Disclosed are a method for controlling a terminal device, a terminal device and an electronic device. The method comprises: acquiring a first input; determining, in the locked state, a first instruction of the first instruction set corresponding to the first input, the first instruction being an unlocking instruction; controlling a switching from the locked state to the unlocked state according to the unlocking instruction; determining, in the unlocked state, a second instruction of the second instruction set corresponding to the first input; and responding to the second instruction. With the present invention, user operations are simplified, and intelligence of the terminal device is improved.
摘要:
A concrete structure member strengthened with prestressed FRP elements includes a concrete structure body and a prestressed FRP element arranged on the former. An epoxy resin overlay surrounding the prestressed FRP element is provided to wrap it up, and a polymer concrete supplemental layer is provided outside the epoxy resin overlay. The concrete structure member can uniformly and effectively transfer the stress from the prestressed FRP element.
摘要:
Strains of xylose utilizing Zymomonas with improved xylose utilization and ethanol production during fermentation in stress conditions were obtained using an adaptation method. The adaptation involved continuously growing xylose utilizing Zymomonas in media containing high sugars, acetic acid, ammonia, and ethanol.
摘要:
This invention discloses a novel compound with the structure of formula I, or pharmaceutically acceptable salts or solvates thereof. In addition, the invention further discloses a method for preparing the compound, a pharmaceutical composition containing the compound, and use thereof in the preparation of a hypoglycemic medicament.
摘要:
An L-arabinose utilizing yeast strain is provided for the production of ethanol by introducing and expressing bacterial araA, araB and araD genes. L-arabinose transporters are also introduced into the yeast to enhance the uptake of arabinose. The yeast carries additional genomic mutations enabling it to consume L-arabinose, even as the only carbon source, and to produce ethanol. A yeast strain engineered to metabolize arabinose through a novel pathway is also disclosed. Methods of producing ethanol include utilizing these modified yeast strains.
摘要:
A compound preparation contains alpha-lipoic acid and nimodipine at a ratio from 5:1 to 40:1. The above-mentioned compound preparation can be used for the prevention and treatment of noise-induced hearing impairment. This compound preparation not only increases the efficacy but decreases the dosage of nimodipine, reduces the side effects and improves the patient compliance.
摘要:
A power-on reset circuit includes a first circuit and a second circuit. The first circuit include a first NMOS transistor having a gate controlled by a low voltage supply VDD_L, a resistor connected between the source of the first NMOS transistor and a voltage supply VSS that is lower than VDD_L, and one or more diodes serially connected between a high voltage supply VDD_H and the drain of the first NMOS transistor. The second circuit includes a first PMOS transistor having a source connected to VDD_L, a second PMOS transistor having a source connected to the drain of first PMOS transistor, a second NMOS transistor connected between the drain of the second PMOS transistor and VSS, and an inverter configured to output a signal in response to the power on of the high voltage supply VDD_H and the low voltage supply VDD_L.
摘要:
Methods and apparatus for detecting on-screen media sources are disclosed. An example method includes monitoring a region of interest of a video signal for a first image, comparing the first image to a stored image, and confirming the media device change when the stored image differs from the first image and is associated with a secondary criterion.
摘要:
Copolyesters containing secondary hydroxyl groups are useful polyols for manufacturing polyurethanes. These can be prepared by reacting a secondary hydroxyl-containing fatty acid or ester thereof with an initiator containing hydroxyl and/or primary or secondary amino groups. A copolyester of particular interest includes a poly(ethylene oxide) segment derived from a poly(ethylene oxide) initiator.
