Abstract: Described is a system and/or method for displaying the location of a ferromagnetic object in a living organism by using a surgical probe. The surgical probe has a shaft with three-dimensional magnetoresistance sensors located on a distal end configured for insertion into the living organism and three-dimensional magnetoresistance sensors located on a proximal end that stays outside of the living organism. The system comprises a display configured to show the relative location of a detected ferromagnetic object to the tip of the probe in a simulated three-dimensional view on a two-dimensional display.

Abstract: A system and/or method for detecting a ferromagnetic object during surgery comprises a probe tip magnetoresistance device configured for insertion into a human or animal cavity and a probe base magnetoresistance device configured for remaining outside the cavity. The system and method detect the ferromagnetic object by comparing the electrical signals generated by the probe tip and the probe base magnetoresistance devices in response to the ambient magnetic field without generating a magnetic field to detect the ferromagnetic object.

Abstract: A lock for permanent attachment to a movable freight container cargo door as a replacement for a prior art hasp or a prior art keeper. The lock is configured for permanent attachment to the cargo door using pre-existing hole locations for the prior art hasp or keeper. The lock comprises a straight shackle and a c-shaped lock body and is configured to retain a door handle between the shackle and the back of the c-shaped lock body. The shackle is locked into the lock body using a shackle lock element that engages with a groove in the shackle. The shackle groove is perpendicular to the shaft of the shackle. The shackle lock element is pressed into the groove using by one or more springs in linear direction that is perpendicular to the length of the shackle and perpendicular to the groove, and released from the groove through by a lock module, which could be a lock cylinder or an electronic lock module.

Abstract: A system and method for analyzing an air sample from a human uses a collection module that has a plurality of metal oxide semiconductor sensors that have different resistance responses to different gaseous compounds. A detector circuit reads the output of the sensors as analog signals for both ambient air and the air sample from the human. The ratios of the analog signals from ambient air and from the air sample can be compared to similar information from other health and unhealthy human subjects to determine the health status of the human. In one embodiment the system is used for breath analysis.

Abstract: A locking system and method for a movable freight container door comprises an electronic module and a mechanical lock element. The mechanical lock element comprises a shaft, at least of portion of which is configured to be inserted through an aperture in the electronic module, across a door handle retention region, and into a cavity in the electronic module. The shaft is securely retained in the electronic module by moving a lock mechanism to a locked position. At least one magnetic field sensor in the electronic module is used to read the position of the shaft in the cavity by sensing or not sensing one or more magnets in the shaft. A wireless communication component in the electronic module wirelessly transmits magnetic field sensor information.

Abstract: A freight tracking system uses a tracking device hidden in the taillight of a vehicle and a remote device located somewhere else on the vehicle. The remote device determines the position of the vehicle using information received from global navigation system satellites and communicates this wirelessly to the tracking device using a mesh network. The tracking device comprises a 9-axis IMU (inertial measurement unit) that uses a fusion filter and a calculation involving digital quaternions to determine inertial information. The vehicle position is compared to geographic boundary information to determine if the vehicle might have gone outside of geographic boundaries. If so, a geofencing alarm is triggered. The device has a tampering detector to ensure that the device is not opened. The alarms, vehicle position, and time information can be communicated to an internet-connected database using a cellular wireless device.
