With the connection of the charging controller between the solar panels 16, external power input, such as a wall outlet or the connected mobile device, and the batteries 4, charging power can consistently be applied to the batteries 4 in accordance with predetermined power schemes.
For example, the charging controller can identify the presence of charging power coming from one or more solar panels 16 and discontinue external power charging of the batteries 4 while directing battery charging from the solar panels. Conversely, the charging controller may be capable of regulating charging power concurrently from the external power source and the solar panels 16 in certain instances, such as if the batteries 4 are very low or the solar panels 16 are not providing consistent power supply.
The charging controller can further be configured to supply a predetermined amount of power to the mobile device controller via a composite of power supplied from the batteries 4 and external power supply. As such, the charging controller can dictate the function of the solar panels 16 and external power source as secondary or primary power sources to constantly recharge the rechargeable batteries 4 as the power level decreases, regardless of external conditions.
Turning to FIG. 3, the bottom casing 2 is shown, as designed in accordance with various embodiments, to be a shell with an elongated “U” shape similar to the top casing 1. The bottom casing 2 has a left vertical segment, a right vertical segment, and a horizontal segment. The left vertical segment and the right vertical segment have a unique design which fits firmly to the user's palms. Such unique design provides secure connection between a user and the casings 1 and 2, which allows for efficient and comfortable handling and engagement of the various joysticks, buttons, and pads. It should be noted that the unique design of the bottom casing 2 can be characterized as rounded protrusions shaped to fit the palm of a user's hand to position the fingers of a user in efficient position to engage the various controls of the mobile device controller.
The bottom casing 2 may be made out of any kind of material that may be similar or dissimilar from the material of the top casing 1, but is a high strength plastic in some embodiments to minimize the weight of the bottom casing 2. Comfort and dexterity of a user may be enhanced with the addition of material to predetermined portions of the top 1 and bottom casing 2. For example, increased friction regions, such as rubber inserts and grooves formed in the casing material, may be positioned proximal the various controls to increase dexterity during strenuous gameplay.
The bottom casing 2 may be configured with a stand or means for connecting a stand to allow the controller and attached mobile device to be erect without contact with the user. Such a stand may be connected to the back side of the bottom casing 2 and positioned parallel to the bottom casing 2 to prevent any obstructions from obscuring the display of the mobile device. Various embodiments configure the stand to be housed within the bottom casing 2 and capable of being extended to provide a variety of angular positions for the display of the attached mobile device.
FIGS. 3 and 4 respectively show how the bottom casing 2 can provide one or more trigger buttons 21, a plurality of screw holes 23, a headphone jack 24, and a universal serial bus port (USB port) 25. A plurality of trigger buttons 21 can be positioned to be aligned with the right and left vertical portions of the top casing 1 and comprise a top left button 211, a bottom left button 212, a top right button 213, and a bottom right button 214. Both top left buttons 211 and the top right button 213 have a flat top surface, but can be shaped in any manner, such as convex, to provide predetermined engagement with a user's fingers. Each of the trigger buttons 211, 212, 213, and 214 can be made from similar or dissimilar materials, such as high strength plastic, and electronically connected to the circuitry board 3 to perform assigned commands upon activation.
A plurality of screw holes 23 are positioned at predetermined positions in the bottom casing to allow secure physical connection between the top 1 and bottom 2 casing. One or more fasteners, such as rivets and screws, may occupy the screw holes 23 to adhere the casings 1 and 2 for durable longevity. The headphone jack 24 and the universal serial bus port (USB port) 25 are laterally positioned around the bottom casing 2 and can be connect an external device to the circuitry board 3 when the external headphone plug is inserted into the headphone jack 24 or a properly sized serial connector is inserted into the USB port 25.
The USB port 25 may be used to provide power via an external UBS power cord and data storage via an external data storage device. The USB port 25 may be configured to provide two-way communication to and from the attached mobile device. Such voice communication can be adapted to provide voice control of various features of the mobile device and mobile device controller, such as the start button 112 and select button 111.
