Qualcomm Internet of Things R&D Insights from Patents

Patents are a good information resource for obtaining IoT (Internet of Things) R&D status in a company. Followings are some examples of patents that provide Qualcomm IoT R&D status: smart home, connected car, cloud service for IoT, industrial IoT and IoT connectivity (LED visible light communication).

Smart Home
US20150185713 (PREEMPTIVELY TRIGGERING A DEVICE ACTION IN AN INTERNET OF THINGS (IoT) ENVIRONMENT BASED ON A MOTION-BASED PREDICTION OF A USER INITIATING THE DEVICE ACTION; Qualcomm) illustrates a smart home system that IoT devices automatically perform their function based on the monitored user behavior.  The supervising apparatus receives report(s) indicating user-initiated event(s) detected by a set of IoT devices within the IoT environment of the user. The apparatus scans the motion data within a threshold period of time preceding particular detected user-initiated events to identify motion sequence(s) within the IoT environment that occurred during the threshold period of time. Certain motion sequence(s) are correlated with user-initiated event(s) based on a confidence level that the user-initiated event(s) will follow the motion sequence(s). Upon detection of the motion sequence(s) at some later point in time, the correlated event(s) is preemptively triggered without user interaction.

For example, a user may have a habit of falling asleep while watching TV in his/her living room every night, and after waking up the user typically turns off the TV and the lights in his/her house and then going to sleep. In this user behavior, the motion sequence of "user picks up remote and points it towards TV screen" may have a 2% confidence level of preceding a "turn off TV and lights" event overall (e.g., because the user performs this action when he/she turns on the TV or changes channels during the day), but may have a 99% confidence level when detected between midnight and 5 AM in the morning when the TV is in an "ON" state. In this case, the TV status of being "ON" can be reported, and this TV state information can be used along with the current time to improve refine the confidence level of a "user turns off TV and lights" event being preceded by a "user picks up remote and points it towards TV screen" motion sequence.

Connected Car
US20150149042 (SYSTEM AND METHOD FOR CONFIGURING AN INTERIOR OF A VEHICLE BASED ON PREFERENCES PROVIDED WITH MULTIPLE MOBILE COMPUTING DEVICES WITHIN THE VEHICLE; Qualcomm) illustrates a connected car system that provide user-specific preferences based on user profile information provided by the mobile devices. The vehicle controller can implement user-specific preferences stored in association with the detected mobile device. Preferences can include seat adjustments, temperature controls, mirror adjustments, music settings, and other similar adjustable vehicle features. These preferences can be stored on the controller, which loads the preferences based on detecting the mobile device in vicinity of the vehicle. User preferences can be determined and set by the vehicle controller before the door is opened and the user enters the vehicle.

Cloud Service for IoT
US20150156266 (DISCOVERING CLOUD-BASED SERVICES FOR IOT DEVICES IN AN IOT NETWORK ASSOCIATED WITH A USER; Qualcomm) illustrates the offering of cloud-based services for IoT devices in an IoT network. In particular, an IoT gateway or other suitable device can discover information (e.g., device classes) about the IoT devices in the IoT network, discover cloud-based services tagged with the discovered information about the IoT devices, and offer the discovered cloud-based services in the IoT network.

For example, the cloud service providers publish the cloud-based services that they develop to a first cloud service publisher, while other cloud service providers may publish their cloud-based services to another cloud service publisher. Accordingly, the IoT gateway discovers the generic and/or specific device classes associated with the various IoT devices in the IoT network associated with the user, discover hosted cloud-based services available for the discovered generic and/or specific device classes from the cloud service publishers, and the offer the discovered cloud-based services to the user.

Industrial IoT

US20140244017 (DETERMINING ITEMS TO BUILD BASED ON AN INTERNET OF THINGS (IOT) NETWORK INVENTORY AND BUILDING THE DETERMINED ITEMS USING A 3D PRINTER; Qualcomm) illustrates the inventory management using a 3D printer to build the items exploiting IoT network. The supervisor device is used to observe, monitor, control, or manage the communications , systems and thus, determine an inventory that exists within the IoT network. Furthermore, the supervisor device communicates with various other components in the systems to determine what inventory needs may exist, identify an appropriate source to obtain 3D printer blueprints or other suitable information to create or replicate the needed inventory, and obtain appropriate rights (e.g., a license) to create or replicate the needed inventory.

In response to suitably obtaining the 3D printer blueprints and appropriate rights to create or replicate the needed inventory, the supervisor device coordinates scheduling creation or replication of the needed inventory via the 3D printer based on a priority scheme, timing criteria, resource availability, or other suitable factors and appropriately update the inventory that exists within the IoT network in response to the 3D printer successfully creating physical objects that correspond to the needed inventory. Additionally, the supervisor device stores inventory data that corresponds to the inventory that exists within the IoT network, the inventory needs in the IoT network, and/or any other suitable inventory data that are relevant to the current inventory or needed inventory within the IoT network.

IoT Connectivity

Thus, visible light communication (VLC) with LEDs as transmitters and receivers for wireless communication can provide the IoT connectivity in many IoT applications. US20150223277 (USING VISIBLE LIGHT COMMUNICATION TO MANAGE WIRELESS COMMUNICATIONS BETWEEN DEVICES; Qualcomm) illustrates the LED VLC for the smart home/building IoT applications. The LED VLC is a type of wireless communication in which the intensity of a VLC signal may be modulated to carry information. The LED VLC can be useful in that VLC can enable communication over relatively long distances within a room or building, yet also confine communication to a room or building (e.g., because the LED VLC signals do not pass through opaque walls). The LED VLC can also be useful in that VLC signals may be received using, for example, an image sensor of a device camera and/or an ambient light sensor of a device, which sensors may be included on cellular devices (e.g., smartphones), computers (e.g., tablet computers), and/or certain wearable devices (e.g., watches and/or electronic glasses).

Each of the LED VLC transmitting devices are an IoT device such as an illumination device (e.g., a light bulb), an appliance (e.g., a television or a thermostat), and/or a wearable device (e.g., a fitness monitor, a watch, or electronic glasses). Each of the LED VLC transmitting devices can communicate each other and broadcast a LED VLC signal including an identifier of the LED VLC transmitting device. A configurator device receives the LED VLC signal broadcast by a LED VLC transmitting device when the LED VLC signal illuminates, for example, an image sensor and/or an ambient light sensor of the configurator device. The configurator device can manage communications among the IoT devices in a smart way exploiting the broadcasted identifier of the IoT devices.
