A straw forming machine includes a feeding device, a pressing device, a sticking device, a conveyor device, and a cutting device. The paper material is stretched from the feeding device to the pressing device which curls the paper material. When the paper material is delivered to the sticking device, the two sides of the paper material are pressed by the sticking device to form the paper pipe, and the press roll of the sticking device rolls and sticks the two abutting portions of the paper pipe. Then, the paper pipe is delivered by the conveyor device to the cutting device which cuts the paper pipe to form drinking straws.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). Locations of collection, charging and distribution machines having available charged portable electrical energy storage devices are communicated to or acquired by a mobile device of a user, or displayed on a collection, charging and distribution machine. The locations are indicated on a graphical user interface on a map on a user's mobile device relative to the user's current location. The user may use their mobile device select particular locations on the map to reserve an available portable electrical energy storage device. The system nay also warn the user that the user is near an edge of the pre-determined area having portable electrical energy storage device collection, charging and distribution machines. Reservations may also be made automatically based on information regarding a potential route of a user.

The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.

For the reported resveratrol analogs, the (E)-stilbene core structure is either maintained intact or only slightly modified. We use a different approach and introduced a novel heterocyclic benzothiazolium moiety into the (E)-stilbene core to form a series of novel resveratrol analogs for treating angiogenic- and/or inflammation-related disorders.

Methods for channel scanning are provided. An embodiment of a method for channel scanning comprises scan progress information stored when interrupting a channel scanning process. A carrier RF subsequent to the most recently processed carrier RF is locked onto with reference to the stored scan progress information when resuming the interrupted channel scanning process. Channel information of a program carried by the locked carrier RF is acquired. The acquired channel information of the program is stored in a channel table.

A linear-cavity all-fiber-based ultra short pulse laser system is provided. The all-fiber-based ultra short pulse laser system includes a pulse pump light source, a gain fiber, a first fiber signal pump combining unit, a broadband optical isolator, a fiber saturable absorber, an assistant light source, a second fiber signal pump combining unit, and a light coupling output. A broadband amplified spontaneous emission, emitted by the first fiber signal pump combining unit, which is connected to the pulse pump light source and the gain fiber, passes through the broadband optical isolator. The second fiber signal pump combining unit is connected to the assistant light source and the fiber saturable absorber. An ASE signal actively provides passive mode locking of the cavity, and the light coupling output partially outputs the laser. A dispersion fiber controls the temporal width.

A ring-cavity or linear-cavity all-fiber-based ultra short pulse laser system and method of operating the same are provided. The all-fiber-based ultra short pulse laser system includes a pulse pump light source, a gain fiber, a first fiber signal pump combining unit, a broadband optical isolator, a fiber saturable absorber, an assistant light source, a second fiber signal pump combining unit, and a light coupling output. The first fiber signal pump combining unit is respectively connected to the pulse pump light source and the gain fiber to emit broadband amplified spontaneous emission, then the broadband amplified spontaneous emission passes through the broadband optical isolator. The second fiber signal pump combining unit is respectively connected to the assistant light source and the fiber saturable absorber. An ASE signal actively provides passive mode locking of the cavity, and the light coupling output partially outputs the laser. A dispersion fiber controls the temporal width.

A method includes forming an aluminum alloy structure, performing a first anodizing process to form a first color layer on the aluminum alloy structure, performing a first cutting process to form at least one first working groove in the first color layer and the aluminum alloy structure, performing a second anodizing process to form a second color layer in the first working groove, performing a second cutting process to form at least one second working groove in the first color layer and the aluminum alloy structure, and performing a third anodizing process to form a third color layer in the second working groove. Thus, the aluminum alloy structure is worked by cutting processes and anodizing processes to form an aluminum alloy product so that the aluminum alloy product has multiple color layers.
