Abstract: Disclosed herein is a device and method for correlating core sample zones with an actual subterranean depth. The disclosed device has a pair of independent distance measuring devices operably in communication with a core sample apparatus where a first distance measuring device measures the length of a core sample entering a core sampling tube and a second distance measuring device measures a drive depth of the core sampling tube entering into the ground. A processing unit is provided for correlating the two distances so as to allow a determination as to the actual depth below ground from where a given zone of the core sample is extracted.

Abstract: An exercise apparatus that is configured to provide execution of a plurality of exercises wherein the exercise apparatus includes a bar member having movable segments operably coupled therewith. The exercise apparatus includes a bar member wherein the bar member includes a core section having a first end and a second end. The core section has telescopically secured thereto a pair of inner extendible segments and a pair of outer extendible segments. The outer extendible segments are configured to comprise the majority of the total weight of the exercise apparatus. The exercise apparatus is configured with a central processing unit, a motion sensor and a transceiver that are operable to facilitate a communicable coupling with a remote computing device. The exercise apparatus is configured to have a plurality of accessory elements secured thereto such as but not limited to a pull up accessory and a push up accessory.

Abstract: A compass system includes a processing circuit configured to use the deviations for each of the plurality of headings to calculate a plurality of compass deviation coefficients representative of different types of noise sources. At least one compass deviation coefficient is determined based on a database of geographic zone error factors stored in the memory device and based on a position of the compass. The processing circuit is configured to update the database of geographic zone error factors using an internet connection. The processing circuit is configured to store the deviation coefficients in memory and to at least one of calibrate the compass and adjust an output from the compass using the compass deviation coefficients.

Abstract: An emergency stopping system for track mounted movable targets used divergent cables to stop a target trolley which has not been otherwise stopped before coming to the end of a track. As the trolley passes over the diverging cables, the cables are forced together, causing the trolley to dissipate kinetic energy.

Abstract: An in-vehicle compass system and method that is calibrated based on a magnetic field model and/or a deviation analysis based on a location signal received from a positioning system.

Abstract: A reusable ballistic door for use in the training of individuals such as police officers and military personnel. The door may be formed to have different weak spots, requiring different techniques to enter the door. The door may be quickly and inexpensively rebuilt for subsequent training. A reusable training door may also be used inside of a shoot house to provide realistic training scenarios.
