Abstract: A control surface tracks an individual cacheline in the original surface for frequent data values. If so, control surface bits are set. When reading a cacheline from memory, first the control surface bits are read. If they happen to be set, then the original memory read is skipped altogether and instead the bits from the control surface provide the value for the entire cacheline.

Abstract: A calibration method for calibrating a compass system suitable for use in a vehicle includes sampling data points of a magnetic field with a magneto-responsive sensor and processing output signals of the sensor via compass circuitry. The compass circuitry includes an analog-to-digital converter for converting analog signals of the sensor to digital signals and a digital-to-analog converter for converting digital signals to analog signals that are supplied to the sensor for adjusting the sensor. The output signals of the sensor are adjusted to be within an operable range of an analog-to-digital converter via an initial calibration mode. After completion of the initial calibration mode, output signals of the sensor are processed to determine when the output signals are outside a range of the analog-to-digital converter. An output of a digital-to-analog converter is adjusted to reposition the output signals of the sensor to be within the range of the analog-to-digital converter.

Abstract: A compass compensation system is provided for automatically and continuously calibrating an electronic compass for a vehicle, without requiring an initial manual calibration or preset of the vehicle magnetic signature. The system initially adjusts a two axis sensor of the compass in response to a sampling of at least one initial data point. The system further calibrates the compass by sampling data points that are substantially opposite to one another on a plot of a magnetic field and averaging an ordinate of the data points to determine a respective zero value for the Earth magnetic field. The system also identifies a change in magnetic signature and adjusts the sensor assembly.

Abstract: A safety sensing and/or release system for a closed compartment of a vehicle is operable to detect an occupant within the vehicle compartment. The system may be operable to sense ambient conditions in the vehicle compartment, and may generate a control signal in response to the sensed conditions. The system may actuate indicators to notify operators of the vehicle that there is a person or animal detected in the compartment. Optionally, the system may open the vehicle compartment in response to a detection of an occupant and the sensed conditions. The safety system includes a false trigger protection means that limits or reduces false detections of a person or animal within the compartment.

The control may be selectably locked in response to an input signal indicative of at least one of the vehicle ignition being on and the vehicle moving, in order to prevent the compartment from unexpectedly opening while the vehicle is moving.
