.......................... 10 ~ Ir~~~"~CIe~Cti01'1 The InvisibleRoof TM, sometimes referred to as a CSD, (Convertible Safety Device), has been designed to save lives and prevent serious injury in the event of a catastrophic accident. In this accident, a car (or other mode of transportation without a roof} flips or rolls over. This CSD will instantly deploy (much like an airbag) to provide a physical barrier between the ground and the occupants. The CSD can be adapted to be installed in any vehicle that does not have a permanent roof.
For example:
Boats (High Speed & Other) All Terrain irehicles(ATYaJ
CTolf Carts Trucks The premise of the installation of the InvisibleRoof ~ is that it will be designed into the original vehicle. To maintain the structural integrity of the system, it will not be offered as an optional retrofit.
2 Artist's Conception Please see the attachment.
3 Operational Overview lnvisibleRoof'z''' is envisaged as twin actuators, joined by a cross-brace, (located in the rear of the car body} that operate pneumatically. Sensors will constantly determine the tilt of the vehicle, and when that tilt exceeds 45°
(degrees), the actuators will be driven out of the car body to a predetermined length. They will lock in place and as the car rolls or flips the cross-brace between these 'arms' will act as a roll cage, preventing the car body from coming in contact with the surface.
3.1 ~evice Satet~
Accidental deployment of the InvisibleRoof TM is unlikely. This is because thc;
electronic sensors and levelers control the actuator's functions.
As even the steepest hills only approach a grade of 15-2t!° (degrees), deployment happening under normal driving conditions is nat considered possible. There are other circumstances in which a vehicle might be tilted. (e.g. towing etc.) Again, the system will not deploy because those angles also do not approach the 45° threshold.
The system is set in the READY mode at all times.
3.2 Ailaintenance The InvisibleRoof TM does not require scheduled or on-going maintenance.
i~lhen it is installed, it must be calibrated to (+/-) 0-I° of 45°. It will not require further calibration unless the device itself activates.
3.3 ti~aterials Materials will be of the highest quality, and will be selected at the time of design.
3.4 Design Drawings InvisibleRoof TM assembly drawings are to be included with this document.
Detailed drawings are required and will be produced for both. manufacture and installation.
3.5 Weight Total weight of the system is a consideration in its design and implementatioua. ~nce materials and components have been selected, this will be determined and changes will be made if required.
4 Design 4.1 ~la~ne InvisibleRoof T~, or generically known as a 'Convertible Scafe~y Device'.
(CSD) 4.~ location This safety system will be installed behind the rear seat of the convertible or other mobile system.
4.3 Concept To provide a strong and invisible safety device that will deploy instantly as a roll cage on vehicles without a roof in the event of a catastrophic accident.
POWeP
Its electronic components and sensors will be powered by the vehicle's battery. The actuators will be driven by pneumatics.
4.5 Dimension The overall length and size of the aetuatc~r shafts will be chosen based on the dimensions (height, width and weight) of the vehicle on which they are to be installed.
4.6 ~peration ~ The device will be activated within a fraction of a second after the vehicle is tilted on any axis to greater than 45°.
~ In order to detect this tilt, an electronic leveler will continuously monitor the vehicle's 'balance'. It will be installed as close to the centre point of the vehicle as possible.
~.7 Process Vehicle tilts suddenly to an angle greater than 45°. (-t-/-) 0-1°
~ The leveler diagnoses this condition and sends a signal to the solenoid.
~ The solenoid activates both actuators, which causes them to extend and lock in their optimum position.
4.8 Actuators Actuators are pneumatically operated. They will be chosen independently for each vehicle type.
4..9 Solenoid The appropriate solenoid will be selected for the system.
5 Angle Sensing Rollover 111!'arning and Proteotson System This is a vehicle angle sensing system that warns the driver about possible rollover situations and takes protective measures in case of a rollover to reduce injury.
The system comprises of a dual-axis inclination measurement unit located at the center of gravity of vehicle which issues a warning signal as soon as the roll or pitch angles of the vehicle exceed a pre-specified amount with respect to the road.
This signal is then run through a decision making and electronic unit. The electronics, enabled once the engine is on, will send out warning signals to the driver (buzz, light, etc) if the vehicle angle is approaching certain limits (e.g. X35 degrees) or the rate of change of this angle is too much.
As soon as the X45 degrees limit is violated (where the vehicle rollover is a possibility), the electronic circuits will activate a pair of fast-action safety jacks at the rear ofthe vehicle. The released jacks which can be either pneumatic or electromechanical actuators will provide protection for passengers by absorbing the impact and weight of the rolled vehicle.

