Abstract: Systems and methods are provided for exchanging electrode tips, e.g., electrode tips used in resistance spot welding, and disposing of used/unusable electrode tips. Used/unusable electrode tips may be collected, e.g., while within an assembly line. Such used/unusable electrode tips may be routed to a receptacle(s) reside outside the assembly line. Accordingly, disposing or removing of the used/unusable electrode tips can be accomplished without stopping the assembly line, and decreasing any chance for safety events.

Abstract: A method for transferring an electronic device includes steps as follows. A flexible carrier is provided and has a surface with a plurality of electronic devices disposed thereon. A target substrate is provided corresponding to the surface of the flexible carrier. A pin is provided, and a pin end thereof presses on another surface of the flexible carrier without the electronic devices disposed thereon, so that the flexible carrier is deformed, causing at least one of the electronic devices to move toward the target substrate and to be in contact with the target substrate. A beam is provided to transmit at least a portion of the pin and emitted from the pin end to melt a solder. The electronic device is fixed on the target substrate by soldering. The pin is moved to restore the flexible carrier to its original shape, allowing the electronic device fixed by soldering to separate from the carrier.

Abstract: A vehicle can include a first wheel, a second wheel, and a steering system. Either both the first wheel and the second wheel can be front wheels or both the first wheel and the second wheel can be rear wheels. The steering system can be configured to concurrently cause: (1) a steering angle of the first wheel to be at a first angle and (2) a steering angle of the second wheel to be at a second angle. A difference angle can be a difference of the first angle subtracted from the second angle and can be greater than an angle determined to comply with Ackermann steering geometry. Such a difference angle can act to securely brake the vehicle when the vehicle is parked at a location at which a three-dimensional shape of a topological relief of the location can complicate an effort to securely brake the vehicle.

Abstract: Apparatus and associated methods relate to a select frequency phase measurement (SFPM) time of flight (TOF) system including an emitter and a receiver. The emitter may generate a modulated emitted signal by at least one frequency. The emitted signal may, for example, be a pulsed light signal. The receiver may generate a signal in response to receiving a reflection of the emitted signal off a target object. An ADC element may digitize a signal generated by the receiving element, and a reference signal generated by a monitored signal of the modulated emitted signal. A processing element may generate a phase signal using single frequency analysis of the digitized signals. A distance measurement signal may be generated as a function of the phase signal. Various embodiments may, for example, advantageously enable sub-millisecond sensor response times using commodity processing elements.
