Fixture for shielding a printed circuit board from electromagnetic interference and noise during testing
A shield enclosure includes a housing with a peripheral wall that defines a cavity, and a cover removably coupleable to the housing to at least partially seal the cavity. The cavity is sized to receive a printed circuit board therein. The housing shields the printed circuit board from electromagnetic interference and noise during noise figure testing of a radiofrequency component on the printed circuit board.
Enclosure for testing electronic devices
Various devices and techniques help to reduce the entry of unwanted radio waves into an enclosure and reduce the reflection of radio waves inside the enclosure. Such devices and techniques enable a test environment inside the enclosure that provides high-quality functionality and performance testing.
Attachable portable protective containers
Apparatus for protecting sensitive equipment from impact, dust, dirt, moisture, smoke, and flame has a container that attaches to load bearing equipment used by military, law enforcement and related professions. Apparatus for an attachable protective case capable isolating sensitive equipment from electromagnetic radiation. The apparatus can include an attachment component pivotably associated with the container. A distal end of the attachment component can include a locking feature releasably engageable with a corresponding locking feature disposed on a portion of the container such that the attachment component captures a portion of material of a separate device between the attachment component and the container.
METHOD FOR SHIELDING A PRINTED CIRCUIT BOARD FROM ELECTROMAGNETIC INTERFERENCE AND NOISE DURING TESTING

The cavity is sized to receive a printed circuit board therein. The housing shields the printed circuit board from electromagnetic interference and noise during noise figure testing of a radiofrequency component on the printed circuit board.
SYSTEM AND METHOD FOR DEVICE STATE DETERMINATION
A data processing device includes an internal volume for housing devices and an isolation test system. The isolation test system makes a determination that an electromagnetic interference suppression state of the data processing device is to be determined; in response to the determination: suppresses generation of electromagnetic radiation by the devices; while the generation of the electromagnetic radiation by the devices is suppressed: identifies a quantity of second electromagnetic radiation that propagated through a boundary of the internal volume; makes a second determination, based at least in part on the quantity, that the electromagnetic interference suppression state of the data processing device is an electromagnetic interference suppression compromised state; and initiates performance of an action set to remediate the electromagnetic interference suppression compromised state of the data processing device based on the second determination.
Magnetically shielded room
A magnetically shielded room, that is capable of suppressing positional deviation of a measuring tool in an internal space, has an upper shielding body, a side periphery shielding body, and a lower shielding body, which form a magnetically shielded internal space of the magnetically shielded room. A pedestal has a higher rigidity than the lower shielding body, and is located on an under surface of the lower shielding body. First and second supporting members are located on and stand erect from the pedestal. The first and second supporting members penetrate the lower shielding body and extend into the internal space.

Electromagnetic interference (EMI) evaluation system for image sensors
An apparatus configured to measure electromagnetic radiation coupled from an image sensor integrated circuit (IC) to a nearby cell phone antenna has an image sensor PCB with the image sensor IC on a first side and image sensor decoupling capacitors disposed on a second side, the image sensor PCB disposed within a shielding box. The apparatus also has an image processor PCB with an image processor IC on a first side and at least one image processor decoupling capacitors, the image processor IC electrically coupled to the image sensor IC. The image processor IC is located outside the shielding box, and the at least one image processor decoupling capacitor is within the shielding box. In embodiments, the decoupling capacitors are shielded with separate, additional, metal covers.
Magnetically shielded room
A magnetically shielded room includes an upper shielding body, a side peripheral shielding body and a lower shielding body, all of which define a magnetically shielded inner space. The magnetically shielded inner space is divided into first and second inner spaces by a partition member which is a magnetic shielding body. A door, which is a magnetic shielding body, is provided for commonly closing the first and second inner spaces.
RADIOFREQUENCY ELECTROMAGNETIC RADIATION-SHIELDING SMART-KEY HOLDER AND METHODS THEREOF
A two-piece EMR-shielding smart-key holder is disclosed including a first piece having a cavity within a body sized to hold one or more smart keys, an EMR-shielding layer lining the cavity, and a first piece of a touch fastener incorporated into a second face of the body. A second piece of the smart-key holder includes a second piece of the touch fastener. A method is also disclosed including adhering a second face of the second piece of the smart-key holder to an object's surface leaving a first face of the second piece having the second piece of the touch fastener exposed. The method also includes fastening the first and second pieces of the smart-key holder together by way of complementary touch-fastener features, thereby attaching the first piece to the object's surface shielding the one or more smart keys from at least radiofrequency communications in place on the object's surface.
