Abstract: An apparatus comprising: a connector for providing an electrical interface, the connector comprising an opening configured to receive a suitable member; at least one conductive contact located at least partially within the connector and configured to operate as a switch such that when the connector is in an unplugged to partially plugged state the at least one conductive contact is grounded and when the connector is in a partially plugged to a fully plugged state the at least one conductive contact is coupled to an electrical terminal channel interfacing an electrical signal between the connector and the member.

Abstract: An apparatus including a housing defining an interior cavity having a length, a width and a depth, at least one lateral constraint configured to constrain the width of the interior cavity when the apparatus is in a first configuration, and at least one longitudinal constraint configured to constrain the length of the interior cavity when the apparatus is in the first configuration, wherein, when the apparatus is in the first configuration, the cavity is configured for a first card, wherein, when the apparatus is in a second configuration, the interior cavity is configured for a second card, larger than the first card, and wherein insertion of the second card into the interior cavity causes depth-wise switching of the apparatus from the first configuration to the second configuration including retraction of at least one of the at least one lateral constraint and the at least one longitudinal constraint.

Abstract: The invention provides a circuit board connector and a connecting method for the circuit board. The circuit board connector includes an insulation housing, having opposed left and right side walls and a bottom wall arranged between the left and right side walls, the left and right side walls and bottom wall forming an accommodating space accommodating a circuit board; terminals arranged on the bottom wall of the insulation housing, the terminals having contact portions within the accommodating space; runners arranged in parallel at the left and right side walls of the insulation housing; and a sliding cover body, with the two ends of the sliding cover body connected to the runners and sliding along the runners. Reliable connection of the circuit board may be realized with no need of a gasket or a film, and without need of an extra space.

Abstract: The present invention is a photocatalysis water purifying device that provides an excellent purging water quality feature. The outermost part of the device is equipped with a light-pervious cover; the inner part of the device has an ultraviolet tube. Furthermore, a photocatalysis membrane is clothed outside the light-pervious cover. Due to the direct application of the photocatalysis membrane on the ultra violet tube and the utilization of the silica gel to seal up the opening for water-resistance purposes, this device can be put in the water alone with the tube and thereby effectively provides the antibacterial and germ-eliminating functions based on the stimulation between violate-rays and photocatalysis. Moreover, the device can be used together with an air-supplier to assist the chemical reaction of photocatalysis.
