An imaging mass spectrometer comprising an energy source adapted to substantially simultaneously provide energy to multiple spots on a sample to produce ions from the sample by a desorption process; and an analyzer adapted to detect the arrival time and spot origin of ions resulting from said desorption process. After receiving a specification, a voice application is configured based on the specification. Another embodiment includes a first pump for the evacuation of an engine oil reservoir and a second pump for the selective evacuation of transmission and hydraulic fluid reservoirs. When the user plays the files afterward, he can obtain audio, video, operational-activity, and running-status information simultaneously. , in a manner virtually transparent to the user. The invention may also be used to optimize the routing of data calls to maintain optimal modem performance.
