    摘要: Correcting a temperature measurement of a target sensed at one temperature sensor in an asset tracking device by using another temperature sensor. The asset tracking device includes at least one heat source that affects the temperature sensor for sensing the temperature of the target. The other temperature sensor measures temperature at a location in the asset tracking device. The relationships between an actual temperature of the target and the temperature measured at the two sensors are established through experiments or model. Using the relationships, the measured temperature of the target can be corrected to obtain a corrected temperature of the target.

    摘要: An LCOS chip may have a pixel divided into an outer subpixel and an inner subpixel. A driver may independently drive the subpixels. The driving technique may be pulse-width modulation. Because of the pixel is divided into subpixels, pulses of short widths that drive an undivided pixel may be replaced with pulses of longer duration. In an alternative embodiment, the pixel is not divided into subpixels. The driving technique may be a combination of pulse width and pulse height modulation. The waveform may replace pulses of short widths with pulses of longer duration and reduced voltage levels.

    摘要: A true north heading is determined by using gyroscopes of differing accuracy and orienting a gyroscope of a higher accuracy to a direction that is more sensitive to azimuth change (e.g., an east/west direction). A gyroscope with a lower accuracy is placed perpendicular to the gyroscope with a higher accuracy and can be oriented towards a north or south direction. The gyroscopes may be placed on a rotatable platform to properly orient the gyroscopes. The higher-accuracy gyroscope may be implemented by using multiple gyroscopes oriented in the same direction.

    摘要: A system includes a power supply, a meter coupled to the power supply, and a controller. The meter takes a measurement of a parameter that is approximately proportional to the power consumed from the power supply by at least a portion of a computer system. This parameter may include, for example, the current or voltage between the power supply and the portion of the computer system, or the duty cycle of a switching signal in the power supply. This measurement is then used by the controller to determine if the power consumed by the portion of the computer system reaches a threshold, and if so, the controller sends a throttle signal. A system and method such as this may be found useful to reduce the risk of a computer system blowing a fuse or tripping a circuit breaker.

    摘要: A spatially distributed MEMS inertial sensor array is designed to reduce or cancel measurement errors and to increase the signal detection accuracy. By combining the measurements from a pair of sensors having sensing axes in two different, non-orthogonal directions, the correlated error due to the environmental changes are cancelled or reduced and the uncorrelated random noise is also reduced by the square root of two. By sequentially sampling the sensor array in the time domain, the number of the ADC circuits can be largely reduced. A two dimensional signal processing method is used to process the sensor array output data, in order to further reduce the remaining errors. Namely, one dimension uses the outputs from multiple spatially distributed sensor sets and the other dimension is the time domain. The signal to noise ratio is increased by using the signal correlation in both the spatial domain and the time domain.
