- 1 Improvements to a Clock

Field of the Invention

The invention relates to clocks, and in particular clocks capable of producing random time outputs.

Background to the Invention

In the world of quantum physics, the act of observing an event, according to the standard interpretation, has a direct effect on that event. The best known illustration of this concept is Schrodinger's cat. In this experiment, Schrodinger invites you to imagine a cat trapped in a box; inside the box is a very low dose radio-active source and a Geiger counter that is connected to a hammer poised over a glass capsule containing hydrocyanic acid.

Radioactive decay is an uncertain process, but if the radioactive material decays and releases a single particle that is detected by the Geiger counter, the hammer is released, the glass capsule is broken, the gas is released and the cat dies immediately. From outside the box we cannot tell whether the cat is alive or dead and therefore, until the box is opened it can be considered to be in both states. When the box is opened, and the cat observed, its state is then determined. What Schrodinger was trying to demonstrate was the uncertainty relating to observation within quantum mechanics.

Despite the apparent paradox defined by Schrodinger's thought experiment, the concepts of quantum mechanics are inextricably linked to those of probability; orthodox quantum mechanics, as understood for example under the Copenhagen interpretation, can be reformulated in a quantum-probabilistic framework.

As with most complex theoretical ideas, the notions of quantum physics and probability are easiest to understand with the use of everyday known examples. In this case a clock provides the perfect framework upon which to build the concepts of uncertainty and probability.

Concepts of time and the functioning of clocks are amongst the first things we teach young children, and by adulthood they are second nature to most. As such we take for granted that they are a constant; predictable in the changing of the clock face as a representation of the passing of time. But what happens if we remove the certainty of the clock, and suggest that sometimes the clock will display the wrong time?

When we consider the clock in light of the teachings of Schrodinger, we can, to put it simply, see that before we observe the clock we must consider that the clock is both right and wrong. Furthermore, we can propose probabilities to describe the ratio of true and false outputs provided by the clock face.

In Schrodinger's example, there is a 50:50 chance that the cat will be alive when the box is opened. This is the same as flipping a coin for determining the state of the cat. The current invention includes a means to vary the probability of the right time being displayed.

The current invention expands on these concepts, providing a clock which exposes these ideas of probability and uncertainty, by a means that is relatable for all.

Summary of the Invention

In a first broad independent aspect, the invention provides a time monitoring system for providing either a current local time or a random time comprising:

• a means for receiving time information from an external system.;

• a means for providing real time information from said time information;

• a means for providing random time information;

• a display means for displaying said random time information; and • a switch which in a first state enables a first selection means to communicate said real time information to said display means; preferably said real time information is displayed continuously, and in a second state enables a second selection means to communicate said real time information and said random time information to said display means; preferably said real time information and/or said random time information are displayed alternatively.

This is particularly advantageous because it provides a system, e.g. a software application that provides a means for understanding the confusing concept of quantum uncertainty in a relatable manner. The time displayed by the display means on a computer or mobile computer and/or communication device which can be construed as the cat from the famous Schrodinger's cat example, with the option that until viewed, the activation by the switch, the time is both right and wrong. The activation of the switch can be also be construed as the opening of the box to see the cat contained within.

This configuration is advantageous because each second based time duration in the app is marked out by an audible tick tock sound, whereby the Tick Tock sound is synchronised with the system ‘tick-tock’ time pulse. The system, i.e. a software application, displays either the time from the cellular phone network (NOW - local time) or a random time. If an Observer is detected, the time shown is always NOW. The camera captures an image every second. If it detects an Observer's face, this is recognized (in the normal mode) by superimposing a pair of cat's eyes on the Observer's face/ There is a low-light level option - Night mode where the smart phone screen is used to illuminate the face of the Observer. In this mode, if an Observer is detected, the face is not shown instead an alternative screen is displayed, such as a Schrodinger's Cat logo is displayed together with a quote from Dumas' book ‘The Three Musketeers' where the title of Chapter 35 is All Cats are alike Gray in the Dark”.

