Abstract: The present invention discloses a container equipment for enclosed transportation and heterotopic and aerobic stabilization of reserved garbage, which includes a container body and a functional lining provided on an inner wall of the container body, wherein the functional lining is provided with a circulating air low-temperature evaporation system, a water distribution and drainage system and a heating and insulating system; the circulating air low-temperature evaporation system includes an air inlet manifold, an air distribution perforated pipe, a base plate water discharge and air distribution groove and a top plate water distribution and air guide groove, an air extraction perforated pipe, a fan, an air outlet pipe and a quicklime dehydration and deodorization system; the water distribution and drainage system includes a percolate feeding pipe, a fiber capillary water distribution pipe, the top plate water distribution and air guide groove, a side drain, a main drain and a percolate discharge pipe; the hea

Abstract: Embodiments of the present invention provide an IPTV VOD method, apparatus, and system. The method includes: sending the VOD request to IPTV media entertainment management middleware (IPTV-MEM); sending the fee deduction request to a charging apparatus through the SMG; receiving, from the SMG a fee deduction response sent by the charging apparatus in response to the fee deduction request; and if fee deduction succeeds, notifying the IPTV-MEM of pushing a VOD media steam to a target Set Top Box (STB) according to the VOD request. The payment modes for IPTV VOD are diversified and the flexibility of payment for IPTV VOD is enhanced.

Abstract: Wireless access to the internet for the pre-paid customer includes when wireless user terminal logs on the internet through wireless communication network, the user account and password information is sent to the wireless communication network, and the user account, password and the information of the pre-paid money are preserved in the wireless communication network. The wireless communication network performs authentication on the wireless user terminal, and if the wireless user terminal passes the authentication, band-width is allocated for the wireless user terminal. If not, the connection to the wireless user terminal is refused. The terminal logs on and surfs the internet (S04). While receiving the log off request information from the terminal, the charge (S05) is calculated, and the money is deducted from said pre-paid sum, and then the access (S06) ends.

Abstract: The flow rate of a fluid can be measured using an ultrasonic flow meter according to the present invention with a higher measuring accuracy and a lower cost. The feature of the invention consists in an ultrasonic flow meter comprising a measurement tube for flowing a fluid to be subjected to measurement, a first oscillator fitted to the outer circumference of the measurement tube, a second oscillator fitted to the outer circumference of the measurement tube at a predetermined interval along the flow of the fluid from the first oscillator and an acoustic filter fitted to the measurement tube for cutting high frequency range of the oscillating wave propagating through the oscillating tube, in which the flow rate of a fluid is measured based on a time difference between a time required when the ultrasonic wave from the upstream oscillator reaches the downstream oscillator and another time required when the ultrasonic wave from the downstream oscillator reaches the upstream oscillator.
