  • Patent number: 10141706
    Abstract: Laser diode drivers include switching power supplies situated proximate one or more laser diode arrays so as to provide laser diode drive currents at frequencies of 200 kHz or more. The switching power supplies are generally buck/boost supplies that can provide well regulated outputs even when regulating remote power received from a power supply via a cables having inductances in the hundreds of nH. Multiple laser diode arrays can be driven with independently selectable powers. A drive current for a particular laser array can be controlled so as to reduce voltage drop at voltage control elements such as FETs, leading to increased efficiency, increased product life and decreased sense element failure.

  • Patent number: 10076313
    Abstract: A method of scanning for an object using an adaptive scheduler starts with an electronic circuit (EC) receiving information associated with the object. A task list is then generated by the EC that includes at least one task action based on the information associated with the object. The at least one task action includes a beam firing required for the object to be scanned. The EC may signal based on the task list to a beamer to generate and send a signal to a probe unit to perform the beam firing. A receiver may receive and process a data signal from the probe unit and send the processed data signals to the EC. The EC may then analyze the processed data signal to determine if the object is identified using the processed data signal. Other embodiments are also described.

  • Patent number: 10037477
    Abstract: Described embodiments detect changes in a scene over time using first and second images of the scene. A non-coherent intensity change detector detects large-scale changes between the first image and the second image and generates a large-scale change value for pairs of corresponding pixel locations in the first and second images. If the large-scale change value for a given pair of pixel locations reaches a threshold, a coherent change detector is used to detect small-scale changes between the first and second images. A small-scale change value is generated for the given pairs of pixel locations in the images. A composite change value is generated by combining the large-scale change value and the small-scale change value for each pixel pair. The change thresholds are used to determine whether a change in the scene has occurred over the time period.
