Watch having sleep quality monitoring function

Abstract: The utility model discloses a watch having a sleep quality monitoring function, which comprises a casing, a circuit board, a vibration detecting device, a microprocessor, an alarm device, a display screen and a power supply. The microprocessor, the alarm device, the display screen and the power supply are mounted on the circuit board, the circuit board is fixed inside the casing, the vibration detecting device is fixed onto the casing and transmits movement information of a user to the microprocessor, and the microprocessor draws a sleep curve figure for the user according to the movement information and analyzes the sleep curve figure to judge sleep quality of the user so as to grade the sleep quality correspondingly. Further, the watch can automatically conclude sleep curves in a next period of time according to the sleep curve figure, and locates a time at the most sober state of the user according to the curves so as to start the alarm device. Therefore, the user can be prevented from being waken up in a deep sleep, and accordingly series problems caused by being waken up forcedly from the deep sleep of the user can be avoided.

ERS technical standards for using type III devices (limited channel studies) in the diagnosis of sleep disordered breathing in adults and children

Abstract: For more than three decades, type III devices have been used in the diagnosis of sleep disordered breathing in supervised as well as unsupervised settings. They have satisfactory positive and negative predictive values for detecting obstructive and central sleep apnoea in populations with moderately high pre-test probability of symptoms associated with these events. However, standardisation of commercially available type III devices has never been undertaken and the technical specifications can vary widely. None have been subjected to the same rigorous processes as most other diagnostic modalities in the medical field. Although type III devices do not include acquisition of electroencephalographic signals overnight, the minimum number of physical sensors required to allow for respiratory event scoring using standards outlined by the American Academy of Sleep Medicine remains debatable. This technical standard summarises data on type III studies published since 2007 from multiple perspectives in both adult and paediatric sleep practice. Most importantly, it aims to provide a framework for considering current type III device limitations in the diagnosis of sleep disordered breathing while raising research- and practice-related questions aimed at improving our use of these devices in the present and future.

Driving-time biological state determination apparatus and computer program

Abstract: PROBLEM TO BE SOLVED: To provide a technique to understand the biological state of a driver more accurately.SOLUTION: Comprising sleep predictive phenomenon detection means 621, urgency sleep phenomenon detection means 622, conscious sleepiness and low-waking running state detection means 623, and homeostasis maintenance function level determination means 624, a driving-time biological state determination apparatus is configured such that these means function in parallel. Therefore, a sleep predictive phenomenon, an urgency sleep phenomenon, or a period of resistance to light sleepiness (light level of drowsiness) or strong sleepiness occurring under consciousness, or moreover an instantaneous low-waking running state or prolonged continuous low-waking running state due to lowering of consciousness level can be determined and detected by the respective means, thereby enabling biological state of a driver to be determined more accurately than before.

Device for inducing better sleep

Abstract: A device for inducing better sleep embedded with music having a tempo of about sixty to about eighty beats-per-minute. Listening to music with a tempo of approximately 60 to approximately 80 beats-per-minute results in significantly better sleep quality, better perceived sleep quality, longer sleep duration and greater sleep efficiency. Embodiments of the device can include, among other things, an alarm clock, a pillow, mobile, sleep mask, crib or a stuffed toy for use with children. Embodiments of the device including a travel clock, travel pillow, or mobile device allowing the device to be easily transported for purposes of inducing better sleep during travel are also contemplated.