Furthermore the time information may be provided from a recognized national or international time standard, including the United Kingdom's MSF time signal, or from a cellular phone signal, or from a Global Positioning System [GPS] time signal;

Preferably, said real time information and information from a means for a time from another time zone are communicated to said second selection means, which in use, selects either said real time information or information from a means for a time from another time zone upon activation of said switch.

Preferably, a time monitoring system further comprising a probability generator for providing probability information indicative of selecting the probability of selecting said real time information, to said second selection means. This configuration is advantageous because the probability controller determines probability that the said display shows the right time. The probability can be set from multiple probabilities, e.g. 1:2 (flipping a coin) through 1:6 (rolling a dice) to 1:14,000,000 (typical lottery odds).

Preferably, said switch is an actuator device, a graphical user interface element or a face detection means for determining the presence of a user. This configuration is advantageous because the system employs a camera for detecting the presence of an observer, and a graphical user interface, or touch screen or other haptic interface, to select functions and display time and detected face.

Preferably, a computer program comprising a time monitoring system according to any of the above features.

In a second broad independent aspect, the invention provides a clock comprising a clock face on which a time reading is displayed; a sensor for determining when said clock face is being observed; a processor including a time-state generator and a probability calculator, the processor being operatively linked to said clock face so that outputs displayed on said clock face are controlled by said processor; said processor accepting inputs from said sensor and providing an output for display on said clock face, said output being selected from a true output or a false output on the basis of said inputs; a random number generator controlled by said processor and providing a random time to be displayed on said clock face when a false output is determined by said processor.

This is particularly advantageous because it provides the framework to understand the confusing concept of quantum uncertainty in a relatable manner. The time displayed on the clock face can be regarded as the cat from the famous Schrodinger's cat example, with the option that until viewed the time is both right and wrong.

In a subsidiary aspect, the sensor is at least one of the following; a light sensor, a magnetic sensor, a pressure sensor, a mechanical or electrical sensor linked to the opening of a lid or a camera facing substantially the same direction as the clock face. This is advantageous because it enables the clock to determine when it is being observed and therefore determine the relevant output to display.

In a further subsidiary aspect, the clock further comprises facial recognition software able to determine eye gaze direction of an observer. This is particularly advantageous because it enables the clock to determine if it is being observed without the assistance of a clock face cover. As a result, the clock face can be left uncovered and viewed from remote locations without first uncovering it.

In a further subsidiary aspect, the random number generator is based on an inherently unpredictable physical phenomenon. This is advantageous because it represents a true random number that is not governed by any mathematical formula. As such, it aligns closest to the concepts of quantum mechanics and probability that the clock seeks to demonstrate.

In a further subsidiary aspect, the physical phenomenon recorded is thermal noise.

In a further subsidiary aspect, the random number generator further comprises a transducer to convert said physical phenomenon into an electrical signal.

In a further subsidiary aspect, the clock further comprises a switch to select one of a plurality of predetermined probabilities, wherein said probabilities affect the ratio of true and false outputs from said processor. This is particularly advantageous because the ability to alter the probability of a correct time being displayed, allows the user to gain a better understanding of probability and chance.

In a further subsidiary aspect, the processor provides true or false outputs at predetermined time intervals.

In a further subsidiary aspect, the time intervals can be altered by the user. This is advantageous because it enable the user to tailor the function of the clock and reduce the power usage associated with the constant processing.

In a further subsidiary aspect, the clock further comprises a switch for switching ON the clock and/or the probability engine.

In a further subsidiary aspect, the clock further comprises a wireless signal receiver and a controller for controlling the operation of said clock.

In a further subsidiary aspect, the controller is configured to select one of a plurality of predetermined probabilities for input into the processor dependent upon a signal received by said receiver.

In a further subsidiary aspect, the clock further comprises a cover for said clock face. This is particularly advantageous because it provides a simple means of determining when the clock is being observed. The cover may also be the lid to the box that contains the entire clock. In addition, the cover increases the illusion of uncertainty and correlates with the ‘cat in a box' experiment.

In a further subsidiary aspect, the cover obscures the sensor and assists in detecting when the clock face is being observed.

