  • Patent number: 11395628
    Abstract: A method and apparatus provides a service based on biometric information. A bioelectrical impedance of a user is measured at a first time point to obtain a first value representing biometric information of the user. At least one processor predicts the biometric information of the user at a third time point subsequent to the first time point to obtain a third value, based on the first value representing biometric information of the user at the first time point and a second value representing the biometric information at a second time point prior to the first time point. The processor calculates a difference between a fourth value representing a target related to the biometric information of the user, input by the user in advance, and the third value. Information regarding a health management service is output based on the difference between the fourth value and the third value.

    Abstract: A clamp electrode apparatus comprises first and second clamps which are mechanically connected to form a single integrated device and arranged side by side such that a first edge of the first clamp faces a second edge of the second clamp. A channel is defined between the first and second edges for aligning a visible mark feature of a limb, such as a malleolus or ulnar head, within the opening or channel when the first and second clamps clamp the limb. When the limb is clamped with the clamp electrode apparatus multiple times, the visible mark feature can be aligned with reference to the channel. Thus, electrodes attached to the clamps contact generally the same locations even if the clamp electrode apparatus is removed after each measurement and is not kept on the limb throughout the multiple measurements.

  • Patent number: 11213218
    Abstract: A sensor is configured for measuring skin conductance. An amplifier is used to convert the skin conductance into an analog output voltage which is then converted into the digital domain by an analog-to-digital converter, so that an increase in the tonic skin conductance and the phasic skin conductance response are obtained in the digital domain. The amplifier has a non-linear logarithmic gain, with a decreasing gain for increasing skin conductance values. The sensor enables detection of increases in both tonic and phasic signals over a wide range of skin conductance. This allows the use of a lower resolution, and therefore lower cost, analog-to-digital converter.

  • Patent number: 11166648
    Abstract: Method and systems are provided for monitoring neuromuscular blockade in patients during surgical procedures. The system and method utilizes a stimulator to provide stimulation to a nerve of the patient, such as train-of-four (TOF). Following such stimulation, the system and method monitors for muscle twitch reaction and, based upon the monitored muscle twitches, the system and method creates a neuromuscular blocking trend curve. The neuromuscular blocking trend curve provides an estimated time of recovery for the patient and provides the estimated recovery time to a clinician. The estimated recovery time allows the clinician to modify treatment of the patient to accelerate recovery if required.

  • Patent number: 11132723
    Abstract: A parking meter receives data indicative of a remote payment being completed and displays an amount of time purchased by the remote payment for a parking session. The parking meter determines an amount of time remaining in the parking session and powers down at least a portion of a meter communication subsystem subsequent to receiving the data indicative of the remote payment being completed. The parking meter wakes up the powered down portion of the communication subsystem upon determining that the amount of time remaining is below a threshold time, and can receive an indication of additional time being paid for remotely, and can update the displayed time remaining to reflect the additional time.
