Abstract
A wireless device includes a clock for generating clock cycles, a wireless transmission/reception circuit, a counter configured to count the number of clock cycles output by the clock since a previous point in time, and a controller. The controller is configured to append a first counter value from the counter to transmission data. The first counter value corresponds to a time of transmission for the transmission data from the wireless transmission/reception circuit. The transmission data further includes a measurement value from a sensor device and a second counter value from the counter corresponding to a time of measurement for the measurement value.
Claims20
A wireless device, comprising:
- a clock for generating clock cycles;
- a wireless transmission/reception circuit;
- a counter configured to count the number of clock cycles output by the clock since a previous point in time;
- and
- a controller configured to append a first counter value from the counter to transmission data, the first counter value corresponding to a time of transmission for the transmission data from the wireless transmission/reception circuit, the transmission data further including a measurement value from a sensor device and a second counter value from the counter corresponding to a time of measurement for the measurement value.
A wireless system, comprising:
- a sensor device configured to acquire measurement values;
- and
- a wireless device including:
- a clock for generating clock cycles;
- a wireless transmission/reception circuit;
- a counter configured to count the number of clock cycles output by the clock since a previous point in time;
- and
- a controller configured to append a first counter value from the counter to transmission data, the first counter value corresponding to a time of transmission for the transmission data from the transmission/reception circuit, wherein
- the transmission data further includes a measurement value from the sensor device and a second counter value from the counter corresponding to a time of measurement for the measurement value.
A method of transmitting measurement data obtained from a sensor device without an internal clock, the method comprising:
- counting a number of clock cycles output by a clock in a wireless device to provide a counter value corresponding to the number of clock cycles since a previous point in time;
- transmitting a measurement counter value to the sensor device;
- receiving a measurement value from the sensor device in conjunction with the previously transmitted measurement counter value;
- and
- associating the measurement value and the measurement counter value with a current counter value and then transmitting the measurement value, the measurement counter value, and the associated current counter value to an external device.
