Abstract: A crime scene is recorded as to the locations of key evidence such as a knife in relation to a victim's body. The criminalist places a stand next to each piece of evidence. An onboard RTK/GNSS receiver displays the latitude, longitude and altitude of each marker. Additional data such as case number, classification of evidence, number assigned to evidence, weather and comments can be entered into the RTK/GNSS device remotely or by a keyboard attached to the marker. A photo is taken of each marker screen. A UAV is launched over the field of evidence. A local transmission of the RTK/GNSS data can be sent to and stored in a portable electronic device. That device can send the data to a UAV and/or to a central computer. The central computer can use the recorded coordinates to visually recreate the crime scene to a jury years later with accurate representation of relational data among all the items of evidence.

Abstract: A circuit board and component manipulation device includes a housing having a circuit board clamp located thereon for positioning a circuit board on the housing. Hot gas for soldering or desoldering operations can be directed to components on the circuit board from one or the other of both an upper gas duct and a lower gas duct, both of which are fed gas from a blower. Each of the ducts include an individual heater located therein so as to control heat input to the gas passing through the ducts. The upper duct terminates in a discharge head which includes a nozzle attached thereto. The nozzle includes an appropriate opening so as to receive a circuit component. The opening is surrounded by a skirt with the gas ducts then positioned outwardly from the skirt. By positioning the component within the skirt, the component is isolated from hot gas utilized for soldering or desoldering of the connectors of the component to an appropriate circuit board.
