Abstract: An energy storage and release apparatus and a method for energy storage and release are disclosed. The energy storage and release apparatus includes a first compression unit, a first heat exchange unit, a gas storage unit, and a turbine unit. The first heat exchange unit is directly or indirectly connected between the gas storage unit and the first compression unit. A first gas enters the first compression unit via a first inlet; sequentially passes through the first compression unit, the first heat exchange unit, the gas storage unit, and the turbine unit; and then is discharged. A first temperature of the first gas before entering the first heat exchange unit is higher than a second temperature of the first gas after passing through the first heat exchange unit, and a first heat energy is provided by a temperature difference between the first temperature and the second temperature.

Abstract: Disclosed are methods for imaging lumen-forming structures such as blood vessels using near-infrared fluorescence in the NIR-II region of 1000-1700 nm. The fluorescence is created by excitation of solubilized nano-structures that are delivered to the structures, such as carbon nanotubes, quantum dots or organic molecular fluorophores attached to hydrophilic polymers. These nanostructures fluoresce in the NIR-II region when illuminated through the skin and tissues. Fine anatomical vessel resolution down to ?30 ?m and high temporal resolution up to 5-10 frames per second is obtained for small-vessel imaging with up to 1 cm penetration depth in mouse hind limb, which compares favorably to tomographic imaging modalities such as CT and MRI with much higher spatial and temporal resolution, and compares favorably to scanning microscopic imaging techniques with much deeper penetration.

Abstract: A hinge is mounted between a cover and a base of an electronic device and has a supporting bracket, a rotating bracket, a mounting bracket and a pintle. The supporting bracket is connected to the base, and the rotating bracket is connected to the cover. The mounting bracket is attached to the supporting bracket and has a positioning wing and two sleeves. The pintle is attached to the rotating bracket, is mounted through the mounting bracket and has a flat wall. The flat wall of the pintle selectively abuts against the positioning wing of the mounting bracket to hold the cover at a desired position. The abrasion between the sleeves and the pintle balances torque.

Abstract: A hinge has a pintle, a spacer assembly, a stationary bracket and a rotating bracket. The pintle is mounted through the spacer assembly and is connected to the stationary and rotating brackets. The spacer assembly has multiple spacers stacked with each other. Each spacer has a ring segment and a bearing segment. The ring segment is mounted around the pintle. The bearing segment has an absorbing space to absorb the stress acting on the ring segment. Therefore, the spacer sustains less stress to prevent breakage easily and a lifespan of the spacer is extended. Therefore, the hinge has a longer lifespan.

Abstract: A torque-adjustable hinge is mounted between a display panel and a base of a portable device and has a stationary bracket, a rotating bracket, a pintle, a torsional spring and an adjusting element. The stationary bracket is attached to the base. The rotating bracket is attached to the display panel. The pintle is attached to the rotating bracket and is mounted through the torsional spring. The torsional spring is attached to the stationary bracket and abuts against the adjusting element. By changing the height that the adjusting element protrudes above a receiving tag of the stationary bracket, the torsional spring is selectively tighter or looser wound around the pintle. Therefore, the torque generated by the hinge is adjusted without replacing any element.
