General Questions
How does MOCA stay up on the ceiling?
Magnetism from permanent rare earth magnets within the carriers attract to the special ferromagnetic (iron-based) ceiling surface with tremendous magnetic force to safely support objects and people.
How is MOCA powered to hold itself up?
MOCA requires no power to stay up and provide support. High-energy permanent magnets permanently couple the overhead carrier to the special iron-clad ceiling panels
Why doesn’t MOCA need power to stay up?
MOCA uses permanent magnets because their magnetism is ‘always on’; they generate their own persistent magnetic field, unlike electromagnets, which require an electric current to generate a magnetic field.
How much weight can MOCA support?
Prototype units have been built and tested to safely support an operating load of 500 lb (227 kg) and 1000 lb (454 kg) respectively, with each having an ultimate load capacity 250% greater than the operating load.
How is MOCA able to move?
The carrier is riding on hundreds of recirculating non-metallic bearing balls between itself and the ceiling surface. These balls reduce the moving resistance to near zero and allow it to move in any direction at any time.
How is MOCA powered to move, travel, or lift?
The carriers need not be powered to be permanently supported and freely movable by the user. However, they could be battery-powered for motor-driven travel, lifting, and other powered functions, much as robotic vacuum cleaners can move about. Charging stations can be positioned out of the way and/or incorporated into special ceiling tiles.
How far can you travel on a MOCA ceiling?
There is no span limit. Travel is possible everywhere the MOCA ceiling is installed, even with other separately supported friends moving along beside you as you travel.
How can MOCA move through doorways?
In new construction and room renovations the door header is simply removed so that the ceiling can continue uninterrupted into the adjacent room. New full height doors or door extensions can be used to heighten original doors as well. Additionally, a variety of viable alternate methods are being developed for unaided free movement through doorways, with the inclusion of sound and air separation between rooms before and after passage
How fast can MOCA move?
MOCA carriers could travel as fast as you can walk or jog. Faster speeds are possible but not presently an objective. Speed limiting may also be desirable for safety and could be provided by several reliable methods.
How much sound does MOCA make in operation?
A traveling carrier creates some swooshing sound without powered drive, but even with powered travel no barriers to producing relatively quiet movement are expected.
Can MOCA be locked in any position?
A very effective magnetic braking system has been built and tested that even increases the holding strength while in use.
Can MOCA carry other items along with the patient?
It is expected that some users may require oxygen or other gases, IVs, or the administration of fluids and medications even while partially or fully supported by MOCA. If greater load capacity is required to move the extras with a patient, then a second carrier can be hitched to the patient’s carrier to move in unison wherever they go.
Can MOCA support multiple carrier users in the same space?
Not only can separate users be close enough to touch one another, but they can move when close or hold hands as they move, sit next to each other, etc. Caregivers could also be supported separately, but close enough to help support a patient while physically assisting them and also being safely supported themselves to prevent their own injury. The social qualities of MOCA for multiple users in the same space can be dramatic and exceptional by comparison with other products.
How can MOCA help and protect caregivers?
MOCA can provide multiple movable support points from the ceiling for the patients they physically support and the caregivers themselves. This methodology can prevent excess strain on the caregivers while always preventing fall injuries to all users. Where optimum safe handling procedures are a requirement for patients and caregivers, MOCA could fulfill the needs.
Can MOCA be used outdoors?
MOCA can be used outdoors, but it must be operated under an overhead support frame that is capable of providing a watershed and the load support required for its intended use. This could be a covered patio, a covered walkway between buildings, a covered carport, garage, covered loading area, or a pole barn type constructed space.
Can MOCA be used over swimming pools?
MOCA could certainly be installed over indoor swimming pools, even Olympic-size swimming pools, and the surrounding areas and rooms around them. For outdoor pools, see (Can MOCA be used outdoors?). MOCA Installation over swimming pools would vastly increase the pool’s utilization, safety, variety of therapies, training routines, and play activities.
Can MOCA be used in conjunction with existing track systems?
The use of MOCA in conjunction with existing track systems has been considered and has been determined to be entirely feasible. It may, however, require some unique adaptations to different track systems.
Can MOCA do everything existing overhead track support products can do?
Yes, and in terms of its free, limitless multidirectional conveyance, load capacity, ease of use, overall utility for a multiplicity of uses, and the support of numerous independent simultaneous users, no existing products compare.
Is MOCA expensive and how does it compare with other existing systems?
Analysis indicates that the system cost is comparable to or less than conventional track-based systems depending on the span of use.
Carrier Questions
Can carriers include a powered lift or hoist?
They would most likely either incorporate a hoist into the carrier itself, or the carrier could support a separate hoist.
Can the carrier provide illumination as well?
Battery powered illumination will be a simple and useful enhancement that could be easily incorporated.
How can the carrier be removed and reinstalled on the ceiling?
Special detaching devices can remove the carrier from the ceiling at any location; however, they require special tools to prevent damage to the components. Typically, a non-attracting panel is installed behind removable stop-curbing to prevent accidental movement onto the panel, creating a removal station at a convenient ceiling location, such as a corner. When the curbing is removed, the carrier can be moved onto the non-attracting panel, where the attraction to the ceiling will cease, and the carrier can be lowered away by hand. This also becomes the location where a carrier can be easily loaded onto the ceiling as well.
Ceiling Questions
Is it difficult to install the ceiling?
Installation is relatively simple but different from conventional overhead track support systems. It is very similar in form to conventional suspended ceiling systems, only with much stronger structurally rated components and anchoring points to the structure above. The MOCA ceiling can be installed in very limited spans; however, its greatest benefits are realized from an expansive installation. Doing so benefits everyone in those spaces needing safe mobility while also supporting many objects that can be suspended from the ceiling. This added benefit frees up and unencumbers the floor space for people.