In a further subsidiary aspect, the clock further comprises the means of wirelessly syncing with external time sources. This is advantageous because it ensures the clock is always correct when displaying a true output. It also prevents the need of setting the clock or remembering to adjust the time when the clocks go forward or back for daylight saving.

In a further subsidiary aspect, the clock further comprises a means of producing a series of predetermined sounds. This is advantageous because the sounds help to indicate to the user when the display has changed. In addition, it helps to indicate to the user when the display is correct and when it is wrong.

In a further subsidiary aspect, the clock further comprises a means of recording and storing 5 sounds. This is advantageous because it enables the user to personalize the sounds created as the clock changes modes and the display changes.

In a further subsidiary aspect, the clock further comprises a means of taking and storing pictures. This is advantageous because it enables the clock to recognise faces of certain individuals, providing a different display depending on the person observing it.

Detailed Description of the Figures

Understanding concepts of quantum mechanics and probability are daunting tasks for most people. A thorough understanding becomes even more challenging by the fact that these topics are dealt almost exclusively in a theoretical manner. By providing a tangible example of these ideas in action, the current invention provides a means of demonstrating to individuals these concepts whilst also accurately displaying the time when required.

To provide clarity, the components of the system which are common to different figures have retained identical numerical references throughout all figure descriptions.

Figure 6 shows a decision tree for determining the output displayed on the clock face. Each decision computed by the internal processor and determined based on the individual situation inputs. By travelling through the decision tree it is possible to understand the purpose and functionality of the clock. The initial decision 31, is what mode the clock is set to by the user. In a preferred embodiment the clock 1 has four modes of operation which may be selected using a switch on a control panel in the clock:

1. Schrodinger's clock mode - In this mode, when not observed the clock switches between the right and wrong time at set time intervals and based on set probabilities. When observed the output shown on the clock face will ‘freeze’, regardless of whether it represents the right or wrong time, for a fixed time period, after which, if still observed, the correct time (NOW) will automatically be shown on the clock face.

2. Counter-intuitive improbability mode - In this mode, when not observed the clock will always show the wrong time. When observed the clock will show the right or the wrong time based on set probabilities and changing at set time intervals.

3. Lewis Carroll mode - In this mode the time displayed on the clock face is frozen from the moment the clock enters Lewis Carroll mode. Whilst in this mode the clock will compare the time frozen on the display with the correct time every minute. The clock will display WRONG when the frozen displayed time and the actual local time are not in agreement and will display NOW when the frozen displayed time and the actual local time are in agreement. In another embodiment, Lewis Carroll mode includes the capacity to compare frozen displayed time with a lookup table of times at different locations. When the frozen displayed time is the same as the time at one of these locations the clock will display the name of the location where the frozen displayed time is correct (NOW).

4. Local mode - In this mode, the clock displays the correct local time only indicated as ‘NOW’. All other functions are disabled apart from the clock reset sound.

The next stage is to determine whether the clock 1 is being observed 32 and 33. Based on decision 31, this decision of observation can have alternative outcomes. Observation when in Schrodinger's clock mode will result in the right time 34 being displayed on the clock face. By contrast, observation when in Counter-intuitive improbability mode, will move onto the next decision process step 36, which involves a probability function. These probability calculations 35 and 36, are performed by the processor 16 (See Figure 5), and are determined by pre-set and alterable probabilities. The result of this calculation will either be the right 38 and 40, or the wrong time 39 and 41 being displayed on the clock face.

In a preferred embodiment a system clock pulse will reset this decision-making process at certain time intervals which can be altered using the clock's interface system. The default setting will be at 1 second intervals. For example, the random-time generator, the probability generator and the processor can all be reset by the clock pulse.

Figure 1 shows an embodiment of a digital clock 1. The clock face 3 of the clock 1 is housed in a casing 2. The casing 2 can be plastic, wooden, metal or any appropriate material. In addition, the casing 2 can be substantially transparent or opaque. A probability switch 4 enables the user to select from a plurality of predetermined probabilities for input into the processor 16 (See Figure 5). In a preferred embodiment the probability switch 4, is a sliding switch where each switch position corresponds to a separate probability. In an alternative embodiment the probability switch 4 can exist as one or more buttons for selecting predetermined probabilities. In a further embodiment, the probability switch 4 enables the user to input probabilities independent of predetermined options.

