摘要:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for creating an image similarity model. In one aspect, a method includes obtaining feature vectors for images in a set of images, and determining first similarity measures for unlabeled images relative to a reference image. The first similarity measures are independent of first similarity feedback between the unlabeled images and the reference image. The unlabeled images are ranked based on the first similarity measures, and a weighted feature vector is generated based, in part, on the ranking. Second similarity measures are determined, independent of second similarity feedback, for labeled images and a second reference image. The labeled images are ranked based on the second similarity measures. The weighted feature vector is adjusted based, in part, on a comparison of the ranking to a second ranking of the labeled images that is based on the second similarity feedback.
摘要:
In part, the disclosure relates to systems and methods for applying treatment energy, e.g., electromagnetic radiation such as laser radiation, to body areas having bulges and fat deposits and loose skin. Methods and systems disclosed herein are surprisingly effective in generating a desirable temperature profile in a target region (e.g., moderate hyperthermia in a range of about 42 to about 47° C.)). Such systems and methods also provide a dynamic balance of heating (via the application of optical radiation to the skin surface) and cooling, while substantially confining treatment temperatures to the treatment region (e.g., at or below the dermal-hypodermal (D/H) junction). In some aspects, systems and methods are provided that simultaneously reduce fatty deposits (e.g., through lipolysis) and tighten the skin (e.g., through the increased production of collagen) while minimizing patient discomfort and unintended damage, for example, within the epidermis and hypodermis regions adjacent the treatment region.

A remote control helicopter includes a body, a tail wing, a rotor assembly, a landing skid assembly, and a charging port on the bottom of the helicopter. The remote control for the helicopter includes an outer housing, landing skid grooves, a power switch, a throttle control stick that controls the ascent and the descent, a direction control stick that controls the turning or rotation of the helicopter, and a charging plug.

According to various embodiments, a regional oximetry sensor may include a light emitting element configured to emit light, a light detector configured to receive the light, and a memory device configured to store a baseline. The baseline stored by the memory device enables a regional oximetry monitor to display the baseline on a display of the regional oximetry monitor.

A combined physiological sensor and methods for detecting one or more physiological characteristics of a subject are provided. The combined sensor (e.g., a forehead sensor) may be used to detect and/or calculate at least one of a pulse blood oxygen saturation level, a regional blood oxygen saturation level, a respiration rate, blood pressure, an electrical physiological signal (EPS), a pulse transit time (PTT), body temperature associated with the subject, a depth of consciousness (DOC) measurement, any other suitable physiological parameter, and any suitable combination thereof. The combined sensor may include a variety of individual sensors, such as electrodes, optical detectors, optical emitters, temperature sensors, and/or other suitable sensors. The sensors may be advantageously positioned in accordance with a number of different geometries. The combined sensor may also be coupled to a monitoring device, which may receive and/or process one or more output signals from the individual sensors to display information about the medical condition of the subject. In addition, several techniques may be employed to prevent or limit interference between the individual sensors and their associated input and/or output signals.

Embodiments of the present disclosure relate to a system and method for determining a physiologic parameter of a patient. Specifically, embodiments provided herein include blood pressure cuffs that are adapted to be used in conjunction with a photoplethysmography sensor. The cuff as provided may be configured to be placed over the sensor and/or aligned in a specific manner relative to the sensor. Alternatively, the cuffs may include integral optical components.
