Description of the Related Art
In the service industry, the best way to increase customer satisfaction is by directly providing appropriate and immediate services to customers. One accepted method to improve service at a restaurant it to deploy a radio system. Each waiter can have a handheld transceiver, also called a Walkie-Talkie, and the waiter can broadcast their voice to other waiters via the handheld transceiver when messages needed to be transmitted between the waiters. For example, when a hostess notices that a customer needs a specific service, the host can notify other waiters of the specific service via the handheld transceiver, so that a waiter can provide the specific service for the customer.
On the other hand, when a customer is in a restaurant, and the customer needs a specific service, such as ordering food, having their water refilled, or receiving the check, the customer always raises a hand to attract the waiter and communicate their requests. However, during busy times, it is not easy to find a waiter, the customer's requests cannot be handled in real-time, and this results in customer dissatisfaction. Currently, wireless service bells have been deployed in some restaurants. Customers can push a service bell set on the table when they need service. The service bell can wirelessly transmit signals to reception equipment set on a counter or it can be worn by a waiter, so that the customers' calls can be attended to by the waiter without delay.
As described, the wireless service bells need compatible reception equipment. The cost of related equipment will become an additional burden for restaurants. Additionally, the deployment of related equipment may cause damage to the original decoration of restaurants. In view of the considerations of cost and beauty, restaurant owners may be reluctant to implement such a service even if they agree the advantages of related services. Therefore, there exists an opportunity to significantly reduce the drawbacks of prior arts and improve customer satisfaction by integrating related services with a radio system, resulting in a solution that will be more readily adopted by restaurants.

Any sensor that can detect the posture and/or motion of an electronic device can be applied in the present invention. As described, the sensor can detect the posture of the specific electronic device. It is understood that, in some embodiments, the posture can be the angular information of the specific electronic device 140 in regard to at least one reference point. In some embodiments, the posture of the specific electronic device can be represented by an angle corresponding to an axis which is vertical to at least one plane of the specific electronic device in regard to a specific direction, such as the gravity direction or the geographical direction.

When the motion and/or posture of the specific electronic device 140 does not conform to the predefined motion and/or posture (No in step S904), the procedure returns to step S902. When the motion and/or posture of the specific electronic device 140 conforms to the predefined motion and/or posture (Yes in step S904), in step S906, specific data is generated according to the motion and/or posture of the specific electronic device 140.

In step S1102, the specific electronic device 140 determines whether a specific condition is met or not. It is noted that, the specific condition may be different according to different requirements and applications. For example, the specific condition may be a specific time. When the current time reaches the specific time, the specific condition is met. In another example, the specific condition may be a specific region. When the location of the specific electronic device 140 is within the specific region, the specific condition is met. In another example, a sensor of the specific electronic device 140 can detect related data, such as an environmental factor, and it is determined whether the detected data conforms to a specific threshold value or a specific state. When the detected data conforms to the specific threshold value or the specific state, the specific condition is met. For example, the sensor may be a temperature sensor for detecting the temperature of an environment where the specific electronic device 140 is in. In another example, the sensor may be a pressure sensor for detecting the pressure of an environment where the specific electronic device 140 is in. It is noted that, the above sensors are only examples of the present application, and the present invention is not limited thereto. When the specific condition is not met (No in step S1102), the procedure remains at step S1102. When the specific condition is met (Yes in step S1102), in step S1104, specific data is generated.

