  • Patent number: 8981942
    Abstract: The method, system, and computer-readable medium facilitates monitoring a vehicle operator, the environment ahead of the vehicle, and/or forces acting on the vehicle during the course of vehicle operation to determine whether the vehicle operator is impaired (e.g., distracted, drowsy, intoxicated), alerting the vehicle operator when impairment is detected, and log data relating to vehicle operator impairment for further analysis. The method, system, and computer-readable medium may monitor the vehicle operator, the environment ahead of the vehicle, and/or forces acting on the vehicle using either or both of optical sensors or accelerometers. In particular, one optical sensor may monitor the vehicle operator to detect eye blinks, head nods, head rotations, and/or gaze fixation. Another optical sensor may monitor the road ahead of the vehicle to detect lane deviation, lane centering, and time to collision. The accelerometers may detect acceleration in the direction of vehicle travel and/or lateral acceleration.

  • Publication number: 20150070177
    Abstract: A system for preventing drowsiness in a driver by employing a thermal grill. The system includes a detection module and an intervention module. The detection module monitors a driver's parameters to determine whether the driver is drowsy. If the driver is determined to be drowsy, the intervention module activates a thermal grill with interlaced hot and cold regions. This activation causes the hot regions to approach one temperature and the cold regions to approach another. Additionally, this activation leads to an uncomfortable sensation for the driver, alerts the driver, and prevents the driver from getting drowsy.

  • Patent number: 8963724
    Abstract: A system for preventing drowsiness in a driver by employing a thermal grill that includes warm and cool regions. The system includes a threshold determination module and a configuration module. The threshold determination module determines temperatures for warm and cool regions corresponding to a level below the driver's pain threshold. The warm and cool regions configured at these determined temperatures do not cause an uncomfortable sensation for an alert driver. Accordingly, the configuration module configures the thermal grill to these determined temperatures. As the driver gets drowsy, the driver's pain threshold falls, the configured thermal grill causes an uncomfortable sensation for the driver and alerts the driver.

  • Publication number: 20140225736
    Abstract: An apparatus for detecting sleep disorders, such as obstructive sleep apnea, includes a housing insertable into an ear canal of a subject. A sensor disposed within the housing measures a position of the subject's head relative to an axis of gravity. A transducer is responsive to the sensor and is capable of creating a stimulus detectable by the subject under certain conditions. In various embodiments, a controller receives signals corresponding to a pitch angle and a roll angle of the subject's head measured by the sensor, determines if the pitch and roll angles correspond to a sleep apnea inducing position, and causes the transducer to generate a stimulus upon determining that the subjects head is in the sleep apnea inducing position more than a predetermined threshold number of times. Various parameters of the stimulus may be modified with successive stimulus generation until a non-sleep apnea inducing position is detected.

    Abstract: Measured sleep alarm signaling is provided which activates an alarm in a manner that allows a user to get a predetermined amount of measured sleep, rather than just awakening the person at a specific time, or when the person has been in the bed for a certain amount of time. A method for awakening a person includes: setting a desired amount of actual sleep time; receiving measurement signals relating to the person's state of sleep over time; determining, using the received measurement signals, an actual sleep time indicating an amount of time that the person has actually slept; determining whether the actual sleep time is greater than or equal to the desired amount of actual sleep time, as a first determination result; and initiating an alarm for awakening the person using the first determination result.

  • Patent number: 8791825
    Abstract: It is possible to determine the biological state of the driver of a vehicle with high accuracy. In a biological state determination device, since a driver biological state which is the biological state of the driver is estimated on the basis of information representing the biological state of the driver, a weight is set for each driver biological state on the basis of information representing the level of possibility of erroneously estimating the driver biological state, and each driver biological state is weighted on the basis of the set weight, the weighted driver biological state becomes information in which the possibility of erroneous estimation is taken into consideration. The presence/absence of an abnormality in the biological state of the driver is determined on the basis of a plurality of weighted driver biological states, thereby improving determination accuracy of the biological state of the driver of the vehicle.
