To reduce noise which leaks to the outside in an ultrasonic diagnostic apparatus. An internal AC wiring unit 34 is composed of internal AC wiring which is installed on the input side of a power source circuit, and a shield case 38 which accommodates it. The internal AC wiring includes an inlet, a plurality of connectors, a relay substrate, and a plurality of internal AC cables. The internal AC wiring is protected from radiation noise which is generated in a casing 22 by the shield case 38. Thereby, the noise which leaks to the outside via an external AC cable is reduced.

A method of manufacturing an electronic device housing includes obtaining a monolithic body of RF transparent material and plating a surface of the monolithic body with a nanograin coating to increase the structural rigidity of the monolithic body. A portion of the nanograin coating is thereafter removed to create an RF window.

In one more alternative embodiment of the present invention, the lid and each compartment is provided with a locking and unlocking system. In one or more alternative embodiment of the present invention, the device is provided with a user interface that informs the user on the device's status (e.g. powered on, empty, filled compartments, audio jamming status etc.).

A housing device for isolating electromagnetic interference emitting devices includes a structural frame for housing the electromagnetic interference emitting devices. The housing device further includes a non-structural electromagnetic interference isolating enclosure. The non-structural electromagnetic interference isolating enclosure is for encapsulating the structural frame. The non-structural electromagnetic interference isolating enclosure includes an access portion that enables the structural frame to be accessed. The access portion includes a vent.

This proximity sensor includes: a cylindrical housing having an opening at one end in the axial direction; a detection part housed at the other end of the housing and detecting the presence or absence of a detection target contactlessly; a substrate housed in the housing and mounted with a control circuit for controlling the detection part; a detection part shield preventing external noise from entering the detection part and including a first face part adhered to the front surface on the other side of the detection part, and a side face part configured from multiple side pieces connected to the outer periphery of the first face part and bent from the first face part to cover the side surface of the detection part; and a resin provided around the detection part and the detection part shield.

A laminate curtain can suppress electromagnetic radiation leakage from an electronic appliance, as well as assist in managing cables interconnected to the electronic appliance. More specifically, a laminate curtain can include a conductive elastomer panel that absorbs spurious electromagnetic radiation generated by the electronic appliance, a conductive adhesive film disposed along one side of the conductive elastomer panel, and a conductive support frame affixed to the conductive adhesive film. The laminate curtain can be installed within a mounting frame, which secures the laminate curtain to the electronic appliance. Electromagnetic radiation that is absorbed by the conductive elastomer panel can travel to the electronic appliance via the conductive adhesive film, the conductive support frame, and the mounting frame. Thus, the conductive elastomer panel can be used to form a ground plane that catches and shunts the spurious electromagnetic radiation to the electronic appliance, which is grounded.

A technique for selectively configuring a case of a handheld device to shield an antenna from receiving or transmitting wireless signals is disclosed. The technique includes moving a blocking element on the case between a first position and a second position. The blocking element is a physical structure that is rotatable, slidable, or removable to switch between the first position and the second position. In response to moving the blocking element to the first position, the blocking element blocks wireless signals received or transmitted by the antenna of the handheld device. In response to moving the blocking element to the second position, wireless signals can be received or transmitted through the case by the antenna.
