In some embodiments, a field outline of a treatment beam can be superimposed on the blended beam's-eye view, thereby illustrating whether the planned beam-delivered treatment extends beyond the surface of the skin of the patient. The blended beam's-eye view can facilitate a manual confirmation process that verifies the planned beam-delivered treatment extends beyond the surface of the skin.

Abstract: A selectorized dumbbell has a plurality of nested weights that provide a stack of left weight plates and a stack of right weight plates. A handle is dropped between the stacks and a selector is inserted into one of a plurality of vertically spaced positions on the handle to couple a selected number of the weights to the handle. The selector has a continuous periphery enclosing an open interior. A user who is exercising with the dumbbell will be alerted to unintended dislodgement of the selector since a portion of the selector's periphery will contact a portion of the user's grip hand, wrist or forearm during such dislodgement. This prevents complete dislodgement and prompts the user to restore the selector to a fully installed position. Side walls of the selector may become curved when the selector is installed to provide an additional frictional force resisting dislodgement of the selector.

Abstract: Determining pace or speed based on sensor data may include determining an amount of contact time a user's foot has with a workout surface such as the ground. Contact time may be determined by identifying samples in the sensor data that correspond to various events such as a heelstrike, a toe-off and a subsequent heelstrike. In one example, these events may be identified by determining a sequence of three sample values (e.g., a triplet) that exceeds corresponding thresholds. The validity of an identified triplet (e.g., heelstrike, toe-off and heelstrike) may be confirmed by determining whether a difference between a last event sample and a middle event sample is greater than a difference between the middle event sample and an initial event sample. Once confirmed, a contact time may be determined from the triplet. A linear or non-linear relationship may then be applied to the contact time to determine a speed or pace.

The system receives data associated with a workout of a user from at least one sensor associated with the user, the workout being classified as a first type of workout. The system processes the data to identify at least one time interval during the workout that does not correspond to the first workout type.

If the user chooses to do so, the system removes or reclassifies the subset of the data that is associated with the identified time interval. The system generates and provides workout depictions using the data, at least one of which illustrates only the remaining data that was not removed or reclassified.