The clock face 3 provides the time in addition to an indicator 5 which displays whether the time provided is correct or not. The indicator 5 can include, for example, pairs of words such as: ‘right’ and ‘wrong’, ‘true’ and ‘false’, ‘dead’ and ‘alive’ (as an allusion to Schrodinger's Cat). In a further embodiment, the indicators can include the feature of coloured or flashing wording to ensure easy visibility and understanding.

In a further embodiment, the clock face 3 includes a camera 6 facing in substantially the same direction as the clock face 3. In conjunction with facial recognition software 19 (See Figure 5), the camera 6 enables the clock to determine when it is being viewed. In one embodiment, facial recognition software 19 would be able to determine eye gaze direction and enable the clock 1 to determine accurately when the clock face 3 is being observed by a user. In a further embodiment, an observer detection system continually scans the area around to see if anyone is looking at the clock face 3. If the detection system concludes that the clock face 3 is being observed, then the processor 16 causes the clock face 3 to display the right time after a period of time so that the observer can observe the state of the clock at the moment of observation. If no observation is detected, then the processor 16 causes the clock face 3 to displays a random time. In a further embodiment, the clock 1 includes optical filters in clock face 3 to limit the spectral range of observation and ensure that the clock face 3 can only be observed from locations where the camera 6 can detect gaze direction. Information regarding observation of the clock face 3 is sent to the processor to help determine the output shown on the clock face 3. The camera 6 allows the clock face 3 to be visible from a distance whilst still retaining the feature of being able to detect when the clock face 3 is being observed.

Figure 2 shows a clock of the embodiment of figure 1 with the addition of a clock face cover 8 and buttons 7. In a preferred embodiment the cover 8 is hingeably attached to the casing 2 that contains the clock 1; this can be achieved along any edge. In a further embodiment, the cover 8 is fixed in position over the clock face 3 with the help of an alternative attachment means. In one embodiment the cover 8 is fixed in position by a clasp 12. The clasp 12 can be in addition to or alternative to a frictional push-fit connection between the cover 8 and the casing 2. The cover 8 includes a means for opening, in one embodiment this can be a handle 9. Alternatively, this can be an oversized ridge on the cover 8 which enables the user to easily pull the cover 8 from the casing 2. In a further embodiment, the handle 9 is hingeably attached to the cover 8, so that when the cover 8 is pulled away from the clock face 3 the handle 9 can lay flat against any surface the clock 1 is sitting upon.

In a preferred embodiment, the clock 1 has 2 or more buttons or switches 7, to allow the 5 user to switch between different settings and features.

In a preferred embodiment, the time intervals at which the outputs on the clock face 3 change, in any mode, can be altered using the buttons 7. The default setting for when the output is changed is 1 second. For example, when in Schrodinger's clock mode and not observed, the output on the clock face 3 will change every second. The ratio of right and wrong outputs displayed by the clock 1 is determined by the probability setting.

In a further embodiment, the probabilities can be set using either or both of the probability switch 4 and the buttons 7. Set probabilities can include well known probabilities such as:

1. 1 in 1 - certainty

2. 1 in 2 - the probability when flipping a coin

3. 1 in 6 - the probability of getting a six when rolling a dice

4. 1 in 36 - the probability of getting two sixes when rolling two dice

5. 1 in 37 - the probability of getting an individual number on a roulette wheel

6. 1 in 38 - the probability of getting an individual number on a US roulette wheel (except zero)

7. 1 in 52 - the probability when selecting from a standard UK deck of cards

8. 1 in 1,295 - the probability of rolling five aces with a set of poker dice

9. 1 in 45,000,000 - the approximate probability of winning the UK National lottery

10. The inverse of each of the above probabilities

In a preferred embodiment the probability settings can be changed to their inverse probabilities by the use of a separate switch. In a further embodiment, when in counter30 intuitive improbability mode, the clock 1 can be further altered so that when observed the output will be incorrect at the probability of winning the lottery.

