A Baseball Bat Choke-Up Device is provided which includes C-shaped ring with a hollow center cavity that runs longitudinally through the device. An actuator assembly is advantageously provided for permitting actuation of the valve member by a user without requiring the user’s hand or finger to be positioned immediately adjacent to the valve member and the top end of the container. The valve body 21 connects the supply circuit 8 to the downstream circuit 18 for supplying the fluid to the downstream circuit 18 by separating from the valve seat 20. Sense Through The Wall performance parameters including target range, stand-off distance, and probability of detection are improved herein by combining a dynamically positioned sliding windowing function with orthogonal feature vectors that include but are not limited to time amplitude decay, spectral composition, and propagation time position in the return signal data. In some embodiments, the robot scheduler may respond to spontaneous user actions and adaptively schedule or re-schedule robot actions. The input module generates second indicating data based on the first indicating data, the second indicating data being at least partially indicative of the response data.
