  • Patent number: 11932497
    Abstract: A method of inverting workpieces in a mass production process includes: advancing an end effector in electronic synchronization with advancement of a carrier to synchronize arrival of the carrier at a stop position with arrival of the end effector at an unloading position, in which the end effector is in alignment with a workpiece held by the carrier for engaging the workpiece; while the end effector is in engagement with the workpiece, retracting the end effector away from the carrier to unload the workpiece from the carrier and advancing the end effector back toward the carrier to load the workpiece back into the carrier; and rotating the end effector relative to the carrier to invert the workpiece in electronic synchronization with the retracting and advancing of the end effector for loading the workpiece back into the carrier when inverted.

  • Patent number: 11476641
    Abstract: A window material for protecting near infrared light emitting lasers and or detectors is coated with a conductive coating that reduces the reflection at the wavelengths and angles of incidence of interest. The conductive coating allows the window to be heated by applying a bias across connected electrodes to remove or prevent the condensation of liquid water and the buildup of ice. The conductive material in the coating has some optical absorption in the hear infrared region of about 800 to 1600 nm, which in combination with multiple intervening dielectric layers also allows the transmission of 90% of the light while obtaining a resistance of less than about 30 Ohms-square. The coating reduces reflection loses from the window, without decreasing transmission by more that about 10%.

  • Patent number: 10914789
    Abstract: A battery system monitor includes cell measurement circuits (CMCs) that each measure a voltage at or current through a pair of terminals of a respective associated battery module from among a plurality of plurality of battery modules in a battery system. Wireless communication transceivers (WCTs), each associated with a different CMC, transmit voltage or current measurement information of the associated CMC across a wireless communication link. A controller receives the voltage or current measurement information from the wireless communication transceivers for monitoring the state of operation of the battery system. Battery system monitoring is improved through synchronization of clocks in different CMCs or WCTs to enable synchronous sampling of multiple battery modules, through systems for determining relative positions of battery modules in a series coupling of battery modules between terminals of the battery system, and through improvements to the reliability of wireless communication.

  • Patent number: 9660456
    Abstract: Technique for providing power to a powered device (PD) over a cable having first and second sets of twisted pairs, such as signal pairs and spare pairs. Power Sourcing Equipment (PSE) circuitry is coupled via a first switch to the second set, e.g. to the spare pairs. A switch control circuit turns the first switch off to enable the PSE circuitry to perform a prescribed operation in connection with the PD over only the first set, e.g. over the signal pairs, and turns the first switch on to enable the PSE circuitry to perform the prescribed operation in connection with the PD over the first and second sets.

  • Publication number: 20160261255
    Abstract: A threshold detection circuit may sense when current between a power supply and a load reaches a current threshold level. The threshold detection circuit may include a transistor in series with the load; a feedback circuit that causes the voltage drop across the transistor to be constant while the transistor is conducting current between the power supply and the load; a constant current source that delivers a constant current into the load; and a comparator that indicates when the voltage drop across the transistor falls below a voltage threshold level.
