  • Patent number: 9161142
    Abstract: Push button insertion tool is a device used to help clean and install a receiver-in-the-canal hearing instrument into the ear. This product may be in the shape of a tapered tube, resembling a writing pen. The far end of the tube may be shaped to fit receivers of various sizes, and may include a slot on the side through which the microphone wire may extend. On the other end of the tube may be a push button. When pushed, it moves a rod through the tube to a push plunger, which inserts the receiver out of the tube and into the ear canal. A return spring and guide pin on the far end is designed to retract the push rod back to starting position.

  • Patent number: 7959368
    Abstract: An ink cartridge structure includes a resilient device coupled to an ink cartridge for absorbing impact energy acting on the ink cartridge for protection of the ink cartridge. The resilient device includes a connection bar mounted to the ink cartridge and is coupled to a retention bar that is accessible by a user with a resilient element therebetween so that the resilient element provides cushioning to the ink cartridge. The connection bar is partially fit into a hollow portion of the retention bar and forms a vent hole that is in communication with the ink cartridge so that when the retention bar, under the resilient support by the resilient element, is manually moved reciprocally with respect to the connection bar, air is pumped, through the vent hole, into the ink cartridge to force the ink contained in the ink cartridge to ward a writing tip.

  • Patent number: 6914596
    Abstract: A Personal Digital Assistant (PDA) with retractable stylus comprises a retractable stylus, a housing, a stylus slot, and a push portion, wherein a contact pad is attached to the inner side of the push portion. The retractable stylus comprises a pen shaft having a release button, a pen body having an opening, and a spring situated inside the pen body. When an external force is applied to the pen shaft downward, the spring is compressed until the opening holding the release button; thus, the stylus is shortened. When the release button is set free from the opening, the spring elasticity ejects the pen shaft upward; thus, the stylus returns to the full-length condition. If the stylus is kept in the stylus slot, an external force applied to the push portion can make the contact pad press the release button; so the pen shaft is ejected upward by spring elasticity.
