Abstract: In one example, we describe a method and apparatus for cleaning the ear canal of cerumen contaminants, dust, and particulates. That includes a handle and replaceable tips, a combination of a flared design and solid base plate attached to the bottom of the tips, limiting the excessive insertion of the tip into the deep area of ear canal that could contact eardrum, which can seriously damage the eardrum and hearing capabilities. The handle has a slot in the front in which a tip can snap into, and as the whole system is secured together, the user can operate the system by spinning the handle, using fingers, e.g., in a clockwise direction, as the user proceeds to insert the tip in the ear canal. Different variations are also presented here.

Abstract: In one example, we describe a device for Crutches and Sitting Device as an improvement of the basic crutch to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries, and who frequently require using crutches for mobility. Normally, the conventional crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. We have solved all these problems here. Many other different variations are shown here, as well, such as walkers and specially curved handles for better grip and less/no injury. Also, we show crutch support in sitting position that works as a simple and handy decompression system for herniated or bulged discs and injured/weak back muscles.

Abstract: In one example, we describe a device for an efficient and compact rack system for knives and other kitchenware. This stylish design integrates: One or more (e.g., three) grinders, a cutting/chopping board, a tray, and a complete full size knife rack, as an example. All these kitchen tools are specifically designed to fit in the same space that a full-size knife rack normally takes. Many different variations are shown here, as well.
