Abstract: A detector for detecting the removal and/or insertion of a weapon out of and/or into a holster. The detector may transmit a message each time the weapon is removed from the holster. A recording system may receive the message and determine whether or not it will begin recording the data it captures. A detector may detect the change in a magnitude of an inductance and/or an impedance of a circuit to detect insertion and removal of the weapon into and out of the holster. The holster is configured to couple to the detector to position the detector to detect insertion and removal of the weapon. An adhesive tape may couple a detector to a holster.

Abstract: A layered tactical information system and a method of sharing tactical information between multiple layers are provided. The method performed by a processor of each layer of the multiple layers includes searching for relevant data available to the processor of the layer in response to at least one of a layer request from the processor of another layer of the multiple layers and a directive received by a processor of a first layer of the multiple layers. The directive specifies an end state, one or more target types, a time window, a geographic location area, and a first layer requirement of at least one layer requirement to be resolved by the processor of the first layer. The method performed by the processor further includes evaluating whether a layer requirement of the at least one layer requirement for the layer is satisfied based on at least one of (a) any found relevant data that was found by the search and (b) layer data obtained from at least one of the other layers.
