Abstract:
A state finding apparatus includes an obtaining unit and a finding unit. The obtaining unit obtains a value of an angular velocity of a first object around a predetermined axis when the first object and a second object contact with each other. The finding unit finds a state of the second object based on the obtained value of the angular velocity.

A radio-controlled timepiece includes: a radio wave reception unit that receives satellite waves and extracts an incoming code sequence encoded in the received satellite waves; a counter unit that counts a date/time of the radio-controlled timepiece; and a processor that: generates an expected code sequence containing at least a portion of a preamble code and a code generated on the basis of the date/time counted by the counter unit that are expected to be part of the incoming code sequence that is extracted, detects a match between the expected code sequence that has been generated and the incoming code sequence by sequentially comparing the expected code sequence with the incoming code sequence, and acquires a present date/time, as indicated by the satellite waves, in accordance with a detection timing of the match, as measured by the data/time counted by the counter unit.
Abstract:
A patch antenna includes a dielectric body, radiation element, earth conductor and feed member. The dielectric body increases in cross-sectional area from a first end toward a second end thereof. The radiation element is disposed on a surface of the dielectric body, and each side of the radiation element has a length adjusted based on the frequency of a radio wave to be received and the effective permittivity of the dielectric body. The earth conductor is disposed on the bottom surface of the dielectric body. The feed member is electrically connected to the radiation element.
Abstract:
A state estimation apparatus has a three-axis angular velocity sensor and a state estimation unit. The three-axis angular velocity sensor obtains a value of an angular velocity around a predetermined axis in a tennis racket when a tennis ball and the tennis racket come into contact. The state estimation unit estimates a contact position of the tennis ball on the tennis racket based on the obtained value of the angular velocity.
