Abstract: This invention relates to the art of methods and apparatuses for grinding various materials into smaller particles; particularly, to those known in the art as pulverizing systems and devices. This invention provides methods and apparatuses for an improved disc mill assembly that utilizes a tapered flywheel and water jacket in conjunction with planar grinding disk cutting devices to create a tapered grinding channel.

Abstract: Disclosed are digital cameras adapted to capturing whiteboard images, and methods. Embodiments of the cameras incorporate processing firmware to create clear whiteboard images from digital images. Embodiments may also include a specialized lens for correcting for perspective effects, an interface for connection to a computer network, and provisions to facilitate semi-permanent mounting. Embodiments may also omit features commonly found on conventional digital cameras, such as a viewfinder; a memory card slot; a wide range of focus and shutter speeds; and on-camera controls; such that the cost of the whiteboard camera is reduced and the camera is rendered unattractive to theft.

Abstract: There is a urinary transfer system and associated process that includes a urinal capable of receiving urine from a patient, urine holding container, a first conduit connected between the urinal and the urine holding container, a pump, and a second conduit connected between the urine holding container and the pump. Preferably, there is a retainer that is associated with the urinal and a removable lid associated with the urine holding container. The urinary transfer system can be powered by any type of electrical power supply and/or battery. Optimally, there is a receiver electrically connected to the pump to be able to turn the pump on and off and can preferably control the operation of the pump based on input received from a transmitter. An external male catheter can also be utilized in conjunction with the urinary transfer system.
