Abstract: In various examples, the disclosed techniques include receiving, from an application executing in a virtual machine (VM), a request to perform a cryptographic operation, wherein the request specifies an ephemeral key identifier and source data. The techniques also determine, using key metadata received from a trusted execution environment, a key slot identifier associated with the ephemeral key identifier, wherein the key slot identifier identifies a key slot in which a cryptographic key is stored. The techniques further cause the cryptographic operation to be performed on the source data in the trusted execution environment using the cryptographic key, where the cryptographic key used to perform the cryptographic operation is accessed from the key slot identified by the key slot identifier. The techniques further provide, to the application, a cryptographic operation result received form the trusted execution environment.

Abstract: A portable respiration monitoring system usable wherever the respiratory monitoring is needed comprises a sensor/electronic assembly having disposable sensor components, non-disposable electronic components, and a positioning device for securing the sensor components in the respiration pathway of a subject. The positioning device is envisioned as a mask, nasal cannula, a nares clip, as hanging from eyeglasses, attached to the skin by an adhesive or magnetically in proximity to the nose or mouth, in a ET tube, in a tracheostomy tube, in a CPAP machine, in a Vapotherm/Fisher Panel device, etc. The disposable sensor and non-disposable electronic components are removably coupled with one another for a duration of the respiration monitoring, and de-coupled from one another when monitoring is completed, so that the disposable sensor components are disposed of, while the non-disposable electronic components may be re-used.

Abstract: A respiration monitoring system includes a thermoelectric generator that may be mounted within a mask enclosure or free-standing, covering all or part of the nose and/or mouth of a subject. A first temperature sensor is attached to the thermoelectric generator for measuring the subject's breath. A power controller develops a difference between a preset temperature and the subject's breath temperature that is then inserted into a feedback error signal and then into a power controller which regulates the power to the thermoelectric generator to maintain a preset temperature.

Abstract: A system for monitoring the breathing status of a patient comprises a first temperature sensor and a second temperature sensor. The first temperature sensor is arranged to measure the temperature of the breathing gas of a patient. The second temperature sensor is arranged to measure an ambient temperature of the patient's surroundings. A controller is included, wherein the controller is programmed to determine a plurality of breathing-gas temperatures over time by way of a first signal received from the first temperature sensor and at least one ambient temperature using a second signal received from the second temperature sensor. The controller is programmed to analyze the plurality of breathing-gas temperatures and the at least one ambient temperature to determine a breathing status of the patient. The present invention may be embodied as a method for monitoring the breathing status of a patient.

Abstract: The present invention is a spotlight with adjustable focus that has a focus fixing mechanism to prevent inadvertent changes to the focus of the light, while still allowing user-friendly intentional adjustment of the focus. The mounting collar of the reflector assembly rotates on helical threads on the neck of the lamp assembly so that the focus of the light may be adjusted. The focus is fixed in position by a plurality of ridges and valleys on the lamp assembly that mate with corresponding ridges and valleys in the collar of the reflector assembly. The collar of the reflector assembly is sufficiently flexible or expandable so that the focus of the lamp may be intentionally changed by applying sufficient rotational force to the reflector assembly. The collar is sufficiently rigid that the reflector assembly will not rotate as a result of incidental vibrations or movement.
