Referring to
As used herein, an electronic safety device 102 includes but is not limited to lighting devices such as emergency or warning lighting (e.g., a light bar) and area lighting (e.g., scene lights) and/or a control head for audio devices such as an emergency or warning sound generator, a siren, and a public address (PA) system. As used herein, an electronic safety device 102 includes lighting and sound-based warning products used by professionals in emergency response, utility, service fleet, and industrial settings. As used herein, an electronic safety device 102 includes products that enhance safety for law enforcement officers, firemen and emergency medical technician (EMT) personnel, as well as all personnel in utility, transportation, and construction industries.
Such electronic safety devices 102 include but are not limited to a light bar and/or a siren. Such devices frequently have a processor 106 having the control port 104 configured for receiving digital signals for controlling the mode of operation of the device 102. For example, if the device 102 is a light bar, the digital signals control the mode of operation and particularly the light patterns produced by the light bar. As another example, if the device 102 is a siren, the digital signals control the mode of operation and particularly the sounds produced by the siren.
The system 100 includes a device such as a touch pad sensor 108 configured for detecting operator input 110, such as a gesture by the operator. A gesture includes any type of detectable movement or detectable touch (e.g., physical contact with a sensor) by the operator, such as the examples noted below in more detail. The movement or touch includes movement or touch by the operator or by a physical element (e.g., a stylus or glove) under an operator's control. The touch pad sensor 108 is configured to provide a signal, such as a gesture signal, corresponding to the operator input 110, the detected gesture corresponding to a mode of operation of the electronic safety device 102.
A control 112 is configured for receiving the signal from the touch pad sensor 108 and is configured to provide a corresponding control signal to be applied to the control port 104 of the electronic safety device 102 for controlling the mode of operation of the electronic safety device 102. The controller 112 may include a touch pad controller 114 and a master controller such as a processor 116 having an output port 118 for providing the control signals. For example, the touch sensor 108 and controller 114 may be a Microchip® projected capacitive touch controller model MTCH6301, or equivalent. Other types of pads and controllers may also be used.
The touch pad sensor 108 is configured to detect the gesture signals and is configured to convert the gesture signals into output signals indicative of the detected gesture. The processor 114 is configured to receive the output signals and to convert the output signals into the control signals for controlling the operation of electronic safety device 102.
Thus, the output port 118 of the controller 112 is configured to be connected to the control port 104 of the processor 106 of the light bar/siren device 102. It is also contemplated that the touch pad controller 114 and processor 116 may be a single processor or similar device for generating the control signals in response to the gesture signals.
Thus, the control 112 comprises a controller 114, 116 configured to detect the gesture signals indicative of the detected gesture, and configured to convert the gesture signals into the control signals for controlling the operation of the electronic safety device 102. As a result, the gesture and the control signals implement the mode of operation corresponding to the detected gesture.
As shown in
It is also contemplated that the system 100 may include an optional display 120 responsive to the controller 112 and configured to indicate a current status of the electronic safety device 102. As illustrated in
In one form, the display 120 may include a head up display configured to project an image on a surface of a vehicle for indicating the current status of the electronic safety device 102. For example, the head up display may provide a graphic image indicative of the mode of operation of the device 102 or an alpha-numeric message (e.g., “take-down” mode) to indicate to the operator the mode in which the device 102 is operating. In another form, or additionally, the display 120 may include an alpha-numeric display configured to present alpha-numeric characters indicating a current status of the electronic safety device 102.
In one form, the display 120 may include a graphical display configured to present a graphic illustrating the current status of an emergency warning device. For example, the graphical display may be an LCD panel presenting an active, real time image of the mode of operation of the light bar or presenting an image indicative of a sound being produced by the siren.
In one form, the display 120 may include a light source configured to indicate the current status of an emergency warning device. For example, the light source may be one or more incandescent or light-emitting diode (LED) lights which, when illuminated, provide an indication to the operator of the current status of the device 100. As a specific example as shown in
It is also contemplated that the system 100 may include an optional control element 124 connected to the controller 112 and configured to control the electronic safety device 102. As illustrated in
In one form, the control element 122 comprises a switch such as a toggle switch 202 illustrated in
In one form, the control element 122 comprises a button configured to control the electronic safety device 102. As an example, as shown in
In one form, the control element 122 comprises a rotatable element configured to control the electronic safety device 102. For example, as shown in
It is also contemplated that the system 100 may include an optional feedback device 124 connected to the controller 112 and configured to provide an indication to the operator in response to the detected gesture. As illustrated in
In one form, the feedback device 124 comprises an audible sound generator including one or more of a speaker configured to generate sounds indicative of the detected gestures wherein different gestures correspond to different sounds; a solenoid configured to generate a sound (e.g., a click) or a vibration indicative of the detected gesture; and/or a voice generator configured to provide an audible voice indicative of the mode of operation corresponding to each detected gesture.
In one form, the feedback device 124 comprises an visual signal generator including one or more of a head up display projected on a surface of a vehicle configured to generating a display indicative of the detected gesture; an alpha-numeric display configured to generate an alpha-numeric display indicative of the detected gesture wherein different gestures correspond to different alpha-numeric displays; a graphical display configured to provide a graphic indicative of the detected gesture wherein different gestures correspond to different graphics; and/or a light source selectively configured to generate a light signal indicative of the detected gesture wherein different gestures correspond to different light signals. For example, an LED may be located in a vehicle and the controller 112 would illuminate the LED whenever a valid gesture is detected.