In some embodiments, the specific electronic device 140 can continuously transmit the generated specific data via a wireless network. After the first electronic device 110 receives the specific data transmitted by the specific electronic device 140, the first electronic device 110 can connect to the specific electronic device 140, and instruct the specific electronic device 140 to stop generating and transmitting the specific data.
FIG. 12 is a flowchart of another embodiment of a sound generation and transmission method using a radio transmitter of the invention.
In step S1202, the specific electronic device 140 generates specific data. It is noted that, the specific data can be generated according to the embodiment of FIG. 9, FIG. 10, or FIG. 11. Then, in step S1204, the specific electronic device 140 wirelessly broadcasts the specific data via the network connecting unit 141 in the peripheral mode. It is noted that, the network connecting unit 141 may be a network connecting unit implemented with a low-power consumption technology, such as Bluetooth Smart technology. In the embodiment, the network connecting unit 141 has data broadcasting capabilities, and the network connecting unit 141 cannot actively connect to other electronic devices, wherein the network connecting unit 141 can be passively connected by other electronic devices. In step S1206, the first electronic device 110 performs a scanning process via the network connecting unit 112 in the central mode, thus to determine whether a signal is received or not. It is noted that, in some embodiments, the network connecting unit 112 may be a network connecting unit implemented with a low-power consumption technology, such as Bluetooth Smart technology. In the embodiments, the network connecting unit 112 has data receiving capabilities, and the network connecting unit 112 can actively connect to other electronic devices. When no signal is received (No in step S1208), the procedure returns to step S1206. When a signal, such as the specific data transmitted by the specific electronic device 140 is received (Yes in step S1208), in step S1210, a specific sound is generated according to the received specific data. It is understood that, since the specific data comprises the identification data corresponding to the specific electronic device 140, the specific sound comprises a sound fragment corresponding to the identification data, such that users who heard the sound fragment can realize the specific sound corresponds to the specific electronic device 140. Then, in step S1212, the specific sound is output via the sound output unit 116. Similarly, in some embodiments, the storage unit of the first electronic device 110 can store a plurality of candidate sounds. The processing unit 118 can select one of the candidate sounds as the specific sound according to the specific data, and output the specific sound via the sound output unit 116. In some embodiments, the processing unit 118 can analyze the specific data to obtain a plurality of texts or numbers, transforms the texts or numbers into the specific sound according to a text to sound algorithm, and output the specific sound via the sound output unit 116. In step S1214, the radio transmitter 120 determines whether any sound is received via the sound input unit 122. It is noted that, in some embodiments, the radio transmitter 120 can be placed nearby the first electronic device 110. When the first electronic device 110 outputs sounds in an environment, the sound input unit of the radio transmitter 120 can obtain the sounds in the environment. In some embodiments, the sound input unit 122 of the radio transmitter 120 can be connected to the sound output unit 116 of the first electronic device 110 via the audio connectivity cable 130, such that the sounds generated by the first electronic device 110 can be received. When no sound is received (No in step S1214), the procedure remains at step S1214. When a sound is received, such as the specific sound output by the first electronic device 110 (Yes in step S1214), in step S1216, the specific sound is broadcasted in the frequency range of VHF or UHF via the radio transmission module 124. It is noted that, the frequency range of the wireless network used by the first electronic device 110 and the specific electronic device 140 is different than the frequency range used by the radio transmitter 120. It is noted that, when the radio transmitter 120 broadcasts the specific sound in the frequency range, other radio reception devices can receive the specific sound in the frequency range.