In an alternative embodiment, a clock reset sound indicates to the user that the clock is altering the time being displayed or, in quantum mechanics terms, it is changing state. In a preferred embodiment the clock reset sound is a ‘tick’ such as those associated with mechanical clocks. In an alternative embodiment the clock reset sound could include one or more of the following; a buzzer, gong, beep, siren or purr. Alternatively, the clock reset sound could be a human or robotic voice saying words or short sentences, including· ‘right’, ‘wrong’, ‘change’, ‘true’, and ‘false’. The clock reset sound could represent a change from one specific output to another, such as from a true display output to a false display output. In that embodiment the sound would only be heard in the scenario when the clock changed from displaying a true display output to a false display output. Alternatively, the clock reset sound could be heard each time the clock changes display output, regardless of which output is being changed to which output. In a preferred embodiment there are several different sounds which the user can select to be the clock reset sound. In a further preferred embodiment, the user can select different clock reset sounds to be played during different transitions of display outputs. For example, the user could set the clock to play a ‘tick’ sound when the clock changed from displaying a false display output to a true display output, and a ‘buzz’ sound when the clock changed from displaying a true display output to a false display output. In an alternative embodiment, the clock incorporates a microphone, allowing the user to record one or more of their own sounds to be used for the clock reset sound.

Figure 3 shows the embodiment of the clock 1 shown in figure 2 with the alteration that the probability switch 4 is located on the upper surface of the casing 2. The cover 8 is shown in its open position with the clock face 3 exposed. Corresponding magnetic strips 10 on the inner surface of the cover 8 and outer surface of the casing 2 provide a mechanism for keeping the cover 8 in place over the clock face 3.

The sensor 11 provides a means of determining when the clock face 3 is being observed. The sensor 11 can be any one of the following; a light sensor, a pressure sensor, a magnetic sensor or a mechanical or electrical sensor linked to the opening of a lid. In use, this sensor can detect when the cover 8 is not obscuring the vision of the clock face 3, and switches the clock output in accordance with the mode set. For example, when in Schrodinger's clock mode, detection of observation by the sensor 11 would freeze the output shown on the clock face 3 and begin a pre-set internal countdown. At the end of this countdown the clock 1 would provide the right time on the clock face 3. Alternatively, when in counter-intuitive improbability mode, the sensing of observation by the sensor 11 would cause the output on the clock face 3 to change every second to either the right or wrong time based upon the selected probability setting.

In a preferred embodiment, when the clock detects that it is being observed - whether by sensor 11 or camera 6 - it initiates a display or makes a sound. These messages could include things such as Well hello there” or I see you”. The sound initiated when the clock detects that it is being observed is preferably a purring sound, however, it could be any recordable sound. In an alternative embodiment, there could be a third mode of operation called ‘Familiar mode'. In Familiar mode, the clock alternates between displaying the right and the wrong time at a pre-set probability while not observed. When observed, the clock continues to alternate between displaying the right and the wrong time, but at a probability setting one lower than it was previously set at. For example, if the clock was set to Familiar mode at a probability of 1 in 36, then while not observed, the clock would, on average, show the correct time every 36 seconds (if set to the default clock pulse setting of 1 second). When observed, the clock would switch to displaying the correct time at the probability setting one down, in this example showing the correct time, again on average, every 6 seconds.

In an embodiment, the clock has a store function such that when an observer wishes to have their image stored within the clock, the observer positions the clock to see the face of the observer, and then the store button is pressed to record the image of the face. This image is then used to determine whether any future observer is familiar or not.

Figure 4 shows an embodiment of clock 1 with the clock face 3 facing in an upward direction. The cover 8 is effectively a lid which is lifted to reveal the clock face 3. Again the cover 8 can be secured with a hinge along any length or entirely removable. The cover 8 is shown with magnetic fastening 10 but could also be secured with other forms of attachment. In this embodiment, the buttons 7 are shown on the front surface of casing 2 but could be housed on any feasible surface of the casing 2.

Figure 5 illustrates a circuit board 21 with components in block form. A random number generator 13 produces a random time when the processor 16 provides a signal to produce the wrong time. In a preferred embodiment, the random number generator 13 is a true random number generator and based on an inherently unpredictable physical phenomenon such as atmospheric or thermal noise. The true random number generators require the use of a transducer 14 to convert the physical phenomenon to an electrical signal.

