Administering a sleep disorder

Abstract: Methods and apparatuses for administering a sleep disorder are provided. Embodiments include receiving, in a sleep administration module through one or more sensors of an earpiece worn within an ear of a sleeping patient, information regarding the sleep of the patient; deriving, by the sleep administration module from the information regarding the sleep of the patient, one or more biometric values capable of indicating the existence of a sleep disorder; and determining, by the sleep administration module, whether the one or more biometric values indicate that the sleeping patient is presently experiencing a sleep disorder.

Placing a computer system into a sleeping state

Abstract: A computer system enters or exits a sleeping state, such as the ACPI “S 1 ” state, in response to a sleep or wake event. Upon detecting the sleep or wake event, a system component generates a sleep or wake signal that instructs the computer to enter or exit the sleeping state. This sleep or wake signal is of a type to which the computer's processor does not respond. Therefore, a PMI signal is asserted in response to the sleep or wake signal. The PMI signal, when asserted, causes the processor to halt program execution.

A sleep timer arrangement for a television receiver

Abstract: It is desirable that a television receiver provide a prominent visual indication that it is about to automatically turn "off". On-screen display (OSD) circuitry automatically reduces the viewable picture area to a small area before turning off the receiver. Reduction of the viewable area may be performed by displaying and gradually enlarging at least one graphically-generated margin of the OSD display.

Smart Sleep Monitoring System via Passively Sensing Human Vibration Signals

Abstract: In this paper, a bed-mounted vibration sensor-based system is proposed to monitor vital parameters during sleep, including heartbeat rate (HR) and respiratory rate (RR), body movements and sleep postures. Our system enables smart healthcare that monitors daily sleep in a ubiquitous and non-invasive manner. Besides, the system is contact-free, as no external wearable devices and physical contacts are required. Furthermore, the vibration-based approach also avoids the privacy violation caused by the usage of surveillance cameras. To effectively monitor sleep status, a robust stable signal mode decomposition based HR and RR estimation method is developed for the complicated and noisy vibration signals. Besides, algorithms for body movement and sleep posture identification are also proposed based on vibration signal features. A prototype system is demonstrated with system details, showing great potentials in monitoring sleep status in a real-time user-friendly manner. Experimental results of short term and long term experiments with different participants and beds show that our system achieves satisfying accuracy compared with dedicated commercial devices.

Sleep mode control method and system for air conditioner

Abstract: The invention further provides a sleep mode control method for an air conditioner. The sleep mode control method comprises the following steps: extracting human body feature information from an acquired monitoring image; judging whether a human body is in a sleep state according to the human body feature information; and when the human body is judged to be in the sleep state, controlling the air conditioner to be switched from the current operating mode into a sleep mode, and controlling the air conditioner to operate at preset target sleep temperature. Furthermore, the invention further provides a sleep mode control system for the air conditioner. According to the sleep mode control method and the sleep mode control system for the air conditioner, the accuracy for controlling the sleep mode of the air conditioner is improved, the misjudgment rate is reduced, and the aim of saving the power can be fulfilled; and meanwhile, a user does not need to manually switch on or switch off the sleep mode, so that the air conditioner is convenient to use.
