in an electrical change across the sensor 30. The sensor 30 is interfaced to the micro-controller 100 by wires running through the bridge 14. The micro-controller 100 determines the pressure and flow length from the electrical change and determines a score value that is then displayed on the display 10.

A program is stored in the program/data storage 125 and initializes operation when power is applied to the urinal target system 5 (or reset switch 60 operated). The program reads the urine pressure from a sensor 30 and, optionally, a status of a reset switch 60 through an input port or ports 142. The program writes to the display 10 through an output port or ports 140. In some embodiments, a power/status indicator LED 105 is present and the program writes to the indication LED 105 through an output port 140. In such, the power/status indicator LED 105 is controlled by software and indicates status such as the urinal target system 5 is powered and/or operational. For example, the power/status indicator LED 105 is controlled to blink on periodically for short periods of time to signal that the internal battery 90 has sufficient capacity and the urinal target system is operational. Any other indication scheme is anticipated such as blinking at different rates to signal a low battery, using multiple-color LEDs, of which one color indicates a good status and another color indicates a low battery, etc.
In some embodiments, the input ports 142 and output ports 140 are connected to the central processing unit 100 by a bus 130 (e.g. SPI bus, etc) as known in the industry.
In some embodiments the controller system 99 includes an interface 144 connected to a bi-directional port 143. This interface 144 provides external access for such things as modifying behaviors, reloading stored programs, loading graphical images, charging an internal battery, adjusting parameters such as brightness, sound levels, etc. Any interface 144 is anticipated, including, but not limited to, a USB interface 144 (shown), Bluetooth, Ethernet, WiFi (802.11x), serial, etc. When a graphics display 210 is used (see

Next, the program reads 201 the sensor 30 to determine if a flow of urine 3 is in progress. Flow of urine is determined, for example, by reading the sensor 30 and determining if the force of the flow of urine 3 is greater than a predetermined threshold (THR) which, in some embodiments is any pressure greater than zero. If no flow of urine 3 is detected 202, the program loops 201/202 until flow is detected 202 (e.g. urine has started hitting the target). The program now resets scoring variables 204, in this example, delta-time (DT) which represents the amount of time that urine pressure continually hits the target cover 36. The display 10 is now set to display all zeros 206.
Now the program enters a loop to measure the time and force of the urine flow 3. In this example, the program reads 207 the sensor 30 to determine if the flow of urine 3 is still in progress. Again, flow of urine 3 is determined, for example, by reading the sensor 30 and determining if the force of the flow of urine 3 is greater than a predetermined threshold (THR) which, in some embodiments is any pressure greater than zero. If a continuation of flow of urine 3 is detected 208, the delta time (DT) is incremented 210 and a score is calculated based upon a function of the force (F) of the flow of urine 3 and/or the delta-time (DT) and the score is displayed 212 on the display 10. For each loop, the optional reset switch is checked 214 and if pressed, the program exits the loop and reinitialized 200. If no reset 222, the program repeats the loop 207/208/210/212/220/222/224. In some embodiments, a fixed delay is inserted in the loop to add proportion to delta-time (DT). For example, a one-second delay is inserted in the loop before reading the sensor 207 and, therefore, delta-time (DT) represents the number of seconds that the flow of urine 3 continues.
Once the flow of urine 3 falls below the threshold (THR) 208, a short loop 220/222/224/226 provides hysteresis, for example, if the urinator veers the flow of urine 3 away from the target for a short duration. The loop 220/222/224/226 begins with setting a timer 220 which, in some embodiments, is an initialization of a variable to a preset value (e.g. zero). In other embodiments, the timer is a hardware time of the processor 100. The timer is checked 222 to see if it has expired (e.g. reached a terminal count or the hardware timer expired). If the timer has expired 222, the program resets 200 (e.g. it has been surmised that the flow of urine 3 is stopped). If the timer has not expired 222, for embodiments utilizing a counter to perform the timing function, the timer is incremented (or decremented, etc.) and the program reads 224 the sensor 30 to determine if the flow of urine 3 is still in progress. Again, flow of urine 3 is determined, for example, by reading the sensor 30 and determining 226 if the force of the flow of urine 3 is greater than a predetermined threshold (THR) which, in some embodiments is any pressure greater than zero. If the force of the flow of urine 3 is still not greater than a predetermined threshold (THR), the hysteresis loop continues 222/224/226 until either the timer expires 222 or it is determined 226 that the force of the flow of urine 3 becomes greater than a predetermined threshold (THR), at which time the display loop is re-entered to display the score 212.
Again, this is an example of one embodiment of a program that monitors the force of a flow of urine 3 and converts the force and/or length of time of the flow of urine 3 into a score.
The scoring function 212 is any function that provides a score value that is proportional to either a length of time (delta-time or DT) of the flow of urine 3, force of the flow of urine 3 (F) or both. For example, one exemplary scoring function 212 provides a score value that is equal to the length of time (DT) plus the force (F). So, as long as the urinator hits the target, the score continues to increase (e.g. delta-time increases) and if the urinator provides a high force, a higher force value is added or, in some examples, if the urinator provides a low force, a higher value is added to the score value. The latter provides an incentive to the urinator to control the flow to a lower force, thereby reducing splashing.

In this example, the sensor 30 is interfaced to a circuit board 101 that also holds the processor 100 and display 10. Mounting of the sensor 30 is mounted is dependent upon the type of sensor 30. In some examples, the target cover 36a has a printed target graphic 42 that is visible for the urinator to take aim. As urine flows onto the target cover 36a, pressure from the flow of urine counteracts the force of the spring 105 and the target cover 36a is forced closer to the target base 38a. This brings the magnet 32 closer to the Hall Effect sensor 30. The Hall Effect sensor 30 converts the urine pressure into an electrical signal that is interfaced to the controller system 99. The micro-controller 100 determines a score based upon either the pressure and/or a flow length (e.g. the length of time of urination). The score is then displayed on the display 10, visible through a window 15 in the target cover 36a. Although a numeric display 10 is shown, any other output device is anticipated such as a blinking LED in which the LED blinks faster when the score value is higher or the LED changes color and/or blinks dependent upon the score value. Another example of an alternate/small display 10 is a single digit seven-segment display which displays a score value of from 0 to 9 but, in some embodiments, is sequenced to indicate even higher score values. For example, the outer 6 segments of a single digit display 10 are sequenced to indicate a score higher than 9. An example of another alternate scoring output is an audible sound emitter such as a Piezo sound transducer that emits a beep and the period and/or frequency of the beep changes proportional to the score value.
