## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims the priority benefit of U.S. provisional application No. 62/041,219 filed Aug. 25, 2014 entitled “VLC Disposable VLC Detector,” the disclosure of which is hereby incorporated by reference.


BACKGROUND
Field of Invention
The present invention generally relates to wireless digital communication. More specifically, the present invention relates to disposable wireless receivers that can be connected to user devices to allow the user devices to receive wireless digital communications.
Description of the Related Art
Traditionally, the field of digital communications includes wired and wireless transfer of information. Digital communications may include direct communications in which information is transmitted from a sender device to a recipient device, and may also include “indirect” communications in which information is transmitted from a sender device, through one or more “intermediary” or “middleman” devices, and eventually to a recipient device.
One example of wired transfer includes data transmitted from a sender device to a recipient device using a Universal Serial Bus (USB) cable. Another example of a wired transfer includes data transmitted within a private Local Area Network (LAN) from a sender device to a router through a sender Ethernet cable, and from the router to a recipient device through a recipient Ethernet cable.
One example of wireless transfer includes data transmitted from a sender device to a recipient device using a Bluetooth protocol connection. Another example of a wired transfer includes data transmitted within a private Wireless Local Area Network (WLAN) from a sender device to a router through a wireless Wi-Fi connection, and from the router to a recipient device through a wireless Wi-Fi connection. Other examples of wireless transfer include Bluetooth communications, Visible Light Communications (VLC), radio wave communications, microwave communications, or sonic communications.
Different types of wireless communications may require different types of hardware receivers to receive. For example, Bluetooth communications require a Bluetooth receiver to receive, VLC communications require a photodetector to receive, radio wave communications require a radio wave receiver (e.g., antenna) to receive, microwave communications require a microwave receiver to receive, and sonic communications require a microphone to receive. Similarly, different types of wireless communications may require different types of hardware (e.g., a digital-to-analog converter or an analog-to-digital converter) or software to decode once received.
User devices, such as smartphone devices and tablet devices, are often built to be as small as possible. As a result, certain functionalities that might be included within larger machines are often left out of such user devices. For example, some user devices may lack the capability to receive particular types of wireless communications due to a lack of required hardware and/or software.
Thus, an alternate means for receiving wireless digital communications is needed.

For example, the disposable wireless receiver 115 may include a Wi-Fi connection module, a 3G/4G/LTE cellular connection module, a Bluetooth connection module, a Bluetooth low energy connection module, Bluetooth Smart connection module, a near field communication module, a radio wave communications module, a microwave communications module, a magnetic induction receiver, a magnetic resonance receiver, an electromagnetic radiation receiver module, a visible light communication (VLC) receiver module, a laser transmission receiver module, a microphone (e.g., audible sound receiver, ultrasonic receiver, infrasonic receiver) with or without noise cancelling features, or some combination thereof. The disposable wireless receiver 115 may include any number of sub-receivers. The disposable wireless receiver 115 may be configured to be able to receive and/or decode at least the wireless data 110 sent by the wireless transmitter 100.
The disposable wireless receiver 115 is connected to a user device 120. The connection between the disposable wireless receiver 115 and the user device 120 may be a physical or wired connection. For example, the disposable wireless receiver 115 may be connected to the user device 120 via a Universal Serial Bus (USB) cable, a lightning cable, a thunderbolt cable, an audio jack cable, a 30-pin cable, an HDMI cable, or another type of cable. Alternately, the disposable wireless receiver 115 may be connected to the user device 120 through a wireless connection, which may be short-range or long-range. For example, the disposable wireless receiver 115 may be connected to the user device 120 via a Bluetooth connection, through a magnetic induction connection, through a magnetic resonance connection, through a radio frequency identification (RFID) connection, or through a near-field-communication (NFC) connection.
