Abstract: A disk drive apparatus determines a pattern of bits of a data signal applied to a magnetic write transducer of a heat-assisted magnetic recording apparatus. The magnetic write transducer applies a magnetic field to a recording medium in response to the data signal. A laser power signal is applied to a laser that heats the recording medium while the magnetic field is applied. The laser power signal is modulated based on the pattern of bits. The modulation reduces differences between track widths of recorded marks having different elapsed time values and/or increases a signal-to-noise ratio of the recorded marks having different elapsed time values.

Abstract: The present invention relates to a device, and software and methodology associated with a portable Automated External Defibrillator (“AED”). The portable AED works with a mobile device and software, and includes two or more cardiac pads, a battery pack, and specialized capacitor. When connected to a patient in cardiac arrest, the AED contacts Emergency Medical Services, and records patient information to be transmitted for evaluation by medical providers. The AED is able to analyze cardiac rhythms, suggests administering one or more shocks to the patient in appropriate cardiac arrhythmia, and guides a user on proper CPR technique, if enabled. The AED software can alert other personnel via a mobile device app.

Abstract: Devices, systems, and methods for promoting hand sanitization which may be mounted above or near a door handle. Hand sanitization devices include a sanitizer agent cartridge disposed inside a housing body and fluidically coupled to an actuating pump. The pump is configured to dispense the sanitizer when an actuation mechanism is pushed or pulled. The cartridge is also coupled to a pump sheath disposed below the pump so as to protect the internal components of the devices from unintentional splashing by the sanitizer agent. The hand sanitization devices may also record when the door is opened, when the sanitizer is dispensed, if the cartridge is empty, and when a user is approaching the door. The hand sanitization devices also have a user interface system configured to encourage the approaching user to sanitize their hands.
