Abstract: To assist a user in the correct performance of an activity, video data is acquired. A pose of the user is determined from the video data and an avatar is generated representing the user in the pose. The pose of the user is compared to one or more other poses representing correct performance of the activity to determine one or more differences that may represent errors by the user. Depending on the activity that is being performed, some errors may be presented to the user during performance of the activity, while other errors may be presented after performance of the activity has ceased. To present an indication of an error, a specific body part or other portion of the avatar that corresponds to a difference between the user's pose and a correct pose may be presented along with an instruction regarding correct performance of the activity.

Abstract: Systems, devices, and methods for encoding information bits for storage, including encoding information bits and balance bits to obtain a first bit chunk of a first arrangement; permuting the first bit chunk to obtain a second bit chunk of a second arrangement; encoding the second bit chunk to obtain a third bit chunk of the second arrangement; permuting a first portion of the third bit chunk to obtain a fourth bit chunk of the first arrangement, and encoding the fourth bit chunk to obtain a fifth bit chunk of the first arrangement; permuting a second portion of the third bit chunk, and adjusting the balance bits based on the fifth bit chunk and the permutated second portion of the third bit chunk; adjusting the first arrangement based on the adjusted balance bits, and obtaining a codeword based on the adjusted first arrangement; and transmitting the codeword to a storage device.

Abstract: A vehicle, radar system of a vehicle and method of extending a range of the radar system. The radar system includes a transmitter antenna, a receiver antenna and a processor. The transmitter antenna transmits a reference signal. The receiver antenna receives an echo signal in response to reflection of the reference signal from an object located at a distance outside of the range limit of the radar system, wherein the range limit indicating a frequency sampling range. The processor generates a frequency peak for the object from the received echo signal, wherein the frequency peak lies outside of the frequency sampling range, shifts the frequency peak to within the frequency sampling range, and determines a range of the object using the frequency-shifted peak.
