Abstract: Disclosed is a system for identifying a deceleration in a brain activity of a user and reminding the user to take a break to recover from the deceleration of the brain activity. The system includes a smart desk including a sensor unit and a brain activity identification unit. The brain activity identification unit receives (i) user data (such as sleep data, wake up time, and age) from a user device on a particular day, and (ii) sensor data (for example, log-in time, and how long the user is performing the event) for the particular day from the sensor unit. The brain activity identification unit identifies the deceleration in the brain activity of the user based on the user data and the sensor data. The brain activity identification unit is further configured to remind the user to take the break to recover from the deceleration of the brain activity.

Abstract: A connector assembly includes two electric connectors that are configured to be plugged together in a plug-in direction and rotated relative to one another in a direction of rotation into a coupled state, wherein one of the two electric connectors includes a contact and the other one of the two electric connectors includes a mating contact. A mechanical guiding system guides the movement of the two electric connectors relative one another in the plug-in direction and the movement of the two electric connectors relative to one another in the direction of rotation. The mechanical guiding system mechanically couples the movement in the direction of rotation with a movement against the plug-in direction. In the coupled state, the contact and the mating contact are pressed against each other against the plug-in direction.

Abstract: A Bharatnatyam headgear comprising a wearable hair net, the hair net being pliable and expandable to be worn over a dancer's head and covering the head, the wearable hair net matching a color of the dancer's hair. A circular piece is affixed to the hair net. The circular piece is capable of being positioned in a middle of a forehead at a forward end of the hair partition of the dancer. A forehead piece is affixed to the hair net, the forehead piece extending in a horizontal direction capable of being positioned to coincide with a hairline in a left and right direction and extending at least beyond eyebrows of the dancer. A vertical piece is affixed to the hair net, the vertical piece being attached to the circular piece and extending across a middle of the head to cover the hair partition.

Abstract: Any node of a Patricia tree is deleted by selecting as the replacing node the node immediately prior to the deletion node in the unique path to the deletion node. Once the replacing node is determined in this manner, the deletion node is easily removed by simple pointer adjustments of the affected surrounding nodes. Nodes are deleted in time consistent with node insertion time. It is now practicable to use Patricia trees in dynamic situations in which nodes are created and deleted frequently.
