摘要： Methods and system for testing a voice-enabled device. A signal generator generates a carrier signal having a variable resonant frequency, and a frequency mixer mixes an audible voice command signal with the carrier signal to generate an inaudible amplitude-modulated test signal. An antenna transmits the amplitude-modulated test signal at a variable attack angle to a voice-enabled device. The resonant frequency of the carrier signal and/or the attack angle of the transmitted amplitude-modulated signal are varied and at least one of a sensitive frequency and a sensitive attack angle of the voice-enabled device is identified.

摘要： A dismantling device including a main body, a driving member and an insert is provided. The main body includes a through hole. The driving member is rotatably assembled to the main body. The insert is rotatably disposed in the assembling hole of the first portion. Whereby, an object to be dismantled can be placed in the hole to abut against the insert. A tool is used to drive the driving member to rotate. A protrusion of the driving member is inserted into the through hole for holding the object so that the object can be rotated to be dismantled. As a result, the object can be hold stably by the insert so that the dismantling device can be used for dismantling objects in different sizes.

摘要： A wrench includes a transmitting device and a shell. The transmitting device comprises a rotor, a first working member, a second working member, a first linking member and a second linking member. The first linking member is disposed between the first working member and the rotor. The shell has a containing room for the linking device to be disposed therein. The shell comprises a middle section. The first end of the middle section extends upwardly to connect with the first section. The second end of the middle section extends downwardly to connect with the second section. Thus, the wrench has two stair portions of different horizontal level. And Users can hold the wrench more stably. Because the wrench uses the rotor and two linking members to drive the first working member and the second working member rotating, a total size of the wrench can be kept as smaller as possible.

摘要： A method for treating highly concentrated resin-desorption liquid generated from wastewater deep purification, including channeling the highly concentrated desorption liquid generated from anion exchange resin treatment through a nanofiltration membrane, the liquid being separated into nanofiltration permeate that can be reused as the desorption agent and highly concentrated nanofiltration retentate; adding a coagulating agent to the highly concentrated nanofiltration retentate to generate coagulation-precipitation; subjecting the supernatant formed after the coagulation-precipitation process to Fenton oxidation or ozone oxidation; after the reaction, adding to the liquid an alkali solution for further coagulation-precipitation; then channeling the liquid so treated back to the biochemical system of biochemical effluent treatment for further biodegradation is provided. The recycled treatment of the highly concentrated desorption liquid consequently reduces the treatment cost and prevents secondary pollution by realizing innocuous treatment and reclamation of resin-desorption liquid as well as reduction of its total volume.
