  • Patent number: 8872240
    Abstract: The present invention exploits the combination of the amplification, provided by the integration of a FET (or any other three terminal active device), with the signal modulation, provided by the MEM resonator, to build a MEM resonator with built-in transistor (hereafter called active MEM resonator). In these devices, a mechanical displacement is converted into a current modulation and depending on the active MEM resonator geometry, number of gates and bias conditions it is possible to selectively amplify an applied signal. This invention integrates proposes to integrate transistor and micro-electro-mechanical resonator operation in a device with a single body and multiple surrounding gates for improved performance, control and functionality. Moreover, under certain conditions, an active resonator can serve as DC-AC converter and provide at the output an AC signal corresponding to its mechanical resonance frequency.

  • Patent number: 8863096
    Abstract: A symbolic execution task is dynamically divided among multiple computing nodes. Each of the multiple computing nodes explores a different portion of a same symbolic execution tree independently of other computing nodes. Workload status updates are received from the multiple computing nodes. A workload status update includes a length of a job queue of a computing node. A list of the multiple computing nodes ordered based on the computing nodes' job queue lengths is generated. A determination is made regarding whether a first computing node in the list is underloaded. A determination is made regarding whether a last computing node in the list is overloaded. Responsive to the first computing node being underloaded and the last computing node being overloaded, a job transfer request is generated that instructs the last computing node to transfer a set of one or more jobs to the first computing node.

  • Patent number: 8836368
    Abstract: New logic blocks capable of replacing the use of Look-Up Tables (LUTs) in integrated circuits, such as Field-Programmable Gate Arrays (FPGAs), are disclosed herein. In one embodiment, the new logic block is an AND-Inverter Cone (AIC), which is a binary tree including one or more AND gates with a programmable conditional inversion and a number of intermediary outputs. Compared to LUTs, AICs are richer in terms of input and output bandwidth, because the area of the AICs grows only linearly with the number of inputs. Also, the delay grows only logarithmically with the input count. The new logic blocks can map circuits more efficiently than LUTs, because the AICs are multi-output blocks and can cover more logic depth due to the higher input bandwidth.

  • Patent number: 8788042
    Abstract: A preferred frequency is identified, being usable to stimulate a neurological target within a mammalian body using at least one microelectrode positioned at or near the target. To establish efficient and effective stimulation, an impedance analyzer is provided for measuring electrical impedance values indicative of a microelectrode-tissue interface across a range of different frequencies. A preferred one of the measured electrical impedance values is identified as being closest to a pure resistance. The neurological target can then be stimulated at or near the frequency associated with the preferred impedance value (peak resistance frequency), thereby promoting desirable traits, such as optimum charge transfer, minimum signal distortion, increased stimulation efficiency, and prevention of microelectrode corrosion. The peak resistance frequency can be used to determine an preferred pulse shape.
