     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates generally to a wireless control system and method for use thereof, and more specifically to a wireless control system for a mobile hydraulic transforming stage system. 
         [0004]    2. Description of the Related Art 
         [0005]    Mobile performance stages are commonly used for temporary venues, performances, or rallies. Typical mobile performance stages must be assembled on site. Modern mobile stages may come in the form of a trailer, wherein the mobile stage is collapsible to a compact and mobile unit. 
         [0006]    Mobile stages are often an economical alternative to erecting a permanent stage at a site. The typical reasons for electing to use a mobile stage include temporary use, cost, and reliability. Cutting the costs of using a mobile stage provides additional incentive for using a mobile stage. The simplest way to cut costs would be to reduce the number of persons and steps required to setup and operate the stage. Costs are also saved when the owner of a mobile stage knows the stage will last. These cost savings can be passed on to customers, increasing the incentive to use one mobile stage over another. 
         [0007]    What is needed is a highly transportable stage system with a controller to allow the stage to be transformed from a compact/transportation position to a functional stage position and back. 
         [0008]    Heretofore there has not been available a system or method for a mobile hydraulic stage with the advantages and features of the present invention. 
       BRIEF SUMMARY OF THE INVENTION 
       [0009]    The present invention generally provides a deployable mobile stage system including a remote mobile computing device which acts as a controller. The mobile computing device can be any basic personal computing device such as a smart phone, tablet computer, laptop, smart watch (or other smart accessory) or a proprietary control unit. The mobile computing device interfaces wirelessly with a receiver unit located on the mobile stage. The receiver unit relays commands to a hydraulic system which then commands various valves to open and/or close, thereby transforming the mobile stage from a first, deployed position to a second, transport position or back.

A computing device could be represented by a desktop personal computer, a laptop computer, “smart” mobile phones, PDAs, tablets, smart watches, or other handheld computing devices. 
       II. Preferred Embodiment Mobile Stage Control System  2   
       [0016]    Previously, the operation of a mobile hydraulic stage has required a user to manipulate the stage set-up using either a wired or wireless control pack. This can be cumbersome to the user as these packs are often large and inconvenient to carry around. However, modern mobile devices such as cell phones, tablets, laptops and wearable technology have wireless technology built into them and are commonplace in today&#39;s society. Being able to use an application installed onto one of these small, mobile “smart” devices to operate a mobile hydraulic stage provides a user with a much more convenient process when setting up or taking down the stage. These operations involve walking, climbing and otherwise moving around the stage performing inspections to ensure that the stage is properly deployed and that it properly returns to a pre-set-up state. Using a small “smart” wireless device to control the stage during these procedures would expedite the process and allow the operator freedom of motion without being restrained by physical wires or cumbersome control units. 
         [0017]    Bluetooth and Wi-Fi are two commonly present forms of wireless technology which could be used to interface from the control application to the stage, however, any wireless technology available (now or in the future) could be used instead. 
         [0018]    Referring to the figures in more detail,  FIG. 1  shows a mobile stage control system  2  generally including a collapsible mobile stage  4  which can transform from a first, deployed position ( FIG. 2 ) to a second, transport position ( FIG. 3 ), a mobile computing device  6 , a receiver  16 , and a mobile stage hydraulic system  26 . Generally, the mobile computing device  6  communicates wirelessly with the receiver  16  located in proximity with the mobile stage  4  and mobile stage hydraulic system  26 . 
         [0019]    The wireless computing device  6 , which could be a proprietary device or an existing personal computing device such as a smart phone, tablet computer, or laptop computer, includes an antenna  8  for wirelessly communicating with the receiver  16 , a CPU  10  for handling application data and processing commands, data storage  12  for storing a software application  14  used to control the hydraulic system  26  and to transform the stage  4 . 
         [0020]    Similarly, the receiver  16  includes an antenna  18  for receiving commands sent by the wireless computing device  6 , a CPU  20  for processing signals received by the antenna  18  and transmitting commands to the mobile stage hydraulic system  26 , data storage  22  for storing data and software relevant to the control of the mobile stage  4 , and a signal amplifier/translator  24  necessary for communicating commands from the mobile computing device  6  to the mobile stage hydraulic system  26  components. 
         [0021]    The receiver  16  may receive other data, such as external, third-party data from an external data source  21 . This data could include weather data, wind speed data, temperature data, or other data relevant to how the receiver  16  CPU  20  would handle commands received from the mobile device  6  and transfer those commands onto the hydraulic system  26 . As an example, if inclement weather is detected the CPU  20  may indicate a warning to the users either via the mobile device  6  or some other method, and may automatically withdraw some or all stage elements, such as lowering some of the side walls to prevent wind damage. These variables could be considered external control variables. 
         [0022]    The mobile stage hydraulic system  26  is made of up generally two parts: the hydraulic fluid supply and return system  28  and the electro-mechanical hydraulic valve bank  30 . The fluid supply/return system  28  generally includes the pump  32  for the hydraulic fluid, a power unit  34  (e.g. gasoline, diesel, or electric motor), and a fluid reservoir  36  for storing the hydraulic fluid. 
         [0023]    The electro-mechanical hydraulic valve bank  30  includes a number of valves corresponding with respective components of the mobile stage  4  as shown in  FIG. 2 . A roof  1 A valve  38  connects to and controls a roof  1 A panel  62  which hinges away from the static roof panel  82 , and a similar roof  1 B valve  40  connects to and controls a roof  1 B panel  64  which again hinges away from the central static roof panel  82 , as depicted in  FIG. 2 . This forms a covering for the floor of the stage. 
         [0024]    A floor  1 A valve  42  is connected to and controls a floor  1 A panel  66  which hinges away from a central static floor panel  84 . Similarly a floor  1 B valve  44  is connected to and controls a floor  1 B panel  68  which hinges the opposite direction away from the static central floor panel  84 . This forms the base of the stage. 
         [0025]    Four outrigger valves, outrigger # 1   46 ; outrigger # 2   48 ; outrigger # 3   50 ; and outrigger # 4   52 , correspond with and connect and control respective outrigger # 1   70 ; outrigger # 2   72 ; outrigger # 3   74 ; and outrigger # 4   76  to raise and lower the stage floor from the ground. 
         [0026]    Two mast valves, mast A  54  and mast B  56  respectively connect to and control a pair of masts, mast A  78  and mast B  80 , which raise and lower the sides of the stage, thereby raising the roof panels  62 ,  64 ,  82  away from the floor panels  66 ,  68 ,  84 . 
         [0027]    The various valves  38 - 56  receive hydraulic fluid through a selector/supply valve  58  and dispense hydraulic fluid out to the various respective components of the mobile stage  4  through an outlet  60  to the various hydraulic cylinders. 
         [0028]      FIG. 3  shows the mobile stage  4  in a compact, transport position. It can be mounted onto a trailer or otherwise be affixed with wheels  86  and a tow bar  88  for towing the stage from one location to another, where it can then be redeployed using the control system as described above. 
         [0029]    It is to be understood that while certain embodiments and/or aspects of the invention have been shown and described, the invention is not limited thereto and encompasses various other embodiments and aspects.
