  • Patent number: 11969554
    Abstract: A haptic stimulator includes a multilayer sheet with a piezoelectric or electroactive polymer layer adapted to mechanically deform upon application of voltage, the multilayer sheet secured to a substrate, and a source of electrical stimulation coupled to drive electrodes on the polymer layer with an AC signal to vibrate the polymer layer. In particular embodiments, the polymer contains polyvinylidene fluoride, and electrodes are patterned to control local electric fields. Another haptic stimulator has first and second electrodes with an air gap and an insulating sheet between first and second electrodes, with an AC voltage driver connecting to the electrodes. In a method of providing haptic stimulation to skin an alternating current supply drives first and second electrodes, the electrodes disposed upon either a piezoelectric or electroactive polymer sheet, vibrating the polymer layer by driving the electrodes; and coupling vibrations of the polymer layer to the sensate skin.

  • Publication number: 20190006339
    Abstract: An integrated fan-out wafer level package houses a semiconductor package having a first semiconductor die encapsulated by a dielectric compound. A plurality of redistribution layers are formed on a first side of the semiconductor package which are in electrical contact with contact pads of the first semiconductor die. A plurality of solder balls located on the first side of the semiconductor package is electrically connected to the contact pads of the semiconductor die via the redistribution layers. A second semiconductor die is further attached to the first side of the semiconductor package and is electrically connected to the contact pads of the first semiconductor die via the redistribution layers.

  • Publication number: 20090026722
    Abstract: A system is disclosed for a baggage handling device to be placed between a weighing platform and a conveyor system at an airline check-in counter. The baggage handling device includes a cart portion further comprising a box frame, a set of wheels, a set of rollers, a latch mechanism and a set of handle rods, and a rail portion further comprising a rectangular frame with a set of rails and two sets of unlatch mechanisms. The set of wheels is aligned with and placed above the set of rails such that the cart portion moves along the rail portion. The latch mechanism is provided to facilitate a locked position to allow safe loading of baggage onto the cart portion.