The user device 120 may be a computer device 600, or may be a device with a subset of the components of the computer device 600. In particular, the user device 120 may include any type of processor (e.g., processor 610), any type of display (e.g., display 670), and/or any type of memory (e.g., memory 620, mass storage 630, portable storage 640, or any combination thereof). The memory of the fan device 110 may store, and the processor may execute, various instructions for executing software and associated user interfaces, such as various graphical user interfaces (GUIs). The user device 120 may be, for example, a smartphone, a tablet device, a laptop, a portable media player device, a portable video game console, or a portable e-book reader device.
The user device 120 may execute a variety of software elements at the processor of the user device 120, some of which may receive inputs through an input interface of the user device 120 (e.g., a touchscreen, a keyboard/keypad, a mouse, a joystick, a button, a microphone, a switch, a connector, or some combination thereof) and/or output visual data via a display and/or audio data via a speaker.
The user device 120 may in particular execute a wireless application 125 (e.g., see FIG. 4B), a wireless software 130 (e.g., see FIG. 4B), an operating system 135, and a set of wireless settings 140 which may be provided by wireless settings graphical user interface (GUI) 405 (e.g., see FIG. 4A).
The wireless transmitter 100 may in some cases be controller, managed, or monitored by an optional transmitter manager system 105. The transmitter manager system 105 may include one or more computer systems 600, which may include multiple computer systems 600 networked together (e.g., in a “LAN” local area network or a “WLAN” wireless local area network), multiple computer systems 600 distributed throughout the Internet, or some combination thereof. The transmitter manager system 105 may be connected to one or more secondary wired transmitters and/or wireless transmitters in addition to the wireless transmitter 100.
The wireless transmitter 100 may in some cases be associated with an event taking place at an event venue. For example, the wireless data 110 transmitted by the wireless transmitter 100 may include sports data for eventgoers of a sports event, or may include music data for eventgoers of a music concert. The wireless transmitter 100 may in such cases be associated with a variety of types of events, public or private, such as entertainment or cultural events that are presented at a theater, gymnasium, church, stadium, or other facility to a group of people. Such events include a wide variety of sporting events such as football (American and Global), baseball, basketball, soccer, ice hockey, lacrosse, rugby, cricket, tennis, track and field, golf, cycling, motor sports such as automobile or motorcycle racing, horse racing, Olympic games, and the like; cultural events such as concerts, music festivals, plays, or the opera, and the like; religious events; and more permanent exhibitions such as a museum, historic home, and the like. In such cases, the transmitter manager system 105 may be associated with the event or the event venue.
In an alternate embodiment (not shown), the wireless transmitter 110 may include a wired transmission mechanism, such as an Ethernet cable or a fiber optic cable or a modem cable. The disposable wireless receiver 115 may be connected to the wireless transmitter 110 through the wired transmission mechanism (e.g., via an Ethernet port, fiber optic port, or modem port of the disposable wireless receiver 115). This may serve as an alternate communication mechanism or as a primary communication mechanism. In this way, a portable user device 120 could be permitted to connect to a wired connection.
FIG. 2 illustrates an exemplary disposable wireless receiver. The disposable wireless receiver 115 of FIG. 2 may include a central bus 230, to which its other components may be directly or indirectly connected. In an alternate embodiment (not shown), the disposable wireless receiver 115 may be less centralized and may include one or more secondary busses, which may or may not then be connected to each other.
The disposable wireless receiver 115 of FIG. 2 includes receiver hardware 210, which may include hardware controller hardware (e.g., including data routing, frequency modulation, analog-to-digital converters, digital-to-analog converters, filters, or some combination thereof) as well as one or more particular receiver components 205 that are specific to receiving a particular type of communication, such as antennas (e.g., for receiving radio wave or microwave or cellular or Bluetooth or Wi-Fi communications), photodetectors (e.g., for receiving VLC communications or infrared or ultraviolet communications), microphones (e.g., for receiving audible, ultrasonic, or infrasonic audio-based communications), electromagnets or magnetic coils (e.g., for receiving magnetic resonance or magnetic induction communications), or other components that can be used to receive wireless communications. The receiver components 205 may also include ports for receiving wires communications (e.g., Ethernet ports, fiber optic ports, modem ports).
