Abstract: Systems and methods providing vehicle access using identified biometric data are provided herein. An example method includes storing a first biometric input for a user in a database; receiving a ride reservation from the user, the ride reservation having at least a pickup location; activating a biometric input device associated with a vehicle when the vehicle arrives at the pickup location to obtain a second biometric input for the user; authenticating the user by comparing the first biometric input with the second biometric input; and granting access to the vehicle when the first biometric input substantially matches the second biometric input.

Abstract: In various embodiments, the present disclosure relates to systems, methods, and computer-readable media for the detection of vehicle (e.g., a scooter) riding behavior. In particular, a method is described, the method including: determining first sensor data received from one or more sensors associated with a device, wherein the first sensor data is associated with a vehicle and with a time domain; determining, by the at least one processor, based on the first sensor data, second sensor data associated with a frequency domain, wherein to determine the second sensor data comprises to perform a Fourier transform on the first sensor data to determine Fourier coefficients associated with the first sensor data; and determining, by the at least one processor, based on the Fourier coefficients, using a machine learning algorithm, a type of the vehicle.

Abstract: In an example embodiment of the disclosed technology, a system can comprise a pain stimulator such as a thermal probe and a device for evaluating biological and/or neurological feedback that can provide data relating to a patient's physiological and/or neurological state. Embodiments of the disclosed technology may further comprise a computing device for implementing various aspects of the technology. Aspects of the disclosed technology can be used to reduce a patient's pain-related anxiety, thus reducing a patient's pain sensitization and pain perception, which can help a patient eliminate or lessen chronic pain symptoms.

Abstract: Methods, systems, and apparatuses can be operable to facilitate pausing playback of recorded multimedia or live television on a multimedia player and resuming playback from the pause point on the same or a different multimedia player. A user can pause a channel on a multimedia player and resume play of the paused channel on a different multimedia player. A user can pause a channel on a multimedia player and tune the multimedia player to a different channel without losing content associated with the paused channel.

Abstract: A system is provided that allows a customer to receive a guaranteed sales item when a sales item is not available on-hand at a retail store location. In one implementation, a limited in-store sale of an item may be provided such that if the customer meets certain criteria associated with the sale, that the customer is guaranteed the item, even if the item is not located at the retail location. In another implementation, each customer that is located at the retail store within a certain prescribed time of the sale may be guaranteed that the item is received by certain time.

Abstract: A precision Doppler effect compensator provides Doppler compensation in astic transmission by simultaneously sending a known reference signal with an information signal. The information signal and reference signal undergo identical Doppler effects. The compensator uses the Doppler shifted reference signal to sample the analog Doppler affected information signal. The analog information signals are digitally converted and stored in a first in first out shift register. The samples are read out of the FIFO at a rate corresponding to the frequency of a non-Doppler shifted reference signal so as to precisely reconstruct the information signal as transmitted. The samples read from the FIFO are reconverted from digital to analog form to be presented to a receiving modem for further information processing.

Abstract: An undersea communications system provides for improved data transmission pabilities. Two separate sources of information respectively modulate the upper and the lower sidebands of an acoustic carrier. The discretely modulated sidebands are simultaneously transmitted without the acoustic carrier or the acoustic carrier can be added to allow asynchronous or synchronous demodulation and use of the two modulating informations. Separation of the information in the two discretely modulated sidebands is assured by shifting the modulating information to ultrasonic regions and filtering out upper and lower sidebands of modulating information. Next, the shifted sidebands are modulated by an acoustic carrier which, optionally, is transmitted along with the discretely modulated upper and lower sidebands. A phase locked loop in the receiver portion assures synchronous demodulation or a crystal oscillator allows asynchronous demodulation of the discretely modulated upper and lower sidebands.

Abstract: An apparatus and method of transmitting and receiving information underwa assure improved performance characteristics. Modulating a carrier and appropriately filtering it allows the transmission of only single sideband signals or a carrier along with single sideband signals to increase the range at reduced power consumption levels. Demodulating incoming signals can be done synchronously (when the carrier is present) or asynchronously (only single sideband signals) to extract the information. When a number of carriers are modulated and, simultaneously, are transmitted and received, the system's reliability is enhanced.

Abstract: The deleterious effects of backscattering on a video image received from a urbid environment is minimized by using a vertical raster scan combined with appropriate filtering between the camera and monitor.
