  • Patent number: 11945665
    Abstract: Systems and methods are disclosed for automated lateral transfer and elevation of sortation shuttles. An example system may include a track having a first portion arranged in a first direction, a shuttle configured to move along the track, and a shuttle carriage system configured to move in a second direction transverse to the first direction, where the shuttle is configured to move from the track to the shuttle carriage system. The shuttle carriage system may include a first frame configured to support the shuttle, a first electromagnet configured to propel the first frame, and a second electromagnet coupled to the first frame, the second electromagnet configured to propel the shuttle off the first frame.

  • Patent number: 11883851
    Abstract: Systems, methods, and apparatuses are disclosed for automated securing and releasing of items on shuttles. In one embodiment, an example item sortation system may include a shuttle having a conveyor, a first gate portion having a second width that is about half a first width of the conveyor, a second gate portion having the second width, an optional third gate portion having the second width, and an optional fourth gate portion having the second width, wherein the third gate portion and the fourth gate portion are disposed at a second side of the conveyor. The first gate portion, the second gate portion, the third gate portion, and the fourth gate portion may be configured to: (i) secure the at least one item on the conveyor during transport, and (ii) guide the at least one item along the conveyor when the item is unloaded.

  • Patent number: 10923379
    Abstract: An insulator-type substrate is positioned on a support surface of a substrate support structure in exposure to a plasma. An initial clamping voltage is applied to an electrode within the substrate support structure to rapidly accumulate electrical charge on the support surface to hold the substrate. A backside cooling gas is flowed to a region between the substrate and the support surface, and a leak rate of the backside cooling gas is monitored. A steady clamping voltage is applied to the electrode, and the steady clamping voltage is adjusted in a step-wise manner to maintain the monitored leak rate of the backside cooling gas at just less than a maximum allowable leak rate. Or, a pulsed clamping voltage is applied to the electrode, and the pulsed clamping voltage is adjusted to maintain the monitored leak rate of the backside cooling gas at just less than the maximum allowable leak rate.

  • Publication number: 20200073210
    Abstract: The present invention is a method using a simple, light, collapsible device comprises a convex mirror with positioning mechanisms, attached in front of the rear camera of a mobile device within the field of view (FOV) of the camera, to re-direct the view of the foreground of the user to the camera, while the device is held in the “walking while texting” position of device held in half-extended upper extremities and eyes on the screen. These images are continuously captured wide-angle frontal views, and using existing feature of the operating system of the device, with or without software manipulation, become upright views of the immediate horizon on the screen, to aid the “walking while texting” and similar user navigate around obstacles and dangers while walking forward. This view can be displayed on a split screen, or used as a background of the screen output of any software.

  • Patent number: 9738889
    Abstract: A syringe device having a plunger beneath which is disposed a rupturable capsule containing a nucleic acid wash buffer and a rupturing mechanism for rupturing the capsule, wherein the capsule, syringe, plunger, and rupturing mechanism are so configured as to first apply pneumatic pressure to force a nucleic acid solution through a membrane and to thereafter rupture the capsule and force a first volume of the wash buffer through the membrane.

  • Publication number: 20070205280
    Abstract: A method and system for collecting, storing, and processing automatic identification code information includes receiving automatic identification code information and parsing it based on stored definitions for automatic identification codes and/or automatic identification code standards. Various data configurations may be used to store definitions and to facilitate parsing of raw automatic identification code data. For example, a first component may be used for generally defining one or more automatic identification code standards and a second component may be used for detailed information regarding code definitions, such as information relating to code segments. In addition, the system may facilitate further processing of parsed automatic identification code information, such as for cycle counting or parts movement of inventory.

  • Publication number: 20070024888
    Abstract: A system and methods enable the protection of valuable media from theft or other improper access by people who might use the media for dishonest, illegitimate, or criminal purposes. An evaluation of a print job results in a determination regarding whether the print job is suspected of being an attempt to improperly access blank, valuable media. A suspect print job can be stopped or canceled, and a message can be sent which notifies an appropriate administrator of the possibility that an illegitimate attempt has been made to acquire blank, valuable media.
