Abstract: A method, system and computer program for determining the orientation of an apparatus relative to a vehicle in which the apparatus is installed is disclosed. Acceleration data of the apparatus along three mutually orthogonal axes at a first time interval is recorded (100). Speed and heading data of the apparatus at a second time interval is recorded (100). A first vector which corresponds to the direction of gravity is determined (102) using the acceleration data. One or more periods of acceleration in a substantially straight line are identified (104) using the speed and heading data. Acceleration data corresponding to the identified one or more periods of acceleration in a substantially straight line is selected (106). A second vector which is orthogonal to the first vector and which corresponds to a forward direction of the vehicle is determined (110) using the selected acceleration data.

Abstract: A device for monitoring an underground utility vault environment includes environmental sensors including at least one primary sensor and at least one secondary sensor, a processor for receiving output data from the sensors and for compiling an alarm data packet, and a communications module for transmitting data from the device. The processor determines whether an alarm condition is present based on the output data from the primary sensor(s) and, when an alarm condition is present, compiles an alarm data packet comprising data derived from the primary sensor(s) and secondary sensor(s), and causes the communications module to transmit the alarm data packet. The primary sensor(s) may include a carbon monoxide sensor. The device may include a waterproof housing, a plurality of internal sensors including a gas sensor, and a port for allowing gas exchange between the environment outside the housing and the gas sensor and preventing water ingress.

Abstract: A collision is detected using an accelerometer attached to a vehicle. Acceleration data is received (100) from the accelerometer at discrete intervals. The acceleration data is summed (106) over a time period to produce an accumulated acceleration. Whether a collision has occurred is determined based at least in part on a comparison (108) of at least one of the accumulated acceleration and a function of the accumulated acceleration to a threshold.

Abstract: A system and method for detecting and recording events related to the quality of service experienced by a wireless device in a wireless network. In one example, these events may be detected and recorded by the wireless device, without support from the network. Performance monitoring tests may be initiated by the wireless device at the direction of a management server, independent of the network in which the device may be operating. The wireless device may store the results of these tests and report the results to the management server.
