Abstract: A flip-chip light-emitting device includes a transparent substrate, an epitaxial structure, a transparent dielectric layer, a plurality of first contact electrodes, multiple second contact electrodes, a metallic reflection layer, a first insulating layer, and an electrode pad region. The epitaxial structure is formed on the transparent substrate, and includes a first type semiconductor layer, an active layer, and a second type semiconductor layer. The first and second contact electrodes are embedded in the transparent dielectric layer, and respectively connected to the first and second type semiconductor layers. The second and first contact electrodes are arranged in an array. The second contact electrodes are disposed in a region perpendicularly below the first pad and are distributed along a circular ring that is concentric with one of the first contact electrodes. A light emitting module includes a circuit board, and the flip-chip light emitting device is mounted on the circuit board.

Abstract: The light-emitting device includes a substrate, a light-emitting chip unit formed on the substrate and including multiple chips, an isolation groove extending in a first direction and separating two adjacent ones of the chips, and a bridging structure. The isolation groove is defined by a bottom and two sidewalls and has a first groove section and a second groove section arranged in the first direction. The first groove section has a width in a width direction perpendicular to the first direction that is greater than a width of the second groove section in the width direction. At the first groove section, one of the sidewalls has a curved portion. The bridging structure is formed on the bottom and the sidewalls, covers the curved portion, and electrically connects the two adjacent ones of the chips.

Abstract: This disclosure provides systems, methods, and apparatus related to a porous transport layer for use in an electrolyzer. In one aspect, a method includes providing a porous transport layer this is to be a component in an electrolyzer cell. Features are created in a first surface of the porous transport layer. The features serve to increase a surface area of the first surface of the porous transport layer.

Abstract: Disclosed herein are systems and methods for a continuous analyte monitoring system for measuring a concentration of a first analyte and concentration of a second analyte in a host. One such system utilizes a working electrode and a reference electrode to measure glucose concentration and oxygen concentration in bodily fluid of a host. The system includes a sensor control circuit that applies a first bias condition to the sensor to measure a first signal generated by the sensor indicative of a concentration of the first analyte. The sensor control circuit also applies a second bias condition to the sensor to measure a second signal generated by the sensor indicative of a concentration of a second analyte at the host.

Abstract: An anti-slip fluorescent electronic energy-saving lamp comprises a fluorescent tube or bulb and a lamp cabinet within which the electronic parts are installed. The outer shell of the lamp cabinet is of a surface of revolution, on which an anti-slip ring is mounted. The anti-slip ring is made of anti-slip materials and the ring sectional plane of the anti-slip ring is in parallel with the circular sectional plane of the outer shell of the lamp cabinet. Thanks to the anti-slip ring mounted outside the outer shell of the lamp cabinet, the fluorescent electronic energy-saving lamp of the present invention is easy to grasp and will not be easily to fall to the ground and break into pieces in installation and usage. Since the anti-slip ring is made of rubber or plastic, it can be made into various colors, which is helpful for identification and decoration.
