INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A location information transmission apparatus includes a location information measuring unit configured to receive a radio wave from outside to acquire location data, a storage unit configured to store the location data, a location information transmitting unit configured to transmit the location data stored in the storage unit to the outside, a movement detecting unit configured to detect an amount of movement, and a transmission control unit configured to, in a case where the movement detecting unit detects an amount of movement equal to or greater than a predetermined amount, cause the location data to be transmitted from the location information transmitting unit to the outside. ## Claims ### Claim 1 A location information transmission apparatus comprising: a location information acquiring unit configured to receive a radio wave from outside to acquire location data; a storage unit configured to store the location data; a transmitting unit configured to transmit the location data stored in the storage unit to the outside; a movement detecting unit configured to detect an amount of movement; and a transmission judging unit configured to, in a case where the movement detecting unit detects an amount of movement equal to or greater than a predetermined amount, cause the location data to be transmitted from the transmitting unit to the outside. ### Claim 2 (depends on 1) The location information transmission apparatus according to claim 1, further comprising; an acceleration sensor configured to detect acceleration, wherein the movement detecting unit detects the amount of movement based on acceleration data acquired from the acceleration detected by the acceleration sensor. ### Claim 3 (depends on 1) The location information transmission apparatus according to claim 1, wherein the movement detecting unit detects the amount of movement based on the location data received at the location information acquiring unit. ### Claim 4 (depends on 1) The location information transmission apparatus according to claim 1, wherein the transmission judging unit judges whether or not to cause an information block to be transmitted every time one block of the information block is acquired, assuming that the location data acquired within a first predetermined time period or a plurality of pieces of the location data acquired a first predetermined number of times is the information block. ### Claim 5 (depends on 4) The location information transmission apparatus according to claim 4, wherein the transmission judging unit causes the information block to be transmitted also in a case where the movement detecting unit does not detect the amount of movement equal to or greater than the predetermined amount, when a second predetermined time period elapses after the information block is transmitted last time, or when it is continuously judged that the information block is not transmitted a second predetermined number of times after the information block is transmitted last time. ### Claim 6 (depends on 4) The location information transmission apparatus according to claim 4, wherein the movement detecting unit identifies a type of movement according to the amount of movement, and the transmission judging unit changes a criterion for judging whether or not to cause the information block to be transmitted according to an identification result of the type of the movement. ### Claim 7 (depends on 6) The location information transmission apparatus according to claim 6, wherein the type of the movement includes walking, running, and being aboard a moving body. ### Claim 8 (depends on 7) The location information transmission apparatus according to claim 7, wherein, in a case where it is identified by the movement detecting unit that the type of the movement is walking, the transmission judging unit judges whether or not to cause the information block to be transmitted every time a plurality of blocks of the information block are acquired. ### Claim 9 (depends on 1) The location information transmission apparatus according to claim 1, wherein the movement detecting unit detects a stationary state or a movement state, and in a case where the movement detecting unit detects that a state shifts from the stationary state to the movement state, the transmission judging unit causes the location data to be transmitted from the transmitting unit to the outside. ### Claim 10 (depends on 9) The location information transmission apparatus according to claim 9, wherein, assuming that the location data acquired within a first predetermined time period or a plurality of pieces of the location data acquired a first predetermined number of times is an information block, the transmission judging unit judges whether or not to cause the information block to be transmitted every time one block of the information block is acquired in a case where the movement detecting unit detects the movement state, and judges whether or not to cause the information block to be transmitted every time the movement detecting unit acquires a plurality of blocks of the information block in a case where the movement detecting unit detects the stationary state. ### Claim 11 (depends on 2) The location information transmission apparatus according to claim 2, wherein the movement detecting unit detects a stationary state or a movement state based on the acceleration data acquired from acceleration detected by the acceleration sensor every third predetermined time period. ### Claim 12 (depends on 2) The location information transmission apparatus according to claim 2, wherein the movement detecting unit detects a stationary state or a movement state based on the acceleration data acquired from acceleration detected by the acceleration sensor every third predetermined time period and the location data acquired by the location information acquiring unit. ### Claim 13 (depends on 11) The location information transmission apparatus according to claim 11, wherein the acceleration data is data obtained by averaging acceleration acquired at a sampling rate smaller than the third predetermined time period. ### Claim 14 (depends on 12) The location information transmission apparatus according to claim 12, wherein the acceleration data is data obtained by averaging acceleration acquired at a sampling rate smaller than the third predetermined time period.