The disposable wireless receiver 115 of FIG. 2 includes receiver software 215. The receiver software 215 may be used to decode communications and extract messages (e.g., which may include text, images, audio, video, documents, data structures, other software files, other data files, or some combination thereof). Exemplary operations of the receiver software 215 are further illustrated in FIG. 3.
The disposable wireless receiver 115 of FIG. 2 includes a programmable read-only memory (PROM) code 220. The PROM code 220 may be a code programmed into a programmable read-only memory (PROM) of the disposable wireless receiver 115. The receiver software 215 may check the PROM code 220 against a transmission code embedded in the wireless data 110 sent by the wireless transmitter 100 and received by the disposable wireless receiver 115. The PROM code 220 may also be stored at the wireless transmitter 100 as part of a “message code” that is inserted into the wireless data 110 before it is sent by the wireless transmitter 100.
The PROM code 220 can be used by the disposable wireless receiver 115 for one of two security functions. Firstly, the PROM code 220 can be used by the disposable wireless receiver 115 to ensure that the disposable wireless receiver 115 is has permission to read a message included within the wireless data transmission 110. For example, the “message code” stored by the wireless transmitter 100 and sent along with the wireless data transmission 110 may include a list of authorized PROM codes that the disposable wireless receiver 115 may then compare to its PROM code and either decode the message or refrain from doing so. Secondly, the PROM code 220 can be used by the disposable wireless receiver 115 to ensure that the wireless data transmission 110 came from the wireless transmitter 100, since at least part of the “message code” sent along with the wireless data transmission 110 may identify the wireless transmitter 100 and be compared against a list of authorized wireless transmitters that the disposable wireless receiver 115 may receive from.
In alternate embodiments, the disposable wireless receiver 115 may identify whether it is authorized to read a wireless data transmission 110 or whether the wireless data transmission 110 came from the correct wireless transmitter 100 based on a different security method, such as via transfer of symmetric encryptions keys, transfer of asymmetric encryption keys (e.g., as part of a public key infrastructure), or transfer of certificates signed by a certificate authority.
The disposable wireless receiver 115 of FIG. 2 includes a connector controller 240, which allows the disposable wireless receiver 115 to be connected to a user device 120. The disposable wireless receiver 115 may be connected to the user device 120 via a Universal Serial Bus (USB) cable, a lightning cable, a thunderbolt cable, an audio jack cable, a 30-pin cable, an HDMI cable, or another type of cable, which may be controlled and/or monitored by the connector controller 240. Alternately, the disposable wireless receiver 115 may be connected to the user device 120 through a wireless connection, which may be short-range or long-range, such as a Bluetooth connection, a magnetic induction connection, a magnetic resonance connection, a radio frequency identification (RFID) connection, or a near-field-communication (NFC) connection, which may be controlled and/or monitored by the connector controller 240.
The disposable wireless receiver 115 of FIG. 2 includes a power controller 235, which may control power input and output for the disposable wireless receiver 115. The power controller 235 may optionally control and/or monitor power input from a battery 225 of the disposable wireless receiver 115, which may be a replaceable battery (e.g., a set of AA or AAA batteries) or a rechargeable battery (e.g., a lead-acid battery, a lithium-ion battery, a nickel-cadmium battery, a nickel-metal hydride battery, a lithium polymer battery, a lithium-sulfur battery, or a sodium-ion battery). The power controller 235 may also optionally control and/or monitor power input from an external power source 250, which may be power from an alternating current power grid socket, a direct current power socket, a generator (e.g., mechanical, chemical, petrochemical, nuclear, solar, wind, hydroelectric), or an external battery of one of the types described in relation to the battery 225.
