摘要:
An automatic power control system provides a control signal that regulates the output power of at least one laser diode. Coarse adjustment of the control signal is provided by a first means, preferably a digital variable resistor, while fine adjustment and compensation is provided by a second means, preferably by a digital-to-analog converter that receives an input signal proportional to a sensed control system parameter. The control system includes an operational amplifier having a first input coupled to sense output power, and a second input coupled to a DAC to provide finer resolution control. Memory can store system parameter or system parameter variations that can be coupled to the DAC and/or variable resistor to enhance system stability over ambient variations.

Systems and methods for planning and executing a search route by a mobile sensor platform for detecting reflection are disclosed. The search route of the mobile sensor platform is based on the angle of a radiation source relative to the ground in a search area. While executing the search route, a sensor on the mobile sensor platform is configured to detect the reflection of radiation from an object in the search area.

Systems and methods for updating a navigation system are provided. In one implementation, a system includes: a navigation system configured to provide a navigational solution; at least one memory device configured to store a terrain object database, the terrain object database storing information that describes a terrain; a user interface configured to display a terrain model and receive position adjustments from a user; and a processing unit configured to generate displayable information for displaying the terrain model using the information stored on the at least one memory device and the navigational solution, and calculate corrections to the navigational solution from the position adjustments and transmit the corrections to the navigation system.

A system for applying wallboard finishing compound comprising a container with an opening and tray sized and shaped to fit within the opening. The tray has a first chamber for receiving the wallboard finishing compound and a second chamber having a grip formed therein. The tray is further shaped to receive a joint knife and a roll of tape. A lid is sized and shaped to cover the opening and enclose the tray in the container.

Systems and methods for detecting a present location of a target from a moving platform are provided. One system includes a movement module for estimating the present location of the target, a prediction module for estimating future locations of the target, and a first processor. The first processor is configured to receive present location estimates, receive future location estimates, store the future location estimates to create a first future location estimate, and determine the present location of the target based on the present location estimate and/or the first future location estimate. One method includes receiving an estimate of the present location of the moving platform, receiving an estimate of a future location of the moving platform, and determining the present location of the target based on the estimate of the present location and/or the estimate of the future location.
