Abstract:
A reception unit receives global positioning system signals transmitted by a plurality of satellites to obtain satellite information. A determination unit determines whether or not a state in which the reception unit receives the global positioning system signals is a predetermined reception state. A positional calculation unit calculates a current position based on ephemeris information and almanac information when the reception state is the predetermined reception state, the ephemeris information including at least six orbital elements and being obtained from satellite information of first and second satellites among satellite information of three satellites, and the almanac information including at least six orbital elements on a general orbit of a third satellite of the three satellites.
Abstract:
Plural image pickup apparatuses can take images in accurate synchronization. An image pickup apparatus is provided with an image pickup unit for obtaining image data, a communication unit for communicating with another image pickup apparatus in synchronization, a synchronous signal generating unit for generating a synchronous signal having a predetermined cycle and synchronized with a timing of a synchronous operation by the communication unit, an image-pickup synchronous signal generating unit for generating an image-pickup synchronous signal having a predetermined cycle and synchronized with the synchronous signal generated by the synchronous signal generating unit, and an image-pickup controlling unit for determining in accordance with the image-pickup synchronous signal generated by the image-pickup synchronous signal generating unit, image-pickup timings at which the image pickup unit obtains image data.
Abstract:
An antenna of an electronic timepiece includes a ring-shaped antenna pattern formed on a top surface or bottom surface of a cover glass and another antenna pattern that is formed beneath the ring-shaped antenna pattern and is capacitively coupled with the ring-shaped antenna pattern. The resonant frequency of the antenna is determined by the antenna patterns.
Abstract:
A wireless synchronous system includes plural apparatuses and plural devices. The plural apparatuses each have a radio communication unit for performing synchronous communication with the other apparatus. The plural apparatuses each generate a radio synchronizing signal having a predetermined cycle synchronized with the synchronous communication, further generate a synchronizing signal having a cycle synchronized with the radio synchronizing signal, and determine a timing of controlling the apparatus, based on the synchronizing signal. The plural sensor devices each have a radio communication unit for performing synchronous communication with at least one of the plural apparatus. The plural sensor devices each generate a radio synchronizing signal having a predetermined cycle being synchronized with the synchronous communication, obtain detection-data representing a state of the sensor device, and determine a timing of obtaining the detection-data in accordance with the radio synchronizing signal.
