Abstract: A data communication function table relating to communication functions is shared between devices. Whether a communication device can operate in an autonomous communication mode or request/response communication mode can be therefore determined, the data type can be determined, the data size and data identification information can be acquired, and a file can be divided to an optimum size for transmission. Network traffic is therefore reduced and the effective communication speed is improved for data communication between devices over a network.

Abstract: In the case where a user changes a set state of apparatuses, an apparatus operation control portion repressively controls the apparatuses, in spite of an instruction of a control signal according to that change, so that an increasing amount of power consumption of the apparatuses obtained from an apparatus power consumption measuring portion will not exceed an increasing amount of the generating capacity of a generator obtained from a generating capacity measuring portion so as to gradually bring it closer to a target set state set up by the user.

Abstract: The present invention prepares air-conditioner energy consumption as teacher data in the case three indices of solar radiation amount, heat conduction amount, and clearance area are respectively changed; performs interpolation calculations to the air-conditioner energy consumption using said three indices; and stores the energy consumption interpolation information into the air-conditioner energy consumption interpolation information storage unit (35).

Abstract: In a room exit determination, a determination of presence of a body in a room is made if a movement pattern vector consisting of a room ID of movement origin, a room ID of movement destination and a movement period of time is not received from the a non-specified room response sensor within a predetermined period of time. A determination of exit from the room of a body is made only when the movement period of time in the movement pattern vector agrees with a movement period of time of past exits from the room stored in the a movement time storage if this vector is received from the non-specified room response sensor.

Abstract: Response pattern extracting unit 220 extracts absence detection response patterns including moving subject responses to be judged and presence detection response patterns that have symmetrical time component structures to these absence detection response patterns based on moving subject responses of moving subject detecting sensor 110 (at least one moving subject detecting sensor 110 is placed in respective rooms). Leaving room response pattern determining unit 230 adds flags showing leaving room response pattern to the above-mentioned absence detection response pattern when a response pattern extracted in response pattern extracting unit 220 includes a pair of time components that are in time reversal correlation with each other and practically equal to each other.

Abstract: A conventional human body sensing system using a tremor sensing-type human body sensor within a house has a problem such that the system cost becomes high because two human body sensors in each room or one human body sensor in each room plus one human body sensor in a corridor are used in order to sense a stationary person in a room so as to carry out a room exit determination.

Abstract: To simplify the structure of a discrete cosine transformation circuit for use in an audio recording/reproducing device. A selector can desirably supply a value “0” to an input terminal B of the adder/subtracter (80), so that an input to the adder/subtracter (80) via an input terminal A can be passed intact therethrough to be fed back thereto via the input terminal B. With this arrangement, direct connection between a multiplier to the input terminal B is unnecessary, and a selector which conventionally selects the direct connection and a loop back is also unnecessary. Further, since a selector (72) relating to proportional coefficients can desirably supply a value “1” to the multiplier (66), operand data inputted to the multiplier (66) can be supplied intact to the subsequent adder/subtracter (80) through the multiplier (66).

Abstract: A write address counter counts a write clock WCK and determines output as a write address, while read address counter counts a read clock RCK and determines output as a read address. The position of LSB in both the counters is shifted by the same number of bits at predetermined intervals, and the position of LSB of the read address counter before shifting is corresponded with the shifted position of the write address counter after shifting. Both the counters count and determine their outputs as write and read addresses. Thus, memory capacity can be reduced, and data can be written and read with different write and read orders.

Abstract: There is disclosed a discrete cosine transform circuit for use in a voice recording/reproducing device to solve problems that RAM in which data is stored is frequently accessed and that the power consumption is large. In discrete cosine transform, an algorithm can be constituted to include four or less items of operand data in one operation equation. Correspondingly, four registers 62-1 to 62-4 are arranged on the output side of RAM 60. The discrete cosine transform includes a predetermined regularity. For example, a plurality of operation equations using the same operand data are included in the processing. By continuously processing all of the operation equations, the data read into the registers 62-1 to 62-4 can be reused without being overwritten in another processing, so that accesses to RAM 60 can be suppressed.

Abstract: To achieve bi-directional transformation by using a single simply-structured discrete cosine transformation circuit for use in an audio recording/reproducing device. There is provided a circuit which comprises a RAM 60, a ROM 68, a multiplier 66, and an adder/subtracter 80 and is capable of performing inverted transformation of a discrete cosine transformation. The multiplier 66 multiplies operand data stored in the RAM 60 by a proportional coefficient stored in the ROM 68. The adder/subtracter 80 add/subtracts outputs of the multiplier 66. This circuit is also able to perform a characteristic operation in a forward direction, such as addition or subtraction using intact base data. Specifically, data before conversion is stored in the RAM 61, and one of them is supplied to the adder/subtracter 80 via an input terminal A.

Abstract: Nine memories (10a˜10i) are provided, out of which five memories are made memories for the present processing. Meanwhile, the remaining four memories are made memories for receiving and storing data to be inputted during the processing. Then, the memories (10a˜10i) which have accepted input data to be inputted at each duration of 1 sound group (SG) are switched to be used for processing, and the memories (10a˜10i) which have been for processing are switched to be used for receiving input data, but a memory (10a˜10i) which has stored the latest data in the memories for processing is left for processing. With this arrangement, memory capacity can be reduced.

Abstract: The liquid treating method according to the present invention introduces a bubble into liquid phase and applies vibration waves, such as ultrasonic waves, from each sides of the bubble. Collision of the vibration waves with the bubble imparts the compression pressure to the bubble. This effect is used to dissolve a gas forming the bubble into the liquid phase or to improve liquid quality of this liquid phase.
