The hand controller can apply to mounting desks of different thicknesses and improve the universality of the hand controller.

A male connector (100) includes a contact pad substrate (101) and a connector shell (102). The contact pad substrate (101) includes a linear array of contact pads (103a, 103b, 103c, 103d) that are adapted for aligning with corresponding contacts (103′a, 103′b, 103′c, 103′d) of a contact-bearing tongue (104′) of a corresponding female connector (100′) that conforms to a USB Series A receptacle contact pad pitch specification. The two outermost contact pads (103a, 103d) of the linear array are electrically connected together. The connector shell (102) is formed from an insulating material and comprises a tubular portion (102a) for insertion into the corresponding female connector (100′), and a handling portion (102b) for handling during insertion.

A portable data accessing device and more particularly the use of multi-port interfaces on a data accessing device disclosed. The multi-port data accessing device includes an inner body, one or a plurality of moving-caps, one or a plurality of grips, a pump-action and one or a plurality of locking/releasing mechanisms.

According to examples, an apparatus may include a housing having a bay, the bay having a surface opening. The apparatus may also include a connector attached to the housing and a first jaw movably positioned in the bay, the first jaw having a threaded through hole. The apparatus may further have a threaded fastener extending through the surface opening and threadably engaging the threaded through hole, in which rotation of the threaded fastener is to cause the first jaw to move linearly in the bay to removably lock the connector to a port.

A docking station may include a first communication port to couple the docking station to a target computing device, a rota table plate, and a fixed plate. The docking station may be rotatably coupled to the target computing device about the first communication port via the rota table plate and the fixed plate.

In accordance with example embodiments, an automated ground fault interrupter includes means for resetting itself following detection of a ground fault. In accordance with example embodiments, when a ground fault is detected, a relay switch opens and breaks the conducting path between an AC input and a plug for connecting devices for a set amount of time after which the relay switch is closed again, restoring the conducting path between the plug and the AC input. Following restoration of the conducting path, the relay switch is opened again if a ground fault is detected. In accordance with example embodiments, the automated ground fault interrupter automatically tests itself at predetermined intervals. In accordance with example embodiments, the ground fault interrupter is automatically reset following the automatic test.
