Abstract

In one embodiment of this invention, when a transmission device transmits main information and additional information associated with the main information to a reception device, the transmission device first transmits the additional information in bulk to the reception device, generates transmission summary information relating to the additional information on the basis of the additional information, and transmits the main information to the reception device together with the transmission summary information associated with the transmitted additional information. Meanwhile, the reception device receives and stores the additional information transmitted from the transmission device, generates reception summary information on the basis of the received additional information, and stores the generated reception summary information into a storage unit in association with the additional information from which the reception summary information has been generated. The reception device then receives the main information and transmission summary information transmitted from the transmission device, reads, from the storage unit, the additional information associated with the same reception summary information as the received transmission summary information, and displays the read additional information on a display unit instead of the transmission summary information.

A transmission data controller determines a frequency bandwidth according to a relay apparatus position, the frequency bandwidth being used for a first signal transmitted from a first communication apparatus, on the basis of information regarding the number of first communication apparatuses with which a relay apparatus communicates at the relay apparatus position. The transmission data controller transmits band information indicating a frequency band selected from radio frequency bands that can be used for the first signal on the basis of the determined frequency bandwidth to the first communication apparatus. The first communication apparatus transmits the first signal having a frequency included in the frequency band indicated by the band information. The relay apparatus acquires waveform data of the first signal transmitted by the first communication apparatus, and transmits the acquired waveform data to a second communication apparatus by a second signal. The second communication apparatus performs reception processing of the first signal indicated by the waveform data acquired by performing reception processing of the second signal.

Abstract

A new DC network structure is proposed that addresses various limitations of ASIC switches. In an optical network of the present disclosure, a slight time domain limitation is introduced for transmission from a network node to a same destination node. Data transmission and reception operate in a time slot scheme. A switching bandwidth in the ASIC switch has a bandwidth corresponding to average incoming traffic of a plurality of nodes, and includes a storage medium that stores and processes traffic exceeding the bandwidth. An average bandwidth for the reception ASIC switch can also be set to a bandwidth in which the maximum incoming bandwidth to the node is reduced by a coefficient F. Limiting the bandwidth of the reception ASIC switch can reduce the power consumption of the node, which is beneficial for network scalability.

Abstract

Provided is a wireless communication system in which, based on a random access scheme, a transmission opportunity (TXOP) acquired by a wireless access point is granted to a wireless station when performing uplink data transmission from the wireless station to the wireless access point and the TXOP acquired by the wireless station is granted to the wireless access point when performing downlink data transmission from the wireless access point to the wireless station, the system includes a scheduling unit for TXOP granting determining one or more wireless stations having a quality of an uplink data transmission lower than a prescribed value as TXOP responders to which the wireless access point grants the TXOP, and determining one or more wireless stations having a quality of a downlink data transmission lower than the prescribed value as TXOP holders which grant the TXOP to the wireless access point.

Abstract

A background updating device 2 comprises a background updating unit that, if a prescribed condition is satisfied, obtains a thermal image at a target time as a new background thermal image, by using: (A) a thermal image which is an image of heat generated by a real object and which is obtained by imaging a certain imaging range at the target time with a thermal camera for imaging heat generated by a real object; (B) a real object image which is an image of the real object and which is obtained by imaging the certain imaging range at the target time with a real object camera for imaging a real object; (C) a background thermal image which is a thermal image of the background of the certain imaging range; and (D) a background real object image which is a real object image of the background of the certain range. The prescribed condition is a first condition in which the difference between the thermal image and the background thermal image is greater than or equal to a first prescribed amount, and the difference between the real object image and the background real object image is smaller than or equal to a second prescribed amount.

Abstract

A background updating device 2 is provided with a background updating unit 25 that, using at least (A) a thermal image that is an image of heat generated by a real object and is obtained by photographing a given photographing range at an object time by a thermal camera for photographing the heat generated by the real object, and (B) a background thermal image that is a thermal image of a background of the given photographing range, and with a region that is a background in the terminal image at the object time being defined as a "background region", performs processing for obtaining, as a new background thermal image, what is obtained by adding, to each pixel value of the background thermal image, a value obtained by subtracting a representative value of the temperature of the background region of the background thermal image from a representative value of the temperature of the background region of the thermal image at the object time.
