Referring to the IoT  IoT device 700 of Figure 7, signal processing and system control 706 controls and coordinates the operation of other components as well as providing signal processing for the IoT device 700. For example signal processing and system control 706 may extract baseband signals from radio frequency signals received from the wireless communication 708 logic, and processes baseband signals up to radio frequency signals for communications transmitted to the wireless communication 708 logic. Signal processing and system control 706 may comprise a central processing unit, digital signal processor, and/or one or more controllers or combinations of these components. 

The wireless communication 708 may further comprise memory 716 which may be utilized by the signal processing and system control 706 to read and write instructions (commands) and data (operands for the instructions). 

A human user or operator of the IoT device 700 may utilize the user interface 722 to receive information from and input information to the IoT device 700. Images, video and other display information, for example, user interface optical patterns, may be output to the user interface 722, which may for example operate as a liquid crystal display or may utilize other optical output technology. The user interface 722 may also operate as a user input device, being touch sensitive where contact or close contact by a use’s finger or other device handled by the user may be detected by transducers. An area of contact or proximity to the user interface 722 may also be detected by transducers and this information may be supplied to the signal processing and system control 706 to affect the internal operation of the IoT device 700 and to influence control and operation of its various components. 

A camera 724 may interface to image processing 726 logic to record images and video from the environment. The image processing 726 may operate to provide image/video enhancement, compression, and other transformations, and from there to the signal processing and system control 706 for further processing and storage to memory 716. Images and video stored in the memory 716 may also be read by the signal processing and system control 706 and output to the user interface 722 for display to a user of the IoT device 700.

Audio signals may be provided to user interface 722 from which signals output to one and more speakers to create pressure waves in the external environment representing the audio. The IoT device 700 may convert audio phenomenon from the environment into internal electro or optical signals by operating a microphone and audio circuit (not illustrated). 

The IoT device 700 may operate on power received from a battery 720. The battery 720 capability and energy supply may be managed by a power manager 718

The IoT device 700 may transmit wireless signals of various types and range (e.g., cellular, WiFi, BlueTooth, and near field communication i.e. NFC). The IoT device 700 may also receive these types of wireless signals. Cellular wireless signals are  transmitted and received using wireless communication 708 logic coupled to one or more antenna 702. Shorter-range wireless signals may be transmitted and received via antenna 704 and wireless communication logic 728. Other forms of electromagnetic radiation may be used to interact with proximate devices, such as infrared (not illustrated).

The device may utilize a haptic driver 732 which controls a vibration generator 714 to cause vibrations in response to events identified by signal processing and system control 706, such as the received text messages, emails, incoming calls or other events that require the user or the device’s attention.

A subscriber identity module ( SIM 710 ) may be present in some mobile devices, especially those operated on the Global System for Mobile Communication (GSM) network. The SIM 710 stores, in machine-readable memory, personal information of a mobile service subscriber, such as the subscriber’s cell phone number, address book, text messages, and other personal data. A user of the IoT device 700 can move the SIM 710 to a different and maintain access to their personal information. A SIM 710 typically has a unique number which identifies the subscriber to the wireless network service provider.

The IoT device 700 may include an audio driver 730 including an audio encoder/decoder for encoding and decoding digital audio files or audio files stored by memory 716, SIM 710, or received in real time via  one of the antenna 702, antenna 704. The audio driver 730 is controlled by the signal processing and system control 706 and decoded audio is provided to one and more speaker 712 to create pressure waves in the external environment representing the audio.
