Abstract: The present invention relates to a wearable device for healthcare and method for using the device. More specifically, the wearable device is worn on a finger for measuring the health data of the user, selected from one or more of heart rate, blood oxygen saturation, heart rate variability. Based on the measured data, the sleep quality can be monitored and recorded. Disorders such as obstructive sleep apnea (OSA), can be detected. The wearable device may include an optical sensor coupled with or embedded in a main body including a visible light emitter, an IR light emitter and a light detector being arranged along a longitudinal direction of the finger. During operation of the wearable device, the heart rate is monitored based on a detected light signal. When the heart rate is higher than an adaptive threshold, both heart rate and blood oxygen saturation are monitored.

Abstract: A testing device and method thereof verifies performance of a non-invasive physiological information detecting device. The testing device incorporates a first layer to modulate one or more electromagnetic signals, e.g., light, emitted from the non-invasive physiological information detecting device in a first predetermined manner and a second layer to process the electromagnetic signal from the first layer such that the modulated signal received at the physiological information detecting device simulates a change in the electromagnetic signal during a real detecting process. In one embodiment, the second layer modulates one or more electromagnetic signals from the first layer in a second predetermined manner, wherein at least one of the first and second layers modulates one kind of the electromagnetic signals.

Abstract: Described is a controller for a DC/DC converter of a type having N power stages, where N is a natural number greater or equal to 2. The controller comprises a decision maker module, a proportional-integral-derivative (PID) or proportional-integral (PI) control module and a transient compression control module. The decision maker module determines a first steady state mode of operation and a second transient mode of operation and is configured to switch control between said first steady state mode of operation to said second transient mode of operation when an operating parameter of one of the N power stages exhibits a predetermined operating condition relative to a predetermined operating limit and/or a predetermined, calculated or selected threshold. The PID or PI module regulates the operating parameter during said first steady state mode of operation.

Abstract: An electronic device measures physiological information of a living subject. The electronic device includes a sensor assembly, a first driving unit with an electromagnetic structure and a second driving unit. The first driving unit drives the sensor assembly to scan the living subject's skin along a scan path in a non-contact way to determine a measuring position. The second driving unit drives the sensor assembly to move towards and contact the living subject's skin to measure the physiological information based on the measuring position. In a typical embodiment, the sensor is configured under a measurement surface where a wrist of a user is put on. The sensor scans the user's wrist along a scan path under the wrist in a non-contact way and move upwards to contact the user's wrist for measuring the physiological information based on the scanning result.

Abstract: The present invention relates to different embodiments of lighting fixtures, such as troffers. A lens can be placed between a light engine and a reflector and secured in place by crimping portions of the light engine, reflector, or both to prevent the lens from moving. Troffers according to the present invention can lack a dedicated heat sink, instead sufficiently dissipating heat through the light engine. This can significantly reduce the weight of the troffer. Emitter panels can be directly mounted on a light engine inner surface, or on an internal reflector within the light engine.

The first moving unit includes a movable first car, an spring with two ends thereof abutting the housing and first car, respectively, and a lock formed between the driving unit and first car. The lock includes a first snap and a first protrusion detachably engagable with the first snap. One of the first snap and first protrusion is formed on the first car, and the other is formed on the driving unit. When the first protrusion disengages from the first snap, the spring moves the first car relative to the housing.