Alternatively, the random number generator 13 could be a pseudo-random number generator which utilises computational algorithms which can produce long sequences of random numbers based on shorter seed sequences.

In a further embodiment, a wireless receiver 17 can enable the clock to be controlled by remote means. This can take the form of a remote control or a phone app. This allows the user to access and change the clock's settings and modes and alter them from remote locations. In a further embodiment, the wireless receiver 17 can alter the working of the magnetic fastening 10 allowing the cover 8 to be released from the clock face 3 in a remote fashion.

The processor 16 correlates inputs from the sensors 11 and the user defined mode and settings, and provides an output which could be considered true or false. This is a binary output with only 2 possible outcomes: the right or the wrong time. Additionally, a further option can be included from which to select, such as the time elsewhere. When the processor provides a false output, it sends a signal to the random number generator 13 which provides a random time to be displayed on the clock face 3.

In a preferred embodiment, a time keeping means 18 includes the function of selecting different time zones. In a preferred embodiment the clock includes the means to internally maintain the correct time whilst the wrong time is being the displayed on the clock face 3.

In further embodiment, the clock includes the means of wirelessly syncing with an external source of time, preventing the clock from displaying the wrong time under the descriptor that it is correct. In an embodiment, this wireless syncing is achieved using GPS or MSF technology. In one embodiment clock includes the option of selecting the time zones of planets in the solar system to improve the understanding of shifting concepts of time on neighbouring planets. In a preferred embodiment the clock has an internal catalogue of correct times from alternative locations. In certain selectable modes, the clock will display the correct time from its catalogue of correct times at alternative locations when processor 16 determines a false output. This would be an alternative to a random time, which is normally created as a false output. In a preferred embodiment, when the clock displays the time from an alternative location, the display shows which location the time is correct in.

In a preferred embodiment the clock 1 will be powered by mains attachment, however in a further embodiment the clock 1 can include a rechargeable battery capable of powering the clock when the clock 1 is not plugged in.

Figure 7 illustrates the workings of a further embodiment of a clock. The clock includes the feature of a comparator 51. The comparator 51 compares the random time generated by the random time generator 54 (analogous to random number generator 13), with the actual time as dictated by the internal time keeping means or via wireless communication with an external source of time. If the outputs are the same the comparator 51 causes the random time generator 54 to reset and produce another output. This ensures that the correct time is not displayed when the output should be false and the indicator 5, displays the wording false on clock face 3.

In a preferred embodiment, the clock includes a Lewis Carroll mode. In this mode the time displayed on the clock face is frozen from the moment the clock enters Lewis Carroll mode. This is achieved by selecting the Lewis Carroll mode from the control panel and then pressing the Store button. The clock will then store a random time and display this time until the mode is changed or the store button is pressed again. The clock's reset sound will continue but the display will not change. Whilst in this mode the clock will compare the time frozen on the display with the correct time every minute. The clock will display false when the frozen displayed time and the actual local time are not in agreement and will display true when the frozen displayed time and the actual local time are in agreement. In another embodiment, Lewis Carroll mode includes the capacity to compare frozen displayed time with a lookup table of times at different locations. When the frozen displayed time is the same as the time at one of these locations the clock will display the name of the location where the frozen displayed time is correct.

In the embodiment of Figure 7, the features of processor 16 have been separated into a selector 52 and display controller 53, although the concepts of control remain the same.

In preferred embodiment the clock can be set as a 24h or 12h clock. The 12h clock enables the Lewis Carroll mode to show the true time twice a day. Alternatively, the clock could be either a 24h clock or 12h clock exclusively.

Figure 8 illustrates an alternative embodiment of the invention which has been embodied in a software application program. The application may be in the form of application program may be installed and/or used in a mobile communication device, such as a phone, tablet or laptop computer; or a static computer device such as a desktop computer. When operated on a mobile communication device, only a small number of features are enabled and the user is directed to a web site for further information.

