  • Patent number: 10835676
    Abstract: A push button safety injector includes a housing having a proximal end, a distal end spaced from the proximal end, and a longitudinal axis. An injection ram is positioned along the longitudinal axis and configured to actuate a fluid chamber. The injection ram is biased toward the distal end in an initial position. A sliding member is configured to retain the injection ram in the initial position. A safety member confines radial movement of the sliding member in the initial position and allows radial movement of the sliding member in an armed position. A button is moveable between an initial extended position and a depressed position. The button is engagable with the sliding member and configured to move the sliding member radially in the armed position. The sliding member releases the injection ram when the button is in the depressed position.

  • Patent number: 7549211
    Abstract: A method for de-tabbing a dielectric tab extending between and bonded to first and second stainless steel portions of a disk drive head suspension component. Exemplary first and second stainless steel portions are a flexure base region and a flexure tongue. The method includes applying laser energy to the dielectric tab. The laser energy is characterized by one or more parameters, e.g., a pulse width and/or an energy density, causing de-bonding of the dielectric tab from the first and second stainless steel portions.
