Systems, methods, and non-transitory computer readable media including instructions for performing duty cycle control operations for a wearable extended reality appliance are disclosed. Performing the duty cycle control operations includes receiving data representing virtual content in an extended reality environment associated with a wearable extended reality appliance; identifying in the extended reality environment a first display region and a second display region separated from the first display region; determining a first duty cycle configuration for the first display region; determining a second duty cycle configuration for the second display region, wherein the second duty cycle configuration differs from the first duty cycle configuration; and causing the wearable extended reality appliance to display the virtual content in accordance with the determined first duty cycle configuration for the first display region and the determined second duty cycle configuration for the second display region.

Systems, methods, and non-transitory computer readable media including instructions for selectively operating a wearable extended reality appliance are disclosed. Selectively operating the wearable extended reality appliance includes establishing a link between a wearable extended reality appliance and a keyboard device; receiving sensor data from at least one sensor associated with the wearable extended reality appliance, the sensor data being reflective of a relative orientation of the wearable extended reality appliance with respect to the keyboard device; based on the relative orientation, selecting from a plurality of operation modes a specific operation mode for the wearable extended reality appliance; identifying a user command based on at least one signal detected by the wearable extended reality appliance; and executing an action responding to the identified user command in a manner consistent with the selected operation mode.

A beverage vessel includes: a beverage container in which a beverage may be stored said beverage container having an upper opening by which beverage may be poured in and poured out of the beverage container and a wall extending from the opening to the bottom of the beverage container; a closure element adapted to be positioned in the upper opening of the beverage container; a light distribution element arranged at the closure element; and a light emitter positioned such that the light emitted by the light emitter passes at least a part of the volume of the beverage container before entering the light distribution element; wherein said closure element comprises a locking mechanism, said locking mechanism comprising at least three locking arms extending in radial direction of the beverage vessel to the beverage container, wherein each arm of the locking element comprises an elastic portion being elastic in the radial direction of the beverage vessel; the beverage container comprises at least one concave portion in the wall, said concave portion extending in radial direction of the beverage vessel; and said arms releasably engage in the concave portion in the wall for releasably locking the closure element to the beverage container.

The present invention relates to electric lock.

The electric lock has a housing with a lockable clamp for securing the housing to a cycle that is adapted to receive part of a cycle frame. A tethering connector extends from the housing having first and second ends; the second end of the tethering connector is fixed to the housing and the first end of the tethering connector is secured to the housing by a lock.

An alert means is provided in/on the housing. The tethering connector and the housing define an electrical circuit which is operative to trigger the alert means when the circuit is broken.

A hearing device comprises a processor operatively coupled to memory, a speaker or a receiver, and one or both of a microphone arrangement and a telecoil arrangement. A sensor is operatively coupled to the processor and configured to sense an angular position of the device relative to a horizontal plane oriented orthogonal to a direction of gravity. The processor is configured to detect a change in the angular position of the device from a first angular position to a second angular position, the first angular position corresponding to a specified angular position that provides for a target or optimal level of device performance and the second angular position resulting in suboptimal device performance. The processor is also configured to implement a corrective action that improves performance of the device relative to the suboptimal device performance while operating the device at the second angular position.

An adjustable T-square device and method of use is shown and described herein. The adjustable T-square has a plurality of apertures with at least one locking detent to set precise angles. The adjustable T-square has a locking pin to further engage a ruler portion to a head portion to minimize error when using the device.

A distracted driver detection device for use in a vehicle includes a processor, a video camera, and an accelerometer. The processor is configured to compute an eye open ratio (EOR) and a mouth open ratio (MOR). The processor is configured to provide an audio alert signal to an audio alert component and provide a visual alert signal to a visual alert component when the EOR is less than an EOR threshold for a prescribed EOR assessment time, when the MOR is greater than the MOR threshold for a prescribed MOR assessment time, or when the estimate of the acceleration is greater than an acceleration threshold. The EOR and MOR are calculated from facial landmarks that are generated by a Histogram of Oriented Gradients (HOG) algorithm implemented by the processor.