There are quite a few single- and mufti-axis inclinometers on the market that can be used to measure the instantaneous angle of the vehicle.
In addition to the inclinometers commercially available, the following simple mechanism can detect the roll and/or pitch angles going beyond the X45 degree limit.
It consists of a pendulum, a ball joint and a metallic semi-sphere. The ball joint connecting the pendulum to the semi-sphere allows free movements of the pendulum.
As a result, the pendulum will always be aligned witlx the gravity vector.
The pendulum is made electrically insulated from the metallic semi-sphere while its tip is electrically wired to the semi-sphere. As soon as the inclination angle of the vehicle chassis and the semi-sphere secured to it exceeds X45 degrees in any direction, as shown in the following picture, the pendulum tip makes contact with the semi-sphere, building a short circuit and consequently activating the safety jacks.

Moreover, it is possible to incorporate a time-integrating logic into the electronic unit that will differentiate between a momentary short circuit (very likely due to jerks, road bumps, etc) and a rather sustained contact (for example, of 0.1-0.2 sec duration; most likely due to a large tilt angle of the vehicle), in order to minimize the chances of an erroneous activation of the safety mechanisms.
More specifically, energy storage devices (such as capacitors) can be used to build a circuit that outputs the time integration of the input waveforan, thus slowing down the rate of changes and suppressing unnecessary fluctuations at the output.

6 5.2 Safety Jacks In case of a rollover, a pair of safety jacks is released to ensure safety of passengers.
Again there is a small window of time during which the jacks should be fully extended. These jacks can be implemented via an air pressure-based (pneumatic) approach or an electromechanical approach.
5.2.1. Pneumatic jacks The safety jacks can be in the form of air cylinders that will extend once the electronic unit activates either an air tank's (solenoid) valve or an air compressor. In the case of the air tank, the valve is normally closed and is fully opened once an input voltage is applied to it. In either case, the air pressure supplied by the compressed air tank or the compressor will extend the air cylinders quickly. A locking mechanism, (description follows), can be used to keep the jacks fully extended when they face the weight of the rolled vehicle, even if the air pressure has been depleted.
5.2.2. Electromechanical jacks Another method for implementing these fast-action jacks is to use the following 4-bar linkage assembly. This mechanism converts the rotational motion of an electric motor to the linear motion of a bar. This mechanism has the advantage that it can be put to test from time to time, while this may not be cost-effective if a one-time-use filled air tank is being used to do the same task. Similar to 13.1, a locking device is used to keep the bar fully extended as it faces the weight of the rolled vehicle.

A view of a possible arrangement for a locking device is ihustrated on the next page.
This mechanism is very similar to a door lock and involves a latch proximate to the main shaft. (Le. the air cylinder shaft or the end bar of the linkage assembly. This depends on the choice of actuator). When the main shaft moves to the left, the latch moves the two tongues away and passes through them. However, the shaft is not able to move in the reverse direction, meaning that this mechanism will lock the shaft in its extended mode.
Again there is a small window of time during which the jacks should be fully extended. These jacks can be implemented via an air pressure-based (pneumatic) approach or an electromechanical approach.

7 5a3 Eiectr~nie Unit Based on the input/output characteristics of the inclination meter and the safety jacks, the electronic unit has to be designed. For example, if the inclination meter outputs an analog voltage between 0 to 10 V in proportion to tFne tilt angle, and if supplying 24 volts can activate the pneumatic or electromechanical actuator, the block diagram of the electronic unit will be as seen on the following page:
