  • Data communication system, data transmitting device, data transmitting method, data receiving device, and data receiving method
    Publication number: 20100091801
    Abstract: A probe transmitting section (216) in a packet receiving terminal (210) sends a probe packet to a second radio channel (320) at fixed intervals. A probe analyzing section (117) in a packet sending terminal (110) detects a burst loss on the basis of a state of reception of the probe packet. When a burst loss detection is detected, a predictive retransmission control section (118) predicts that a data packet transmitted during the period of the detected burst loss among data packets sent from a priority processing transmission buffer (115) to a first radio channel (310) is a data packet lost on a receiving side, reads the data packet from a retransmission buffer (114), and then sends the data packet to the priority processing transmission buffer (115). A real-time property can be ensured while a packet loss is overcome in a radio environment.

  • Collapsible lens barrel
    Patent number: 7689110
    Abstract: A cam pin (16) and a demating prevention pin (35) that are provided in a driving frame (15) and have an identical shape are allowed to mate with a cam groove (18) and a demating prevention groove (36) that are provided in a cam frame (17), respectively. A first protrusion (37) is provided on at least one side in an optical axis direction of a portion of the demating prevention groove (36) with which the demating prevention pin (35) mates when the driving frame (15) is advanced. When an external force is applied to the driving frame (15), a cylindrical portion (35f) of the demating prevention pin (35) and the first protrusion (37) come into contact with each other. This prevents the cam pin (16) from demating from the cam groove (18). The cam pin (16) and the demating prevention pin (35) are made of common components, making it possible to reduce the number of components.