The mobile device controller may further comprise a control application which can be downloaded into the mobile device whether the mobile device is physically connected to the mobile device controller, or not. That is, the mobile device controller may have software, firmware, and applications stored on an internal data storage component connected to the circuitry board 3 that can be transferred to a mobile device through both a physical connection with an interface, such as a serial connection shown in FIG. 6, or through a wireless connection, such as a Bluetooth connection. Hence, a user has at least two connecting options with mobile devices as the mobile device can be physically attached to the mobile device controller via a rigid electrical connector and through a wireless connection, either individually or concurrently.
The variety of connections may be utilized to provide security features to the mobile device controller. For example, a secure Bluetooth connection or wired serial connection with verified security key may be mandated before wired or wireless access to an attached mobile device is allowed. That is, security can be required either via wired or wireless means before data or control can be passed from controller to the mobile device. Such security features can allow for confident passage of secure information, such as billing data, personal data, and passwords, from the mobile device controller to the mobile device. Likewise, such security features can effectively lock the mobile device controller from being used by unintended users.
Various embodiments of the mobile device controller configure the distance between the left and right segments of the top casing 1 to conform to the dimensions of a mobile computing device, such as a tablet computer, in a horizontal or vertical orientation. As displayed by the horizontal orientation of a tablet computer in FIG. 6, the mobile device controller can be designed to be viewed at arm's length so that the mobile device display is wider than a predetermined distance between a user's eyes. Such width may necessitate two hands of a user to grip and operate the various controls of the mobile device controller. With the horizontal position of the mobile device, three-dimensional operation of the display of the mobile device can be performed with proper stereoscopic depth of field, with or without three-dimensional glasses being worn by the user.
FIG. 7 provides a block representation of a portion of an example mobile device controller in accordance with some embodiments. While not limited to any particular capabilities, components, or size, the circuitry board 3 connects all of the input and the output data from the mobile device controller. The circuitry board 3 may comprise at least one electrolytic capacitor 31, capacitor 32, switch 33, resistor 34, variable resistor 35, crystal resonator 36, chip 37, IR signal controller 38, charge controller 39, accelerometer 40, and oscillator 41.
According to some embodiments, one or more accelerometers 40 can be positioned at separate regions of the mobile device controller to accurately sense motion, direction, and acceleration to be used to control digital objects on the attached mobile device. A plurality of accelerometers 40 can be calibrated to correspond to portions of a user's body, such as the user's head, to allow realistic motion of a digital object based on motion of the user's body. Such calibration may further utilize predictive filters with or without external hardware mounted to the user's body, such as a headband, glove, or boot, to define motion of the user in the X, Y, and Z planes, respectively.
One or more electrolytic capacitors 31 can be electronically connected to various other components, like a capacitor 32, resistor 34, and charge controller 39, while the crystal resonator 36 is electronically connected to a plurality of capacitors 32. Similarly, the crystal resonator 36, the resistor 34, and variable resistor 35 may be interconnected with each other and with one or more IC chips IC chips 37 and switches 33. The IR signal controller 38 may be electronically connected to the circuitry board 3 while being connected to at least one infrared eye and radio frequency receiver, which provides an IR signal that can be transmitted from afar to provide wireless control of the mobile device controller and, in turn, the attached mobile device.
The variety of electrical components may provide the circuitry board 3 with a wake up circuit 42 that may or may not include a low power oscillator 41 that allows the circuit to transition from a powered down stage to an activated stage, or vice versa, upon connection, either wired or wireless, to a mobile device. As such, the wake up circuit 42 can conserve power in the batteries 4 by sensing the lack of connection to a mobile device. In some embodiments, the wake up circuit is implemented as part of the charge controller and/or an accelerometer 40 so that battery power and activation of the mobile device controller is seamless with connection and movement of the attached mobile device.
With the various structural and operational configurations of the mobile device controller, sophisticated control, connections, and power management can be combined into an ergonomically designed device. The configuration of the various buttons, joysticks, triggers, and directional pads can allow a user to comfortably engage in virtually any activity provided by an attached mobile device from playing a game to watching a video.
