Abstract: A shoe sole cleaning device may include a fluid reservoir having an inner chamber, a trough fluidly coupled to the fluid reservoir, a brush having bristles and operably connected to an axial shaft, the brush disposed partially within or above the trough, and a motor operably connected to the axial shaft and configured to cause the brush to rotate about the axial shaft.

Abstract: A shoe sole cleaning device may include a fluid reservoir capsule having an inner chamber for containing a cleaning solution. The shoe cleaning device may also include a trough and a fluid pump operably connected to a fluid exit port of the fluid reservoir capsule to pump the cleaning solution from the fluid exit port to the trough. A brush may be disposed partially within the trough such that some of its bristles are at least partially submersible in the cleaning solution in the trough. A motor may cause the brush to rotate about an axial shaft picking up the cleaning solution from the trough to clean a shoe's sole. A fluid recycle conduit may transport the cleaning solution from the trough back to the inner chamber of the fluid reservoir capsule when the cleaning solution in the trough reaches a predetermined height.

Abstract: A dynamometer may include a grip portion extending along a longitudinal axis for gripping by at least a portion of a human hand or foot, and a sensor or plurality of sensors distributed along or below a surface of the grip portion. The sensor or plurality of sensors are configured to detect force exerted by the portion of the human hand or foot in directions radial and tangential to the grip portion such that grip strength and wrist strength of the human may be sensed by the sensor or plurality of sensors.

Abstract: A dynamometer may include a sensor embedded within and distributed uniformly within a pad. The pad may be configured for gripping by a human hand or foot such that grip force of particular elements of the human hand or foot may be sensed by the sensor.

Abstract: A method for cardiopulmonary resuscitation training includes sensing a chest compression force via a distributed sensor, measuring a depth of the chest compression via an accelerometer, calculating depth of the chest compression based at least in part on the sensed chest compression force and, in some cases, on the measured depth of the chest compression.

Abstract: A cardiopulmonary resuscitation training apparatus includes a distributed sensor uniformly distributed on a pad and configured to sense chest compression force throughout the surface area; a controller operatively coupled to the distributed sensor and configured to receive the sensed chest compression force throughout the surface area from the distributed sensor, calculate a chest compression parameter including location or angle of the sensed chest compression force based at least in part on the sensed chest compression force throughout the surface area, compare the calculated chest compression parameter with a predefined value for the chest compression parameter, and produce a performance information which is based on the comparison; and a prompting device operatively coupled to the controller and configured to provide the performance information.
