  • Patent number: 9798935
    Abstract: A method is described for determining a body parameter of a person outside a vehicle. The method may include capturing a first set of data of the person by a first data capturing device of the vehicle, the captured first set of data representative of a first body posture of the person, capturing a second set of data of the person by a second data capturing device of the vehicle, the captured second set of data representative of a second body posture of the person different from the first body posture, and using the first and second sets of data as input for estimation of the body parameter of the person. Use of a data capturing device of a vehicle is also described, and optionally a distance measurement system of the vehicle, for determining a body parameter of a person according to the method.

  • Patent number: 6292834
    Abstract: An efficient transmission protocol for transmitting multimedia streams from a server to a client computer over a diverse computer network including local area networks (LANs) and wide area networks (WANs) such as the internet. The client computer includes a playout buffer, and the transmission rate is dynamically matched to the available bandwidth capacity of the network connection between the server and the client computer. If a playtime of the playout buffer, which is one measure of the number of data packets currently in the playout buffer, drops below a dynamically computed Decrease_Bandwidth (DEC_BW) threshold, then the transmission rate is decreased by sending a DEC_BW message to the server. Conversely, if the number of packets remaining in the playout buffer rises above a dynamically computed Upper Increase_Bandwidth (INC_BW) threshold and does not drop below a Lower INC_BW threshold for at least an INC_BW wait period, then the transmission rate is incremented.
