摘要:
Re-distribution servers are installed at the branch points of a network for distributing streaming data, and route costs between two re-distribution servers are collected. Then, a distribution route tree from a source to a plurality of clients is automatically generated based on the cost information.
摘要:
A system of the present invention is structured based on a connection between an information distributing unit that processes distributed contents information and a client unit of a user via a network such that they can communicate with each other. The contents information selected based on profile information of the user is transmitted from the information distributing unit to the client unit. The system makes the user input evaluation information relating to the evaluation of the transmitted contents information. The contents information to be distributed to the user is changed based on the input evaluation information.

In an information distribution control system, a sync control server adds a time stamp to the stream information JS capable of being reproduced in real time and adds the sync time information to the storage-type information JT, so that the stream information JS and the storage-type information JT are reproduced in temporal synchronism with each other based on the time stamp and the sync time information in a plurality of clients.

A method of delivering and playing content includes delivering, through first-group channels, an entirety of content at a content bit rate with a time difference between each delivery commencement, delivering, through one or more second-group channels, only a start portion of the content at two or more times the content bit rate, selecting, from the first-group channels and the one or more second-group channels, a channel through which the start portion of the content is received earliest after a view request, followed by receiving and playing the start portion, and selecting, after receiving the start portion through the selected channel that is one of the one or more second-group channels, one of the first-group channels through which the remainder of the content is received for a first time after a start of the reception of the start portion, followed by receiving and playing the remainder of the content.

A vehicle brake control device generates rear wheel braking torque by an electric motor by pressing a friction member against a rotating member rotating together with the rear wheel, reduces rear wheel braking torque by controlling the electric motor based on a target energization amount calculated from a slip state quantity of the rear wheel, and rapidly stops electric motor rotation motion based on an adjusted target energization amount calculated from the target energization amount and a slip state quantity of a front wheel.

A hydraulic brake system including: (a) a first hydraulic-pressure generating device including a manual hydraulic pressure source; (b) a second hydraulic-pressure generating device including a power hydraulic pressure source; (c) a manual-operation-associated brake line including a communicating device that is to be brought into communication with the manual hydraulic pressure source and brake cylinder or cylinders of the plurality of hydraulic brakes; (d) an output hydraulic-pressure control device and a flow restraining device disposed in parallel with each other between the manual-operation-associated brake line and the second hydraulic-pressure generating device; and (e) a power hydraulic pressure source control device for activating the power hydraulic pressure source such that the hydraulic pressure is supplied to the manual-operation-associated brake line via the flow restraining device, when the output hydraulic-pressure control device cannot control the hydraulic pressure outputted by the second hydraulic-pressure generating device.
摘要:
A hydraulic brake system includes: a hydraulic pressure source provided for a vehicle, and including a hydraulic-pressure generating device and a reservoir; a plurality of hydraulic brakes provided for respective wheels of the vehicle, and configured to restrain rotations of the respective wheels; and a control valve device including at least one hydraulic-pressure control valve group disposed between the hydraulic-pressure generating device and at least one of brake cylinders of the hydraulic brakes and/or between the reservoir and the at least one of the brake cylinders. Each of the at least one hydraulic-pressure control valve group includes (a) at least one ON/OFF control valve and (b) at least one linear control valve that are disposed in parallel with each other.

A brake system includes: (a) a first brake device including a first actuator and a first brake that utilizes an output of the first actuator; (b) a second brake device including a second actuator and a second brake that utilizes an output of the second actuator; (c) a regenerative-electric-energy obtaining device configured to obtain a regenerative electric energy that is returned to a power source device; and (d) an actuator control device configured to reduce a total consumed electric energy, by controlling the first actuator and/or the second actuator in a manner that maintains a state in which a required braking force is satisfied by a braking force of the first brake and/or a braking force of the second brake, such that the total consumed electric energy is made smaller when a regenerative electric energy is small, than when the regenerative electric energy is large.
摘要:
A stroke sensor abnormality determining apparatus includes a stroke sensor for detecting a stroke of a brake pedal by detecting an electric signal that varies in response to the stroke of the brake pedal, a deceleration calculating unit for calculating a total target value, which is correlated with a target deceleration of a vehicle, based on at least the stroke, and an abnormality determining unit for determining whether or not an abnormality of the stroke sensor occurs, based on the electric signal detected by the stroke sensor, the abnormality determining unit being configured so that a signal indicating the abnormality of the stroke sensor can be outputted when the abnormality is determined to have occurred in the stroke sensor.
摘要:
A liquid propellant tank for storing a liquid propellant A and supplying vapor produced by evaporation of part of the liquid propellant A to an external location comprises a tank body for storing the liquid propellant A, and a plurality of holder plates arranged inside the tank body, around an axis L of the tank body. The holder plates cause the liquid propellant A to adhere to them by surface tension, thereby establishing, inside the tank body, a liquid propellant holding area LA in which the liquid propellant A is held and a gas accumulation area GA in which vapor produced by evaporation of part of the liquid propellant A accumulates. The tank body has a propellant inlet open into the liquid propellant holding area LA and a gas outlet open into the gas accumulation area GA.
