  • Patent number: 10418438
    Abstract: A capacitor structure may include a lower conducting layer (e.g., poly 1 layer) and an upper conducting layer (e.g., overlying poly 2 layer), which define an anode and cathode, and a dielectric layer (e.g., an ONO layer stack) located between the upper conducting layer and the lower conducting layer, wherein a portion of the dielectric layer (e.g., at least the nitride layer of the ONO layer stack) extends beyond a lateral edge of the upper conducting layer. A method forming such capacitor structure may utilize a spacer adjacent the lateral edge of the upper conducting layer and over the first portion of the dielectric layer, performing an etch to remove a first portion of the dielectric layer but protect a second portion located below the spacer and extending laterally beyond an edge of the upper conducting layer.

  • Patent number: 8988142
    Abstract: High voltage rated isolation capacitors are formed on a face of a primary integrated circuit die. The isolation capacitors AC couple the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitors DC isolate the primary integrated circuit from the second integrated circuit die. Isolated power transfer from the first voltage domain to the second voltage domain is provided through the high voltage rated isolation capacitors with an AC oscillator or PWM generator. The AC oscillator voltage amplitude may be increased for an increase in power through the high voltage rated isolation capacitors, and a larger value capacitor in the second voltage domain may provide for peak current demand from circuits in the second voltage domain.

  • Publication number: 20140134574
    Abstract: Laser target practice using an ultra-violet light emitting laser that is pulsed on when a weapon trigger is pulled. The UV laser light pulse illuminates a spot on a target having a coating of phosphorescent material on a face thereof. The phosphorescent material within the illuminated spot glows for a certain time thereby visually indicating a location of the spot on the target. The UV laser light pulse may also illuminate a spot on a target having a photochromic paint coatings on a face thereof. The photochromic paint coatings within the illuminated spot changes color thereby indicating a location of the spot on the target.

  • Patent number: 8164416
    Abstract: A remote keyless entry (RKE) transponder has a programmable selective wake-up filter for determining whether the RKE transponder should wake-up to process a received signal. The wake-up filter correlates the timing of an input signal's carrier amplitude on and off time periods to a predefined programmable time period profile for a desired signal which has a certain carrier on time (time period on) and a certain carrier off time (time period off) arranged into a coded “header.” When a received signal matches the predefined time period profile, then the RKE transponder will wake-up to process the incoming signal data. The predefined time period profile may be programmable and may be stored in a header configuration register. Each RKE transponder has unique predefined time period on and time period off profiles.

  • Patent number: 7885047
    Abstract: Adaptive electrostatic discharge (ESD) protection of a device interface has very good ESD robustness when it is handled or when installed into or removed from a system. And has robust immunity to DPI, electromagnetic interference (EMI) and the like, when it is operational in a system. There is a significant capacitive coupling between the drain and gate of a ESD protection metal oxide semiconductor (MOS) device to enhance ESD protection and lower snap back voltage thereof whenever there is no (or a low level) DPI on the external connection to be protected. Whereupon when a significant DPI/EMI signal is detected on the external connection, the capacitive coupling between the drain and gate of the MOS ESD protection device is disconnected, bypassed or attenuated so that DPI/EMI immunity of the device is enhanced.