FIG. 13 is a schematic diagram illustrating another embodiment of a sound generation and transmission system using a radio transmitter of the invention. The sound generation and transmission system using a radio transmitter 1300 can be used in an electronic device, such as a handheld transceiver or Walkie-Talkie. The sound generation and transmission system using a radio transmitter 1300 comprises a network connecting unit 1310, a storage unit 1320, a radio transmission module 1330, and a controller 1340. The network connecting unit 1310 can connect to other electronic devices having wireless connecting capabilities via a network, such as a wired or a wireless network such as Wi-Fi or Bluetooth network. Similarly, in some embodiments, the network connecting unit 1310 may be a network connecting unit implemented with a low-power consumption technology, such as Bluetooth Smart technology. The network connecting unit 1310 has two modes, such as a central mode and a peripheral mode. In the central mode, the network connecting unit can receive data from the network connecting units of other electronic devices, and the network connecting unit can actively connect to other electronic devices. In the peripheral mode, the network connecting unit can broadcast signals, such as its identification data. However, the network connecting unit cannot actively connect to other electronic devices in the peripheral mode. In some embodiments, the network connecting unit 1310 is in the central mode. In other words, the network connecting unit 1310 has data receiving capabilities, and the network connecting unit 1310 can actively connect to other electronic devices. The storage unit 1320 can store related data. The radio transmission module 1330 may be a transmitter with at least one antenna. The transmitter can broadcast data in a specific frequency range, such as VHF or UHF. The controller 1340 can control related operations of hardware and software in the electronic device. It is understood that, in some embodiments, the electronic device can have VOX capabilities. When any sound is detected by the controller 1340, the sound is automatically broadcasted in the specific frequency range via the radio transmission module 1330.
FIG. 14 is a flowchart of another embodiment of a sound generation and transmission method using a radio transmitter of the invention. The sound generation and transmission method using a radio transmitter of the invention can be used in an electronic device having network connecting capabilities.
In step S1402, it is determined whether any data is received via a network connecting unit of the electronic device. It is understood that, in some embodiments, the network connecting unit may be a network connecting unit implemented with a low-power consumption technology, such as Bluetooth Smart technology. The Bluetooth Smart technology supports two modes: central and peripheral. In some embodiments, the network connecting unit is in the central mode. In other words, the network connecting unit has data receiving capabilities, and the network connecting unit can actively connect to other electronic devices. When no data is received (No in step S1402), the procedure remains at step S1402. When data, such as specific data transmitted by a specific electronic device is received (Yes in step S1402), in step S1404, a specific sound is generated according to the received specific data. It is understood that, in some embodiments, a storage unit of the electronic device can store a plurality of candidate sounds. One of the candidate sounds can be selected as the specific sound according to the specific data. In some embodiments, the specific data can be analyzed to obtain a plurality of texts or numbers, and the texts or numbers can be transformed into the specific sound according to a text to sound algorithm. Then, in step S1406, the specific sound is broadcasted in a specific frequency range, such as VHF or UHF via a radio transmission module of the electronic device. It is noted that, when the radio transmission module broadcasts the specific sound in the specific frequency range, other radio reception devices can receive the specific sound in the specific frequency range.
In an example of FIG. 15, a specific electronic device (140a, 140b, 140c) can be set on a table of a restaurant, and one or more waiters can wear a radio reception device (160a, 160b, 160c), wherein the radio reception device operates in a specific frequency range, such as VHF or UHF. When a customer of a specific table needs service, the customer can press a physical key of the specific electronic device or shake the specific electronic device. For example, the customer can easily and elegantly complete a procedure for service request by pressing a physical key of the specific electronic device 140a or shaking the specific electronic device 140a, thus driving the specific electronic device 140a to generate and broadcast specific data via a wireless network, such as a Bluetooth network. First electronic device 110, such as a smart phone or a tablet computer can receive the specific data broadcasted by the specific electronic device 140a via a wireless network. The first electronic device 110 can generate a specific sound, such as ‘the specific table requests services’ according to the specific data, and output the specific sound to a radio transmitter 120 via an audio connectivity cable 130. The radio transmitter 120 can have VOX capabilities. When the specific sound output by the first electronic device 110 is detected, the radio transmitter 120 automatically broadcasts the specific sound in the specific frequency range, such as VHF or UHF. The radio reception devices (160a, 160b, 160c) worn by the waiters can receive the specific sound, so that the waiters will know the specific table requests services and provides services in real-time. It is noted that, the example in a restaurant is only an example of the present application, and the present invention is not limited thereto. The present invention can be used in any place, such as a restaurant, hospital, school, store, sports course, factory, or house.
Therefore, the sound generation and transmission systems and methods using a radio transmitter of the present invention can generate sounds according to received signals, and transmit the sounds via a radio transmitter. The present application provides a definite and novel signal transmission mechanism, in which existing equipment can be efficiently integrated to reduce deployment costs of related equipment, and improve user satisfaction for related services.
Sound generation and transmission methods using a radio transmitter may take the form of a program code (i.e., executable instructions) embodied in tangible media, such as floppy diskettes, CD-ROMS, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine thereby becomes an apparatus for executing the methods. The methods may also be embodied in the form of a program code transmitted over some transmission medium, such as electrical wiring or cabling, through fiber optics, or via any other form of transmission, wherein, when the program code is received and loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for executing the disclosed methods. When implemented on a general-purpose processor, the program code combines with the processor to provide a unique apparatus that operates analogously to application specific logic circuits.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. Those who are skilled in this technology can still make various alterations and modifications without departing from the scope and spirit of this invention.
