Abstract: Methods, systems, and devices for underwater communication are described. In some examples, a communication system may comprise a transmitter configured to excite surface electromagnetic waves along a water surface, utilizing the water surface as a superlens to focus the intensity of the excited surface electromagnetic waves from an object plane of the transmitter through the water surface. The transmitter may be further configured to communicatively couple with a receiver that may be configured to detect the surface electromagnetic waves propagated from the transmitter across the water surface. Some implementations enable efficient underwater radio communication and imaging over significant distances, leveraging the superlensing effect of surface electromagnetic waves for enhanced signal propagation and reception.

Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, while accommodating growth of juvenile patients, includes pedicle screws and an extendable telescopic spinal rod of non-circular cross section.

Abstract: In a communication method, data from a plurality of channels is combined into a composite channel by writing data from the plurality of channels as one-bit symbols to a memory, and reading out the data from memory to form the composite channel. The combining of radio frames from the channels forms a coded composite transport channel for transmitting the data in the downlink. To form the coded composite transport channel, an input process is initiated to write data for each radio frame of a transport channel as one bit symbols to a memory of an interleaver. On an output side of the interleaver, an output process to read out the data stored in the memory is performed to form the coded composite transport channel.

Abstract: In the method of rate-matching, software is used to calculate at least one rate-matching parameter for data, and dedicated hardware is used to perform at least one of a puncturing and repetition process on data based on the calculated rate-matching parameter. In rate de-matching, software is again used to calculate at least one rate de-matching parameter for received data, and dedicated hardware is used to compensate for puncturing and repetition based on the calculated rate de-matching parameter.

Abstract: A system and method for ameliorating spinal column anomalies, such as scoliosis, includes bone screws which are to be implanted in the pedicle region(s) of individual to-be-derotated vertebrae and in vertebrae to which balancing forces must be applied as the spinal column is manipulated en mass to achieve an over-all correction of the condition. A pedicle screw cluster derotation tool simultaneously engages multiple pedicle screws and transmits manipulative forces to multiple vertebrae to effect a whole-spine correction. Pre-contoured spinal rods are engaged post-derotation to secure the correction.

Abstract: The present invention is a method and system for verification of telemarketing sales orders. According to an embodiment of the method, a sales agent asks a customer a set of questions related to a sales order, including questions required by government regulatory agencies and/or specified by an entity from whom an offer originates. The dialog is recorded by the sales agent's computer, call center server, a stand-alone unit, or a verifier server. After the sale has been established, the customer is presented with the option to review the transaction and accept or reject it. The review dialog, the interaction between the customer and the playback of the recorded offer, and the accept/reject decision are each recorded and archived. In certain embodiments of the invention at least the interaction between the customer and the playback of the recorded offer as well as the accept/reject decision are recorded in a verifier server rather than in the sales agent's computer, call center server, or stand-alone unit.
