Abstract: A modular sensing device can generate output via one or more output devices. The modular sensing device can include an inertial measurement unit that generates sensor data corresponding to user gestures performed by a user, a wireless communication module, a mode selector enabling the user to select a mode of the modular sensing device out of a plurality of modes, and one or more output devices configured to generate output based on the user gestures and the selected mode. The selected mode configures the manner in which the modular sensing device generates output via the one or more output devices based on the user gestures.

Abstract: An apparatus has a chassis that has a pair of rear wheels that passively rotate and a pair of front wheel sets. Each pair of front wheel sets has an upright with an affixed motor. A front wheel is fixed relative to the upright and engages with the motor. A linkage connects the chassis to each of the uprights and is configured to move the uprights in a first range of motion. A linkage actuator actuates the linkage.

Abstract: A system can include a wearable device and a self-propelled device. The wearable device can include a controller that, in response to a user input on the mode selector, initiates a selected mode from a plurality of modes on the wearable device. The selected mode can cause the controller to establish a communication link with the self-propelled device, and generate an output using a feedback mechanism instructing the user to perform a series of actions with the wearable device. In accordance with the selected mode, the controller can interpret sensor data from one or more sensors to determine whether the user has performed the series of actions while utilizing the wearable device. Based on determining whether the user has performed the series of actions, the controller can generate one of a positive or a negative feedback using the feedback mechanism.

Abstract: In a preferred embodiment, a restraint system is described for restraining a standing occupant in a vehicle such as a plane or helicopter. The restraint system includes a webbing strap that winds and unwinds from a spool assembly. The spool assembly includes a trigger assembly that locks a spool from rotation, a manual release assembly for manually releasing the trigger assembly and lock, and an adjustable payout assembly that determines the maximum length that the webbing strap can be pulled out before stopping (i.e., the number of rotations of the spool). The trigger assembly can trigger the lock assembly from one or more sensors. Further, the trigger assembly can be arranged to automatically unlock after a triggering event, manually unlocked after a triggering event or a combination of the two for different sensors.
