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: 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.

Abstract: Sensor-based shaving systems and methods of analyzing a user's shave event are described for determining a unique threshold value of the user. A grooming device comprises a handle having a connecting structure connected to a hair cutting implement. A shave event sensor associated with the grooming device measures a user behavior, which includes collecting a first dataset comprising shave data defining a shave event. The first dataset is transmitted via a communication device and is analyzed to determine baseline behavior data of the user, and a unique threshold value of the user is determined from the baseline behavior data. One or more subsequent datasets, each comprising shave data of one or more corresponding shave events, is compared to the unique threshold value to determine comparison data. An indication is provided, based on the comparison data, to indicate a deviation from the threshold value and to influence the user behavior.