The application comprises a graphical user interface [GUI] and a camera, both of which integral or connected to a computer device. The GUI has a range of selectable probabilities, which are represented as a ratio for selecting the correct time (NOWO from a number of incorrect time probabilities [correct time: incorrect time]. When the camera detects the presence of a user, it will select a time from the available time probabilities. If the correct time is displayed (NOW), this will be the equivalent of opening Schrodinger's box and discovering the cat enclosed within the box is still alive [as in accordance with the Schrodinger's cat model]. If the camera selects an incorrect time, this will the equivalent of discovering the cat enclosed within the box is dead [again in accordance with Schrodinger's cat model].

The use of the camera to select a time from the probabilities and be replaced or bypassed through the use of a push button [separate from the GUI] or a touch sensitive pad which is also embedded within the GUI.

The range of probabilities are, but not limited to:

[correct time (NOW): incorrect time (Wrong)] • 1:1 • 1:2 [probability of selecting correct time is equivalent to flipping a coin];

• 1:6 [probability of selecting correct time is equivalent to throwing a dice];

• 1:36 [probability of selecting correct time is equivalent to selecting from a roulette wheel, or from throwing two dice];

• 1:52 [probability of selecting correct time is equivalent to selecting from a pack of playing cards];

· 1:14,000,000 [probability of selecting correct time is equivalent to winning a lottery].

The GUI may also have the following the selectable components:

• Look - this function selects the current time [equivalent to lifting the lid on the box to the Schrodingers' cat];

• Invert - this function selects inverses the probability of selecting the real time from the set number of probabilities;

• Face detection - this function selects the current time [equivalent to lifting the lid on the box to the Schrodingers' cat] when the camera detects the face of the user · Show time else - this function selects the viewing of the current time in other time zones when the selection of the current time has not been selected.

• Sound - this function select an audible clock tick.

The GUI may also have any of the following means for selecting and the displaying of the 20 current time in the local time zone, e.g. in the UK this would be Greenwich Mean Time [GMT] or British Summer Time (BST):

• A touch sensitive portion/panel of the GUI:

• A push button/mechanical switch · A camera device [as mentioned above]

The GUI will display the time and time zones in one or more digital dialogue boxes. The clock may also be displayed in an analogue clock face.

In use, the software application/program will:

• When the current time is not required, a dialogue box will display multiple time values in the form of HOURS:MINUTES:SECONDS. Each time value will be randomly selected and displayed for a predetermined time. A second dialogue box displays NOT NOW” or WRONG TIME” to the user, thus indicating that the displayed time is not the current local time.

• When the current time is required, via an input/stimulation from user via, the GUI, button and/or camera, the dialogue box will then display the current local in the form of HOURS:MINUTES:SECONDS. The time value will be displayed for as long as required. The second dialogue box will display NOW” or CORRECT TIME” to the user, thus indication that the displayed time is the current local time.

• When the current time is no longer required, the program will default to displaying random time values or the current local time again depending on the probability setting. Along with indicating to the user that the displayed time is either not the current local time or is correct (NOW).

· At any time during this operation, the user can select any of the selectable components displayed on the GUI.

• The GUI may also display a window which displays a real time image of the user. The user can determine if the camera has detected a recognisable face by superimposing a pair of cats eyes over the eyes of the user captured within the image. In another embodiment of the invention, which may be hardware platform dependent - such as the Raspberry PI [TM], the application may indicate the change of state, i.e. a user being detected, which uses face detection to detect the user and change the time displays accordingly • The application will be providing an audible sound on a one second looping count, just like a conventional clock. The sound can be the recording from a conventional mechanical clock with a mechanism using an escapement producing a distinctive sound.

Figure 9 shows an algorithmic diagram of how the components of the program communicate data/information signals and interconnections with other components.

In this diagram GPS real time information is communicated from a GPS/MSF component 101, to a real-time clock component 102 via arrow 103.

MSF is the UK national radio time signal provided by the UK based National Physics

Laboratory [NPL], It can also come from an internal real time clock component.

Real-time clock information is communicated from the real-time clock component 102 to a 50:50 selector module 104 via arrow 105.

A random time generator component 106 communicates random time information to the 50:50 selector module 104 via arrow 107.

