Abstract: Devices and methods are provided for separation of particles of a first selected electrophoretic mobility or isoelectric point from a fluid comprising particles of at least one other selected electrophoretic mobility or isoelectric point. The devices comprise a microchannel; electrodes to either side of the microchannel for applying a selected voltage to produce an electrical field across the microchannel orthogonal to the length of the microchannel; and outlets in said microchannel placed to receive outlet portions of the fluid containing enhanced concentrations of each type of particle. The devices may be used for particle detection, quantification, separation, mixing, dilution and concentration; to release, separate and detect interior particles of cells or organisms, and to separate particles such as proteins and microorganisms from biological fluids such as blood; or to separate and detect airborne contaminants such as bacterial warfare agents from air.

Abstract: A mounting apparatus is provided for a data storage device defining a plurality of mounting holes. The mounting apparatus includes a bracket for accommodating the data storage device, a locking latch, and an action member. The bracket includes a side plate. The locking latch is elastically attached to the side plate of the bracket, for securing the data storage device in the bracket. A plurality of securing members is formed on the locking latch, corresponding to the mounting holes. The action member is attached to the side plate of the bracket. The action member includes a pair of elastic arms each having a fixed end and a free end. A pair of blocking members is respectively formed at the free ends, for securing the locking latch to the side plate of the bracket.

Abstract: A mounting apparatus is provided for a data storage device defining a mounting hole. The mounting apparatus includes a bracket for accommodating the data storage device and a locking latch. The bracket includes a side plate forming a cantilever thereon. A receiving portion is formed at a free end of the cantilever. The locking latch is pivotally attached to the side plate. The locking latch has an initial position parallel to the side plate. A projecting portion extends from the locking member, and is received by the receiving portion of the cantilever. A securing member is formed on the locking latch. When the locking latch is pivoted away from the side plate, the cantilever is distorted to store a potential elastic energy for urging the locking latch to move back to the initial position, thereby the securing member engaging into the mounting hole of the data storage device.