FIG. 3 is a flow diagram illustrating exemplary operations of a receiver software. The receiver software 215 may begin at step 405 by receiving wireless data 110 from the receiver hardware 210, which has received the wireless data 110 from the wireless transmitter 100.
At step 410, the receiver software 215 then decodes message content of a wireless data transmission 110. Such message content may include text, images, audio, video, documents, data structures, other software files, other data files, or some combination thereof.
At step 415, the receiver software 215 then extracts a “message code” from the wireless data transmission 110. The message code may include a transmitter code associated with the wireless transmitter 100, a receiver code associated with the disposable wireless receiver 115, or some combination thereof.
At step 420, the receiver software 215 then reads a PROM code 220 from a PROM memory of the disposable wireless receiver 115. The PROM code 220 may include a transmitter code associated with the wireless transmitter 100, a receiver code associated with the disposable wireless receiver 115, or some combination thereof.
At step 430, the receiver software 215 then compares the “message code” of step 410 and the PROM code 220 of step 415.
Step 430 may include checking to see if a transmitter code (that is associated with the wireless transmitter 100) included within the “message code” is also included within the PROM code 220, which would mean that the wireless transmitter 100 is an authorized wireless transmitter from which the disposable wireless receiver 115 is allowed to receive wireless data 110. This could prevent the disposable wireless receiver 115 from picking up noise from other communications, could prevent a malicious third party from sending dangerous data (e.g., malware or a virus) to the disposable wireless receiver 115.
Step 430 may also (or alternately) include checking to see if a receiver code (that is associated with the disposable wireless receiver 115) is included within the “message code” is also included within the PROM code 220, which would mean that the disposable wireless receiver 115 is an authorized recipient of the wireless data 110 sent from the wireless transmitter 100. This could allow control over which disposable wireless receivers 115 of a group of disposable wireless receiver 115 actually work, which could allow an entity to, of example, sell access to communications by selling access to working disposable wireless receiver 115 (and ensuring other disposable wireless receivers 115 won't read those wireless transmissions 110).
If there is a mismatch between the message code and PROM code in step 430, the receiver software 215 can return to step 405.
If there is a match between the message code and PROM code in step 430 receiver software 215 can move on to step 435, in which the receiver software 215 aids in connecting the disposable wireless receiver 115 to the user device 120 (e.g., via the connector controller 240 and any connector or cable or wireless connection described in connection with the connector controller 240 in regard to FIG. 2).
In step 440, the receiver software 215 then checks a set of v settings 140, which may be based on the wireless settings GUI 405, and which may identify different types of allowed or disallowed content sources (e.g., sports content, advertisement content) or content types (e.g., text, images, audio, video, documents, data structures, other software files, other data files). If there is a mismatch between the message content type of the decoded message from the wireless data 110 and the allowed content types or allowed content sources in the wireless settings 140 from the wireless settings GUI 405, the receiver software 215 can return to step 405.
If there is a match between the message content type of the decoded message from the wireless data 110 and the allowed content types and allowed content sources in the wireless settings 140 from the wireless settings GUI 405, the receiver software 215 can then, at step 445, send the message content that was decoded at step 410 from the wireless data 110 to the user device 120, or send the entire wireless data 110 to the user device 120, or both. The user decide 120 may then in some cases then run the message content through a wireless software 130 to be displayed at a wireless application 125 as illustrated in FIG. 4B. The receiver software 215 can return to step 405.
FIG. 4A illustrates an exemplary wireless setting graphical user interface of a user device. The wireless setting GUI 405 of the user device 120 may include a variety of GUI elements, such as checkboxes, buttons, sliders, switches, or radio buttons, and can be used to allow a user to adjust a set of wireless settings 140 stored at the user device 120.
