Novel tools and techniques are provided for implementing an isolation chamber, and more particularly for implementing an EMF shielded isolation chamber. In various embodiments, an isolation tank might include a shell comprising an upper cover and a lower tank portion having one or more sidewalls connected to a floor. The lower tank portion might be configured to hold liquid and the lower tank portion and the upper cover together might define an interior chamber configured to receive a user. The isolation tank might further include a conductive shield associated with at least a portion of the shell and configured to shield at least a portion of the interior chamber from external electromagnetic fields. In various additional embodiments, the isolation tank might include a shield ground for electrically grounding the shield and/or a liquid ground for electrically grounding the liquid.

A grounding structure for a vehicle provided with a floor portion formed of a resin material includes a sheet-shaped wiring sheet including a conductive material for electrical connection between an electric power supply and an electronic component and a sheet-shaped conductive portion electrically connected to a grounding potential. The conductive portion includes a part disposed to overlap a surface of the wiring sheet on an inner portion side of the vehicle.

A wiring structure according to the present disclosure includes a shield tube, a metal wire, and a plate-like member. The shield tube covers a wiring. The metal wire fixes the shield tube. The metal wire fixes the shield tube to the plate-like member by pressing the shield tube against the plate-like member. The plate-like member is connected to a grounding path in a manner that enables electric conduction. The shield tube is connected to the grounding path via the plate-like member in a manner that enables electric conduction.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about ?20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.

A system for limiting or diminishing current to unpowered Serializer/Deserializer (SerDes) circuitry is provided. The system comprises receiver input termination circuitry and a cold spare circuitry. The receiver input circuitry comprises a termination resistor and an N-type metal oxide silicon field effect transistor (MOSFET). The cold spare circuitry comprises a first MOSFET and a second MOSFET. When the system is powered on, an input current flows to the receiver input termination circuit to be discharged by the N-type MOSFET which is electrically connected to a ground. When the system is powered off, the input current flows to the cold spare circuitry to discharge the input current. Discharging electrons between the first MOSFET and the second MOSFET depends on the polarity of an accumulated voltage.

A robot system comprising: a robot having an attaching/detaching mechanism; a controller; and a hand stand on which hands are put and includes a ground circuit for electrically grounding the hands, wherein a first electrode to which detection voltage is applied is fixed to the robot, each of the hands has a reference position used when the hand is attached to the attaching/detaching mechanism, and is provided with a second electrode so that distance from the reference position to the second electrode differs for each hand, a detecting unit for detecting current in the ground circuit is provided, the controller includes: a storage that stores the types of the hands and those corresponding positions of the second electrodes, and a hand identifying unit that identifies whether the hand is a selected hand based on the current when the first electrode is moved to a position of the second electrode.

A camera module comprises: a first body including a lens; a second body coupled to the first body; and a printed circuit board arranged in the first body, wherein the first body includes a first ground portion protruding downward, and the second body includes a second ground portion protruding upward to contact the first ground portion.

A coated chamber component comprises a chamber component and a coating deposited on a surface of the chamber component, the coating comprising an electrically-dissipative material. The electrically-dissipative material is to provide a dissipative path from the coating to a ground. The coating is uniform, conformal, and has a thickness ranging from about 10 nm to about 900 nm.

A field device having a non-metallic housing and electrical components accommodated in a Faraday cage includes an electrically conductive pin to ground the cage. For this purpose, the housing includes a bushing into which the pin can be inserted along an axis. The housing and the cup are arranged relative to each other such that the receiving region of the cup for the end of the pin is aligned with the bushing along the insertion axis. The field device includes an electrically conductive spring that resiliently encloses the end of the pin in the receiving region radially with respect to the insertion axis such that the pin is electrically contacted with the cup. A particular advantage of this design is that the pin cannot tilt during insertion despite any component tolerances of the cup or of the housing.

A printed circuit board includes a printed board, a first integrated circuit chip, a connector, and a capacitor. The printed board includes a first ground pattern and a second ground pattern directly opposed to the first ground pattern. The second ground pattern is electrically connected with a chassis or connector ground wiring. The capacitor is connected to the first ground pattern and the second ground pattern and disposed on a straight line that defines the shortest distance between the first ground terminal and the second ground pattern.
