Abstract: A tubular collar adapted to be worn around the neck of an individual. The tubular collar has a front sheet and a rear sheet, each with tapered ends. A fastener is provided on opposite ends of the front and rear sheets. The tubular collar is configurable in an open configuration and a closed configuration. In the closed configuration, the fasteners are attached to each other to affix the tapered ends together to form a loop sized to be placed around the neck of an individual. The tubular collar comprises an opening on the front sheet sized to receive ice or other cooling medium, or a heating medium, within an enclosed space of the tubular collar. By positioning the tubular collar around the neck, the weight of the cooling or heating medium is distributed across the neck and shoulders thereby providing comfort during motion such as during strenuous activities.

Abstract: A smart locker system with assistance for a visually impaired user is disclosed. Each locker in the smart locker system includes a beacon that emits a signal either before the locker door is released or at the same time as the locker door is released. The beacon is used by a visually impaired user to locate the specified locker before it opens or at the same time as it opens. The beacon may be a haptic device that causes the specified locker to vibrate, which allows the user to find the locker by feel. The beacon may also be an auditory device that causes the specified locker to emit a sound, which allows the user to find the locker by sound.
