Abstract: Methods for determining nitrogen and/or sulfur containing surfactant residual concentrations in oil and/or water phases of an oil and water system, particularly produced oil and water from an oil or gas well, are provided. The methods utilize pyro-chemiluminescence/pyro-fluorescence techniques which quantify the total residual surfactants in both oil and water phases. The methods may be applied broadly in areas where quantifying or monitoring surfactant concentrations in solution is required.

Abstract: A head worn equipment and visual feedback method and device thereof. The head worn equipment includes: a support frame, an image acquiring component, a display component, and a processor. The image acquiring component and the display component are disposed on the support frame. When the head worn equipment is in use, the display component is within a visual perception range of a user. The image acquiring component is configured to acquire a captured image. The processor acquires the captured image acquired by the image acquiring component, determines an indication color for display on the basis of the captured image, and controls the display component to display the indication color, so as to indicate a viewing direction of the image acquiring component for the user.

Abstract: A virtual or augmented reality headset that enables use while leaning backwards against a head support or lying down. The front goggles of the headset are relatively small and comfortable compared to typical bulky, heavy headsets that restrict head movement. The goggles are connected to a headband that is constructed from a soft, compliant material to function as a pillow when leaning the head back against a support. The size and weight of the headset may be further reduced by moving the batteries or other components to a separate module that may be for example worn around the neck. The goggles or headband may also contain speakers that direct sound to the ears via integrated directional sound paths while leaving the ears uncovered. The goggles may have an automated mechanism to adjust the distance between left and right lenses to match a user's intraocular distance.

Abstract: The methods and apparatuses (including systems and device) described herein may be used to accurately and comfortably monitor and track body temperature using a wearable device that can be positioned inside a patient's ear for measuring the patient's temperature, sleeping quality, or other vital signs. These systems and methods may also include a base station and a remote analytics unit (e.g., software, hardware or firmware, including application software that may run on a hand-held or wearable electronics device). The inter-aural device (earplug device) may record and pre-process information that may then be adaptively passed on the remote analytics unit for further processing. The earplug device may engage the remote analytics unit with to download and process the temperature measurement data from the device, to electrically charge the device and also to communicate wirelessly with a smart phone or different types of mobile devices.

Abstract: A method involves implantably detecting changes in posture of a patient's body. Baroreflex responses to the posture changes are determined. An autonomic tone of the patient is determined based on the baroreflex responses. Based on the autonomic tone, various patient susceptibilities to disease may be determined, including susceptibilities to heart disease, arrhythmia, and/or sudden cardiac death.

Abstract: Compounds, compositions, and methods for “smart” delivery of a therapeutic, prophylactic or diagnostic agent, such as glucose-mediated delivery of insulin through glucose-sensing insulin derivatives, are provided. The insulin derivatives bind serum albumin or agglomerate in vivo. The insulin derivatives effectively dissociate to release insulin in a hyperglycemic condition, where the complexation of glucose to a glucose-sensing element alters properties of the insulin derivative leading to the dissociation. The compounds, compositions, and methods provide a delivery strategy for both self-regulated and long-term diabetes management.
