A solar power conversion kit allows converting of a standard umbrella into a solar charging umbrella, which can then use solar power to charge electronic devices. The solar charging umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.

An embodiment includes a walking stick. The walking stick includes a rod assembly, a water purification assembly, and a manual pump. The rod assembly extends from a first end to a second end that is opposite the first end along a longitudinal direction of the rod assembly. The rod assembly includes at least one rod portion. The water purification assembly is integrated with the rod assembly. The manual pump is configured to impose a pressure gradient in the water purification assembly. The manual pump includes a plunger that is physically coupled to a handle portion. Motion of the plunger relative to the water purification assembly draws water into an inlet tube that is positioned in the rod portion and through the water purification assembly. The motion of the plunger results from translation of the handle portion in substantially the longitudinal direction of the rod assembly.

Provided herein are patient mobility assessment devices having a mobility assistance device with an incorporated distance tracker for use in assessing the ambulation of a recovering medical patient. The distance tracker can be integrated into or removably attached to the mobility assistance device. The information obtained may be displayed on the mobility assistance device and/or at a nurse's station or other remote location for convenient monitoring of patient ambulation. Also provided herein are methods for evaluating patient ambulation using the mobility assessment device and optionally, provision of therapeutic ambulation protocols to a display on the device to assist with patient physical therapy and recovery.

Methods, systems, and products estimate distances to aid a visually impaired user of a mobile device. As the user carries the mobile device, a camera in the mobile device captures images of a walking cane. The images of the walking cane are analyzed to infer a distance between a tip of the walking cane and the mobile device. The distance may then be used by navigational tools to aid the visually impaired user.
