Abstract: Apparatus and methods for generating secure electronic document authentication are provided. Authentication may include formulating “electronic signatures” or any other validation of electronic information. Apparatus and methods may include capturing a target biometric feature to authenticate the electronic information. The target biometric feature may include a combination or sequence of biometric features. In some embodiments, the target biometric feature may be captured without specially prompting a user to submit a biometric feature. A captured target biometric feature may be augmented by generation of a one-time-password using a token stored locally on a mobile device. Authentication processes described herein provide more secure, accurate authentication for electronic information.

Abstract: Portable oxygen concentrator elements are described including integrated sensor/accumulator assemblies, new muffler designs, and improved airflow and internal gas connectivity. The result of the elements is an extremely compact, light reliable portable oxygen concentrator that is easy to assemble and relatively inexpensive.

Abstract: In example methods and systems described, insulin therapy for a patient can be determined. At least one of a short-acting subcutaneous insulin dosage recommendation, a correction subcutaneous insulin dosage recommendation, an intravenous insulin dosage recommendation, a recommended amount of carbohydrates to be administered to the patient, or combinations thereof, can be determined. In addition, information indicating a confirmation of a nutrition intake for the patient, and a long-acting insulin-on-board for the patient can be received, and based on this information, a required long-acting subcutaneous or intravenous insulin dosage for the patient can be determined. The short-acting subcutaneous or intravenous insulin dosage recommendation can be adjusted based, at least in part, on a difference between the long-acting insulin-on-board and the required long-acting subcutaneous or intravenous insulin dosage.

Abstract: A portable oxygen concentrator designed for medical use where the sieve beds, adsorbers, are designed to be replaced by a patient. The concentrator is designed so that the beds are at least partially exposed to the outside of the system and can be easily released by a simple user-friendly mechanism. Replacement beds may be installed easily by patients, and all gas seals will function properly after installation.

Abstract: An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

Abstract: One-time password (“OTP”) generation on a smartwatch is provided. OTP generation may include communication between an application on a smartwatch and an application on a smartphone. The request for an OTP may be received at the smartwatch. The smartwatch application may communicate with the smartphone application. An OTP may be generated within a third-party library within the smartphone application. The generated OTP may be transmitted from the smartphone application to the smartwatch application. The OTP may be displayed on the smartwatch.
