Abstract: A precharge control device includes a pulse generator, a bank address controller, and a precharge signal generator. The pulse generator generates a write precharge signal in response to a write burst end signal activated after a write burst operation and a read precharge signal in response to a read burst end signal activated after a read burst operation. The bank address controller generates a write address and a read address designating an address for the precharge operation in response to a write bank address and a read bank address. The precharge signal generator generates a precharge signal for performing the precharge operation in a bank selected in response to the write address when the write precharge signal is activated, or generates a precharge signal for performing the precharge operation in a bank selected in response to the read address when the read precharge signal is activated.

The sub-chamber contains a fuel tank of the motor vehicle and is delimited by the fuel tank vent valve.

Abstract: A physically unclonable function (PUF) is implemented in a plurality of SRAM cells. In a method for generating a PUF response, a logic zero is first written to all the SRAM cells of the PUF. A bit line coupled to the storage node that stores the logic zero of each SRAM cell is biased to a predetermined voltage. The bit lines are then selected for an evaluation read operation. During the evaluation read, a read current of one of the bit lines from one column is converted to a first voltage and a read current of another bit line of another column is converted to a second voltage. The first voltage is then compared to the second voltage. A logic state of a bit of the PUF response is determined as a result of the comparison. The logic bit may be provided to the input of a parallel-in serial-out shift register. There may be a comparator for each logic bit, or a few comparators may be shared between the logic bits. The PUF response may be used to provide a signature for the data processing system.

Abstract: Filter circuitry is constituted by transversal filters which are connected in parallel to each other. The transversal filters change amplitude and a phase of an input digital signal Xin[n·Ts] and output different digital signals X1[n·Ts], X2[n·Ts], and X3[n·Ts] as respective resulting digital signals whose amplitude and phase have been changed. A phase frequency computer computes a phase ?X[n·Ts] and a frequency fX[n·Ts] of the input digital signal Xin[n·Ts] by performing phase computation and frequency computation using the digital signals X1[n·Ts], X2[n·Ts], and X3[n·Ts] output by the transversal filters.

Abstract: Embodiments herein provide detection of contamination at one or more contacts of a sensor system. The sensor system includes a sensor assembly and an electronics assembly communicatively coupled together by one or more contacts. The sensor assembly passes a sensor signal to the electronics assembly for further processing. The electronics assembly includes a detection contact for detecting contamination on or near one or more contacts of the sensor assembly and/or the electronics assembly. A switch selectively couples the detection contact to a bias voltage during a measurement mode and to a reference voltage during a detection mode, the reference voltage being different from the bias voltage. A method of contamination detection includes switching the electronics assembly between the measurement mode and the detection mode, and monitoring for a change in the output signal received by the electronics assembly.

Abstract: Accelerometer data that is received from multiple accelerometers can be synchronized to identify a known movement. This synchronization occurs in real time as the accelerometer data is received from the multiple devices. The orientation of an accelerometer can be compensated for dynamically. By dynamically compensating for the orientation, the user can wear the accelerometers in various orientations without needing to calibrate a portable computing device to account for a particular orientation. Portable devices can have one or more detachable accelerometers. The accelerometers can be detached and placed at virtually any location of a user's body to allow for the detection of custom movements.

Accordingly, the drilling operation is performed using at least the axial survey sensor based on the calibration parameter.

Abstract: Discussed herein are a sensor-network system and a method thereof for detecting and isolating faults occurring in sub-systems and sensors included in the network. The sub-systems and the sensor measurements are subject to noise and disturbances. A bank of Kalman-filters (KF) is used to detect and isolate the faults. Each KF is driven by either a pair of consecutive sensor measurements or a pair including a reference input and a sensor measurement. The KF residual is computed for each measurement pair and is a reliable indicator of a fault in subsystems and sensors located in the network.

The first memory and the second memory supply a fourth current and a fifth current, respectively, when a potential corresponding to second analog data is supplied. By subtracting the third current from a differential current between the fourth current and the fifth current, a current that depends on the sum of products of the first analog data and the second analog data is obtained. By providing a plurality of product-sum operation circuits that can be freely connected, a hierarchical neural network can be formed.

Abstract: Apparatuses and techniques are described for temperature dependent erase in non-volatile storage. In one aspect, select gate voltage magnitude depends on temperature. This temperature dependent select gate voltage may be applied to a control gate of a select transistor while applying an erase voltage to a bit line and/or source line coupled to the select transistor.

In one aspect, a control circuit increases the duration of the erase voltage that is applied to the source line and/or the bit line at lower temperatures. In one aspect, the magnitude of the first erase voltage in a sequence depends on the present temperature.