Selected time information is communicated from the 50:50 selector component 104, to an observer detection module 108 via arrow 109.

if the observer detection component 108 determines that an observer has not been detected [e.g. facial recognition via camera or a much button switch], information indicative of time will be communicated to a display device 111 via arrow 110.

The display module 111 will display either the correct time (NOW) or the WRONG time, each for 50% of a display cycle, hence the term 50:50.

if the observer detection component 108 determines that an observer is present then information indicative of the observer being present is communicated to a time selector component 112, via arrow 113.

The time selector module 112 selects and communicates information from either the real time clock information 113, or the ELSEWHERE time information which is provided by the time elsewhere clock module 114. When the time selector module will communicate the information displaying the time to the display device 111. Or alternatively, send the information to a second display means [not shown], when upon receiving information indicative of an observer being detected 113. The communication of the time information from the time selector module 112 is via arrow 114.

A probability generator component 115 is a generator that select a probability ratio which is based upon a user selection. The selection being, but not limited to the following probabilities:

»1:2 [Typical flipping of a coin probability] • 1:6 [Typical throwing of a dice] • 1:36 [Typical throwing two dice] • 1:37 & 1:38 [Typical choosing a number on a roulette wheel] • 1:52 [Typical picking a card from a deck of cards] · 1:1295 [Typical throwing a set of five poker dice] • 1:14,000,000 [typical lottery probability]

The information indicative of the user selected probability is communicated to the time selector via arrow 116.

Information indicative of the selected probability is also communicated to an inverter component 117, via arrow 118, which then communicates the inverted information to the timer selector module 112, via arrow 118. The time selector will then be able to select and display a time based upon the inverse of the selected probability. E.g. 6:1 = 1 chance in 6 that the time will be wrong.

The real time information 105 is communicated to a comparator module 119, along with the information indicative of the random time via arrow 107. The random time information is provided by a random time generator 106. if the comparator detects that the random time information is equal to the real tie clock information [e.g. random time = real time] the comparator module 119 will generate a reset signal 120. The reset signal 120 is then communicated back to the random time generator 106, which then subsequently generates a new random time that is then communicated back to the comparator module 119.

The overall clock system is driven and synced to a master system clock component 121. The system clock component 121 generates multiple clock pulses which are then communicated to the random time generator component 106 via arrow 122. The clock also provides pulses which are then communicated to a clock Tick - Tock sound generator 125, via arrow 124.

The system clock also communicates clock pulse information to the display device 111 via arrow 125.

The display device 111 is typically an Liquid Crystal Display [LCD[ device or a Light Emitting Diode [LED] device. However, other forms of display may be used, which may also have buttons or touch screen components for selecting the functions e.g., probability inverse, simulated observer and/or probability options; other functions are also envisaged.

The display device is typically a computer generated/rendered display, such as a Graphical User Interface [GUI] on a mobile communication/computer device. The GUI may embedded in a software application which is embedded within, but not limited to, Apple IOS [TM] or

Android [TM] mobile operating system. Or alternatively embedded in conventional operating systems for static computer devices.

In use, each second based time duration in the app is marked out by an audible tick tock sound, whereby the Tick Tock sound is synchronised with the system ‘tick-tock’ time pulse.

The system, i.e. a software application, displays either the time from the cellular phone network (NOW - local time) or a random time. If an Observer is detected, the time shown is always NOW. The camera captures an image every second. If it detects an Observer's face, this is recognized (in the normal mode) by superimposing a pair of cat's eyes on the Observer's face/ There is a low-light level option - Night mode - where the smart phone screen is used to illuminate the face of the Observer. In this mode, if an Observer is detected, the face is not shown instead an alternative screen is displayed, such as a Schrodinger's Cat logo is displayed together with a quote from Dumas' book ‘The Three Musketeers' where the title of Chapter 35 is All Cats are alike Gray in the Dark”.

The mobile software application of this clock system, may also guide the user to a more substantial webpage which simulates an electronic hardware product which embodies the clock system. The software app and web page may enable the user to configure the system to their own requirements and have a bespoke product device manufactured according to the user's requirements.
