An in-circuit test system having means to stimulate the device-under-test at any desired electrical node of the device, means to record the device's response waveform at any node, means to edit the response waveform, and means to use the edited waveform to restimulate the same device in a subsequent in-circuit test.

A device may receive a merchant query including first merchant data associated with a first merchant. The first merchant data may be provided, as input, to a merchant matching model associated with a merchant data structure, the merchant matching model having been trained to determine a measure of confidence that input merchant data corresponds to an existing merchant in the merchant data structure. The device may receive, as output from the merchant matching model, a measure of confidence that the first merchant data corresponds to a second merchant, the second merchant being associated with second merchant data stored in the merchant data structure. The device may also determine, based on the measure of confidence, that the first merchant corresponds to the second merchant. Based on the determination, the device may obtain the second merchant data from the merchant data structure and perform an action based on the second merchant data.

A robotic cleaning device and method of control thereof. The device and method enable multiple cleaning passes within an environment efficiently, cleaning the entire environment more than once, or cleaning the entire environment and then focusing on one or more particularly dirty areas to provide enhanced cleaning by making one or more passes over a dirty area in a dominant and a non-dominant direction. The robotic cleaning device may identify such areas in the course of its cleaning, or it may record such areas previously as being historically dirty and requiring additional attention. The device may vacuum; it may shampoo; it may polish; or it may perform other cleaning operations. Where the device is battery-powered, the device may check its state of charge before performing the enhanced cleaning, and may repeat the enhanced cleaning if the battery or batteries have sufficient charge.

An enhanced distance detection system for an autonomous or semi-autonomous vehicle is described here. The distance detection system includes a distance detector, which may have a limited scope of distance detection, and a directional controller, which allows extending the dimension or scope of the distance detector as the vehicle travels and performs missions. The directional controller can change the detection direction of the distance detector with a motorized gimbal or functionally similar system, and the change in the detection direction can be integrated with the status of and other instructions executed by the vehicle.
