## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of International Application PCT/182010/000783.


TECHNICAL FIELD OF THE INVENTION
The present invention relates to the technological field of electronics in conjunction with network computer systems. Particularly, this invention comprises an improved bill folder with one or more visual devices and a system that allows dynamic information contents updating to a user.
BACKGROUND OF THE INVENTION
Bill folder devices are commonly known, also identified as a billfold or payment folder, wherein a service provider presents the bill or payment stub with the full account of the service to a customer. For example, some of these services may include restaurants, bars, hotels, and many others. There are some bill folder devices in the State of the Art that include some improvements whose primary purpose is to facilitate the processing and collection of the bill settlement.
An improved bill folder is described in US patent application US2005/0046172 that includes inside a plurality of compartments configured to accommodate a plurality of cards, debit or credit, together with a built-in calculator in the same folder to facilitate customer calculation of the bill. Similarly, U.S. Pat. No. 6,076,079 protects a calculator with a display adapted for tip calculation; wherein said calculator is coupled to a bill folder or payment folder. Further to the electronics usually used in a calculator, the bill folders described in both documents do not exhibit further improvements in the electronics field or integration to information systems.
Moreover, U.S. Pat. No. 6,050,214 protects a bill folder device that presents a tab type visual indicator which slides on two or more colored areas that allow the service provider to know the payment status of the customer. However, this simple invention does not involve electronic components, which in conjunction with information systems facilitate the payment procedures. Similarly, U.S. Pat. No. 5,355,115 shows a bill folder with colored flags type signals, wherein each color indicates to the service provider a payment status of the service bill. In this patent, a lightning control circuit for the flag signal that improves viewing, as well as electronic elements are incorporated. However, this bill folder excludes information systems integration. Also, U.S. Pat. No. 6,796,673 protects a bill folder wherein a lighting signal is turned on by the user to indicate that the service provider may collect the bill folder. Once again, although this invention includes electronic components for lighting and signaling, this does not include information systems integration.
There are other numerous bill folder devices directed to solve the problem of bill or payment stub viewing per se at the time the service provider is presenting it to the customer. For example, U.S. Pat. Nos. 6,409,357, 6,808,208, 7,163,307, 7,270,437, and 7,277,241, describe payment folders with illumination means on the area holding the pay stub or bill. U.S. Pat. Nos. 6,808,208 and 7,270,437 also combine the use of lens or magnifying glass to facilitate reading the customer's bill. Moreover, U.S. Pat. Nos. 6,409,357 and 7,163,307, and U.S. patent application no. US2002/0093813 use sensors that detect the opening of the bill folder and automatically turn on the illumination means.
Additionally, the State of the Art include other bill folder devices which include illumination applied for advertising purposes, such as those described in U.S. patent application 2007/0115650, and in U.S. Pat. No. 5,813,748. Both inventions describe and illustrate in the exterior and interior of the device one or more panels, illuminated from inside or backlit. The function of these panels is to function as an advertising display or showcase to display any advertising sign, logo, or image. In both documents, the panels are limited to show a single image statically. None of these documents suggests an integration of information systems to improve the content presented to the customer in the panels.
Also, U.S. patent application no. US2007/0215695 describes a device and system to present and facilitate the settlement of a restaurant bill. This device is embedded into a bill folder, and has an input and display touch screen, a magnetic card reader to enter payment information, and a system with a memory means to execute computer instructions, a processing unit of computer instructions, additional optional memory means, input devices, output devices, and communication links, which can be wired or wireless. The disadvantage of this bill folder is that it is directed exclusively to present payment information and not any other information that may be useful to the customer. Additionally, another disadvantage is that both the tactile and the magnetic card reader are directed to solving the payment problem through data entry which processing is complicated, requires high security connections and authentication processes with financial institutions whose data processing is more complex. Moreover, this device lacks of means for indicating when the device is in use, which will optimize the use of the battery. Moreover, this device also lacks of means for adjusting the information display device automatically under light conditions at the site. Still further, this device has the disadvantage of lacking a mechanism to detect if the device leaves the location area without authorization, such as in case of theft. Finally, this patent document also discloses the charging means for this device.
Finally, U.S. patent application no. US2002/0194072 describes a device exclusively oriented to perform customer satisfaction surveys. The document describes a device with calculator and data input means allowing the user to introduce the survey responses. Moreover, the document states that these devices can be charged into a base, wherein at the same time extracts the survey data. The disadvantage of this document is that the device does not permit nor considers displaying information of other nature that can be useful to the customer. Moreover, this device lacks of means for indicating when the device is in use, which will optimize the use of the battery. Still further, this device also lacks of means for adjusting the information display device automatically under light conditions at the site. Finally, this device has the disadvantage of lacking a mechanism to detect if the device leaves the location area without authorization, such as in case of theft.
Therefore, there is a need in the prior art for a bill folder or check bill presenter to facilitate the interaction of dynamic information content relevant to a customer during a service payment process. Likewise, the present invention solves the technical problem of integrating a dynamic information content system to a bill folder by electronic components that allow to interact, to optimize energy use and to maintain safe the bill folder.
OBJECT OF THE INVENTION
The main aspect of the present invention is to provide a bill folder that facilitates relevant information to the customer during a service payment process.
Another aspect of the present invention is to solve the technical problem of integrating a remote or in situ content updating system in said bill folder.
Moreover, another aspect is to display this information in a dynamic manner and tailored to each location, regime, level, and type of service.
Finally, another aspects are the customer interaction, energy use optimization, and keeping safe the bill folder.

