摘要： A satellite signal reception device can reliably execute a satellite signal reception process. The satellite signal reception device has a reception time setting unit 71 that sets a reception time; a timekeeping unit that keeps internal time; and a scheduled reception control unit 72 that executes a time-based reception process that operates the reception unit when the time kept by the timekeeping unit reaches the reception time. By having a scheduled reception control unit 72, the reception process can be executed when the internal time goes to the reception time set by the reception time setting unit 71. The reception process is therefore executed once a day. The satellite signal reception process can therefore be executed reliably without being affected by how the device is used, the season, weather, or other factors.

摘要： An electronic timepiece efficiently acquires leap second information, reduces power consumption, and enables displaying the correct time. A GPS wristwatch 1 has a satellite signal reception unit 10A that receives satellite signals, a power supply including a solar panel 70 and storage battery 60, a time information adjustment unit 25 that keeps time, a reception timing determination unlit 24 that operates the satellite signal reception unit 10A, receives a satellite signal, and acquires leap second information contained in the satellite signal, and a reception determination unit 23 that detects the remaining capacity of the storage battery 60. When the remaining battery capacity measured by the reception determination unit 23 is greater than or equal to a specific value, the reception timing determination unit 24 sets the reception frequency for receiving a satellite signal higher than when the remaining battery capacity is less than the specific value.

摘要： Disclosed is apparatus and a method for displaying a time code. The apparatus comprises: a plurality of reflectors (502), each reflector (502) being configured to reflect an incident signal (907, 908), each reflector (502) being switchable between a first state and a second state; and a controller (108) configured to receive time code information and control the reflectors (502) using the received time code information. In its first state, each reflector (502) has a first orientation such that an incident signal (907, 908) is reflected in a first direction. In its second state, each reflector (502) has a second orientation such that an incident signal (907, 908) is reflected in a second direction, the second orientation being different to the first orientation such that the second direction is different to the first direction. The displayed time code is used as a time stamp for measuring the image processing latency of an imaging system, particularly an hyperspectral aerial imaging system maging in different wavelength bands.

摘要： Provided is a radio-controlled wristwatch capable of determining whether or not the illuminance of light irradiating a solar cell is high on the basis of a plurality of different criteria without directly measuring an output voltage value or an output current value of the solar cell. The radio-controlled wristwatch includes: a solar cell; a control circuit which stops operation under a predetermined condition; and an illuminance detection circuit which outputs a signal indicating whether or not illuminance of light irradiating the solar cell is higher than a given threshold value. The radio-controlled wristwatch switches the given threshold value between a first illuminance threshold value and a second illuminance threshold value that is larger than the first illuminance threshold value, starts the control circuit in a stop state when a signal indicating that the illuminance is higher than the first illuminance threshold value is output, receives a satellite signal containing time information from a satellite when a signal indicating that the illuminance is higher than the second illuminance threshold value is output, and displays time corresponding to the time information contained in the received satellite signal.