In one form, the feedback device 124 comprises a tactile signal generator including one or more of a solenoid configured to generate a movement palpable on the touch pad sensor 108 and indicative of the detected gesture; and/or a vibrating device configured to generate a vibration palpable on the touch pad sensor 108 and indicative of the detected gesture.
In one form, the touch pad sensor 108 is part of a control head or panel 126. As illustrated in
In one form, it is contemplated that the system 100 is configured to be connected to a vehicle device 128 of a vehicle for controlling the vehicle device 128. The controller 112 is configured to detect the gesture signals from the touch pad sensor 108 and is configured to convert the gesture signals into control signals for controlling the operation of the vehicle device 128. Thus, the control signals implement a mode of operation of the vehicle device which corresponds to the detected gesture. For example, the vehicle device 128 may be one or more of a lock (gun, door, K9 door, trunk); a light; an ignition element; a back-up audio warning device (e.g., a beeper), and an accessory (e.g., radar, windshield wipers).
Each detected gesture corresponds to only one mode of operation of the electronic safety device 102. For some gestures and their corresponding mode of operation, a first gesture in one direction initiates a mode operation and a second gesture in reverse or in the opposite direction discontinues the mode of operation. Thus, a particular detected first gesture corresponding to a particular mode causes the controller 112 to implement the corresponding particular mode when the particular mode is not being implemented at a time when the first gesture is detected by the touch pad sensor 108. Also, the particular detected second gesture corresponding to the particular mode causes the controller 112 to discontinue implementing the corresponding particular mode when the particular mode is being implemented at a time when the second gesture is detected by the touch pad sensor 108. As a specific example, refer to
In the above examples, a gesture could have different meanings depending on the mode of operation at the time of the gesture. For example, if the traffic directing light is OFF, a right swipe initiates a right pattern and a left swipe initiates a left pattern. If the traffic directing light is ON providing a right pattern, a right swipe is ignored and a left swipe discontinues the right pattern. If the traffic directing light is ON providing a left pattern, a right swipe discontinues the left pattern and a left swipe is ignored.
The above examples are relatively simple, single gestures. More complex gestures or two or more gestures within a preset period of time (e.g., 1 second) could also be assigned a particular meaning or mode of operation.
It is also contemplated that a gesture could be an overriding gesture which is always implemented independent of mode of operation the system at the time of the gesture. For example, a right swipe 5A1 would always mean that a traffic directing light would provide a right pattern and a left swipe 5A1 would always mean that a traffic directing light would provide a left pattern. Thus, if the traffic directing light is providing a right pattern and the touch pad sensor 108 detects a left swipe, the controller 112 overrides the right pattern and changes the traffic directing light to a left pattern. In this example a different gesture (e.g., up or down swipe) would turn off the traffic directing light.
The direction of the swipe (e.g., left, right, up, down, clockwise, counter-clockwise) is important and the same swipe in different directions would usually have a different meaning. Swipe and hold gestures are also contemplated. Single or multiple taps can also be assigned a particular meaning and mode. As shown in
Gestures can also be used for programming the controller 112. Thus, it is contemplated that the touch pad sensor 108 is configured to receive operational gestures for controlling the mode of operation of the electronic safety device 102 and configured to receive program gestures for programming a functionality of the controller 112. For example, the program gestures include a reset gesture for resetting the system 100 to a particular mode or default. Also, a password gesture can be defined for activating and deactivating the controller 112. In general, since the touch pad sensor 108 is an input device, any input that would be provided via a control head to an electronic safety device can be assigned a gesture. Even without a password, only trained operators would be able to use the system and method because untrained operators would not know the necessary gestures needed.
It is also contemplated that a control head may have two or more touch pads. For example, one touch pad may be used to control a light bar, a second touch pad could be used to control a siren and/or a third touch pad may be used to control some other feature or accessory of the vehicle.
Examples of various modes of operation of light bars and sirens which could be assigned a gesture include but are not limited to:
In one form, it is also contemplated that the system 100 is configured to control intensity such as brightness of a lighting device or a volume of an electronic safety device. For example, gestures applied to the touch pad controller 114 may be programmed to set the dimming (brightness) of a scene light. By sliding a finger along the touch pad sensor 108 and/or tapping the sensor 108, a scene light may be turned off completely, and/or its intensity adjusted from dim to full brilliance, or vice versa. A certain gesture such as a double or triple tapping of a certain number of fingers on the sensor 108 before sliding the finger on the sensor 108 would instruct the system 100 that the sliding gesture following the tapping is for controlling intensity of the scene light. Similarly, the system 100 could also be used as part of a siren controller to set the audio volume level of the siren, for controlling the PA and its volume and/or for controlling a radio rebroadcast feature and its volume. As a specific example, a system in one form would include an external scene light where the human interface is in the form of a gesture controller. In this example, a scene light would be a tripod mounted, battery operated light carried in a vehicle or by a person and deployed on the ground as needed for safety incidents and/or construction work.
Optionally, the controller 112 has a program port 132 configured to interface with an external device 130 for programming the control signals to be provided by the controller 112 to the electronic safety device 102 and/or for programming the control signals which correspond to the detected gestures. For example, the program port 132 can be a wired or wireless port for communicating with at least one of a computer, a phone and a switch.
One advantage of a touch pad system and method is that the system is easier, faster and safer to operate than existing control heads because the operator does not need to make visual contact with the touch pad system. Using a touch pad becomes more intuitive to the operator. In some forms, the touch pad system has no moving parts. The touch pad system is also more reliable and can easily be configured to be rugged and water resistant. It is contemplated that the system may be used in combination with a stylus or other devices handled by an operator such as gloves or other finger coverings which can be detected by a touch pad when contacting the touch pad.
