Abstract: A bicycle meter including a rechargeable battery, and a retractable USB plug movable between a retracted position and an extended position. In addition, the USB plug is connectable with a USB port to transfer data between the bicycle meter and a computer and to recharge the rechargeable battery, when the USB plug is in the extended position.

Abstract: A method of monitoring activities of a user may include receiving information about the user, determining whether the user takes a step, determining the number of steps taken by the user and the length of the steps, and determining at least one of speed of the user, distance traveled by the user, and heart rate of the user.

Abstract: A method of wireless communication between personal devices includes wirelessly transmitting and/or wirelessly receiving a message at a low data rate and with low latency data. The message may include at least one of a sync data field, a channel frequency field, a channel period field, a channel type field, a data format field, a control command field, a security field, a network field, a network level field, a manufacturer number field, a device type field, a device number field, a manufacturing date field, a model number field, a device identification field, a field of information to be communicated, and a checksum field.

Abstract: A timepiece apparatus (10) comprising: a rotatable shaft (30) operatively connected to a magnet (40); a magnetic detection device (50) to detect a magnetic field of the magnet (40) when proximal to the magnetic detection device (50); wherein if a predetermined sequence of magnetic fields is detected by the magnetic detection device (50), a predetermined operation is performed.

Abstract: A monitoring system (10) for monitoring the movement of a person in locomotion on foot, the system (10) comprising: a vibration sensor (38) to generate a signal when vibration is sensed, the sensor (38) being provided for footwear (20) of the person; a first unit (30) to wirelessly transmit the generated signal to a second unit (40) in response to sensed vibration; wherein a pulse width of the generated signal is measured to determine whether a person is taking a step.
