Abstract: An audio switching device includes a housing, a first user interface, and a controller within the housing and in electronic communication with the first user interface. The controller is configured to connect a first audio source to the audio switching device, connect a first listening device to the audio switching device, such that an output from the first audio source is received at the first listening device, receive a first input from the first user interface, disconnect the first listening device in response to receiving the first input, and connect a second audio listening device to the audio switching device, such that an output from the first audio source is received at the second listening device.

Abstract: A small area real-time air pollution assessment system includes a databank, a model generation module, an input module and an analysis module. In a small area real-time air pollution assessment method, the model generation module generates a model by analyzing historical tested persons' historical body characteristics data and historical air data in a plurality of monitored areas, which storing in a databank; inputs from an input module to the model a plurality of current tested persons' body characteristics data in a to-be-monitored area to generate air data corresponding to the current tested persons; selects a specified value of each of those air data and converts the specified values into air quality index values; selects a specific value of those air quality index values; and compares the specific value with an air quality health assessment table to generate assessment results. Thus, relatively accurate small area air pollution assessment results can obtainable.

Abstract: A method for preparing IGZO particles and a method for preparing an IGZO thin film by using the IGZO particles are disclosed. The method for preparing the IGZO particles comprises the following steps: (A) providing a solution of metal acid salts, which contains a zinc salt, an indium salt, and a gallium salt; (B) mixing the solution of the metal acid salts with a basic solution to obtain an oxide precursor; and (C) heating the oxide precursor to obtain IGZO particles.

Abstract: An auto-bill-dispensing machine is provided. The auto-bill-dispensing machine comprises bill receiver having a plurality of security hooks positioned axially between two positioning plates formed on the two sides of the upper chassis of the bill receiver, and the security hooks are against within a plurality of blocking grooves of the lower chassis to block the bill passage. When the bill enters into the bill passage and being held against on the security hooks, the security hooks of the bill receiver will be out of the blocking groove of the lower chassis to let the bill pass through, and after the bill passes the security hooks, the security device will return to the original position to make the security hooks support within the blocking groove of the lower chassis to prevent the bill being pulled back by a string, a tape, a steel wire or a glued metallic plate.
