Abstract: A wrist-worn device monitors movements of a user. A sensor assembly of the wrist-worn device is configured to detect movement of the user and generate sensor data based on the movement detected. A controller connected to the sensor assembly obtains movement data based on the sensor data. An antenna connected to the controller is configured to operate at a desired frequency when a wrist of the user is received by the device such that the movement data is wirelessly transmittable from the wrist-worn device to an electronic device. The antenna may exhibit a different design and configuration depending on the size of the wrist-worn device.

Abstract: A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

Abstract: Systems, apparatuses, and methods estimate the distance between a player and a ball by transmitting a chirp (sweep signal) to a radio tag located on the ball. During the chirp, the frequency of the transmitted signal is changed in a predetermined fashion. The radio tag doubles the transmitted frequency and returns the processed signal to a transceiver typically located on the player. The currently transmitted frequency is then compared with the received frequency to obtain a difference frequency from which an apparatus may estimate the distance. The apparatus may simultaneously receive the processed signal from the radio tag while transmitting the sweep signal.

Abstract: Systems and methods are described for detachable antennas. A wireless communications device includes: a cam body defining a rotation axis, the cam body including a retaining zone having a snap-fit receptacle; a signal pin including a first signal pin end and a second signal pin end; an antenna conductively coupled to the first signal pin end; a signal clip with a protrusion, a contact pad with a recess, and a key pin that extends from the signal pin, the key pin having a first key pin end and a second key pin end, and being snap-fit into the snap-fit receptacle. The systems and methods provide advantages in that the detachable antenna is easily replaced without tools.

Abstract: A method and apparatus are provided that improve data transmissions in a wireless network, optimized for the transmissions of voice signals, by companding data signals electrically about a spectral shaping module in data handling devices, preferably modems, at both the transmitting and receiving ends of the wireless network. At the transmitting end, the companding is performed by a compressor, electrically preceding a data de-emphasis module, and an expander, electrically succeeding the data de-emphasis module. At the receiving end, the companding is performed by a compressor, electrically preceding a data pre-emphasis module, and an expander, electrically succeeding the data pre-emphasis module.
