Abstract: A hair cutting appliance is presented including a body with a power switch and a power source. A drive system within the body is in selective electrical communication with the power source. A cutting unit is coupled to the drive system. An optical sensor is positioned to sense a pre-defined skin-hair edge in an area in front of the cutting unit. A switching element is in electrical communication with a control circuit and switchable between a conducting state to electrically connect the drive system and the power source and a non-conducting state to electrically isolate the drive system from the power source. The switching element is switched to the non-conducting state when a first sensed condition of the optical sensor exceeds a first pre-programed threshold. A power transform module is also provided that includes the optical sensor and is configured to be mounted to the body.

Abstract: A smart personal grooming device or otherwise cutting device comprises a body with a handle, a head portion, a hair cutting implement, and a camera oriented toward the hair cutting implement. The camera captures images of a skin area and a hair area of a user and a processor detects, based the images, each of the skin area and the hair area. A boundary is defined between the skin area and the hair area. The processor determines a control state based on the boundary that causes the processor to implement one or more algorithms controlling an operating or feature of the smart personal grooming device or otherwise cutting device, including, for example, activating the cutting implement to cause the cutting implement to remove hair in a hair area of the user.

Abstract: Sensor-based systems and methods of analyzing shaving usage based on time duration and shave event status. A shaving device comprises a blade. The shaving device is communicatively coupled to a sensor and one or more processor(s). Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define shaving stroke(s) based on pressure applied to the user's skin. Based on the one or more shaving strokes and timer intervals thereof, a total duration can be tracked. In addition, a shaving event can be determined based on the shaving stroke(s). An output associated with the shaving device may be generated based on the determining that each of a predetermined duration threshold value and a predetermined shave event threshold value has been met or exceeded, the output comprising an indication that the each of the thresholds has been met or exceeded.

Sensor data is collected from the sensor while a user is shaving, and user-specific pressure data is determined therefrom to define one or more shaving strokes based on pressure applied to the user's skin. Based on the one or more shaving strokes, a shaving event can be detected and a shave event count value can be an incremented. The shave event count can be determined to meet or exceed a predetermined threshold value. An output associated with the shaving device may be generated based on the determining that the shave event count value meets or exceeds the predetermined threshold value, the output comprising an indication that the shave event count value meets or exceeds the predetermined threshold value.

Abstract: A first application uses a user interface (UI) component of a second application to determine a user intent based on user input and then determines an action to perform based on the determined user intent. The first application makes it easier for the user to learn the UI of the second application. Example methods include a first application displaying a first content item, the first content item being content of the first application, and the first application displaying a second content item, the second content item being content of a second application. The method may further include in response to a second selection of a second user interface item associated with the second content item, the first application, determining a user intent and an action associated with the user intent based on a second user interface, the second user interface associated with the second application.

Abstract: Systems and methods are provided for notifying users about videos in a playback sequence. The systems and methods determine that a video that meets a criterion is currently available on a video server associated with a messaging client. In response to determining that the video that meets the criterion is currently available, the messaging client on the client device prefetches a sequence of videos from a recommendation engine that match a profile of a user associated with the messaging client. The recommendation engine is being used to provide sequence of videos to a video playback graphical user interface (GUI) that automatically plays back the videos in the sequence. The systems and methods determine that the video that meets the criterion is in a first position in the sequence of videos and, in response, present a notification that indicates the availability of the video on the video playback GUI.

Abstract: Sensor-based systems and methods of analyzing shaving performance. A shaving device comprises a handle having a connecting structure connected to a hair-cutting implement (e.g., a blade). Sensor data is collected from sensor(s) associated with the shaving device during one or more shaving strokes of a user shaving with the shaving device. Shave stroke data is determined from the sensor data that defines one or more shaving strokes. The shave stroke data and a threshold value is input into a model (e.g., an artificial intelligence model) to output a user-specific shave score. Generation of the user-specific shave score comprises comparing the shave stroke data to the threshold value to determine a deviation from the threshold value. An output is generated based on the user-specific shave score.