How heavy are the ceiling panels?
MOCA Panels are currently 24 in. (61 cm.) square or 24 in. (61 cm.) x 48 in. (122 cm.) rectangles. Depending on size, they typically weigh 5 to 6 lbs. or (2.3 to 2.8 kg.) per sq. ft. Even with their relative lightness, installation-assist devices can be utilized to assist their installation.
Can the ceiling be colored or painted?
Tests indicate that the feasibility of continuous movement of MOCA carriers traveling over certain colored paints and coatings is entirely workable; in fact, special printable laminated films can be applied to panels to provide colors and patterns that simulate textures and provide anesthetic consistency with a space’s décor and needs to include signage.
Will the ceiling get marked from its use?
The carrier is riding against the ceiling surface on hundreds of non-metallic non-marking balls. The quantity of bearing balls between the surfaces reduces the contact pressure per ball so low that it is measured in ounces (grams), not enough to mark the ceiling.
How will MOCA keep from interfering with other ceiling-mounted objects?
Suspended ceilings typically have standard-sized drop-in fixtures for lighting, ventilation, alarms, etc. These can be employed as conventionally used, only with added low-height curbing surrounding them to prevent support carriers from traveling into them. Consideration should be given to the location of fixtures during installation to optimize freedom of support carrier movement.
Safety Questions
How safely can MOCA hold people and/or objects up?
Present carrier designs have a holding force 2½ times greater than their operating load capacity. This is a medical industry standard; however, the safety factor could be easily increased with simple design changes if necessary.
What overload protection does MOCA have?
Additional safety options can be incorporated to provide visual and audible alarms if safe loads are exceeded. Overload belay-type lowering units can be employed to fully support safe loads and also safely lower excess loads.
Advanced Features Under Development
Can MOCA be voice controlled by the patient?
That feature has been considered and the necessary componetry is available to allow its incorporation into the carrier units along with numerous additional electronic and computer-based systems.
Can MOCA be used over stairs?
An effective and relatively simple method of utilizing MOCA over stairs has been conceived and is in line for further planned engineering development.
Can special ceiling panels for lights and ventilation be made that a carrier can travel over?
Ultimately, we expect to have them available. Design work is already in progress.
Other Potential Markets
Can MOCA be used for supporting animals?
MOCA can also be utilized to support animals indoors or outdoors in properly prepared spaces. If used outdoors, MOCA must be operated under an overhead support frame capable of providing a watershed and the load support required for its intended use or a pole barn-type constructed space.
Can MOCA become an overhead robotic carrier system for industry?
It could, and much consideration has been given to that concept. We are currently working on this as a near future development.
What markets can MOCA be utilized in?
MOCA can be utilized in numerous markets including but not limited to:
- Health Tech
- Smart Houses
- AR/VR
- Distribution
- Manufacturing
- And many other potential markets
Technical Questions
How much magnetic holding force does MOCA have?
The technology has no design load limits. The system could be scaled for any load capacity. Tested units have had up to a 1,000 lb (454 kg) operating load with an ultimate supported load of 2,600 lb (1,180 kg).
How long will the magnets last?
The magnetic carriers employ numerous rare-earth-magnets with an expected life of over 100 years. It is also expected that periodic scheduled inspection and testing will be recommended and/or required for system operational certification, much like elevators and other human-supporting equipment.
How long will the non-metallic balls last?
The non-metallic bearing balls between the carrier and ceiling surface are tough and resilient. They have been tested under load for over 60 mi (96 kg) of use resulting in no measurable wear. We expect many years of use before requiring their easy replacement.
Do the magnets cause problems for people and/or instruments in the area?
MOCA creates no negative effects resulting from the presence of its supporting magnets. No externally powered electromagnetism is employed, which can emit radio waves that could interfere with radio wave-based instruments and communications. MOCA’s magnetic fields are permanent localized fields internally generated, and these magnetic fields are tightly contained between the carriers and the ceiling area directly above them. No magnetism can leave the small coupling area between them. Although the magnetic fields are confined in normal use, they are powerful; therefore, the carriers require trained and qualified personnel to remove or modify them or any system parts.
Can MOCA be designed to carry greater loads?
Multiple carriers can easily be used to support heavier objects. Alternatively, several carriers can be joined on a single frame to support greater loads.
In theory, there is no limit beyond the supporting structure behind the MOCA ceiling panels. The magnetic attraction can be increased, and the magnetically attractive ceiling area can be broadened sufficiently to meet the specific engineered needs of any system.
Why are permanent magnets permanent?
A permanent magnet is called a permanent magnet because its magnetism is “always on.” It generates its own persistent magnetic field, unlike an electromagnet which is made from a coil of wire wrapped around a steel core and requires an electric current to generate a magnetic field.
What creates permanent magnets?
Whether natural or fabricated, permanent magnets are caused by a magnetic field passing through the magnet’s material as it cools from a melted state. This causes the atoms in the substance to align and amplify their individual atomic fields into a single large magnetic field that we can use permanently.
Is the MOCA ceiling also magnetic?
Sometimes, but only directly above the MOCA carriers.
The ceiling is made from iron-based steel, which means it is ferromagnetic but not magnetic until it is close to a magnetic field. A close magnetic field from a MOCA carrier will temporarily cause it to become magnetic but with an opposite magnetic polarity. Thus, it attracts the carrier during its closeness and lets go of its magnetic attraction once the carrier has moved away.
