  • Patent number: 7420864
    Abstract: Embodiments of the invention generally provide methods and apparatuses for updating a temperature measurement. In one embodiment, the temperature measurement is performed by a temperature sensor using one or more reference signals. A signal to update the temperature measurement is received. A determination is made of whether the clocked standby mode signal has changed within a period of time prior to receiving the signal to update the temperature measurement. If the clocked standby mode signal has changed within the period of time, the signal to update the temperature sensor is masked. If the clocked standby mode signal has not changed within the period of time, the temperature measurement is updated using the signal to update the temperature measurement.

  • Patent number: 7345931
    Abstract: A method and circuit for controlling an output reference voltage generated by a reference voltage generator disposed on a memory device are provided. A signal for enabling a clocked standby mode of the memory device is received. If the signal indicates that the memory device is in the clocked standby mode, a first reference voltage is generated as the output reference voltage of the reference voltage generator using a first voltage. If the signal indicates that the memory device is not in the clocked standby mode, a second reference voltage is generated as the output reference voltage of the reference voltage generator using a second voltage.

  • Patent number: 7205829
    Abstract: A method and apparatus for controlling a voltage generator of a memory device are provided. In one embodiment, a first clock signal and a second clock signal are provided. The voltage generator is selectively enabled in conjunction with the first clock signal when a period of the first clock signal is less than a period of the second clock signal and the voltage generator is selectively enabled in conjunction with the second clock signal when the period of the second clock signal is less than the period of the first clock signal.

  • Patent number: 7177219
    Abstract: A method and apparatus for controlling a voltage generator of a memory device are provided. A temperature of the memory device is measured. If the measured temperature is outside a threshold temperature range, the memory device is allowed to be placed in a clocked standby mode (CSM), whereby the voltage generator is selectively enabled with a clock signal. If the measured temperature is within a threshold temperature range, the memory device is prevented from being placed in the clocked standby mode (CSM).

  • Publication number: 20060293147
    Abstract: A closed loop adaptive fluid control system and method for use in hydraulic applications monitors one or more fluid characteristics, such as pressure, flow rate, accumulation time in an actuator, fill volume, etc., and compares the characteristic with a target response. A fluid characteristic sensor detects at least one fluid characteristic at a hydraulically-actuated device that is actuated by a electrically-operated. The sensor sends a device signal corresponding to the actual sensed characteristic to an electronic controller, which compares the device signal with a target response. The controller then identifies any differences between the device signal and the target response and provides a feedback signal to the electrically-operated valve to adjust the current to the valve, which in turn adjusts the electrically-operated valve so that the device signal corresponding to the sensed characteristic at the device converges toward the target response.

  • Publication number: 20060052959
    Abstract: The present invention relates to a method of analyzing accuracy of linear sensor output based on a theoretical prediction of the output model. The method comprises steps of: analyzing a statistically significant number of linear sensors to obtain operating profiles at two or more operating conditions; individually testing a linear sensor to obtain at least four data points; developing a theoretical prediction of the output model for each operating condition from the four data points; and comparing accuracy of the relationship between the theoretical prediction of the output model to sensor output in the operating profile corresponding to a given input for the same operating condition. Also disclosed are calibration algorithms associated therewith, as well as mechatronic units and further assemblies therefrom.

  • Publication number: 20060032541
    Abstract: An electro-hydraulic manifold assembly with a plurality of solenoid operated valves disposed on a manifold block and each operable to control pressure from the inlet to a separate outlet. Sensing ports are provided in each outlet with a pressure sensor sealed over the sensing port for providing a signal indicative of the sensed pressure. The pressure sensors are mounted on a interface and electrically connected to the interface. The interface has slots therein which permit the frame to be simultaneously electrically connected by bayonet connection to the terminals on each solenoid valve as the transducers are sealed over the sensing ports and the interface attached to the manifold block.
