  • Patent number: 9955443
    Abstract: A system for synchronizing nodes in a wireless network comprises a first node and a second node. The first node comprising a transmitter, a receiver, and a first time keeper. The second node comprising a transmitter, a receiver, a second time keeper, a timing error measurer for making a timing error measurement between the first time keeper and the second time keeper. The second timekeeper is adjusted to target minimizing the timing error measurement.

  • Patent number: 9658118
    Abstract: A precision temperature sensing system includes a heater and a sensing element disposed on a semiconductor substrate. A power source drives the heater on a periodic basis according to a received clock signal. The sensing element senses the heat emitted by the heater and diffused through the semiconductor substrate. Processing circuitry coupled to the sensing element adjusts a phase of the periodic heater driving signal based on the heat sensed by the sensing element. The processing circuitry determines a temperature based on a thermal diffusivity (TD) of the semiconductor substrate, the adjusted value of the phase, and a known distance between the heater and the sensing element. A second temperature sensor can be disposed on the same substrate as the precision temperature sensing system, and calibrated based on temperature measurements obtained while applying a reference frequency signal to the precision sensing system.

  • Patent number: 8924633
    Abstract: The erasing of data stored in a nonvolatile memory is performed using multiple partial erase operations. Each partial erase operation has a time duration that is shorter than the minimum time duration of an erase operation that is needed to reliably erase the data stored in the storage location. However, the sum of the time durations of the multiple partial erase operations is sufficient to reliably erase the data in the storage location. In one example, during a partial erase operation, a voltage is applied to a memory storage transistor to remove some, but not necessarily all, of the charge stored on a charge storage layer of the transistor. Following multiple partial erase operations, sufficient charge is removed from the charge storage layer to ensure reliable data erasure.

  • Patent number: 8699406
    Abstract: A system for maintaining synchronization of nodes in a wireless network comprises a child node and a parent node. The child node comprising a transmitter, a receiver, and a first time keeper. The parent node comprising a transmitter, a receiver, a second time keeper. The parent node receiver is active for a guardband and wherein the guardband is adjusted to maintain synchronization of the parent node with the child node.
