  • Publication number: 20050080754
    Abstract: A communications device for fetching data received from some other device from a receive buffer into a memory managed by software, responding to an occurrence of a receive interrupt or a timer interrupt. A frequent occurrence of the receive interrupt or the timer interrupt leads to smooth establishment of a communications link with the other device, but results in reduction of the communications efficiency unless adopting a CPU higher in throughput or additional hardware. In the communications device, determination is made whether a communications link has been established or not. If established, the data is fetched in response to only the timer interrupt. If not, the data is fetched in response to either the receive interrupt or the timer interrupt. Consequently, the communications efficiency can be successfully improved, and the link can be smoothly established, without depending on CPU or hardware throughput.

  • Patent number: 6714540
    Abstract: A control portion A transmits only a transmission right to a control portion B. The control portion B receives the transmission right sent from the control portion A, obtains transmission-requested data B from a utilization portion B, and then transmits it with the transmission right to the control portion A. The control portion A receives the data B and transmission right transmitted from the control portion B. If the control portion A is receiving a transmission request for data A from the utilization portion A at this time, it first obtains the transmission-requested data A from the utilization portion A and transmits it to the control portion B together with the transmission right. After transmitting the data A, the control portion A transfers the data B received from the control portion B to the utilization portion A.

  • Publication number: 20030120728
    Abstract: A method of making a schedule that enables a user to visit a plurality of places such as entertainment spots and sightseeing spots in optimal order based on waiting time at those places, and a schedule distribution system using the method are provided. At each of those places, an information provider apparatus 30 for detecting waiting time is placed in advance. A server 20 collects waiting time at each information provider apparatus 30 at any time. Upon receipt of a schedule distribution request from a mobile communications terminal 10, the server 20 first obtains a current position of the mobile communications terminal 10. The server 20 then calculates traveling time from the current position of the mobile communications terminal 10 to each place (that is, each information provider apparatus 30). The server then adds the waiting time and the traveling time together for each information provider apparatus 30 to calculate time require for entering the place (information provider apparatus 30).

  • Patent number: 6223261
    Abstract: The present invention relates to communications in which transmit data generated in processes in which a utilization portion performs arbitrary application processing are transmitted to an exterior in accordance with a previously determined protocol in a control portion. A RAM comprises a transmission buffer and a management table for managing a state where each of the transmit data, whose request for transmission has been accepted by the control portion, is transmitted and the location, on the transmission buffer, of the transmit data. The utilization portion outputs, when the transmit data is generated, a request to acquire a data write area to the control portion. Correspondingly, the control portion refers to the management table, to specify a data write area where writing is newly allowed in the transmission buffer and present the specified data write area to the utilization portion. The utilization portion writes the transmit data into the presented data write area.

  • Patent number: 5715519
    Abstract: In radio communication, the invention delivers a transmission signal wave from a transmission station to a plurality of receiving stations whereby the signal wave places the station in communication with the receiving stations using the same carrier passage reciprocally. The transmission station can determine the service condition of the carrier passage on the space in which communication takes place so that generation of the carrier wave which interferes with the station in the midst of communication can be prevented. There is a signal wave transmitter for transmitting specified signal waves from the other station at intervals shorter than the transmission intervals of the response signals. There is a monitor for monitoring whether the interference wave exists in the carrier passage on the space in which the delivery of the waves is about to be performed when an optional station of the radio communication stations begins to deliver the transmission wave or transmit the signal wave.

  • Patent number: 5266093
    Abstract: There is provided a plunger position detector for detecting a linear position of a plunger used for forming a parison over the entire range of moving of the plunger. Since there is correlation between the plunger position and the gob weight, the gob weight can be detected in response to an output signal of this detector and, in accordance with this detection, a gob forming operation is controlled to an optimum state so that the gob weight will become a predetermined weight. Since difference in center positions between a blank mold for forming a parison and the plunger causes variation in the state of movement of the plunger, this difference in the center positions can be detected in response to a plunger position detection signal and, in accordance with this detection, an optimum registering of the center positions can be performed.
