The present disclosure is a full-duplex wireless voice broadcasting apparatus. The apparatus is capable of channel-changing. Full-duplex (two-way) voice communication is achieved by using at least one receiving device and an emitting device. The receiving device has good mobility to be used as an emergent caller to the emitting device. The present disclosure has advantages in interference resistance, energy saving, short-distance emergent calling, and calling for help.

A system for measuring polar substances includes a measurement module, a transfer module, a display module and a store module. The measurement module includes a measurement unit and a transmitter. The measurement unit measures the polar substances and produces a data-related signal. The transmitter transmits the data-related signal. The transfer module includes a receiver and a transmitter. The receiver receives the data-related signal. The transmitter of the transfer module receives the data-related signal from the receiver and transmits the data-related signal. The display module receives the data-related signal from the transmitter of the transfer module and shows the data-related signal. The store module receives the data-related signal from the transmitter of the transfer module and stores the data-related signal.

A parking information sensing device is disclosed. Each parking space in a parking lot is disposed with a parking information sensing device, detecting whether a car on the parking space. By means of a driving control circuit, the sensing device drives a light emitting unit to emit a light and a reflecting element of the parking space is on a pathway of the light. Light is reflected by the reflecting element and then passes light sensing unit that detects the reflected light and generates a first sensing signal sent to the driving control circuit. Thus the driving control circuit judges if there is no vehicle on the parking space. On the other hand, it judges if there is a car on the parking space according to another sensing signal. The sensing device further includes a first transmitting/receiving unit that forms a wireless mesh network among parking information sensing devices.

A die-level prober testing an unpackaged liquid crystal on silicon (LCOS) display panel includes a tray and a probe card. The unpackaged LCOS display panel has at least a first contact pad and a second contact pad. Additionally, the tray includes at least a recession for situating the unpackaged LCOS display panel, and a conductive connecting structure electrically contacting the first contact pad. The probe card is utilized to electrically contact the connecting structure and the second contact pad for testing the unpackaged LCOS display panel.
