  • Patent number: 8605054
    Abstract: A touch screen system includes a capacitive touch screen (1) including a plurality of row conductors (7-1,2 . . . n) and a column conductor (5-1). A plurality of cotemporaneous orthogonal excitation signals (S1(t), S2(t) . . . Sn(t)) are simultaneously driven onto the row conductors, respectively. The capacitively coupled signals on the column conductor may be influenced by a touch (10) on the capacitive touch screen. Receiver circuitry (50) includes a sense amplifier (21-1) coupled to generate an amplifier output signal (r1(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry (35) determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal.

  • Patent number: 8338208
    Abstract: A MEMS may integrate movable MEMS parts, such as mechanical elements, flexible membranes, and sensors, with the low-cost device package, leaving the electronics and signal-processing parts in the integrated circuitry of the semiconductor chip. The package may be a leadframe-based plastic molded body having an opening through the thickness of the body. The movable part may be anchored in the body and extend at least partially across the opening. The chip may be flip-assembled to the leads to span across the foil, and may be separated from the foil by a gap. The leadframe may be a prefabricated piece part, or may be fabricated in a process flow with metal deposition on a sacrificial carrier and patterning of the metal layer. The resulting leadframe may be flat or may have an offset structure useful for stacked package-on-package devices.

  • Patent number: 8304274
    Abstract: Semiconductor-centered MEMS (100) integrates the movable MEMS parts, such as mechanical elements, flexible membranes, and sensors, with the low-cost device package, and leaving only the electronics and signal-processing parts in the integrated circuitry of the semiconductor chip. The package is substrate-based and has an opening through the thickness of the substrate. Substrate materials include polymer tapes with attached metal foil, and polymer-based and ceramic-based multi-metal-layer dielectric composites with attached metal foil. The movable part is formed from the metal foil attached to a substrate surface and extends at least partially across the opening. The chip is flip-assembled to span at least partially across the membrane, and is separated from the membrane by a gap.

  • Patent number: 6177772
    Abstract: A circuit and method for braking a disk drive when a power fault occurs has a circuit (10) for producing an output signal (28) indicating that the motor of the disk drive has slowed at least to a predetermined rotational speed after the occurrence of the power fault. The components of the circuit (10) may be integrated onto the same integrated circuit as the motor driving circuitry or head retract circuitry. During the time between the occurrence of the power fault and the time the disk drive has slowed to the predetermined rotational speed, the read/write head mechanism (17) is retracted. A braking circuit then brakes the disk drive when the output signal (28) indicates that the motor has slowed, at least to the predetermined rotational speed. The circuit for producing an output signal indicating that the motor has slowed at least to the predetermined rotational speed is actuated by the back-emf (14) generated by the motor failing below a predetermined level.
