  • Publication number: 20090315525
    Abstract: A voltage reference module of an integrated circuit device includes a current source to apply a current to a set of voltage cells, thereby generating a voltage drop across each cell. The voltage cells are configured such that the individual voltage drop associated with each cell in response to the application of the current is relatively stable over a temperature range. The voltage reference module generates a voltage based on the voltage drops across the voltage cells, and therefore the generated voltage is also stable over the temperature range. Bypass switches can be connected across each voltage cell whereby the switches can be individually opened and closed to include or exclude cells in generation of the reference voltage. In an embodiment, the switches are set during a trimming process for the integrated circuit device so that the voltage reference module provides a specified voltage.

  • Publication number: 20090243655
    Abstract: A transceiver suitable for interfacing a logic device to a shared bus includes a transmit node that receives an input signal from the logic device and an I/O node, that is coupled to the shared bus. The transceiver may be designed for use with a shared-bus, single master, multiple slave architecture, e.g., a Local Interconnect Network (LIN). In a LIN compliant implementation, the transceiver may be suitable for use in at least some types of automobiles and other motorized vehicles. Control logic coupled to the transmit node may assert a current driver enable signal in response to detecting an assertion of the input signal. A current driver of the transceiver is configured to draw a time varying driver current from the shared bus node after detecting an assertion of the current driver enable signal. The driver current may cause a sinusoidal transition of the shared bus voltage.

  • Publication number: 20080123238
    Abstract: A device includes a current source circuit to separately provide a first current and a second current and a thermal detection device coupleable to the output of the current source circuit. The device further includes a voltage detection circuit to provide a first indicator of a first voltage representative of a voltage at the thermal detection device in response to the second current and a second indicator of a second voltage representative of a voltage difference between the voltage at the thermal detection device in response to the second current and a voltage at the voltage detection device in response to the first current. The device further includes a temperature detection circuit to provide an over-temperature indicator based on the first indicator and the second indicator, wherein an operation of a circuit component of the device can be adjusted based on the over-temperature indicator.

  • Publication number: 20080055048
    Abstract: A communication link is established between the smart card and a computer using a valid smart card communication protocol. A smart card communication device determines the valid smart card communication protocol used by a smart card by polling a communication channel using a plurality of smart card communication protocols until a valid acknowledgment message is received. A radio frequency circuit is configured to communicate with the smart card using the valid smart card communication protocol. A digital signal processor having at least two demodulators demodulates an incoming data stream produced by the receiver in accordance with the valid smart card communication protocol in a dynamically reconfigurable manner.

  • Patent number: 7192925
    Abstract: The present invention provides isoformes from a peptide family belonging to South American scorpion Tityus serrulatus that acts as hypotensive agents by potentiating Bradykinin and, therefore, can be used as anti-hypertensive drugs. A peptide was firstly isolated from Tityus serrulatus venom and showed a strong and long-lasted hypotensive activity when tested in rats. This peptide was first named TsHpt-I (Tityus serrulatus Hypotensin-I). Also, three more highly similar isoformes were identified and revealed a peptide family with very close primary structure. They were named TsHpt-II, TsHpt-III and TsHpt-IV.

  • Patent number: 6974892
    Abstract: A sanitary napkin having a first transverse end and an opposite second transverse end defining therebetween a length and a plurality of varying widths along its length, the widths being perpendicular to the length, including; (i) a first width located substantially between ? and ½ of the length as measured from the first transverse, (ii) a second width located substantially from ? to ½ of the length as measured from the second transverse end, (iii) the first width being the maximum width of the absorbent portion, the second width being less than or equal to the first width; and (iv) a central region intermediate the first width and the second width, the central region having a maximum width that is less than or equal to the first width.
