Abstract: Modulation of a frequency of a transmitted optical wave includes: at least a first and second slopes for respective frequency sweeps associated with respective points in at least one of a first or second frame. A computed range and a computed velocity are determined based on combining first partial data derived from at least one measurement associated with a first backscattered portion of the transmitted optical wave with second partial data derived from at least one measurement associated with a second backscattered portion of the transmitted optical wave. The first backscattered portion is received during a frequency sweep at the first slope associated with a first point in the first frame. The second backscattered portion is received during a frequency sweep at the second slope associated with a second point in the first frame different from the first point or associated with at least one point in the second frame.

Abstract: Aspects of the present disclosure describe systems, methods, and structures for aberration correction of optical phased arrays that employ a corrective optical path difference (OPD) in the near-field of an OPA to correct or cancel out aberrations in emitted beams of the OPA including those reaching far-field distances by generating a spatially-varying OPD across the aperture of the OPA that is substantially equal and opposite to an equivalent OPD of the aberration(s).

Abstract: A foot imaging apparatus includes a support structure and a flexible membrane suspended from the support structure and configured to receive a foot thereon. The apparatus also includes a three-dimensional imager located under the flexible membrane and configured to acquire a topographical plantar image of the foot on the flexible membrane. The apparatus further includes a monitoring unit for monitoring a monitored region in order to evaluate a positioning of the foot on the flexible membrane. The monitoring unit includes a camera having a field of view, and at least one light deflector arranged to deflect light from the monitored region into the field of view of the camera. The camera acquires a monitoring image of the monitored region after deflection by the at least one light deflector. The monitoring image contains information about the positioning of the foot on the flexible membrane. A foot imaging method is also provided.

Abstract: A pet tug toy including a noise maker bladder sewn along a squeaker rope that may have pet handles or other shapes at its distal ends, and which rope extends through a tubular channel of a center section and that causes a burst of sound when the squeaker rope is pulled though the tubular channel, with the squeak sound emitted either when a squeaker in the squeaker rope is compressed by direct pressure applied by the pet to that part of the squeaker rope encompassing a squeaker bladder, or alternatively by compression of one or more of the squeak bladders positioned inside of the rope when the rope is pulled through the channel, and with the toy formed into various shapes including animal shapes such as the shape of a monkey, alligator, crocodile, cow and rabbit, for example.
