Abstract: A headset for audio play, comprising one or more sensor circuit and a control module. The control module comprises a secondary processor circuit and a primary processor circuit. The sensor circuit generates sensor data according to structural deformations of the headset. The secondary processor circuit receives the sensor data and calculates measured values related to the structural deformations of the headset. The primary processor circuit coupled to the secondary processor circuit controls an audio play operation in the headset, and enters a sleep mode when the audio play operation is not required. The secondary processor circuit determines a usage status of the headset according to the measured value and one or more threshold value. The secondary processor circuit wakes the primary processor circuit according to the usage status, and adaptively adjusts at least one threshold value according to the usage status.

Abstract: A sonic ranging method for a mobile phone and a wireless earphone. Firstly, the mobile phone performs an acoustic response test on the wireless earphone. The mobile phone generates a first audio sequence at a first time slot. The wireless earphone recognizes the first audio sequence to generate a second audio sequence. When the mobile phone recognizes the second audio sequence, the mobile phone estimates a length of elapsed time according to the time difference between a current time slot and the first time slot. When the mobile phone obtains the length of elapsed time, a distance between the wireless earphone and the mobile phone may be determined according to a delay compensation parameter and the length of elapsed time. Various potential applications can be implemented based on the invention without the needs for additional hardware circuits in the mobile phone.

Abstract: Example inter-process communication methods and apparatus are descried. One example method includes writing, based on a calling convention, communication information into a register group of a first execution entity of a sending process. First data of target data is written into a stack memory of the first execution entity. The communication information includes a first value indicating a data amount of the first data, and the target data is data to be sent by the sending process to a first receiving process. Information in the register group of the first execution entity is replicated to a context of the first execution entity. The first data from the stack memory of the first execution entity is replicated to a stack memory of a second execution entity of the first receiving process based on the first value in the context of the first execution entity and the address of the stack memory.

Abstract: An energy absorbing device for subway vehicle includes a movable anti-climber, a fixed anti-climber, an energy absorbing honeycomb, at least one collapse tube, two sliding-groove assemblies and two guide sliding rails. As the first stage energy absorbing unit of the total structure, the energy absorbing honeycomb directly bears the collision impact transferred from the movable anti-climber. Through the deformation of the energy absorbing honeycomb itself under pressure, the collision kinetic energy transfers into internal energy of deformation and heat, thus realizing the energy absorbing buffering. As the second stage energy absorbing buffering unit, the at least one collapse tube further absorbs the collision energy, thus further buffering and protecting the underframe of the vehicle body, as well as ensuring that the impact energy performs a multistage and serial operation according to a predetermined direction and sequence, thereby ensuring the reliability of operation of the energy absorbing device.

Abstract: The provision of dental restorations can be improved by generating a cold atmospheric plasma inside the mouth of the patient and then applying that cold atmospheric plasma onto a dental restoration site. The dental restoration site can be composed of either or both of dentin and enamel. Further, the provision of dental restorations can also be improved by introducing a dental adhesive onto a dental restoration site and treating it with a cold atmospheric plasma.

Abstract: A surface-enhanced Raman spectroscopy substrate device, including a base substrate, a single or multiple layered nanostructure that contains metals, and a plasma coating. The nanostructure metal is selected from the group including silver, gold, platinum, copper, titanium, chromium, and combinations thereof. The plasma coating has a thickness of 1-200 nm and may locate on the nanostructure layer or on the base substrate. The plasma coating can precisely control the surface characteristics, including surface energy, hydrophilicity, and contact angle, of the SERS device and may then help to regulate the SERS substrate with well defined and uniform water/oil contact angle with small standard deviation. The water contact angle of the SERS substrate may range from 20 to 140 degrees.

Abstract: An atmospheric cold plasma brush was used to treat the surfaces of polymers. The surface properties of plasma-treated polymers were compared to those of the corresponding untreated polymers by static water contact angle measurements. Surface treatment usually resulted in a decrease in the static water contact angle, indicating that the treatment resulted in a higher surface energy and surface wettability compared to the untreated polymer.

Abstract: An apparatus with a narrow slit chamber generates plasma having non-equilibrium characteristics and a brush-like shape at a temperature near room temperature and at a pressure of about one atmosphere. Plasma gas enters the narrow slit chamber. An external power source provides power to electrodes near the exit that excite the plasma gas and produce a plasma jet having a brush-like shape that exits the chamber. The apparatus operates with low power consumption, and the temperature of the plasma is low. Glow-to-arc transitions are prevented using a ballast resistor and appropriate plasma gases with the narrow slit chamber design. The brush-like shaped plasma extends beyond the exit of the chamber, and possesses the reactive features of low-pressure or non-equilibrium plasmas. The plasma brush apparatus can be used for plasma treatment, plasma cleaning, plasma deposition, plasma sterilization, and plasma decontamination of chemical and biological warfare agents.