Such real time clock (205) is controlled by an inter-integrated circuit or IIC, and preferably has an independent power source such that in case of power cut, the clock operation keeps working. In accordance with the second and fourth embodiments described above, the clock stands for cases in which the bill folder (10) does not have access to a communication system that allows to update time automatically, to reproduce scheduled associated images, and to generate usage log. Additionally, real time clock can be external.
Optionally, an accelerometer module comprising an SPI/IIC interface connected to an accelerometer (231). The accelerometer (231) can be employed for detecting vibration and movement of the bill folder (10), or as means of interaction with the user while detecting certain positions.
Optionally, a vibration module comprising a vibration sensor (232) that may replace the accelerometer, but its application is limited to determine if the bill folder (10) is in use and not in idle. This vibration sensor may replace the accelerometer, or may work together to minimize power consumption.
Optionally, a light sensor module comprising an SPI/IIC interface connected to a light sensor (233). The purpose of this light sensor (233) is to measure the ambient light for contrast adjustment of visual devices (55, 65).
Optionally, a opening sensor module comprising the sensor (83) that transmits information to the processor (75) of when the bill folder (10) is opened for turning on the visual device (65) or closed for turning off the visual device (55). Preferably, the sensor is magnetic of hall effect type. However, the sensor (83) can be selected from other type of known opening sensors such as: reed type sensors, magnetic-resistances, optical sensors, proximity sensors, and pressure sensors, among others known.
A visual device module allows the processor to send information to a visual device (55, 65), through the PCB (57, 67). In the preferred embodiment, the visual device module will automatically select the display of information in either the first visual device (55) when the bill folder (10) is in closed position, or the second visual device (65) when the bill folder (10) is in open position. In another embodiment, such visual device module may display information in both visual devices (55, 65) at the same time. In the preferred embodiment, the visual device (55, 65) are color TFT LCD displays with back lighting means. In an alternative embodiment, the visual devices (55, 65) have an integrated graphics controller. In another alternative embodiment, the visual devices (55, 65) do not have an integrated graphics controller which can be integrated into the PCB (57, 67). Notwithstanding the above options, the visual devices (55, 65) may also comprise other display technologies such as the organic light emitting diode or OLED technology, with or without means to implement a “touch-screen” type interaction or e-ink like technologies.
Optionally, a radio module comprising a radio transceiver (242) for providing protection to the bill folder (10) against theft. The radio module allows establishing a link with a beacon placed on the entrance of the service location to determine if any bill folder (10) has left the facility. Preferably, the radio transceiver (242) is 900 MHz for ISM band that will notify the service provider if the product is located outside a predetermined area. The radio transceiver can be calibrated in accordance with each location predetermined area.

The wireless communication module enables wireless connectivity of the bill folder (10) to the remote content updating system (100) for making modifications to the image files, playlist, as well as the statistics collection available in the log of the third embodiment. In the preferred embodiment is suggested to use WiFi interface. However, the wireless connection may include bluetooth, infrared, radio frequency, satellite link, and GPRS, among other known wireless connections.
The function of the bill folder (10) of the present invention is described below. During its operation, the bill folder (10) remains at idle until the vibration sensor (232) and/or the accelerometer (231) indicates to the processor (75) that the bill folder (10) is in motion, and therefore in service. When entering service, the bill folder (10) starts the play application of dynamic information in the first visual device (55) located at the lid (21) into the first enclosure (50) protected by the front lid (51). Until the opening sensor (83) sends a signal to the processor that the bill folder (10) has been opened, the processor disables the first visual device (55) and activates the second visual device (65) located on the cover (22) into the first enclosure (50) protected by the back lid (61). If the bill folder (10) is closed again, the opening sensor (83) sends a signal to the processor that the bill folder (10) has been closed so that the processor (75) disables the second visual device (65), and activates again the first visual device (55). If the opening sensor (83) detects an opening again, the processor disables once again the first visual device (55), and activate the second visual device (65). This cycle can be repeated as many times as necessary. Preferably, it is possible to define an activation time where if no motion or use of the bill folder (10) is detected, then it enters in idle mode.
In the first and third embodiments described above, the dynamic information, as well as its programming, are housed in the content server (110) which communicates via internet (120) and an access point (130) with the wireless transmission interface (241) controlled by the processor (75). The server (110) provides dynamic information to any memory available on the bill folder (10), either internal or removable.
Internally, the processor (70) is configured to perform the following steps illustrated in FIG. 16: exiting from an idle state to an active state (301), connecting to the content server (302), receiving dynamic information from server (303), deleting previous dynamic information of the corresponding memory (304), overwriting the received dynamic information in the corresponding memory (305), and entering in idle state (306).
In the second and fourth embodiments described above, the dynamic information, as well as its programming, are housed in the content server (110) which is recorded into a removable external storage medium (222, 224). The removable external storage medium (222, 224) is connected to the corresponding port so that the dynamic information reaches the processor (75) through the USB interface (221) or the memory card interface (223), depending on the case.
Internally, the processor (70) is configured to perform the following steps illustrated in FIG. 17; exiting from an idle state to an active state (311), connecting to the corresponding interface (312), and entering in idle state (313).
Based on the above disclosure, certain embodiments and details have been described to illustrate the present invention and will be apparent to those skilled in the art that variations and modifications can be made without departing from the scope of the present invention.
