A mobile device includes a substrate, a ground element, and a radiation branch. The ground element includes a ground branch, wherein an edge of the ground element has a notch extending into the interior of the ground element so as to form a slot region, and the ground branch partially surrounds the slot region. The radiation branch is substantially inside the slot region, and is coupled to the ground branch of the ground element. The ground branch and the radiation branch form an antenna structure.

A mobile device includes a ground plane, a grounding branch, and a feeding element. The grounding branch is coupled to the ground plane, wherein a slot is formed between the ground plane and the grounding branch. The feeding element extends across the slot. The feeding element is coupled between the grounding branch and a signal source. An antenna structure is formed by the feeding element and the grounding branch.

An antenna module is adapted for disposing in an electronic apparatus that includes first and second housing members and that is operable in a tablet mode, in which the first and second housing members are disposed in a manner that the first housing member overlaps the second housing member. The antenna module includes: a first antenna element to be disposed in the first housing member; and a second antenna element to be disposed in the second housing member, and corresponding substantially in position and proximate to the first antenna element for electromagnetic coupling therewith when the electronic apparatus is operated in the tablet mode.

A portable electronic device includes a metallic casing, a circuit board, a feeding line, and a grounding line. The metallic casing confines an accommodating space, and is formed with a slot that is in spatial communication with the accommodating space and that is defined by a slot-defining wall. The circuit board is disposed in the accommodating space, and is provided with feeding and grounding ports. The feeding line serves to couple electrically the feeding port to the slot-defining wall. The grounding line serves to couple electrically the grounding port to the slot-defining wall.

An antenna includes loop and single-pole antenna members, and an inductor. The single-pole antenna member is spaced apart from the loop antenna member. The inductor has a first inductor terminal coupled to the loop antenna member, and a second inductor terminal coupled to the single pole antenna member. A desired resonance frequency of the antenna can be achieved by simply adjusting the inductance of the inductor.

Microfluidic devices and methods including porous polymer monoliths are described. Polymerization techniques may be used to generate porous polymer monoliths having pores defined by a liquid component of a fluid mixture. The fluid mixture may contain iniferters and the resulting porous polymer monolith may include surfaces terminated with iniferter species. Capture molecules may then be grafted to the monolith pores.

Embodiments of fluid distribution manifolds, cartridges, and microfluidic systems are described herein. Fluid distribution manifolds may include an insert member and a manifold base and may define a substantially closed channel within the manifold when the insert member is press-fit into the base. Cartridges described herein may allow for simultaneous electrical and fluidic interconnection with an electrical multiplex board and may be held in place using magnetic attraction.

A multi-band antenna includes a feed-in section, a loop conductor, a first conductor arm, a second conductor arm, and a third conductor arm. The feed-in section includes a feed-in point for feeding of signals. The loop conductor extends from the feed-in section and has a grounding point disposed adjacent to the feed-in point. The first conductor arm is configured to resonate in a first frequency band and extends from the feed-in section. The second conductor arm is configured to resonate in a second frequency band and extends from the feed-in section. The third conductor arm is configured to resonate in a third frequency band and extends from the feed-in section. At least one of the loop conductor, the first conductor arm, the second conductor arm, and the third conductor arm is bent so as to be disposed in different planes.

A long term evolution antenna includes a dielectric substrate, a primary antenna structure disposed on a surface of the dielectric substrate, and a metal plate disposed on the dielectric substrate and connected to the primary antenna structure. The primary antenna structure includes a trunk section, and a first conductor arm, a second conductor arm and a loop conductor which all extend from the trunk section. The metal plate is connected to the first conductor arm and the second conductor arm so as to form a first radiator section for resonation in a first frequency band with the first conductor arm and a second radiator section for resonation in a second frequency band with the second conductor arm. The loop conductor extends from the trunk section to form a loop for resonation in a third frequency band.

The present invention provides a device and methods of use thereof in concentrating a species of interest and/or controlling liquid flow in a device. The methods, inter-alia, make use of a device comprising microchannels, which are linked to nanochannels, whereby induction of an electric field in the nanochannel results in ion depletion in the linkage region between the microchannel and nanochannel, and a space charge layer is formed within the microchannel, which provides an energy barrier for said species of interest which enables its concentration in a region in the microchannel.
