Abstract: A device that encapsulates functions necessary to sanitize an electronic system after detecting tampering or when user zeroization occurs. The device includes a FPGA, sensors, external tamper sensors, a battery, interfaces or discrete signals required to execute sanitization of hard drives, flash, registers, etc. The device issues a sanitization response through interface commands Manual sanitization (zeroization) can be achieved two ways, locally or through a remote zeroize button/switch/discrete. The sanitization response is activated through monitoring the tamper sensors. The sanitization response will destroy stored data and encryption keys before they can be compromised. The sanitization response could produce a notification that an event has occurred. The system can provide data protection without main line or standby power. Sensors could include, chassis intrusion switches, motion detectors, radiation sensors, light sensors, temperature sensors, magnetic sensors, or other external inputs.

Abstract: A system and method for sanitizing a mass storage device on a host computer which includes a control system which receives input which starts a process of sanitizing a mass storage device, which includes a switch which isolates the mass storage device from an input interface that is used in normal operations and provides signals from an alternate input to the mass storage device to sanitize the mass storage.

Abstract: Embodiments of systems and methods include a sensor subsystem (e.g., within a container-mounted device) that produces a sensor output, and a processing system that implements a state machine. Upon entry into a first state, the processing system starts a timer, and while in a second state, the processing system waits for a specific sensor output value to be received. The processing system transitions from the first state to the second state upon expiration of the timer, and the processing system transitions from the second state to the first state when the sensor output corresponds to the specific sensor output value. When the state machine is in the second state, the output device produces a human-perceptible indicia configured to prompt a human user to perform an action that is likely to cause the sensor to produce the sensor output that corresponds to the specific sensor output value.

Abstract: The present disclosure provides several systems. In general, it provides E-field sensor systems that utilize at least one electrode 100 adapted for creating an E-field in an area 210 within a detection volume where fluid presence 400 or presence of a solid body 300 is to be detected. The electrical field sensor is configured to generate a detected signal responsive to a change in capacitance of the electric field, and is communicatively coupled to the electrode 100. In addition, a processor 275 is configured to determine a quantitative measure of a fluid or solid body within the detection volume in accordance with a capacitive relationship with the detection volume. Described are examples of the system for fluid presence detection, fluid level measurement and measurement of proximity to a solid object.

Abstract: A method and apparatus for improving microprocessor data acquisition. Noise in analog signals is removed by a low pass filter with a variable cutoff frequency controlled to cut off all frequencies above a frequency range of interest. The filtered signal is sampled by an analog-to-digital converter at a sampling rate which is variable and controlled to sample at a rate that is at least two times the low pass filter cutoff frequency thereby reducing the rate at which data is passed to a microprocessor and reducing the need for speed in the microprocessor's processing.
