An antenna device and an antenna switch circuit are provided. The antenna device comprises a first antenna, an antenna detection circuit, a switch control circuit, and a controller. The first antenna is configured to transmit an RF signal. The antenna detection circuit comprises an inductor configured to detect a second antenna. The switch control circuit is coupled to the antenna detection circuit and configured to generate a first control signal indicative of the presence of the second antenna upon the detection thereof. The controller is coupled to the first antenna, the antenna detection circuit and the switch control circuit, and configured to receive the first control signal and connect to the second antenna when the first control signal indicates the presence of the second antenna.

Antenna apparatus and antenna switch circuit

A meter apparatus, a metering network, and a metering method thereof are provided. The meter apparatus includes a pulse generator, an optical sensor, a spinning disc, and a magnetic sensor. The pulse generator is configured to generate a number of pulses proportional to an amount of a consumed resource. The optical sensor is configured to detect the number of pulses to generate a first signal, and transmit the first signal to a meter reader. The spinning disc is configured to produce an amount of rotation proportional to the amount of the consumed resource. The magnetic sensor is configured to detect the amount of the rotation to generate a second signal, and transmit the second signal to the meter reader.

Meter apparatus, metering network, and metering method thereof

A signal transmission interface includes: a USB audio format encoding unit adapted to be coupled to a digital broadcast receiving end, for converting a digital audio signal that originates from the digital broadcast receiving end into a USB audio signal; a USB hub coupled to the USB audio format encoding unit and adapted to be coupled to a host end, for transmitting the USB audio signal to the host end and receiving a USB control signal that originates from the host end; and a USB/serial transmission bus bridge unit coupled to the USB hub and adapted to be coupled to the digital broadcast receiving end, for converting the USB control signal that is transmitted from the USB hub into a serial transmission bus control signal, and transmitting the serial transmission bus control signal to the digital broadcast receiving end.