In particular, the wireless settings GUI 405 of FIG. 4A allows editing of wireless settings 140 related to communication sources 410 and of wireless settings 140 related to communication types 415. For example, wireless settings 140 related to communication sources 410 may include allowing data from the disposable wireless receiver 115, allowing advertisement data, allowing emergency data, allowing sports data (e.g., Entertainment and Sports Programming Network or “ESPN”), or the ability to add an input source. Wireless settings 140 related to communication types 415 may include allowing all data, allowing video data, allowing audio data, allowing text data, allowing vibrational data (e.g., vibrations to notify a user of the user device 120 that a certain event has occurred, such as a score or a touchdown), or the addition of an input type.
FIG. 4B is a flow diagram illustrating exemplary operations of a wireless software and an exemplary user interface of a wireless application.
The wireless software 130 operations begin, at step 420, with connecting the disposable wireless receiver 115 to the user device 120 in a wired or wireless manner as described above in relation to FIG. 1 or step 435 of FIG. 3.
The wireless software 130 then, at step 425, checks to see whether receipt of wireless data 110 is indicated. If not, the wireless software 130 can return to step 420. If receipt of wireless data 110 is indicated, the wireless software 130 can move on the step 430.
The wireless software 130 then, at step 430, checks to see whether the receipt of the wireless data 110 is allowed based on the wireless settings 140 associated with the user device 120. If not, the wireless software 130 can return to step 420. If the wireless data 110 is allowed based on the wireless settings 140 associated with the user device 120, the wireless software 130 can move on the step 435.
The wireless software 130 then, at step 425, sends the wireless data 110 to the wireless application 125.
An exemplary GUI for the wireless application 125 is then illustrated in FIG. 4B as well.
The exemplary wireless application 125 includes a visual viewer 440, which can display images and/or video and/or text from the message content of the wireless data 110. The images and/or video and/or text displayed at the visual viewer 440 can be streamed live to the user device 120 or can be pre-recorded and pre-loaded onto the user device 120.
The wireless application 125 can also include playback controls 445, which may allow some control over the playback of videos and/or audio through the visual viewer 440 and/or through an audio output (e.g., speakers or a headphone/auxiliary jack/port/cable), or the playback of images and/or text (e.g., if displayed in a “slideshow” style). The playback controls 445 can include, for example, a play control, a pause control, a rewind control, a fast-forward control, a skip previous control, a skip next control, or some combination thereof. Certain controls might not always be available—for example, a live-streamed video might not have an available a fast-forward control (e.g., unless it had previously been rewound and was currently playing recorded video data) or a skip forward control.
The wireless application 125 can also include an audio volume control, which can adjust the output volume of an audio output (e.g., speakers or a headphone/auxiliary jack/port/cable) of video data from the wireless data 110 and/or of audio data from the wireless data 110.
The wireless application 125 also includes a text setting 455 to turn text on or off. This may adjust the wireless settings 140, or may alternately turn off a particular situation in which text data from the wireless data 110 may be used, such as in the context of closed captions for audio data and/or video data from the wireless data 110.
FIG. 5 illustrates an exemplary overall method of the present invention as described herein.
At step 510, the method includes providing a wireless transmitter 100 capable of transmitting wireless data 110.
At step 520, the method includes providing a disposable wireless receiver 115 capable of receiving wireless data 110, and capable of decoding a message code from the wireless data, and matching the message code to the PROM code 220 of the user device 120, allowing wireless data 110 to be transferred to a connected user device 120 based on whether the codes matched.
At step 530, the method includes providing a user device, capable of receiving a disposable wireless receiver, providing an operating system with wireless software, and a wireless settings data profile, and wireless application.
At step 540, the method includes allowing a user to set wireless settings 140 (e.g., using a wireless settings GUI 405).
At step 550, the method includes allowing the user to input wireless data 100 from the disposable wireless receiver 115, and based upon wireless settings 140, using wireless software 130, transferring wireless data 110 to the wireless application 125.
At step 560, the method includes allowing the user to view wireless data 110 messages through the wireless application 125.
