A swivel mount assembly for rotational mounting of an electronic device to a mounting structure includes a rotatable body inserted, in part, into an opening in the mounting structure and rotatable about an axis extending through the mounting structure opening. A plate part above the mounting structure has an opening that opens into the mounting structure opening. A sidewall is joined at one end to the plate part and has a side aperture formed therein. A roller is disposed in the opening in the plate part and directs a cable extending through the opening in the mounting structure to further pass through the side aperture. A hold/release mechanism, disposed above the plate part, holds the cable and prevents its movement when the hold/release mechanism is in a first setting, and releases the cable and permits its movement when the hold/release mechanism is in a second setting.

A stand having a base, an arm attached to the base, an electrical connector, and an adjustable mounting head attached to the arm. The adjustable mounting head includes a plurality of keepers actuated by a button, wherein the plurality of keepers are each configured to engage a respective one of a plurality of receivers on a case for an electronic device such that the case is removably attachable to the adjustable mounting head for holding the case and an installed electronic device on the stand in a preferred orientation. The mounting head includes electrical contacts electrically connected to the electrical connector of the stand and configured to contact an electrical interface of the case for providing the electrical power from the electrical connector of the stand to the installed electronic device through the electrical contacts of the mounting head and through the case.

A polymer holder for a biosignal processing device, wherein a wall of the polymer holder forms a pocket, and the wall follows an outer contour of the biosignal processing device. The polymer holder has a first aperture for inserting the biosignal processing device into the pocket and removing the biosignal processing device from the pocket. The polymer holder includes an electrically conductive contact structure, which is in a wired electric contact with electrodes that receive the at least one biosignal, at a rear section opposite to the first aperture, and the electrically conductive contact structure is at least partly attached inside the wall. The electrically conductive contact structure is electrically connected with a counterpart of the biosignal processing device in response to an insert of the biosignal processing device in the pocket.

A surge protector with an anti-off structure includes a pluggable module and a base. The base includes external terminal connection parts on both sides. The top of the external terminal connection part of the base is provided with a sliding limit device. Both sides of the pluggable module are provided with limit protruding blocks. The sliding limit device includes a hole cover, and the hole cover is slidably connected to the top of the external terminal connection part. When the pluggable module is completely inserted, a part of the hole cover protrudes into the pluggable module installation slot and is clamped with a fixing limit device of the pluggable module to limit the pluggable module from being detached from the base. When the pluggable module is removed, the hole cover is moved toward both sides, such that the hole cover is separated from the fixing limit device.
