Abstract: An integrated circuit for a smart card may include a transceiver and a controller for cooperating with the transceiver to receive operating requests from a host device. The controller may perform smart card operations based upon respective operating requests. Moreover, the controller also may cooperate with the transceiver to receive at least one advance request from the host device to indicate that at least one operating request will follow. By way of example, the standby operation may include loading data in at least one buffer, which may be sent to the host device based upon receiving the at least one operating request. Other standby operations may include disabling data transmission to the host device, such as when the communications bus of the host device is preoccupied, and ceasing performing a current smart card operation to allow a higher priority smart card operation to be performed, for example.

Abstract: A testable, pulse-triggered static flip-flop. A pulse generator produces a data enable trigger pulse only when a test enable input is low, and a scan test enable trigger pulse only when a test enable input is high. The data enable trigger pulse controls the data input to the flip-flop, while the scan test enable trigger pulse controls the scan test input to the flip-flop. The flip-flop consists of a selection circuit comprised of two latches, each including an inverter and a transmission gate. One latch receives the data input and the other latch receives the scan test input. The data enable trigger pulse controls the transmission gate receiving the data input, and the scan test trigger pulse controls the transmission gate receiving the scan test input. The flip-flop also includes a keeper circuit consisting of a feedback inverter and a static latch.

Abstract: There is disclosed a voltage controlled oscillator (VCO) that receives nullV(IN) and nullV(IN) control voltages and outputs a VCO output signal having an oscillation frequency determined by the nullV(IN) and nullV(IN) control voltages. The VCO comprises: 1) a storage capacitor charged linearly by a constant charge current and discharged linearly by a constant discharge current; 2) a comparator for comparing the storage capacitor voltage to an upper threshold voltage and a lower threshold voltage. The comparator output drops to a negative saturation voltage (nullV(SAT)) when the storage capacitor voltage rises above the upper threshold voltage and rises to a positive saturation voltage (nullV(SAT)) when the storage capacitor voltage drops below the lower threshold voltage. The VCO also comprises: 3) a constant charge current source for injecting the constant charge current into the storage capacitor when the comparator output rises to the positive saturation voltage; and 4) a constant discharge current source for draining the constant discharge current from the storage capacitor when the comparator output drops to the negative saturation voltage.

Abstract: Clustered VLIW processing elements, each preferably simple and identical, are coupled by a runtime reconfigurable inter-cluster interconnect to form a coprocessor executing only those portions of a program having high instruction level parallelism. The initial portion of each program segment executed by the coprocessor reconfigures the interconnect, if necessary, or is skipped. Clusters may be directly connected to a subset of neighboring clusters, or indirectly connected to any other cluster, a hierarchy exposed to the programming model and enabling a larger number of clusters to be employed. The coprocessor is idled during remaining portions of the program to reduce power dissipation.

Abstract: A finger imaging system for receiving the finger of a person being fingerprinted by an automated fingerprint reader. The system includes a finger imaging device having a finger receiving portion for receiving the finger to be fingerprinted. Extending outward from the finger receiving surface is a locator bar that is located to engage a crease of the subject finger when it is in approximately the desired position. The locator bar may be fixed by or movably attached to the finger receiving surface, or may protrude through the finger receiving surface, possibly being attached to an interior movement mechanism. The locator bar may clean the finger as it is being positioned, and may include sensors for sensing non-image information to verify the legitimacy of an offered finger. The locator bar may also include a shunt for diverting unwanted static electricity stored on the finger before it is positioned for fingerprinting.
