Abstract: In an example, a laser system receives an externally generated single command. The single command may be selected from a set of commands usable to control a laser diode driver of the laser system. The laser system may determine whether to select a group of one or more commands from the set of commands. In response to a determination to select the group of the one or more commands from the set of commands, the laser diode driver may be controlled using the one or more commands of the group.

Abstract: A laser driver subsystem includes a pump diode driver, operable to generate light pulses to energize a laser, and a lithium polymer battery. The pump diode driver includes a pump diode and a switched-mode power conversion circuit at an input connected to an output of the battery and at an output connected to an anode of the pump diode. The switched-mode power conversion circuit is configured to convert an electrical voltage from a first level at the output of the battery to a second lower voltage level at the pump diode anode so as to provide the pump diode with an electrical current that enables the pump diode to generate the light pulses to operate the laser while only a fraction of that current needs to be supplied by the battery.

Abstract: A plurality of capacitors is subjected to a test cycle of charging, soaking and discharging. While in the soaking cycle, a plurality of measurements of current is obtained. The data is used to train a predictive function. Then, a test capacitor is charged and soaked for a shorter period than the plurality of capacitors. The current through the test capacitor is measured more than once during its soak period, and the measured current values are applied to the predictive function to predict whether the current through the test capacitor at the end of the soak time period would be higher than a predetermined value, thus indicating failure of a leakage test by test capacitor.

Abstract: An electrical test system for providing a power source to each of a plurality of electrical components under electrical test includes a grouped circuitry module. The grouped circuitry module includes a plurality of individually-programmable power sources, each coupled to an output channel, a controller configured to program each of the power sources to a respective stimulus output value and to read a measured value at each corresponding output channel and random access, non-volatile, memory for storing information and for providing read/write capability for the controller. A host computer is in communication with the controller for running a self test program that sequentially programs each of the power sources to its respective stimulus output value and reads the measured value at each corresponding output channel using the controller to determine if the tested complete subsystem is operating properly.

Abstract: An apparatus and method for measuring the leakage current of capacitive components. A switch that grounds a terminal of a component being tested is closed while the component is charged to a desired test voltage. When this charging is complete, the switch opens so that the diode terminal is at the same potential as the input amplifier's virtual ground. An accurate and fast measurement of the leakage current of the component can be measured.

The test device can be selected from a group consisting of a volt meter, a current meter, a precision voltage/current source, a calibration resistor, and a calibration capacitor. The control program can perform at least one test function through the plate. The test function can be selected from a group consisting of alignment verification, voltage/current source verification, insulation resistance (IR) leakage measurement verification, part-present contact check verification, capacitance and dissipation (CD) measurement verification, IR/CD compensation, and IR/CD calibration.
